BitGlitter is an easy to use Python library that lets you embed data inside ordinary pictures or video. Store and host files wherever images or videos can be hosted. The carrier for data is the 'blocks' within the frames and not the file itself, and there are various measures to read imperfect distorted frames. What this means for you is streams are resistant to compression and distortion, and aren't broken by things such as format changes, metadata changes, etc. BitGlitter gives you a unique way to make your data more portable.

Using ordinary barcodes as a launchpad

Barcodes and QR codes are everywhere. They embed binary data (0's and 1's) in them, symbolized as black and white. While they are pretty constrained in the real world, using them for digital transfer removes many of those limits. What if you could have multiple barcodes (frames), that if read sequentially could have the capacity of many thousands of individual ones? What if we added colors to the barcodes, so a given barcode could have 2x, 6x, 24x the capacity? What if we greatly increased the size of the frames to lets say the size of a standard 1080p video, so the frames once again increase their capacity by a couple orders of magnitude. Combine all of these together, and you're able to move serious amounts of data. This is BitGlitter.

BitGlitter Default Palettes

  • Designed to survive what breaks existing steganography schemes: BitGlitter doesn't rely on reading the exact stream that it outputs at write. Because the data is in the video data itself and not in any metadata or byte format embedded in it, its resistant to format changes, resolution changes, compression, corruption, and other distortion. Not much different from how barcodes in real life are resistant.
  • Hardened against frame corruption: Virtually all video/image hosting social media type sites run your multimedia files through compression to minimize their file size. This can cause compression artifacts (visual distortions) to appear. In lossless steganography, this will completely corrupt the data, rendering it unreadable. Not BitGlitter.
    Taking in the palette used in the stream, it will "snap" incorrect colors to their nearest value, allowing you to read data from frames that have gone though a gauntlet of compression. The default write settings have been tested on several major sites, and were tweaked until there was 100% readability across tens of thousands of test frames.
  • Fully configurable stream creation: While the default values cover most uses, you have full control of the write parameters:
    • Color set: 8 default palettes to choose from that provide higher performance or greater file integrity. You can even make your own custom palettes (more on that below)
    • Block size: These are the colorful squares that hold data. They can be as small as one pixel, or as large as you'd like. Larger block sizes gives you greater data integrity, and smaller block sizes increase data capacity per frame.
    • Frame dimensions: Whether you want to output 144p compatible videos or 8K, it does it all.
    • Frame rate: If its a non-zero whole number, yep
    • Output mode: Choose from either an MP4 video output, or a series of PNG images (BitGlitter accepts and reads both), giving you greater flexibility on where you can host your data.
  • Built in file integrity: Metadata, files, and the stream and frames themselves are protected with SHA-256 hashes. Only valid data is accepted.
  • Built in encryption and file masking: Encrypt your files with AES-256, and optionally the file manifest as well, masking its contents until the correct key is used.
  • Built in compression: Payloads are compressed using max zlib settings prior to rendering, to minimize stream size. No need to zip or rar your files prior.
  • Supports very large streams: Current protocol can handle up to one exabyte in size, or ~4.3 billion rendered frames. Put simply, there's no practical limit to your stream's size.

Custom Color Showcase

What is possible with various configurations?

Because everything can be customized, you can have completely different outputs with vastly different performance characteristics (data integrity vs performance). In bold is the default parameters used which have been consistently readable on major social media sites. This is all new territory, what is readable can likely be tweaked and increased even more.

###The 2 Core Functions of BitGlitter

Ignoring the bells and whistles for now, all you need to use BitGlitter is write() and read(). Both use an assortment of default arguments to remove a lot of the complexity starting out.

  • write() takes your files and directories, and creates the BitGlitter stream (either as a video of a collection of images).
  • read() scans your BitGlitter encoded files and outputs the files/directories embedded in it.

write() -- converting files and directories into BitGlitter streams

We'll go a bit more in depth now.

write() is the function that inputs files and turns them into a BitGlitter stream. There are quite a few arguments to customize the stream, but there is only one required argument. Everything else has defaults.

input_path is an absolute path pointing to the file or directory you'd like convert into a stream.

preset_nickname=None takes in a string name for a preset. Learn more below in Preset Functions.

stream_name='' required argument to name your stream, which will be encoded into the metadata of the stream when read. 150 character limit.

stream_description='' serves as a text field to optionally put a description for the stream. No character limit.

output_directory=None is a string for the absolute path of an existing directory you'd like the stream to output to.is where you can optionally define the path of where the created media is outputted. By default, the stream outputs in a "Render Output" folder within the library's directory.

output_mode='video' controls the type of output you will have created. Your two choices are 'video', or 'image'. Video outputs a single .mp4 file, whereas image output returns all of the frames.

stream_name_file_output=False controls if outputted files will use the stream's SHA-256 hash as a name, or the provided name (stream_name) for the stream. By default, it uses the SHA-256, a 64 character hexadecimal 'fingerprint' of the stream.

max_cpu_cores=0 determines how many CPU cores you'd like to use when rendering frames. 0 is default, which is maximum.

compression_enabled=True enables or disables compression of your data, prior to rendering into frames.
This is enabled by default.

encryption_key='' optionally encrypts your data with AES-256. By default, this is disabled. The stream will not be able to be read unless the reader successfully inputs this.

file_mask_enabled=False toggles whether you want the stream manifest to be encrypted or not when your stream itself is encrypted. What this means is simpler terms is the contents of the stream will be hidden until or unless the correct encryption key is inputted. If set to False, the full contents of the stream will be visible. This only does anything when an encryption key is used.

scrypt_N=14, scrypt_R=8 and scrypt_P=1 allow you to customize the parameters of the scrypt key derivation function. You shouldn't touch this if you don't know what is. Only change these settings if you're comfortable with cryptography, and you know what you're doing! It's worth noting scrypt_N uses its argument as 2^n. Finally, if you're changing these numbers, they MUST be manually added when using read functionality, otherwise decryption will fail. Custom values are deliberately not transmitted in the stream for security reasons. Your end users of the stream must know these parameters if they are changed, otherwise BitGlitter will use the default parameters when decrypting.

stream_palette_id='6' sets the palette used in the stream, after initialization headers are ran. Takes a string of the palette's palette_id.

pixel_width=24 sets how many pixels wide each 'block' is when rendered on screen. 24 pixels is default. This is one of those values that have a large impact on readability. Having them overly large will make reading it easier, but will result in less efficient frames and require substantially longer streams. Making them very small will greatly increase their efficiency, but at the same time a lot more susceptible to read failures if the files are shrunk, or otherwise distorted. This default value offers a nice middleground.

block_height=45 sets how many blocks tall the frame will be, by default this is set to 45 (which along with block_width, creates a perfect 1080p sized frame).

block_width=80 sets how many blocks wide the frame will be. By default this is set to 80.

frames_per_second=30 sets how many frames per second the video will play at, assuming output_mode = "video" is used.

Finally we have several arguments to control logging.

logging_level='info' determines what level logging messages get outputted. It accepts three arguments- info is default and only shows core status data during read() and write(). 'debug' shows info level messages as well as debug messages from the various processes. Boolean False disables logging altogether.

logging_stdout_output=True sets whether logging messages are displayed on the screen or not. Only accepts booleans. Enabled by default.

logging_txt_output=False determines whether logging messages are saved as text files or not. Only accepts type bool. Disabled by default. If set to True, a log folder will be created, and text files will be automatically saved there.

save_statistics=False saves some fun statistics about your usage of the program- total number of blocks rendered, total frames rendered, and total payload data rendered. This updates after each successful write session. Functions to interact with this data are below.

These default values transmit data at about 80 KB/s. This is a safe starting point that should be pretty resistant to corruption.

read() -- converting BitGlitter streams back into directories and files

read() is how we input BitGlitter streams (whether images or video), and output the files and directories encoded in them. There are several other functions included to interact with these streams (changing the encryption key to decrypt the stream, removing one or all streams, changing its save path, etc). Check out Read Functions below to learn more.

Like with write(), the only argument required is the input path (file_path), except in this case it only accepts files. Supported video formats are .avi, .flv, .mov, .mp4, .wmv and supported image formats are .bmp, .jpeg, .jpg, .png, .webp. Can accept a string with a single absolute file path (image or video), or a list of strings of absolute file paths. Lists can only contain image files, videos must be one at a time. Important: When inputting image files, it is important to add the first few frames containing metadata FIRST, before adding the rest of the standard payload type frames. This metadata gives the reader important data on palettes, stream configuration, and on the payload itself. Some frames may be recognized as corrupted when this data is lacking. Once metadata is received, the order of images to input becomes irrelevant, and the library takes care of the rest.

stop_at_metadata_load=False This will break out of the function if metadata for the stream is read. This allows you to view the metadata and manifest (file/directory contents) of the stream itself, to verify the values for yourself. From there, you can choose to either re-read the file and continue getting the files, or delete it. This is a security feature to double check what the contents are, before you extract the files onto your computer. Please note that this will only run once per stream. When re-ran, the stream will continue to read and decode the files (if enabled in the arguments).

auto_unpackage_stream=True controls whether files embedded in the stream should be extracted during read as the frame data becomes available to do so. This lets you extract all files that are available each time read concludes if enabled. If disabled, you can unpackage files using the function unpackage(stream_sha256). For more information, go to Read Functions

auto_delete_finished_stream=True deletes all stream metadata and temporary files from your system once the read is complete, leaving you only with the decoded files pulled from the stream. In most cases you probably wouldn't change this, but in the event you want to view the data, you can do so here.

output_directory=None sets where files will be written as they become available through decoding. Takes in a string of an absolute path of an existing file directory. This is "set and forget", in the sense the first time a stream is recognized/created during read, the output path will be bound to the stream. Subsequent read() calls for other frames will continue to have the outputted files going to the right place.

bad_frame_strikes=25 Sets how many corrupted frames the reader is to detect before it aborts out of a video.
This allows you to break out of a stream relatively quickly if the video or images are substantially corrupted, without needing to iterate over each frame. If this is set to 0, it will disable strikes altogether and attempt to read every frame regardless of the level of corruption.

max_cpu_cores=0 determines the amount of CPU cores to use, like write(). The default value of 0 sets it to maximum available.

block_height_override=False and block_width_override=False allow you to manually input the stream's block height and block width. Normally you'll never need to use this, as these values are automatically obtained as the frame is locked onto. But for a badly corrupted or compressed frame, this may not be the case. By using the override, the reader will attempt to lock onto the screen given these parameters. Both must be filled in order for the override to work.

encryption_key=None is where you add the encryption key to decrypt the stream. Like argument output_directory, you only need this argument once, and it will bind to that save.

scrypt_n=14, scrypt_r=8, and scrypt_p=1 are values that control scrypt password hashing if your stream is encrypted. These only need to be touched if the stream creator changed the default values during write(). IF that is the case, these values must be identical to the values used during write; decryption won't work even with the correct encryption key. Please note that you can change these values even after read() with attempt_password(). See Read Functions below for more information.

logging_level='info', logging_stdout_output=True, logging_txt_output=False, and save_statistics=False are arguments as well. These are seen in write() as well; read their descriptions above to see what these do.

Custom Color Palette Functions

If you aren't happy with the 8 'official' palettes included with the library, you also have the freedom to create and use your own, to have them match with whatever aesthetic/style or performance you want. The entire process is very simple. There is nothing you have to do for other people to read streams using your custom palettes; the software automagically 'learns' and adds them through a special header on the stream, which then gives the ability for others to use your palette as well. If you want to share your palette with others without them needing to read a BitGlitter stream, we got you covered. Custom palettes can also be imported and exported with Base64 encoded share strings.

add_custom_palette(palette_name, color_set, nickname='', palette_description='') Creates a custom palette. Once it has been created, a string of its unique ID is returned to you (a SHA-256 of its values as well as a timestamp, making it more or less entirely unique to that palette).

  • palette_name is the its name which will it will be saved as. It has a max length of 50 characters.

  • palette_description is an optional field to include a brief description that will be attached with it. It has a max length of 100 characters.

  • color_set Is the actual colors that will be used in it. It can be a list of lists, or a tuple of tuples (no difference) of RGB24 values. Heres an example to give you a better idea: color_set=((0, 255, 0), (0, 0, 255)). There are a few constraints you must follow:

    • No two identical values can be added. For instance, the color black with the same RGB values twice. Each color used must be unique! The more 'different' the colors are in terms of their values, the better.
    • A minimum of two colors must be used.
    • You must have 2^n total colors (2, 4, 8, 16, 32, etc), with up to 256 currently supported.
  • nickname is an optional field that is a shorter, simple way to remember and use the palette, rather than its long generated ID. Both serve as a unique way to identify the palette.

return_palette(palette_id=None, palette_nickname=None) Returns a dictionary object of all of the palettes values.

edit_nickname_to_custom_palette(palette_id, existing_nickname, new_nickname) Allows you to change the nickname of the palette. Please note that the nickname must be unique, and no other palettes may already be using it.

export_palette_base64(palette_id=None, palette_nickname=None) Export any of your custom palettes using this. It returns a share code which anyone can use to import your palette.

import_palette_base64(base64_string) Import palettes from a unique share code (see directly above).

generate_sample_frame(directory_path, palette_id=None, palette_nickname=None, all_palettes=False, include_default=False, pixel_width=20, block_height=20, block_width=20) Generates a small 'thumbprint' frame of a palette, giving you an idea of how it would appear in a normal rendering.
directory_path is an existing directory in which it will be saved. all_palettes toggles whether you want to get a sample from a specific palette (using palette_id or palette_nickname) or all palettes saved. include_default toggles whether you want to include all default palettes in the generated output, or if you only want to generate custom palettes. The last 3 arguments let you control the exact size of the frames. You can also use this function to generate artwork or cool looking wallpapers using the palettes as well.

return_all_palettes() Returns a list of dictionary objects of all palettes in your database.

return_default_palettes() Returns a list of dictionary objects of all default palettes in your database.

return_custom_palettes() Returns a list of dictionary objects of all custom palettes in your database.

remove_custom_palette(palette_id, nickname) Deletes a custom palette.

remove_custom_palette_nickname(palette_id, existing_nickname) Removes the nickname from a given palette. This doesn't remove the palettes themselves, and they can still be accessible through their palette ID.

remove_all_custom_palette_nicknames() Removes all nicknames from all custom palettes. As said directly above, this only removes the nickname, not the actual palette.

remove_all_custom_palettes() Deletes all custom palettes, leaving only the default (hardwired) palettes.

Read Functions

During the read process, persistent data is stored in a sqlite database tracking its state. These functions give you a look inside, as well as some greater control of the reads themselves. BitGlitter automatically deletes temporary byte data for frames as soon as it can (ie, files can begin to be unpackaged). What remains of finished streams is a small, minimal view of their internal state, as well as stream metadata. Be aware that the read() argument auto_delete_finished_stream=True (default) will automatically delete these when the stream is fully decoded (ie, all frames are accounted for). For more information read about auto_delete_finished_stream above.

Final note before proceeding- many of these functions you'll see stream_sha256; this is a string of the stream's SHA-256 hash.

unpackage(stream_sha256) If unpackage_files=False was an argument in read(), this will unpackage the stream (or as much as it can from what has been scanned and decoded). A dictionary object will be returned that either outlines the actions taken, or the error(s) why unpackaging cannot take place (yet)

return_single_read(stream_sha256, advanced=False) Returns a basic dictionary object of stream read's state. Some fields may be empty depending on its state, or how many metadata headers have been decoded so far. Setting advanced to True will return all state data (for development, debugging, or if you're just curious). Returns False if SHA-256 matches no existing stream.

return_all_read_information(advanced=False) Returns a list of dictionary objects of all of the stream read states in your database. For more information on what advanced does, look directly above this.

update_decrypt_values(stream_sha256, decryption_key=None, scrypt_n=None, scrypt_r=None, scrypt_p=None) Updates values to decrypt the stream. From here, you have two paths: If file masking is enabled on the stream, attempt_metadata_decrypt() will decrypt the metadata header (necessary for extracting files from binary data), and from there you can unpackage(). Otherwise if file masking is disabled but the stream is encrypted, you can go straight to unpacking.

attempt_metadata_decrypt(stream_sha256) will attempt to decrypt the metadata from your read stream (if it is encrypted with file masking enabled), using your supplied decryption parameters (decryption key, scrypt N, scrypt R, scrypt P). Returns a dictionary object with the decoded metadata; if there is any error, it will return a brief explanation.

return_stream_manifest(stream_sha256, return_as_json=False) Returns an overview of all files included in the given stream, as well as their file size, and SHA-256 hash. Nested directory structures (if applicable) and file data are included in the returned object. Keys are quite short to minimize manifest size when being transmitted.

  • For directories: n directory name, f files in that directory (not including subdirectories), s subdirectories for that given directory.

  • For files: fn file name, rs raw file size (its true size), rh raw file hash (its true SHA-256 hash), ps processed file size (its packaged size when being transmitted), ph processed file hash (its packaged SHA-256 hash when being transmitted). Files are compressed in transit (unless you explicitly disable it in write() settings), hence the alternate size and hash for them.

return_as_json controls the format of the returned output. If set to False, it returns a dictionary object; if True, it will send a JSON string.

remove_partial_save(stream_sha256) Completely removes the stream read from the database. Be aware that read argument auto_delete_finished_stream automatically does this if enabled for the stream.

remove_all_partial_save_data() Removes all stream reads from the database.

update_stream_read(stream_sha256, auto_delete_finished_stream=None, auto_unpackage_stream=None) Is where you can update behavior when the stream unpackages.

blacklist_stream_sha256(stream_sha256) Disallow a specific SHA-256 hash of a stream to be read on your client. Will also remove the Stream Read containing that hash as well, if it exists.

return_all_blacklist_sha256() Returns a list of all blacklisted SHA-256 hashes as strings.

remove_blacklist_sha256(stream_sha256) Removes a specific SHA-256 hash. Returns True or False depending on whether it existed.

remove_all_blacklist_sha256() Removes all SHA-256 hashes from the blacklist.

return_stream_frame_data(stream_sha256) Returns a list of dict objects with data about all read/decoded frames. Warning: depending on stream size, this may be a long/resource intensive function to perform.

return_stream_file_data(stream_sha256) Returns a list of dict objects with data about all files read from the manifest. You'll get access to their name, file size, SHA-256 hash, whether they are eligible to be unpackaged, if they were already unpackaged, and other less user-friendly internal state data.

return_stream_progress_data(stream_sha256) Returns a list of dict objects with data about current 'slices' of the stream you're able to unpackage. These index numbers are 0-based and are for bits; this is the internal system BitGlitter uses to determine eligible files.

verify_is_bitglitter_file(file_path) Allows you to quickly test whether a given image or video is a valid BitGlitter stream or not, without relying on read() and possibly saving anything to the database. Attempts to lock onto the frame and read/decode the initializer header; it will return a boolean value whether that was successful or not.

Preset Functions

Presets allow you to define write() behavior (geometry, palettes, etc) and save it with a nickname, so you can quickly and easily use your favorite configurations with a single string, without needing to explictly state all parameters every time.

add_new_preset(nickname, output_mode='video', compression_enabled=True, scrypt_n=14, scrypt_r=8, scrypt_p=1, stream_palette_id='6', header_palette_id='6', pixel_width=24, block_height=45, block_width=80, frames_per_second=30) is how you add a new preset. Please note all of its default arguments are identical to default write arguments. For more information on each of these arguments, check out the write() section for arguments above.

return_preset_data(nickname) returns a dictionary object returning the full state of the preset.

return_all_preset_data() returns a list of all of the presets as dictionaries.

remove_preset(nickname) removes the preset with the nickname you gave it.

remove_all_presets() removes all saved presets.

Statistics Functions

output_stats() Returns a dictionary object displaying the following data for both reads and writes: blocks processed, frames processed, data processed.

clear_stats() All statistics reset back to zero.

General Functions

remove_session() Resets the entire state of the library. Removes statistics data, all saved streams, saved presets, and saved palettes. All settings get reverted to default, and default/included palettes are re-added. This can't be undone.

return_settings() Returns a dictionary object of all settings.

update_settings(read_path=None, read_bad_frame_strikes=None, enable_bad_frame_strikes=None, write_path=None, log_txt_path=None, log_output=None, logging_level=None, maximum_cpu_cores=None, save_statistics=None, output_stream_title=None) Allows you to update any of the settings. Use caution when changing these, as it could potentially result in crashes for invalid values.

Splitter

Roadmap

Here are a few possible directions this can move in which would increase its usefulness and versatility:

  • Command line functionality: Ability to read and write BitGlitter streams as well as use the rest of the built-in functions, straight from the terminal.
  • "Splash Screen": At the end of streams, include some cool looking rendered animation with the project logo, a brief explanation of what it is, and a URL to download the software. People not knowing what BitGlitter is will now have an idea as well as a way to download it, increasing usage and fueling development of the project. Could also include metadata about the stream itself.
  • Inline streams: Have a stream embedded in another (non-BitGlitter) video, allowing for data to be read inside a normal, human-friendly video. Rather than taking up the full video screen, the stream could be a bar on the top or bottom of the screen, or any arbitrary shape (perhaps even animated). This allows content creators to 'attach' files to their videos, much like you can attach arbitrary files to an email.
  • Moving heavy lifting away from Python: While libraries like cv2 and numpy are used which utilize C++, pure Python is used in a few heavily used functions (thousands of times per second). Moving these to Rust or C++ would substantially speed up the software, and make new use cases possible...
  • Livestream capabilities: BitGlitter streams can be 'broadcast' over live video. Reader would be able to detect data streams through visual or audio cues from the multimedia, and can process/decode on the fly. BitGlitter streams are no longer restricted to 'static' files, but are open to any kind of live-streaming data, which can be optionally compressed/encrypted through the original feature set.

Contributing

Let me know of your ideas and suggestions! There are many directions this technology can go in, and with enough interest your ideas can be future additions to this core library (as well as the desktop app). If you're looking to help with developing it.... awesome. All I ask is you're skilled with Python, and can write clean and structured code. I went out of my way to have clear variable and function names as well as a decent amount of comments scattered throughout the library- it should be relatively easy to get up to speed to understand how BitGlitter works underneath the hood.

Drop in and say hi on the Discord server:

Disclaimer

There are a few points worth bringing up on using this library:

  • Output sizes can be huge. At the end of the day, we're using far less dense storage mediums (color data in image and video frames) to hold and transmit good amounts of data. The payback, however, is giving you much greater portability in how or where you can store, host, and transmit it. Depending on the settings, stream size can be 1.01x-100x+ the size of the payload itself. Start with relatively smaller files when starting out with this library to get a better feel for this.
    For now until we get a better feel for how people are using it and how things can be fine-tuned, its a fair assumption that BitGlitter is best suited for payloads less than 50-100MB.
  • This library is completely experimental: In its current state, BitGlitter is merely a proof of concept to see if doing this was possible and if there is interest. It started as one of my first projects learning Python and programming as a whole. There is made by one person, but I'm doing my best to create a well-rounded product that accomplishes what its designed to do.

Please use the issues page or let me know on Discord if there is something not working.
