Project description

Privacy Unleashed: Working with Antigranular

Antigranular is a community-led, open-source platform that combines confidential computing with differential privacy. This integration fosters a secure environment to handle and fully utilize unseen data.

Connect to Antigranular

You can activate Antigranular using the magic command %%ag. Any code that follows %%ag will run on our remote server. This server operates under restricted conditions, allowing only methods that guarantee differential privacy.

Install the Antigranular package using pip:

!pip install antigranular

Import the Antigranular library:

import antigranular as ag

To connect to the AG Enclave Server, use your client credentials and either a dataset or competition ID:

ag_client = ag.login(user_id="<user_id>", user_secret="<user_secret>",  competition="<competition_name>")

or

ag_client = ag.login(user_id="<user_id>", user_secret="<user_secret>", dataset="<dataset_name>")

A succesful login will register the cell magic %%ag.

Loading Private Datasets

Private datasets can be loaded as PrivateDataFrames and PrivateSeries using the ag_utils library. ag_utils is a package locally installed on the remote server, which eliminates the need to install anything other than the antigranular package.

The load_dataset() method allows for obtaining a dictionary of private objects. The structure of the response dictionary, along with the dataset path and private object names, will be specified during the competition.

%%ag
from op_pandas import PrivateDataFrame, PrivateSeries
from ag_utils import load_dataset 
"""
Sample response structure
{
    train_x : priv_train_x,
    train_y : priv_train_y,
    test_x : priv_test_x
}
"""
# Obtaining the dictionary containing private objects
response = load_dataset("<path_to_dataset>")

# Unpacking the response dictionary
train_x = response["train_x"]
train_y = response["train_y"]
test_x = response["test_x"]

Exporting Objects

Since the code following %%ag runs in a highly restricted environment, it's necessary to export differentially private objects to the local environment for further analysis. The export method in ag_utils allows data objects to be exported.

API info: export(obj, variable_name:str)

This command exports the remote object to the local environment and assigns it to the specified variable name. Note that PrivateSeries and PrivateDataFrame objects cannot be exported and will raise an error if you attempt to do so.

%%ag
from ag_utils import export
train_info = train_x.describe(eps=1)
export(train_info , 'variable_name')

Once exported, you can perform any kind of data analysis on the differentially private object.

# Local code block
print(variable_name)
