🔒 About The Project

BlindAI is an open-source solution allowing users to query popular AI models or serve their own models with assurances that users' private data will remain private. The querying of models is done via our easy-to-use BlindAI Python library.

Data sent by users to the AI model is kept confidential at all times. Neither the AI service provider nor the Cloud provider (if applicable), can see the data.

Confidentiality is assured by hardware-enforced Trusted Execution Environments. We explain how they keep data and models safe in detail here.

There are two main scenarios for BlindAI:

  • BlindAI: Using BlindAI to query popular AI models hosted by Mithril Security.
  • BlindAI.Core: Using BlindAI's underlying technology to host your own BlindAI server instance to securely deploy your own models.

You can find our more about BlindAI and BlindAI.Core here.

🚀 Getting Started

We strongly recommend for you to get started with our Quick tour to discover BlindAI with a hands-on example using COVID-Net.

But here’s a taste of what using BlindAI could look like 🍒


transcript = blindai_preview.api.Audio.transcribe(

The patient is a 55-year old male with known coronary artery disease.


AI company's side

Uploading and deleting models

An AI company AI company want to provide their model as an an easy-to-use service. They upload it to the server, which is assigned a model ID.

response = client_1.upload_model(model="./COVID-Net-CXR-2.onnx")
MODEL_ID = response.model_id


When collaborating with clients is done, the AI company can delete their model from the server.

# AI company deletes model after use

Client's side

Running a model on confidential data

The client wants to feed their confidential data to the model while protecting it from third-party access. They connect and run the model on the following confidential image.

pos_ret = client_2.run_model(MODEL_ID, positive)
print("Probability of Covid for positive image is", pos_ret.output[0].as_flat()[0][1])

Probability of Covid for positive image is 0.890598714351654

BlindAI.Core Installation

🥇 Recommended 🥇

Deploying BlindAI on Azure DCsv3 VM

  • ✅ No requirement to have your own Intel SGX-ready device or a particular distribution.
  • ✅ Secure. Hardware security guarantees protect your data and model from any third-party access.
  • ❌ Can be more expensive than local deployment.

You can deploy the server in your Azure DCsv3 VM using our docker image with the following command:

docker run -it -e BLINDAI_AZURE_DCS3_PATCH=1 -p 9923:9923 -p 9924:9924 \
--device /dev/sgx/enclave --device /dev/sgx/provision \
-v /var/run/aesmd/aesm.socket:/var/run/aesmd/aesm.socket \
mithrilsecuritysas/blindai-server:latest /root/

For alternative deployment methods (on-premise, testing only...) or more information, visit our installation guide.
