Crypten
Crypten is an open-source Python library developed by Facebook AI Research (now Meta AI) for secure multi-party computation (MPC) and privacy-preserving machine learning. It enables developers to perform computations on encrypted data without decrypting it, allowing multiple parties to collaboratively analyze data while keeping their inputs private. The library provides a PyTorch-like interface, making it accessible for machine learning practitioners to implement privacy-enhancing techniques in their models.
Developers should learn Crypten when building applications that require data privacy, such as in healthcare, finance, or collaborative AI research, where sensitive information must be protected during analysis. It is particularly useful for implementing federated learning, secure aggregation, or any scenario where multiple entities need to compute on combined data without exposing individual inputs. By using Crypten, developers can enhance trust and compliance with regulations like GDPR or HIPAA while leveraging advanced machine learning capabilities.
