Diary of a Tech Savant and Servant Leader - All things technology, product, and engineering leadership.
Secure multi-party computation (SMPC) enables organisations to collaborate on sensitive data analysis without directly sharing raw information. However, seemingly harmless aggregate outputs, particularly private set intersection (PSI), can leak individual-level information when analysed strategically over time. This post is based on research presented by Guo...

Homomorphic encryption is a powerful cryptographic technique that allows computations to be performed on encrypted data without decrypting it first. This blog post will introduce the concept of homomorphic encryption and demonstrate implementations using Python. What is Homomorphic Encryption? Homomorphic encryption is a form of...
Tech companies and large consumer businesses are grappling with how best to protect end-user data while maintaining pace of innovation and competitive edge.
