IBM announced Identity Mixer, a new technology for protecting users’ personal data during authentication. The tool allows developers to build apps that can authenticate users’ identities using what’s known as a “zero-knowledge proof” that collects no personal data. Each transaction a user makes receives a different public key and leaves no privacy “breadcrumbs” The result is that users’ privacy is better preserved, and the service provider is spared the need to protect and secure all that extraneous data.”]
