The application was filed on October 7, 2025, and published on April 9, 2026.
What changed
Mysten Labs, Inc. filed USPTO Patent Application US20260100839A1 for a zero-knowledge authenticator (zkAt) system. The zkAt technology enables policy-private authentication, allowing users to login to accounts without revealing authentication policies to third parties, and supports oblivious updates to authentication policies using zero-knowledge proof techniques. The system maintains privacy of the underlying relation in policy predicates.
Technology companies developing authentication systems, privacy-preserving applications, or cryptographic solutions should monitor this application through the patent examination process. The zkAt system could have implications for identity management, login flows, and privacy-preserving authentication architectures in enterprise and consumer applications.
What to do next
- Monitor patent examination progress
- Review zkAt technology for potential licensing opportunities
- Evaluate zkAt integration for authentication systems

Abstract
The present technology can allow a user to use a zero-knowledge authenticator (zkAt) to login to an account while preserving privacy of the authentication policy. More specifically, the present technology describes several implementations of a zkAt to enable policy-private authentication and to enable oblivious updates to authentication policies. The zkAt can be, for example, a zero-knowledge proof system where the underlying relation in the policy predicate remains private.
