Latest Patents

Garrett’s listed patents address ways to protect digital information and authenticate users.

“Protocols with Noisy Response-Based Cryptographic Subkeys” describes a method for encrypting and retrieving digital files using a random binary key. A challenge-response mechanism generates an ordered set of responses, and selected responses encode the key’s symbols. During retrieval, the selected responses are compared with the full response set to reconstruct the key and decrypt the file.

“Pseudo-Homomorphic Authentication of Users with Biometry” presents a method for generating session keys through biometric responses to challenges. During enrollment, a password is repeatedly hashed to produce challenges that the user applies to a biological feature, with the resulting responses stored. During authentication, the process uses fewer hash iterations and compares new biometric responses with the stored responses. The number of iterations required to obtain a match serves as a session key or subkey.
