Abstract
Systems and methods for secure distribution of biometric matching processing are provided. Certain configurations include homomorphic encrypting of captured biometric information. In some configurations, the biometric information is classified without decryption between a first identity class and a second identity class. The biometric information may be formed as a feature vector. A homomorphic encrypted feature vector may be formed by homomorphic encrypting of the biometric information.

A method comprising:
- storing homomorphic encrypted (HE) biometric information in a reference gallery;
- providing HE biometric matching logic, and an access control device;
- generating biometric information to store in the reference gallery with a kiosk comprising a scanner;
- scanning a user and generating biometric information for identifying the user;
- the biometric information comprising an image;
- generating the generated HE encrypted information containing biometric data using an HE encryption algorithm;
- storing HE encrypted biometric information in a library;
- distributing the HE encrypted biometric information to a third-party computer;
- based on the reference gallery, constructing HE encrypted reference information using HE encryption logic;
- the HE Encryption logic storing HE encrypted information in the reference gallery;
- the third-party computer performing a HE biometric matching process using the HE biometric matching logic;
- the HE biometric matching logic performing a matching comparison of the HE encrypted information from the library against HE encrypted biometric information in the reference gallery to identify matching HE encrypted reference information;
- the HE biometric matching logic performing the HE biometric matching process without decrypting or having a capacity to decrypt the HE encrypted information;
- the third-party computer processing biometric information used for biometric matching, without access to underlying biometric information of the user;
- the third-party computer transmitting a message to the access control device;
- the access control device executing an access granted process when the message indicates a positive match based on the matching comparison;
- and
- the access control device executing an access denied process when the message does not indicate a positive match based on the matching comparison.
