Systems and methods for biometric identification

A method for electronically comparing fingerprints, the method comprising:

• receiving, by one or more processors, data representing a plurality of partial fingerprint images;
• converting, by the one or more processors, friction ridge segments in each partial fingerprint image to a plurality of digital descriptor representations including triangles representative of curvature of the friction ridge segments;
• forming, by the one or more processors, at least one tuple of digital descriptor representations, each tuple having two or more of the plurality of digital descriptor representations;
• comparing the at least one tuple with reference fingerprint data;
• and
• determining one or more possible matches of the partial electronic fingerprints in the reference fingerprint data based on the comparison.

A system for electronically comparing fingerprints comprising:

• a database configured to store data representing a plurality of partial fingerprint images;
• and
• one or more processors communicatively coupled to the database and configured to
• converting friction ridge segments in each partial fingerprint image to a plurality of digital descriptor representations including triangles representative of curvature of the friction ridge segments,
• forming, by one or more processors, at least one tuple of digital descriptor representations, each tuple having two or more of the plurality of digital descriptor representations,
• comparing the at least one tuple with reference fingerprint data, and
• determining one or more possible matches of the partial electronic fingerprints in the reference fingerprint data based on the comparison.
