Encryption using biometric image-based key

Abstract

Methods and systems according to the present disclosure improve upon known biometric security systems by not permanently storing (e.g., for later comparison as in known systems) the actual image of the biometric characteristic. Instead, an image of a biometric identifier (e.g., retina, fingerprint, etc.) may be used to form a key which may be used to secure and provide access to data. The key may be formed, in embodiments, using a neural network and/or a random input (e.g., a vector of random characters), for example. The image of the biometric identifier may be discarded, and thus may not be vulnerable to theft. In an embodiment, the key may be used in a key-based encryption system.

Dependencies are inferred from the claim text.
