Systems, methods, and apparatus for biometric digital signature generation for identity verification are disclosed. In one or more embodiments, a method for identity verification of a user comprises sensing, by at least one sensor, biometric information from the user. The method further comprises generating, by a sensor device, biometric data from the biometric information. Also, the method comprises hashing, by the user device utilizing a fuzzy hash algorithm or a hash algorithm (e.g., a non-fuzzy hash algorithm), at least a portion of the biometric data to generate a biometric digital signature for the user. In addition, the method comprises comparing, by a verification node, the biometric digital signature to a previous biometric digital signature for the user. Further, the method comprises verifying, by the verification node, the user when the verification node determines that the biometric digital signature is identical to the previous biometric digital signature for the user.
