Abstract: A method for multi-factor, biometrics-based, secure data signature includes generating, by a biometrics reader device, a first biometric measurement using a physical characteristic of a user. The method includes selecting, by at least one noise-resistant feature transformation and hashing module executing on a processor of a computing device, a code word in a set of code words, wherein selecting further comprises applying an error correcting code to the first biometric measurement. The method includes generating, by the at least one noise-resistant feature transformation and hashing module, a first hash, wherein generating further comprises executing a hashing algorithm and using the selected code word as input to the hashing algorithm. The method includes generating, by the at least one noise-resistant feature transformation and hashing module, a public key and a private key, using the first hash. The method includes electronically signing, with the private key, data associated with the user.
