The invention belongs to the technical field of fingerprint recognition and encryption fusion in pattern recognition, and discloses an irreversible fingerprint template encryption method based on symmetric hash. The method of combining symmetric hash function with positive remainder function can strictly guarantee the irreversibility of hash operation. The security of the entire encryption algorithm is improved. Because the number of equations of the constructed hash function is less than the number of inputs, that is, the rank of the coefficient matrix of the non-homogeneous equations is equal to the rank of the augmented matrix, and is smaller than the number of equations, there are infinitely many equations in theory solution, so the input data information cannot be pushed back through the result. In addition, due to the characteristic that the output of the sine and cosine functions corresponds to infinitely many inputs, the irreversibility of the algorithm of the present invention is raised to a higher level. Even if an attacker steals the user's key and template, it cannot push back the user's original fingerprint. At the same time, in the process of hash operation, the method of combining user keys is simpler, more efficient, and more revocable.
