A cryptosystem based on palmprint feature

Biometric cryptography is a technique using biometric features to encrypt data, which can improve the security of the encrypted data and overcome the shortcomings of the traditional cryptography. This paper proposes a novel biometric cryptosystem based on palmprint features. In this system, the palmprint features, called DoG code, are extracted using Gaussian derivative filters. Then the Reed-Solomon error correcting technique and the logical XOR operation are employed to encrypt and decrypt the data. Experimental results show that this system can obtain a high security with a low false rejection rate.
