title = "Differential operation based palmprint authentication for multimedia security",
abstract = "This paper presents a novel approach of palmprint authentication for multimedia security by using the differential operation. In this approach, a differential operation is first conducted to the palmprint image in horizontal direction. And then the palmprint is encoded according to the sign of the value of each pixel of the differential image. This code is called DiffCode of the palmprint. The size of DiffCode is 128 bytes, which is the smallest one among the existing palmprint features and suitable for multimedia security. The similarity of two DiffCode is measured using their Hamming distance. This approach is tested on the public PolyU Palmprint Database and the EER is 0.6%, which is comparable with the existing palmprint recognition methods.",
