摘要

With the increasingly use of non-secure channels such as the Internet to transmit the digital images, image authentication techniques have recently gained great attention due to its importance for data integrity of multimedia applications. This paper introduces a new digital signature method to content-based color image authentication based on a Triple-Channel Spiking Cortical Model (TSCM), which is inspired by the working principle of mammalian visual cortex neuron model. In this method, we use digital signatures produced by TSCM as color image authentication information. Some juggled images failed to authenticate by using local histogram method or local mean intensity method can be authenticate correctly by this method, because the signature of TSCM includes not only the intensities or color information but also the geometry structures or color distributions of the color images. Experiment results show that this method can not only check the validity and the completeness of the color image, but also locate the juggled areas in the juggled image.
