Image Authentication Algorithm on GPU

As the demand for research on Image/ Content authentication has significantly increased, many authentication schemes have been proposed so far. But most of them are time consuming. This research concentrates on decreasing the time needed by an Image authentication algorithm. In this paper, we have shown a CUDA-based implementation of content authentication algorithm with NVIDIA´s GeForce 8400 GS GPU device. Compared to original implementation on CPU, CUDA-based implementation works has shown significant amount of improvement in terms of operational speed up.
