A High Performance Image Authentication Algorithm on GPU with CUDA
Caiwei Lin, Lei Zhao, Jiwen Yang · International Journal of Intelligent Systems and Applications · 2011
There has been large amounts of research on image authentication method.Many of the schemes perform well in verification results; however, most of them are timeconsuming in traditional serial manners.And improving the efficiency of authentication process has become one of the challenges in image authentication field today.In the future, it's a trend that authentication system with the properties of high performance, real-time, flexible and ease for development.In this paper, we present a CUDA-based implementation of an image authentication algorithm with NVIDIA's Tesla C1060 GPU devices.Comparing with the original implementation on CPU, our CUDA-based implementation works 20x-50x faster with single GPU device.And experiment shows that, by using two GPUs, the performance gains can be further improved around 1.2 times in contras to single GPU.
