Abstract
This paper presents a parallel approach to improve the time complexity problem associated with sequential algorithms. An image steganography algorithm in transform domain is considered for implementation. Image steganography is a technique to hide secret message in an image. With the parallel implementation, large message can be hidden in large image since it does not take much processing time. It is implemented on GPU systems. Parallel programming is done using OpenCL in CUDA cores from NVIDIA. The speed-up improvement obtained is very good with reasonably good output signal quality, when large amount of data is processed.
