An Enhanced Image Steganography Technique using DCT, Jsteg and Data Mining Bayesian Classification Algorithm

Security of data is challenging issue and transmitting the secured data. Data is hidden is one of the techniques to the hide of the data in a secured way called Stegnography. In this paper we proposed secret image is hidden behind the cover image using Discrete Cosine Transform (DCT) and JSteg algorithm. In this algorithm all of the DCT coefficients are manipulated sequentially to hide secret image.
