LSB based Variable Capacity Data Hiding Approach and Enhanced AES Security with Seam Carving

Steganography is a technology in ‘information hiding’ that allows us to hide a message (text, document, image, audio, video, etc.) in an image or video.LSB technique is very simple and popular data hiding method in which cover image holds on bit secret data in each pixel. So no of data bit in cover image depends on no of pixels in cover image. In this study we are going to discuss that the capacity of the cover image can be increased via incorporating two mathematical tools in it. One is compressing secret message using DCT compression and second using Seam Carving for increasing the resolution of the cover image.
