Secured Image Transmission using Hybrid Approach with Compression
Prachi Raviraj Mendhekar, Pramod Borole · 2015
Abstract — Now-a-days secured communication is very essential against the unauthorized access, as all communications are possibly done over the internet. So we need to Trans-receive more confidential data with the more security. To provide more security we encrypt our secrete image and hide encrypted image into target image so it will provide more security. And by compressing we can we can reduce the image size so it will become easy to transmit secured image over the network. In this paper by using the improved LSB technique encrypted message can be hided into the target image.The encryption of the secret image is done by using steam cipher. So by using the hybrid combination of cryptography and steganography we provide security to our image transmission. Compression is done by using hybrid approach of DCT and DWT algorithm.
