Image security is an essential part of communication through network. Nowadays the use of network and transmission of images has been widely increased. These images can be attacked by intruders and destroy the quality of the images or modified the images for illegal use. Considering these issues the proposed system ensuring the confidentiality, integrity and authentication of images using symmetric and asymmetric key cryptographic algorithm. Which make use of hybridization of two techniques i.e., RSA and AES for authentication and confidentiality. For improving the image integrity proposed system implemented image watermarking using LSB hiding algorithm. Watermarking is the process of hiding one image into another for copyright protection. RSA will be used for key generation and once key get generated, using AES algorithm watermarked image will be encrypted and send through a network. The receiving end the image will be decrypted and retrieved original watermark image.
