Steganography is the art of hiding important information in various multimedia files. The sender and the intended receiver is aware of the existence of important message. Image Steganography is a technique of using an image file as a cover object. Cryptography is used to protect the information from the unintended user, by the encryption and decryption techniques, for secure communication. In this paper, LSB Steganography method is the proposed technique which focused on RGB colour image because it is uncompressed and suitable than any other image format. AES cryptography technique has also been used in the proposed method, for enhanced security. In this research, the performance of a combination of LSB-AES algorithms on various cover image sizes is analysed. To measure performance and image quality PSNR and MSE is used. The original image will be compared by the resulting image. Hence the proposed technique of steganography and cryptography is efficient for hiding the information inside the image, with more security.
