Secure communication using digital watermarking with encrypted text hidden in an image

Abstract

Increased data transmission through the network has led to the need for greater security in order to protect against different attacks. To transfer data safely, there are many techniques in use, such as digital watermarking, fingerprinting, cryptography, digital signature and steganography. The aim of this paper is to propose a method to send text data securely over the network using digital watermarking, steganography and cryptography techniques together in combination, to provide greater security. First, the cover image will be compressed using JPEG Compression Algorithm. The message to be sent is then encrypted using the improved RSA algorithm. Then the encrypted message bits and the bits of watermark image are embedded into the compressed cover image.
