Digital Watermarking Using Color Image Processing Using images for transmitting secret information

Achal Kumar,Vibhav Prakash Singh


Digital watermarking can be used for transmitting secret information, by embedding that information into the images. This paper presents a technique to implement information hiding in color images using Advanced Encryption Scheme (AES-128) and Secure Hash Algorithm (SHA-512) to give a time effective algorithm. AES-128 is used to encrypt the message and SHA-512 is used to provide message authentication. Some experimental values are also given in this paper to show the effectiveness of proposed technique.
