Abstract:
The development of communication technology,
security is a major concern. The widely used image
in communication process is vital to protect
important image data from unauthorized access. In
this paper, the digital signature is added to the
encoded image like additive noise. The encoding of
the image is done by using Bose-Chaudhuri
Hochquenghem (BCH) code. At the receiver end,
after the decryption of the image, the digital
signature can be used to verify the authenticity of the
image. To generate the digital signature, the wellknown
Rivest-Shamir-Adleman (RSA) public key
algorithm and MD5 Hash algorithm are used.
