Abstract:
In this paper to protect copyright, ownership
and content integrity of digital media including
digital watermarking techniques. The primary
motivation of this article is to study the principles of
cryptographic primitives and watermarking schemes.
In this paper, we propose a secure verification
system for watermarked images with the intention of
copyright protection. RSA algorithm, RSA signature,
multi-signatures,, and LSB technique are employed
in the proposed system. The proposed system is
developed by C# programming language. This
projected system can withstand compression
brightness and no attack can destroy copyright of the
image, in addition, no one can alter content of
transmitted images. In this paper ,we use RSA multi
-signature algorithm to protect unauthorized
distribution and LSB technique to embed and detect
watermark.
