A Hybrid Approach with Watermark Encryption for Digital Data Protection.

Abstract

Now a day’s digital technology plays vital role in every segment for ease of data transmission and sharing using internet across the different corners of the universe. Security is a prime concern therefore copyright data protection, tamper proof, data authentication, and facsimile protection to the digital data has to be assured in certain techniques.A digital Watermarking technique has come into social media area to protect image security to ensure this; various security concepts have been introduced. This paper recommends hybrid approach, provides more solid grounds for an effective security of digital images i.e ARC6 (Augmented Rivest Cipher 6)   and RDM (Rational dither modulation) technique. A Hybrid approach to provide copyright protection to the digital data. The proposed method uses an encryption algorithm to encrypt the compacted input image and the resultant encrypted output is watermarked with a frequency domain watermarking algorithm. The output is the watermarked encrypted image. The experimental results produced, show that the visual clarity of the watermarked image is high and the watermarked image is of more secure.
