Robust Watermarking Framework with DCT Based Encryption
Journal Title: INTERNATIONAL JOURNAL OF COMPUTER TRENDS & TECHNOLOGY - Year 2013, Vol 5, Issue 5
Abstract
Since several years,, the protection of multimedia data is becoming extremely important. The protection of the multimedia data might be performed with encryption or data hiding algorithms. To address the transmission time, information compression is required. If you take benefit from the character of cryptographic schemes and digital watermarking, the copyright of multimedia contents can possibly be well protected. Our objective will be to give access to the outcomes of one's image integrity and of their origin regardless of the fact that the reputation is stored encrypted. If watermarking and encryption are conducted jointly for the protection stage, watermark extraction and decryption might be applied independently. With the source end original image and watermarked encrypted image is processed. This encrypted watermark image is finally decoded at the receiver end. This proposed work proposes a novel encryption algorithm to encrypt image. The entropy of this very watermarked image and correlation coefficient of extracted watermark image is amazingly not far away from ideal values, proving the correctness of proposed algorithm. In the proposed system, a Watermarking Scheme based on DWT with encryption algorithm, will be developed to improve the robustness and protection along with security. Also experimental results show resiliency of a given scheme against large blurring attack like mean and Gaussian filtering, linear filtering Thus proving the security, effectiveness and robustness of a given proposed watermarking algorithm.
