Robust Image Authentication Using Two-Phase Tag Generation Algorithm
Authors(1) :-Yuvaraj V Image authentication techniques have recently gained great consideration due to its importance for a large number of multimedia applications. Digital images are increasingly transmitted over non-secure channels such as an internet. Thus, military, medical and quality control images must be protected against attempts to manipulate them; such manipulations could tamper the decisions based on these images. Hard authentication and soft authentication has some advantages and disadvantages. To overcome these drawbacks, this paper proposed hybrid design to protect the authenticity of multimedia images. The Approximate Message Authentication Code (AMAC) combines error-correcting codes with cryptographic techniques. In two phase tag generation algorithm have two tags where first tag is protect the image content by using dc elements of Discrete Cosine Transform (DCT) image and the second tag shows sensitivity of image by using ac elements of Discrete Cosine Transform (DCT) image. The proposed scheme attains better the robustness and fragility.
