Secure Data Transmission through Color Images using PHLSB Method

摘要

Steganography is knowledge of embedding the secrete information inside the host medium. Due to less security and embedding efficiency, some steganography algorithms can be effortlessly distinguished by steganalytical detectors. A secure data embedding scheme Polynomial based Hash Least Significant Bit (PHLSB) method is developed. Polynomial equations are powerful mathematical tool. These equations were used as secret key for hiding data in the cover object. The tentative results prove that the proposed method accomplishes high embedding capacity, less perceptual transparency. The PSNR and SC of stego object have good values, almost similar to the original object.
