Performance analysis in secured image encryption and data hiding using LSB algorithm

Cryptography and steganography play a vital role in making communication secret. Cryptography refers to the technology that encrypts data into unreadable format. Using steganography, the encrypted data are hidden inside a medium. In this paper, the impact that causes vulnerabilities after hiding each and every possible location of the pixel is analyzed experimentally. Bit planes of cover and stego images are analyzed by computing the difference in the corresponding 8-bit planes, so that one can clearly see the distortion of hidden information.
