Abstract: Data security is maintained by assuming the consistency and accuracy of data over its entire life cycle. Security aspects come into play when it is necessary or desirable to protect the information transmission from an opponent who may present a threat to confidentiality, authenticity, data integrity and denial of service. Here, we are proposing a Row into column Modify stegno-algorithm. This is a image steganography technique in which we proposed a way to hide message behind the cover image with improved value of PSNR and good NCC value.
Keywords: Steganography algorithm, pseudo-random generator, LSB method, data hiding, image steganography.
