Data Hiding using Image Steganography

The color or appearance of the image remain unchanged after using different steganographic methods in this work. The image size remains unchanged. The two levels of security are provided by this proposed work. It hides the existence of undisclosed text from suspicious user. A hacker cannot decrypt the image as the undisclosed text is in addition, encrypted the use of RSA encryption algorithm. The color images are used to test the proposed LSB based steganographic technique. A unique matrix is generated and taken into consideration for LSB substitution withinside the color picture experiment. 3-d matrix is generated in RGB picture as it incorporates 3 colour additives i.e., red, green, and blue. These 3 matrices are dealt with one at a time for every colour element for LSB substitution. In this experiment, the 24-bit colour picture is used.
