Optimal implementation of digital steganography in an true color images for the secrete communication

摘要

A Real life requirement motivated this case study for secure the digital communication. Hiding data with security is the highly challenging and desirable task. The purpose of this research work is to develop a secure and optimal data hiding technique in 24 bit true color image. My proposed method is flexible on size of secret message bits and allows us to embed a large amount of secret messages as well as maintaining good visual quality of stego-image. Using this method, message bits are embedded into uncertain and higher LSB layers, resulting in increased imperceptible and robustness of stego-image.
