An Enhanced Least Significant Bit Steganography Technique

Message transmission through internet as medium, is becoming increasingly popular. Hence issues like information security are becoming more relevant than earlier. This necessitates for a secure communication method to transmit messages via internet. Steganography is the science of communicating secret data in several multimedia carriers like audio, text, video or image. A modified technique to enhance the security of secret information over the network is presented in this paper. In this technique, we generate stegnokey with the help of slave image. Proposed technique provides multi-level secured message transmission. Experimental results show that the proposed technique is robust and maintains image quality. Index Terms – Steganography, Least-significant-bit (LSB) substitution, XORing pixel bits, master-slave image.
