패리티 검사 기반의 고화질 정보은닉 기술

Recently Information Hiding Technology are becoming increasingly demanding in the field of international security, military and medical image Proposed method replaces LSB of each pixel with XOR(between the parity check bit of other 7 MSBs and 1 Secret bit) within one pixel. As a result, stego-image (that is, steganogram) doesn"t result in high image degradation. Proposed method provide enhanced embedding rate against existing XOR operation-based methods and show the reduced number of LSB modification.
