| Abstract: The growing possibilities of modern communications need the special means of security especially on computer network. The network security is becoming more important as the number of data being exchanged on the Internet increases. Therefore, the confidentiality and data integrity are requires to protect against unauthorized access and use. This has resulted in an explosive growth of the field of information hiding. In this paper, a hiding technique by using modified third-least-significant-bit (LSB3) substitution to hide text and binary image in color image is proposed (text in the red color space and binary image in the green space of color cover image). Typically LSB method is used least-significant-bit-plane (LSB 1) but here we used LSB 3 plane to increase the robustness. The protection of the text and image can be greatly improved with use of stego-key which has been used to permute the text characters and binary image bits before embedding them. Experimental results show that the stego-image is visually indistinguishable from the original cover-image. Therefore, we can embed two different secret messages in one color cover image successfully. | ||
