A High Capacity Information Hiding Algorithm in Color Image

One of the important objectives of information hiding research is that secret information is embed as much as possible without the perception of the carrier is affected. A hiding information algorithm of adaptive multiple plane-bit based on space domain in color image is proposed, which has low computing complexity and high capacity of information hiding. The main idea of this algorithm is to judge each pixel at first, then embed hidden information in the designated point behind the highest non-zero bit until another designated point according to the human visual characteristics. The experimental results show hidden information capacity of this algorithm is much larger than LSB algorithm, and security is much higher than LSB algorithm on the premise of that the visual effect of image is not affected.
