Hiding information in BMP based on ECC and LSB algorithm

Abstract

Information hiding technology can embed specific information in the digital host. Because the host information changes little, it will not arouse the attention of the monitor. In order to improve the information hiding effect and anti-violence extraction ability, logistic chaotic mapping and ECC encryption are introduced, and random hiding of information after encryption is proposed. Before the data is hidden, the information is divided and combined, and the control information is also embedded in the BMP image to realize the improved LSB algorithm.
