一种改进的LSB彩色图像信息隐藏方法
Improved LSB-based information hiding method for color images
摘要
Abstract
In order to increase information hiding capability,and ensure security and imperceptibility of hided information, the traditional LSB⁃based information hiding method was improved in two aspects:increase of the carrier’s space capability to improve information hiding quantity,introduction of chaotic sequence to encrypt the secret information for improving the security of hidded information. Verification for the improved method was done on classical Lena image. The results show that the method can increase the imformation hiding quantity from 12.5% to 21%,while keeping the characteristics of carrier’s image vision and texture,and the introduction of chaotic sequence not only guarantees the imformation hiding safety but slao eliminates the depen⁃dence to the original carrier in the information extraction process.关键词
