基于差分中值定理的可逆隐藏简牍图像水印算法
A reversible hidden bamboo slips image watermarking algorithm based on mean value theorem of divided difference
摘要
Abstract
Bamboo slips image watermarking is a key technology for copyright protection,tampering detection and integrity protection of image data.However,most of the image watermarking keys cur-rently lack the supervision of authoritative institutions,which fails to achieve a good balance between perceived transparency and security.This paper takes the digital images of bamboo slips provided by Gansu Bamboo Slips Museum as the research object,and proposes a reversible hiding watermarking al-gorithm based on the mean value theorem of divided difference.The watermark key is generated by the combination of the authority department and the department of bamboo slips.In view of the uneven dis-tribution of texture and color of bamboo slips after excavation,different watermark key information af-ter splitting is embedded into the RGB three-channel of bamboo Slips image based on the mean value theorem of divided difference.When the least significant bit(LSB)is replaced,the security and percep-tion transparency of the watermark key information are further improved by using Logistic mapping.The experimental results show that the watermark embedded by the proposed algorithm has good invisi-bility,and the algorithm has high positioning accuracy for tampered positions of the attacked image.关键词
