摘要：

针对目前数字图书馆信息资源因被篡改而引起的认证问题,提出一种篡改自恢复可逆认证解决方案。当对待检测图像进行完整性认证时,只需根据提取的分块检测比特即可判定待检测图像是否遭受篡改以及遭受篡改的位置。如没有遭受篡改,表明待检测图像通过完整性认证,并且能还原待检测图像至原始状态。否则,表明待检测图像没有通过完整性认证,然后可利用压缩感知重构技术对篡改内容进行恢复。

Abstract: Aim

ing at the authentication issue raised from the tampered information resources of digital library, this paper proposes a solving scheme for the reversible authentication with self-recovery of tampered content. When the detected image is authenticated, we can determine if the tamper happens and the tampered image location only by the extracted detection bits. If the tamper does not happen, then it manifests that the content of detected image passes the integrity authentication and the image can be restored to its original state. Otherwise, the integrity authentication for the content of detected image fails, and then the tampered content is recovered by compressive sensing reconstruction.

Key words: digital library, reversible authentication, tamper recovery
