【 摘 要 】

Nowadays, Cloud computing has become a very hot technology. with the emergence of cloud storage model, more and more users choose cloud to store the image data, while it brings challenges for image data security and usability due to the openness of cloud. An image authentication scheme is proposed to protect the ocean remote sensing image confidentiality on cloud, combining the Hash function and the threshold scheme, detecting the changes of the image data in sensitive regions and verifying the consistency for Encryption and Recovery images, The sensitive-region image can't be restored when the case that more than n-k out of n sub-secrets get lost or tampered happened. To avoid this, this paper divided the sensitive region image into blocks, and implemented secret sharing for each sub block, guarantee the lossless recovery of partial image and enhance the availability of image data. Through experiment contrast analysis, the algorithm can effectively prevent fraud during the process of secret image recovery, and it is more safe than the traditional methods.
