Adding Navigation to the Package,ng algorithms are failed to solve the protection problems against geometric attacks. To solve this problem, a robust digital watermarking algorithm for medical images based on PHTs-DCT is proposed in this paper. For embedding watermark, DCT is applied to reduce the redundant data of the image, then

Aiming at the hidden dangers of copying, cutting, tampering, etc. in the dissemination of medical images, combined with the characteristics of medical images, this paper proposed a novel zero-watermarking algorithm based on Tetrolet-DCT, focusing o

However, it is still challenging to achieve a data sharing scheme, which meets the security, privacy, security, and credibility requirements. This paper proposes SDSBT, a multi-party data sharing platform based on blockchain and the trusted execution environment (TEE)

At present, there is an urgent need for solutions to ensure the normal schedule of life while reducing the spread of the epidemic. Several contact tracking solutions have been proposed in the market, but
