An adapting digital watermark algorithm based on the image fusion and chaos is put forward. The steps of the algorithm are: Firstly, the watermark image is pretreated in disorder using the chaos mapping. Then the NVF function of the carrier image is calculated. The strength of the watermark information is accommodated adaptively, and the watermark information is hidden in the carrier image by the...
Trusted Platform Module (TPM) provides the cryptographic functions through the Application Programming Interfaces (APIs). The specification of APIs reflects the security policies of the designers, in order to manage and protect the sensitive information of users, which is stored in the hardware module. But the security of these APIs has not guaranteed. In this paper, a formal model to describe the...
