Computer basic education with computer science, and other subjects crossover study, their status has become unshakable. Current international computer science. Today, an important concept widely concerned over the field of computer science - calculation thinking. His definition, characteristics and development and basic computer education inseparable, especially for basic computer course teaching...
Digital images are facing trustworthy crisis with the emergence of various digital image process tools and steganography tools. Current digital image forensic methods can not evaluate the digital image's trustworthiness. Base on Dempster-Shafer (D-S) evidence theory, this paper proposed a new model which can effectively evaluate digital image trustworthiness. Instead of using Dempster's original rule...
The creditability and reliability of Web services is becoming an important factor to SOAs. In this paper, a cloud trust model is proposed to maintain the trustiness of services. Trust cloud transform which can reduce the trust date transferred is presented. Trust cloud operators which use cloud drops as the basic processing units are defined. The combination and update of the trust cloud are proposed...
With the development of Internet-based computing, we can no longer trust them to sustain the applications we depend on because IT infrastructure technologies fail to keep pace with emerging threats. Direct Anonymous Attestation (DAA) enables remote authentication of a user while preserving privacy under the user's control. The existing protocols for direct anonymous attestation of Trusted Platform...
MB1 is a very promising steganography. In this paper, a novel steganalysis scheme is presented to detect MB1. Many experiments are carried out based on high order features, and some useful propositions are learned from those experimental results. Based on those propositions we propose an effective MB1 detection algorithm. Experimental results show that the new proposed method has outperformed the...
There are rare researches on how to evaluate trust models. Notation of trust is extended to make trust models comparable. An evaluation framework of trust model is proposed. The actions?? parameters are described. Two evaluation metrics are designed to present the performance of trust models objectively. Experiments are implemented to get the evaluation metrics of Josang model and Beth model. The...
