A novel low-complexity and low-power quantization technology based on H.264 integer transform is presented and implemented on VLSI for advanced video codec,in which the multiplication factors are modified so that it is possible to substitute few simplex additions and shifts for complex *** is optimized on resistor transistor logic level of IC design,and under the same cell CMOS technology,about 75.2%area and 76.3%power on average are saved in every quantization unit as compared with original H.264 quantization *** addition,in the context of software arithmetic, computing time is saved up to 92%.Experimental results of different video sequences with various texture characteristics have proved that the average absolute rate-distortion error is within 0.0315dB at the same bitrate in comparison with H.264.

To distinguish the reliabilities of different resources is difficult in the grid environment. For the first time the signaling game theory is applied to the research on grid resource reliability, and a grid resource reliability model based on promise is proposed in this paper. The analyses and the emulation results indicate that the resource provider should abandon the cheating motivation voluntarily. The resource demander could make right decision without other nodes' recommendations, the calculation and communication is reduced remarkably. This is a new solution to the problem of distinguishing resources reliabilities in the grid environment.

In this paper, we present two techniques. The first technique called Privacy Sensitive information dilUtin Mechanism (PSIUM) is able to prevent the misuse of data by a service provider by using a mixture of true and false sensor data. The second technique protects privacy sensitive information from being revealed to an attacker through traffic analysis by using a combination of frequently changing pseudonyms and dummy traffic.
