—Video encryption is becoming increasingly important as multimedia applications gain more and more popularity. With a focus on the widely-used H.264 video coding standard, various encryption algorithms based on the intra prediction mode have been developed while suffering limited scrambling space and inadequate security. In this paper, the existing(More)
MP3 is a promising carrier format for covert communication, and how to secure its fidelity and integrity is a significant problem. In this paper, we propose a semi-fragile MP3 watermarking method for tamper detection by exploiting the rule of window switching during encoding. The method carries out embedding by establishing a mapping relationship between(More)
Keywords: Multi-software Reliability allocation Uncertainty Dempster–Shafer theory Differential evolution a b s t r a c t In multimedia platform with many applications, reliability allocation plays an important role in the design of a software and has attracted increasing attention in recent years. Thus far, the issues of software reliability allocation(More)
Coalitional Resource Games (CRGs) are a natural and formal framework in which agents wish to form coalitions to pool their scarce resources in order to achieve a set of goals that satisfy all members of a coalition. Thus far, many computational questions surrounding CRGs have been studied, but to our knowledge, a number of natural decision problems in CRGs(More)
In multi-agent systems, agents are inclined to form coalitions to improve individual performance and perform tasks more efficiently. However, the most existing researches assume that the desired outcome is a coalition structure that consists of disjoint coalitions where every agent that has joined a coalition is no longer available to join other coalitions,(More)
