Content-adaptive image steganography means that steganographer chooses embedding positions based on image textures. Steganalyst can also focus on detecting these positions according to image textures. Game theory is preferred to analyze the above situation. However, in previous game models, steganalyst will mistakenly identify that no bit is embedded, when the secret bit is the same as the least significant...
This paper presents a novel approach, based on static analysis, to detect format string vulnerabilities in C programs. Format string vulnerability is viewed as a finite state safety property. The analysis is expressed as a system of constraint describing how the safety state at one program point is related to the state at adjacent program points. Our analysis is inter-procedurally flow sensitive and...
