Software security has drawn much attention recently. As an effective approach to detect software vulnerabilities and improve software security, dynamic taint analysis has been frequently researched in the last few years. In this paper, we implement a dynamic taint tracking system LTTS. In order to address the efficiency problem which exists in many of the current taint tracking systems, we also propose a taint behavior summary mechanism to optimize the system. According to our experiments, LTTS has achieved relative high efficiency compared to the existing techniques.
