It is difficult to formalize the causes of vulnerability, and there is no effective model to reveal the causes and characteristics of vulnerability. In this paper, a vulnerability model construction method is proposed to realize the description of vulnerability attribute and the construction of a vulnerability model. A vulnerability model based on chemical abstract machine (CHAM) is constructed to...
With the development of information technology, software plays an increasingly important role in the process of social development. However, at the same time, the number of software vulnerabilities is growing, posing a threat to national security and social stability. Therefore, some scholars and research institutions are paying their attention to the study of software vulnerability. In this paper,...
Software vulnerability remains a serious challenge to the software engineering domain over the past decade as a result of the recent technological advancement in information systems. The rapid development in software applications and failure on the part of system developers to properly analyze program codes before been released to the market increases the chance for data breaches. It is a known fact...
In this paper, we propose an improved algorithm for frontal face feature location based on Active Shape Models (ASM). There are two improvements in this algorithm. Firstly, to improve the accuracy of the initialization about average face model, we initialize the model using the size of eye and the location of the face in facial image. Secondly, to improve the accuracy and robustness of matching model...
