Abstract:

For a more comprehensive understanding of the reasons leading to the Content Provider leakage in mobile terminal, this paper proposes a content leakage detection method based on context of Content Provider (CLDC). This method locate the suspect string or statement in the test procedure, by forming the library of security rules based on the leakage cause, detection path and judgment basis, and determine the rationality and accessibility of suspect strings or statements, using information flow analysis and simulation execution method. The experimental results show: CLDC can detect Content Provider leakage in different directions, and improve the detection accuracy effectively.
