The risk of privacy breaches by malicious programs has been increasing, and these programs have used more elaborate techniques to circumvent detection. Attacks using a collaboration of applications are especially difficult to find since distinct applications obtain privacy-sensitive data and send the data to the outside. Current mobile platforms have a security enforcement mechanism based on a sandbox to prevent direct data sharing between applications. Furthermore, several schemes have been proposed to improve the security against the attacks caused by two or more applications that communicate with each other. However, these schemes cannot monitor all the possible data-sharing methods.
