With the rapid development of the mobile Internet, Android has been the most popular mobile operating system. Due to the open nature of Android, c countless malicious applications are hidden in a large number of benign applications, which pose great threats to users. Most previous malware detection approaches mainly rely on features such as permissions, API calls, and opcode sequences. However, these approaches fail to capture structural semantics of applications. In this paper, we propose AMDroid that leverages function call graphs (FCGs) representing the behaviors of applications and applies graph kernels to automatically learn the structural semantics of applications from FCGs. We evaluate AMDroid on the Genome Project, and the experimental results show that AMDroid is effective to detect Android malware with 97.49% detection accuracy.

Mobile security is as critical as the PIN number on our ATM card or the lock on our front door. More than our phone itself, the information inside needs safeguarding as well. Not necessarily for scams, but just peace of mind. Android seems to have attracted the most attention from malicious code writers due to its popularity. The flexibility to freely download apps and content has fueled the explosive growth of smart phones and mobile applications but it has also introduced a new risk factor. Malware can mimic popular applications and transfer contacts, photos and documents to unknown destination servers. There is no way to disable the application stores on mobile operating systems. Fortunately for end-users, our smart phones are fundamentally open devices however they can quite easily be hacked. Enterprises now provide business applications on these devices. As a result, confidential business information resides on employee-owned device. Once an employee quits, the mobile operating system wipe-out is not an optimal solution as it will delete both business and personal data. Here we propose H-Secure application for mobile security where one can store their confidential data and files in encrypted form. The encrypted file and encryption key are stored on a web server so that unauthorized person cannot access the data. If user loses the mobile then he can login into web and can delete the file and key to stop further decryption process.
