Abstract
Mobile phone security has become an important aspect of security issues in wireless multimedia communications. In this paper, we focus on security issues related to mobile phone cameras. Specifically, we discover several new attacks that are based on the use of phone cameras. We implement the attacks on real phones, and demonstrate the feasibility and effectiveness of the attacks. Furthermore, we propose a lightweight defense scheme that can effectively detect these attacks. In this paper, we are going to develop an Android application such that when a user loses his/her phone, the spy camera could be launched via remote control and capture what the thief looks like as well as the surrounding environment. Then the pictures or videos along with location information (GPS coordinates) can be sent back to the device owner so that the owner can pinpoint the thief and get the phone back. We conduct a survey on the threats and benefits of spy cameras. Then we present the basic attack model and two camera based attacks: the remote- controlled real time monitoring attack and the pass code inference attack. We run these attacks along with popular antivirus software to test their stealthiness, and conduct experiment to evaluate both types of attack.
