Abstract: Now Smartphone’s are simply small computers with added services such as GSM, radio. Thus it is true to say that next generations of operating system will be on these Smartphone and the likes of windows, IOS and android are showing us the glimpse of this future. Android has already gained significant advantages on its counterparts in terms of market share. One of the reason behind this is the most important feature of Android is that it is open-source which makes it free and allows any one person could develop their own applications and publish them freely. This openness of android brings the developers and users a wide range of convenience but simultaneously it increases the security issues. The major threat of Android users is Malware infection via Android Application Market which is targeting some loopholes in the architecture mainly on the end-users part. Attackers can implement spy cameras in malicious apps such that the phone camera is launched automatically without the device owner’s notice, and the captured photos and videos are sent out to these remote attackers. Nowadays, people carry their phones everywhere; hence, their phones see lots of private information. If the phone camera is exploited by a malicious spy camera app, it may cause serious security and privacy problems. 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. Keywords: Camera Based Attacks, Watch Dog, anti-Thief. I. INTRODUCTION malicious software written by network hackers causing harm Mobile phones are becoming important part of our day to to its privacy. This demands the study of the Security day life specially the smart phones, since they are involved in Mechanisms for Android and on the way make it simple and keeping in touch with friends and family, doing business, user understandable making the user aware of areas where he accessing the internet and other activities. Android is a has to be careful. modern mobile platform that was designed to be truly open. Android applications make use of advanced hardware and It indicates that smart phone sales are continuously on rise software, as well as local and served data, exposed through and more and more people are becoming dependent on these the platform to bring innovation and value to consumers devices. As these smart phones are going to outnumber the Developed by the Open Handset Alliance (visibly led by world’s total population in 2014, securing these devices has Google), based on Linux platform, Android is a widely assumed paramount importance. Owners use their smart anticipated open source operating system for mobile devices phones to perform tasks ranging from everyday that provides a base operating system, an application communication with friends and family to the management middleware layer, a Java software development kit (SDK), of banking accounts and accessing sensitive Work related and a collection of system applications. The widespread data. These factors, combined with limitations in usage of mobile devices and its increasing functionalities has administrative device control through owners and security made both enterprises and consumers to rely on these devices critical applications like the banking transactions, make for their daily life. The most innovative feature of Android Android-based Smart phones a very attractive target for OS is open source because of which anybody can publish hackers, attackers and malware authors with almost any kind their applications freely on the android market. This openness of motivation.

Existing System The Android permission system gives users an opportunity to check the permission request of an application (app) before installation, few users have knowledge of what all these permission requests stand for; as a result, they fails to warn users of security risks. Meanwhile, an increasing number of apps specified to enhance security and protect user privacy have appeared in Android app markets. In addition, there are data protection apps that provide users the capability to encrypt, decrypt, sign, and verify signatures for private texts, emails, and files. Fig.1.

Siddappa, Professor Dept. of Computer Science and Engineering, SSIT, Tumkur, Karnataka, India Abstract: This project uses Android, along with cloud based APIs and the Arduino microcontroller, to create a software-hardware system that attempts to address several current problems in robotics, including, among other things, line-following, obstacle-avoidance, voice control, voice synthesis, remote surveillance, motion & obstacle detection, face detection, remote live image streaming and remote photography in panorama & time-lapse mode. The rover, built upon a portable five-layered architecture, will use several mature and a few experimental algorithms in AI, Computer Vision, Robot Kinetics and Dynamics behind-the-scene to provide its prospective user in defense, entertainment or industrial sector a positive user experience. A minimal amount of security is achieved via. a handshake using MD5, SHA1 and AES. It even has a Twitter account for autonomous social networking. Key Words: Voice Synthesis, Voice Control, Robot-User Interaction, Face Detection, Motion and Object Detection, Remote Surveillance, Panoramic and Time-lapse Photography, Line-following and Obstacle-Avoiding Robotics, AI, Computer Vision, Image Processing, Network Security Introduction Android, which is actually a software stack, running atop the Linux kernel, is one of the most successful operating systems available to mobile users today. This success can be attributed to the fact that Android makes development of application softwares ('apps') really easy by allowing developers to code in Java (among many other languages) and thus enabling them to take advantage of the innumerable packages and modules made available by the Java community.

One way to do this is to develop web applications, which are accessed from a mobile de- vice’s web browser, instead of native applications. The same web application can then be used on different platforms such as Android and iOS. However, devices such as smart phones and tablets often include cameras and sensors that a web ap- plication may want to access, but which are only accessible from native applica- tions. A framework was developed that enables web applications to communicate with native Android applications. Native applications are launched by clicking a link in the browser, and the result produced is made available to the web applica- tion through a HTTP POST request or a local web server running on the device. Key characteristics of the framework include ease of extension and the ability to enable secure (SSL) communication if desired.

Kannengießer, M. Sc. Date: April 15, 2013 I assure the single handed composition of this bachelor thesis only supported by declared resources. Munich, 15th of April, 2013 Johannes Neutze Abstract This bachelor thesis is about the development of an Android application, simulating the HomeMatic system and the XML­API v1.2, designed to control the HomeMatic system, e.g. through the HomeDroid client. Configuration of the system, handshake with HomeDroid and persistent storage of the entire system status is implemented by using standard components, like a HTTP server, a relational database and an Android graphical user interface. As a result, the user can connect to the application via HomeDroid and interact with it, like with the real hardware. First, the foundation of emulated system and the environment used to develop the application, are explained. Then the system requirements are outlined and the architecture is illustrated. Finally, the implementation of each component, the graphical user interface and its testing are described.
