Examining Android Privacy Using Digital Forensics EXAMINING ANDROID PRIVACY USING DIGITAL FORENSICS A Project Presented to the faculty of the Department of Computer Science California State University, Sacramento Submitted in partial satisfaction of the requirements for the degree of MASTER OF SCIENCE in Computer Science by Jason Landsborough Fall 2013 © 2013 Jason Landsborough ALL RIGHTS RESERVED ii EXAMINING ANDROID PRIVACY USING DIGITAL FORENSICS A Project by Jason Landsborough Approved by: __________________________________, Committee Chair Isaac Ghansah, Ph.D. __________________________________, Second Reader Behnam Arad, Ph.D. ____________________________ Date iii Abstract of EXAMINING ANDROID PRIVACY USING DIGITAL FORENSICS A Project by Jason Landsborough Portable devices, such as those that run Android, allow people to do much more than ever before. Users of these devices can receive and respond to email when away from their computers. Pictures taken on GPS enabled devices can store location data, so users know where a picture was taken. Users can take a picture and immediately upload it somewhere. Specialized third-party apps extend the functionality of these devices even further, adding to the types of data being used and stored on the device. With all this new data comes risk. Because data can be stored, it can also be retrieved. This project covers many types of data acquisition methods for an Android device, to determine what information can be retrieved. All of the methods were free to use, and could be used by an untrusted third-party, such as a thief. Data was acquired from a T-Mobile G2x, an Android smartphone, consisting of data created for the project, as well as data that already existed on the device. The data consisted of: email messages, text messages, a phone call log entry, pictures, a calendar event, location data, a Skype instant message, a Facebook Post, and an Evernote note. An email message, two text messages, and two pictures, were deleted to determine if these could be recovered. iv Using the various methods used in this project, most of the data was retrieved. Portable devices are susceptible to being lost or stolen. Because of this and the results of this project, where confidentiality is warranted, additional security measures should be taken to protect the data. Approved by: __________________________________, Committee Chair Isaac Ghansah, Ph.D. ____________________________ Date v Student: Jason Landsborough I certify that this student has met the requirements for format contained in the University format manual, and that this project is suitable for shelving in the Library and credit is to be awarded for the project. __________________________, Graduate Coordinator ___________________ Nikrouz Faroughi, Ph.D. Date Department of Computer Science vi ACKNOWLEDGEMENTS I would like to thank Dr. Issac Ghansah for helping to define and refine this project, as well as for offering suggestions and advice throughout the project to make this project better.

In this session, Mr Dewanto, an Instructor with the Department of Physics, Faculty of Science and an Assistant Director for the Special Programme in Science shared his experience with using Apps. He offered solutions on why and how he used applications like Dropbox, Sugarsync, Evernote, Wunderlist, Skitch, Team Viewer and Splashtop Remote and elaborated on the pros and cons of these apps. These apps are cloud‐based, compatible across major platforms, relatively easy to use, and, most important of all, they are free. He also discussed on how these apps helped him in teaching and for effectively managing his administrative tasks. Mr Dewanto started the session by highlighting how he realised that his travelling time could be well‐spent and be made productive by using some of the free utility and productivity apps. His top priority in selecting the apps was to allow for planning and preparing lessons, managing classroom and research materials, and communicating with students anytime, anywhere and more importantly the apps would have to be versatile and compatible with the various gadgets – Office PC, home PC, MAC, iPAD and Smartphone — that he uses. He considered the following four aspects when selecting an app to identify if it meets his requirements: 1.

    Tools for Getting Organized 1. Dropbox – document storage What's Dropbox? "One place for all your stuff, wherever you are." Dropbox is a home for all your photos, docs, videos, and files. Anything you add to Dropbox will automatically show up on all your computers, phones and even the Dropbox website — so you can access your stuff from anywhere. Dropbox also makes it super easy to share with others, whether you're a student or professional, parent or grandparent. Even if you accidentally spill a latte on your laptop, have no fear! Relax knowing that your stuff is safe in Dropbox and will never be lost. Be anywhere Dropbox works hard to make sure that all your stuff is the same wherever you happen to be. Start a doc from a computer at school or work, make edits from your phone on the way home, then add finishing touches from a tablet in your living room. With apps available for all your computers, phones, and tablets, you can show off videos, automatically upload photos, or open documents from anywhere. Simple sharing Dropbox makes sharing easy. Invite your friends, family, and teammates to any folder in your Dropbox, and it'll be as if you saved that folder straight to their computer. You can send people links to specific files, photos, and folders in your Dropbox, too. This makes Dropbox perfect for team projects, sharing party photos with friends, or recording your band's debut album. Always safe Even if your computer has a meltdown or your phone goes for a swim, your stuff is always safe in Dropbox and can be restored in a snap.
