3. 2015 GenCyber Cybersecurity Workshop Project Overview  To come up with a unique user authentication mechanism to achieve phone security without the user having to enter a passcode to unlock their phone

4. 2015 GenCyber Cybersecurity Workshop Agenda  Deciding on project details  Use Cases  Hardware and Software choices  Tasks Accomplished  Operation of user authentication app  Survey of interest in password-free security  New Directions for Future Projects  Smartwatch sensors

5. 2015 GenCyber Cybersecurity Workshop User Story Under Consideration Unlock Student’s Phone in Dorm Room  A user story is a tool used in Agile software development to capture a description of a software feature from an end - user perspective. The user story describes the type of user, what they want and why. A user story helps to create a simplified description of a requirement.  User stories were developed keeping in mind the following:  Do they reflect the user’s mental model of protection?  Is the mechanism psychologically acceptable?  Is it close to transparent to the users?  Does it fit with their natural phone interactions?  Focus: student’s phone will unlock in their dorm room and lock at other times. This can be extended for future use cases.

6. 2015 GenCyber Cybersecurity Workshop Tasks Accomplished  A survey was conducted to evaluate user interest in a password-free mobile device authentication mechanism  An iOS app “Authenticator” was designed with authentication functionality based on fingerprint sensing and location information.  Developed by Tanya Sahin

7. 2015 GenCyber Cybersecurity Workshop Security Mechanisms  Widely used today:  Passwords / PINs  Pattern locks  Using an unlock mechanism would make it harder for unauthorized users to access valuable data

8. 2015 GenCyber Cybersecurity Workshop Burden of PIN-code Entry  Frequency of entering PIN-code  Although locking a phone may provide maximum protection, it also decreases usability by increasing PIN-code entry burden  As a result companies have launched user specific and easy unlock mechanisms:  Touch ID fingerprint reader (Apple and Samsung)

9. 2015 GenCyber Cybersecurity Workshop User Authentication Mechanisms  Bluetooth Low Energy (BLE) and Beacons  NFC (Near Field Communication)  Geofencing  Sensor capabilities 9

10. 2015 GenCyber Cybersecurity Workshop iBeacons and Geofencing  iBeacon is Apple's implementation of Bluetooth low-energy (BLE) wireless technology to provide location-based information and services to iPhones and other iOS devices.implementation of Bluetooth low-energy (BLE) wireless technology  The beacons themselves are small, cheap Bluetooth transmitters. Apps installed on your iPhone listen out for the signal transmitted by these beacons and respond accordingly when the phone comes into range.  For example, if you pass a beacon in a shop, the retailer's app (assuming you have it installed) could display a special offer alert for you. On a visit to a museum, the museum's app would provide information about the closest display, using your distance from beacons placed near exhibits to work out your position

11. iBeacons

12. 2015 GenCyber Cybersecurity Workshop Geo-fencing  Geofencing is a feature in a software program that uses the global positioning system (GPS) or radio frequency identification (RFID) to define geographical boundaries.  Our app uses iBeacons to define the geofence. When user enters the defined geofence, phone unlocks automatically

13. 2015 GenCyber Cybersecurity Workshop Programming Tasks Accomplished  An iOS app “Authenticator” was designed with authentication functionality based on fingerprint sensing and geofencing with Beacons  Since third party apps are not allowed to unlock the phone in iOS, successful authentication into the app displays some sensitive content  Display of sensitive information should be a useful example for user authentication using biometrics and geofencing

14. 2015 GenCyber Cybersecurity Workshop Authenticator - New iOS App  Supports three means of authentication:  geofencing using iBeacon when in range of iBeacon  fingerprint biometrics (TouchID) if outside of iBeacon range  password as fallback  Displays sensitive content if authentication is successful

15. 2015 GenCyber Cybersecurity Workshop Authenticator - iBeacons  Use CoreLocation framework to sense for iBeacons with specific UUID  If beacon is ranged the app bypasses the authentication screen and proceeds to the confidential content right away  If no beacon is ranged biometric authentication with Touch ID will be attempted next

16. Authenticator - Touch ID  fingerprints are evaluated using the method TouchIDevaluatePolicy —> sensitive content is unlocked  choice of Verizon statement or Terms (exemplary for sensitive content)

17. Authenticator - Document Access

18. Authenticator - Password Fallback  password prompt if beacons not in range (or user chose to not share location) and TouchID not available  set the UIA ApplicationExitsOnSus pend flag in the info.plist to true —> prevents the app from running in the background

19. 2015 GenCyber Cybersecurity Workshop Survey Results  The survey consisted of 10 questions, most multiple choice with a few fill- in data boxes.  Based on the results of the survey, the popular way of securing the mobile device seems to be with a password/PIN authentication with 54% of the participants.  As an alternate to password or swipe pattern entry, 73% of the participants stated in the survey that they would be most comfortable with interacting with the device with fingerprint or face recognition scan.  60% of the participants felt that fingerprint sensing is a more secure authentication than password/PIN authentication or other authentication mechanism.  Most people were unaware of NFC/ Geofencing based authentication mechanisms. Only 38% had similar apps installed on their phones  Majority of the people said they are uncomfortable having an app that requires location and bluetooth services turned on all the time  Overall, participants want a simple and easy way of unlocking their mobile device within minimal time, also giving them a secure feeling.

20. 2015 GenCyber Cybersecurity Workshop Future Work  A research study can be conducted for usability testing of designed apps and to test the comfort level of people with the current authentication mechanisms vs. the designed mechanism  Other physiological and behavioral sensors on smartphones and smartwatches can be used for user authentication.  Sensor data can be read using apps available from the Google Playstore or Apple AppStore or using a free, open source Software Development Kit for Android or iOS
