7. Phone Software Typical Use-case: 1.Enable Bluetooth on your phone, connect to BLUETAG wireless network 2.Login 3.Enter tag visual ID, connect to tag 4.Click “Buy” 5.Verify tag unlocked

8. System Security Protection of sensitive information –Unlock codes –User account information Potential vulnerabilities –Database attack –Bluetooth monitoring –WiFi monitoring –Physical abuse

9. Bluetooth Security Existing Measures Frequency hopping (can be cracked) Encryption (many weaknesses) Bluetag Additions Dynamic unlock codes Unlock code mapping

10. Bluetooth Security

11. WiFi Security Database RSA encrypted at 512 bits The number of possible keys : 2 512 = 1.34E154 ; With a device that could check 1E18 keys per second, It will require 4.25E128 years to try all keys; Where age of universe = 1.3E10 years

12. Cost Analysis

14. Meeting Project Goals Full Bluetag system delivered Highly secure Cost effective Lightweight, handheld tag Readily deployable
