  1. Privacy analysis of user association log in an enterprise wireless network Keren Tan

  2. Background • To protect privacy, we sanitize network trace before sharing them • General sanitization mainly focus on randomizing or truncating explicit user identity information randomize 345356 129.170.212.88 129.170.212.* truncate

  3. Motivation • Besides those explicit identity information in each log entry, much information that can be linked to a specific user (or a small subset of users) is also implicitly contained in collected traces.

  4. Which one is Snoopy? Person 1 Gym, 100min Bake, 50min Sudikoff, 45min Sanitized Person 2 Gym, 55min Bake, 50min Sudikoff, 25min Bake, 30min Sudikoff, 55min Bake, 60min Gym, 80min NP, 10min Person 1 looks like more similar than Person 2?

  5. Challenges Duration 3 months Dataset size > 50GB Scalability! Number of users > 22000 Number of APs> 1300
