Presentation • Motivation • Experimental environment • Entry events • Architecture • Modules • Integration • Verification • Discussion
Motivation (security project) • Terrorist attacks – bypass sensors • Malitious employee – drunk, angry ... intercept unusual events based on intelligent experience • 2 people entering, one registered • employee “afraid”
Experimental environment Camera Fingerprint reader Card reader Door sensor
Entry event • Card identification • Fingerprint verification • Door opens • Door closes • Unusual behavior • ̴ 10 additional scenarios in advance Bomb attack – only door opens A terrorist steals a card and a finger
Access sensors and Time&Space software Fingerprint reader Camera Door sensor Card reader Videos Time&Space controller Camera module TCP/IP TCP/IP Intelligent system ODBC
Module 1: Expert system • A set of̴ 10 predefined types of rules • Verifies if the events are “legal” • None of user behavior learning is used • Examples of generic rules: • alarm / warning if event between time1 and time2 • alarm / warning if more than N events in time • alarm / warning if no exit before time • alarm / warning if no exit in time
Module 2: Micro learning • Learns user behavior on micro level – micro timing • Algorithm: Local outlier factor • Classification and explanation
Module 3: Macro learning • Learns user behavior on macro level – macro timing / classification and explanation
Module 3: Vision • Learns user behavior from video
Integration Regular event Alarm event Main thread Expert system Micro learning Macro learning Camera Displaying final result
Measurements • Our tests with our employees • Our “simulated” tests with our employees • Joint tests by security experts • perform several of them
“Simulated” Measurements • Tested modules: Expert rules, micro learning and macro learning • Create regular accesses: Five people, each 40 learn and 10 test accesses – • Create irregular accesses: Fake-identity experiment – generate entries with identification card of another person
Measurements - results Statistic for regular accesses Statistic for irregular accesses Ok – 88% of regular accesses Alarm – 69% of irregular accesses
Conclusion • Designed and tested an original ambient-inteligence system for entry control based on user behavior • It integrates arbitrary (currently four) independent modules and sensors • Significant increase in security • Patent pending, real-life application
