Anti-theft system for mobile phones developed
|
BRITISH scientists have developed a fraud detection system for mobile phones based on the call patterns of owners, New Scientist magazine said on Wednesday.
The new system, devised by the intelligent enterprise systems company SearchSpace, uses information on the numbers called, length of calls and when they are made to make behaviour profiles of users so special software can detect when something unusual occurs.
``It's like having a virtual software guardian assigned to each customer,'' SearchSpace's Jason Kingdon told the weekly magazine.
By using pattern recognition software, the system can pick up strange usage and send a text message to the mobile phone to confirm the pin number to verify their identify.
On a ``pay-as-you-go'' phone, users will be asked to increase their credit to confirm they are the rightful owners.
The phone will be cut off if the users do not comply.
``The software differs from existing fraud-detection systems because it analyzes behaviour dynamically. By not having fixed rules, it can recognize that users might make more calls than normal on New Year's Eve, for example, and let these through,'' the magazine said.
SearchSpace was spun off from the Intelligent Systems Laboratory at University College London.(SD-Agencies)
