You can look at patterns of data usage, and behavior of identify and customer fraud very very easily. Lets suppose you certainly are a Credit Cards Company. That Saqeb is known by you as a customer offers certain behaviors. He will purchase airplane tickets, make hotel reservations, rents vehicles using his credit cards. When he goes purchasing, it is only on a weekend usually and only on certain shops that he goes shopping and buys sports activities action and goods clothing. And all of sudden you see completely different behaviors coming in then, such as credit card transactions in Karachi. Karachi by the real way has high stolen credit card price. And the patterns of shopping for behavior are stereos, and CDs and TVs i.e. electronic goods that are the things that individuals buy on stolen credit cards typically. You can notice and say “look, this is simply not resort or airplane reservations, this does not appear to be Saqeb”. It is not in the populous city where Saqeb lives or goes to very often. Although he was there a full week ago, so probably this is one way you may tell that whenever and where his credit card was stolen. And the buys were produced after he left the populous city. “big probability of fraud” hence. THEREFORE I can predict predicated on the behavior of the individuals, when things out from the typical routine happen. I QUICKLY can stop the fraud happening before it has spread actually. That’s the example in credit cards nevertheless, you can do a similar thing with telephone cards. I am certain you have used these phone cards. You punch in your quantity and you access telephone network. You discover people at railway or airports stations who make there living
by stealing calling card codes. They stay close to the phones at the fresh air port, they act like they are talking on the telephone, but they are looking over your shoulder when really you are punching in the code. And they memorize the code and proceed sell it on the then street to individuals who make long range phone calls to all or any their close friends in Brazil and Australia all these expensive locations. You can try the phoning patterns and say look “Saqeb makes regular phone calls to areas like say Rawalpindi and also to friends in Lahore” and most of sudden we see each one of these calls to Punjab or Sindh, meaning there is one thing wrong here.
