Location based authentication system

Abstract

A method for determining a fraud score associated with a monetary transaction facilitated using a payment card in a store is disclosed. The method comprises receiving data representative of an incoming payment transaction; analyzing a location of an owner of the payment card and a location of the store for determining a location rating; analyzing a location behavior profile (LBP) related to the payment card for determining a behavior rating, wherein the analysis is based in part on the incoming payment transaction; computing a transaction rating using the location rating and the behavior rating in combination with a first weight factor; analyzing historical payment transactions related to the payment card for determining a card rating; and computing the fraud-score using the transaction rating and the card rating in combination with a second weight factor.

1 . A computer-implemented method for determining a fraud score associated with a monetary transaction facilitated using a payment card in a store, the method comprising:
 receiving data representative of an incoming payment transaction;   analyzing a location of an owner of the payment card and a location of the store for determining a location rating;   analyzing a location behavior profile (LBP) related to the payment card for determining a behavior rating, wherein the analysis is based in part on the incoming payment transaction;   computing a transaction rating using the location rating and the behavior rating in combination with a first weight factor;   analyzing historical payment transactions related to the payment card for determining a card rating; and   computing the fraud-score using the transaction rating and the card rating in combination with a second weight factor.   
     
     
         2 . The method of  claim 1 , further comprising:
 authorizing said incoming payment transaction if said fraud-score is within a trust range.   
     
     
         3 . The method of  claim 1 , wherein the data representative of the incoming payment transaction includes at least one of: details of said payment card and the location of said store. 
     
     
         4 . The method of  claim 3 , further comprising:
 determining a cellular telephone number associated with the payment card; and   determining the location of a cellular telephone identified by the cellular telephone number so as to infer a geographic location of a purchaser.   
     
     
         5 . The method of  claim 2 , wherein said location rating indicates whether at least one: the cellular telephone is located in dose proximity to the store and the location of the purchaser with respect to the store. 
     
     
         6 . The method of  claim 2 , wherein said behavioral rating indicates whether a behavior pattern of said owner of said payment card deviates from said LBP. 
     
     
         7 . The method of  claim 2 , wherein said behavioral rating indicates whether a behavior pattern of said store deviates from said LBP. 
     
     
         8 . The method of  claim 1 , wherein said LBP includes at least behavior patterns of at least payment cards' owners and stores in respect to geographical regions and time periods. 
     
     
         9 . The method of  claim 2 , wherein said card rating indicates the number of previous suspected payment transactions recorded for said payment card. 
     
     
         10 . A non-transitory computer readable medium having stored thereon instructions for causing a computer to perform the method of  claim 1 . 
     
     
         11 . An authentication system for determining a fraud score associated with a monetary transaction facilitated using a payment card in a store, said authentication system comprising:
 a transaction processor for processing data representative of an incoming payment transaction for determining said fraud-score based on at least a location of an owner of said payment card and a location of a store;   a database for storing incoming payment transactions and fraud scores computed for incoming payment transactions; and   a display unit for displaying data representative of processed incoming payment transactions.   
     
     
         12 . The authentication system of  claim 11 , wherein said transaction processor authorizes said incoming payment transaction if said fraud-score is in a trust range. 
     
     
         13 . The authentication system of  claim 12 , wherein said authentication system is connected to a transaction server through a communication network to receive said data representative of said incoming payment transaction. 
     
     
         14 . The authentication system of  claim 12 , wherein said authentication system is further connected to a location based service (LBS) server to determine a geographic location of the cellular telephone associated the payment card. 
     
     
         15 . The authentication system of  claim 12 , wherein the transaction processor is adapted to determine said fraud score by:
 analyzing the geographic location of the owner of said payment card and a location of the store for determining a location rating;   analyzing a location behavior profile (LBP) related to said payment card for determining a behavior rating;   computing a transaction rating using the location rating and the behavior rating in combination with a first weight factor;   analyzing historical payment transactions related to said payment card for determining a card rating; and   computing the fraud-score using the transaction rating and the card rating in combination with a second weight factor.   
     
     
         16 . The authentication system of  claim 15 , wherein the data representative of the incoming payment transaction includes at least one of: details of said payment card and said location of said store. 
     
     
         17 . The authentication system of  claim 15 , wherein said location rating indicates whether a cellular telephone of an owner of the payment card is located in dose proximity to said store and the location of the purchaser with respect to the store. 
     
     
         18 . The authentication system of  claim 15 , wherein said behavioral rating indicates whether a behavior pattern of said owner of said payment card deviates from said LBP and whether a behavior pattern of said store deviates from said LBP. 
     
     
         19 . The authentication system of  claim 15 , wherein said LBP includes at least behavior patterns of at least payment cards owners and stores in respect to geographical regions and time periods. 
     
     
         20 . The authentication system of  claim 15 , wherein said card rating indicates the number of previous suspected payment transactions recorded for said payment card.
