System and method for securing rf transactions using a radio frequency identification device including a random number generator

Abstract

A system and method for securing a Radio Frequency (RF) transaction using a RF identification device (RFID) transaction device is provided. The method includes a RFID transaction device including a random number generator for generating a random number. The random number may be used by an account issuer to verify the validity of a RFID transaction device or RFID reader communicating on the RF transactions network. The authorizing agent may receive the random number and compare the random number to a device validating code.

1 . A system comprising:
 a tangible, non-transitory memory communicating with a processor for securing a transaction,   the tangible, non-transitory memory having instructions stored thereon that, in response to execution by the processor, cause the processor to perform operations comprising:
 receiving, by the processor, a transaction device random number; 
 looking up, by the processor using the transaction device random number, a previously stored decryption key; and 
 decrypting, by the processor using the previously stored decryption key, at least one of a transaction device identifier and a transaction device authentication tag. 
   
     
     
         2 . The system of  claim 1 , wherein the receiving the transaction device random number is from an RFID transaction device. 
     
     
         3 . The system of  claim 1 , wherein the transaction is a radio frequency (RF) transaction. 
     
     
         4 . The system of  claim 1 , wherein the transaction device identifier is different from the transaction device authentication tag. 
     
     
         5 . The system of  claim 1 , further comprising transmitting to a reader, both the transaction device identifier and the transaction device authentication tag for validation, wherein the validation is based at least in part on both the transaction device identifier and the transaction device authentication tag. 
     
     
         6 . The system of  claim 1 , wherein the transaction device random number is converted to a validating code and used to validate a transaction device. 
     
     
         7 . The system of  claim 1 , wherein a new transaction device random number is generated for each transaction. 
     
     
         8 . The system of  claim 1 , further comprising a random number generator for producing a reader random number. 
     
     
         9 . The system of  claim 1 , wherein a reader is operable to provide the transaction device random number to a point of sale device (POS). 
     
     
         10 . The system of  claim 1 , wherein a reader is operable to provide the transaction device random number to a POS, and wherein the POS is configured to provide the transaction device random number to the account authorizing agent system. 
     
     
         11 . The system of  claim 1 , wherein a reader is operable to provide the transaction device identifier to a point of sale device (POS). 
     
     
         12 . The system of  claim 1 , wherein at least one of the transaction device identifier and the transaction device random number is provided to a reader in track 1/track 2 International Standards Setting Organization format. 
     
     
         13 . The system of  claim 1 , wherein at least one of the transaction device identifier and the transaction device random number is provided to a reader in a POS pre-defined format. 
     
     
         14 . The system of  claim 1 , wherein an authorizing agent system is configured to validate the transaction device identifier in accordance with the transaction device random number. 
     
     
         15 . The system of  claim 1 , wherein a POS is configured to provide at least one of the transaction device random number, transaction device identifier, and reader RFID reader random number to an account authorizing agent system. 
     
     
         16 . The system of  claim 1 , wherein a reader is operable to provide at least one of the transaction device random number, the transaction device identifier, and the random number to a merchant POS. 
     
     
         17 . The system of  claim 1 , wherein an authorizing agent system is configured to validate at least one of a transaction device and a reader, in accordance with the at least one of the transaction device random number, the transaction device identifier, and the transaction device random number. 
     
     
         18 . An article of manufacture including a non-transitory, tangible computer readable medium having instructions stored thereon that, in response to execution by a computer-based system for securing a transaction, cause the computer-based system to perform operations comprising:
 receiving, by the computer-based system, a transaction device random number;   looking up, by the computer-based system using the transaction device random number, a previously stored decryption key; and   decrypting, by the computer-based system using the previously stored decryption key, at least one of a transaction device identifier and a transaction device authentication tag.   
     
     
         19 . A method comprising:
 receiving, by a computer-based system for securing a transaction, a transaction device random number;   looking up, by the computer-based system using the transaction device random number, a previously stored decryption key; and   decrypting, by the computer-based system using the previously stored decryption key, at least one of a transaction device identifier and a transaction device authentication tag.
