Method and system to verify a transaction

Abstract

A method and system to verify a transaction are described. The system may include an escrow module to receive funds from a client, a communication module to receive a request from the provider to redeem a provider set of tokens, and a redemption module to selectively redeem the provider set of tokens. The funds received by the escrow module are associated with a transaction between the client and a provider. The redemption module may be configured to examine the provider set of tokens and selectively redeem the provider set of tokens based on the results of the examination.

1 . A system comprising:
 an escrow module to receive funds from a client, the funds being associated with a transaction between the client and a provider;   a communication module to receive a request from the provider to redeem a provider set of tokens; and   a redemption module to:
 examine the provider set of tokens, and 
 selectively redeem the provider set of tokens, based on the results of the examination. 
   
     
     
         2 . The system of  claim 1 , further comprising:
 a token generator associated with a third party to issue a client set of tokens to the client;   a token verification list generator associated with the third party to issue a verification set of tokens to a provider, the verification set of tokens suitable for determining that a reference set of tokens is the client set of tokens.   
     
     
         3 . The system of  claim 2 , wherein the redemption module is to examine the provider set of tokens and the client set of tokens to determine whether the provider set of tokens matches the client set of tokens. 
     
     
         4 . The system of  claim 2 , wherein the redemption module is to redeem the provider set of tokens in response to determining that the provider set of tokens matches the client set of tokens. 
     
     
         5 . The system of  claim 1 , wherein the redemption module is to deny the request from the provider to redeem the provider set of tokens in response to determining that the provider set of tokens does not match the client set of tokens. 
     
     
         6 . The system of  claim 2 , wherein the client set of tokens is a subset of the verification set of tokens. 
     
     
         7 . The system of  claim 1 , wherein the redemption module is to process the request based on an acceptance policy. 
     
     
         8 . The system of  claim 7 , wherein the acceptance policy includes denying the request if the request is made after a predetermined period of time subsequent to the time of issuing of the client set of tokens. 
     
     
         9 . The system of  claim 1 , wherein the set of client tokens includes one or more numerical identifiers. 
     
     
         10 . The system of  claim 1 , wherein the redemption module is to invalidate the client set of tokens in response to the redeeming of the provider set of tokens. 
     
     
         11 . A method comprising:
 receiving funds from a client, the funds being associated with a transaction between the client and a provider;   receiving a request from the provider to redeem a provider set of tokens;   examining the provider set of tokens; and   selectively redeeming the provider set of tokens based on the results of the examining.   
     
     
         12 . The method of  claim 11 , further comprising:
 issuing, from a third party, a client set of tokens to the client; and   issuing, from the third party, a verification set of tokens to a provider.   
     
     
         13 . The method of  claim 12 , wherein the satisfying of the request includes releasing the funds associated with the transaction between the client and the provider to the provider. 
     
     
         14 . The method of  claim 12 , wherein the client set of tokens is a subset of the verification set of tokens. 
     
     
         15 . The method of  claim 12 , wherein the selectively satisfying of the request includes redeeming the provider tokens if the provider set of tokens matches the client set of tokens. 
     
     
         16 . The method of  claim 12 , wherein the selectively satisfying of the request includes denying the request if the provider set of tokens does not match the client set of tokens. 
     
     
         17 . The method of  claim 12 , wherein selectively satisfying of the request includes denying the request if the request is made after passage of a predetermined period of time following the time of issuance of the client set of tokens. 
     
     
         18 . The method of  claim 12 , wherein the client set of tokens includes one or more numerical identifiers. 
     
     
         19 . The method of  claim 12 , further including invalidating the client set of tokens in response to the redeeming of the provider set of tokens. 
     
     
         20 . A machine-readable storage medium having instruction data to cause a machine to:
 receive funds from a client, the funds being associated with a transaction between the client and a provider;   receive a request from the provider to redeem a provider set of tokens;   examine the provider set of tokens; and   selectively redeem the provider set of tokens, based on the results of the examination.
