Abstract

Systems, methods, and computer-readable media are provided for processing and settling financial transactions. An example method comprises receiving a transaction from an originator. The transaction comprises information associated with an identification of an initiating user or the account. The method comprises determining the actual account number, transmitting a financial services transaction request comprising the actual account number to a financial institution, receiving a response, and transmitting a response back to the originator. Another method comprises receiving, from a user device, a request to associate a financial account with a user account. The method comprises generating and sending an association message to a payment network and receiving a key associated with the financial account for use in initiating financial transactions. Another method comprises utilizing such a key to generate and process a transaction request. Other systems, methods, and media are also provided.

First claim

What is claimed is:

1. A computer system, comprising:
a processor; and
a memory comprising instructions that, when executed by the processor, cause the processor to perform operations comprising:
receiving a transaction request from a second computer system associated with a transaction origination point, wherein the second computer system receives the transaction request from a first computer system associated with a merchant, wherein the transaction request is associated with the initiating user and an account,
generating a service provider key associated with the second computer system, wherein the service provider key is stored in a security module, wherein the service provider key is encrypted using a master key associated with the security module, wherein the transaction request comprises a cryptogram based on an account key, wherein the account key is generated by encrypting account information using an instrument key, wherein the instrument key is generated by encrypting institution information using a first key associated with the first computer system and a second key associated with a financial institution;
deriving the instrument key and the account key using the service provider key;
decrypting the cryptogram using the identified account key;
receiving a transaction counter from the second computer system;
validating that the transaction request was sent from the second computer system using the instrument key;
determining, by searching a database, an account identifier associated with an account number of the account;
transmitting a transaction comprising the determined account identifier to the financial institution, including an identifier associated with the initiating user;
receiving, from the financial institution, a response to the transaction; and
transmitting a response to the transaction request to the second computer system.

2. The system of claim 1 , wherein:
the transaction request comprises identification of the initiating user or the account, and
the identification comprises a substitute account identifier different from the account identifier and an indicator value, and
the account identifier is determined by using the substitute account identifier to search a database for the account identifier and a Routing Transit Number associated with the account.

3. The system of claim 1 , wherein the transaction request further comprises information associated with an identification of the initiating user or the account.

4. The system of claim 3 , wherein the account identifier is determined by searching the database using the identification of the initiating user or the account.

5. The system of claim 1 , further comprising generating the account key in response to a request from the second computer system.

6. The system of claim 5 , wherein the operations further comprise:
forwarding at least one piece of information to the second computer system;
receiving an account validation response message; and
determining, based on the account validation response message, whether to generate the institution key and the account key.

7. The system of claim 1 , wherein the operations further comprise comparing a previously received transaction counter with the transaction counter.

8. The system of claim 1 , wherein the operations further comprise:
determining, based on the transaction request received from the system, a net settlement amount applicable to at least two settlement accounts; and
creating at least two entries in an Automated Clearing House file that indicates a debit and credit to the at least two accounts reflecting to the net settlement amounts.

9. The system of claim 1 , wherein the first computer system is one of a financial institution, an Electronic Funds Transfer network, a merchant, a merchant processor, a remittance processor, a transaction origination point, or a mobile wallet provider.

10. A method comprising steps performed by a processor, the steps comprising:
receiving a transaction request from a second computer system associated with a transaction origination point, wherein the second computer system receives the transaction request from a first computer system associated with merchant, wherein the transaction request is associated with the initiating user and an account,
generating a service provider key associated with the second computer system, wherein the service provider key is stored in a security module, wherein the service provider key is encrypted using a master key associated with the security module, wherein the transaction request comprises a cryptogram based on an account key, wherein the account key is generated by encrypting account information using an instrument key, wherein the instrument key is generated by encrypting institution information using a first key associated with the first computer system and a second key associated with a financial institution;
deriving the instrument key and the account key using the service provider key;
decrypting the cryptogram using the identified account key;
receiving a transaction counter from the second computer system;
validating that the transaction request was sent from the second computer system using the instrument key;
transmitting a transaction comprising the determined account identifier to the second computer system, including an identifier associated with the initiating user;
receiving, from the financial institution, a response to the transaction; and
transmitting a response to the transaction request to the second computer system.

11. A system, comprising:
a processor; and
a memory comprising instructions that, when executed by the processor, cause the processor to perform operations comprising:
generating a service provider key associated with a transaction origination point, wherein the service provider key is stored in a security module, wherein the service provider key is encrypted using a master key associated with the security module,
generating an instrument key, wherein the instrument key is based on a key associated with the financial institution that holds the financial account, and the key associated with the financial institution is based on an account key that is generated using the service provider key;

sending the instrument key to the transaction origination point;
receiving a transaction request from the transaction origination point, comprising a request to perform a transaction on behalf of a user, the transaction request not including an account number, the transaction request comprising a cryptogram encrypted using the instrument key;
receiving a transaction counter from the transaction origination point;
validating that the transaction request was sent from the transaction origination point using the institution key;
generating a transaction message including a cryptogram generated by encrypting information associated with the transaction using the instrument key;
sending the financial services transaction message to the financial institution; and
receiving a response from the financial institution.

12. The system of claim 11 , wherein the transaction request further comprises information associated with an identification of the user or the account.

13. The system of claim 11 , wherein the information associated with the transaction comprises at least one of at least one of a code representing the currency for the transaction, a date associated with the transaction, the amount of the transaction, a country code, a transaction counter, or a random number.

14. The system of claim 11 , wherein:
the key associated with the financial account is generated by e
