Abstract: A system and computer-implemented method for providing access to data of a first party including receiving information for identifying the first party, authenticating the first party using the received information for identifying the first party and generating a first read-only personal identification number (PIN). The first read-only PIN is associated with a first set of access rights for the data of the first party and provided to a second party. The first read-only PIN is stored with the first set of access rights in a computer database. A third party receives the first read-only PIN from the second party, authenticates the received first read-only PIN using the stored first read-only PIN and provides the second party with access to at least a portion of the data of the first party using the first set of access rights associated with the first read-only PIN if the received first read-only PIN is authenticated.

Abstract: A method for authenticating a check of a plurality of checks where the check was previously issued from a first party to a second party, including receiving first information from the first party, storing the first information in a file of a third party and receiving the check. The check has first party identifying information, a unique pseudorandom number of a pseudorandom sequence, and an amount. A status of activating the plurality of checks is determined. At least a portion of the first party identifying information included with the check, the unique pseudorandom number included with the check and the check amount included with the check are authenticated. The received check is authenticated if the first party, the unique pseudorandom number included with the check and the amount included with the check are authenticated and if the plurality of checks have been activated.

Abstract: A method for check clearing by a first entity where the check was previously issued from a first party to a second party. The first party has a first account with the first entity and the second party has a second account with a second entity. The first entity receives first information included with the check from the second party, including first party identifying information, a unique pseudorandom check number, and a check amount. The first entity authenticates at least a portion of the first information and receives second information from the second party, including at least the second account number and the second entity's routing transit number. The first entity transfers funds from the first account of the first party to the second account of the second party using at least a portion of the authenticated first information and the second information.

Abstract: A method for authenticating a financial transaction request includes receiving first information where the first information includes first party identifying information, and a unique pseudorandom number of a pseudorandom sequence included with a check from a plurality of checks. A status of activating the plurality of checks is determined using a portion of the first information, a stored activation code, and stored information first party identifying information. The stored first party identifying information is stored with the pseudorandom sequence. The first party is authenticated with the received and stored first party identifying information. The unique pseudorandom number is authenticated with the received first party identifying information, a portion of the stored first party identifying information and the stored sequence.

Abstract: A system and method for securing financial information in payment instruments including generating a pseudorandom number sequence, generating an activation code, including a unique pseudorandom number of the sequence with each payment instrument of a plurality of payment instruments and issuing the plurality of payment instruments with the activation code to a customer. The activation code is associated with customer identifying information and each unique pseudorandom number of the sequence included with each payment instrument of the plurality of payment instrument. The plurality of payment instruments is activated with the activation code. A received payment instrument of the plurality of payment instruments is authenticated if the customer and the unique pseudorandom number of the sequence included on the received payment instrument are authenticated and if the plurality of payment instruments are activated.
