Abstract

A system for implementing personal identification number (PIN)-based data transfer activities includes a host system and a PIN generator application and encryption engine executing on the host system. The PIN generator application and the encryption engine generate an instance of a PIN by the PIN generator application in response to a request by a holder of an instrument to create the PIN. Generation of the instance of the PIN includes receiving an instrument identifier and a data value from the holder of the instrument, retrieving a transfer system key and a seed value associated with the instrument from an account record associated with the instrument identifier, and encrypting the instrument identifier, the data value, the transfer system key, and the seed value to form the instance of the PIN. The instance of the PIN is provided to the holder of the instrument. The data value is encoded on the instrument.

Dependent claims

A system for implementing personal identification number (PIN)-based data transfer activities, comprising:

a host system;
and
a PIN generator application and encryption engine executing on the host system, the PIN generator application and the encryption engine implementing a method, comprising:
generating an instance of a PIN by the PIN generator application in response to a request by a holder of an instrument to create the PIN, the PIN used in transferring a data value to the instrument, the data value including at least one of a value of products or services, and a function to be performed via the instrument, the generating comprising:
receiving an instrument identifier and the data value from the holder of the instrument;
retrieving a transfer system key and a seed value associated with the instrument from an account record associated with the instrument identifier;
and
encrypting the instrument identifier, the data value, the transfer system key, and the seed value to form the instance of the PIN;
and
providing the instance of the PIN to the holder of the instrument;
wherein the data value is encoded on the instrument in response to:
providing the instrument to a transfer system associated with the transfer system key;
providing the PIN to the transfer system by the holder of the instrument;
decrypting the PIN;
and validating the instrument identifier, the transfer system key, and the seed value.

9 more elements

A computer program product for implementing personal identification number (PIN)-based data transfer activities, the computer program product including instructions for causing a computer to implement a method, comprising:

generating an instance of a PIN by a PIN generator in response to a request by a holder of an instrument to create the PIN, the PIN used in transferring a data value to the instrument, the data value including at least one of a value of products or services, and a function to be performed via the instrument, the generating comprising:
receiving an instrument identifier and the data value from a holder of the instrument;
retrieving a transfer system key and a seed value associated with the instrument from an account record associated with the instrument identifier;
and
encrypting the instrument identifier, the data value, the transfer system key, and the seed value to form the instance of the PIN;
and
providing the instance of the PIN to the holder of the instrument;
wherein the data value is encoded on the instrument in response to:
providing the instrument to a transfer system associated with the transfer system key;
providing the PIN to the transfer system by the holder of the instrument;
decrypting the PIN;
and validating the instrument identifier, the transfer system key, and the seed value.
