Abstract
A method, system and computer program product for private information exchange in smart card commerce is disclosed. The method includes, in response to determining that an item of biometric data received on a biometric reader corresponds to an authorized user, unlocking a communication channel on a communication port, exchanging public keys between the user and authorized point of sale, receiving an information request from an external point of sale machine across the communication channel, decrypting an information request and parsing a data token. In response to determining that private data has been requested in the information request, a user is prompted for authorization to release the private information, and private information exchange in smart card commerce is performed by, in response to the user pressing a yes button on the smart card, placing an encrypted copy of the private data in the public area of the smart card for transmission across the communication channel to the external point of sale machine.
