<p>A system and method of completing a transaction over a network are provided. A personal electronic device (PED) receives transaction information; captures biometric information from a user of the PED; and uses the captured biometric information to identify if the user is an authorized user of the PED. If the captured biometric information identifies an authorized user of the PED, the PED performs the steps of: enabling a first one of a pair of cryptographic keys stored on the PED, said pair of cryptographic keys corresponding to the identified authorized user; generating a digital signature for the transaction using the enabled first key; generating an authenticated transaction request using the received transaction information, the authenticated transaction request comprising at least the received transaction information, the digital signature and information identifying the authorized user such as the second key of the pair of cryptographic keys; and transmitting the authenticated transaction request to a transaction approval center via the network. The transaction approval center uses the authenticated transaction request to complete the transaction; and the PED receives confirmation regarding the transaction from the transaction approval center.</p> |
