Abstract: An anonymous secure messaging method, system and computer program product for implementation over a wireless connection. The invention allows the securely exchange of information between a security token enabled computer system and an intelligent remote device having an operatively coupled security token thereto over the wireless connection. The invention establishes an anonymous secure messaging channel between the security token and the security token enabled computer system, which allows the intelligent remote device to emulate a locally connected security token peripheral device without requiring a physical connection. A dedicated wireless communications channel is incorporated to prevent several concurrent wireless connections from being established with the security token and potentially compromising the security of the information being sent on concurrent wireless connections.

Abstract: A method, system and computer program product for improving error discrimination in biometric authentication systems. The error discrimination is set to a predetermined security policy. A plurality of biometric samples are provided and authenticated by a computer system in conjunction with a security token. An alternate embodiment allows inputting of the plurality of biometric samples in a predetermined sequence. The predetermined input sequence is maintained as an authentication secret which may be used to further reduce the authentication transaction error rate.

Abstract: Smartcards are gaining acceptance as a secure medium for storing information, typically of a personal and confidential nature. Unfortunately, the process of storing information to the smartcard is a time consuming task, often taking much longer than to read the same amount of information from the card. The non-volatile memory within the smartcard is typically of the FLASH type and does not facilitate fast writing a fast writing process thereto. In order to speed up this process, a comparative writing algorithm is utilized which only writes changed data to the smartcard memory, thus eliminating the need for storing duplicate information.

Abstract: A portable biometric device enables a designated person to unlock any one portal exclusive of other portals of a secure entity and or a secure service by choosing which of their personal biometric characteristics is presented to the portable biometric device. The portable biometric device includes a biometric sensor such that a biometric characteristic of a person for example a finger pattern is read dependent upon the person presenting the biometric characteristic to the biometric sensor. The reading is encoded in order for a processor to determine if the biometric characteristic has been predesignated for access via a predesignated one of the plurality of portals. If so, the processor selects an appropriate authorization code which is communicated by wireless transmission for unlocking the predesignated one of the portals, to the exclusion of any other of the portals. In an alternate example the processor is a central controller remote from the biometric device.
