BIOMETRIC PROTOTYPING

BIOMETRICS PROTOTYPING
Fingerprint Cellphone
The cellphone clearly illustrates the improved security and convenience that can be achieved using fingerprints. For cellphones,PINs (personal identification numbers) are used to prevent unauthorized persons from accessing the wireless network and incurring costs for the authorized user. Typically, a cellphone user must enter the PIN as soon as the device is switched on.For security reasons, only three attempts can be made to enter a PIN; if three incorrect PINs are entered, the SIM card is disabled. Should a cellphone be misplaced (a particularly critical situation if the cellphone is switched on), the service provider can disable the SIM card at the user s request.
Users of fingerprint phones are no longer plagued by such concerns. For them, security is literally at their fingertips.Fingerprint confirmation of each number dialed can easily be set up. This ensures that security cannot be breached even if a cellphone that is switched on falls into the wrong hands. What s more, the fingerprint phone recognizes not only a single authorized user; it can distinguish among several authorized persons, assigning personal phone books and accounts to each.
The electronics for the mobile phone shown above, together with the necessary firmware, has been developed in 1998 by our partner companies -> Triodata and -> Siemens PSE (Austria). It was the worldwide first fully functional fingerprint cellphone and has been presented on CeBIT 99 by the Siemens group Information & Communication Mobile on the basis of the SL 10 which was brand new at that time. Unfortunately, opposed to the beliefs at that time, fingerprint sensors will only be ready within a short time to be integrated into cellphones. For cost reasons, this will happen on the basis of swipe sensors.
Features
* Either PIN or fingerprint can be used to switch on and off
* Can be set up for fingerprint confirmation of numbers dialed
* The phone s owner can authorize other users at any time
* Number of fingerprints that can be stored: up to 60
* Number of users who can be authorized: up to 60
* Number of fingers that can be stored for each user: up to 10
* Number of prints that can be stored for each finger: up to 60
Fingerprint ID Card
For many e-commerce applications, the identity of the transaction partners must to ensured. Since passwords may be passed on to others, they unfortunately offer no help in determining who actually provided a (digital) signature.
The Fingerprint ID Card which has been shown at CeBIT 99 is a future-oriented solution that combines the biometric process of fingerprint verification with established encryption procedures. The result is a universal card which simplifies all business transactions requiring personal identification. Moreover, the Fingerprint ID card will reduce the number of items users need to carry with them every day; it can replace nearly everything from smartcards, driver s license, ID cards, and keys.
The Fingerprint ID card, a closed system, contains an integrated fingerprint sensor, a processing unit and a non-volatile memory for the fingerprint characteristics and data to be released on fingertip. Fingerprint characteristics can be stored exclusively via the sensor interface and can by no means be read out. In other words, the users unique and inalterable biometric data cannot be copied; nor can copied data be used. A challenge-and-response procedure which runs on an encryption processor on the card is used to inform the service provider that the card owner has beensuccessfully recognized.Because both the biometric fingerprint characteristics and the recognition algorithms are completely hidden in the card, any hackers are doomed to failure.
Another important feature of the fingerprint ID card is the option of having the card deactivated by a trust center, thereby increasing security in the event that the card is lost. On the other hand, a user may possess an unlimited number of cards.Cards can be deactivated thanks to the inseparable combination of a unique key pair for asymmetric encryption and the unique biometric characteristics of the card owner. While the biometric characteristics are inalterable, the key pair, and hence the combination, can be changed. The only condition is that a valid key pair be used (obtainable from the trust center).Otherwise, even the card owner cannot use the card.
Features
* No compromising of fingerprint characteristics possible
* No problem with vandalism, because the entire biometric unit is the property of the card owner
* Extremely high security against manipulation
* Universal applicability
* Two-pronged approach to protection against card loss
1. card does not function without the correct fingerprint
2. personal/public key pair can be centrally deactivated
* No data security problems as with central storage of fingerprint characteristics
* Inexpensive card readers without special security requirements
* Card dimensions: 85.6 mm x 54.0 mm x 3.3 mm
* Significantly more robust and durable than normal smart cards
Swipe-Sensor Devices
Swipe sensors are said to be less user friendly than plain sensors. With the aid of on ergonomic survey this conjecture could be disproved using these both devices which were equipped with sensors from Atmel. However, it could be shown that the design had a significant influence on the biometric performance. This investigation has been performed by employees of our partner -> SD&C.
Authentication Device
This prototype comprises a complete processor unit for capturing and processing fingerprints for test purposes. It can be controlled via a smartphone. It has been developed and realized together with the control software by our partner ->Siemens PSE in Austria.
