Fujitsu (Link) (June 1, 2011)
Fujitsu Laboratories Ltd. today announced the development of the world’s first biometric authentication technology that combines data on palm vein patterns with fingerprint data from three fingers. By employing both palm vein pattern and fingerprint data, the technology enables the rapid identification of a given individual out of data from a million people, processing the match within two seconds.
This technology makes it possible to construct biometric authentication systems that do not require ID cards and that can be tailor-made to fit different sized groups, from small-scale room access control to large-scale social platform systems. Moreover, the technology can be easily deployed by simply adding palm vein authentication to the fingerprint authentication systems that are already in widespread use.
Biometric authentication technology is becoming increasingly ubiquitous as a means to prevent corporate data breaches and identity fraud at financial institutions. This includes palm vein authentication based on a technology pioneered by Fujitsu Laboratories, now widely employed around the world for its highly precise authentication in applications ranging from ID confirmation for ATM users at financial institutions, to corporate PC access management and room access control systems. In addition, rapid fingerprint authentication processing is becoming popular as an easy and reliable personal log-in authentication method built into PCs and mobile phones.
The convenience offered by simply using one’s body for authentication - biometrics eliminates the need to carry IC cards - is expected to accelerate the spread of biometrics even further. As the key to realize greater acceptance, the focus has turned to technologies that can recognize with superior speed and precision a given individual out of a million or hundred million people in applications for large corporations and governments.
To determine whether specific biometric data of a given individual recorded in an IC card is a match or not (one-to-one matching), such as is the case for authentication systems used in financial institutions, current authentication methods using just one type of biometric data are sufficient. However, when attempting to distinguish and identify a given person from a group of many people (one-to-many matching), precision becomes problematic if the pool of people is as large as a million or ten million people. This results in cases in which it is impossible to clearly distinguish among potential matches using just one type of biometric data. For one-to-many matching, because authentication requires sifting through all records registered in a system, the level of precision required to authenticate one person out of a pool of one million is a million times the level of precision required for one-to-one matching.
One solution proposed for addressing this problem is to build a robust authentication system that combines multiple biometric authentication methods. Separately capturing the biometric data needed for each method, however, diminishes the convenience of this approach. For example, if palm vein authentication were combined with iris pattern authentication, both the palm and iris would each need to be separately scanned, compromising simplicity. This necessitated a technology that could easily combine more than one type of biometric data.
Moreover, in order to authenticate one person out of a million, because processing entails sifting through all one million records, authentication processing could take over twenty minutes using conventional technologies. Accordingly, also needed was technology that would dramatically reduce required processing time.
Newly Developed Technology
Fujitsu Laboratories has developed a system that can identify a given person out of a pool of a million people, delivering one-to-one million matching. This was accomplished by combining fingerprint authentication, already in wide use and easily performed at high speed, with palm vein authentication, which has superior accuracy and is extraordinarily difficult to falsify, making it highly secure against fraud. The system developed with this technology uses palm vein and fingerprint data from three fingers. Capturing both finger and palm vein data in a single scan, the identity of a given person from a pool of a million can be authenticated within two seconds through parallel processing on multiple servers. †
