Speed ​​up the verification process

Speed ​​up the verification process,  new technology by extracting the feature code from the image of the palm vein

August 5, for the first time in the world in the development of technology that can extract the feature code of multiple of 2048 bits from the image of the palm vein, you can use the biometric information in different services, you can speed up the verification process Fujitsu Laboratories today announced that it has succeeded. I aim to commercialize the 2015 fiscal year.

Reads the features such as the shape of the vein from the image of the palm vein, new technologies have been developed to be used for authentication by converting a 2048 bit "feature codes". For this purpose, we have developed conversion technology and image correction to eliminate the need for alignment during the registration image of the palm vein matching.

Re feature code new immediately when you can generate a feature code that different if you change the conditions to be converted to a feature code from the vein image, you can use the feature different code for each service, information on the feature code had a leakage or theft is that you can or you can enroll. Amount of information of feature code is less about one-tenth of the information of the vein image to be used for palm vein authentication.


Examine the differences between the registered codes to identify the person, if the threshold value or less in the authentication process by the feature code. Since it does not require authentication processing prior to match a pattern against the reference image, the processing time that is significantly reduced with 1 microsecond from a few milliseconds conventional.
 

A high level of safety in terms of using the information seen only by have the "biometrics, but Nizaki table competent researcher of Fujitsu Laboratories Software Engineering Laboratory Secure Computing Lab that conference, several from the risk of information leakage It is described the case that there is resistance to be used in service than a few. to be "want to improve the convenience of biometric authentication by converting a feature code.

According to Nizaki said, in addition to the pattern of feature codes that can be generated is 100 square scale of 2, can be applied to a system that requires authentication processing large, since the small amount of data, recording the feature code to the IC card that it is also possible to use for authentication with.

(Percentage of recognization of person by mistake others)

false acceptance rate according to the features code is one level of 100 000, but (percentage to recognize the others the wrong person) false rejection rate that is higher than the current product at this time. It is the goal of practical application of the 2015 fiscal year, and work and improve the authentication accuracy by improving, such as feature code extraction technology and image processing technology, such as the design of biometric authentication infrastructure which adopted the new technology the company.

It has been described as "want to improve the usability of the biometric authentication by that.
