## 【Abstract】

T.Harada

Prof.Umezaki realized that the high level noise elimination technology used in speech recognition could also be the key ingredient for identifying fingerprint patterns. The cepstrum analysis method for speech recognition system was applied to a two-dimensional fingerprint image.

Two companies, Chuo Spring Co., Ltd. and DDS Inc., used this technology transfer of Prof. Umezaki to develop and market a mobile device fingerprint verification system for entering and leaving and other fingerprint verification products.

## 【Summary of the technology transfer】Technological Impact

The spectrum analysis method is more effective than conventional fingerprint authentication in comparison with "Minutia method" or "Subtraction method of two Image patterns". It can cope with influence from blurs, and there are extremely few problems with fingerprint registration.

## ●Special Features of the Collaboration

DDS Inc., was listed on the Tokyo Stock Exchange [ MOTHERS ] on November 28, 2005 for its achievements of sales results of a fingerprint verification device as their main product. In addition, it had sales of 24% in the fingerprint authentication market (a market share according to amount ) in 2006 and became the industry leader (Fuji Chimera Research Institute, Inc.).

## Market Impact

It used in the Nagoya City Government Offices (about 9,000 devices), the Saga Prefecture Offices (about 5,000), the Tokyo Kita Ward Offices (about 2,000), and the NTT West Co., (about 50,000). The Board of Audit of Japan, the Matsuzaka City Offices, the Ooi Nuclear Power Plant, and others. It is in general use in many government, state, and private enterprise offices. They provide security against such things as personal data leaks.

## ●Social Impact

An industry-university cooperation results in the prompt development and marketing of innovations. The university supplies technical guidance, manufacturing companies develop and produce the device and the major companies handle sales and maintenance of the product-a three-part system.

## Project Background

The two companies groped for business development to a new field (Chuo Spring Co., Ltd.) and evolving from developing on contract into company's self-development (DDS Inc.). Prof. Umezaki initiated technology transfer negotiations and they decided participation in planning to biometrics business.

## Funding History

1. Aichi Regional Science Program (Results of research developing type), “A study of a semiconductor for fingerprint authentication algorithm” (2000-2001).

2. Grant-in-aid for Scientific Research-subsidy based C (2), "A development of a non-touch type fingerprint verification sensor and its verification algorithm" (2006-2008).
