Supporting safe and secure lifestyles...
Creating biometric security technology in which your body is your key

Security will be more critical than ever in the ubiquitous networking era, when financial services and administrative procedures will be easily handled anytime and anywhere. That is why we are leading the way in developing encryption and biometric authentication technology to protect privacy and confirm user identity. In addition to developing cutting-edge security technologies, we are also contributing to safer, more secure lifestyles by advancing our monozukuri and environmental technologies.

From cryptographic technology for computer and network safety to biometric technology and systems that confirm an individual's identity based on features of his or her own body, we are carrying out wide-ranging R&D in the area of information security.

Cryptography

In the area of cryptographic research, we are developing and accumulating basic technologies that confirm the secureness of cryptographic products and systems to protect privacy and to authenticate user identity. Based on mathematical theory and computer algebra, we are developing cutting-edge technologies to evaluate the security of cryptographic schemes against various attacks and also promptly responding to new vulnerability issues on cryptographic systems.

Biometric Authentication

In the field of biometric authentication, we are creating new innovations that will take the place of conventional ID and password systems —innovations like the world's first contactless palm vein pattern recognition technology and a compact, high-speed, highly accurate fingerprint authentication device for notebook PCs.

We are researching technologies to prevent information leakage from physical documents. We have already developed technology to embed invisible patterns which appear when the document is copied, as well as digital watermarking technology that invisibly imprints document source information. Embedding hidden information that can be detected even in repeated copies facilitates the tracing of information leaks.

We have also developed technology that can embed information in color images, including URLs and phone numbers that can be extracted with a camera without compromising image quality. By embedding this sort of information directly into color photos, design space can thus be used efficiently and effectively.

We are also developing System-in-Package technology, in which multiple LSI chips are mounted onto a single circuit board, and metal bump leveling technology for low-stress bonding of chip onto chip. And we are developing a filler material to protect bumps from stress damage caused by LSI chip overheating.

In the area of analytical technology, we are developing a means to measure structure, composition, and distortion of a thin film measuring just a few atomic layers. These technologies will contribute to the creation of smaller and more reliable LSI devices, magnetic heads and other cutting-edge devices.

Notice
Monozukuri is a Japanese term roughly translated as "the art of making things" and which describes an approach to development and manufacturing innovation that seeks maximum efficiency, productivity, and continuous improvement.

We are researching materials and solutions that take the environment into consideration. We were the first to commercially introduce notebook PC models featuring housings made with an environmentally friendly bio-based plastic that requires less oil to produce and which exhibits good structural strength and fire resistance characteristics. In addition, we are continuing research in photocatalytic technology for dissolving dirt and stains using UV rays. We have also developed methods to evaluate the extent to which deploying particular IT solutions can reduce the burden on the environment.

Bioinformatics are computer technologies used to create databases and to obtain, accumulate, systematize, analyze and visualize the data for biological, medical, behavioral or health related studies. For these purposes, we have been conducting research and development in technologies such as a massive parallel simulation server called "BioServer" for pharmaceutical development, microinjection technology that injects gene or chemical compound into cells, chemical calculation software, and gene analysis software.
