Yoshimura Lab
Machine-translated · View original
A lab that uses light to process fingerprints and images, building secure and reliable information communication.

AboutAbout the lab
Verifying identity with light.
Yoshimura Lab's main research themes are biometrics and optical information processing systems.
Information communication that connects the various elements that make up a city is important, and to ensure its reliability and security, the lab studies biometric authentication and information security technologies.
Focusing on fingerprints, the most widely used biometric today, the lab develops methods and devices that use laser light and lenses to verify identity quickly and with high accuracy.
The lab also works on research toward building secure and reliable information communication environments, such as the encryption of image information.
Key terms
- Biometrics
- Technology that verifies identity using bodily characteristics that differ from person to person, such as fingerprints, finger veins, and irises
- Encryption
- Converting information into an unreadable form by a set procedure so that only a person holding the key can restore it
- Iris
- The colored membrane surrounding the pupil, whose pattern of folds differs from person to person

This is technology that verifies identity using physical characteristics that differ from person to person, such as fingerprints, finger veins, and irises. Focusing on fingerprints, the most widely used today, the lab studies methods and devices that use laser light and lenses to authenticate faster and with higher accuracy.
*Illustrative imageEncryption and Processing of Image Information
Encryption is essential for the reliability and security of information services and for the protection of personal data. The lab studies image encryption that is simple, fast, and highly confidential, as an alternative to current encryption methods.
