In an increasingly globalised and ubiquitous information society, security has become a paramount concern in today’s world. Hitachi addresses these concerns with Hitachi VeinID – a state-of-the-art, user-friendly Finger Vein Biometric technology that uses the unique vein patterns of a finger to authenticate an individual’s identity.

Access Control can now be easily implemented with Hitachi VeinID products. Protect corporate assets and information leakage, prevent spoofing and other criminal impersonation in areas such as financial (cash or credit card) transactions, entry into important facilities and offices, access to IT equipment and resources and many other applications with Hitachi’s patented Finger Vein Biometric Authentication technology.

Finger Vein Authentication System – Basic Principle

The basic principle of the Finger Vein authentication system is shown below. Near-infra rays generated from a bank of LEDs (Light Emitting Diodes) permeate the finger and are absorbed by the hemoglobin in the blood. The areas in which the rays are absorbed (i.e. veins) thus appear as dark areas in an image taken by a CCD/CMOS camera located on the opposite side of the finger. Image processing can then construct a finger vein pattern from the camera image. This pattern is then compressed and digitised so that it can be registered as a template of a person’s biometric authentication data.
