Deploying Solutions to Identify People & Their Behaviours

VEIN RECOGNITION

How does it Work?

Vein recognition systems work on the fact that every one has distinct vein patterns. Vein recognition systems record subcutaneous Infra Red (IR) absorption patterns to produce unique and private identification templates for users. The technology works as a vascular "bar" code reader for people.

Veins and other subcutaneous features present large, robust, stable and largely hidden patterns. Subcutaneous features can be conveniently imaged within the wrist, palm, and dorsal surfaces of the hand and further used for identification or verification. 

Vein pattern IR grey-scale images are binarised, compressed and stored within a relational database of 2D vein images. Subjects are verified against a reference template. There are different types of vein recognition technology, which include finger vein, wrist vein, palm, and backhand vein recognition. The underlying concept of scanning remains the same with each of these techniques.

How is it being Used?

The technology has extensive applications can be applied to small personal biometric systems e.g. Biowatches and Biokeys and to generic biometric applications including intelligent door handles, door locks etc".  The robustness of the system can be measured from the fact that its current applications include cash machines and ATMs. Some other applications include:

• Computer Log Ins
• POS Authentication
• Time Attendance Applications
• Physical Access Control

Advantages of using Vein Recognition

• The vein patterns are unique to each individual and apart from size; the pattern does not change over time.
• A contact free technology involving no physical contact with the hardware.
• Extremely difficult to steal/misuse as veins are not visible to naked eye.
• Not contact models are more hygienic than all forms of contact biometrics.
