Overview
The technologies developed by id3 Semiconductors are the result of many years of Research and Development as well as a strong experience. They mainly targe embedded applications and comply with current standards.
1- Biometrics:
id3 Semiconductors' biometrics technologies are designed for high performance fingerprint recognition solutions, combining accuracy and interoperability.
Fingerprint recognition
Fingerprint is the most widely used biometric identification mean: due to its easy capture, its uniqueness and its permanence, it is the best choice to design both reliable and a robust identification system. Indeed, each person (even an real twins) owns unique and permanent fingerprints ,that only intradermal injuries can damage (burn for example).
Fingerprint patterns are actually characterized by the upper part of the skin waves; called the ridges and spaces between them; called the valleys. In each verification or identification process, ridge lines of the candidate fingerprint are compared to those of “reference users“, previously registered during the enrolment process.
Every fingerprint recognition system is divided into two different stages:
- The extraction, in which ridge’s data are extracted from captured image by a fingerprint sensor. All extracted datas are saved into a template.
- The comparison or matching, in which two different templates are mathematically compared to determine whether they belong or not to the same person.
Fingerprint recognition systems are classified according to the used technics in the two main categories hereunder:
Verification or 1 : 1 (one to one) comparison:
Such a technology must determide if two templates belong to a unique person. The candidate’s template is compared to the templates of a “reference user” previously collected and registered during the enrolment process.
Identification or 1 : N (one to many) comparison :
Such a technology must determied who is the owner of a template. The candidate’s template is compared to the contents of a database containing a large number (N) of templates previously collected and registered during the enrolment process.
