Biometric personal identification systems
You can control the entry and exit times of your employees with the personnel recognition system.
At the same time you can prevent staff from accessing unauthorized areas
Why Use Biometrics-Based Personal Identification?
Biometrics-based personal identification tries to answer the questions “Who you are ?” and “Are you who do you claim to be?” Personal identification, regardless of the method, is present in our daily lives. For example, we often have to prove our identity in our daily life to gain access to our bank account, to enter a protected website, to draw cash from the ATM, to log on to a computer, to claim welfare benefits, to cross national borders, and so on.

Biometric identification systems can be grouped based on the main physical characteristic that lends itself to biometric identification:
- Fingerprint identification
Fingerprint ridges are formed in the womb; you have fingerprints by the fourth month of fetal development. Once formed, fingerprint ridges are like a picture on the surface of a balloon. As the person ages, the fingers get do get larger. However, the relationship between the ridges stays the same, just like the picture on a balloon is still recognizable as the balloon is inflated.
- Hand geometry
Hand geometry is the measurement and comparison of the different physical characteristics of the hand. Although hand geometry does not have the same degree of permanence or individuality as some other characteristics, it is still a popular means of biometric authentication.
- Palm Vein Authentication
This system uses an infrared beam to penetrate the users hand as it is waved over the system; the veins within the palm of the user are returned as black lines. Palm vein authentication has a high level of authentication accuracy due to the complexity of vein patterns of the palm. Because the palm vein patterns are internal to the body, this would be a difficult system to counterfeit. Also, the system is contactless and therefore hygienic for use in public areas.
- Retina scan
A retina scan provides an analysis of the capillary blood vessels located in the back of the eye then the pattern remains the same throughout life therefore A scan uses a low-intensity light to take an image of the pattern formed by the blood vessels. Retina scans were first suggested in the 1930’s.
Biometric identification systems getting more popular
- Iris scan
An iris scan provides an analysis of the rings, furrows and freckles in the colored ring that surrounds the pupil of the eye. More than 200 points are used for comparison. Iris scans were proposed in 1936, but it was not until the early 1990’s that algorithms for iris recognition were created (and patented). All current iris recognition systems use these basic patents, held by Iridian Technologies.
- Face recognition
Facial characteristics (the size and shape of facial characteristics, and their relationship to each other). Although this method is the one that human beings have always used with each other, it is not easy to automate it. Typically, this method uses relative distances between common landmarks on the face to generate a unique “faceprint.”
Although the way you sign your name does change over time, and can be consciously changed to some extent, it provides a basic means of identification.
- Voice analysis
The analysis of the pitch, tone, cadence and frequency of a person’s voice.
