Abstract:

At present, there is an increasing need to protect workplace entry and specially guarded premises. In addition to standard access systems on a chip cards are getting to the fore of biometric identification systems such as readers for fingerprint, biometric scans faces and others. Biometric readers face still improve, but still have a lot of blind spots, thanks to which their reliability and user-friendliness decreases. One such problem is the light intensity in the room where the reading device is located. The varying intensity of the light in the room causes a different illumination of the person’s face. It emphasizes or suppresses the main points of the face that needed for user authorization, and the whole identification process is prolonged and difficult. The reliability value is significantly different from the value given by the manufacturers. It is very important to highlight on this problem and begin to address it by altering the current production engineering.

Abstract:

Biometric user identification is a highly topical theme these days. The most widespread areas are identification of a person on the basis of fingerprints and identification on the basis of facial features. Testing was performed on the 4 biometric systems. Systems using fingerprint were LA 2000M and iEvo ULTIMATE, and systems disposing even the scan faces were D-Station, IFace 800. Measurements showed that the higher reliability have biometric identification systems which identify the person on the basis of one parameter. From the results it is also seen that sabotage of biometric identification devices that identifies on the the basis of two or more parameters is much simpler than those that identify only using fingerprint or scan of face.

Abstract:

Biometry in the field of identifying people is a highly topical theme these days. The most widespread area is identification of a person on the basis of fingerprints, nevertheless scanners of the bloodstream, iris and retina in particular are undergoing development, as well as identification on the basis of facial features. In the case of scanners which distinguish people according to their face, user problems are appearing. One of these problems is the surrounding environment of the scanner device, in particular light conditions. According to tests, it is necessary to conduct identification of people under laboratory conditions, which is not acceptable from the user perspective. It is essential to consider this problem and to innovate and extend the system for identification on the basis of facial features. It is necessary for the system to react, if possible, with a minimal error rate and within the fastest response time. Through the help of testing light conditions, an improvement was achieved in the capability of identifying facial features, and at the same time a further modification was proposed to perfect the existing technology.
