And Face Recognition Biometric Systems

Biometric systems, facial recognition, are becoming very popular today. However, there is some controversy around this security solution. This is because there have been incidents with biometric systems of this type, in which they have not been able to identify faces with accuracy. These problems have not been very frequent, but they have to open a debate. However, what needs to be clear is that facial recognition is a safe and accurate.

Biometric systems, facial recognition, work by measuring the immutable traits of the face. The distance between the eyes, thick lips, the shape of the cheekbones and other qualities of the face remain constant throughout life. For this reason, when a face appears to the system a second time, recognizes it after a quick scan. Newer systems use software that uses three-dimensional images for accuracy.

When a person or entity think of biometrics, you must know that there is nothing perfect in the world. Thus it can be stated that there is a security method that is 100% secure. A As with any machine, there is the possibility that some errors occur, in biometric systems.

A face detection system can fail in one of two ways: it can identify an unfamiliar face to be genuine (false positive), or deny the identification of a genuine face (false negative). The effectiveness of a facial recognition system can be affected by lighting conditions, the expressions of the face and other external factors. The possibility of false positive or negative can not be ruled out entirely.

Despite this, this application can be considered a better choice than conventional security solutions. In fact many experts, security systems, attest to the capabilities of these biometric systems. Other scholars are hesitant to give numbers and ensure that these systems are effective in more than 90%, so it may be more reliable than other security mechanisms.

The high rates of effectiveness of facial recognition biometrics can be taken to control casinos for cheaters. Also, schools can adopt them as attendance and truancy controls.

These systems have already begun to be used by police agencies of the United States, which have achieved remarkable results in their fight against crime.
