Learn about Different Types of Multi-biometric Systems
Multi-biometric systems have come a long way by addressing biometric issues and concerns in a better manner. With constant research in the field, the developers and manufacturers have come up with different types of multi-biometric systems, each one to entertain the specific requirements. You can continue reading further to learn about various multi-biometric systems available in the market.
Multi Sensor Biometric Systems
As the name suggest, these biometric systems consist of multiple sensors to capture the data more than once and then combine them to deliver accurate data matching process. For instance, 2D cameras as well as infrared sensors can be used in a multi-biometric system to capture the images of an individual in different types of illuminations. The process provides a higher sophistication level to the security offered by these systems.
Multi Algorithm Biometric Systems
Algorithms are important parts of biometric systems to carry out the process of sampling and identification. How about combining more than one algorithm to enhance the level of security? The multi-algorithm biometric systems are economical than other types, as extra sensors and other devices are not required. Though, one can expect them to be more complex.
Multi Sample Biometric Systems
In this type of biometric systems, the multiple samples of the same physical trait are captured to produce samples that are good enough to provide more secure identification. For instance, apart from the front profile of a person’s face, the side profiles can also be used to prepare the identification samples.
Multi Instance Biometric Systems
You have 10 fingers and 2 irises and thus, biometric technology can make use of all the fingers or both the irises to prepare different instances and combine them to form specific biometric samples. As it is clear, better biometric access control arrangements can be acquired using the procedure.
Multimodal Biometric Systems
A simple way of enhancing the utility of biometrics is to combine samples from two physically uncorrelated features of an individual and the resulting system can be called the multimodal biometric system. For example, voice patterns can be combined with face recognition or iris patterns with fingerprints and so on. Going further, the hybrid biometric systems have been devised to combine, say two iris samples with three face patterns and so on.
In this way, multi-biometric systems keep on evolving in different types, thereby making biometrics a popular technology for identification and access control.
