Multimodal biometric recognition refers to the combination of two or more biometrics used in the recognition system. For example, the system combining face recognition and iris recognition can be considered as multimodal biometric recognition system. Is multimodal biometric recognition technology safe?
Multimodal biometric technology provides supplementary information between different modes in order to improve the recognition performance in terms of accuracy and reliability, so as to overcome the shortcomings of a single biometric system. There are two types of biometric technology, including physiology (face recognition, iris recognition and vein recognition) and behavior (signature recognition, gait recognition and speech recognition). In order to meet the needs, some multimodal biometric systems are ready to capture and match these different types of biometrics.
Research shows that multimodal biometric system is a solution to improve the accuracy and reliability of biometric system. Recognition based on a variety of biometric technologies represents an emerging trend. There are many reasons to promote the development of biometric technology. The most irresistible reason to combine different ways is to improve the efficiency of recognition. Another trend that promotes the development of multimodal biometric system is customer preference, which needs higher security. In addition, multimodal biometric system can effectively deal with various problems, such as noise data, in class variation, limited degree of freedom, non universality, deception attack and unacceptable error rate that may be caused by unimodal biometric system.
Multimodal biometric system is likely to be widely used in a variety of civil applications, such as: Bank security, check cashing and credit card transactions, information system security, such as access to databases through login permissions. Worldwide, the market for multimodal biometric systems is expected to rise due to their increasing popularity in government and transportation applications. The utility of these systems in national ID biometric passport and visa is mainly to promote the multimodal biometric market.
In addition, the “global biometric market (2014-2020)” report also points out that due to the increase of terrorist attacks and crimes, the increase of security issues requires a huge demand for high-level security. In addition, government programs are also increasing, such as e-passport, national identification program and other border control projects, including Eurodac, visa information system (VIS) and new generation Schengen information system (sisii), which have contributed to the development of multimodal biometric technology market. Therefore, the increasing use of multimodal biometric technology to improve the level of security is expected to create huge opportunities for this market in the next few years.
The use of multimodal biometric systems has become prominent because multiple biometric data are collected from individuals to make identification more accurate. Therefore, in order to achieve these goals, a lot of technological progress is needed. It is also a major challenge for market participants who must maintain the reliability and accuracy of biometric systems while reducing the costs involved.
