Post September 11, 2001, biometric technologies came into focus as never before. Since then, various government agencies and private enterprises across the world have depicted keen interest in implementing the highly secure biometric solutions. The choice of a particular biometric technology for implementation largely depends on the type of application and the level of security required. Though biometrics is a useful tool to address these newfound concerns of the customers, no single biometric technology has the capability of fully satisfying the customer demands.
Multi-Modal biometrics - the use of multiple biometric indicators for implementation - has thus emerged as a possible alternative. The use of more than one physiological or behavioral characteristic for enrollment and verification or identification is expected to enhance the security features of complete solution. Multi-modal biometrics usage is being actively considered in applications involving Border Control, Physical Access Control, and PC/Network security.
Advantages of Multi-modal Biometrics
The integration of two or more types of biometric verification systems helps to meet stringent performance requirements set by security-conscious customers. Here is a brief look at a few advantages of implementing multi-modal biometric solutions:
Using multiple biometrics helps in improving the accuracy of the overall system.
Such solutions also provide a secondary means of enrollment and verification or identification in case sufficient data is not extracted from a given biometric sample.
They also have the ability to detect attempts to spoof biometric systems through non-live data sources such as fake fingers.
Key Industry Trends
Different combinations of biometric technologies can be used such as those involving finger-scan along with face recognition, face recognition with iris recognition, and face recognition with iris recognition and finger-scan for commercial deployments. Another interesting combination involves the use of face recognition, voice verification and lip movement recognition.
Solutions based on face recognition and iris recognition are expected to occupy the majority market share in the multi-modal biometrics market in future. The use of a common imaging device for capturing the face and iris template is expected to cut down the overall cost of implementation. This development is expected to be the major driver for the growth in implementations based on iris recognition and face recognition. This combination would also boast of high accuracy as the underlying iris recognition solutions are deemed to be most accurate among biometric solutions.
The increased usage of smart cards across the globe has also boosted the potential in biometrics market. Growing demand for high memory smart cards of 32k and 64k memory enable storage of more than one biometric template in one card.
Another positive development is the steady growth in the number of vendors offering multi-modal biometrics solution across the world especially; in Asia-Pacific. Vendors such as Alpha Engineering, BlueNics, DreamMIRH, Evermedia Co. Ltd., HumanScan, ID Tech Co. Ltd. and Keyware are expected to play a significant role in contributing to the growth in multi-modal biometrics market.
Despite these positive trends, actual implementations will act as reference sites for future customers and will determine the rate of adoption of multi-modal solutions. The success of these reference projects would prompt new customers to implement these solutions.
Another important issue that has to be tackled is of adoption of common standards. Over the last few years, efforts have been made by organizations such as BioAPI to develop common standards for each of the biometric technologies. However, vendors have been a little slow in adopting these standards and this factor could also hinder the growth in multi-modal biometrics implementations.
The total cost of implementing multi-modal solutions would also be an important criterion affecting the final choice of the customer. The higher security provides would have to be justified by a higher price paid for by the customer.
Thus, keeping all these factors into consideration, one can predict a steady growth in demand for multi-modal biometrics solutions in future. The adoption rates though, would depend on the effectiveness of these solutions to address the concerns of customers.
