The rise of multimodal biometrics and the challenges they present

The landscape of physical security is undergoing a transformative shift, with traditional swipe card systems being gradually replaced by the more sophisticated multimodal biometric solutions. These advanced systems significantly raise the bar for security measures, while also offering unprecedented convenience and speed in building access.

This paradigm shift towards multimodal biometrics represents not just a technological evolution, but a strategic rethinking of access control and personal identification. The implications for physical security are massive, promising enhanced protection against unauthorized entry and a more seamless interaction for users.

For those involved in integrating physical security systems, it’s vital to fully understand the technological advancements and the challenges they bring, particularly in terms of integration and interoperability. Staying informed and adaptable is key to leading in this dynamic industry.

The rise of multimodal biometrics

The shift towards multimodal biometrics is fueled by the demands for quicker access, enhanced security, and greater ease of use. Such systems are becoming increasingly popular, especially in settings where congestion during peak times at entry points presents a challenge.

“Speed, security, and convenience are the three driving factors behind growth,” said Steve Bell, Chief Technology Officer at Gallagher Security. “Large numbers of customers have migrated to Biometrics on speedstiles to eliminate peak hour congestions in their facilities. Using the MorphoWave Compact 3D Finger Scanner we can process over 45 transactions per minute through a single gate. In lower traffic times staff can access entries and exits without stopping at the gate. The availability of three independently assignable modalities being biometric, token and face – or the mix of one two or all three provides the ultimate in flexibility and convenience for the user.”

By incorporating various biometric technologies like fingerprint and face recognition, multimodal biometric systems have transformed the way buildings are accessed. This combination enhances security measures, reducing the chances of unauthorized entries, and streamlines the process of entering buildings, rendering physical badges, keys, or PIN codes unnecessary.

“Multimodal biometrics have revolutionized building access, offering a seamless, secure, and personalized entry experience,” said Hanchul Kim, CEO of Suprema. “By integrating multiple biometric modalities, such as fingerprints and facial authentication, these systems significantly enhance security and minimize the risk of unauthorized access. Users benefit from a simplified entry process, as they no longer need to manage badges, keys, or remember PINs, facilitating quicker and more efficient access.”

The incorporation of advanced technologies like Neural Processing Units (NPUs) based on deep learning AI algorithms further enhances the accuracy of biometric recognition, ensuring high performance even with low-quality fingerprints or facial recognition across various ethnicities and in different lighting conditions. This level of precision and convenience is especially beneficial in high-traffic areas, providing a seamless entry experience without compromising on security.

Navigating integration and interoperability challenges

Despite the advantages of multimodal biometrics, the issue of integration and interoperability between different biometric systems remains a significant challenge. Current standards and protocols, while evolving, still fall short of fully addressing these concerns.

“In fact, they lag well behind,” Bell said. “Most biometric manufacturers understand that old ISO and ANSI type templates are far inferior to current template algorithms. Most leading algorithms are proprietary and not compatible. In the world of access control almost all biometrics (and other tokens) communicate with the controller via Wiegand or OSDP solving integration issues. Multi-technology enrolments still require due consideration and planning.”

The complexity of integration is further compounded by varying data formats, protocols, and proprietary technologies. Despite these challenges, efforts are underway to establish a comprehensive framework for biometric data interchange.

“Integration can be complex due to varying data formats, protocols, and proprietary solutions,” said Kim. “Current standards and protocols are evolving but still need more development to fully address compatibility concerns. Organizations like the Biometrics Institute and standards such as ISO/IEC 19794 series are working towards establishing a comprehensive framework for biometric data interchange formats.”

The future of biometric physical security

The adoption of multimodal biometrics is set to redefine the physical security landscape, offering a blend of enhanced security, speed, and convenience. As the industry moves forward, the focus will increasingly shift towards resolving integration and interoperability issues to ensure that these advanced systems can be seamlessly incorporated into existing security infrastructures.

For systems integrators, staying informed about the latest developments in biometric technologies and standards is essential to navigating the complexities of integration and delivering solutions that meet the evolving needs of clients.

In short, multimodal biometrics are transforming the way we think about and implement physical security measures. By embracing these technologies and addressing the challenges they present, systems integrators can play a pivotal role in shaping a more secure and efficient future for access control.
