Multimodal biometric authentication systems

18 March 2021

The clear benefit of using biometric identification has been discussed, researched and documented, so much that its implementation across industries and sectors is accelerating. Biometric system technologies have a wide range of applications and will provide enhanced security over traditional methods of passwords and ID documentation. Using one mode (unimodal) biometric system will still leave a significant chance of errors and fraud. To overcome these weaknesses in unimodal systems there is a shift towards the adoption of multimodal biometric authentication.

These systems will integrate information from more that one biometric modality simultaneously and so improving the performance of the individual biometric system. By requiring the physical presentation of a combination of face, voice, iris, or fingerprint will make the systems more secure without negatively impacting user experience.

What are the benefits?

Reducing the Error in matching

By using more than one type of biometric information will reduce the chance of both matching errors and false matching, which would allow an imposter to gain access.


Increased reliability in recognition

Having one or more biometric modules gives a higher recognition threshold. If one trait identifier should fail to match the is still another to use to identify the individual.


Higher security threshold

The risk of spoofing can be almost eradicated when implementing the use of effective multimodal biometric authentication systems. Spoofing is when an unauthorised person is able to imitate the identity of an authorised user. Research has shown the potential for cloned artificial finger moulds to be accepted in verification procedures.


Noisy Data rectification

Sometimes during enrollment, there is a defect or error in the data collected (noisy data), In such cases, at the time of authentication, the data will not match and lead to false rejection due to the data not being comparable. With the use of a multimodal biometric system the noisy data can be rectified by using multiple biometric data for verification.



Due to either illness or disability, some people may lack the required stand-alone biometrics.


What are the Applications?

Multimodal biometric systems can be beneficial in much the same way that unimodal biometric systems are currently used as they improve what is currently available. They are, however, more important to consider in industries such as healthcare, finance, and defence where both accuracy and security are the top priority. Due to the advantages of these systems, large companies are also adopting them to protect their data and assets.


The Multimodal Biometric Authentication Solution

The BioBox was designed to establish a physical link between biometric identity, digital information and the person themselves. With the capacity to store and generate data in a secure system,  our diverse software allows for flexibility without jeopardising security standards. Easy, secure and fast processing, BioBox ID enables authorities to capture and store the data anywhere in under 4 minutes.

With face, iris and FBI certified fingerprint capabilities; this product permits multi verification, encoding and generating EFT files making ID fraud extremely difficult. The choice of included products is entirely up to the client. We are able to add or remove elements based around the necessities of the project. Stored in a waterproof, shockproof, compact case, it allows the user ease of transportation between locations.

Not only is the BioBox adjustable to a specific requirement, but the software we have developed is also customisable. The flexibility ensures BioBox is adaptable to various usage scenarios from commercial offices to governmental bodies; the software’s capabilities are continually being upgraded to meet any potential challenges.
