Multimodal biometric authentication system the use

The risk on the biometric database and data presented for biometric check. Multimodal biometric system[ edit ] Multimodal biometric systems use multiple sensors or biometrics to overcome the limitations of unimodal biometric systems.

Biometrics: authentication and identification (2018)

Adaptive biometric systems[ edit ] Adaptive biometric systems aim to auto-update the templates or model to the intra-class variation of the operational data.

In general, the matching algorithm performs a decision based on a threshold that determines how close to a template the input needs to be for it to be considered a match. Image acquisition errors consist of failure-to-acquire FTA and failure-to-enroll FTE rate whereas matching errors comprise false non-match rates FNMR in which a legitimate person is rejected and a false match rate FMR where an impostor is granted access.

This is most commonly caused by low quality inputs. With these biometric ID cards, fingerprints are used to confirm the identity of the bearer of the card before he or she is given access to governmental services or healthcare. Put it in another way: In addition, in a biometric control application, the rejection or acceptance rate are intertwined and can be tuned according to an acceptable level of risk.

They can combine digital fingerprints, a photo and an iris scan for greater reliability. Fingerprint scanners and cameras at border posts capture information that help identify travelers entering the country in a more precise and reliable way. The use of biometrics has a number of benefits.

Biometrics is the science of analyzing physical or behavioral characteristics specific to each individual in order to be able to authenticate their identity.

Civil data, a photograph of the holder and two fingerprints are digitized within the microprocessor ensuring encryption and protection of this data. Biometric sensor cards Another form of delivering a safe and convenient way to authenticate people has been enabled with the integration of fingerprint scanner into smart cards.

Multimodal as well as unimodal biometric systems are sometimes vulnerable to spoofing. Why Multimodal Biometrics is Required? Feature level fusion is believed to be more effective than the other levels of fusion because the feature set contains richer information about the input biometric data than the matching score or the output decision of a classifier.

In contrast to passwords, badges, or documents, biometric data cannot be forgotten, exchanged, or stolen, and cannot be forged. Multimodal biometrics uses information from two or more biometrics — e. For example, they are not as subject to the effects of stress, in contrast to identification by behavioral measurement.

The Top 5 Reasons to Deploy Multimodal Biometrics

Biometric functionality[ edit ] Many different aspects of human physiology, chemistry or behavior can be used for biometric authentication. The risk of error also varies depending on the environment and the conditions of application.

Measurability collectability relates to the ease of acquisition or measurement of the trait. Identification answers the question "Who are you? Matching-score level fusion consolidates the scores generated by multiple classifiers pertaining to different modalities.


Most developing countries have weak and unreliable documents and the poorer people in these countries do not have even those unreliable documents.

On the portability side of biometric products, more and more vendors are embracing significantly miniaturized biometric authentication systems BAS thereby driving elaborate cost savings, especially for large-scale deployments.

Multimodal biometric systems can obtain sets of information from the same marker i. According to Agamben, biometrics turn the human persona into a bare body. The technique to be adopted to integrate the information.

Aadhaar number is a digit unique identity number issued to all Indian residents.All the biometric systems we discussed till now were unimodal, which take single source of information for authentication.

As the name depicts, multimodal biometric systems work on accepting information from two or more biometric inputs. A multimodal biometric system increases the scope and variety.

multimodal biometric system information reconciliation can occur in any of the aforementioned modules (see Figure 1). (a) Fusion at the data or. Multimodal biometric system makes use of different biometric traits simultaneously to authenticate a person’s identity.

Robustness and high security of authentication can be achieved by using the multimodal biometric. Multimodal Biometrics Authentication Framework for a novel multimodal biometric authentication framework for online trait in use.

Multimodal biometric system uses information obtained from. This is the reason that multimodal biometrics are more accurate than unimodal or any other authentication system.

Increased and Reliable Recognition: A multimodal biometric system permits a greater level of assurance for an accurate match in verification as well as identification modes.

Multimodal Biometric Systems

The multimodal biometric system consists of multiple traits of individual information, so it is necessary to secure the template from the database. Thus the proposed system, used to encrypt the template is RSA, which is a.
