The success of a biometric system often depends on choosing the right biometric modality, but it isn\u2019t easy. Careful research that includes rigorous comparisons of modality strengths and weaknesses is an important element to help select the right hardware. Factors to consider in the comparison may include: specifications, convenience, usability, acceptability, effectiveness, and budget.<\/p>\n

Choose the right biometric modality.<\/figcaption><\/figure>\n

There are many biometric modalities available including fingerprint<\/a>, finger vein, facial recognition, iris<\/a>, voice, signature, gait, and more. It\u2019s important to understand that not all biometric modalities<\/a> have the ability to meet the requirements of every organization, it depends largely on the industry application context.<\/p>\n

It\u2019s important to realize that there is not one biometric modality which is best for all conditions and implementations. Many factors must be taken into account when implementing a biometric device including location, security, acceptability, and ease of use. However, performance and cost may vary when taking into consideration deployment requirements and environment. At times deployments may require combining two biometric modalities (i.e. \u201cmultimodal\u201d biometrics) to ensure optimal accuracy. Choosing the right modality is important to maximize the full benefits from a biometric system.<\/p>\n

There are some important factors which should be considered before choosing a biometric modality. These include:<\/p>\n

    \n
  1. Accuracy<\/strong><\/li>\n<\/ol>\n

    Accuracy is one of the most important aspects to assess when choosing a biometric modality. It is based on several criteria including error rate, false acceptance rate<\/a> (FAR), identification rate, false reject rate<\/a> (FRR) and additional biometric system standards.<\/p>\n

      \n
    1. Anti-spoofing capabilities<\/strong><\/li>\n<\/ol>\n

      As biometric recognition systems become more widespread, more attention has been given to possible direct attacks, where potential intruders may gain access to the system by interacting with the system input device. Such attempts are commonly referred as spoofing attacks. Strong anti-spoofing protection is a must have capability for the right biometric modality.<\/p>\n
