Evaluating Advantages and Disadvantages of Biometric Identification

Posted In Technology Reviews - By Techtiplib on Friday, October 17th, 2014 With No Comments »

Securing office premises as well as sensitive information happens to be one of the major responsibilities of business owners. Regardless of its size, every organization strives to adopt ways that help them to ensure security of their business. In doing so, enterprises have moved beyond traditional means of identification and have taken to biometric identification as their chosen safety measure. Depending on their preferences, organizations can choose from biometric scanners that are capable of performing fingerprints or iris scans, palm or face scans and so on.

Just like any system, biometric identification has also got its share of advantages and disadvantages. But before delving deep into those, let us understand what biometric identification is all about.

What is Biometric Identification?

It is a technique of using physical or behavioral features of a person to identify him/her. Let us take fingerprint recognition as an instance to understand this technique elaborately. When a biometric scanner captures fingerprints, it compares this captured data against a database of every authorized user’s fingerprints. If the captured fingerprints match with an enrolled user, then the person is identified and granted access to the premise. This also works with behavioral patterns where speech of an individual or the manner he/she types on a keyboard can also be analyzed and used for identification.

Usually, biometric identification devices are installed on doors of secure locations. The task of these devices is to identify authorized personnel and allow them to enter the premises, whereas denying entry rights to unauthorized people. Such biometric identification systems are used in different places differently. While some companies choose to implement this system to secure their computer network, some schools on the other hand, prefer using fingerprint scanners to manage and monitor attendance of students and staff. So, it can serve a lot of purposes.

Now that the basics are cleared, let us proceed towards advantages and disadvantages of biometric identification system. 


  • It enhances security of a location or premise in a convenient way.
  • It reduces chances of fraud, as physical and behavioral features are not easy to forge. This also minimizes chances of proxy biometric data entry.
  • It eradicates problems such as forgotten passwords, lost or stolen IDs. Except for any serious physical injury or disease, biometrics of an individual cannot change and is always available to him/her. Hence, an identification system of biometrics is a consistent and permanent solution.
  • It substitutes the need for remembering hard passwords or PINs that may be observed or shared by others. Since, biometrics is not engineered; it cannot be shared or used by multiple users. So, this identification system is a potent one.
  • It ensures noteworthy cost savings and increased return-on-investment (ROI) in matters such as time and attendance, issuing duplicated ID cards, loss prevention and so on.
  • It links an individual unmistakably to an event or transaction so that the system can know automatically who did what, when and where.
  • It offers a scalable and robust control solution for network and facility access.


  • Biometric identification machines are comparatively expensive than traditional system.
  • Some people may actually see it as an invasion of privacy.
  • Biometric identification system cannot accommodate changes to biometric over time. With age, illness or injury of some sort, such systems cannot identify the user and grant him/her access.
  • It is not fit for chemical industry where the employees stand the chance of getting affected by chemicals.

Thus, judging from the above evaluation, there are more advantages of implementing biometric identification system in an organization than its disadvantages. Although, it may involve an initial expense that seem lot for small organizations but it is worth it. This is a one-time investment that can ensure accurate and proper identification for many years.
