Last week we took a look at biometric identification verification. This week let’s review the advantages and disadvantages of this type of access verification.
Biometric identification verification refers to an automated system that can identify an individual by measuring their physical and behavioral uniqueness or patterns, and comparing it to those on record.
Biometrics can also provide you with convenience and security, by enabling a machine to verify the individual by itself and to respond to the individual’s requests. Through the use of such physical controls as access control, and punch card maintenance, user restrictions on certain apparatus can be made possible with an automated verification system.
In a nutshell, advantages to this type of identification verification include:
- No more forgotten or stolen passwords
- Positive and accurate Identification
- Highest level of security
- Offers mobility
- Impossible to forge
- Serves as a key that cannot be transferred
- Safe & user friendly
Biometrics systems can be quite flexible and easily scalable. You can use higher versions of sensors and security systems based on your requirements.
The return on your investment is also high because you can avoid fraud including “buddy punching”. This can lead to lowering payroll costs, accurate calculation of work hours and reduced management time. Security is improved and you can also easily implement new consistent policies and procedures at the same time.
Updated policies and procedures go hand in hand with biometric verification systems, because they allow you to keep track of a user’s activities. It is possible to know who has been doing what at a given time and when. These benefits are not available in traditional authentication systems, because it is not possible to know/prove who actually input the information.
However, as with almost everything, errors can and still do occur. The error rate for most biometric devices is around 1%. This means that out of 1000 people biometrically scanned, 10 of them will be misidentified.
This will happen for a variety of reasons, including what type of scan was done. Here are several types of scans and their inherent errors:
Keystroke: The keyboards of other countries are different (Germany, France)
Fingerprint: Injury, whether temporary or permanent, can interfere with the scanning process
Iris Scan: It is a difficult technology if the distance is larger than a few meters and if the person is not standing still. As with other photographic biometric technologies, iris recognition is susceptible to poor image quality.
Voice: It is possible to steal an example of someone’s voice, file storage is difficult; it uses a great deal of storage and it is an overall expensive method.
The biggest disadvantage of using a biometric identification verification system is the same one that many new technologies encounter – cost. Because of this, organizations need to make conscious decisions before making the switch. We have already reviewed the final ROI, but, it is important to note that switching over will mean that you will be incurring the upfront costs of replacing hardware and software. It is also important to review your existing and potential network needs and associated costs.
It is also important to remember that biometric identification verification systems, like any access control system, are far more powerful when integrated with a video management solution that can provide visual verification. In cases of false negatives, where an “approved” individual is denied access by a biometric system, live surveillance video of the “reader” site can allow security administers to override the system and allow for entry, from wherever they are monitoring the system. And in cases of false positives, recorded video of an unauthorized individual gaining access to a restricted area is critical evidence that can be used to investigate security breaches.
