We continue with the business and technical factors which need to be taken into consideration if you are going to use Biometrics:

Third, after you have decided that you want to implement a biometric system, it is important that you get an understanding for the Rate of Return On Investment (ROI) you will be getting from it.  In order to do this, you can first conduct a “Pilot Project”.  For example, if your implementation calls for the deployment of five fingerprint scanners at five different access points at your place of business, first consider implementing only one fingerprint scanner at one primary access point, for a period of time (three months).

By doing this, you can then quantify your ROI if you want to do a system wide implementation.  Also, this will give you time to see how your employees will react to the use of a biometric system.  You can always implement a system wide biometric deployment, but you run the risks of not knowing what your ROI will be, as well as your employee’s perception and acceptance of the new technology ahead of time.

Fourth, one of the cardinal rules in a good security policy is that never rely upon just one means of security as your only line of defense.  You should have multiple layers of security.  In biometric terms, this means having a “multi-modal” security system (a future article will specifically address the applications of “multi-modal” biometric security systems).

Before you implement your biometric system, it is very important to examine to see how well you can implement it along side with your existing security systems (such as CCTV, card swipe, numeric keypad entry, etc.)

After you taken into account the above mentioned factors, you are probably asking yourself, as the owner of your business, what type of biometric system will work best for my place of business?

This is a difficult question to answer, without having first conducted a security audit, and assessing your needs and budget.  In general terms, biometric system applications fall into two areas for businesses:  (1)  Physical Access Entry Security; and (2)  Computer and Network Security (this is also known as “Single-Single On Solutions”, in that your fingerprint becomes your password-this eliminates the need to remember multiple passwords)

In these types of applications, hand geometry recognition technology and fingeprint recognition technology are deemed to be among the best.  These two technologies also work together well in a “multi-modal” scenario.  The hand geometry scanner can be used at the primary access entry points in your business, and the fingerprint reader can be used to provide for a second level of security for the more sensitive places within your business.

Biometric systems, like all other technologies, have performance standards or metrics which you must evaluate first before implementing them at your place of business.  This will be looked at in the next blog.
