Biometrics – Identification or Verification

At +Accsys, we get asked everything from how fingerprints form, to what is the best solution, identification or verification.

Then there is optical or capacitance as a choice, too.

Lots of choices.

The Identification or Verification question is interesting, though.   Biometric identification is simple, you present the required body part to the reader, and it recognises you based on an algorithm saved on the system.   Verification requires media or a pin code first, then you are asked to verify that it has the right person by presenting your finger or face etc.

Verification is more secure, as it relies on the double affirmation.    However, unless pin code is used, it requires the employee to carry media, with the attendant risk of loss or “I forgot it at home”, not to mention the cost of the media.

While verification does seem to be a slower choice, in certain circumstances it can speed up the operation, as the memory search for the correct biometric algorithm can take time, on certain devices and with some software solutions.

It is also important to note that verification, through limiting the search space, allows for handling of much larger quantities.  Our Accsys IT Director, Dr Liam Terblanche gives pension payouts as an example.   He says that if we were to use biometrics for handing these out, we would definitely be looking at verification rather than identification, because of the sheer volume.

There is no question that identification has achieved more common usage, though.   The practicality of not requiring media or memory (remembering a pin code) has given this option the edge.

Its all about the numbers - retirement age

Weight, height, age, dress size, shoe size, all numbers that we (and the media) use to define people. I was fascinated by an article from the Leicester Mercury where the age of each witness to a bus crash in January were carefully listed. Sue Kellett, 56, whose front garden is bordered by the wall, was one of the first at the scene.

Is the employee toxic or simply disengaged?

Is the employee toxic or simply disengaged?  And how to tell? Dissecting Employee Behaviour We spend hours of management time dissecting employee behaviour to ensure that not only is each employee delivering to a minimum expectation, he or she is not actively undermining the effectiveness of the business. We design KPAs (or KPIs, or whatever we want to call them), we run regular appraisals, we discuss career paths and succession plans, and  as long as toxic employees are delivering on their job description, we keep them! It’s only after they leave, when you hear the collective deep breath of relief from colleagues and management, that you can be absolutely sure of the negative impact. Underperformance vs Undermining My view has changed – rather an underperformer, than an underminer. So what to do? Once you have firmly established that undermining is the problem, the first step is to tell them that you are onto them! Never an easy task, because very few p...

Which Wolf are you Feeding?

Which Wolf are you Feeding?   An old Cherokee is teaching his grandson about life: (Sources – See below) A fight is going on inside me, he said to the boy.   It is a terrible fight and it is between two wolves.   One is evil – he is anger, envy, sorrow, regret, greed, arrogance, self-pity, guilt, resentment, inferiority, lies, false pride, superiority and ego. The other is good – he is joy, peace, love, hope, serenity, humility, kindness, benevolence, empathy, generosity, truth, compassion and faith. This same fight is going on inside you – and every other person, too. The grandson thought about it for a minute and then asked his grandfather “Which wolf will win?” The old man replied simply “ The one you feed”. When I came across this story in a thriller by Michael Robotham, my reaction was immediate.  This is a great hook for creating positive thinking and, importantly to our business, a new way to approach an age old concern.
