Trends in Biometric Technology 2015

download (12)The world today moves ahead with technological advancements every day. In this digital age where dependence on online businesses and marketing is growing, the security threats are also not much behind. In this field, Biometric technology has played a massive role in enhancing security, which is a step-up from the previous password protection or Personal Identification Numbers (PINs) methods.

Biometrics is quite useful and better for a number of reasons. It uses technology that examines a human body’s characteristics like DNA, facial patterns, eye retina, and hand measurements for authentication processes. A person is identified by the blood vessel pattern beneath the skin – which is unique to each individual. Such a process is quite secure as cloning a human’s DNA or facial patterns is a much harder task than cracking passwords. This year saw various trends in Biometrics Technology, which is most likely to rise in the coming years.

Some of the trends are as follows:

1. Incorporating biometrics in money transaction businesses

Online shopping is a major source of income and a usual trend these days thereby holding many security threats as well such as credit card frauds. In this case, biometric plays a very important role as recently MasterCard is about to launch a facial recognition service wherein customers can complete transactions with just a selfie.

The various shopping portals will include a Biometric scanner in their shopping process with facial recognition system which will help in completing transactions with a single scan of the customer’s face.

2. Mobile Biometric System

Mobiles have been a major part of our lives. This year the number of mobile phone users has reached almost 6 billion. Therefore, government and private commerce are converging to mobile biometrics to speed up the identification process. This trend is rising because biometrics cannot always be carried out in a closed location. Sometimes, biometric identifications go places where people go like stadiums, markets or simply public places.

One great example of the Mobile Biometric System is the Iraqi automated border control system. There are at least 100 mobile biometric checkpoints with over a million registrations. This helps in keeping a check and protecting them from insurgents.

3. Cloud Based Biometric Security

This is in relation to the mobile biometric system. The details of the biometric are coupled with a cloud-based server, which in response helps in pacing the verification process. Cloud saved biometric data is more secured than locally saved biometric data.

4. Biometric Single Sign on (SSO)

Another rising trend seen is the use of a Biometric Single Sign on (SSO). With this system, the individual does not have to remember ID’s and passwords for every account. This helps in speeding up the work and additionally helps to swap the problem of remembering multiple passwords.

5. National Security Measures

Biometric system comes in very handy to the governments who are switching to it in order to enhance national security. The main reason for this is that there are a high number of digital interactions between countries, with a highly vulnerable security risk. Using Biometrics decreases the hack rate and opens a channel for safe information transfers.

6. Future Proof Technology

Biometrics seems to be a guaranteed improvement in terms of enhancing security and increasing work speed, two of the biggest traits required for development. Hence, investing in this technology seems to be the forte of many private firms and government agencies especially the secret services like CIA of USA or R&AW of India.

Apart from these rising trends, numerous more developments that are pursued which might be part of future trends include the voice printing and heartbeat authentication.

Institutions are using frequency estimations, neural networks and Gaussian mixture models to process and store voiceprints. This system focuses on the speaking aspect of the individual and therefore applicable in the fields of kidnapping, ransom demands and crank phone calls.

Companies illustrating exceeding innovations are using one-step verification using heartbeat authentication. This technique is applicable as wearable wristbands, which checks a person’s exclusive electrocardiograph, making false identification very hard.


Biometric technology presently represents the safest procedure as far as online security is concerned. The innovative method has a large scale following and with the way things are going this system seems just the right one to follow. However, the hackers are also showing innovations in their fields and a recent example of that is the hacking group called Chaos Computer Club who replicated the fingerprint of the German defense Minister. Therefore, how the security firms encounter such lapses is to be seen in the future.


How A Fingerprint-Recognition Attendance System Works

download (11)A fingerprint-recognition system is a biometric technology system wherein attendance is guaranteed with a single scan of the fingers. In present days, not only is physical thievery a dangerous crime but with the onset of internet, identity thefts, credit card frauds are common thefts.

The use of biometric technology is on a rescue mission to counter these security threats. Biometrics not only ensures security but also guarantees a human that he/she can sleep well if their belongings are governed by this technology. A major application of biometrics that comes in handy in almost every institution be-it government or private is The Fingerprint-recognition Attendance System.

What is a fingerprint-recognition attendance system?

A Biometric device such as finger scanner consists of –

(a) A scanning device

(b) Software that converts scanned information into digital and compares match points

(c) A database that stores the biometric data for comparison

To prevent identity thefts, the data encrypts as soon as gathered. To convert the biometric input, a software application uses specific point identification of data as match points. These match points in the database process use an algorithm that translates that information into a numeric value. Then the database value compares the biometric input the end user has entered into the scanner and authentication is approved.

Here are three images to help understand the process.

Difference in the numerical and scanned values makes the system trustworthy and resourceful. Attendance system is used to track each and every person coming to your place who is actually the person he/she claims to be. It uses the fingerprints to verify the person’s identity and record his/her time-in and time-out.

Attendance Management System

Managing attendance records of students or employees of an institute is a dreary and tiresome task. To make the attendance related work automatic and on-line, the use of fingerprints could be highly valuable. This will first, save a lot of time and second, be environment friendly as paper use will be minimal.

Usually, attendance management falls under two categories namely Conventional and Automated methods.

Conventional methods include time sheets, attendance registers whereas automated methods include barcode system attendance, magnetic stripe attendance system, Radio Frequency Identification (RFID) and the biometric attendance system.

Benefits of fingerprint-recognition attendance system

  • Saves time, is accurate and is a reliable information source
  • User-friendly and easy to use
  • Enhances security to its fullest
  • Avoids proxy thumping as is highly famous with students
  • Can store up to 30,000 records which would be a bulk data otherwise
  • Easy to manage employees, departments and multiple shifts
  • Easy operations with touch keypad technology
  • Solves a bunch of time tracking issues


A fingerprint-recognition attendance system is an excellent advancement in the field of development as it increases our reliability and helps us gather piles of information which otherwise would have taken us a hell lot of time to collect. The technology can be hardly breached with fake fingerprints if such a system is to be used for attendance management and time-bookings.

However, take the fingerprint scanning to the bigger forum, it needs other Biometric enhancements like DNA sequences, facial patterns etc.

The government should use this technology in most schools and colleges in order to have a fair attendance record of students. As for the corporate sector, electronically or physically handled time-sheets must be replaced with a Fingerprint recognition attendance system which will help prosper the company better.


How to Get The Best From Your Monitor Calibrator

download (10)You’ve bought your monitor calibrator, installed and updated the software, connected the measurement instrument and you’re all ready to make your first display profile. Accurate on-screen color is just a click away.

Or is it?

Before calibrating and profiling a monitor for accurate color display, there are a number of ‘pre-flight’ checks you should carry out to ensure that the results you get are as good as possible.

Uniformity assessment: It’s not worth attempting to profile a display if it significantly fades at the corners or has a localised color cast, as any judgements you make will be affected by this. A quick way to visually test uniformity is to set a neutral mid-gray desktop pattern and close all windows. Older-style CRT displays usually have controls that allow you to adjust for mis-aligned screen display and various other screen geometry faults, but there isn’t anything you can do about a faulty LCD panel; be aware that LCD manufacturers do specify tolerances for uniformity and defective pixels.

Clean the screen and position the measuring device: LCD panels don’t attract dust the way electrostatically-charged CRTs did, but it still settles there, and fingerprints won’t help your calibration efforts either. Make sure that if you have a colorimeter with suckers for attaching to glass CRTs that you don’t press it against an LCD panel as it could pull the front membrane off when you remove it. All recent colorimeters for use with LCD displays ship with counterweight arrangements that allow the instrument to rest against the front panel. It usually helps if you tip the screen slightly backwards, to ensure that the colorimeter stays flush to the screen and doesn’t move during measurement.

Resolution and bit-depth settings: LCD panels are best run at their ‘native’ (maximum) resolutions. Most LCD displays support lower resolution modes for compatibility with older video cards, but it may interfere with color rendition as well as image sharpness if you run the display at lower settings. If you’re not certain whether you’re running at maximum, it’s a good idea to check this and that you’re running the display at maximum color (bit) depth – see your operating system help for how to do this, but you should have ‘millions’ of colours, 24- or 32-bit selected.

Display warm-up: It’s crucial that you let your display warm up before attempting to calibrate and profile it. Although CRTs were always known to require a warm-up period to stabilise, it is also true for LCD panels, though once warmed up they then remain more stable than CRTs. Allow at least half an hour.

Energy and screen savers: Disable anything that is likely to change or shut off your screen before beginning profiling. Most screen-saver timings are based on user input activity and won’t necessarily notice that a calibration application is running. Given the warm-up requirement even for LCD panel displays, it makes sense both for calibration purposes and for general working to disable anything that turns the screen off too quickly.

Ambient lighting: Changing the luminance (brightness) on a calibrated display to allow for changes in lighting conditions will invalidate your calibration. Aim to achieve consistent lighting instead. Some display calibration and profiling tools (and some displays) offer ambient light adjustment options that are intended to compensate for changes in the lighting environment. These should never be used.

Arrange things so that the display is the brightest object in your field of view but don’t work in a completely dark room; lighting levels similar to those that are comfortable for watching TV are appropriate. This will help increase the apparent contrast and reveal more shadow details in your images. A monitor hood (included with many high-end models) may be helpful here. When measuring your screen for calibration and profiling, do switch the lights off, draw blinds or curtains, etc, to minimise the chance of stray light getting into the measuring instrument and giving false readings.

Once everything’s set, go ahead and run your calibration and profiling software and enjoy the benefits of accurate color.

This article is based on Practical Colour Management for Photographers and Digital Image Makers, an e-book that’s full of detailed practical tips on how to ‘do’ color management on real computer displays to support high quality image editing. It includes tips on choosing and using colour-critical equipment and the optimum system software settings and working environment for reliable results.
