Pros and Cons of Biometrics:


Biometrics is the technology which is used to measure and analyse human characteristics which include fingerprints,Irises, facial recognition, DNA, etc.
A unique aspect of identifying features for security purposes than that of a normal password or security codes is done by biometrics.

Pros and Cons of Biometrics:

Biometrics are very much now in the market because it identifies a person’s identity which is extremely hard to replicate.

  • It provides all the services according to convenience. It makes the password strong and complex.
  • They are stable and enduring. It can identify a person in spite of small variations.
  • Strong authentication and accountability which cannot reprobate.
  • It requires very less database memory and small storage.
  • It provides safety and are non- transferable.
  • It takes very less time to scan a fingerprint.
  • It also recognizes distinct characteristics.
  • It is very easy to operate and most people are familiar with this technology.
  • The iris scanners are well protected.
  • The iris is kept stable usually even decades.
  • Each iris has a specific pattern .
  • The voice recognition is very reliable .
  • It is very easy to use and very safe.
  • It is very difficult for another person to forge as it is well protected and make sure it doesn’t get spammed.
  • The keystroke is the most relevant technology available today .
  • It is very quick to operate.
  • It is impossible for another person to copy by observing somebody type.
  • There is no user interface.

The biggest cons of biometrics is that it is considered as invasive and people don’t feel comfortable giving out their personal details.
Specific cons for each biometric system goes as follows:

  • The major challenge is the process of biometric is that it is captured and mapped to an identity.
  • There is lack of accuracy which can lead to failure of the biometric system.
  • Privacy is the biggest issue of the biometric solution.
  • If once the information is hacked, it can lead to many serious consequences.
  • At times error in biometric devices appear like false rejection and acceptance.
  • It is due to inability to read the distinct characteristics of an individual.
  • It is a circumstance where the device rejects an user who is an authorized person
  • It is expensive and involves cost in getting the system up and running and the maintenance.
  • Integration is another issue which is complex and makes the technology’s invasive.
  • Acceptance of an authorized person is also a challenge when an individual feel uncomfortable.
  • At times , it causes injury to the fingerprint during the verification process.
  • The technology can also be used to replicate and stealing a persons identity.
  • They are very expensive as it costs much to set up a system.
  • A fairly short distance has to be kept by a person to get the exact reading.
  • An individual’s voice can also be copied.
  • It covers a large amount of storage when it comes to various patterns.
  • An authorized person must know how to operate the keyboard to get the exact analysis of the pattern.
  • False identity can occur if the algorithm used is incorrect.

The biometric technology is used by military bases, airports and also by large firms.
These devices which are mostly used in the current scenario are facial scanners , door locks , hard drives and more.

How to use Biometrics Access System:

Check your system before turnout:

Make sure that the it detects the correct physical characteristics.
Install the necessary equipment’s and test the devices before hand.

Spread information about usage:

Give the correct information and the guidelines to ensure the workers to use properly.

Comprehensive security plan:

Include biometrics with other necessary mechanisms like alarms, motion sensors and video surveillance.

Backup plan:

If there is malfunction while accessing biometrics , add on some more measures which can secure the system through PIN and passcodes.


Biometrics have additional aspects to keep an individual’s personal information private.
A certificate can also be used to authenticate identity.
Before implementation for a single factor authentication , make sure you understand all the legal information and other risk factors.
Biometrics are ways to use and also ensures customer satisfaction.

Future in the field of biometrics:

Security and customer satisfaction is the most important aspect which biometrics focuses on.It will become a revolution in the future and will set up a mark for the people to access this system for there security.
This will extend further to developing cities and other ecological systems.

New innovations and modern methods have shaped the technology.
It will be available for both enterprises and customer services which will include fingerprint face and iris scanning.

They have started to expand this system in medical fields all over the world.

The Aadhar program in India has brought this system to over a billion citizens to use this system.
Biometrics are going corporate in the future.
They are also finding new ways to authentic and access systems.
It is improving its accessibility and other necessary innovations.

Government agencies are increasingly using biometrics systems in variety.
Data privacy is a broad topic that pertains to technology and policy.
Biometrics uses are vast and beneficial for all the commercial organisation.
It is now turning to use identification and also for other purposes.

Introduction of multi modal biometric will be extended by many terms.
This technology confronts realistic performance.
Authentication is reasonable to expect and will contain some more form of biometric data.
It also allows a comparison with stored data in documentation.

Biometrics will certainly gain increased acceptance in all kinds .
It will also include new quality to security solutions .
Biometric authentication in the economic sector will reduce the need for physical objects like cards.
There will be two developments in response to this situation which are the attitude of people and the development.

The biometric mechanisms will make the operations easier and convincing.
They will also include body shape recognition, investigation of body parts , analysis of electrical and other fields and face and head vibrations during speaking.

In conclusion , biometrics is being more advanced with the upcoming technologies with its both negative and positive aspects.
It can lead us to a comparatively security solution.
