How to understand biometric solutions and their workings

Any biometric product solutions in India seen employed at various organizations are recognized as a verification system that is based on the physical characteristics of a person. However, these public safety solutions can go much beyond simple thumbprint technology and use various other features like handwriting, face, palm, ear-lobe, retina, iris, vein, and voice. Every individual has a unique biometric print that is the basis of this technology to provide verification and access. Using these security solutions enables a more accurate means to provide application integrity than access cards or passwords.

The parameters used by biometric solutions

Biometric product solutions in India identify human characteristics using key parameters to identify a person. These public safety solutions are available in the market using five basic parameters based on different characteristics. Any of these systems follows the primary characteristic of universality. This universality means that the characteristic is common to all individuals, while their uniqueness separates each individual. These characteristics should also be able to resist aging or other variances over time. The final characteristic that is used by a biometric solution is that it needs to be easy to capture this characteristic for measurement.

Types of biometric solutions available

There is a range of biometric product solutions in India that access a person’s physical characteristics for identification. These public safety solutions focus on physical aspects like a fingerprint, hand geometry, facial recognition, iris scans, retinal scans, vascular patterns, and DNA of the individual. Simultaneously, the behavioral characteristics of an individual are captured by analyzing vocal behavior, signature dynamics, and measuring the time spacing of the typed words. Some of these biometric solutions can be combined into a single solution or be used with smart cards. This provides a better ability to protect and secure data from crime, false identities, and theft.

How do they work?

Any of the biometric product solutions in India operates in two modes. The first part is the verification process that compares the captured biometric data against an already present and stored template. This comparison verifies that the individual being scanned is the same as the person’s identity in the stored database. This process can be done in conjunction with various other options like cards, ID numbers, usernames, and more. The second part of the public safety solutions these biometrics provide is identification. The system works on this by comparing the captured biometric with its biometric database to identify an unknown individual.

Any of the biometric devices consist of a reader or scanner, software to convert the scanned information to a digital format, and an encrypted database for comparison of the captured data. The first use of any of the biometric product solutions in India results in an enrollment where the individual characteristics are stored in the database. Further uses of these public safety solutions scan the characteristic, remove the clutter and enhance the image, create a vector of the captured data, and compare the captured image with the one in the database and take necessary action.
