What is biometrics?
Let us start by understanding control de acceso biometrico the word “biometrics” first. Biometrics includes human characteristics or traits that can be employed as identifiers for granting access and control to a specific set of humans. The technology is gaining popularity ever since its inception and already appears to be ready to overtake manual access and control systems. Biometrics has a clear advantage over manual control systems as its functioning is always accurate and unbiased unlike the latter which is prone to discrepancies.
A typical biometric system must contain an interface that helps in recording data, storage and software that compares the entries. The three components would be:
1. Sensor: Sensor is the interface that facilitates recording of data and is the first point of contact for humans. There are different kinds of sensors that sense finger impressions, voice impressions and other parameters which are crucial for these systems.
2. Storage: A computer can act as the storage where all the database and information is maintained.
3. Software to match parameters: Software does the trick of comparing parameters and matching them with existing data.
Principle and working of biometric systems:
Biometric systems work on the basic principle that each human has unique physical characteristics like finger prints and iris structure, and behavioral characteristics like voice structures. One or more of these parameters are recorded with a suitable interface and are later compiled to match with the existing records in the database. If the recorded data matches with the existing data, then the control is granted to the user otherwise not.
To sum up, it works in 3 stages:
Registration for the database:
Viable entries are registered in the database to form a list of humans that can be granted access to a certain feature. This stage involves recording of the essential information that can act as identifier when a person requests permission for access.
All the registered data is stored for the purpose of compiling and matching with the incoming data, which is requesting access from the system.
This is the final stage where existing records are matched with a new entry which is requesting access. If the data matches, request is granted.
That is all about the 3 stages of working of a biometric system. Let us take a look at the advantages of biometric systems.
Advantages of biometric systems:
1. They are more accurate, technically flawless.
2. They are much faster in operation as compared to manual systems.
3. These systems can handle thousands of useful entries and work upon them.
Given their advantages, biometric systems are in huge demand in corporate offices, hospitals, schools, workplaces and other places where there are number of humans trying to access control and features. Today, there are biometric attendance systems, biometric access systems and biometric security systems that come in quite handy in different organizations.
