Security systems with biometric capabilities are the pinnacle of security in the modern world. The word ‘biometrics’ has Greek roots, and literally means ‘life measurements’. These systems are top-of-the-line high-security options, and are very useful and high-functioning, especially for businesses, corporations, and facilities.
What is Biometrics?
Biometrics itself is the measurement of the physical, behavioral, or biological traits of an individual. These physical attributes can range from hair or eye color to fingerprints to tone or accent when speaking (vocal recognition). Therefore, biometric security systems are those that use these physical, biological, and behavioral characteristics to identify an individual and either grant or deny them access to a room or asset within a building.
Why Are These Systems Useful?
Though biometrics themselves have been around for almost 100 years, modern biometric security systems are highly advanced and very helpful when it comes to protecting buildings and the assets that lie within them, whether they be physical or digital. Since access is granted or denied based on individual features that are very difficult to recreate or change, the likelihood of an unauthorized person being granted access is much lower than it would be with a less elaborate system.
The Basics: 4 Main Components
A standard biometric system is comprised of 4 main components: the input interface, the processing unit, the data store, and the output interface:
- Input interface: These are the sensors that read human data (such as a fingerprint or an iris scanner) and convert it into digital data.
- Processing Unit: After the data from the sensors is converted into digital information, it is the job of the processing unit to, well, process it! This may include things like image enhancement, extraction of a specific feature, or comparison of the collected data with that which is stored in the database.
- Data Store: The processing unit pulls information from the data storage which is used to compare the collected sample to the one logged into the system.
- Output interface: This component communicates the decision, access granted or denied, to the rest of the system.
For example, let’s say you are attempting to enter Room A. You scan your fingerprint or iris on the input interface. The processing unit receives data from the data storage to help the system determine whether your scan matches one that has been programmed into the database for someone that has access to Room A. If your scan does match, the output interface will grant you access to Room A.
