Description

​

Biometric information refers to data or measurements that are based on an individual’s physical or behavioral characteristics, such as fingerprints, eyes, and voice. Biometric information is often used for authentication purposes as these biometric characteristics are unique to each individual and cannot be easily duplicated. Features like someone’s face, fingerprints, or tone of voice are both unique and inextricably linked to the individual. So, these features are an extremely secure way to verify the identity of a person.

How Does a Biometric System Work?

​

Fingerprints have long been used as a method of unique personal identification. Current day biometric techniques are merely an extension of that process. Biometric information is used in many other ways besides time keeping systems. It can be used to lock safes, digital accounts, and track criminal activity. Digital technology has created new and sophisticated ways to authenticate people with biometric systems.

From a functional standpoint, biometric systems require: 

​

• An input device that is physically present on-site. The device, typically scanners or cameras, captures the biometric information that needs to be authenticated.                                                                               

• A software system that can translate the biometric information and validate it against the person’s record. Image processing algorithms can do this extremely quickly and reliably.                                            

• A database of biometric information validation purposes. The database needs to be built before a biometric system can function. Each person’s biometric data must first be recorded then uploaded and attached to a record in the database.                                                                                                                  

Biometrics are already widely used to process entry in high-security locations, such as airports. That being said, biometric data isn’t just about security. It also makes life much more efficient for individuals. Facial recognition technology is built into, and widely used in, the majority of new smartphone models. And you can now even open your car door with just your fingerprint. Even if you forget your keys, there’s no chance you could leave your hand at home by mistake.
