The difference between Verification and Identification

Identification recognition system

The recognition system is different from the verification system because the recognition system attempts to identify unknown people or unknown biometrics. The system attempts to answer the following question: "who is this person?" Or "who generated this biometric identification code?" And the biometric information provided must be checked against all other information already in the database. The recognition system is described as a 1-to-n matching system, where n is the total number of biometrics in the database.

Example

Forensic databases used by governments to identify potential fingerprints or DNA abandoned at a crime scene are often used as identification systems.

Verification verification system

The verification system tries to answer the following question: "is this the person they're talking about?" Under the verification system, individuals present themselves as specific people. The system checks the biometrics against the biometric files that already exist in the database linked to the person's file to find a match.

A verification system is often described as an one-to-one matching system because it attempts to match the biometrics provided by individuals with specific biometrics that have been archived.

Example

When passing the ETC, the detector will detect your license plate number and pop up the owner's information, and then the staff will have to check whether you look like the owner or not, which is the matching problem at 1:1.

Your phone has a face recognition function, which inputs the owner's facial information. The next time someone uses your phone, the phone will judge whether the current person and your owner are the same person.

During the airport security check, the inspected personnel holding ID cards and other documents, through the inspection channel, while recognizing the appearance and ID card information of the examined personnel, this process is a typical 1:1 face recognition.
