Explanation of Solution

Use of verification system by a company:

Companies use the verification system in the following manner. They are mentioned below:

Fingerprint reader:

Fingerprint reader is also referred to as fingerprint scanner that scans or captures the fingerprint bends and indentations.

• Some companies use the fingerprint reader to provide the security to doors, systems, and software.
• Some fingerprint software are installed into a system, mobile phone, and so on to lock and unlock the system.

Face recognition system:

Face recognition system helps to capture the images of face.

• It compares with computer image. If the faces match, then the person or user is a legitimate person. Otherwise, the person or user is an unauthorized person.
• Some mobile devices use this type of verification to unlock the mobile.
• Some companies use this recognition system to provide the security to access the room.

Hand geometry system:

The hand geometry system helps to capture the hand shape and size.

• If it matches, then the user is a legitimate person. Otherwise, the person or user is an unauthorized person.
• It can be used in colleges, hospitals, daycare centers, and so on.
• This type of recognition is used for huge companies to track the timing and attendance of the employees.

Voice verification system:

Program Plan Intro

Biometric devices:

Biometric device is a device that helps to authenticate the identity of a person by translating the fingerprint into a digital code.

• The code that is given by a person for identification is compared with a digital code that is present in a computer, and it helps to check the behavioral and physical features of the devices.
• If a code matches with a computer code, then access to a computer is given to an individual.
• When it does not match, access to computer is not given to that individual.
