Biometric security system are installed to provide high level security measure for restricting door access. Biometric security system uses various methods for authentication. Under this system, the information specific to an individual's body is used to ensure a high degree of security, which will make it difficult or rather impossible for a stranger to impersonate that person.
The biometric methods are used for personal authentication and door access security. There are several methods that exist for biometric identification. The technology utilizes features like face, hand shape, the voice, fingerprints, and the iris. Different types of biometric system uses different types of sensors to collect an image, either of a fingerprint, facial, or iris image. Using database of registered users, the images so collected are matched.

Factors For Assessing Usability

The major factors that are used for assessing usability are:

• How simple it is for the user
• What is the authentication speed
• What is the feeling of resistance
• What is the level of false-rejection rate

Factors for Assessing Security

The major factors that are considered for Assessing security are:

• Difficulty of forgery
• Swiftness in acquiring biological data
• Level of false-acceptance rate

Applications

Biometric method is used in following places to restrict door access:

• Lockers
• Safes
• Home
• Banks
• Small Offices
• Business Organizations
