What is the most important disadvantage of using biometric devices to authenticate a person for access to a system?
Error rates are a possible candidate for most important disadvantage, though to varying degrees depending upon the specific authentication method. Higher sensitivity authentication methods increase the likelihood of false rejection, whereas lower sensitivities increase the likelihood of false acceptance.
The error rate of any given biometric authentication device can be broken down into the following categories:
- False Acceptance Rate - FAR
- False Rejection Rate - FRR
- Failure To Enrol Rate - FTE/FER
Being erroneously denied access to your banking information might be preferable to erroneously allowing someone else access, but neither scenario is desirable. Few systems with less than a 1% error rate are currently in existence.
Providing multiple/backup authentication methods increases the likelihood of an exploit or vulnerability, compromising security by trading FER for FAR/FRR.
In short, False Negatives and False Positives are the most important disadvantages.

What are advantages of multiplexer using in electronics?
Instead of adding more wiring and more connections that may pose a reliability issue and increase the cost, we can use multiplexers to send data to many devices over fewer wires.
What is the differences between electronic and mechanical devices?
Electronics Devices are those devices which are made from semiconductors like transistors fet mosfet amplifiers and ic's and other p-n junction devices. while mechanical devices are those devices which follow the mechanical principle such as strain gauge , machines and robot etc.
What are the Examples of hybrid devices?
Hybrid devices are combination of two devices with unique characteristics. for example::--modem mobile phones are hybrid of camera, phones and media player.
What is the most important disadvantage of using biometric devices to authenticate a person to have acess to a system?
Some biometric systems can be fooled such as the fingerprint reader. others if you have and acadent or somthing it could change so it would be imposible to log in. and they have to be kept clean or the wont read.
Definition of authentication and biometric devices?
Authentication is the process of verifying an individual's claimed identity, usually by providing credentials like passwords or security tokens. Biometric devices use unique biological characteristics such as fingerprints, facial features, or iris patterns to authenticate and verify a person's identity.
Is the face recognition system an example of biometric device?
Althogh there there are better biometric devices, face recognition is an example of biometric device because it has to recognize your face to authenticate you to a facility.
What is biometric identification devices?
Biometric identification devices are security systems that use unique physical or behavioral characteristics, such as fingerprints, iris patterns, or facial recognition, to authenticate an individual's identity. These devices provide a more secure and convenient way to access sensitive information or restricted areas compared to traditional methods like passwords or ID cards.
What is the device called that is used to authenticate identity by tranalating a personal charartertics called?
The device used to authenticate identity by translating a personal characteristic is called a biometric scanner. Biometric scanners can analyze unique features such as fingerprints, facial recognition, iris patterns, or voiceprints to verify an individual's identity. These devices are commonly used in security systems, smartphones, and access control systems.
What are the Names of five biometric input devices?
Five biometric input devices include fingerprint scanners, iris recognition systems, facial recognition cameras, palm print readers, and voice recognition microphones. These devices capture unique biological characteristics to authenticate individuals for security and access control purposes. They are increasingly used in various applications, including smartphones, security systems, and time-tracking solutions.
Bio metric devices?
Biometric devices are electronic tools that use unique physical or behavioral characteristics, such as fingerprints or retina scans, to authenticate individuals' identities. They are commonly used for security purposes in access control systems, time and attendance tracking, and in mobile devices for user authentication. Biometric devices offer an efficient and secure way to verify identity without the need for passwords or PINs.
What are Biometric devices used for?
A fingerprinting scan is a very common biometric device. There are also iris matching scanners for high tech security. @Nottingham YE$
Which two devices are considered input devices?

Where can you purchase biometric security?
Biometric security devices can be purchased from several different companies. Some companies that manufacture biometric security devices are Quick Access, Sentry Safe, Viking, Lock Safe, and Gun Vault.
What is biometric login?
Biometric login is a security feature that uses unique biological characteristics such as fingerprints, facial recognition, or iris scans to authenticate and grant access to a device or system. This method offers a more secure and convenient way to access devices compared to traditional password entry.
