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.

∙ 9y agoThe most important disadvantage of using biometric devices to authenticate someone is lack of flexibility in conditions. There are many factors which could make identification difficult with biometric devices; such as injury to or loss of a finger, laryngitis, and background noise.

What characteristic makes some metals important in electronic devices?
They are conductors
Why was the discovery of the battery so important?
it allowed portable electronic devices to be made
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.
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 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?
biometric authentication device digital camera
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.

Which authentication methods support biometric security devices?
EAP
What alternative input device measures biometric identifiers?
Iris scanners and fingerprint scanners are alternative (biometric) input devices for computers.
Which two devices are consider input devices?
Keyboard, Bar-code Reader, biometric authentication device
What are some Technical terms for a biometric device?
Biometric devices measure (metric) features of living things (bio). To be useful in security (such as authentication and identification), biometric devices measure features of living things that are unique for any individual, such as the Fingerprint Readers now available on most laptops. Other biometric devices include Voice Print Analyzers, Facial Recognition Scanners, and eye (retina or iris) scanners.
Is a biometric device a input or output device?
Most biometric devices would be input devices although they may also utilize storage devices and output devices in their functioning. A biometric device usually takes in biometric information about a person and compares it to information stored in a database - much like username/password methods of authentication compare the username and password to the stored information for a user. Fingerprint scanners, read the fingerprint, convert it to a data stream and then compare it to the stored data previously recorded for the individual, retinal scanners read information about the retinal patterns of a user, convert it to data and compare it to stored data, etc. Note that biometric devices must rely on a storage device, but usually the storage device is not part of the biometric device. Instances of OUTPUT associated with a biometric device might be a signal to open a door or trigger an alarm, but again, the output usually comes from another device that the biometric device is connected to.
Does the use of a biometric device does not eliminate security and privacy?
The influence of biometric devices on either security or privacy will depend upon how they are used. Like any other device, biometric devices can be used appropriately or inappropriately. Does the use of a knife make you bleed to death? But then, maybe you will just chop vegetables.
