Biometrics

Biometrics are forms of identification which rely on the physical characteristics of a person to prove who they are. Thumbprint scanners, retinal scanners, and voiceprint recognizers are all computerized forms of biometric authentication. Questions about these devices and other biometric techniques belong here.

Does a fingerprint portray authentication based upon something known?

User Avatar

Asked by Wiki User

Not always. Authentication is based upon one or more of the following:

  1. Something the user knows (such as a PIN).
  2. Something the user has (such as an ID card).
  3. Something the user is (such as a fingerprint).

Is a Biometric device an input output or storage device?

User Avatar

Asked by Wiki User

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.

How humidity effects computer?

Asked by Wiki User

Too little humidity is a low overall risk, though it can increase the amount of static electricity. Static electricity can damage semiconductors and cause premature failure.

Too much humidity can certainly cause premature failure. Lets suppose the manufacturing process of the chips is not perfect and water can condense inside. That would shorten the life of of components and even cause chips to get hot and crack. That is how popcorn pops. There is moisture inside the kernels of corn and when combined with heat, the moisture expands and causes the popcorn kernels to explode. The same principle can apply to computer parts.

Of course, other things can happen from too much humidity. The case can rust, contacts can corrode, contacts might not form good connections, and electricity can take routes other than intended. Such things in turn can cause unexpected behavior, instability, or even complete failure.

What is ICMPv6?

User Avatar

Asked by Wiki User

The Internet Control Message Protocol version 6 (ICMP v6) is a type of Internet protocol that deals with sending messages to other routers or computers.

ICMP v6 was developed because ICMP v4, its predecessor, was running out of IP addresses in its table of available IP addresses. This is due to more and more people around the world buying computers and connecting them to the Internet (most of these people live in LDCs [less developed countries]).

How are biometric fingerprint different from one another?

User Avatar

Asked by Wiki User

Biometric fingerprints are different from one another because fingerprints are different for each person, even with twins, so this is used as a unique identifier for each person.
