authentication[ə‚thent·ə′kā·shən] (communications) Security measure designed to protect a communications system against fraudulent transmissions and establish the authenticity of a message. authentication (security)The verification of the identity of a person orprocess. In a communication system, authentication verifiesthat messages really come from their stated source, like thesignature on a (paper) letter. The most common form ofauthentication is typing a user name (which may be widelyknown or easily guessable) and a corresponding password thatis presumed to be known only to the individual beingauthenticated. Another form of authentication isbiometrics.authentication(1) Verifying the integrity of a transmitted message. See message integrity, email authentication and MAC.
(2) Verifying the identity of a user logging into a network or computer. Passwords, digital certificates, smart cards and biometrics can be used to prove user identity (see below). Digital certificates can also be used to identify the network to the client. See digital certificate, identity management, identity metasystem, OpenID, human authentication, challenge/response, IP spoofing and CAPTCHA.
Four Levels of Proof
The four levels of proof follow in order of least secure to most secure. None of them are entirely foolproof, which is why two methods are widely used (see two-factor authentication).
1 - What You Know
Passwords only verify that somebody knows the correct combination of characters. The answer to a security question such as "what is the name of your grandmother?" is in the same category. Although more personal, almost any data can be researched on the Web. See password.
2 - What You Have
A private cryptographic key in the computer is far more secure than a password, and authentication tokens, such as a USB key, verify that there is a physical item in the user's possession. However, computers and USB tokens can be stolen. See challenge/response, digital signature, public key cryptography and authentication token.
3 - What You Are
Biometrics such as fingerprint and iris recognition are more difficult to forge, but these systems can be fooled. See biometrics.
4 - What You Do
Dynamic biometrics such as hand writing a signature and speaking a particular phrase are the most secure; however, replay attacks can fool the system.authentication
authentication Biometrics
The use of a personal feature—e.g., face, hand, fingerprint, signature, voice, iris, or other highly specific indicator—to verify a person’s identity, and restrict access to private information to authorised persons.
Informatics
Confirmation of a user's identity, generally through a user name and password.authentication Biometrics The use of a personal feature, eg, face, hand, fingerprint, signature, voice, iris, or other highly specific indicator to verify a person's identity, and restrict access to information to authorized persons; confirmation of a user's identity, generally through user name and password or biometric characteristics. See Biometrics. Cf Authorization. au·then·ti·ca·tion (aw-thenti-kāshŭn) Protocol to confirm the identify someone logged onto a computer. authentication (o-then″ti-kā′shŏn) In an electronic health record or other computer system, a security mechanism (such as a digital signature) that provides for a unique means of identifying a system user.Authentication
Related to Authentication: AuthentificationAuthenticationThe confirmation rendered by an officer of a court that a certified copy of a judgment is what it purports to be, an accurate duplicate of the original judgment. In the law of evidence, the act of establishing a statute, record, or other document, or a certified copy of such an instrument as genuine and official so that it can be used in a lawsuit to prove an issue in dispute. Self-authentication of particular categories of documents is provided by federal and state rules of evidence. A deed or conveyance that has been acknowledged by its signers before a Notary Public, a certified copy of a public record, or an official publication of the government are examples of self-authenticating documents. AUTHENTICATION, practice. An attestation made by a proper officer, by whichhe certifies that a record is in due form of law, and that the person whocertifies it is the officer appointed by law to do so.

And the said records andjudicial proceedings, authenticated as aforesaid, shall have such faith andcredit given to them, in every court within the United States, as they have,by law or usage, in the courts of the state from whence the said recordsare, or shall be taken."
4. The above act having provided only for one species of record, it wasnecessary to pass the Act of March 27, 1804, to provide for other cases. Bythis act it is enacted, Sec. 1.

7. By authentication is also understood whatever act is done either bythe party or some other person with a view of causing an instrument to beknown and identified as for example, the acknowledgment of a deed by thegrantor; the attesting a deed by witnesses. 2 Benth. on Ev. 449. Authentication
