Biometrics The process of using a person's unique physical characteristics to prove that person's identity. Commonly used are fingerprints, retinal patterns, and hand geometry. Encryption The process of encoding data with an algorithm so that it is unintelligible without the key. Used to protect data during transmission or while stored. Password A sequence of characters that is …
Which authentication method uses unique physical characteristics of a user to identify the correct user? Password. Tokens. PIN. Biometrics.
Jun 06, 2011 · There are three common factors used for authentication: Something you know (such as a password) Something you have (such as a smart card) Something you are (such as a fingerprint or other biometric method) Identification occurs when a user professes an identity (such as with a username), and authentication occurs when users prove their identity.

Biometric authentication A type of authentication that relies on the unique physical characteristics of individuals to verify their identity for secure access. Multifactor authentication A type of authentication that requires multiple authentication credentials to verify the user's identity for a login or other transaction.
Identification occurs when a user professes an identity (such as with a username), and authentication occurs when users prove their identity. For example, users are authenticated when they provide both their username and correct password.
Something You Are. Biometric methods provide the something you are factor of authentication. Some of the biometric methods that can be used are fingerprints, hand geometry, retinal or iris scans, handwriting, and voice analysis. Fingerprints and handprints are the most widely used biometric method in use today.
If you’re planning on taking the CompTIA Security+ exam, the (ISC)2 SSCP exam, or the (ISC)2 CISSP exam, you should understand the three factors of authentication. They are specifically referenced in the following objectives: 1 CompTIA Security+ (SY0-201) 2 #N#3.6 Summarize the various authentication models and identify the components of each#N# 3 CompTIA Security+ (SY0-301) 4 #N#5.2 Explain the fundamental concepts and best practices related to authentication, authorization and access control#N# 5 (ISC)2 SSCP 6 #N#Access Controls domain#N# 7 (ISC)2 CISSP 8 #N#Access Control domain
One of the first steps of access control is the identification and authentication of users. There are three common factors used for authentication: Identification occurs when a user professes an identity (such as with a username), and authentication occurs when users prove their identity.
The something you know factor is the most common factor used and can be a password or a simple personal identification number (PIN). However, it is also the easiest to beat.
The something you have factor refers to items such as smart cards or hand-held tokens. A smart card is a credit-card sized card that has an embedded certificate used to identify the holder. The user can insert the card into a smart card reader to authenticate the individual.
Multifactor authentication uses any two or more authentication factors. A key part of this is that the authentication factors must be in at least two of the categories. For example, using a smart card and a PIN is multifactor authentication since the two factors are something you have and something you know.
