Study Notes
Authentication Basics
- Authentication is divided into three categories: something you know, something you have, and something you are.
- Identification is the act of asserting who a person is, while authentication is the act of proving that asserted identity.
Biometric Authentication
- Biometric authentication uses biological properties, such as fingerprints, hand geometry, retina and iris scans, voice recognition, and facial features.
- Advantages of biometric authentication include:
- Cannot be lost, stolen, forgotten, or shared.
- Always available.
- Difficult to forge.
- Biometric authentication involves matching a template closely enough, with "close" being a system parameter that can be tuned.
Problems with Biometric Authentication
- Biometric recognition devices are costly, although costs are decreasing.
- Biometric use can be intrusive and culturally sensitive.
- Manual laborers may wear off their fingerprints over time, affecting recognition.
- Biometric readers can be a single point of failure.
- Variation in biometric readings reduces accuracy, leading to false positives and false negatives.
Token-Based Authentication
- Token-based authentication involves using a physical object in your possession, such as a key, badge, or identity card.
- Tokens can also have data to communicate invisibly, such as credit cards with magnetic stripes or embedded computer chips.
- Examples of token-based authentication include credit cards and access cards with passive or active wireless technology.
