C.4.5 Describe the interrelationship between privacy, identification and authentication
Privacy
Defined as the seclusion of information from others. In the context of the web this can relate to healthcare record, sensitive data from financial institutions, residential/geographic records, criminal justice investigations/proceedings. For such information it is essential to prevent unauthorized access.
Identification
Defined as the process of claiming to be one’s identity. This process is important for privacy and is required for authentication.
Authentication
Process of proving/confirming one’s identification. Most usually done through a username-password combination, but other methods such as two-factor authentication become more and more prominent on the web. A common form of two-factor authentication requires the user to enter a code received by SMS in addition to the conventional password.
