The process of establishing the identity of a user or entity.
Definition
Authentication
The process of verifying the identity of a user or entity.
The Interrelationship
- Privacy and Authentication:
- Authentication helps protect privacy by ensuring that only authorized users can access sensitive information.
- Without strong authentication, unauthorized individuals could gain access to private data, compromising privacy.
- Identification and Authentication:
- Identification is the first step in the authentication process.
- A system must identify a user before it can authenticate them.
- Privacy and Identification:
- Identification can impact privacy if sensitive information (e.g., Social Security numbers) is used as an identifier.
- Using less sensitive identifiers, such as usernames, can help protect privacy.
- Identification: A user enters their username to claim their identity.
- Authentication: The user provides a password or biometric data to verify their identity.
- Privacy: Strong authentication ensures that only the authorized user can access their financial information, protecting their privacy.
Challenges and Considerations
- Balancing Security and Usability:
- Strong authentication methods, such as multi-factor authentication, enhance security but can be less convenient for users.
- Organizations must balance security with user experience.
- Data Minimization:
