Final answer:
Authentication is about verifying user identities and ensuring data or message validity, often achieved through passwords, biometric data, or security tokens, while data integrity involves mechanisms like checksums and digital signatures.
Step-by-step explanation:
Authentication is concerned with the proper verification of the identity of users and the validity of messages or data. In computing, ensuring that a person or entity is who or what it claims to be is crucial for maintaining system security. This typically involves a combination of factors like passwords, biometric data, or security tokens. Moreover, data integrity measures ensure that a message or data has not been altered during transmission. Mechanisms such as checksums, cryptographic hashes, and digital signatures are commonly deployed to provide this level of assurance. Understanding these security principles is vital for protecting information in our increasingly digital world.
Computer Security is concerned with the proper verification of the identity of users and the validity of messages or data. It focuses on implementing measures to prevent unauthorized access, data breaches, and other security threats. One example of computer security is the use of password authentication to verify the identity of users before granting access to a system or application. Another example is the use of digital signatures to ensure the integrity and authenticity of messages or data.
