Concept of Retina Scans for New Applicants

B.

This scenario is an example of authentication, which is the process of verifying the identity of a user or system. In this case, the regulation requires new applicants to provide a scan of their retinas, which is a biometric authentication method. Biometric authentication uses unique physical or behavioral characteristics, such as fingerprints, retinal scans, or facial recognition, to identify individuals.

Authentication is a crucial security measure used to ensure that only authorized individuals have access to resources, data, or systems. It helps to prevent unauthorized access, data breaches, and identity theft. By using biometric authentication methods, such as retinal scans, the likelihood of impersonation or identity fraud is significantly reduced.

Non-repudiation, on the other hand, is a concept that ensures that a user cannot deny or repudiate their actions or transactions. It is often achieved by using digital signatures or certificates. For example, if a user sends an email with a digital signature, they cannot later deny that they sent the email. Non-repudiation is more relevant in situations where there are legal or regulatory requirements to prove the authenticity of transactions or actions.

Integrity is the concept of ensuring that data or information is accurate, complete, and has not been tampered with. Integrity measures are used to prevent unauthorized modifications, deletions, or alterations of data. This concept is relevant when considering data privacy and security measures.

Accounting is the process of tracking and monitoring user activities, such as logins, accesses, or modifications. It is often used for auditing and compliance purposes, to ensure that users are following the appropriate policies and procedures. Accounting is more focused on keeping a record of actions performed rather than ensuring the authenticity of the user performing them.
