Explanation & Hint:
To ensure the confidentiality of information, the following three methods can be used effectively:
-
Data encryption: Data encryption involves converting information into a coded form that can only be read by someone who possesses the decryption key. It is a powerful technique to protect data from unauthorized access and maintain its confidentiality.
-
Two-factor authentication (2FA): Two-factor authentication requires users to provide two different forms of authentication before they can access a system or account. This added layer of security enhances confidentiality by ensuring that only authorized individuals can access the information.
-
Username ID and password: While not as strong as some other methods on their own, using a combination of a username ID and password is a common way to control access to information. However, for enhanced security, it’s often recommended to complement this with additional measures like 2FA or strong password policies.
These methods, when used appropriately and in combination where necessary, help maintain the confidentiality of sensitive information.
