Hiding Sensitive Data from Data Sets

B.

Federation pertains to authenticating systems between different organizations.

Out of the given options, Federation is the option that does not relate to the hiding of sensitive data from data sets.

Here's a detailed explanation of each of the options:

A. Obfuscation: It refers to the process of making data unclear or unintelligible to prevent unauthorized access. Obfuscation can be achieved through techniques such as data encryption, data masking, or data scrambling.

B. Federation: It refers to the process of joining multiple organizations or systems to form a single entity. Federation is often used in cloud computing environments where different cloud providers work together to provide a unified service.

C. Masking: It refers to the process of hiding specific data elements within a data set. Masking can be achieved through techniques such as data substitution or data redaction.

D. Anonymization: It refers to the process of removing personally identifiable information (PII) from a data set to protect the privacy of individuals. Anonymization can be achieved through techniques such as data de-identification or data perturbation.

In summary, while obfuscation, masking, and anonymization are all techniques used to hide sensitive data from data sets, federation is not directly related to data hiding but rather relates to the process of joining multiple organizations or systems.
