ENSURING PRECISE ACCESS CONTROLS FOR RELATIONAL DATA WITH PRIVACY PROTECTION

Microdata is any record that contains information about a single entity, such as a patient or a business. An access control mechanism (ACM) is used to prevent unauthorized individuals from accessing private data. In the absence of a Privacy Protection Mechanism (PPM), an authorized user may violate someone's privacy by sharing sensitive information, which may reveal that person's identify and attributes. In terms of who can view what information and how it is shared, a Privacy Preserving Mechanism (PPM) maintains privacy while also meeting the requirements for anonymity and diversity, including k-anonymity, l-diversity, and v-diversity. It accomplishes this through the use of suppression and generalization approaches. It has to do with the necessity for privacy in order to meet the k-anonymity, l-diversity, or v-diversity requirements. There are, however, access control rules that specify how roles can be selected. A constraint limits the level of uncertainty associated with each selection predicate.Access control architecture is constrained by how accurate it can be while yet ensuring privacy. It is the responsibility of many jobs to meet the accuracy standards.
