Privacy Of Data Stream Using Sliding Window Method

Private Information - Personal information about an individual for which the individual can reasonably expect will not be made available

All of the examples above are ways a database can keep, retrieve, send and look for a precise data to another piece if the database system. Attributes have a big role in any database as makes the storage of information held stronger.

In addition, there are more personal data being collected as the cost of information technology falls. Although, collecting such data undeniably provides economic benefits, it has proved impossible to keep data completely protected against criminal misuse (Roberds and

45) ________ data represent the labels of multiple classes used to divide a variable into specific groups.

Metadata present a more complete picture of the data in the database than the data itself.

▪ Most attributes have a single value for each entity, such as a car only has one model, a student has only one ID number, an employee has only one data of birth. These attributes are called single-valued attributes.

Attribute Data - Data which on one of a set of discrete values such as pass or fail, yes or no.

Confidentiality: Ensures that data or an information system is accessed by only an authorized person (Techopedia, n.d.).

Information that is made accessible by the public unless intended. To reduce the risk of

Access control mechanisms protect sensitive information from unauthorized users. However, when sensitive information is shared and a Privacy Protection Mechanism (PPM) is not in place, an authorized user can still compromise the privacy of a person leading to identity disclosure. A PPM can use suppression and generalization of relational data to anonymize and satisfy privacy requirements, e.g., k-anonymity and l-diversity, against identity and attribute disclosure. However, privacy is achieved at the cost of precision of authorized information., we propose an accuracy-constrained privacy-preserving access control framework. The access control policies define selection predicates available to roles while the privacy requirement is to satisfy the k-anonymity or l-diversity. An additional constraint that needs to be satisfied by the PPM is the imprecision bound for each selection predicate. The techniques for workload-aware anonymization for selection predicates have been discussed in the literature. However, to the best of our knowledge, the problem of satisfying the accuracy constraints for multiple roles has not been studied before. In our formulation of the aforementioned problem, we propose heuristics for anonymization algorithms and show empirically that the proposed approach satisfies imprecision bounds for more permissions and has lower total imprecision than the current state of the art.

#17 organizationally unique identifier- the first 6 digits of an address which are used to indicate the vendor of the network interface.

If the primary key of a child entity contains all the attributes in a foreign key, the child entity is said to be "identifier dependent" on the parent entity, and the relationship is called an "identifying relationship." If any attributes in a foreign key do not belong to the child 's primary key,

3. Using your answer to Question 2, designate which attribute or attributes form the identifier for each entity type. Explain why you chose each identifier.

Identification is the row that defines the basic and grand view of what that project or vision will be in the end of last row of the framework. This part starts and states the grand scope of what will happen or what the end product will be. This row in the framework sets a starting point that the other part build off of.

Attribute: is a quality or object that we attribute to someone or something. For example, the scepter is an attribute of power and statehood.
