One technique for evaluating database security involves performing vulnerability assessments or penetration tests against the database. Testers attempt to find security vulnerabilities that could be used to defeat or bypass security controls, break into the database, compromise the system etc. Database administrators or information security administrators may for example use automated ...
The first single-database computational PIR scheme to achieve communication complexity less than was created in 1997 by Kushilevitz and Ostrovsky [3] and achieved communication complexity of for any , where is the number of bits in the database. The security of their scheme was based on the well-studied Quadratic residuosity problem.
The main disadvantage associated with column-level database encryption is speed, or a loss thereof. Encrypting separate columns with different unique keys in the same database can cause database performance to decrease, and additionally also decreases the speed at which the contents of the database can be indexed or searched.

This technique focuses on large databases and hides the identity of individual "inputs" who might have private data and privacy concerns, Federated learning is a machine learning technique that trains models across multiple distributed nodes. Each node houses a local, private dataset.
In the database: Database receives the SQL and applies rewrite to returned masked result set. Applicable for developers and database administrators, but not for applications (because connection pools, application caching and data-bus hide the application user identity from the database and can also cause application data corruption).
Formally, a "database" refers to a set of related data accessed through the use of a "database management system" (DBMS), which is an integrated set of computer software that allows users to interact with one or more databases and provides access to all of the data contained in the database (although restrictions may exist that limit access to particular data).
Database administration is the function of managing and maintaining database management systems (DBMS) software. Mainstream DBMS software such as Oracle, IBM Db2 and Microsoft SQL Server need ongoing management. As such, corporations that use DBMS software often hire specialized information technology personnel called database administrators or ...
A formal definition of ε-differential privacy. is a dataset without the privat The 2006 Cynthia Dwork, Frank McSherry, Kobbi Nissim, and Adam D. Smith article [3] introduced the concept of ε-differential privacy, a mathematical definition for the privacy loss associated with any data release drawn from a statistical database. [4]
