Privacy-Preserving Mechanism for Monitoring Sensitive Data

The warranty of privacy of a person's data is understood as the capacity of managing, altering, restricting or publishing for a group of individuals chosen by the person. The shared data can be sensitive revealing something private, which deserves protection when shared, e.g. Personal financial information. Among several computing services, there is much sensitive data without any privacy-preserving mechanism. This work presents a privacy-preserving mechanism, which guarantees the privacy of the data owner and the person who accesses the data. A cloud monitoring mechanism was developed for data that needs to have its access monitored with intrusion-detection scenarios available for the data owner. The proposed viability was evaluated through tests on the response time to access the monitored page, server overload and consumption of server resources through the prism of an application using the mechanism. Such mechanism presents itself as a viable solution due to its minimum impact on computing resources and as a solution to help monitoring sensitive data access.
