An improved data leakage detection system in a cloud computing environment. {Unpublished Master's Thesis }' Federal University of Technology, Owerri.https://repository.futo.edu.ng/handle/20.500.14562/2262Master’s thesis on "data leakage detection system". It contains pictures, diagrams and tables.An Improved Data Leakage Detection System is designed to mitigate the leakage of crucial and sensitive data in a cloud computing environment. Generally, leakage of data in computing system has caused a lot of irreparable damage or catastrophe to various institutions and organisations worldwide. Therefore, this research aims at detecting and preventing any intentional or non-intentional data leakages using dynamic password for data security. To achieve this the Object Oriented Analysis and Design Methodology (OOADM) was adopted. The new system was implemented using ASP.net MVC and Microsoft SQL Server Management Studio as the backend. And by incorporating an Audit trail/Transaction log mechanism, the new system monitors the activities within and outside the computing environment with date and time stamp. Hence, the system can be applied in any environment for the prevention and detection of any data leakage.enAttribution-NonCommercial-ShareAlike 4.0 InternationalData leakageaudit trailtransaction logwatermarkingperturbationdepartment of computer scienceMaster’s Thesis
