Abstract
Conference Title: 2014 9th International Conference for Internet Technology and Secured Transactions (ICITST) Conference Start Date: 2014, Dec. 8 Conference End Date: 2014, Dec. 10 Conference Location: London, United Kingdom XML databases are widely used in many different areas. They are multi user systems and can store a huge amount of data. Sensitive and important data need to be protected and stored securely. We have developed a dynamic trust based access control for XML databases to improve the security level and prevent malicious transactions from both internal and external users. Our system tracks user history of errors and bad transactions and updates the access privileges depending on trust values. In this paper, we evaluate the use of trust based access control by measuring the real time cost. The experimental work is performed to test the access time with and without trust based access control and suggests that the approach, though costly is not prohibitively time consuming.
