Penn State's QFilter puts security in XML database queries
New software developed at Penn State University promises to protect XML database queries and filter out unauthorized requests, thereby boosting query performance as many as 100 times, researchers said. QFilter, created by PSU School of Information assistant professor Dongwon Lee and three others at the university, can bypass the typical access control modules built into individual databases for security. The software can be deployed with off-the-shelf databases without requiring substantial changes to them, according to Lee.
