As a more flexible and effective access control mechanism in databases, fine-grained
access control (FGAC) has drawn considerable attention from industrial and research …

The fine-grained access control (FGAC) is important to Web applications. However, it can be
circumvented by indirect access such as inferring sensitive data from insensitive data. In the …

Fine-grained access control (FGAC) must be supported by relational databases to satisfy the
requirements of privacy preserving and Internet-based applications. Though much work on …

Fine Grained Access Control (FGAC) provides users the access to the non-confidential
database information while preventing unauthorized leakage of the confidential data. It …

Databases are increasingly being used to store information covered by heterogeneous
policies, which require support for access control with great flexibility. This has led to …

Recently, we have proposed a model-driven approach for enforcing fine-grained access
control (FGAC) policies when executing SQL queries. More concretely, we have defined a …

In this paper, we propose an observation-based fine grained access control (OFGAC)
mechanism where data are made accessible at various level of abstraction according to …

Current-day network applications require much more secure data storages than anticipated
before. With millions of anonymous users using same networking applications, security of …

In the context of a project in model-driven security that focuses on the development of model-
driven techniques for building secure data-centric (web) applications, we extend, in three …

Database access control is indispensable to information system security. As enterprises
expand their services to the Internet, it has been widely recognized that traditional relation …
