Abstract

Distributed database security has become an important issue. In this paper, a new computational method for protecting the distributed databases is presented. Such approach is applied for protecting both textual and numerical data. This is done by adding only one hidden record with a secret function. For each attribute, the value of this function depends on the data stored in all other records. Therefore, this technique is more powerful against any attacks or modifications such as deleting or updating cell values. Furthermore, the problems associated with the work in literature are solved. For example, there is no need for additional storage area as required when adding additional columns especially with large databases. In addition, in case of protecting data by adding columns, we need to add a number of columns equal to the number of data types to be protected. Here, only one record is sufficient to protect all types of data. Another advantage is that, there is a possibility to use a different function for each field results in more robustness. Moreover, a real-time intrusion detection algorithm is introduced for fast attack detection. Finally, the proposed technique does not have any other requirements or restrictions on either database design or database administration.
