Today's file sharing networks are creating potential security problems to enterprise networks, i.e., the leakage of confidential documents. In order to prevent such leakage, the authors propose the Data Leakage Prevention System (DLPS) which is applied at the entrance of the enterprise network to filter out the outgoing sensitive information. The DLPS is based on a content scanning engine which defines a new type of matching problem, called longest overlap matching which also exists in many other applications as a basic problem, such as the file detection in P2P content networks where contents are delivered by small blocks.
