Abstract
The present invention discloses methods for document-to-template matching for data-leak prevention (DLP), the methods including the steps of: providing a document as a stream of characters; splitting the stream into a plurality of serialized data lines; calculating a hash value for each serialized data line; checking for each hash value in a hash map of a template set; determining a similarity match to a particular template based on a predefined threshold of template hash values, of the template set, being found in the stream; and based on the similarity match, executing a DLP security policy for the document. Preferably, the template set is extracted from documents manually prepared by a security administrator. Preferably, each template in the template set is deduced automatically from a plurality of documents.
