<H3>PreciseID Fingerprinting</H3>
<DIV class=B-Body>One of the ways that you can classify data in your organization is by “fingerprinting” </A>it using the Websense patented PreciseID™ technology. (Other ways include identifying key phrases, regular expression patterns, dictionaries, or file types.)</DIV>
<DIV class=B-Body>&nbsp;</DIV>
<DIV class=B-Body>The power of PreciseID techniques is its ability to detect sensitive information despite </A>manipulation, reformatting, or other modification. Fingerprints enable the protection of whole or partial documents, antecedents, and derivative versions of the protected information, as well as snippets of the protected information whether cut and pasted or retyped.</DIV>
<DIV class=B-Body>&nbsp;</DIV>
<DIV class=B-Body>PreciseID technology can fingerprint 2 types of data: structured and unstructured. </DIV>
<DIV class=B-Body>&nbsp;</DIV>
<DIV class=B-Body></A></DIV>* Structured fingerprinting defines what tables and what data inside the table should </A>be fingerprinted. (To set this up, select <STRONG><SPAN class=B-Bold>Main &gt; Policy Management &gt; Content </SPAN><SPAN class=B-Bold>Classifiers &gt; PreciseID Fingerprinting - Database Records</SPAN></STRONG>.) 
<DIV></DIV></TD></TR></TBODY></TABLE>
<DIV></DIV>* Unstructured fingerprinting defines files and folders that should be fingerprinted. </A>(To set this up, select <SPAN class=B-Bold><STRONG>PreciseID Fingerprinting - Files &amp; Directories</STRONG></SPAN>.) 
<DIV></DIV></TD></TR></TBODY></TABLE>
<DIV></DIV>
<DIV class=B-Body>PreciseID classifiers not only define what to fingerprint, but when and how often to </A>run the fingerprinting scan. That way, if files or data change after fingerprinting, Data Security stays up to date.</DIV>
<DIV class=B-Body>&nbsp;</DIV>
<DIV class=B-Body>At scan time, PreciseID technology examines the content of documents or raw data </A>and extracts a set of mathematical descriptors or “information fingerprints.” These fingerprints are compact and describe the underlying content. By assigning unique identities to each information asset, PreciseID technology can track information in motion with great precision. Original content cannot be recreated or reverse engineered from the PreciseID information fingerprint.</DIV>
