One of the major new features to Exchange in Exchange 2013 is data loss prevention. DLP aides your company in ensuring that sensitive data is not leaked from your organization. Exchange 2013 SP1 adds an improvement to DLP in a feature called DLP fingerprinting.
Document Fingerprinting expands DLP capability to enable you to identify standard forms used in your organization, and then have exchange recognize those forms are sensitive information. For example, you can create a fingerprint based off a blank tax form, and then detect all matching tax forms with sensitive content filled in.
To create a document fingerprint, simply upload a blank form, such as an intellectual property document, government form, or other standard form used in your organization. Once you have created a document fingerprint, it becomes part of the sensitive information types that you can use to customize your DLP policies. You can then create transport rules to detect documents that match a document fingerprint when users try sending them over email. This will allow you to apply DLP policies, like encrypting the document or providing a notification to the user via Policy Tips.
