HDLP content fingerprint tag and manual tag

Jump to solution

Hi Heroes,

My customer is asking me this question:

There has 2 files: A B, A has app-based content fingerprinting tag; file B has manual classification tag.

Then, if we transfer A, B via Web Post | Outlook Email | USB, will the tag still persists or tag loss?

 

To me, the answer is the tag for file A is lost, because the content fingerprinting tag is stored in memory and NTFS Extended Attributes, it's not embedded into the file; for file B is the tag is still there, because manual tag is embedded into the file and it wont be lost when we transfer the file.

 

Is my understanding correct? thanks in advance...!

Hello and thank you for posting here!

Based on your examples, I believe your understanding is correct. Manual Classifications are embedded into the metadata of the file which allows the classification to be persistent across systems. Content Fingerprinting on the other hand is stored in memory on the system where the DLP Agent is installed. One instance where the Content Fingerprint can be retained on a file is when the "Content Fingerprinting for Outlook" option is enabled in the Windows Client Configuration policy (found in the Content Tracking section). This allows the Content Fingerprint to be restored on email attachments on the recipient machine as long as they have the DLP Outlook Add-in enabled.
