Remove Metadata such as scan date, image ID

[jetic83]

Is there a way to delete certain fields in the scans such as comments or scan date or filename? These metainformation can be considered as PHI, or as non-anonymized data.

Has anyone ever followed up on this issue because it would make anonymize-slide much more useful. As of now, the remaining PHI within the metadata are proving to be an issue.

It can be done. Examples from a PR:

fh.directories[1].entries[XMLPACKET].overwrite_entry(our_xmp) fh.directories[1].entries[IMAGE_DESCRIPTION].overwrite_entry(our_image_desc)

These overwrite the XMLPACKET and IMAGE_DESCRIPTION tags on directory #1. To delete, overwrite with safe values. Make sure to overwrite with a message the same length as the original otherwise the data might still be there.

@jetic83, @a-dev-walker: Within the EMPAIA project, we have now developed our own solution for anonymizing WSIs (in various formats) including all the sensitive metadata. This is currently available via Gitlab . The paper for this is currently in review, the preprint can already be viewed at arXiv.
