Cross-instance Padif analyses
The major novelty with this release is the possibility to perform Padif analyses which include not only documents from your own instance but also from other ProFID instances.
This feature will allow users to explore possibly related cases in other countries, empowering them to further their investigations by reaching out to their colleagues.
Disclosed data
As a preamble, it is already worth mentioning that the feature only discloses the strict minimum of metadata about documents and series to users of other instances:
- The document's sequential identifier, containing the document's creation year and a sequential number.
- The identifier and name of the series any of the documents belong to.
- The name and email of document creators and series managers. Those are disclosed so that users can contact the right person in case a document or a series is of particular interest.
In particular, users don't have access to any images related to documents from other instances. Any computation required to calculate the similarity between documents is done privately on the server.
Performing a cross-instance analysis
Not all Padif analyses can be configured with external instances.
The document set of that analysis must be dynamic, that is, rely on filters rather than hand-picked documents. It also must not have labels, series or services as filters, as those are instance-specific features of a document.
To start a cross-instance analysis, go to an existing Padif analysis and select the "External instances" action from the dropdown menu.

Then select from the list of available instances the one you want to include in the analysis. The number in parentheses shows you the number of documents that match the document set filters of the analysis in the other instance.

Once saved, it will take about 30 minutes or more until you see the result of the cross-instance analysis, depending on when the next run is scheduled, how many other analyses are in queue and how many documents and regions of interest the analysis has to be performed on.
For each external instance selected, you will see a new tab containing the usual Padif dendrogram, but with documents from the other instance listed, as well as their associated series.

Opting out
By default, all instances except for ProFID series (which does not hold documents, only series), can be included in cross-instance Padif analyses.
It is, however, possible to opt out of sharing by emailing us at support+profid@zakodium.com.
Opting out will prevent both other instances from using your data and yourself to use the data of any other instance.
Other Padif improvements
New ROI edition interface
The page to edit regions of interest (ROIs) for Padif analyses has been completely redesigned.
You can now work on all the ROIs at once instead of removing and adding them one by one. It works similarly to the page for editing anonymized regions when importing scans.
You can also choose the color of the ROIs, which was not possible before.

Status information
We added context on the state of a Padif analysis, so that you are aware when things are missing or in an errored state in the report:
- The number of documents included in the report.
- The time at which the last execution happened, or if the analysis is being currently executed.
- The list of documents which are part of the analysis but aren't in the report, along with the reason why.
- The number of regions of interest which are configured in the analysis but are not yet part of the report.

Performance improvements
The Padif analyses are computationally expensive, and it can take some time to generate the report.
We have audited the performance bottlenecks and made some improvements to fasten the process.
Security improvements
More minor security concerns have been fixed based on the second security audit. Notably, users are now required to set a password with at least 10 characters, and users can see feedback on the strength of the password they chose.

Bug fixes and minor improvements
Minor improvements
- The activation / deactivation of a Padif analysis now has to be confirmed to make the operation safer.
- We facilitated bug reports by providing a direct mailto link in error alerts.
- For admins, we added the ability to filter users by role.
- The scan import process was made more robust, handling the presence of a white crease at the top of the canvas.
- In the document suggestions tab, if the document's serial number matches with others in the database, provide basic information about those documents and a link to them.

Bug fixes
- We fixed an error which prevented labels from being renamed.
- We prevented ROIs which exist on the Padif analyses but are not in the report, to be selected in the report.
- We prevented the deletion of a document if it is a reference document of a Padif analysis.
- When viewing a document, the suggestion tab lists the Padif analyses in which the document is involved. We fixed a bug which made the list empty even when there were linked Padif analyses.
