The duplicate asset detection feature helps you find and manage visually similar images in your Acquia DAM site. It analyzes images based on their content (using pHash) and finds duplicates regardless of filename, file format such as JPG or PNG, image size, or edits such as minor cropping and color adjustments.
This feature is designed for administrators to help them maintain brand consistency, manage storage, and ensure that users can find the correct version of an asset.
Note
This feature is disabled by default and must be enabled by an administrator. For this release, duplicate detection only analyzes image assets.
Enabling duplicate detection
Before you can use the feature, you must enable it in the admin settings section of your site.
Navigate to the Admin app and select Features from the menu on the left.
Find Duplicate Detection in the Manage Assets section.
Enable the Duplicate Detection toggle.
When you enable this feature for the first time, the system performs a one-time scan of all existing images in your DAM. This process may take some time to complete. The administrator who enabled the feature receives an email notification when the initial scan is finished.
Permissions for duplicate detection
The Administrate duplicate assets permission is required to manage duplicates. This permission enables users to access the Manage duplicates page to review and delete assets in a duplicate set.
When the feature is enabled, this permission is automatically added to the global admin roles. To manually add this permission to other roles, edit them in the Roles section of the Admin app.
Note
Users with this permission can see all assets included in a duplicate set, regardless of their asset group permissions.
Accessing and managing duplicates
When the feature is enabled and you have the correct permission, you can access the review page.
Navigate to Activity > Uploads from the top menu.
On the Uploads page, click Manage duplicates.
The system displays the Duplicates page, which is organized into two tabs:
Review needed: A list of all duplicate sets that require your attention.
Review completed: A list of sets that you have already reviewed.
Important
A Duplicate Set is a group of two or more assets that the system has identified as visually identical.
Reviewing a duplicate set
From the Review needed tab, select a duplicate set to begin your review.
Analyze the set.
The review page displays all assets in the set as cards. The assets are sorted by their upload date. The most recent upload appears first.
Select the filename of the asset to open its Asset Digest page in a new tab, and view its details.
Additionally, you can select the expand icon on the card to open a larger preview.
For each asset, make the decision by using the buttons on the card:
To keep the asset, click Keep.
To delete the asset, click Delete.
When you mark an asset decision as Delete, the system does not delete the asset at this step.
Select the Complete review button at the bottom of the page.
Assets marked with the Delete decision are not deleted until you submit the review as complete. You are not required to delete any assets. You can choose to keep all of them to move the set to the Review completed tab.
Deleting or restoring assets from the Pending Delete queue
When you make the decision to delete an asset from a duplicate set, it is not immediately erased from the system. Instead, it follows a standard deletion process. After you complete review of duplicate assets, their status is changed to Pending delete and they are moved to the Pending Delete queue.
An administrator can delete or restore assets from the Pending Delete queue with the following steps:
Navigate to the Admin Dashboard.
In the Asset Related Task section, click Pending Delete.
On the Pending Delete page, do one of the following to delete or restore an asset:
To permanently delete the asset, click the Confirm Delete button in the row for the asset.
To restore the asset, click the Restore button in the row for the asset.
Assets in the Pending Delete queue still count toward the storage capacity of your site.

Reopening a reviewed set
Once a duplicate set is moved to the Review completed tab, it is not permanently closed. A set can be reopened and moved back to the Review needed tab for further action in two ways:
The system is designed to keep your duplicate sets up-to-date. If a user uploads a new image that is visually identical to a set you have already reviewed and completed, the system automatically reopens that set.
What happens: The previously completed duplicate set moves from the Review completed tab to the Review needed tab.
What you see: The newly uploaded asset is added to the set alongside the assets you previously chose to keep.
Action required: Review the set again to decide whether to keep or delete the newly added duplicate.
This feature ensures that as new content is added to your DAM, your duplicate sets remain current without the need to manually search for new potential duplicates.
You have the flexibility to revisit your past decisions at any time. If you realize that you made a mistake or need to change which assets you kept in a previously reviewed set, you can manually reopen it.
To manually reopen a set:
Navigate to the Duplicates page.
Select the Review completed tab to view the history of all the sets that you have finished reviewing.
Find and select the set you that you want to reopen.
Select the Reopen for review button at the bottom of the page.
The entire set is then moved back to the Review needed tab, allowing you to change your Keep or Delete decisions for any asset within that set.
Assets that are in the "Pending Delete" status will not be shown in the reopened duplicate set. To change your decision on these assets, select "Restore" from the pending delete queue in the admin app.
