How to Restore Deleted Provenance Data

October 25, 2026 5 min read

Restoring deleted provenance data means reconnecting an image whose C2PA metadata was stripped—by social media compression, legacy file editors, or metadata cleaning utilities—back to its original, cryptographically signed manifest. You cannot manually inject raw metadata back into altered pixels using tools like ExifTool, because changing even one byte invalidates the digital signature. Instead, provenance must be restored either by matching the asset against the Content Credentials Cloud registry using perceptual visual search, or by re-exporting the original master document.

Fast Fix

If the image was originally published using cloud storage, upload the stripped file directly to verify.contentauthenticity.org. The verification engine uses perceptual visual hashing to locate and link the file to its original cloud-hosted C2PA manifest. If the file was stored locally only, you must reopen the master .PSD and re-export via Export As with cloud storage enabled.

Why Traditional Metadata Restoration Tools Fail

Photoshop users often attempt to restore missing provenance by copying metadata from an untouched backup file to a stripped delivery file using standard EXIF editors.

This approach always fails with C2PA Content Credentials:

                                      │

[Modified / Stripped File] ◄── Injects Extracted Container

       ▼
[Validation Check] ──► Fails! "Tamper-Evident Alert: Hash Mismatch"

Content Credentials bind the manifest to the image’s unique pixel array using a SHA-256 cryptographic hash. If an image was re-compressed by a content delivery network or resized by a social platform, its pixel values changed. Copying an old manifest over altered pixels creates a signature mismatch, triggering a Fixing “Tamper-Evident” Alerts on Legitimate Edits warning.

Step-by-Step Restoration Methods

Method 1: Restoring Provenance via Visual Search

If you (or the original creator) exported the image with cloud publishing enabled, Adobe’s Content Authenticity registry maintains a visual hash of the file.

  1. Open your web browser and go to How to Verify an Image Using the Adobe Verify Website.
  2. Drag and drop the stripped image into the inspection box.
  3. If the local file lacks metadata, the viewer will automatically initiate an algorithmic visual search against the cloud database.
  4. When a match is detected, the portal displays:
    • Possible matches found in the Content Credentials cloud.
    • The complete timeline of authors, ingredients, and tool operations.
  5. Click Compare to verify that the matched cloud record matches your stripped asset.
  6. To prevent future stripping on web uploads, consult Troubleshooting “Provenance Not Found” in Social Media Uploads.

Method 2: Rebuilding Provenance from the Master Document

If the asset was only stored locally and the embedded metadata was scrubbed, you must regenerate the cryptographic package from the source file:

  1. Open the original master file (.PSD, .PSB, or .TIFF) in Photoshop.
  2. Go to Window > Content Credentials to inspect the existing session assertions.
  3. Review the history using How to View “Edit History” via the Content Credentials Panel.
  4. If the panel shows that credentials are active, select File > Export > Export As…
  5. In the right-hand panel, locate Content Credentials.
  6. Change the storage setting from Attach to files to Publish to Content Credentials cloud (or select Both).
  7. Complete the export. The newly exported asset is now permanently anchored in the public registry.

Method 3: Re-linking Broken Ingredients

If you are assembling a composite image and discover that an imported source graphic has lost its provenance:

  1. Locate the original camera file or authenticated source file for that graphic.
  2. In Photoshop, open your active project canvas.
  3. In the Layers panel, right-click the layer with missing provenance and select Replace Contents…
  4. Select the authenticated original file.
  5. Photoshop recalculates the ingredient assertion, replacing the “Unknown Asset” tag with the signed provenance of the source file.

Hard Stops: When Provenance Cannot Be Restored

Stop troubleshooting and accept that provenance is unrecoverable if:

  • The master project file was deleted, and the only remaining asset is a stripped JPEG/WebP that was never published to the Content Credentials cloud.
  • The original file was edited in an unsupported third-party tool, and the original author’s private signing key is inaccessible. C2PA manifests cannot be retroactively signed on behalf of another entity without their authorized digital certificate.
