How Photographers and Artists Can Keep a Dated Record of Original Files

Once a photo or illustration is online, it can be copied, cropped and reposted within hours. Before you publish, a dated record of your original file can help you show when that version existed.

What a dated record does

A timestamp records your file’s digital fingerprint (SHA-256) with a date and time. The fingerprint is calculated in your browser, so your original file is never uploaded. You get a shareable certificate showing the fingerprint and date.

What it doesn’t do

In Canada, copyright generally exists automatically when an original work is created. A timestamp doesn’t replace formal registration, doesn’t prove authorship by itself, and doesn’t stop anyone from copying your work. It is supporting evidence of when a file existed.

A workflow for visual creators

  1. Keep your originals: RAW files, layered PSD or Procreate files, and exports.
  2. Register the original before posting. Your first registration is free.
  3. Register big revisions separately, such as a final edit or a finished series.
  4. Post the web version, then keep the certificate with your project records.
  5. Keep your process files. Sketches, layers and metadata strengthen your story.

Useful habits

  • Keep original file names and metadata intact
  • Store originals in at least two places
  • Note shoot or creation dates in your own records
  • Use a visible credit or watermark on public versions
