When you connect DataTrails to your Dropbox account we automatically create a small amount of additional metadata about your files each time they change, and record that information on an immutable ledger. Those files are now equipped with long-term integrity and the ability for anyone to instantly verify the provenance and authenticity of your digital content using our free no-need-to-sign-up tool, Instaproof. And best of all, you don’t need to change your workflows! You can continue to email your files around, or send them through your favorite transfer app, and wherever they end up their provenance will be verifiable.
