Copyright Proof - Frequently Asked Questions

How does this protect copyright?

Note that in most countries, you are already the copyright owner of any original work (literary or otherwise) that you have created, as soon as you record or publish it (whether or not you subsequently go through a formal registration process). By Digiproving your work, you are creating time-stamped evidence that you are the possessor of that content, which is the critical factor in ensuring you can prove your ownership (or someone else's plagiarism).

In some countries, you can go a step further by formally registering your copyright in your work as it is created/published or subsequently. There is usually a fee for this, and the benefits vary from country to country - in the U.S. for instance this should be done prior to instituting any legal proceedings for breach of copyright.

Digiproving your work is something that is done conveniently and will provide proof of ownership pre-dating any official copyright registration. Learn more at

Is my content uploaded to Digiprove?

Unless you (or your hosting provider) are using an old version of PHP (earlier than PHP 5.1.2) or you have specified otherwise, only the digital fingerprint of your content is uploaded, not the content itself. This allows you to protect private content on a private network using Wordpress. On the other hand, premium users have the option to upload content, which preserves your content independently of Wordpress.

I installed the plug-in and nothing seems to happen when I publish a new or edited post?

What's with the registration process?

Copyright Proof uses the Digiprove service, which needs to have the name of the person claiming copyright, and a valid email address to which Digiprove content certificates will be sent. Without this, there is no proof of ownership, so you might as well just have a simple copyright notice, there are a few plugins that will do this for you. To give effect to this, there is an "activation" step whereby you click on the link in an email we send you before your registration (and the plugin) become active.

Digiprove does not make use of these details except to deliver the service. Please read the terms of use (including privacy policy).

Your web-site appears to be commercial. Is this going to cost me anything?

Can I review my history of Digiproving online?

Yes, you can review your history online (and perform other functions) by visiting - you will need to log in using your Digiprove user id and password.

I get an error message: "invalid user id, domain, or api key"

Check your user id first; if that is correct, there is a problem with the API key and/or domain. Each API key is associated with a domain (e.g., or On initial installation, Copyright Proof will automatically assign one to you using the domain name recorded in the Wordpress "General" settings of your blog. If you change this domain name, or you want to set up the plugin to run in another blog, you can request a new api key for the new domain. The quickest way to do this is to go to Copyright Proof Settings page and tick the box entitled "Obtain new API key automatically" and press "Update Settings" (you will be asked for your password). Note that multiple domains under one user id is only permissible to subscribers. Free users are limited to one domain.

More detailed suggestions can be found at the Installation Troubleshooting page.

I get an error message: "daily limit of API requests exceeded - please upgrade Digiprove account"

If you are a free user getting this message, it means that you are attempting to do more than 30 Digiprove transactions in any given day, which is a maximum we have introduced for free users. Some users were going into the thousands. Higher limits apply to subscription accounts.

I'm a developer - how do I link directly to Digiprove API?

Use of the Digiprove API from other applications is free. The same limitations apply for the premium services as if you were using this plugin. Contact us at if you would like to know more. Details of the (Soap) API are found on our resources pages.
