Protecting against Creative Commons revisions

Question

I am looking to purchase digital assets for a project.

The assets are loosely described as CC on the page:

You can use it for commercial purposes and make edits as much as you like. However cannot distribute. Credit isn't required.

I have tried contacting the owner to clarify however have gotten no response.

Two questions came to mind:

1: Can an artist revoke his Creative Commons Content

• No they can't - Ok, fine

2: How do you then prove that the paragraph on their website said what I quoted above at the time of purchase?

My honest solution would be to:

1. Setup a video camera pointing at my monitor

2. Navigate to google and google "todays date"

3. Navigate and load up the asset website - scroll to paragraph.

As silly as that sounds, I don't see another way.

Is the above solution valid?

Answer 1

Q: How do you prove that the paragraph on their website said what I quoted above at the time of purchase?

A: With something that has a provable and verifiable date stamp.

Although your video method is a viable solution, a simpler one to achieve the same objective would be to take a screenshot and save it in a way that preserves its metadata in case its veracity is ever questioned or contested in (for example) court.  If required, there are companies that can carry out digital-forensic examinations to the evidential standard to say if/when/how a file has been manipulated - and sometimes by who.

Another option is to use something like the Internet Archive's Wayback Machine to preserve the relevant web page (although not every site is included for various reasons given in the FAQ so you'll need to check).
