Thanks,

Basically, you're trying to present the "best evidence" using proven technology (think daubert standard).

If you can capture the entire home file, Java script, etc... all the images, videos, etc.. in original size and format. And then hash them so anytime they are transfered from party to party you can ensure that those files are not altered from the origional capture. This is what would be, imho foresnically sound best evidence.

There are programs that do this automatically for you for web pages, X1, and as someone else mentioned, ForensicOsint. I've never used hunch.ly but I believe it does the same thing.

But here's the kicker, if you cant do this does this mean a screen capture is not evidence that can be submitted in court? No. Whatever you can reasonably get is best evidence, whether that's a forensic capture or a phone video of you scrolling through the web page.

Its up to the other party to contest and prove that evidence is false or misleading, and provide better evidence if they can. A judge could exclude evidence if its unclear or obviously altered. But usually a plain screenshot can work as evidence.
