Video evidence is relatively easy to fix, you just need camera ICs to cryptographically sign their outputs. If the image/video is tampered with (or even re-encoded) the signature won't match. As the private key is (hopefully!) stored securely in the hardware IC taking the photo/video, any generated images or videos can't be signed by such a private key.

Under the Dewey Decimal System, books on wood carving and river systems would not be placed together, nor would books on conflict resolution and gardening.
It's almost like they'd be placed with books on related topics instead. This Maori traditional system is... not good. Imagine a system where the books are sorted by which Catholic patron saint they fall under, or which greek god they best represent. The librarians even admit in the article that it's only practical if you're already well aware of Maori mythos, everyone else gets 'an opportunity to learn' (i.e. be completely lost).
You, the end user, don't have access to your camera's private key. Only the camera IC does. When your phone / SD card first receives the image/video it's already been signed by the hardware.
