Owning an #NFT can be an investment or a way to support an artist or you buy something because you like it a lot. But once bought, your jpg, gif or movieclip is likely to remain hidden in your online inventory most of the time. But when buying a facefilter NFT you can actually use your purchased effect. You can view your augmented self with a smartphone app. But when altering your identity in this way, what you want is that others will see your altered identity. Thanks to the Snap Camera program it's now possible to activate these effects during a Zooms session. But once consumer AR glasses will hit the market, that's how other people are going to see your semi-digital appearance. The facefilter effects should be moving with you accross new devices and platforms.

But how to achieve that on current NFT markets? Today's visualisation tools and platforms might not be the ones we'll use in the future. So adding a link to the filter-effect on a specific platform, creates a dependency on that platform. What if it ceases to exist?

Packaging a whole filter effect into a file and offer it like the static jpg or movieclip content, would that be a way to guarantee the effect remains available? It moves the responsibility to the owner. Having the required technical skills, he/she could recreate the filter on a new platform based on the provided assets. But that also means that not only the current owner of the NFT, but also all the previous owners do have the components needed to create one or more versions of the effect. The uniqueness of the NFT is somehow lost.

So what's needed to put a facefilter for sale on a NFT marketplace? And is it possible to let them be available only to the current owner and no longer for previous owners? To achieve that situation the NFT's on this website have a build-in authorisation pattern. The code to unlock the filter can be found on the website. And it will only be provided to the visitor who currently owns the token, which will be verified by asking someone to login with the Metamask Chrome plugin installed so the ownership can be verified. This step in the verification process will be implemented soon, but for now the Snapcodes on the site can be used to check out the filters and see the authorisation procedure in action.
