  • It sure is possible to embed invisible information into videos and images, it’s called metadata. Now you might think of other techniques, e.g. https://en.wikipedia.org/wiki/Steganography but most if not all are, AFAIK (and I won’t pretend I know the state of the art in the domain) if they are within the data itself (thus become data, not meta-data), e.g. a visible stamp in an image, are made to remain visible. Compression codecs are specifically targeting the visible or audible spectrum. One of the most basic way to “compress” lossy information (as opposed to lossless) is precisely to remove the ends of the spectrum that is not perceived by the average human audience.

    So… AFAICT it’s either visible and thus can be spotted (and thus can be removed, even if by adding a black mark over) or not visible but then most likely will be removed by basic compression codecs even without trying to do so.

    TL;DR: no and I wouldn’t be until I see this in the wild (not a research paper claimed it’s technically possible).

    When you generalize your position about your available time and technical knowledge as the limiting factor for everybody you are not saying it’s impossible for you, you’re saying it’s impossible for anybody and everybody. That’s the problem. It’s like saying “I don’t like this food” versus “It tastes bad!”. For you they are equivalent, for others they are totally different. I’m not saying you, or anybody else, should learn about self-hosting (federated) social platforms then set some up, what I’m rejecting instead is giving up pre-emptively on the behalf of others because it’s giving power back to BigTech.












  • Worthwhile yet tricky. Companies like OpenAI, Google, Meta, etc are full of experts in statistics and they have access to a lot of storage space. If use a service from those companies, say 4hrs per day between 7am and 9pm, at a certain frequency, e.g. 10 requests / hour, then suddenly, when you realize you actually do not trust them with your data, you do 10000 req/hr for 1hr then that’s a suspect pattern. Then might be able to rollback until before that “freak” event automatically. They might still present you as a user your data with the changes but not in their internal databases.

    So… I’m not saying it’s not a good idea, nor useful, but I bet doing it properly is hard. It’s probably MUCH harder than do a GDPR (or equivalent) take out request then deletion request AND avoiding all services that might leverage your data from these providers.



  • I don’t think that’s possible. I think streaming in practice (not in theory!) is nowadays monitoring everything you do with the content they provide. In fact you yourself blocked your own TV from accessing the Internet.

    Anyway I saw quite a few technical solutions (general purpose computers) but I didn’t see any service to then use those with. There are quite a few streaming services I would trust though, e.g. public services like Arte.TV or PBS (well… I did, not I’d be cautious) that can be accessed without an account.

    So it depends in the end of what kind of content you mean to stream. You don’t have to answer that specifically but… if it’s not something that is genuinely public, available on services like PeerTube but instead rely on surveillance capitalism, e.g. YouTube, Netflix, etc then I’d argue the kind of streaming itself you want is not compatible with your privacy requirements.

    Edit: I’m not streaming except public radio (specifically fip.fr that’s all) on my desktop. I just download the content I need what from whatever sources provide it DRM-free. It’s both a technical alternative and a healthier practice IMHO.
