Theoretical Private Age Confirmation -- Possible?

Technology

  • Hello,

    I was gonna post this on Ask Lemmy, but then I thought maybe Technology would be a better fit for the theme. But then I saw it's mostly news, so I thought perhaps Ask Lemmy would indeed be a better fit. If this is not the case, please point me to the right direction.

    As a heads-up, I am not 'Murican, and never been to 'Murica, so keep that in mind.

    Seeing the recent news with France trying to age-restrict pornographic material online, I was wondering and have sort of an idea, that I wonder if it is actually doable and actually good.

    Hear me out: the gobermint likely already has your data, right? At least stuff like name, date of birth, etc. The gobirment could have a private and secure service, which websites and services could use to confirm certain requirements.

    For instance: A website wants to confirm if you're over 18. The website essentially asks the official gob. service, "is this user at least 18 years of age?". The official gob. service essentially has to answer "yes, your requirements are met" or "no, your requirements are not met", without giving away information on a person. The user gets prompted, being told what information is being required and whether they wish to share that. The official service wouldn't know where the request is coming from, but the original website requesting the information generates and shows a temporary code, which is not related to the website at all and is sent to the gob. service, so that the user can confirm it is indeed the website they were using that is requesting this, and not a hijack of some kind. The gob. service, if allowed by the user, sends out this confirmation to the original website, without the gob. service knowing the website and without the website knowing the user's info. The website then knows whether their requirements are met and can then act accordingly, such as by not allowing someone to access adult material if they do not meet the age requirement.

    Does this make sense? Is it doable? Could it be a potential private and secure way of confirming user information without either party having access to the other's information? Obviously, the idea could be worked on and polished, but as a starting point.

    Or validating source, making sure it isn't AI content which usually regurgitates the same talking points. Homogenizing the entire query and removing actual information variance of personal experience.

    I mean, the left has communities, but as soon a s they begin organising .worlders call them tankies.

    It’s funny how the article asks the question, but completely fails to answer it. About 15 years ago, Nvidia discovered there was a demand for compute in datacenters that could be met with powerful GPU’s, and they were quick to respond to it, and they had the resources to focus on it strongly, because of their huge success and high profitability in the GPU market. AMD also saw the market, and wanted to pursue it, but just over a decade ago where it began to clearly show the high potential for profitability, AMD was near bankrupt, and was very hard pressed to finance developments on GPU and compute in datacenters. AMD really tried the best they could, and was moderately successful from a technology perspective, but Nvidia already had a head start, and the proprietary development system CUDA was already an established standard that was very hard to penetrate. Intel simply fumbled the ball from start to finish. After a decade of trying to push ARM down from having the mobile crown by far, investing billions or actually the equivalent of ARM’s total revenue. They never managed to catch up to ARM despite they had the better production process at the time. This was the main focus of Intel, and Intel believed that GPU would never be more than a niche product. So when intel tried to compete on compute for datacenters, they tried to do it with X86 chips, One of their most bold efforts was to build a monstrosity of a cluster of Celeron chips, which of course performed laughably bad compared to Nvidia! Because as it turns out, the way forward at least for now, is indeed the massively parralel compute capability of a GPU, which Nvidia has refined for decades, only with (inferior) competition from AMD. But despite the lack of competition, Nvidia did not slow down, in fact with increased profits, they only grew bolder in their efforts. Making it even harder to catch up. Now AMD has had more money to compete for a while, and they do have some decent compute units, but Nvidia remains ahead and the CUDA problem is still there, so for AMD to really compete with Nvidia, they have to be better to attract customers. That’s a very tall order against Nvidia that simply seems to never stop progressing. So the only other option for AMD is to sell a bit cheaper. Which I suppose they have to. AMD and Intel were the obvious competitors, everybody else is coming from even further behind. But if I had to make a bet, it would be on Huawei. Huawei has some crazy good developers, and Trump is basically forcing them to figure it out themselves, because he is blocking Huawei and China in general from using both AMD and Nvidia AI chips. And the chips will probably be made by Chinese SMIC, because they are also prevented from using advanced production in the west, most notably TSMC. China will prevail, because it’s become a national project, of both prestige and necessity, and they have a massive talent mass and resources, so nothing can stop it now. IMO USA would clearly have been better off allowing China to use American chips. Now China will soon compete directly on both production and design too.
