You are correct, it is not based on SQUID. But, I think SQUID is technically a class of quantum magnetometer? Quantum magnetometry is pretty vague, since most high-end magnetometers use some sort of quantum mechanics. I think the term you&#

Right, magnetoencephalography has been known for some time. The ending of that paper is wild though with the weird ESP paranormal stuff, then I remembered that this is a CIA paper from the 70s...

Background noise is pretty random. A cardiac signal is pretty regular.

They require a shielded room to increase the SNR. SQUID sensors are sensitive enough to record cardiac signals at distance. The issue is SNR. What they are saying is that they produced a low noise sensor array and managed to increase the SN

So is cm resolution with satellite imagery, but the NRO does have those capabilities.

Magnetocardiography is a thing. The NRO has some insane capabilities, so I wouldn’t immediately discredit the idea that a magnetocardiographic scan of a large area is possible. It’s important to note that the individual was isolated by mile

I wish I could edit my original post, but I meant to switch the causality around. What I’d meant was, a paid digital marketplace will end up with some form of DRM. And furthermore, economic incentives will drive devices to implement some fo

Being a web app doesn’t mean shit. We already have DRM encrypted web content where the consuming device requires some attestation to decode. I.e. Widevine.

For music and movies, yes. Though with movies, you even have HDMI HDCP and DisplayPort DPCP to make it harder. For games though, the game binary is the media. Game console developers have been very successful at preventing pirating.

Xbox, post-360, has been very successful at doing so.

Which is the same as root-of-trust attestation. Which is better: - Having applications provide kernel-level software to provide attestation. - Or having the OS provide root-of-trust attestation, but also requiring signed binaries, and preve

And Steam implements its own DRM and takes 30% from game publishers. Also, they don't stop game developers from providing their own DRM which require root-of-trust, like CoD or BF6 which require Secure Boot.

I think it's more equivalent to when game consoles check the license on disc media. It used to be via hardware in the disc reader, then online license checking. And now it's fully digital, media and license. The fucked up part is

Steam is a bit different, since that originated as a PC digital marketplace before complete root-of-trust DRM from HW->bootloader->OS->SW. If anything, I would bet on a shift where Steam on Linux requires a signed OS like Windows S

There's still no proof that it was Trenchant, and there was no evidence on the device. It's unlikely that it will ever be identified as an attack from Trenchant. Trenchant/L3Harris is a supplier for Five Eyes, and any attribu

Right. I was talking about passenger safety. But sure, if you purposefully designed a vehicle that has poor pedestrian visibility and end up getting hit by that same vehicle due to that poor visibility, you shouldn't be surprised.

An engineer at Ford isn’t developing cars that actively harms passengers. If you develop weapons, physical or digital, don’t be surprised if you end up on the receiving end.
