Submission + - Wi-Fi Routers Can Scan Your Body to Identify Exactly Who You Are (futurism.com) 1

JoeyRox writes: New research out of Germany’s Karlsruhe Institute of Technology found that the types of Wi-Fi routers we all have in our homes come with a major privacy vulnerability that can be used to identify any human body that comes within their range.

The study, flagged by Gizmodo, used machine learning systems to identify individuals with an accuracy rate of 99.5 percent. To do so, the researchers exploited a vulnerability in a process known as beamforming feedback information (BFI), which was introduced to allow routers to focus Wi-Fi signals on connected devices, as opposed to the older approach, which is to blanket an entire area in coverage.

While BFI is great for network connectivity, it has a major downsides for privacy. For starters, devices connected to a router using beamforming need to send constant feedback in order to be found. As routers send out and receive network feedback, the signal is inevitably impacted by real world factors like pets, walls, and people.

Making matters worse is the fact that this data is basically wide open for anyone to grab — not only is that feedback data unencrypted, it can also be accessed without ever connecting directly to the router.

I'm sure you're familiar with the countdown protocol, all the pre-flight checks, etc. These power up a range of subsystems, motors, etc, so that everything can be verified prior to ignition itself. The complete sequence takes a very long time. Under normal flight conditions, you can't check for absolutely everything (instrumentation is mass, and mass is the enemy) but there's still a lot. However, during an engine test, you can pack a lot more sensors in.

This is where you'd want to be spotting loose connections, pumps that aren't quite even, pressures that aren't as steady as they should be, vibrations that shouldn't be there or do not match expectations, turbulent flows, and so on.

At ignition, it takes between 3-6 seconds to go from stopped to 90% thrust. For humans, that's near-instant. For a computer sensor that's operating a million samples per second, that's 3-6 million readings. A computer performing a billion calculations per second shouldn't have much difficulty in comparing 3 million readings against model predictions and determining if both the values themselves and the rate of change at each point such a sensor exists are all good. Emergency shutdowns during those first 3 seconds are perfectly viable.

Vibrations are the ones that are likely the most interesting, because those are likely to change before something breaks, not sure how fast you can make infrared sensors, but that's also an area where things are likely to alter before point of failure.

The evolutionary pattern was created because food was unreliable and energy demands were unpredictable - but high, due to the large brain. (Possibly larger than it is today, but there seems to be conflicting data there.)

Now, rationing extreme energy foods is certainly one option, but it's not a particularly satisfactory one as the energy demands vary by profession and by time within a profession. You simply can't predict what people will need and there's no way to standardise this.

There is a second option. Intense focus is impossible for beyond about 45-90 minutes at a stretch, or for more than 3-5 hours in a day. Meetings degrade intelligence, according to psychological research, so you want to minimise those. After about 7 hours, work will mostly have negative value. If you increase the amount of high physical activity for at least an hour a day (and potentially longer if the amount of soft work is minimal in the job) then you will improve physical fitness and general health, without having to substantially alter diet. However, that still only gets you so far, because a poor diet still impacts physical and mental health, and can lead to brain decline. (It's a big factor in poor brain health in children in schools.)

A third option, then, is to actually improve meal quality in schools and for workplaces to work with the food industry to provide cheaper/easier access to high quality foods that actually taste good, not merely sensible energy foods. This would seem to be target solution, with in-work exercise to supplement it.

Whilst that is perfectly true, it is questionable as to whether it is useful or necessary. If a rocket is being tested, then logically it should be heavily instrumented. If it's heavily instrumented, and the instruments are themselves competently designed, there is no obvious reason why the engine can't be auto-cut when problems start to arise. And they will have arisen long long before the explosion.

The values may have independently been "within permitted range", but if the pattern of those values doesn't make sense, then something has gone wrong. There may well also have been subsystems that were insufficiently instrumented.

"They're the experts" is often an irrelevancy - we lost TWO shuttles and crews to political decisions, when the experts on the ground were ignored. DeHavilland lost endless Comets to basically the same blunder, when political decisions by management over the reality of metal fatigue overrode analysis by actual experts. Improper monitoring and inadequate computer controls will be from a burden of costs and time (both political constraints, not engineering constraints). As, indeed, will improperly manufactured parts, improper software (anyone rememebr Arianne IV's mishap due to buggy software?), improperly-defined constraints, and inadequate quality controls.

The experts are usually either well aware of mistakes or afforded no means of detecting them.

I see no reason not to think this was anything other than a management blunder.

This raises a very important question. If the CIA are taking shortcuts and making assumptions about anything, we should not be making assumptions ourselves that the CIA aren't doing the same elsewhere. I am, however, still waiting for biolabs and WMDs to turn up in Iraq - something for which they appear to have ALSO taken one person's unsupported word for. They also ratted out their own officers in retaliation for questioning the existence of "yellowcake" (that turned out not to exist).

I'd be wary of claiming there was a pattern, but... They do seem awfully incompetent.

Why do you think the Dutch authorities are now blocking the acquisition of Solvinity by some US based firm? Solvinity manages the servers for the national identity provider scheme (DigiD).
Personally I don't think the government should be using 3rd party clouds for anything remotely critical. They have the scale to make running their own infrastructure worthwhile financially, and the know-how to run it effectively.

Submission + - I found a second vote.gov -- and it's registered to the White House

As_I_Please writes: The Drey Dossier reports that the National Design Studio, an office created by executive order and which reports only to the White House, has been building copies of federal agency websites like vote.gov, passports.gov, login.gov and others.

What [the National Design Studio] is doing is taking the parts of the federal government that touch you directly, your prescription, your voter registration, your passport, your federal login, out of the agencies that legally own them and rebuilding them on White House infrastructure. Vote.gov belongs to the Election Assistance Commission, and the studio built a copy. Passports belong to the State Department, and the studio is building a replacement this week. Login.gov belonged to GSA, and the studio’s guy runs it now.

Trump has said publicly that this infrastructure is for other presidents, and he is right about that. It is the one thing in this story I take him at his word on. The infrastructure outlasts him. Whoever wins in 2028 inherits the websites, the vendors, the data, and the hardware, sealed and waiting.

Pragmatic? The decision was made at the very last minute despite the grave risks having been pointed out months ago. No action was taken. Now they unnecessarily blocked the takeover instead of taking actual pragmatic action. Such as: offering Solvinity to let the acquisition go through, if they are willing to end the contract for this service early, and sell the servers that are already living in a Dutch government-owned data center to a new partner willing to operate them.
