I'm pretty sure Google and other large networks also build 'shadow profiles' on users to figure out who they are, who they're connected to, etc. And I wonder if this shady profiling data should be available for users to download under e.g. GDPR. Because it sounds to me like it should, but isn't.

I recall someone asked the Zuckholebot about shadow profiles in one of those hearings, and he avoided answering the question... Something about "my team will get back to you on thay, Senator.".

What's the news story here? Tech companies file innumerable number of patents without implementing them to cover the space in case they get sued so they can retaliate. Realistically this patent wouldn't actually be useful in practice for the proposed application but would be useful if written carefully enough to countersue for unrelated applications of the tech.

I think what makes a little more sense is to see this as part of a moat-digging exercise.

Building a large user graph from scratch is the major impediment to someone coming along and challenging Facebook. This kind of thing is trying to head off alternative ways to build that user graph.

What? You're saying companies file patents on tech they don't intend on using so they don't get sued by patent trolls for their non-use of some other preexisting patent? That doesn't make sense on any level. And if you don't think such a thing would be useful to a company like this (if it could really be made to work) you aren't using your imagination properly.

There's an example of this happening in the 2018 book Bad Blood by John Carreyrou. A doctor gets the scoop on what Theranos is developing and files a patent loosely based on what they understand Theranos to be developing. The patent was filed with the sole intention of using it against Theranos in the future when they release their product.

This is really easy to do. At a hackathon in 2012 our team in just a few hours built tech that would detect who you were standing next to or walking past, all while your phone is in your pocket - we were trying to build a tool that would replace exchanging business cards at conferences.

Have you heard of Bump? They were doing something similar until they were acquired by Google: https://www.theverge.com/2013/9/16/4736860/bump-acquired-by-...

They're basically the Google Photos team, now. Have you seen the ads about face recognition and auto-sharing? They've been working on the problem of photo sharing ever since they figured out that people didn't want to share contact info with Bump, they wanted to share photos.

> What? You're saying companies file patents on tech they don't intend on using so they don't get sued by patent trolls for their non-use of some other preexisting patent? That doesn't make sense on any level. Why does that not make sense? This has been the case at every job I've worked withe patent filing incentives. You get a few thousand dollars for coming up with an idea and going through the motions of writing t…

Okay, I get that it adds value to the company. But what do you mean by defense? How is filing patents that you don't intend to produce so you can win legal battles any different from patent trolling?

The defensive aspect is for companies with real products.

Company A owns patents X, Y, Z. Company B owns patents M, N, O.

Company B sues company A that one of their products infringes on patent N. Company A countersues that 3 products of company B's infringes on X, Y, & Z.

That's the defensive aspect for company A. They won't instigate but they'll retaliate aggressively. This is known as the "nuclear option" as this strategy was employed during the Cold War - build up your offensive arsenal as a defensive measure to protect yourself against a first strike.

Plenty of examples during the smartphone patent wars[1] and perhaps this strategy isn't quite as successful as it once was.

For patent trolls having a large patent portfolio can increase the likelihood that you own a patent that the troll's patent is based on helping you with prior art claims. So having a large patent portfolio improves your defensiveness there. Additionally a large patent portfolio increases the value of your company because those patents are IP that have tangible value in the market; many tech companies choose not to monetize but frequently IP licenses can be bought/sold (or even the patents transferred) and mutual IP licensing is frequently part of lawsuit settlements so there's further value there. Since it's impossible to actually predict the value of almost any given patent in the future, having a large war chest improves your bargaining position/value of the patent portfolio.

I've always been floored that people leave their location services turned on by default. I have mine on for no more than a few minutes a month. I only turn it on when I'm in an unfamiliar location, don't have my bearings, and looking at the map alone isn't enough to help without GPS.

You are being downvoted for this thoroughly sensible comment. At times, HN voting patterns actually scare me. My location too stays off unless I actively require it, mostly then for navigation. Yes, like just about any kind of countermeasure against anything, this one may sometimes introduce a measure of inconvenience. That's fine with me. No free lunch etc. [Edit: As somewhat expected, this comment on downvotes is i…

A complaint about downvotes getting downvotes shouldn't "scare" you.

They are available for phones and laptops, e.g. https://www.amazon.com/gp/product/B07B66VZ97/

That's pretty nice. I'll have to see if I can find some designed for ThinkPads and Samsung phones.

Should work on all Laptops, not sure what's different about ThinkPads. Probably won't work on Samsung phones though.

This is partially the same community that thought these violations would be a good idea in the first place, as long as we get a bit of hamfisted curated content and adtech monetization. Of course some of the invested individuals still want to defend it. Maybe just to maintain the cognitive dissonance and assure ourselves what we're doing to people is okay. Expect to be unpopular, but that's fine--popular is not the s…

Thats a pretty bad analogy. Losing the privacy aspect of your location is not the same thing at all as saving a few bucks on a coffee.

by comparing the accelerometer and gyroscope readings of each phone, the data could identify when people were facing each other or walking together. More evidence we need far more privacy controls in mobile operating systems.

I'm sure you believe that corporations are evil and basically out to get you, but the vast majority of people doesn't. I think it's safe to assume that you're the outlier here.

Have you ever tried putting yourself in the shoes of people who leave their GPS on? Can you see how much better the user experience is? Can you understand why someone who never had a negative experience involving their location data might prefer to leave their GPS on?

I leave my GPS on all the time. I love going back in time and see where I was at any given time. I can download the data and correlate it with a bunch of other metrics I keep track on. If it wasn't free, I would pay for it.

I'm not floored that you turn your GPS off. I've met many people just like you. Some of them had traumatic experiences in the past, others generally don't think other people are trustworthy. I can respect that. Just don't assume it's the default sentiment, because it's not.

Here's an interesting survey about trust:

Jokes on them, I have electrical tape on my camera lens. Something I learned from Facebook's CEO, ironically.

Same, but I like gaff tape because it peels off easy and re-sticks well without leaving a gummy residue

I use my laptop camera every day. I have a neat little plastic thing that can be easily slid back and forth and I am happy with
