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

That can be potentially even easier; if you have a few specks of dust on the camera and your tape leaks a bit of light, they would have a perfect pattern to detect your lens - the specks aren't moving and there will be only speck effects recognizable on any video frame they capture when they max out contrast.

I've come to believe that privacy "by design" is impossible in the hyper-connected age. There are too many vectors for tracking, linking, and de-anonymization and software in general is too insecure. The only solution to the privacy problem is legislation. My favorite idea is HIPAA type regulations for intimate personal data like audio, location, etc. Leak location data? That will be $10,000 per incident where an inc…

Look up how rarely HIPAA violations result in fines. Since 1996 when enacted the sum of fines is something like $78 million— and almost entirely to huge insurance companies and university hospitals. Just barely slaps on the wrist.

I usually come down on the libertarian side of things, but given the virtual monopoly by way of network effects, I do think some legislation for user derived data is necessary. These folk are not going to self regulate and waive potential revenue if they are not made to. I’d go so far as declare them “near utilities”.

> I’d go so far as declare them “near utilities” Plastic surgeons are bound by HIPAA. They do not provide essential services. Similarly, we can regulate social networks without ensconcing them into our society’s fabric as utilities.

Interestingly, though I’m loath to insinuate they are an authority on anything, the UN has declared Internet access and access to information and dissemination a basic human right. “[The UN] condemns unequivocally measures to intentionally prevent or disrupt access to or dissemination of information online”.

It appears they believe it’s close to being a utility, and I’d argue in a way it has become close enough to need oversight as such.

It is rather amazing that smartphone cameras are so feature packed, yet still lack a lens cover. Something as old as cameras themselves.

Old cameras didn't exactly fit in your pocket, and didn't have sapphire glass... Though I do think it would be nice to have a hardware (iris?) way to close off the camera. Some laptops have this, though I'm sad mine doesn't.

I'm not really sure if that's a scary facebook thing or merely just an inconvenient reality of the world we live in now. There's quite a few papers out on fingerprinting/identifying cameras from images taken with them using intrinsics (dust, scratches, slight offset of image sensor with respect to lens).

I'm not really sure if that's a scary facebook thing or merely just an inconvenient reality of the world we live in now. These aren't mutually exclusive. The reality of the world may just be acquiring more scary things, and ones that are created for profit.

Is something being created for profit scarier/worse? I'm personally far more concerned about government surveillance programs that I have no option but to participate in.

Gross. Oh well, another one for the already massive pile of unreasonably greasy facebook creeping. Massively parallel automated stalking. This shit needs to be regulated soon. A lot of the people being data-fucked are not actually people who have signed a EULA or anything, and it's getting more and more dubious that this is readily-available information "in the public square" that has no reasonable expectation of privacy. In my opinion at least, as if that's worth anything.

Also forgive me if I don't 100% take their word for it that none of this shit has been implemented except a few tests in 2015. These companies are never forthcoming with the truth around these matters of privacy and security. Ever. Any breach, any shady practice is denied until it's not possible to deny anymore. Why should they be truthful? It can only bring bad PR and there has literally never been consequences for lying about it.
