> Heck, a decade and a half ago there were claims that governments could narrow a search for an audio file upload based on the deviation from 60hz on the power line noise - in an audio recording. Wow. Any source for this?

I think it was referring to Electrical network frequency analysis, which is to find the time that the recording was made. It compares small changes in mains hum frequency to historic records of the changes. I am not sure how it is in the US, but the UK grid has a single frequency over the network so it wouldn't work for finding the location.

The propagation of waves is very fast, but wouldn't distance from multiple large sources or sinks fluctuate the frequency just slightly based on distance?

I wish more resources were spent on law enforcement at the local level, fighting real crime. They could have more police patrolling the streets and subways, deterring assaults[0] and daylight shootings[1]. Does anyone really care that this drug dealer is locked up? Is anyone safer now? Do I have to worry any less about getting mugged on the subway at night? Of course people are calling to defund the police, and if th…

Moving some money from the police into social services in your area is going to have a much more immediate positive effect on your life. The people mugging you in the subway need help/rehabilitation more than the police need another armored vehicle.

Legal or otherwise, I've seen plenty of sellers holding their products while photographing, so I wonder why it's done --- personally I think it looks a bit unprofessional to have a hand or other things showing. Putting it on a table or otherwise featureless surface would look far better to a prospective buyer.

It gives the impression you didn't just stock photo it or reuse someone else's.

nobody can read a comment with 6 repeated footnotes so close together, it’s insanely distracting. and they also start at 1. you type like an AI that does what you think the rest of us do.

There is considerable information back from the 80s to suggest that the US war on drugs was actually a system to enable racial discrimination. Then some years later, the ear on drugs became associated with the growth of the private prison industry and it's lobbyists. Indeed I provide no references here because it is quite an involved topic and difficult to prove given the publicly available information.

> There is considerable information ... that the US war on drugs was ... a system to enable racial discrimination. > I provide no references ... it is ... difficult to prove given the publicly available information These claims seem to strongly negate each other... to a degree that one detects the putrid scent of conspiracy theory.

Ah, yes, downvoted without responses.

To the downvoters: what would you call a strongly held belief that cannot be supported by documentary evidence; a problem you attribute to a coordinated effort to hide the actors and their intentions? Sounds an awful lot like a theory that there is a conspiracy.

What I find the most interesting about this article is that someone was able to be identified using a picture of their fingerprints. Thus, any photos posted online could be scoured for identification information. And with computer vision technologies becoming more mature, it means that regular video footage of people could identify them the same way in seconds or less using a wide variety of different visual traits.…

There was some pytorch software called "enhance", i.e. ./enhance [options] and you could take an image that someone took of their unpowered tv across the room and pull out a high resolution image of their face from the reflection in the matte-ish surface. I used it on reddit to convince people it was unsafe to post any images of that sort. It seemed to work for about 6 months. There's magic in image enhancement, but…

I'm curious about this photo-enhancement tool, because it's also a common joke in some circles that police procedural TV shows use "Zoom! Enhance!" when blurry photos -- or photos zoomed in until they're pixelated -- typically can't be enhanced for information-theoretic reasons. (Of course, if you can make assumptions about what the photo is of and what structure that thing would have, you can make relatively-likelihood estimates of different possibilities for the subject matter, such as different text strings in a blurry or pixelated photo of text.)

So, under some assumptions this typically shouldn't be able to work. :-)

That's called stylometry and it can be surprisingly accurate under the right conditions.

What’s the actual scientific evidence backing this? I’m asking because various forensic techniques that were previously perceived to be reliable (fingerprints, handwriting analysis, bite marks) turned out to be total bunk.

It's statistical analysis of word frequency, distribution, phrasing, and other features to create a fingerprint of someones writing style. I'm not sure what you mean by evidence, it's used to narrow a set of possibilities of authorship like a search filter.

I don't like to sound like I'm wearing tinfoil, but I'm not sure I believe this. We keep getting eyebrow-raising explanations for how computer criminals are caught; I always ask why bother? The American intelligence apparatus has compromised nearly all network traffic, from hardware backdoors on up. I assume the real way this person was detected and caught would be too embarrassing to admit, hence the fingerprints-fr…

Parallel Construction. it would be a national security catastrophe if it leaked that NSA was bulk decrypting all TLS/SSL traffic Internet-wide, by using a giant rainbow table of prime pair products for instant decryption without factoring, which was first proposed by Rabin back in 1997 at a NIST working group for establishing crypto standards. then NSA would lose the biggest SIGINT advantage since ENIGMA back in WW2.…

> by the way, i personally do believe NSA is doing this, and all of Tor is as good as plain text to Ft Meade, because Rabin's idea really would scale with today's computing and storage capacities, and because that is exactly what i would do too.

I love to talk about how we can mitigate attacks on cryptography as much as the next person, but have you looked at what algorithms Tor uses?

While they have a bunch of alarming legacy 1024-bit RSA and DH stuff, they also have Ed25519 identities and Curve25519 ECDH key exchange, plus running everything over TLS with various ciphersuites -- many of which are now ECDH.

https://github.com/torproject/torspec/blob/master/tor-spec.t...

The type of handshake and key exchange is chosen by the client, and I think the default has been to prefer the ntor method for a long time.
