Disabling Self-Driving Cars with a Traffic Cone

You can disable a self-driving car by putting a traffic cone on its hood:

The group got the idea for the conings by chance. The person claims a few of them walking together one night saw a cone on the hood of an AV, which appeared disabled. They weren’t sure at the time which came first; perhaps someone had placed the cone on the AV’s hood to signify it was disabled rather than the other way around. But, it gave them an idea, and when they tested it, they found that a cone on a hood renders the vehicles little more than a multi-ton hunk of useless metal. The group suspects the cone partially blocks the LIDAR detectors on the roof of the car, in much the same way that a human driver wouldn’t be able to safely drive with a cone on the hood. But there is no human inside to get out and simply remove the cone, so the car is stuck.

Delightfully low-tech.

Tracking Down a Suspect through Cell Phone Records

Interesting forensics in connection with a serial killer arrest:

Investigators went through phone records collected from both midtown Manhattan and the Massapequa Park area of Long Island—two areas connected to a “burner phone” they had tied to the killings. (In court, prosecutors later said the burner phone was identified via an email account used to “solicit and arrange for sexual activity.” The victims had all been Craigslist escorts, according to officials.)

They then narrowed records collected by cell towers to thousands, then to hundreds, and finally down to a handful of people who could match a suspect in the killings.

From there, authorities focused on people who lived in the area of the cell tower and also matched a physical description given by a witness who had seen the suspected killer.

In that narrowed pool, they searched for a connection to a green pickup truck that a witness had seen the suspect driving, the sources said.

Investigators eventually landed on Heuermann, who they say matched a witness’ physical description, lived close to the Long Island cell site and worked near the New York City cell sites that captured the other calls.

They also learned he had often driven a green pickup truck, registered to his brother, officials said. But they needed more than just circumstantial evidence.

Investigators were able to obtain DNA from an immediate family member and send it to a specialized lab, sources said. According to the lab report, Heuermann’s family member was shown to be related to a person who left DNA on a burlap sack containing one of the buried victims.

There’s nothing groundbreaking here; it’s casting a wide net with cell phone geolocation data and then winnowing it down using other evidence and investigative techniques. And right now, those are expensive and time consuming, so only used in major crimes like murder (or, in this case, murders).

What’s interesting to think about is what happens when this kind of thing becomes cheap and easy: when it can all be done through easily accessible databases, or even when an AI can do the sorting and make the inferences automatically. Cheaper digital forensics means more digital forensics, and we’ll start seeing this kind of thing for even routine crimes. That’s going to change things.

Buying Campaign Contributions as a Hack

The first Republican primary debate has a popularity threshold to determine who gets to appear: 40,000 individual contributors. Now there are a lot of conventional ways a candidate can get that many contributors. Doug Burgum came up with a novel idea: buy them:

A long-shot contender at the bottom of recent polls, Mr. Burgum is offering $20 gift cards to the first 50,000 people who donate at least $1 to his campaign. And one lucky donor, as his campaign advertised on Facebook, will have the chance to win a Yeti Tundra 45 cooler that typically costs more than $300—just for donating at least $1.

It’s actually a pretty good idea. He could have spent the money on direct mail, or personalized social media ads, or television ads. Instead, he buys gift cards at maybe two-thirds of face value (sellers calculate the advertising value, the additional revenue that comes from using them to buy something more expensive, and breakage when they’re not redeemed at all), and resells them. Plus, many contributors probably give him more than $1, and he got a lot of publicity over this.

Probably the cheapest way to get the contributors he needs. A clever hack.

EDITED TO ADD (7/16): These might be “straw donors” and illegal:

The campaign’s donations-for-cash strategy could raise potential legal concerns, said Paul Ryan, a campaign finance lawyer. Voters who make donations in exchange for gift cards, he said, might be considered straw donors because part or all of their donations are being reimbursed by the campaign.

“Federal law says ‘no person shall make a contribution in the name of another person,'” Mr. Ryan said. “Here, the candidate is making a contribution to himself in the name of all these individual donors.”

Richard L. Hasen, a law professor at the University of California, Los Angeles, who specializes in election law, said that typically, campaigns ask the Federal Election Commission when engaging in new forms of donations.

The Burgum campaign’s maneuver, he said, “certainly seems novel” and “raises concerns about whether it violates the prohibition on straw donations.”

Something for the courts to figure out, if this matter ever gets that far.

French Police Will Be Able to Spy on People through Their Cell Phones

The French police are getting new surveillance powers:

French police should be able to spy on suspects by remotely activating the camera, microphone and GPS of their phones and other devices, lawmakers agreed late on Wednesday, July 5.

[…]

Covering laptops, cars and other connected objects as well as phones, the measure would allow the geolocation of suspects in crimes punishable by at least five years’ jail. Devices could also be remotely activated to record sound and images of people suspected of terror offenses, as well as delinquency and organized crime.

[…]

During a debate on Wednesday, MPs in President Emmanuel Macron’s camp inserted an amendment limiting the use of remote spying to “when justified by the nature and seriousness of the crime” and “for a strictly proportional duration.” Any use of the provision must be approved by a judge, while the total duration of the surveillance cannot exceed six months. And sensitive professions including doctors, journalists, lawyers, judges and MPs would not be legitimate targets.

Google Is Using Its Vast Data Stores to Train AI

No surprise, but Google just changed its privacy policy to reflect broader uses of all the surveillance data it has captured over the years:

Research and development: Google uses information to improve our services and to develop new products, features and technologies that benefit our users and the public. For example, we use publicly available information to help train Google’s AI models and build products and features like Google Translate, Bard, and Cloud AI capabilities.

(I quote the privacy policy as of today. The Mastodon link quotes the privacy policy from ten days ago. So things are changing fast.)

Privacy of Printing Services

The Washington Post has an article about popular printing services, and whether or not they read your documents and mine the data when you use them for printing:

Ideally, printing services should avoid storing the content of your files, or at least delete daily. Print services should also communicate clearly upfront what information they’re collecting and why. Some services, like the New York Public Library and PrintWithMe, do both.

Others dodged our questions about what data they collect, how long they store it and whom they share it with. Some—including Canon, FedEx and Staples—declined to answer basic questions about their privacy practices.

Wisconsin Governor Hacks the Veto Process

In my latest book, A Hacker’s Mind, I wrote about hacks as loophole exploiting. This is a great example: The Wisconsin governor used his line-item veto powers—supposedly unique in their specificity—to change a one-year funding increase into a 400-year funding increase.

He took this wording:

Section 402. 121.905 (3) (c) 9. of the statues is created to read: 121.903 (3) (c) 9. For the limit for the 2023-24 school year and the 2024-25 school year, add $325 to the result under par. (b).

And he deleted these words, numbers, and punctuation marks:

Section 402. 121.905 (3) (c) 9. of the statues is created to read: 121.903 (3) (c) 9. For the limit for the 2023-24 school year and the 2024–25 school year, add $325 to the result under par. (b).

Seems to be legal:

Rick Champagne, director and general counsel of the nonpartisan Legislative Reference Bureau, said Evers’ 400-year veto is lawful in terms of its form because the governor vetoed words and digits.

“Both are allowable under the constitution and court decisions on partial veto. The hyphen seems to be new, but the courts have allowed partial veto of punctuation,” Champagne said.

Definitely a hack. This is not what anyone thinks about when they imagine using a line-item veto.

And it’s not the first time. I don’t know the details, but this was certainly the same sort of character-by-character editing:

Mr Evers’ Republican predecessor once deploying it to extend a state programme’s deadline by one thousand years.

A couple of other things:

One, this isn’t really a 400-year change. Yes, that’s what the law says. But it can be repealed. And who knows that a dollar will be worth—or if they will even be used—that many decades from now.

And two, from now all Wisconsin lawmakers will have to be on the alert for this sort of thing. All contentious bills will be examined for the possibility of this sort of delete-only rewriting. This sentence could have been reworded, for example:

For the 2023-2025 school years, add $325 to the result under par. (b).

The problem is, of course, that legalese developed over the centuries to be extra wordy in order to limit disputes. If lawmakers need to state things in the minimal viable language, that will increase court battles later. And that’s not even enough. Bills can be thousands of words long. If any arbitrary characters can be glued together by deleting enough other characters, bills can say anything the governor wants.

The real solution is to return the line-item veto to what we all think it is: the ability to remove individual whole provisions from a law before signing it.

Friday Squid Blogging: Giant Squid Nebula

Pretty:

A mysterious squid-like cosmic cloud, this nebula is very faint, but also very large in planet Earth’s sky. In the image, composed with 30 hours of narrowband image data, it spans nearly three full moons toward the royal constellation Cepheus. Discovered in 2011 by French astro-imager Nicolas Outters, the Squid Nebula’s bipolar shape is distinguished here by the telltale blue-green emission from doubly ionized oxygen atoms. Though apparently surrounded by the reddish hydrogen emission region Sh2-129, the true distance and nature of the Squid Nebula have been difficult to determine. Still, a more recent investigation suggests Ou4 really does lie within Sh2-129 some 2,300 light-years away. Consistent with that scenario, the cosmic squid would represent a spectacular outflow of material driven by a triple system of hot, massive stars, cataloged as HR8119, seen near the center of the nebula. If so, this truly giant squid nebula would physically be over 50 light-years across.

As usual, you can also use this squid post to talk about the security stories in the news that I haven’t covered.

The AI Dividend

For four decades, Alaskans have opened their mailboxes to find checks waiting for them, their cut of the black gold beneath their feet. This is Alaska’s Permanent Fund, funded by the state’s oil revenues and paid to every Alaskan each year. We’re now in a different sort of resource rush, with companies peddling bits instead of oil: generative AI.

Everyone is talking about these new AI technologies—like ChatGPT—and AI companies are touting their awesome power. But they aren’t talking about how that power comes from all of us. Without all of our writings and photos that AI companies are using to train their models, they would have nothing to sell. Big Tech companies are currently taking the work of the American people, without our knowledge and consent, without licensing it, and are pocketing the proceeds.

You are owed profits for your data that powers today’s AI, and we have a way to make that happen. We call it the AI Dividend.

Our proposal is simple, and harkens back to the Alaskan plan. When Big Tech companies produce output from generative AI that was trained on public data, they would pay a tiny licensing fee, by the word or pixel or relevant unit of data. Those fees would go into the AI Dividend fund. Every few months, the Commerce Department would send out the entirety of the fund, split equally, to every resident nationwide. That’s it.

There’s no reason to complicate it further. Generative AI needs a wide variety of data, which means all of us are valuable—not just those of us who write professionally, or prolifically, or well. Figuring out who contributed to which words the AIs output would be both challenging and invasive, given that even the companies themselves don’t quite know how their models work. Paying the dividend to people in proportion to the words or images they create would just incentivize them to create endless drivel, or worse, use AI to create that drivel. The bottom line for Big Tech is that if their AI model was created using public data, they have to pay into the fund. If you’re an American, you get paid from the fund.

Under this plan, hobbyists and American small businesses would be exempt from fees. Only Big Tech companies—those with substantial revenue—would be required to pay into the fund. And they would pay at the point of generative AI output, such as from ChatGPT, Bing, Bard, or their embedded use in third-party services via Application Programming Interfaces.

Our proposal also includes a compulsory licensing plan. By agreeing to pay into this fund, AI companies will receive a license that allows them to use public data when training their AI. This won’t supersede normal copyright law, of course. If a model starts producing copyright material beyond fair use, that’s a separate issue.

Using today’s numbers, here’s what it would look like. The licensing fee could be small, starting at $0.001 per word generated by AI. A similar type of fee would be applied to other categories of generative AI outputs, such as images. That’s not a lot, but it adds up. Since most of Big Tech has started integrating generative AI into products, these fees would mean an annual dividend payment of a couple hundred dollars per person.

The idea of paying you for your data isn’t new, and some companies have tried to do it themselves for users who opted in. And the idea of the public being repaid for use of their resources goes back to well before Alaska’s oil fund. But generative AI is different: It uses data from all of us whether we like it or not, it’s ubiquitous, and it’s potentially immensely valuable. It would cost Big Tech companies a fortune to create a synthetic equivalent to our data from scratch, and synthetic data would almost certainly result in worse output. They can’t create good AI without us.

Our plan would apply to generative AI used in the US. It also only issues a dividend to Americans. Other countries can create their own versions, applying a similar fee to AI used within their borders. Just like an American company collects VAT for services sold in Europe, but not here, each country can independently manage their AI policy.

Don’t get us wrong; this isn’t an attempt to strangle this nascent technology. Generative AI has interesting, valuable, and possibly transformative uses, and this policy is aligned with that future. Even with the fees of the AI Dividend, generative AI will be cheap and will only get cheaper as technology improves. There are also risks—both every day and esoteric—posed by AI, and the government may need to develop policies to remedy any harms that arise.

Our plan can’t make sure there are no downsides to the development of AI, but it would ensure that all Americans will share in the upsides—particularly since this new technology isn’t possible without our contribution.
