Wij willen met u aan tafel zitten en in een openhartig gesprek uitvinden welke uitdagingen en vragen er bij u spelen om zo, gezamelijk, tot een beste oplossing te komen. Oftewel, hoe kan de techniek u ondersteunen in plaats van dat u de techniek moet ondersteunen.

After a Wall Street Journal investigation concluded that there are millions of fake business listings on Google Maps, the company has issued a response detailing the measures it takes to combat the problem.

According to estimates from online advertising experts surveyed by the WSJ, there are “roughly 11 million falsely listed businesses on any given day,” with hundreds of thousands more fake listings appearing every month. Many are placed by businesses that specialized creating fake listings for clients that want to boost their information above competitors in search results.

According to a search expert interviewed by the WSJ, a 2017 academic study paid for by Google that found only 0.5% of local searches researchers examined were fake was skewed by limited data.

In the company’s response, Google Maps product director Ethan Russell wrote that of the more than 200 million listings added to Google Maps over the years, only a “small percentage” are fake. He said that last year Google took down more than 3 million fake business profiles, including more than 90% that were removed before users could see them. Google’s systems identified 85% of the listings removed, while 250,000 were reported by users. The company also disabled 150,000 user accounts found to be abusive, a 50% increase from 2017.

Russell wrote that the company is “continually working on new and better ways to fight these scams using a variety of ever-evolving manual and automated systems,” but can’t share more details about them because otherwise scammers might find a way to get around them.

The WSJ report comes as another Google-owned service, YouTube, is under scrutiny for how it fights abuse at scale. YouTube released its first anti-abuse report last year, but problematic content, including hate speech, continues to be a major problem and the platform’s critics say it haphazardly enforces its own policies.

Along with Apple, Amazon and Facebook, Google’s parent company Alphabet is currently facing antitrust investigations by the Federal Trade Commission and Justice Department, and its search business is expected to go under scrutiny.

There’s a whole lot of ocean on this planet, and we don’t have much of an idea what’s at the bottom of most of it. That could change with the craft and techniques created during the Ocean Discovery Xprize, which had teams competing to map the sea floor quickly, precisely and autonomously. The winner just took home $ 4 million.

A map of the ocean would be valuable in and of itself, of course, but any technology used to do so could be applied in many other ways, and who knows what potential biological or medical discoveries hide in some nook or cranny a few thousand fathoms below the surface?

The prize, sponsored by Shell, started back in 2015. The goal was, ultimately, to create a system that could map hundreds of square kilometers of the sea floor at a five-meter resolution in less than a day — oh, and everything has to fit in a shipping container. For reference, existing methods do nothing like this, and are tremendously costly.

But as is usually the case with this type of competition, the difficulty did not discourage the competitors — it only spurred them on. Since 2015, then, the teams have been working on their systems and traveling all over the world to test them.

Originally the teams were to test in Puerto Rico, but after the devastating hurricane season of 2017, the whole operation was moved to the Greek coast. Ultimately after the finalists were selected, they deployed their craft in the waters off Kalamata and told them to get mapping.

Team GEBCO’s surface vehicle

“It was a very arduous and audacious challenge,” said Jyotika Virmani, who led the program. “The test itself was 24 hours, so they had to stay up, then immediately following that was 48 hours of data processing after which they had to give us the data. It takes more trad companies about 2 weeks or so to process data for a map once they have the raw data — we’re pushing for real time.”

This wasn’t a test in a lab bath or pool. This was the ocean, and the ocean is a dangerous place. But amazingly there were no disasters.

“Nothing was damaged, nothing imploded,” she said. “We ran into weather issues, of course. And we did lose one piece of technology that was subsequently found by a Greek fisherman a few days later… but that’s another story.”

At the start of the competition, Virmani said, there was feedback from the entrants that the autonomous piece of the task was simply not going to be possible. But the last few years have proven it to be so, given that the winning team not only met but exceeded the requirements of the task.

“The winning team mapped more than 250 square kilometers in 24 hours, at the minimum of five meters resolution, but around 140 was more than five meters,” Virmani told me. “It was all unmanned: An unmanned surface vehicle that took the submersible out, then recovered it at sea, unmanned again, and brought it back to port. They had such great control over it — they were able to change its path and its programming throughout that 24 hours as they needed to.” (It should be noted that unmanned does not necessarily mean totally hands-off — the teams were permitted a certain amount of agency in adjusting or fixing the craft’s software or route.)

A five-meter resolution, if you can’t quite picture it, would produce a map of a city that showed buildings and streets clearly, but is too coarse to catch, say, cars or street signs. When you’re trying to map two-thirds of the globe, though, this resolution is more than enough — and infinitely better than the nothing we currently have. (Unsurprisingly, it’s also certainly enough for an oil company like Shell to prospect new deep-sea resources.)

The winning team was GEBCO, composed of veteran hydrographers — ocean mapping experts, you know. In addition to the highly successful unmanned craft (Sea-Kit, already cruising the English Channel for other purposes), the team did a lot of work on the data-processing side, creating a cloud-based solution that helped them turn the maps around quickly. (That may also prove to be a marketable service in the future.) They were awarded $ 4 million, in addition to their cash for being selected as a finalist.

The runner up was Kuroshio, which had great resolution but was unable to map the full 250 km2 due to weather problems. They snagged a million.

A bonus prize for having the submersible track a chemical signal to its source didn’t exactly have a winner, but the teams’ entries were so impressive that the judges decided to split the million between the Tampa Deep Sea Xplorers and Ocean Quest, which amazingly enough is made up mostly of middle-schoolers. The latter gets $ 800,000, which should help pay for a few new tools in the shop there.

Lastly, a $ 200,000 innovation prize was given to Team Tao out of the U.K., which had a very different style to its submersible that impressed the judges. While most of the competitors opted for a craft that went “lawnmower-style” above the sea floor at a given depth, Tao’s craft dropped down like a plumb bob, pinging the depths as it went down and back up before moving to a new spot. This provides a lot of other opportunities for important oceanographic testing, Virmani noted.

Having concluded the prize, the organization has just a couple more tricks up its sleeve. GEBCO, which stands for General Bathymetric Chart of the Oceans, is partnering with The Nippon Foundation on Seabed 2030, an effort to map the entire sea floor over the next decade and provide that data to the world for free.

And the program is also — why not? — releasing an anthology of short sci-fi stories inspired by the idea of mapping the ocean. “A lot of our current technology is from the science fiction of the past,” said Virmani. “So we told the authors, imagine we now have a high-resolution map of the sea floor, what are the next steps in ocean tech and where do we go?” The resulting 19 stories, written from all 7 continents (yes, one from Antarctica), will be available June 7.

Social sharing site and news aggregator Flipboard has reset millions of user passwords after hackers gained access to its systems several times over a nine-month period

The company confirmed in a notice Tuesday that the hacks took place between June 2, 2018 and March 23, 2019 and a second time on April 21-22, 2019, but the intrusions were only detected a day later on April 23.

Hackers stole usernames, email addresses, passwords and account tokens for third-party services. According to the notice, “not all” Flipboard users’ account data were involved in the breaches but the company declined to say how many users were affected.

Flipboard has about 150 million monthly users.

“We’re still identifying the accounts involved and as a precaution, we reset all users’ passwords and replaced or deleted all digital tokens,” the notice read.

Although the passwords were unreadable, Flipboard said passwords prior to March 14, 2012 were scrambled using the older, weak hashing SHA-1 algorithm.. Any passwords changed after are scrambled using a much stronger algorithm that makes it far more difficult to reveal in a usable format.

The hacks also exposed account tokens, which gives Flipboard access to data from accounts on other services, like Facebook, Google, and Samsung.

“We have not found any evidence the unauthorized person accessed third-party account(s) connected to users’ Flipboard accounts,” said the statement. “As a precaution, we have replaced or deleted all digital tokens.”

Flipboard becomes the latest tech giant to be hit by hackers in recent months. Developer platform Stack Overflow earlier this month confirmed a breach involved some user data. Canva, one of the biggest sites on the internet, was also hacked. Last week, the Australia-based company admitted close to 140 million users had data stolen following the breach.
