How much is your face worth? Google says $ 5

How do you train a facial recognition AI that is said to be sophisticated enough to compete with Apple's Face ID technology? Quite simply, they offer strangers $ 5 when they lend their faces.

At least, Google employees collected facial scans this way. This is from reports from Android Police and ZDNet, which Google has confirmed to Verge today. In various cities around the country, they are reportedly distributing Starbucks and Amazon 5-dollar gift cards to people on the street in exchange for the not-so-creepy request of some selfies. This "field research," as the company called it, was an attempt to gather additional facial scanning data to ultimately improve the accuracy of Pixel 4's upcoming face recognition technology. Google has collected infrared, color, and depth data for every scan, giving us a glimpse into how the technology works.

In particular, a Google spokesman told Verge that the company was trying to increase the variety of faces that Pixel 4 could detect. This is an understandable precaution given the fact that facial recognition technology was developed only on the basis of gender and ethnicity (unless this company is Amazon).

"Our goal is to develop the feature with robust security and performance," a Google spokesman told Verge. "We also build it with an eye to inclusiveness, so that as many people as possible can benefit from it." be for Project Soli. Project Soli is a series of radar-based sensors that the company has been working on for years, detecting and tracking the motion of nearby objects. In this way, users can unlock the phone using the speakerphone and perform certain gestures. In the video we see a young girl flipping through the music with a wave of her hand.

Given Google's claim, its technology is secure enough that you can authenticate payments and log in to apps with just your face in Pixel 4, it No wonder they went out of their way to get it right. And as a hint, the company said these scans did not leave the device, and users' faces were not stored in the cloud or shared with other Google services.

Google informed Verge that it intends to keep the facial scans collected as part of its investigation for 1

8 months, despite the fact that the declarations of consent issued by them provided for a period of 5 years. These scans also received an abstract identity number separate from the specified email address, and were "encrypted and restricted" so they would not be linked to a Google ID that the person might have.

Fighting Apple has reportedly used more than a billion images for the development of its Neural Network Neural Networks. Less scary? Certainly. More effective? I think we'll see when the Pixel 4 release hits the market.
