![]() ![]() It may not be perfect at the start, but as Google gets more and more photographs to scan, it could become the most accurate auto-tagging service on the Internet. For the rest, I suspect Google is inventing its own supplemental metadata, using rapid image scans and automatic face detection as part of the company's continuous "machine learning" system. It does this in part by scanning your image's metadata: the location and other information your camera builds into the underlying code of your digital image. According to this year's Google I/O keynote, the Photos service will offer a search function that can find people, places, and objects - all without any active tagging on the end user's part. The potential of photographic dataĪn image may be worth 1000 words, but image metadata may spill far more information than that, especially when applied to a Google service. But many others sign up for these services without ever quite realizing what they've given away. For some people, this is a perfectly reasonable tradeoff for "free". ![]() The company uses this data to sell to advertisers, and advertisers in turn get a much closer look at you, your spending habits, and your daily activities. ![]() In plain English, that means being able to sell custom ads against your data: showing you a Nordstrom ad for shoes, for instance, because Google knows from search or web history that you looked at some yesterday, or from Gmail that you purchased heels at the store last week. ![]() The millions of people who sign up for free Google services agree to terms and conditions that give the company permission to access certain subsets of any information you put online. But because the company isn't charging for its services to get those user numbers, it still has to make money - it isn't a charity.Īnd therein comes the potential dark side of Google's data usage, where the company pays its debts by leveraging its biggest asset: you. Google in large part uses this data to improve and expand its services: It needs those vast user numbers to make its services the best in the world. When you offer a free service, you're likely to get many more people to sign up or download it than if that service was offered at a cost. ![]()
