It's official: Your browsing history can be sold to advertisers. President Trump on Monday signed a measure reversing rules that would have required internet providers to get consent before selling your browsing history.

The rules had not yet gone into effect, but providers now find themselves with new freedom when it comes to collecting and selling their customers' data. What does that mean for you?

What identifying information do they have?

Internet providers already collect a lot of information that's necessary to maintain their networks, like your location and what you're looking at online.

Many have said they will not use "sensitive" information, like medical records, children's data and banking details without consent. However a simple browsing history can reveal those personal details, such as symptoms you've Googled. There are concerns that it would be possible to identify people based on this detailed information.

According to Dane Jasper, cofounder of Sonic, an independent ISP located in California, an internet provider can infer a lot about you based just on your browsing. In addition to basics like age and gender, they might know who your friends are, if you're a recovering alcoholic, or where you went to school. In theory, they could create an in-depth profile of you.
