Facebook’s Extensive Surveillance Network – Schneier on Security
Facebook’s Extensive Surveillance Network
Consumer Reports is reporting that Facebook has built a massive surveillance network:
Using a panel of 709 volunteers who shared archives of their Facebook data, Consumer Reports found that a total of 186,892 companies sent data about them to the social network. On average, each participant in the study had their data sent to Facebook by 2,230 companies. That number varied significantly, with some panelists’ data listing over 7,000 companies providing their data. The Markup helped Consumer Reports recruit participants for the study. Participants downloaded an archive of the previous three years of their data from their Facebook settings, then provided it to Consumer Reports.
This isn’t data about your use of Facebook. This data about your interactions with other companies, all of which is correlated and analyzed by Facebook. It constantly amazes me that we willingly allow these monopoly companies that kind of surveillance power.
Here’s the Consumer Reports study. It includes policy recommendations:
Many consumers will rightly be concerned about the extent to which their activity is tracked by Facebook and other companies, and may want to take action to counteract consistent surveillance. Based on our analysis of the sample data, consumers need interventions that will:
- Reduce the overall amount of tracking.
- Improve the ability for consumers to take advantage of their right to opt out under state privacy laws.
- Empower social media platform users and researchers to review who and what exactly is being advertised on Facebook.
- Improve the transparency of Facebook’s existing tools.
And then the report gives specifics.
