Hot on Your Trail: Privacy, Your Data, and Who Has Access to It

Overview

The video uses Liz’s planned trip to Hawaii to illustrate how extensively personal data can be collected and shared. Google and her internet provider can connect her searches and online activity to identifying information. Travel sites, advertising firms, and social-media platforms can track her interests through cookies and embedded buttons, sometimes even when she does not interact with them directly.

Online and Offline Tracking

Tracking extends offline, too. Navigation services and mobile carriers can record Liz’s movements. Data brokers may sell location and purchase information, while shopping centers and stores may monitor her phone, use facial-recognition cameras, or share purchase details. A pharmacy rewards program could also expose sensitive purchases, such as a pregnancy test.

Combining and Accessing Data

The video argues that data from different sources can be combined to create a detailed picture of someone’s life, even when individual companies claim they cannot identify that person.

Law enforcement, private investigators, and attorneys may obtain records such as call logs, location data, internet addresses, and browsing history through a subpoena or court order. The video describes these legal processes as requiring a lower standard of proof than a search warrant.

The central warning is that people have little control over who can access the resulting profile.
