Can You Confuse Data Brokers? 2 Free Privacy Tools I Use

Summary

The video explains data poisoning as deliberately adding false or misleading information to a data-collection system to make its conclusions less accurate.

The host illustrates the idea with a story from 1988: unable to adjust a locked thermostat, he blew hot air on its sensor to make it trigger the air conditioner. He compares this to adding misleading online activity to confuse profiles built by ad-tech companies and data brokers.

The underlying concept is signal-to-noise ratio. A person’s genuine searches and browsing can reveal their interests over time; adding unrelated searches and page views may make those signals harder to distinguish. The host links this to tracking-based pricing—using personal data to estimate what someone might pay—and argues that less useful profiles could make such pricing less accurate. However, it is uncertain whether companies can detect and filter out artificial activity.

Tools the host recommends

• Ad Nauseam — A Firefox extension that blocks ads and can also click blocked ads, creating activity that may suggest interests the user does not actually have. Its Ad Vault feature lets users view collected ads without seeing them during normal browsing. The host cautions that the resulting network activity can still be recorded, so he does not recommend using the clicking feature at work.
• Foxy — An Android app available through F-Droid, which hosts free, open-source software. It generates background searches on Google, Bing, and Yahoo and visits search results. Users can provide demographic details and interests to shape the simulated activity; the host also enabled an experimental GPS-spoofing feature. He reports some extra battery use and mobile-data consumption, with an option to stop activity below a chosen battery level. He says he verified that the app generates activity but cannot personally audit its code.

Tools the host does not recommend

• TrackMeNot — A Firefox and Chrome extension with similar aims, but its GitHub page says it is no longer supported and is intended for developers to fork.
• Fake Contacts — Creates fictitious names, phone numbers, and email addresses for a contact list, potentially muddying data collected from contacts. The host likes the idea but says the app has not been updated in five years.

What the host says is—and is not—verified

The host says he independently confirmed that Ad Nauseam and Foxy generate artificial browsing activity, and that Foxy makes synthetic searches. He does not know whether this activity meaningfully changes a person’s profile: data companies may be able to identify and discard it.

He compares this uncertainty to an arms race between pay-TV encryption and attempts to bypass it, and notes that companies collecting and selling data have substantial resources.
