In this episode of Impractical Privacy, Sudo peels back the high-gloss exterior of the postal system to reveal the "Paper Trail" of analog metadata. The show breaks down how every envelope you receive is digitized, indexed, and tracked by a surveillance apparatus that has been running since 2001.
Ultimately, Sudo argues that your home address is the "Primary Key" tying your anonymous online persona to your physical front door and provides technical "physical defense" strategies to decouple your residence from the data brokers' reach.
