Onion-routing network providing source IP obfuscation.

Definition

Tor uses layered encryption and relay circuits to separate user identity (source) from destination, reducing linkability for network observers.

In plain English Onion-routing network providing source IP obfuscation.

Why this matters

Why it matters: It improves privacy against network-level surveillance, but endpoints and browser fingerprinting can still reduce anonymity.

Example

Example: Tor circuit with guard, middle, and exit relays for outbound web access.
