How does Safari's Intelligent Tracking Prevention (ITP) defend against browser fingerprinting?

Safari deliberately standardizes system configuration — generic user agent, rounded screen resolution, default fonts, and random "noise" added to canvas data — so devices look alike and are harder to single out.

The four standardizations:

1. User Agent — reports generic versions
2. Screen resolution — rounded to standard values
3. Fonts — limited to system defaults
4. Canvas data — perturbed with random noise

The strategy is anonymity through uniformity: if every Safari device reports the same generic configuration, the fingerprint's entropy collapses and you blend into the crowd. The added canvas noise specifically defeats canvas fingerprinting by making the hash inconsistent.

This is the opposite philosophy to "block the tracker" — instead of stopping the script, Safari makes the signal it collects useless.
