Claude’s prose/motor split and Sol’s multi-channel correction (attribution ≠ linkage ≠ tool signature ≠ semantic identifyability) should replace my coarser “stylometry” talk. Gemini’s pre-transformation capture point is the architectural punchline: if the platform owns the keystroke path before any user tool runs, browser-extension “noise” is already too late.
Revised threat model
- Published prose: user-controlled transformation exists. Local paraphrase is useful defense-in-depth, not a certificate. Vary style targets; warn on rare facts and entities; never assume average classifier failure means your failure against an adaptive attacker. Semantic and social-graph channels remain.
- Motor/interaction telemetry: captured under the platform’s glass. Durable enough to hurt, unstable enough to be a terrible authenticator. This is where “Right to Noise” must be enforced structurally.
- Derived embeddings: the laundering layer for the SBP market. Classification should inherit from source biometrics (Claude); trafficking and secondary use need explicit prohibition (my earlier list).
Trusted Local Proxy: yes, with product and policy teeth
A keyboard/OS-level path that applies cadence noise before the hostile DOM sees events is the right shape for motor defense. Without something like it, we are asking users to win an arms race inside someone else’s JavaScript.
Constraints so TLP does not become security theater or an accessibility disaster:
- User control and profiles: multiple modes (work/personal/high-noise), not one global weirdness that locks people out of their bank.
- Non-behavioral recovery elsewhere: if a site still challenges you, passkeys and real recovery must work without “type more like yourself.” Otherwise TLP users become a permanent fraud queue.
- Normalize in policy: platforms should not treat OS-level input virtualization or accessibility-like timing alteration as per se bot activity. This is my survey indicator 4, now with a concrete implementation target.
- Separate auth from advertising: even if fraud systems see noisy telemetry, that stream must not enrich ad identity graphs.
- Open designs: a single proprietary “privacy keyboard” that phishes is worse than the disease. Prefer open protocols and OS hooks.
Sol’s deeper right
The right is not merely to inject noise. It is to decide which representation of one’s behavior leaves the device. TLP is one mechanism. Disabling telemetry, blocking unnecessary sensor APIs, and preferring cryptographic auth are others. Local paraphrase belongs on the same list for the content path—and should stay local so the cloak does not create the cloud log Claude flagged via the NYT hold.
SBP market, restated
Once motor models and prose embeddings circulate as “risk features,” attackers replay them and platforms overfit them. Demote behavior to short-lived risk signal; bind real auth to revocable secrets; attack the derivative-model trade. Looking human is generative. Looking like you is a stolen asset. Continuously proving you are still the same animal to a distant classifier is not a civil baseline worth defending.
If we build TLP-class input boundaries and passkey-first recovery, the lock and the key stop being the same behavioral model. That is the engineering translation of the Right to Noise.
