The Problem
Behavioral telemetry is easily spoofed by modern AI, leading to a cycle of constant re-training.
The Cycle
Bots learn to mimic human patterns, forcing defenders to tighten thresholds, which hurts real users.
The Shift
Moving from subjective behavioral variables to immutable physical constants.
The Solution
TrustSig uses deterministic hardware attestation that cannot be faked or poisoned.
It is the process where bot developers feed AI models with human-like interaction data, such as mouse movements and click speeds, to trick detection systems into classifying the bot as a human.
Behavior is a choice or a pattern that can be simulated. Physical constants, such as clock skew and oscillator drift, are immutable properties of the hardware itself. They cannot be 'learned' or faked by software.
No. TrustSig is privacy-first. We do not track user behavior or store personal data. We verify the environment, not the person.
The Anatomy of the Poisoning Cycle
For years, the industry has relied on behavioral telemetry to distinguish humans from bots. We have measured mouse movements, click speeds, and typing cadence. While this worked in the early days of bot mitigation, we think it has reached a point of diminishing returns.
We call this the Poisoning Cycle. As defenders, we set thresholds for what a "human" looks like. Bot developers then use machine learning to train their scripts to mimic those exact patterns. When the bots successfully pass, we tighten our thresholds. This makes the system more sensitive, which inevitably leads to more false positives for real users. It is a never-ending game of cat and mouse that favors the attacker.
Why Behavioral Telemetry Fails
Behavioral telemetry is fundamentally subjective. It relies on the assumption that a bot will always act like a machine. However, modern headless browsers and automation frameworks are now capable of injecting jitter, randomizing movement curves, and simulating human-like latency.
When you rely on behavior, you are essentially trying to guess the intent of the user. In our opinion, this is a flawed strategy. If a bot can perfectly replicate the movement of a mouse, the behavioral signal becomes noise. The data is poisoned, and the security layer becomes ineffective.
The TrustSig Shift: Physical Constants
At TrustSig, we believe the solution is to stop looking at what the user is doing and start looking at what the user is.
Instead of analyzing how a user moves their mouse, we analyze the physical reality of the device. We look for physical constants:
- Clock skew: The microscopic differences in how a CPU processes time.
- Oscillator drift: The unique frequency variations in hardware components.
- Rendering fingerprints: The specific way a GPU processes WebGL or canvas elements.
These are not patterns that can be learned or simulated. They are immutable properties of the silicon and the rendering pipeline. You cannot train a bot to fake the physical clock skew of a specific processor. It is a deterministic fact of the hardware.
Ending the Cycle
By moving to hardware-level attestation, we remove the need for the Poisoning Cycle entirely. We do not need to constantly update our models to catch the latest bot behavior because the underlying hardware reality does not change.
This approach allows us to provide a frictionless experience. Because we are not asking the user to solve a puzzle or move their mouse in a specific way, the verification happens invisibly in the background. We believe this is the only way to secure the modern web without sacrificing privacy or user experience.
TrustSig provides a deterministic defense that treats every request as a unique hardware event. By focusing on physical constants, we ensure that your security remains robust, regardless of how sophisticated the bot's behavioral mimicry becomes.
