Basic Usage

from cursory import generate_trajectory

trajectory: list[tuple[float, float]]
timings: list[int]
trajectory, timings = generate_trajectory(target_start=..., target_end=...)

Methodology

Cursory generates Mouse Trajectories following these steps:

1. Find a close matching human Trajectory: Cursory has a database of thousands of Trajectories recorded from real humans. It finds the closest matching Trajectory to the target Points with some amount of randomization.
2. Morph the Trajectory: The Trajectory is morphed to fit the target Points exactly, while keeping the overall shape as close to the original as possible.
3. Add Noise: The Trajectory is jittered and knotted, to alter positions slightly to avoid fingerprinting by hash-fingerprinting.
4. Regenerating with Timings: The Trajectory is regenerated using the Trajectory Frequency, with some noise added to the timings to avoid.
5. Re-Add Noise: The Trajectory is jittered and knotted, to alter positions slightly to avoid fingerprinting by hash-fingerprinting.
6. Morph the Trajectory: The Trajectory is morphed to fit the target Points exactly, while keeping the overall shape to the original as possible.

[!WARNING]
Theoretically, it is possible to detect/fingerprint Mouse Trajectories generated by Cursory. But this would require an amount of compute power which is unfeasible. A greater risk of detection would be bad Trajectories, which is mitigated by the advanced algorithms used by Cursory.
