pub struct SampleSet { /* private fields */ }Expand description
Source images a challenge draws its nine tiles from.
An attacker who holds the same images can render every rotation offline and match the upright tile without any model. Measured at 99.5% top-1 accuracy against a known corpus. Treat the corpus as the security boundary: supply your own, keep it large, and rotate it.
A corpus of n images is fully harvested in roughly
n * ln(n) requests, after which its size no longer helps.
Implementations§

impl SampleSet
Sourcepub fn new(format: SampleFormat, images: Vec<Vec<u8>>) -> Result<Self>
pub fn new(format: SampleFormat, images: Vec<Vec<u8>>) -> Result<Self>
§Errors
Returns CaptchaError::InvalidInput
if images is empty, longer than 4096,
or contains an empty entry.

pub fn demo_insecure() -> Self
The eight images published inside this crate.
Anyone can download them from crates.io and precompute the answer to every challenge they produce. Tests, examples and benchmarks only.
