neoprint.detectNoise()

Detect canvas and audio noise injection (Brave farbling, Safari ITP, anti-fingerprint extensions).

Signature

function detectNoise(): Promise<NoiseReport[]>

Returns

interface NoiseReport {
  collector: string   // 'canvas' | 'audio'
  isNoisy: boolean    // true if noise detected
  variance: number    // 0–1
  samples: number     // number of test iterations
}

Example

const reports = await neoprint.detectNoise()

for (const r of reports) {
  if (r.isNoisy) {
    console.log(`${r.collector}: noise detected (variance: ${r.variance})`)
  }
}

How It Works

Renders the same canvas / runs the same AudioContext multiple times. If results differ between runs, noise injection is present.
