neoprint.attestDevice()

Single trust score combining all detection modules.

Signature

function attestDevice(fp: Fingerprint, options?: {
  strictness?: 'low' | 'medium' | 'high'
  challenge?: string
}): Promise<AttestResult>

Options

• strictness - How many checks to run. Default: 'medium'
• challenge - Server-provided nonce to prevent replay attacks

Returns

interface AttestResult {
  score: number          // 0-1
  isHuman: boolean
  isPhysical: boolean
  isAuthentic: boolean
  factors: string[]      // passed checks
  risks: string[]        // failed checks
  integrityToken: string // signed token for server verification
}

Example

const fp = await neoprint.get()
const proof = await neoprint.attestDevice(fp, {
  strictness: 'high',
  challenge: 'nonce-from-server',
})

if (proof.score >= 0.8 && proof.isAuthentic) {
  // Trusted
}
