Device Attestation
Security
Cryptographic proof of device integrity/state to a relying party; often hardware-backed and privacy-sensitive.
Definition
Attestation uses signed statements to report device integrity signals. Used for anti-fraud/DRM/security gating. Privacy impact depends on whether stable identifiers are involved and how signals are retained.
In plain English
Cryptographic proof of device integrity/state to a relying party; often hardware-backed and privacy-sensitive.
Why this matters
Why it matters: Can block compromised devices, but can also reduce anonymity and enable fingerprinting.
Example
Example: Use minimal signals, avoid stable identifiers, and document privacy impact in notices and retention rules.
