1. Visitor identifiers, in comparison to fingerprints, include server-side techniques, are deduplicated and utilize fuzzy matching to result in a more accurate and stable identifier. Fingerprint hashes rely on an exact match across all browser attributes, making them less stable across > 4-week time intervals.

2. Fingerprint is GDPR and CCPA compliant, ISO 27001 certified, and SOC 2 Type II compliant. You still need to be compliant as the data controller and use the identification for fraud prevention under legitimate interest or ask for consent.
