iOS IDAnchor is a Customer Identity Protection (CIP) solution that delivers a persistent, tamper-proof Mobile Device ID for iOS apps by binding each session to a trusted iOS environment. It uses immutable signals from the iOS device, app install, app release, and DevOps workspace to generate a stable identity that survives app reinstalls, device resets, and OS upgrades. This prevents identity spoofing, IDFA manipulation, device cloning, and other forms of mobile fraud that evade detection using legitimate logins. iOS IDAnchor helps enforce contextual risk checks and compliance requirements such as PSD2 and FFIEC—without depending on personal data.
