What prevents someone from creating multiple PlaySafe ID's?
Your PlaySafe ID is tied to your verified identity. Not your email address, game account, or any other credential that can simply be recreated. When you first verify, a hashed biometric token is generated from your identity document and selfie. This hash is unique to you, irreversible and is retained specifically to ensure that the same person can never successfully complete verification a second time.
If someone attempts to create a new PlaySafe ID, they would need to pass the same identity verification process again. Hashing works by taking a set of inputs and producing a fixed, unique output. Critically, the same inputs will always produce the same output, as well as being irreversible and containing no readable or direct source data. It is simply a unique string of characters with no way to trace it back to the original information.
This means that when the same person attempts to verify again, the same hash is produced, our system recognises it as already existing, and the new account is blocked from being created. There is no way around this without a different identity.
This is the same zero-knowledge process developed with our verification partner Entrust that ensures no documents or biometric data are stored, while still guaranteeing that each person can only ever hold one PlaySafe ID.
