A whitelist is a list of devices or apps that are allowed only within your crypto-currency exchange’s IT infrastructure. Use this definition for registration and you can regulate which devices are qualified to register in your white label cryptocurrency exchange software.
For example, you can build a whitelist of accepted iOS devices in a deployment of the traders ‘ devices. You can use International Mobile Equipment Identity (IMEI), Serial Number, or Unique Device Identifier (UDID) to base that list of devices. In this way, enrollment is limited to only those devices that you have defined, and any other devices that preclude enrollment.
Upon enrollment in your cryptocurrency exchange, a user’s registration record is updated with the device information. When the device is unenrolled, any other user who tries to enroll the same device will be blocked from enrolling until the previous user’s registration record is removed.
