Abstract
Various embodiments are directed to providing a multi-tiered anti-abuse approach to registration of a mobile device user. A registration service may determine whether communications with the mobile device is through a trusted carrier gateway, and if so, then a mobile device identifier may be used to automatically register the mobile device. Otherwise, a determination may be made whether the mobile device is configured to support a challenge-response image. In one embodiment, such determination may be based, in part, on information received from the mobile device through a user agent, or the like. If the mobile device is capable of supporting a challenge-response image, one may be sent to the mobile device to enable registration. If, however, the mobile device does not support the challenge-response image and the carrier gateway is not trusted, the mobile device may be directed to employ an SMS mechanism to complete registration.
