Abstract: Systems and methods are provided for migration of users to one or more services offered by a service host. An exemplary method includes detecting, by a computing device associated with the service host, a first dispute message associated with a user and transmitted from a dispute service of the service host to a clearing service of the service host, and appending the user to a black list in response to the first dispute message. The method also includes detecting, by the computing device, a second dispute message associated with the user and transmitted to the clearing service, determining whether the user is included in the black list, and rejecting the second dispute message when the user is included in the black list, thereby inhibiting the user from transmitting the second dispute message to the clearing service outside of the dispute service.

Abstract: A method of authenticating a user with a computing device associated with a camera is described. The computing device obtains first data from a token held by the user, and then captures a user image with the camera. The first data and the captured user image are then sent to an authentication server. If a record matches the first data, the record comprising the first data and a stored user image, the computing device receives information to indicate whether the user is authenticated. A suitable computing device is described, together with a suitable authentication server and an associated method carried out at the authentication server.
