摘要

A verification method and system are disclosed that verify a user. The user is provided a verification code via, for example, a website, to be communicated to the system via an application on a mobile communication device. If the correct verification code is communicated by the user, the user receives via the application a verification message containing another verification code, which the user submits to a website or on-line form or to another verification system for authentication.
