One embodiment of a method of authenticating data comprises the steps of: receiving, at the device, data in a plurality of packets transmitted by a data server; submitting a request for a server-computed authentication value to a data authentication server, wherein the data authentication server is adapted to compute the server-computed authentication value based on a subset of the data transmitted by the data server; receiving, at the device, the server-computed authentication value from the data authentication server in response to the request; computing a device-computed authentication value based on a subset of the data received at the device corresponding to the subset of the data transmitted by the data server; and determining if the subset of the data received at the device is authentic by comparing the server-computed and device-computed authentication values.
FIELD OF THE INVENTION Embodiments of the invention relate generally to the transmission of data to devices, such as mobile devices for example, and more specifically to a system and method for authenticating data transmitted to such devices.
BACKGROUND OF THE INVENTION Mobile devices typically provide a number of different modes of communication. For example, a mobile device may be used to send and receive both voice and data communications. More specifically, with regards to data communications, a mobile device may allow different types of messages to be sent and received, including electronic mail messages, text messages, and personal identification number (PIN) messages, for example. Furthermore, many mobile devices are also adapted to receive multimedia content, which may include audio, video, web pages, and other information, some of which may be obtained from the Internet.
DETAILED DESCRIPTION Embodiments of the systems and methods described herein are generally directed to a technique for facilitating the authentication of streamed data received at a device in which authentication information is not distributed over the data stream. In at least one embodiment, information required to authenticate a particular subset of the data already received at a device is requested from a server.
