ABSTRACT:
A method of securely receiving data on a user's system from a web broadcast infrastructure with a plurality of channels. The method comprising receiving promotional metadata from a first web broadcast channel, the promotional metadata related to data available for reception; assembling at least part of the promotional metadata into a promotional offering for review by a user; selecting by a user, data to be received related to the promotional metadata; receiving data from a second web broadcast channel, the data selected from the promotional metadata, and wherein the data has been previously encrypted using a first encrypting key; and receiving the first decrypting key via a computer readable medium, the first decrypting key for decrypting at least some of the data received via the second web broadcast channel. In another embodiment, a method and system to transmit data securely from a web broadcast center is disclosed.
