Abstract: PROBLEM TO BE SOLVED: To provide users with a method for surely receiving data on a system from a web broadcast communication interface through a plurality of channels. SOLUTION: This method includes a step, where promotion meta data that are available for reception are received through a 1st web broadcast communication channel and at least part of the data is assembled into promotion offering data, a step where data to be received are selected in relation to the above data, a step where data are received from a 2nd web broadcast communication channel, a step where the data are selected from the promotion meta data and encrypted by using a 1st encryption key, and a step where a computer- readable medium receives a 1st encryption decoding key, and the decoding key is used to decode at least part of the encrypted data received from the 2nd web broadcast communication channel.
