DATA TRANSFERRING METHOD

摘要

A data transmission method is provided to transmit data requested from a client to their destination efficiently by using a multi-chain under a DRM(Digital Rights Management) interoperable environment. A method for transmitting data under a data interoperable environment comprises the steps of: receiving a data transmission request message from a client which requests the transmission of data to at least one destination(S121); collecting the information as to the units which will be involved in the data transmission(S122); forming plural chains, which include at least two units, based on the collected information and transmitting the data to at least one destination through the plural chains(S127-S129).
