Abstract
A data-publishing system facilitates broadcasting a data stream so that each client device obtains a personalized data stream. During operation, a publisher can generate an encoded data stream that does not include a reproducible version of the data stream's contents, and generates an encoding sauce to provide to at least one data-brokering system. When a broker receives a request from a client device for access to the data stream, the broker validates the client device's access to the data stream, and uses the encoding sauce to generate a secret sauce for the client device. The client device can process the encoded data stream using instructions in the secret sauce to produce a personalized data stream that includes a reproducible version of the data stream's contents.
