Identifying artifacts are inserting in radio frequency broadcast data at
the transmitter and retrieved at a receiver, allowing verification of the
receipt of the transmitted data, authentication of transactions that use
the transmitted data, or activation of processes dependent on receipt of
the carrier data. A content system receives content data to serve as
carrier data, and an identifying artifact insertion system inserts
artifact data into the carrier data based on predetermined
characteristics of the carrier data without requiring human intervention,
and then generates a composite data sequence. A data transmit system
connected to the identifying artifact insertion system and the content
system transmits the composite data sequence. A receiver system performs
real-time, automated extraction of identifying artifacts within lossy
carrier data and verifies the reception of the data artifacts in the
carrier data.
