ABSTRACT:
A data communications system which communicates data via a data communications network, includes: an information extraction unit configured to extract an extraction target from received data; an comparison information generator/transmitter unit configured to generate and transmit comparison information including the extraction target extracted by the information extraction unit; a comparison unit configured to compare the received comparison information with the received data; and a cancellation processor unit configured to delete the received data, when the received comparison information agrees with the received data.
