Abstract
A cyber mall system has a contents sales apparatus for selling digital contents, a contents purchasing apparatus, and a network for connecting these components. When digital contents are registered into the contents sales apparatus, digital contents personal using conditions are generated on the basis of digital contents using conditions and are provided to a customer. If the digital contents are again purchased after the delivery of the digital contents fails, as long as the digital contents personal using conditions provided at the time of purchase are valid, the digital contents are again delivered without again collecting a digital contents value.
