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.

Contents sales method and cyber mall system using such method and storage medium storing therein its contents sales program

In comparison to unnecessary page generation of the prior art, the page generation time according to the current invention is substantially reduced, and the generated page is efficiently accessed. Since in response to at least one of a predetermined set of update events, a page is dynamically generated in advance of a user page request and the dynamically generated page is stored, the current invention allows the efficient page access. The efficient page access is accomplished by storing the dynamically generated page as a static page at a URL identified by a page access call with an argument. Thus, the user accesses the previously generated dynamic page at a high-speed. The use of the prior art technologies such as proxy servers in combination further improves the cost of transmission of the page to the user according to the current invention.

Dynamic web page generation method and system

In a digital content distribution method to distribute digital contents via a network, distribution of a digital content is instructed according to a distribution schedule, the digital content is distributed according to the distribution schedule indicated, and a particular digital content is selected from the digital contents distributed and is then sold, thereby conducting the distribution of digital contents at a high speed.

Method of and a system for distributing digital contents

The present invention relates to a digital contents selling system for selling digital contents. Identification information of digital contents selected by a customer is received. Personal digital contents are generated by setting identification information for identifying the customer in the selected digital contents as status information for permitting the customer to replay the selected digital contents. The generated digital contents are sold. Thereby, a technique is provided for preventing the illegal use of the sold digital contents.

Method and apparatus for selling digital contents, processing program thereof and recording medium for the program

A delivery schedule management method of managing delivery schedule of delivery data in an electronic data in an electronic data in an electronic data distribution system. The system connects a delivery data server for inputting the delivery data, a digitization server for digitizing the delivery data, a storage and management server for storing and managing electronic delivery data, a delivery management sever for managing delivery of the electronic delivery data, and an electronic user terminal for receiving delivered electronic data and treating received electronic data to one another through a network.

Delivery schedule management method, apparatus for implementing the method, processing program thereof and medium having the program recorded therein

In a method of preventing an illegal use of digital contents, a status information for controlling the replay processing of the digital contents is set in the digital contents. The replay processing of the digital contents is controlled in accordance with a value of the status information thus set. Thereby, a technique can be provided which is capable of preventing the illegal use of the digital contents within the various types of shopping centers and retail outlets.

A cyber mall system has a contents sales apparatus for selling digital contents, a contents purchasing apparatus, and a network for connecting those components. When the digital contents are registered into the contents sales apparatus, in the case where the digital contents are sold by the contents sales apparatus for defining digital contents using conditions constructed by a server side access control to the digital contents which is executed on the contents sales apparatus side and a physical act restriction to control an access to the digital contents which is executed on the contents purchasing apparatus side that purchased the digital contents, digital contents personal using conditions are generated on the basis of the digital contents using conditions and are given to a customer. When the digital contents are again purchased if the delivery of the digital contents fails, so long as the digital contents personal using conditions given at the time of purchase are valid, the digital contents are again delivered without again collecting a digital contents value.
