Large capacity data sales mediation server and method

Abstract

An animation data sales mediation method, an animation data sales mediation system and so on are capable of providing large capacity data such as animation data by a large capacity storage medium in advance, rendering the time required for transfer of the data via the network extremely short by passing a key code for viewing the animation data via the network, rendering the labor and costs required for sales of the animation data extremely low, and providing the latest unauthorized copy technology to the animation data. The animation data sales mediation system has the steps of having a user terminal send to a large capacity data sales server an online access code corresponding to the large capacity data one to one, having the large capacity data sales server send the key code to the user terminal, having the user terminal encrypt and store the key code, and having the animation data used by using the key code.

Problems solved by technology

According to the above conventional technology, however, time required for transmitting data is extremely long in the case of distributing or selling large capacity data of a data amount (capacity) far larger than music data, such as animation data, map data and dictionary data is conducted.

For this reason, communication costs and so on also become huge.

In addition, sending and receiving data of such large amount put an enormous load on a communication environment.

Therefore, distribution and sales of data via the network is effective for data of a small capacity such as melody data for incoming tone as in the above conventional technology, but it is not practical in the case of large capacity data such as animation data.

As for a sales and distribution method of the animation data using such storage media, however, various problems are pointed out.

A first problem is that this large capacity data may be distributed to a number of unspecified persons.

A second problem is that this large capacity data becomes expensive.

A third problem is that much labor and costs are required therefor.

The first problem is a problem of so-called unauthorized copies.

For instance, a variety of technologies for preventing unauthorized copies are installed on the DVD-ROM, but these unauthorized copy preventing technologies are uniformly provided as a standard of the DVD-ROM, and so their level relatively become lower and vulnerable as the technology level is ever rising.

The second problem arises because such a sales method only allows assignment of the large capacity data.

To be more specific, it is very expensive to sell and/or distribute storage media in which the large capacity data is stored because recovering the storage media is difficult as compared with the cases of renting them (assignment with a deadline).

The third problem arises because large capacity media must be sold by way of an actual distribution channel.

For instance, a still popular sales method of delivering an animation medium to a predetermined retailer and collecting a price from a purchaser r
