Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique effective when applied to a distribution system for software such as computer programs or video works, especially digitalized software.

[0002]

2. Description of the Related Art When a large-scale storage medium such as a CD-ROM comes into the market, it is expected that not only computer programs but also images and sounds will be stored as digital information in the medium for sale.

That is, a video work that has been conventionally supplied on a video tape is directly stored in a CD-ROM for sale, or a game utilizing the interactivity (bidirectionality) of the CD-ROM is put on the market. It has begun to be distributed.

By the way, since this kind of digital information is extremely easy to copy to other media and there is no deterioration caused by copying unlike analog information, the same information can be copied. It is very likely that the profits of the manufacturer will be harmed. That is, if a large-capacity rewritable magneto-optical disk or magnetic disk device is owned, the CD-ROM can be obtained with only a little knowledge of DOS commands.
It was easy to copy the contents of.

As described above, in most cases, the manufacturer prohibits the rental of digital information media of this type because a sufficient security check cannot be performed.

However, as the end user, the price of this kind of software at present is expensive, and whether the software really matches what he wants,
Or, he often hesitates to purchase until he can confirm that it can be used with his own hardware.

Regarding this point, a large number of software whose functions are limited are stored in a CD-ROM and sold at a low price, and the end user sends a payment for the desired software to limit the functions. A new software distribution method is being realized in which the code to be released is notified.

[0008]

However, the above-mentioned software distribution method cannot be said to sufficiently reflect the characteristics of the software.

[0009] In other words, in the method of releasing the above-mentioned function restriction, most of the money is sent in a lump sum, and this money is inevitably expensive. For example, I want to see a scene of a movie for a while. For example, if you want to use spreadsheet software for only one week, it is difficult to manage the charge according to the usage amount.

Regarding this point, in Japanese Patent Publication No. 6-19707, the usable amount of money is registered in the IC card in advance, and when the paid software is used, the usable amount of the IC card is registered in the system. Has proposed a method of subtracting the balance each time the software is used.

The present invention is a step further than these prior arts, and proposes a structure for increasing the security of the security circuit and connecting the card and the software reproducing device.

If an IC card is used, the PCM
The card may be a CIA-compliant card with a built-in card-sized memory, or may be a card that can be inserted into the housing as a board of a personal computer.

The adapter 1041b may be directly provided at the rear end of the software management card 1401, or may be provided at the front end of the cable pulled out from the rear end of the software management card 1401. (Overall Image of Software Distribution Form Using the Present Invention) FIG. 1
6 shows an overview of software distribution realized by the present invention.

Although the connection form of each case and the card has been described with reference to FIGS. 8 to 14, here, for convenience of description, the case of using the method of FIG. 4 will be described. First, an end user goes to a store 27 or the like (may be a mail order) and purchases a CD-ROM as a software storage medium 100 in which software is stored. At the same time, the software is reproduced by the own software reproduction device 1
The operation application disk 26 such as the driver software is purchased so that it can be played back with No. 03. Here, the operation application disk 26 is in the form of, for example, a floppy disk, and this may be used as an external user information storage medium. Further, although the CD-ROM stores a plurality of software, the selling price of the CD-ROM itself is very set because the CD-ROM is not a sales system for selling out the CD-ROM. Also, the store 27 may be a rental store.

That is, in the present invention, all the software stored in the CD-ROM is encrypted, and when the software is decrypted and reproduced, the SD circuit 3 as a software managing means which is maintained with high security. Is mandatory. And, as will be described later, a fee collection system according to the amount of software used is fully equipped. Therefore, the CD
-Even if the encrypted data stored in the ROM itself is copied to another medium, it is meaningless by itself.
Even if the OM is used as a rental system, the profit of the software provider will not be reduced if the charge collection system corresponding to the usage amount is complete.

When the end user wants to reproduce the software stored in the CD-ROM (100) by his or her own software reproducing device 103, the CD-ROM 10
0 and the operation application disk 26 are loaded into the software reproducing device 103, respectively.

Then, a communication application (this application may be provided as an operation application) installed in the software reproducing device 103 is started up, and a modem (MODEM) management center (HOST) which is the transmitting / receiving means 104 is activated. Send a request to use the software you want to use. On the other hand, the management center (HOST) searches whether the end user's account is registered as an account managed by the management center (HOST). If this account is valid, the software playback device 1 is sent through a public line or the like.
Permission command (key information) is encrypted to 03 and sent.

Upon receiving the permission command, the software reproducing apparatus 103 reads the CD-ROM 100,
The data is decoded by the SD circuit 3 and displayed on the CRT as an output device. In this way, the software desired by the end user can be reproduced. Here, in the operation of the software, the usage status is stored as user information in the work area (memory) of the software reproducing device 103. This user information is once encrypted by the SD circuit 3 and the operation application disk is used. 26. At the same time, the software reproducing apparatus 103 sends the user information to the management center (HOST).

At the management center (HOST), according to the user information received from the software reproducing apparatus 103,
A process of deducting a charge according to the usage amount used by the end user from the account of the end user of the financial institution (BANK) and transferring the fee to the account of the software provider (for example, CD-ROM sales company 1601) is performed.

As described above, according to the present invention, not only the software stored in the CD-ROM but also the user information generated by the operation of the software is encrypted and output to the outside. Unauthorized use of can be prevented.

In the embodiment described above, the software is supplied to the software reproducing device 103 by C
It is needless to say that the software is not limited to a tangible medium such as a D-ROM and may be software obtained as communication data from a host computer via a high-speed communication system.

[0066]

According to the present invention, by implementing various housing housing structures or card housing structures for the encryption / decryption means and the transmission / reception means, it becomes possible to collect software charges according to the usage amount. , A new software distribution system can be realized.
