Problems solved by technology

[0007] (1) The price of software storage media is too high
[0008] (2) There is no guarantee whether the software sold is fully suitable for the user's needs
[0009] (3) There is no guarantee that the software storage medium sold can be used on the hardware owned by the user
This brings the problem that software manufacturers or sellers cannot obtain reasonable benefits.

Embodiment 2

[0071] Fig. 2 is a system overall structure diagram of the application key authentication device.

[0072] The system has a communication modem connected with the software copying device, and connects the software copying device and the center 4 through a communication line.

[0073] In addition, in this preferred embodiment, for the sake of simplicity, the encoding software is usually stored in a CD-ROM, of course, these software can also be obtained as communication information.

[0074] Structure of software copying device

[0075] In this figure, the transmit-receive circuit 6 is an implemented module within the present invention. In this embodiment, the sending-receiving circuit 6 can be in the form of a board or a card, and it can be installed in the software duplication device in a fixed manner, or it can be an IC card, which can be arbitrarily installed in the card slot of the software duplication device. dismantle. The sending-receiving circuit 6 is installed in th...

Abstract

Through the use of user-unique information, the present invention prevents the improper use of software. The device is equipped with a software storage medium for storing software with encoded characters, graphs, images, or sound etc; an input characteristics detection section for detecting the characteristics of input operations performed by a user; a management center for encoding input characteristics detected by the input characteristics detection section and for generating consent information, and a comparison section for comparing the consent information generated by the management center with the input characteristics detected by the input characteristics detection section.

Description

technical field [0001] The invention relates to a key identification method and identification device. Background technique [0002] The present invention relates to a technology applicable to computer programs or software, such as copyrighted image materials, applicable to digital information software distribution systems. [0003] Recently, the technology of storage media for storing software has been significantly improved, and media such as CD-ROMs that can store large amounts of digital information have appeared on the market. Accordingly, it is expected that computer programs, images, sounds, and the like can be digitized and stored in large-capacity storage media, and these storage media can be sold as commodities. [0004] In other words, copyrighted image material provided in the form of video tapes is now stored on CD-ROM and sold, or game software is stored and distributed in the market using the interactive (two-way) feature of CD-ROM . [0005] Incidentally, ...
