た。Conventional unauthorized copy prevention methods, when recording software on a flexible disk, make the physical format of the software a special format that is different from the physical format of normal software. When this software is started, a program is installed to check the physical format of this software, so if unauthorized copying is done in the form of a normal software physical format, it will immediately detect that the physical format is different. The ability to stop use was used to prevent unauthorized copying.

ある。The unauthorized copy prevention method of the present invention is a method for preventing unauthorized copying of software sold using a flexible disk as a medium, which includes a destruction step of physically destroying a part of the flexible disk, and a destruction step of physically destroying a part of the flexible disk. a storage step of storing the faulty sector destroyed in the read destruction step; a write step of writing the data of the faulty sector together with the software into a storable sector based on the destroyed fault state stored in the storage step;
A state reading step in which the software reads the states of all sectors of the flexible disk in which it is stored as the first operation upon activation, and a result of the state reading step and the already stored data of the faulty sector. The configuration includes a state inspection step of comparing and checking whether or not they match, and a software start/stop step of stopping the start of the software when a mismatch is detected in the state check step.

ィスクが作成される。Next, in step 3, a read test is performed on all sectors of the flexible disk, and the faulty sectors destroyed due to the scratches are memorized, and in step 4, the scratched sectors are set as spares in the file allocation table so that they are not used for file management purposes. In step 5, the software is copied to the flexible disk, and in step 6, the status of the faulty sector is written in the faulty sector registration table of the software. As a result, a flexible disk that is protected against unauthorized copying is created.

Next, in step 8, the status of all sectors of the actual flexible disk is read and compared with the failed sector information read in step 7. As a result of this comparison test, if it is determined that they match, the software is activated for normal operation in step 9. In addition, as a result of comparative testing,
If it is determined that there is a mismatch, the user is notified in step 10 that the flexible disk has been illegally copied and the software will stop starting.
Stop the software from starting.

能となる効果が有る。As explained above, the present invention physically scratches the magnetic material-coated surface of a flexible disk, then stores the faulty sectors destroyed by the scratches, and stores the faulty sectors as memorable sectors based on the stored faulty state. The data of this faulty sector is written along with the corresponding software, and the next time the software is used, the first operation when the software is started is to read the state of all sectors of the flexible disk that has memorized itself, and then read the state. By comparing the results obtained with the data of the faulty sector that has already been stored and checking whether they match, it is possible to reliably detect unauthorized copying.
