Problems solved by technology

However, the additional hardware may cause the original performance of the computer to decline or cause damage to the computer hardware, and the computer may not work properly due to the failure of the additional hardware.
Some software developers use the installation floppy disk to prevent copying. After the software is installed, the installation information is written on the floppy disk, and it cannot be used on other computers.
However, the security of using the installation floppy disk for encryption is low, and the failure rate of the floppy disk itself is very high, so the encryption is not reliable

Embodiment Construction

[0013] The invention utilizes the network card and the encryption software to realize the encryption of the software and prevent the software from being copied and installed illegally. The encryption software consists of two parts, one is the encryption software management program, and the other is the encryption software application program. A unified encryption algorithm and password file are used between the two. The management program provides the application program with a password file of the same system after encryption. The application program can be placed in front of the application software (that is, the software to be encrypted and protected) by batch processing commands, or added to the application software by an external call method, or added to the application software by a library function call method. The management program is used by the software developer. Its main function is to pre-authorize and register the client computer, generate a password file accordi...

Abstract

This invention relates to a method for preventing non-authorized usage of software with MAC address, in which, a software development runner utilizes a ciphered software management program to convert the MAC of the customer end computer to a ciphered code and writes it to a ciphered code file to be provided to the customer, the customer end computer utilizes a ciphered software applied program to convert the local MAC address according to the same ciphered algorithm and compares it with the ciphered code fetched from the ciphered file, if they are the same, then the authorization is successful, which utilizes computer net cards to bind the ciphering applied software and a customer end computer, since each net card has an exclusive physical address in the world and if the address is bound, that means the software is bound onto the exclusive computer.

Description

technical field [0001] The invention relates to a method for preventing unauthorized use of software. Background technique [0002] Illegal copying and installation of software is a problem that plagues software developers. The usual preventive method is to encrypt the software and require the input of the serial number when installing. Although this method has certain effects, the serial number is easy to be cracked. Some software developers use a dongle to encrypt the software, which includes a hardware installed on the parallel port or USB port of the computer and supporting special software, and uses the software to read the logo on the additional hardware to judge whether the hardware exists. The purpose of protection, No. ZL02822040.4 invention patent promptly adopts the above-mentioned method. However, the additional hardware may cause the original performance of the computer to decline or cause damage to the computer hardware, and the computer may not work normally ...
