微机软件防拷贝保护方法及配套技术

MICRO-COMPUTER SOFTWARE COPY PROTECTION METHOD AND NECESSARY TECHNIQUES

本文研究的是PC系列微机的软件防拷贝问题。本文分析了一些常见的防拷贝方法,提出了一种廉价而又高性能的新方法。此法通过格式化出恰含有整数个信息位的磁道,在软盘中生成一种不可拷贝的、不可预知的、稳定可靠的密码用以有效地阻止拷贝软件和拷贝机、拷贝卡对盘中程序的复制。文中还介绍了其应用方法及所需的防分析、防跟踪、防修改、程序防拷版的硬盘安装等配套技术。

This paper deals with the PC series micro - computer software copy protection problem. After analysing some common copy protection methods, the paper proposes a new method with low price and high performance. By formatting cylinders to contain integral data bits, it creates an uncopyable, unpredictable,reliable cipher on the diskette which will hold programs in need of copy protection to prevent any copy software and hardware tools from making executable copies of the programs . This paper also introduces the new method ' s application and some necessary techniques to protect against analysing, tracing, modifying, and install the copy - protected programs in fixed disks, etc.
