StarForce is a powerful multi-level protection system, which is designed and developed to help developers or publishers to protect their CD/DVD-ROM applications and files from illegal piracy. Most modern copy protection systems only encrypt executable files and bind them to genuine CDs in some way. The multi-level full-function protection technology pioneered by StarForce Professional Edition not only works on executable files, but also encrypts any non-executable files in the application. With this system, developers can protect local games, entertainment and education software, electronic encyclopedias, office applications and so on in a unique way. StarForce can also protect data files that contain localized information. Users with bad intentions can't access this information, so they have to create new local information for their pirated distribution. The extra time and money will greatly reduce the profit of piracy.

In many modern protection technologies, various signs similar to "digital signatures" that cannot be copied are loaded on the media surface with special burning equipment. These "digital signatures" will not be transferred when copying this kind of optical disc with ordinary CD burning program, so that an error will occur during operation. However, there are many problems in this protection method. The first point is that the glass master it uses can only be run and produced on a copying machine with special recording equipment. Secondly, there are many professional recording programs that can read and write sectors one by one in R AW mode, and copy the original disc completely, which makes "digital signature" meaningless. In addition, the use of "digital signature" will change the physical structure of the media, which may cause compatibility problems between the protected disk and the user drive. StarForce protection system does not need to load any marks on the surface of the media, but identifies genuine products by reading and analyzing the physical parameters of the media. These physical parameters cannot be duplicated with each other because they depend on the complex and unique structure of the glass master. If the optical discs with the same content are made from different glass master discs, their physical parameters are also completely different. StarForce technology uses the physical parameter information of optical disc to generate a password for it with a unique algorithm. This password is used by the protection module and embedded in the executable file of the application program to identify the genuine CD. When running the protected program, you must put the original into the CD-ROM drive to check whether the password information in this protection module is consistent with the physical parameters of the CD-ROM. This password itself can be printed on the software package, on the back of the CD-ROM or posted on the product website. The client-server communication technology applied in the protection process ensures the security of the encryption algorithm very reliably. The key encryption operations are completed on a remote server of StarForce, and no foreign intruders can access the system.

StarForce encryption technology is a technology developed by Russian technicians, which can identify encrypted CDs and illegal copies of CDs. So far, this technology has not been really cracked. StarForce can also identify the difference between mirror files made by CloneCD, CDRWin, BlindWhite and the original. Nowadays, many pirated games are composed of mirror files of genuine CDs and virtual CD-ROM software. In fact, the software that mirrors the CD-ROM drive can crack many technologies. When there is a genuine source disk that is mirrored, it can be recognized by encryption technology as an illegal copy. These manufacturers who make mirror software will study and improve their encryption technology until the virtual CD will not be regarded as illegal copies by the encryption technology adopted by the software-in this way, a new version of the virtual CD-ROM is born. However, it is said that StarForce, which made StarForce software, has reached an agreement with several manufacturers of virtual CD-ROM software, requiring that these virtual CD-ROM software do not provide complete virtual support for optical discs produced by StarForce encryption technology. In other words, another way to make piracy has been blocked. But it also reveals to us that StarForce is not unbreakable. Once a virtual CD-ROM software manufacturer fails to abide by this agreement, a large number of pirated games will appear again.

StarForce is a CD encryption technology purchased from Russia by Universal Star Company (responsible for product agents of Daewoo, Yujun, Fenglei, Odin and Hongyu Game Company) and the above five companies, and it is said that the encryption power is the second in the world. This technology writes encrypted information to the last CD of the game, that is, the CD that must be put into the CD-ROM when running the game, including a set of codes of cdkey type. This kind of CD can't be copied and virtualized. The manufacturer of StarForce technology has signed contracts with large virtual CD-ROM drive manufacturers and recording software manufacturers, and does not provide virtual and recording support for StarForce. Therefore, StarForce encrypted disks cannot be virtualized and copied by software. StarForce has two major defects. 1. It can be cracked by violence. Using cpukill software, the cpu occupancy rate reaches 1, and then running the main program of the game, you have the opportunity to avoid detection and enter the game, but it takes a lot of time, about half an hour, but also a few minutes. 2. Many kinds of DVD-ROM and CDRW-ROM, some CDROM can't detect encrypted data, so they can't enter the game. It is also possible that sometimes you can enter, and sometimes you can't. If it is normal, the test can pass in 3 seconds. The principle of StarForce
