LaserLock is copy protection system that provides efficient anti-copy security for optical discs (CD-ROM, CD-R and DVD-ROM). LaserLock uses a combination of encryption software and a unique laser marking of "physical signature" on the optical disc's surface. For CD-ROM and DVD-ROM this is made during the special LaserLock glass mastering procedure in mastering-house, and for CD-R during burning procedure in customers premises.

LaserLock holds an American, an International, and European patens, it also holds patens in countries that are not covered by these patent offices such as Russia, Canada, Bulgaria, China, Australia and Egypt. See similar questions...

LaserLock uses its own proprietary tools to inject the LaserLock code into the executable. As a result of the "injection" process, the executable is encrypted. The LaserLock code that searches for the LaserLock physical signature on the disc, is protected by several layers of debug prevention code, making reverse engineering practically impossible. The physical signature is unique for every application that is being protected. See similar questions...

The LaserLock for CD-ROM, and CD-R occupies 20MB of disc space, when the LaserLock for DVD-ROM occupies 40MB of disc space In CD-ROM this size can be reduced down to 5MB in special cases (such as shape CDs or business-card CDs) but we highly recommend the maximum size, which achieves maximum security. In case your application occupies the entire 650 MB capacity of a standard CD-ROM, CD-Rs with bigger capacity (700 MB) can be used for the pre-mastering procedures. See similar questions...

LaserLock for floppy discs was introduced in 1990. The use of this specific medium in the software market has declined so significantly the last few years, so LaserLock focused on optical disc and download technology. See similar questions...

The only way that we could use LaserLock for data protection is if the data were somehow encrypted and there is an executable that decrypts them. In this case we can protect the executable that makes the decryption. So, if someone copies the data files, he can not use them because they are encrypted and if he copies the protected executable it will not work without the LaserLock disc inside his drive.

Every customer can ask LaserLock to open an account in the LaserLock on-line tools in order to do the LaserLock pre-mastering in-house. All the LaserLock Mastering Licensees have been trained to use the LaserLock pre-mastering on-line tools. See similar questions...

LaserLock can protect the PC part of mixed mode CDs. Audio tracks cannot be protected and are not affected by the protection. LaserLock supports standard DVD-ROMs (DVD-5), Mixed Mode DVDs and generally any format in which the first track is the data track in mode 1. LaserLock pre-mastering and mastering does not affect the data files of the customer. Extensive testing of the pre-master DVD-R assures that the behaviour of the pre-master DVD-R is the same as the one of the customer's master DVD-R. See similar questions...

LaserLock is meant to protect the main executable of an application. Should a customer need to protect his setup program, LaserLock could be applied to the setup executable. The customer must keep in mind that in the case he chooses to protect the setup executable the original CD-ROM will only be checked for authentication during the installation process. The customer must also keep in mind that the setup executable should be unique. See similar questions...

The user can copy the contents of a optical disc protected with LaserLock, to his hard disk drive, but he will not be able to run the application without the original disc inside his drive. See similar questions...

The user can copy the contents of a disc over the Internet, but he will not be able to run the application without the original disc inside his drive, because the LaserLock physical signature cannot be transferred over the Internet. See similar questions...

LaserLock can protect multiple executables using the same disc (e.g. The Direct3D and the Glide version of a game). The only restriction is that the executables should not be launched simultaneously. Another case in multiple executables is when a protected executable calls another one. LaserLock can protect both executables, but the delay of the multiple authentication process may be annoying for some users. See similar questions...

The LaserLock module can be installed on any mastering facility with encoder from Eclipse or Singulus (ODME/Media Morphics) See similar questions...

Our latest LaserLock version has been tested under the latest advanced copying software. This includes: The results were extremely positive. Some of these s/w cannot even create a copy CD at all. From those who can do so, the copy has a very unstable behaviour, virtually meaning that it cannot run in almost any CD and DVD drive. See similar questions...
