Disc check
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.
When application starts, the LaserLock
code runs first, and checks that the original optical disc is in the
PC-drive. It checks that the LaserLock Physical Signature is in correct
place and has a correct size, and that the hidden good data are in
correct position.
Debug prevention 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.
Physical signature The
LaserLock physical signature is a number of corrupted sectors with
hidden good data, created with the development of a custom format on
the disc structure that can be identified only by the LaserLock
software. The physical signature is unique for every application that
is being protected.
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.
The physical signature is applied during the mastering process for CD-ROM and DVD-ROM and during the burning process for CD-R.
Although
mastering can take place only at one of the LaserLock Mastering
Licensees worldwide, you can press your optical disks at the pressing
factory of your preference. LaserLock stampers can be used as standard
stampers at every pressing factory.
