DXR movie files now protected

Cops Crypto has over time been used on many different dataformats, bitmap files, database files and digital maps to mention a few.

The Copenhagen School of Dental Hygiene has recently released a fascinating CD-ROM illustrating the anatomy of the head by the use of Macromedia Director multimedia files (DXR files). Since these files are of standard format and can be read by a standard Macromedia browser, they chose to encrypt the files using Copís Crypto. The result is a CD that cannot be copied, containing encrypted data that cannot be used without the original CD-ROM.

No noticeable speed performance degradation was detected on the DXR files.
