A technique used on CD and DVD discs to prevent the contents being copied and/or re-used. Technologies used include watermarking, signatures on disc and encryption.
or copy prevention is any technical measure which prevents the duplication of information. It can be found on videotapes, DVDs, CDs, computer software discs, or video game discs.
A software lock placed on a computer program by its developer to thwart piracy. This preventative measure was widely used in the mid-1980s but later abandoned by many developers because of numerous customer complaints.
Used on 99 percent of DVDs to prevent copying to VHS or other video formats. Home copying of DVDs to other formats is now so difficult it's practically impossible, thanks to several different copy protection procedures employed by manufacturers. See also Macrovision.
ways to prevent or limit the illegal copying of software.
Many commercially sold CDs contain a system which is intended to stop the disc from being copied. When an attempt to copy a copy-protected disc is made, the CD burner usually displays an error message.
A sly technique employed by hardware vendors to combat software piracy by continually changing the size and compatibility of disk drives (from 160 K to 320 K to 360 K to 1.2 MB to 720 K to 1.44 MB to 2.88 MB.).
storage: Security added to software so users cannot simply or easily make copies. Designed to prevent illegal distribution of software, it also inhibits easy use of hard drives and thwarts backups.
Technological protection that prevents a user from copying a digital file.
A software strategy employed by program developers to make it difficult to copy software illegally.
A system for preventing the unauthorized reproduction of copyrighted media like movies or music. The DVD format includes both digital and analog forms of copy protection; the VHS format uses analog copy protection. You will most likely not be able to copy commercial DVDs or commercial VHS tapes to your DVR's hard drive.
Techniques used to prevent the unauthorized copying of software.
This is where a software producer uses some system of data encoding (or whatever) to prevent program disks and tapes from being copied. The idea is to prevent people from copying software bought by their friends rather than buying their own (legitimate) copy. Some disks are copyable, but the copies will not load and run properly. Another method, and one that is popular with the more expensive programs, is to have a 'dongle', or 'security key'. This is an electronic device which connects to one of the computer's ports. Dongled software can be copied, but will not run without the right dongle connected to the computer. The use of copy protection and similar methods by the software publishers is quite understandable. On the other hand, it can be inconvenient to users who are presumably paying any extra costs involved.
Any method, either physical or software-based, of preventing illegal duplication of audio programs, video programs and computer software.
Copy protection, also known as copy prevention or copy restriction, is any technical measure designed to prevent duplication of information. Copy protection is often emotionally debated, and is thought to sometimes infringe on some users' property rights: for example, the legal right to make a backup copy of a videotape they have purchased, to install and use computer software on multiple computers, or to upload their music into their digital audio player for easier access and listening.
