The original secure cryptoprocessor was designed for copy protection of personal computer software (see US Patent 4,168,396, Sept 18, 1979) [5] to provide more security than dongles could then provide. See also bus encryption. Hardware cloning, where the dongle is emulated by a device driver, is also a threat to traditional dongles.
Transmitting device checks before sending that receiver is authorized to receive the data. The data is encrypted during transmission to prevent eavesdropping. Serial Copy Management System Records in the sub code data bits that expresses whether the media is copy allowed(00), copy once(10) or copy prohibited(11). Traitor Tracing
A dongle (center, in white) allowing an ethernet cable (left, in grey) to be connected to a Thunderbolt port on a laptop (right). A dongle is a small piece of computer hardware that connects to a port on another device to provide it with additional functionality, or enable a pass-through to such a device that adds functionality.

Copy protection for computer software, especially for games, has been a long cat-and-mouse struggle between publishers and crackers.These were (and are) programmers who defeated copy protection on software as a hobby, add their alias to the title screen, and then distribute the "cracked" product to the network of warez BBSes or Internet sites that specialized in distributing unauthorized ...
Since 2010, clone computing, in the sense of replicating a session on a host computer in a virtual instance in the cloud, has been introduced. This allows the user to have access to a copy of their PC's desktop on any other computing device such as a tablet computer, a personal computer running any operating system, WebOS, smartphones, etc.
Clonezilla Server Edition (SE) can clone many computers at the same time using multicast technology over a computer network. [15] Multicast support is provided by UDPCast tool. [4] Since such an environment is difficult to configure, users can download a Live disk that provides the operating system with all the necessary configurations already ...
Disk cloning is the process of duplicating all data on a digital storage drive, such as a hard disk or solid state drive, using hardware or software techniques. [1] Unlike file copying, disk cloning also duplicates the filesystems , partitions , drive meta data and slack space on the drive. [ 2 ]
When ELM Electronics sold version 1.4 of its ELM327, it did not enable the copy protection feature of the PIC microcontroller. Consequently, anyone who had bought a genuine ELM327-v1.4 could use a device programmer to read ELM's proprietary microcontroller firmware as a binary blob. Pirates could trivially produce an ELM327 clone by purchasing ...
