A file with activation key that needs to be installed in same directory as software; similarly, a disc media (often installation disc) may be required as key disk for activation. [1] Code Morphing Hiding intermediate code by means of code obfuscation so that execution logic is not visible. This method does not protect against runtime tracing. [2]
A software license is a legal instrument that governs the usage and distribution of computer software. [1] Often, such licenses are enforced by implementing in the software a product activation or digital rights management (DRM) mechanism, [2] seeking to prevent unauthorized use of the software by issuing a code sequence that must be entered into the application when prompted or stored in its ...
A Hardware keylogger for USB-Keyboards Hardware keyloggers are used for keystroke logging , a method of capturing and recording computer users' keystrokes, including sensitive passwords.

[ 1 ] [ 2 ] As businesses have increased demand for these drives, manufacturers are producing faster devices with greater data storage capacities.
There are potential weaknesses in the implementation of the protocol between the dongle and the copy-controlled software. For example, a simple implementation might define a function to check for the dongle's presence, returning "true" or "false" accordingly, but the dongle requirement can be easily circumvented by modifying the software to always answer "true".
Software crack illustration. Software cracking (known as "breaking" mostly in the 1980s [1]) is an act of removing copy protection from a software. [2] Copy protection can be removed by applying a specific crack. A crack can mean any tool that enables breaking software protection, a stolen product key, or guessed password. Cracking software ...
USB flash drives sometimes have a small switch, though this has become uncommon. An example of a USB flash drive that supported write protection via a switch is the Transcend JetFlash series. Secure Digital (SD) cards have a write-protect tab on the left side. Extensively, media that, by means of design, can't operate outside from this mode: CD ...
