Robust watermark

A watermark that is designed to prove authenticity of an image or other media. A fragile watermark is destroyed, by design, when the cover is manipulated digitially. If the watermark is still intact, then the cover has not been tampered with. Fragile watermark technology could be useful in authenticating evidence or ensuring the accuracy of medical records or other sensitive data.

A channel that conveys information by altering the performance of a system component or modifying a resource’s timing in a predictable manner. A covert channel in which one process signals information to another by modulating its own use of system resources in such a way that this manipulation affects the real response time observed by the second process. Covert channel in which one process signals information to another process by modulating its own use of system resources (e. g. , central processing unit time) in such a way that this manipulation affects the real response time observed by the second process.
