A digital watermark is a kind of marker covertly embedded in a noise-tolerant signal such as an audio, video or image data.

It is typically used to identify ownership of the copyright of such signal.

"Watermarking" is the process of hiding digital information in a carrier signal; the hidden information should, but does not need to, contain a relation to the carrier signal.

Digital watermarks may be used to verify the authenticity or integrity of the carrier signal or to show the identity of its owners.

It is prominently used for tracing copyright infringements and for banknote authentication.

The Portable Document Format (commonly referred to as PDF) is a file format used to present documents in a manner independent of application software, hardware, and operating systems.

Each PDF file encapsulates a complete description of a fixed-layout flat document, including the text, fonts, graphics, and other information needed to display it.

Computer software, or simply software, is that part of a computer system that consists of data or computer instructions, in contrast to the physical hardware from which the system is built.

In computer science and software engineering, computer software is all information processed by computer systems, programs and data.

Computer software includes computer programs, libraries and related non-executable data, such as online documentation or digital media.

Computer hardware and software require each other and neither can be realistically used on its own.

In signal processing, data compression, source coding, or bit-rate reduction involves encoding information using fewer bits than the original representation.

Compression can be either lossy or lossless.

Lossless compression reduces bits by identifying and eliminating statistical redundancy.

No information is lost in lossless compression.

Lossy compression reduces bits by removing unnecessary or less important information.

A computer file is a computer resource for recording data discretely in a computer storage device.

Just as words can be written to paper, so can information be written to a computer file.
