17) The Bear Corporation uses a tool that embeds a code into all of its digital documents. It then scours the internet, searching for codes that it has embedded into its files. When Bear finds an embedded code on the internet, it knows that confidential information has been leaked.

a digital watermark.

Explanation:

A digital watermark is a kind of marker covertly embedded in a noise-tolerant signal such as 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.
