   Printer tracking dots. Printer tracking dots, also known as printer steganography, DocuColor tracking dots, yellow dots, secret dots, or a machine identification code ( MIC ), is a digital watermark which many color laser printers and copiers produce on every printed page that identifies the specific device that was used to print the document.

   en.wikipedia.org/wiki/Locard's_exchange_principle

   Dr. Edmond Locard (1877–1966) was a pioneer in forensic science who became known as the Sherlock Holmes of Lyon, France. [ 1] He formulated the basic principle of forensic science as: "Every contact leaves a trace". It is generally understood as "with contact between two items, there will be an exchange."

5. Field trace - Wikipedia

   en.wikipedia.org/wiki/Field_trace

   The trace form is used in algebraic number theory in the theory of the different ideal. The trace form for a finite degree field extension L/K has non-negative signature for any field ordering of K. The converse, that every Witt equivalence class with non-negative signature contains a trace form, is true for algebraic number fields K.

6. Trace (linear algebra) - Wikipedia

   en.wikipedia.org/wiki/Trace_(linear_algebra)

   Trace (linear algebra) In linear algebra, the trace of a square matrix A, denoted tr (A), [1] is defined to be the sum of elements on the main diagonal (from the upper left to the lower right) of A. The trace is only defined for a square matrix ( n × n ). In mathematical physics texts, if tr (A) = 0 then the matrix is said to be traceless.

7. Trap and trace device - Wikipedia

   en.wikipedia.org/wiki/Trap_and_trace_device

   A trap and trace device shows what numbers had called a specific telephone —i.e., all incoming phone numbers. A pen register rather would show what numbers a phone had called, i.e. all outgoing phone numbers. The two terms are often used in concert, especially in the context of Internet communications. They are often jointly referred to as ...
