Abstract
A computer-executable information tracking method, an image forming apparatus, an information processing apparatus, and a program to adequately track the information flow of a paper document are disclosed. The method includes a first detecting step of, whenever an input or output of information is performed using a paper as a medium, detecting paper identification information that uniquely identifies the paper from other paper; a storing step of associating and storing the paper identification information with information regarding the input or output of information in a recording device; a second detecting step of detecting the paper identification information of a designated paper; an information searching step of searching for the information regarding the input or output of information on the designated paper by comparing the paper identification information of the designated paper with the paper identification information stored in the recording device.
