ABSTRACT:
A system and method including cameras for monitoring objects such as documents, at multiple locations, and for recording the objects' movement through space and time. The objects are marked with unique identifiers, and the invention is adaptable for recording and recognizing the objects' development using character recognition. A center receives the information from the cameras, and that information is searchable. Advantageously, the unique identifiers are printed with ink that is invisible unless it fluoresces or phosphoresces, the digital cameras include an ultraviolet flash to cause the identifiers to fluoresce or phosphoresce at a certain wavelength, and the cameras are equipped with filters to filter out wavelengths other than the certain wavelength. Packages or pads of pre-marked blank paper are adaptable for use with the present invention.
