System for generating an incrementally completed security mark

摘要

A system (10) for generating an incrementally completed security mark (20′″) includes a computer-readable medium encoded with a computer program. The computer program includes computer readable code for selecting a carrier object (20, 20′, 20″, 20′″); computer readable code for selecting a number of steps in a workflow associated with the carrier object (20, 20′, 20″, 20′″) and a security level for each step in the workflow; computer readable code for determining available carrier object candidate areas (T₁, T₂, T₃, T₄, T₅) to which to write information at each step in the workflow; and computer readable code for determining a number of bits to be input at each step in the workflow based upon the respective security levels and the available candidate areas (T₁, T₂, T₃, T₄, T₅). The system further includes memory and a processor operatively coupled to the memory and to the computer-readable medium.
