INFORMATION-EMBEDDING APPARATUS, MEDIUM FOR STORING INFORMATION-EMBEDDING PROGRAM, INFORMATION-EMBEDDING SYSTEM, INFORMATION-READING APPARATUS, MEDIUM FOR STORING INFORMATION-READING PROGRAM, AND INFORMATION-READING SYSTEM

摘要

An information embedding apparatus, a recording medium for storing an information embedding program, an information embedding system, an information reading apparatus, a recording medium for storing an information reading program and an information reading system are provided to overcome difficulty in embedding information caused by a difference between printers or between information embedding modes and easily select a first embedding mode according to a printer. An information embedding apparatus includes a first embedding unit(20), a second embedding unit(22) and an instruction unit. The first embedding unit is capable of printing print data using a printer(54) and embeds first information in a first embedding mode selectable according to the printer. The second embedding unit is capable of printing the print data through the printer and embeds second information which specifies the first embedding mode in a fixed second embedding mode irrespective of the printer. The instruction unit instructs the printer to print the print data in which the first information and the second information are embedded by the first embedding unit and the second embedding unit.
