A method of checking a sheet as to forgery thereof, the sheet being provided with an electronic circuit chip from or in which information can be read out or written and having visible information. The method includes a step of encrypting the visible information of the sheet and storing the encrypted visible information in the electronic circuit chip, and a step of determining discriminatively the authenticity of the sheet by comparing the visible information of the sheet with the information stored in the electronic circuit chip.

摘要:
A non-contact identification semiconductor device is provided with a semiconductor chip including a receiving circuit that receives an inquiry to the non-contact identification semiconductor device, a memory that stores identification information of multiple bits and a sending circuit that sends the identification information. An antenna coupled to said semiconductor chip receives the identification information from said semiconductor chip and transmits the identification information outside of said non-contact semiconductor. The long side length of the semiconductor chip is not greater than 0.5 mm in plane dimension, and the identification information is stored by a pattern printed by an electron beam.
摘要:
This Application is intended to provide a method for effectively protecting paper or film-form media against forgery. This can be achieved by, for example, embedding in a paper or film-form medium a thin semiconductor chip up to 0.5 mm square, equipped with an antenna, and characterized in that the side walls of the semiconductor chip are formed using oxide films, and in that multiple such semiconductor chips are separated by etching. Limiting the size of these semiconductor chips to 0.5 mm or less enables improvement against bending and concentrated loads, and separating the semiconductor chips by etching results in semiconductor chips free from cracking and breakage. Also, the oxide films constituting the side walls of the semiconductor chips prevents short-circuiting at edges during connection to the respective antennas. Thus, simplified processes can be adopted.
