Patent number: 10943421Abstract: An identification device of the present invention determines authenticity of an article with an anti-counterfeiting medium varying in a pattern of observed light depending on changes in light characteristics of radiated light, using the anti-counterfeiting medium. The identification device includes a similarity calculation unit that determines the degrees of similarity between a plurality of captured image data of the anti-counterfeiting medium obtained with differences in the light characteristics of the radiated light and reference image data corresponding to the light characteristics; and an authenticity determination unit that determines whether the degrees of similarity determined for the individual light characteristics exceed thresholds set corresponding to the individual light characteristics to make an authenticity determination on whether the anti-counterfeiting medium is genuine.Type: GrantFiled: September 11, 2018Date of Patent: March 9, 2021Assignee: TOPPAN PRINTING CO., LTD.Inventors: Takashi Okada, Tomohito Masuda, Eri Miyamoto, Kota Aono, Shogo Fujita

Patent number: 10300731Abstract: An anti-counterfeit medium, a method for manufacturing the same and a method for preventing counterfeiting are provided. The anti-counterfeit medium includes a retardation layer having birefringence and a reflection layer, and identification data is recorded in the anti-counterfeit medium. The identification data is divided into a plurality of partial images, and a plurality of transparent areas which correspond to the plurality of partial images are disposed adjacent to each other in the same plane so as to form the retardation layer, the plurality of transparent areas having optical axes which are oriented in different directions from each other in a rotation direction. The identification data includes biometric information.Type: GrantFiled: April 4, 2018Date of Patent: May 28, 2019Assignee: TOPPAN PRINTING CO., LTD.Inventors: Mihoko Ohkawa, Hideki Ochiai, Kota Aono, Yuki Kotegawa

Patent number: 10189293Abstract: An anti-counterfeit medium includes a portion having optical transparency, a retardation layer facing the portion and including regions whose slow axis directions are different from each other, and a polarizing layer facing the retardation layer at a position of the portion. The anti-counterfeit medium includes only the polarizing layer as a polarizer. A portion out of the anti-counterfeit medium where the portion, the retardation layer, and the polarizing layer form a stacked structure has optical transparency.Type: GrantFiled: August 28, 2013Date of Patent: January 29, 2019Assignee: TOPPAN PRINTING CO., LTD.Inventors: Hideki Ochiai, Mihoko Nagayoshi, Kota Aono, Yuki Kotegawa

Patent number: 10046359Abstract: An oriented film includes first to fourth regions having first to fourth orientation angles. First polarized light having a first intensity is radiated onto the first and second regions of a photosensitive film. Second polarized light having a second intensity is radiated onto the second and third regions of the photosensitive film. Third polarized light having a third intensity is radiated onto the first to fourth regions of the photosensitive film. The polarization angles of the first to third polarized light are different from each other. The second polarization angle is larger than the first polarization angle. The third polarization angle is larger than the second polarization angle. The polarization angle of the second or third polarized light radiated onto the third region is less than the third alignment angle.
