Patent number: 11899774Abstract: An authentication apparatus and a method to devise an authentication tool is provided for facilitating determination of authenticity or genuineness of an article with reference to a captured image or a purported primary image of an information bearing device on the article. The authenticity or genuineness of an article is determined with reference to whether a captured image is a primary image of an authentic information bearing device using a trained neural network. The neural network is trained using training images comprising imperfect images having varying degrees of image imperfections which are introduced under controlled conditions.Type: GrantFiled: March 1, 2019Date of Patent: February 13, 2024Assignee: INFOTOO INTERNATIONAL LIMITEDInventors: Tak Wai Lau, Wing Hong Lam
