Patent number: 11551475Abstract: A non-transitory computer-readable medium encoded with a computer-readable program which, when executed by a processor, will cause a computer to execute a method of authenticating a 3-D object with a 2-D camera, the method including building a pre-determined database. The method additionally includes registering the 3-D object to a storage unit of a device comprising the 2-D camera, thereby creating a registered 3-D model of the 3-D object. Additionally, the method includes authenticating a test 3-D object by comparing the test 3-D object to the registered 3-D model.Type: GrantFiled: March 15, 2020Date of Patent: January 10, 2023Assignee: Purdue Research FoundationInventors: He Wang, Siyuan Cao, Habiba Farrukh, Reham Mohamed Aburas
