Patent number: 11863980Abstract: A System Platform establishes a Genuine User ID (“GUID”), creates a user profile for an Intended User, generates a unique data set based upon input associated with the user profile and a digital device it has registered to the Intended User. The output of the GUID in combination with the output of an algorithm in a provisioning application enables the digital device to respond to Access Requests at an Access Point. The response from the genuine Intended User's application on their genuine digital device produces a unique data package which combines the GUID, a device ID for the digital device and the output of the algorithm using the payload obtained from one or more data management sources. The unique data package can be tailored for many different uses by the intended user, including uses which are attended or unattended, with varying levels of security.Type: GrantFiled: July 2, 2021Date of Patent: January 2, 2024Assignee: SYQURX, INC.Inventors: Joan Ziegler, Richard Sergio Nassar, Darin Nelson, Neil Charles MacDonald, William James Templeton-Steadman, Mark A Villiott, Glen D Parker
