Patent number: 11962593Abstract: A principal database is described in which each entry includes one principal identity, and one or more alias identities that may each have an authorization scope. Principal identity attributes include a principal identifier and login credentials, and alias identity attributes include an authorization scope and login credentials. Responsive to successfully authenticating the user for a first application (a multiple-identity application), based on the alias identity login credentials, an access token containing both the alias identity attributes and the principal identity attributes is transmitted to the first application, causing the first application to grant a scope of access based on the authorization scope. Responsive to a request to authenticate the user for a second application (a single-identity application), the access token is transmitted to the second application without re-authenticating the user, causing the second application to grant a scope of access based on the principal identifier.Type: GrantFiled: August 24, 2021Date of Patent: April 16, 2024Inventors: Ricardo Fernando Feijoo, Thomas Michael Kludy

Patent number: 11726987Abstract: A technique involves normalizing identification of users (e.g., different customer organizations) across disparate local systems (e.g., different electronic platforms that provide different products and/or services). Such normalization of user identification enables a provider to accurately ascertain a particular user of multiple disparate local systems even when the multiple disparate local systems identify that user using different identification schemes. Accordingly, the provider is able to offer enhanced support to that user across the multiple disparate local systems. For example, with such normalization of user identification, the provider may employ a single authentication system across the various local systems thus enabling the user to authenticate via the same authentication process regardless of which local system the user attempts to access.Type: GrantFiled: November 17, 2020Date of Patent: August 15, 2023Assignee: Citrix Systems, Inc.Inventor: Ricardo Fernando Feijoo
