Patent number: 11621955Abstract: A method, system and computer program product for delivering a digital identity document. A request is received to purchase a digital identity document from a user by a system. An acquisition uniform resource locator (URL) with parameters corresponding to the identity of the user and the requested digital identity document is created and provided to the user. The user utilizes the received URL to communicate with an issuer to request the digital identity document. The system then receives the requested digital identity document in encrypted form from the issuer. The system then delivers the encrypted digital identity document to the user. In this manner, the system can deliver to the user an identity document in digital form that has been vetted as trusted in a secure manner thereby reducing the number of occurrences in providing improper identity documents as well as lessening the ability to generate falsified identity documents.Type: GrantFiled: April 5, 2016Date of Patent: April 4, 2023Assignee: International Business Machines CorporationInventors: William F. Abt, Jr., Daniel A. Gisolfi, Asher C. Johnson, Richard Redpath

Patent number: 11250173Abstract: A master digital copy of a registration is transmitted. The registration is proof that a physical object has been registered with a registration authority. A valid peripheral digital copy of the registration is received. The valid peripheral digital copy of the registration was made from the master digital copy of the registration and is incapable of being used to make other valid digital copies of the registration.Type: GrantFiled: August 26, 2019Date of Patent: February 15, 2022Assignee: International Business Machines CorporationInventors: Daniel A.

Patent number: 10972274Abstract: An example operation may include one or more of connecting, by an identity server, to a blockchain configured to store an identity trait of a user, retrieving, by an identity server, the identity trait from the a blockchain, establishing, by the identity server, a trust group homomorphism digital signature algorithm (DSA) for the user associated with the identity trait based on a public key PK1, creating, by the identity server, a zero-knowledge proof function with a public key PK2 based on a DSA member of the trust group homomorphism for witness data, providing, by the identity server, the witness data to a challenger for the zero-knowledge proof function, and receiving, by the identity server, a validation of the user as a proved user based on execution of the zero-knowledge proof function based on the witness data.Type: GrantFiled: August 29, 2018Date of Patent: April 6, 2021Assignee: International Business Machines CorporationInventors: Richard Redpath, Daniel A.

Patent number: 10812271Abstract: A method, system and computer program product for privacy control. A unique identifier for each data element of a group of data elements (e.g., driver's license contains a group of data elements, such as name, driver's license number) is created. These identifiers may be stored along with documentation (e.g., label) of the associated data elements in a manifest file. Alternatively, the identifiers may be stored in a file outside of the manifest file. In this manner, by utilizing a data element identifier which corresponds to a random number, security of privacy information is improved as one would only be able to obtain such sensitive information by obtaining such an identifier. Furthermore, the user only needs to send the requested data elements, as opposed to all the data elements of the group of data elements, to the challenger. In this manner, the user is preserving the security of other privacy information.Type: GrantFiled: May 17, 2019Date of Patent: October 20, 2020Assignee: International Business Machines CorporationInventors: William F.

Patent number: 10559049Abstract: The method utilizes a passport identification number as an element of a homomorphic encryption used to stamp a passport with country entry/exit data to form a digital representation of a subset of information in the passport. As a result, exchange of the digital representation is permitted to allow a selective transfer of information without exposing a user-sensitive passport identification number. The homomorphic encryption comprises a support for exposing a trusted photo and a trusted group containing country travel entry and exit information. The digitally signed passport stamp may then be used to provide verification of the individual by ensuring linkage to that user's passport. The individual's identity and passport verification may occur unconnected, i.e., without having to connect to a central database.Type: GrantFiled: April 19, 2016Date of Patent: February 11, 2020Assignee: International Business Machines CorporationInventors: William F.

Patent number: 10084606Abstract: A method, system and computer program product for facilitating the generating of digital identity documents. A system receives a selection and initialization of properties (e.g., identity attributes, document type, alternate views, an acquisition uniform resource locator (URL)) to be used in a digital identity document (e.g., driver's license). The system then builds a template using the selected properties. The system may then present a list of built templates to a user/verifier to be used in generating a corresponding digital identity document. Upon receiving the selected template, the system provides the acquisition URL associated with the selected template to the user/verifier to be used by the user/verifier to request the corresponding digital identity document from the issuer. After receiving the digital identity document constructed by the issuer from the issuer, the system delivers the received digital identity document to the user/verifier.Type: GrantFiled: April 15, 2016Date of Patent: September 25, 2018Assignee: International Business Machines CorporationInventors: William F.
