Summary of U.S. Patent No. 12,254,103
Title: Security mechanism for namespaces used in electronic identification on mobile devices
Assignee: Thales DIS France SAS
Inventors: Mourad Faher, Carole Bayle
Filing Date: September 25, 2020
Issue Date: March 18, 2025
Abstract:
A system, mobile device, and method for managing security policies for data items stored in an electronic identification (eID) wallet on the mobile device. Security policies are associated with each of a plurality of supported namespaces on a mobile device and a verifier terminal operates to select a namespace to access a data item stored on the mobile device based on the security policies associated with the plurality of supported namespaces on the mobile device.
Plain-Language Overview of Independent Claims
This patent has three independent claims: Claim 1, Claim 11, and Claim 16.
Claim 1: This claim describes a method for managing security for electronic ID wallets on a mobile device. The core idea is that the system first links different security rules to various data categories (called "namespaces") on the device. Then, a separate device, called a "reader," communicates with the mobile device and chooses which data category to access based on these security rules.
Claim 11: This claim focuses on the mobile device itself. It specifies a device with a processor and memory that stores an eID wallet application. The application is designed to receive a list of selected data categories ("namespaces") from a reader. In response, the device sends back the specific security rules for each of those selected categories using a predefined data format (a "bytestring template").
Claim 16: This claim outlines a comprehensive, back-and-forth method for securely accessing data.
- A mobile device has security policies for its various data "namespaces."
- The device sends these policies to a reader.
- The reader selects one or more namespaces it's interested in and sends this list back to the mobile device.
- The mobile device then sends the specific security policies for just the selected namespaces.
- The reader checks if it can comply with the security rules for any of the selected namespaces.
- If it can, it picks one, proves to the mobile device that it meets the security requirements, and is then granted access to the data. If it cannot, access is denied.
