Digital Identity Document Renewal With Segmented Validity Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The current process for renewing digital identity documents is burdensome for issuing authorities and service providers due to the need for frequent renewals, which lack sufficient IT capabilities and are constrained by regulations, leading to inefficiencies and increased load on traditional systems.
Innovation Solution
A lightweight renewal mechanism that allows digital identity documents to be renewed by creating and sending up-to-date validity-related data items to the user's device, independent of the issuer, reducing the need for full document regeneration and delegating renewal tasks to service providers with minimal privacy risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If full data preparation and document regeneration is performed for each renewal, then the reliability of the digital identity document is maintained, but the load on issuing authorities' IT systems increases significantly
Solution Approach 1:
The patent segments the digital identity document into two parts: permanent data (personal information, document details) and validity-related data (expiration dates, renewal information). Only the validity-related data is renewed frequently while the permanent data remains stable, allowing efficient renewals without regenerating the entire document.
Solution Approach 2:
The patent performs preliminary action by pre-establishing the validity-related data items and their renewal policies during the initial document issuance. This allows the system to automatically manage renewals by simply updating the validity-related data without reprocessing the entire document creation workflow.
2Reliability
If frequent renewals are performed to maintain security, then the security of the digital identity document is enhanced, but the burden on issuing authorities increases
Solution Approach 1:
The patent divides the document into permanent data and validity-related data, allowing the system to renew only the validity-related data frequently for security maintenance while keeping the complex permanent data structure unchanged and stable.
Solution Approach 2:
The patent introduces validity-related data items as intermediaries that carry renewal information and expiration dates. These intermediaries simplify the renewal process by encapsulating all necessary renewal logic and validity information in separate, manageable data structures.
3Productivity
If service providers are delegated renewal tasks, then the issuing authorities can reduce their load, but the service providers face constraints from privacy regulations
Solution Approach 1:
The patent extracts only the necessary validity-related data (expiration dates, renewal information) from the full personal data set. This allows service providers to perform renewals using minimal data, reducing their exposure to privacy regulation constraints while maintaining sufficient functionality.
Solution Approach 2:
The patent applies partial action by having service providers process only the partial validity-related data rather than the complete personal data set. This limited scope reduces the regulatory burden on service providers while still achieving the renewal objective.
4Manufacturing precision
If the entire digital identity document is regenerated during renewal, then the document is fully updated, but the time required for renewal increases
Solution Approach 1:
The patent segments the document update process into updating permanent data (minimal changes) and validity-related data (frequent updates). This segmentation allows rapid renewal of validity information without the time-consuming regeneration of the entire document structure.
Solution Approach 2:
The patent performs preliminary action by pre-structuring the document with separate validity-related data items that are designed for efficient updates. This preliminary structuring enables rapid renewal operations without needing to regenerate the entire document hierarchy.

AI summary
Provided is a method for facilitating the renewing of a digital identity document. It includes receiving a request for renewing a digital identity document; checking whether said digital identity document can be renewed, if the check result is positive, creating an up-to-date validity-related data item to be associated with said digital identity document and to be inspected by a verifier when the validity of said digital identity document must be assessed; and sending said up-to-date validity-related data item to a device of a user of said digital identity document so that a validity-related data item previously associated with said digital identity document can be replaced by said up-to-date validity-related data item at the user's side.
