Decentralized Identity for Automated Border Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing immigration process at border crossings, particularly at airports, is inefficient and resource-intensive due to the need for manual verification of identity documents, which becomes even slower during peak times and raises concerns about security and passenger satisfaction, especially with the limitations of biometric passports.
Innovation Solution
A method utilizing decentralized identity and digitally signed biometric data, validated by a trust anchor, is provided to the traveler before arrival, allowing for pre-authorization and efficient matching with a reduced set of authorized individuals using machine learning to predict arrival times and enhance biometric verification, enabling faster and more secure passage through automated border controls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual verification of identity documents is used, then security can be maintained through thorough checking, but processing time increases and productivity decreases
Solution Approach 1:
The system performs preliminary verification actions by pre-generating and storing authorized bearer lists with biometric data before the actual immigration process. This allows the system to quickly match arriving passengers against pre-processed data, maintaining security while dramatically reducing processing time at the border.
Solution Approach 2:
The system creates digital copies of identity document data and biometric information, storing them in authorized bearer lists. These copies enable rapid automated verification without requiring physical document inspection, thus maintaining security verification while improving processing speed.
2Productivity
If biometric passports with automated border controls are implemented, then processing speed improves, but capital investment and device complexity increase
Solution Approach 1:
The system extracts only the essential verification data (biometric information and authorization status) from complete identity documents and stores it in simplified authorized bearer lists. This extraction reduces the complexity of data processing while maintaining verification effectiveness, avoiding the need for complex biometric passport infrastructure.
Solution Approach 2:
Instead of having the system verify each passenger's complete identity documents in real-time, the invention inverts the approach by pre-verifying and storing authorization data, then simply matching arriving passengers against this pre-processed list. This reversal dramatically simplifies the real-time verification process.
3Reliability
If complete identity verification is performed for all passengers, then security is maintained, but queuing time increases and passenger satisfaction decreases
Solution Approach 1:
The system performs verification actions in advance by pre-processing passenger data and creating authorized bearer lists before arrival. This preliminary action allows rapid matching at the border, maintaining verification accuracy while eliminating long queues that cause passenger dissatisfaction.
Solution Approach 2:
The verification process is segmented into two phases: pre-verification (creating authorized bearer lists) and rapid matching (comparing arriving passengers against the list). This segmentation allows thorough verification to occur beforehand, while actual border processing becomes a quick matching operation.
4Productivity
If decentralized identity with pre-authorization is used, then processing efficiency improves, but system complexity and trust verification requirements increase
Solution Approach 1:
The system introduces an intermediary mechanism (authorized bearer lists with digital signatures) that mediates between the decentralized identity system and immigration verification. This intermediary simplifies the interaction by providing a trusted, pre-verified data structure that both parties can rely on, reducing overall system complexity despite the decentralized architecture.
Data Source
AI summary
A method and system for identity document verification issues a decentralised identifier for a passenger which is then used by a passport issuing authority to digitally sign passport data including enhanced biometric data including an image of the bearer. A copy of the signed data is provided to the bearer. Prior to travel the bearer submits APIS data and their decentralised identifier to the authorities at the arrival destination. This data is verified in advance and the bearer issued with authority to use a pre-authorised section at immigration. On arrival an image of the bearer is acquired and matched with records of pre-approved traveler. If a match is made, the bearer is permitted to pass through automatic border control gates. The matching process may use machine learning to reduce the set of pre-approved passengers used in the match based on predicted time of arrival at immigration.
