Locker specific access authorization information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current compartment systems for delivery and storage face challenges in securely managing access authorization information, including reliance on central systems for communication, vulnerability to power failures, and potential misuse due to long validity periods and theft of access devices.
Innovation Solution
A method for generating and providing access authorization information that allows secure access to compartments within a compartment system, using a device or system that includes at least two devices for generating and outputting this information, with features such as cryptographic verification and limited validity periods to enhance security and reduce complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If access authorization information is stored centrally in a central system, then the same access authorization information can be used for multiple compartments, but communication with the central system is required which increases device complexity and power consumption
Solution Approach 1:
The patent extracts the compartment identifier from the access authorization information and makes it directly visible in the access authorization check. Instead of requiring a central system to interpret and map access authorization information to compartments, the compartment identifier is embedded in the access authorization data structure itself, allowing the compartment system to independently determine which compartment to grant access to.
Solution Approach 2:
The patent creates a copy of the compartment identifier within the access authorization information structure. Rather than relying on a central system to maintain and query the relationship between access authorization and compartments, the compartment identifier is copied into the access authorization data, enabling local verification without central system communication.
2Device complexity
If access authorization information is stored locally in the compartment system, then communication with central system is avoided, but the assignment information is lost in case of power failure or system disruption
Solution Approach 1:
The patent enables the compartment system to independently verify access authorization information without requiring communication with a central system. The compartment identifier embedded in the access authorization data allows the compartment system to self-determine which compartment to grant access to, making the system self-sufficient and eliminating the need for external communication infrastructure.
3Ease of operation
If access authorization information has long validity period, then convenience for multiple access processes is improved, but risk of misuse after theft of access device increases
Solution Approach 1:
The patent dynamically adjusts the validity period of access authorization information based on the specific access scenario. Rather than using a fixed long validity period for all access authorizations, the system can set different validity durations appropriate to each compartment access event, balancing convenience with security by limiting the window for potential misuse.

AI summary
Among other things, a method is disclosed comprising generating and/or outputting access authorization information, the provision of which to a compartment system is a necessary condition for granting access to a compartment of a plurality of compartments of the compartment system by the compartment system. In particular, when the access authorization information is generated, it is already clear which of the compartments of the compartment system the compartment is specifically concerned with, and the access authorization information is generated at least using information identifying the compartment in such a way that the compartment can be determined by the compartment system using the access authorization information is. The compartment system can be stateless with regard to the determination of the compartment using the access authorization information. The access authorization information and the subject system can be designed in such a way that the subject system does not have to receive any further information from external units apart from the access authorization information in order to carry out a check as to whether access to the compartment of the subject system can be granted on the basis of the access authorization information and/or that the subject system to Carrying out this check exclusively from that device from which the specialist system receives the access authorization information. Further related methods as well as corresponding computer programs and devices are also disclosed.
