Unique Container ID and Credential Validation for Secure Prepaid Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for dispensing food and other items lack assurance that only authorized containers are used and that they are used within the intended time frame, leading to potential misuse and inefficiencies in transaction processing.
Innovation Solution
A system and method utilizing uniquely identified containers with a computer-based validation process that generates a credential ID, linking it to the container ID, and authorizes the dispensing of prepaid products only when both IDs match and conditions of sale are met, ensuring secure and efficient transactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a generic container is sold to a customer for self-service dispensing, then customer convenience is improved, but the system cannot insure that only the authorized container is used or that it is used within the intended time frame
Solution Approach 1:
The system segments the authorization control into two separate components: a container ID that identifies the physical container and a credential ID that verifies customer authorization. This segmentation allows the container to be universally accepted while maintaining strict authorization control through the credential verification process at each dispensing event.
Solution Approach 2:
The system introduces a central validation server as an intermediary between the dispensing kiosk and the customer. This intermediary validates the credential ID against the container ID and enforces the time-frame restrictions, enabling the kiosk to remain simple and customer-friendly while ensuring reliable authorization control through the server's validation logic.
2Device complexity
If existing dispensing schemes are used without unique identification, then device complexity is reduced, but the system cannot insure that the container is authorized or used within the intended time frame
Solution Approach 1:
The system uses digital copies of identification data (container ID and credential ID) rather than physical security features. The container ID is stored as data in the validation server's database, and the credential ID is verified as a digital copy. This allows complex authorization verification to be achieved through simple data comparison at the kiosk level, maintaining device simplicity while ensuring reliable authorization.
Solution Approach 2:
The system replaces any potential mechanical security features (such as physical locks or manual verification) with an electronic validation process. The kiosk simply reads the container ID and credential ID and compares them against stored data through the validation server, substituting mechanical complexity with electronic data processing that is both simple to implement and reliable in ensuring authorization.
3Reliability
If multiple separate transactions are required for each dispensing event, then authorization control is improved, but labor and equipment costs increase
Solution Approach 1:
The system performs the authorization validation action preliminarily at the time of the first dispensing event by linking the container ID to the credential ID in the validation server's database. This preliminary action establishes the authorization relationship once, allowing subsequent dispensing events to use the same linked identifiers without requiring repeated manual verification or separate transactions, thereby improving productivity while maintaining reliable authorization control.
Solution Approach 2:
The validation server provides feedback by automatically comparing the container ID and credential ID against stored data and returning an authorization decision. This feedback mechanism enables the kiosk to quickly verify authorization without requiring multiple separate transactions or manual intervention, improving transaction efficiency while maintaining strong authorization control through the automated validation process.
Data Source
AI summary
A system and method for providing a pre-paid product using a unique container. The system comprises a computer system comprising a storage medium readable by a processing circuit and stored instructions for execution by the processing circuit. The computer system includes a sales module that acquires an identifier for the unique container and generates a credential ID for a customer. The sales module also activates the unique container, and stores the identifier for the unique container and the corresponding credential ID in the storage medium. Also included is a dispensing module that receives a request from a remote dispensing device for validation of the unique container to receive the prepaid product, compares a received identifier and a received credential ID with the identifier and the credential ID stored in the storage medium, and authorizes the dispensing of the prepaid product if they match.
