Prioritized Blacklist Management for Waste Container Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large-capacity garbage container access systems face inefficiencies due to high data processing requirements and memory needs when managing long lists of authorized or blocked identification codes, leading to increased memory usage, data transmission volumes, frequent updates, and prolonged access authorization times.
Innovation Solution
An electronic blocking list management system that prioritizes entries in the blacklist based on the last use of non-access-authorized keys, using a prioritization algorithm that considers features like frequency of use, geographical distribution, and outstanding invoices, to create a shorter yet effective blocking list, reducing memory and processing burdens while ensuring unauthorized access is minimized.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a long blacklist with all blocked identification codes is maintained to prevent unauthorized access, then security against unauthorized use is improved, but memory requirements and data processing time increase
Solution Approach 1:
The patent segments the monolithic blacklist into multiple prioritized groups based on risk assessment. High-priority blocked IDs (those with recent or frequent unauthorized access attempts) are placed in a small fast-check section, while lower-priority entries are in a larger secondary section. This segmentation allows the system to quickly reject unauthorized access attempts using only the critical high-priority subset, reducing average processing time while maintaining security.
Solution Approach 2:
The system performs preliminary risk assessment and prioritization of blocked identification codes before they are used for access control. By pre-calculating and ordering the blacklist based on factors like frequency of unauthorized attempts and recency of activity, the system prepares an optimized lookup structure in advance. This preliminary action ensures that during actual access authorization, the system only needs to search through the prioritized list, significantly reducing search time compared to an unsorted comprehensive blacklist.
2Measurement precision
If a comprehensive blacklist is updated frequently to reflect current blocked users, then authorization accuracy is improved, but data transmission volume and processing load increase
Solution Approach 1:
The patent extracts and transmits only the essential high-priority portion of the blacklist to access control points, rather than transmitting the entire comprehensive list. By identifying and separating the critical subset of blocked IDs that pose the greatest security risk, the system reduces data transmission volume significantly while maintaining authorization accuracy for the most relevant cases. Lower-priority entries can be handled locally or with less frequent updates.
Solution Approach 2:
The system changes the parameter of data representation by transmitting prioritized rankings and risk scores alongside or instead of complete blacklist data. This parameter transformation allows receiving systems to efficiently filter and process only the most relevant blocked IDs based on their local context and risk thresholds, reducing overall data transmission requirements while maintaining accurate authorization decisions.
3Reliability
If a long blacklist is stored in access systems to ensure complete blocking coverage, then security coverage is improved, but memory requirements increase
Solution Approach 1:
The patent segments the blacklist storage into multiple priority-based sections within the access system memory. Only the essential high-priority blocked IDs are stored in the primary fast-access memory, while lower-priority entries are either stored in secondary storage or handled through periodic remote updates. This segmentation maintains comprehensive security coverage by preserving all blocked IDs while optimizing memory usage by prioritizing storage of the most critical entries.
Solution Approach 2:
The system implements partial action by storing and actively managing only the necessary subset of the blacklist locally at access points. Rather than requiring complete local storage of all blocked IDs, the system maintains a prioritized subset that provides sufficient security coverage for the majority of cases, accepting that rare edge cases involving lower-priority blocked IDs can be handled through alternative verification methods or remote checks.

AI summary
The invention relates to an electronic blocklist management system and a method for authorization control for the use of a waste collection container (2.1, 2.2, 2.n), wherein the blocklist management system comprises a data management system (1) and a plurality of access systems (3.1, 3.2, 3.n) that can be activated by means of a plurality of keys (6, 6.1, 6.2, 6.n), each of which can be assigned to a user or a user group, for electronic authorization control for the use of an individual waste collection container (2.1, 2.2, 2.n) assigned to each individual access system (3.1, 3.2, 3.n), wherein both the data management system (1) and each of the access systems (3.1, 3.2, 3.n) have a communication interface (10.1, 10.2, 10.n) by means of which data is exchanged between the data management system (1) and each individual access system (3.1, 3.2, 3.n). 3.2, 3.n) are interchangeable.
