Authorized Notification Routing with PHI-Filtered Message Listening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems face difficulties in providing notifications to authorized users while maintaining the protection of sensitive information, especially when multiple users are involved, as seen in record management systems where users desire updates on record adjustments.
Innovation Solution
A notification service that authenticates and authorizes secondary users to receive updates, monitors messaging flows, and uses bus listeners to identify relevant messages, ensuring compliance with regulations by separating and processing protected health information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If notifications are provided to multiple authorized users about record adjustments, then information sharing and collaboration are improved, but the risk of exposing sensitive protected health information increases
Solution Approach 1:
The notification service extracts and removes protected health information (PHI) from messages before delivering notifications to authorized users. The system identifies PHI elements in the original message and selectively excludes them from the notification content, allowing information sharing about record adjustments while protecting sensitive patient data.
Solution Approach 2:
The notification service acts as an intermediary between the messaging system and authorized users. It receives messages containing PHI, processes them by removing sensitive information, and delivers cleaned notifications to users. This intermediary layer enables information sharing while enforcing privacy protections.
2Reliability
If authorization verification is implemented for secondary users, then security and compliance are improved, but system complexity and processing time increase
Solution Approach 1:
The notification service performs authorization verification in advance before delivering notifications to secondary users. When a user subscribes to receive notifications about another user's records, the system verifies the authorization relationship beforehand, storing the authorized recipient information for efficient future notification delivery without repeated verification overhead.
Solution Approach 2:
The notification service automatically manages authorization verification and compliance checking without requiring manual intervention. The system self-verifies authorization tokens, checks compliance rules, and manages the complexity of security protocols internally, presenting a simplified interface to users while maintaining robust security.
3Object-affected harmful factors
If protected health information is removed from notifications, then privacy protection and regulatory compliance are improved, but the usefulness and completeness of notification content deteriorates
Solution Approach 1:
The notification service applies selective information filtering by removing only protected health information while preserving other relevant notification content. Instead of removing all detailed information, the system identifies specific PHI elements (such as patient identifiers, sensitive medical data) and removes only those portions, maintaining local quality by keeping non-sensitive information intact for notification completeness.
Solution Approach 2:
The notification service segments the message content into protected health information and non-sensitive information. It separates PHI elements from other notification data, removes only the segmented PHI portions, and delivers the remaining non-sensitive segments to users. This segmentation approach maintains notification usefulness while enforcing privacy protections.
Data Source
AI summary
A method and system for initiating message listening and routing message content to authorized user devices is disclosed. For a second user device to receive notifications regarding records of a first user, the second user device provides information identifying the first user to a notification service. The notification service verifies the identifying information. The notification service initiates one or more listeners to listen for messages flowing over a messaging bus that are relating to the first user. Once a message is identified, at least a portion of the message is used to generate a notification that may be sent to the second user device.
