Selective Message Access via Link Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing message delivery systems lack secure authentication mechanisms, allowing unintended devices to access messages intended for specific receivers, thereby compromising message security and wasting resources by transmitting messages to all devices associated with a shared identifier.
Innovation Solution
Implementing a message delivery device that selectively permits access to messages by authenticating the receiver device using authentication information and verification methods, such as digital certificates or biometric data, and generating links only for intended recipients, rather than transmitting the entire message.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If messages are transmitted to all devices associated with a shared identifier, then message delivery coverage is improved, but message security deteriorates and resources are wasted
Solution Approach 1:
The patent segments the message transmission process into two distinct phases: first transmitting a link to the message rather than the full message content, and then requiring authentication for actual message access. This segmentation allows the message to be delivered to multiple devices (maintaining productivity) while securing the actual content behind authentication barriers (improving reliability).
Solution Approach 2:
The patent introduces an intermediary authentication mechanism between the message link and the actual message content. The authentication server acts as a mediator that verifies device identity before permitting message access, thus enabling secure selective delivery without compromising delivery coverage.
2Productivity
If messages are transmitted to all devices associated with a shared identifier, then message delivery coverage is improved, but resource consumption worsens
Solution Approach 1:
The patent extracts the message content from the transmission process and replaces it with a lightweight link. Only the link (not the full message) is transmitted to multiple devices, significantly reducing network bandwidth consumption and computing resources required for message handling while maintaining delivery coverage.
Solution Approach 2:
The patent applies partial action by transmitting only the essential message metadata and link information to multiple devices, rather than transmitting the complete message content. This partial transmission achieves delivery coverage while minimizing resource consumption, with full message access restricted to authenticated devices only.
3Reliability
If authentication mechanisms are implemented, then message security is improved, but device complexity worsens
Solution Approach 1:
The patent introduces an intermediary authentication server that handles the complex authentication logic externally. The receiver device itself remains relatively simple, delegating authentication complexity to a dedicated server that manages credentials and verification, thus improving security without significantly increasing device complexity.
4Reliability
If selective authentication is implemented, then message security is improved, but ease of operation worsens
Solution Approach 1:
The patent implements preliminary authentication before message access, where devices are authenticated in advance when receiving the message link. This preliminary action establishes security credentials beforehand, allowing authenticated users to access messages conveniently without repeated authentication barriers, thus balancing security with ease of operation.
Data Source
AI summary
A device may receive an indication to generate a link associated with accessing a message. The message may be intended for a shared device identifier of a receiver device identified by a receiver device identifier, where the shared device identifier is shared by multiple receiver devices. The device may generate the link using information associated with the message. The device may provide the link to the receiver device after generating the link. The device may receive a request, from a requesting device, to access the message, the request including a device identifier associated with the requesting device. The device may selectively permit or prevent access to the message, by the requesting device, based on the receiver device identifier and the device identifier associated with the requesting device.
