Browser Extension Session Detection via Inline Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing user authentication methods in web interactions often result in errors and resource wastage when scripts interact with web pages requiring authenticated sessions without checking for active sessions, leading to poor user experience and inefficient resource utilization.
Innovation Solution
A method involving a browser extension that creates an inline frame element to detect and determine the presence of an authenticated user session by requesting a secondary web page, modifying responses to allow rendering within the frame, and performing actions only when a session is active, thereby reducing errors and resource consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If scripts interact with web pages requiring authenticated sessions without checking for active sessions, then script execution can proceed without session verification, but errors and resource wastage occur
Solution Approach 1:
The patent applies preliminary action by checking for authenticated user sessions before executing scripts that require such sessions. The system proactively verifies session validity and prevents script execution when no active session exists, thereby avoiding errors and resource wastage while maintaining operational simplicity for users.
2Loss of energy
If scripts execute without checking for authenticated sessions, then resource consumption is high due to unnecessary executions, but implementing checks increases system complexity
Solution Approach 1:
The patent implements self-service by enabling the client device to autonomously detect the presence of authenticated user sessions and make execution decisions locally. This self-detection mechanism eliminates the need for complex server-side validation logic while preventing unnecessary script executions, thereby conserving network and device resources without significantly increasing system complexity.
3Measurement precision
If the inline frame element requests the second web page to detect session status, then accurate session detection is achieved, but additional network requests increase resource consumption
Solution Approach 1:
The patent applies partial action by using an inline frame element to request only a specific second web page for session detection purposes, rather than performing comprehensive authentication checks. This targeted approach achieves accurate session status detection while minimizing network resource consumption by limiting the scope of the detection request to what is strictly necessary.
Data Source
AI summary
In some implementations, a device may detect loading of a first web page associated with a domain, and may create an inline frame element that references a second web page associated with the domain. The second web page may require an authenticated user session to access particular content of the second web page. The device may insert the inline frame element into code for the first web page, and may transmit a request for the second web page based on inserting the inline frame element into the code for the first web page. The device may receive a response to the request for the second web page, and may determine whether there is an authenticated user session for the domain based on the response. The device may selectively perform an action based on determining whether there is an authenticated user session for the domain.
