Checksum Compute Module for JavaScript Authenticity Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Web browsers face challenges in verifying the authenticity and integrity of JavaScript code stored locally due to the inefficiency of JavaScript in computing checksums, particularly on devices with limited processing power, leading to slow verification times.
Innovation Solution
Implementing a checksum compute module written in a more efficient programming language, such as C or C++, separate from the online application code module, to quickly determine and verify checksums for the JavaScript code, utilizing parameters or data bits, and providing the checksum to the application for authenticity verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If JavaScript code is used to compute checksums in web browsers, then the verification can be performed within the browser environment, but the processing speed is slow especially on devices with limited processing power
Solution Approach 1:
The patent introduces a checksum compute module written in C or C++ as an intermediary component that bridges the JavaScript application code and the native processing capabilities of the browser. This separate module performs the computationally intensive checksum verification operations using efficient native code, while the JavaScript code module remains responsible for application logic. The intermediary module receives parameters from JavaScript, computes checksums efficiently, and returns results to the application, thus resolving the contradiction between maintaining browser-based verification and achieving fast processing speeds.
2Productivity
If a separate checksum compute module written in C or C++ is implemented, then verification speed improves significantly, but the device complexity increases
Solution Approach 1:
The patent divides the browser application into distinct segments: the JavaScript online application code module and a separate checksum compute module written in C/C++. This segmentation allows each module to be optimized for its specific function - JavaScript for application logic and native code for performance-critical checksum operations. The modules communicate through well-defined interfaces, reducing the complexity burden by creating clear boundaries and responsibilities rather than mixing concerns within a single codebase.
Solution Approach 2:
The checksum compute module acts as a specialized intermediary that handles only checksum computations, isolating the complexity of native code integration to a single, well-defined component. This mediator pattern reduces overall system complexity by concentrating the complex native-JavaScript interface in one place rather than scattering complexity throughout the entire application code.
