Web Application Data Transmission via Zero-Width Characters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development environment for Web applications is limited, preventing direct information transmission between Web applications and other system applications, resulting in increased delays due to reliance on servers for information exchange.
Innovation Solution
An information transmission method that enables target applications to obtain information directly from Web applications through system APIs, modifying description information to include transmitted data and using zero-width characters for covert transmission, allowing direct reading of target information without server mediation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If information transmission between Web applications and other applications is carried out through a server, then information transmission can be achieved, but transmission delay increases
Solution Approach 1:
The patent uses zero-width characters as an intermediary mechanism to enable direct information transmission between Web applications and other applications. By embedding target information within zero-width characters in the webpage description information, the system achieves direct communication without server mediation, thus reducing transmission delay while maintaining reliability
Solution Approach 2:
The patent creates a copy of the target information and embeds it within the webpage description information using zero-width characters. This copied information can be directly accessed by target applications through system APIs, eliminating the need for server-based transmission and reducing delay
2Reliability
If Web applications are restricted in the Sandbox environment, then system security is maintained, but direct information transmission to other applications is prevented
Solution Approach 1:
The patent uses zero-width characters as an intermediary that allows Web applications to transmit information directly to other applications without breaking the Sandbox security model. The zero-width characters serve as a covert channel that operates within the permitted API boundaries while enabling direct communication
Solution Approach 2:
The patent changes the parameter of description information by embedding target information within zero-width characters. This parameter change allows the information to be transmitted directly through system APIs without requiring special permissions or breaking security constraints
