Picture Broadcasting Signature Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing internet browser technologies face challenges in securely managing picture broadcasting, leading to malicious requests that compromise user experience by allowing unauthorized users to broadcast unwanted pictures, which current IP and username checks fail to prevent effectively.
Innovation Solution
A method and system that generate a user signature based on picture information, which is validated before broadcasting, ensuring only valid requests are processed, thereby filtering out malicious requests and enhancing security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If IP address and username checks are used to screen malicious requests, then the system can identify some unauthorized users, but malicious requests can still pass through and compromise user experience
Solution Approach 1:
The system generates a signature for each broadcasting request in advance, incorporating picture information, user identification, and random numbers. This preliminary signature generation ensures that when a request arrives, its authenticity can be immediately verified without complex real-time analysis, effectively blocking malicious requests before they compromise user experience
Solution Approach 2:
A signature verification mechanism is introduced as an intermediary layer between the broadcasting request and the picture transmission process. The signature acts as a mediator that validates the request's authenticity based on multiple parameters (picture hash, user ID, random number), preventing unauthorized users from injecting malicious content while maintaining smooth operation for legitimate users
2Ease of operation
If the system processes all broadcasting requests without verification, then user experience remains smooth, but malicious requests can be executed and harm the system
Solution Approach 1:
The system performs preliminary signature generation and verification before processing broadcasting requests. By pre-generating signatures containing picture hash values, user identifiers, and random numbers, and verifying them before execution, the system maintains smooth processing for legitimate requests while automatically filtering out malicious ones that lack valid signatures
Solution Approach 2:
The signature verification mechanism provides immediate feedback on the authenticity of broadcasting requests. Each request is checked against the expected signature derived from picture information, user identification, and random numbers. This feedback loop allows the system to accept valid requests smoothly while rejecting malicious ones, maintaining both operational efficiency and security
3Device complexity
If traditional IP and username verification methods are used, then the verification process is simple, but it fails to effectively prevent malicious broadcasting requests
Solution Approach 1:
The verification process transitions from checking simple parameters (IP address, username) to verifying a composite signature that incorporates multiple parameters including picture hash values, user identification, and random numbers. This parameter expansion maintains relatively simple verification logic while dramatically improving the effectiveness of malicious request filtering through multi-factor validation
Data Source
AI summary
A method and system for broadcasting pictures across multiple user terminals are provided. The method includes generating a user signature based on information associated with the picture, and receiving a request to broadcast the picture, the request including the user signature. The method further includes broadcasting the picture if the user signature is valid. The method and system may improve a user's online experience by eliminating unauthorized broadcasts from unauthorized users.
