Encrypted QR Code Resource Sharing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional network resource sharing mechanisms lack adequate security and privacy, and operational convenience, as they rely on direct URL sharing without encryption or access control.
Innovation Solution
A method and device that generate and publish encrypted two-dimensional barcodes for resource sharing, allowing users to control access through encryption passwords, enhancing security and privacy by encrypting the barcodes before sharing on Internet platforms and communication clients.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If direct URL sharing is used in conventional network resource sharing mechanism, then operational convenience is improved, but security and privacy are worsened
Solution Approach 1:
The patent introduces an encrypted two-dimensional barcode as an intermediary between the shared resource and the user. Instead of directly sharing URLs, the system generates encrypted barcodes that contain the resource address information. This intermediary mechanism maintains operational convenience (users can still easily share and access resources) while improving security (the actual URLs are protected within encrypted barcode structures).
Solution Approach 2:
The patent transforms the sharing mechanism by changing the parameter format from plain text URLs to encrypted two-dimensional barcode images. This parameter transformation allows the system to maintain the functionality of resource sharing while enhancing security through encryption. The barcode encoding and decryption process preserves ease of operation while protecting the underlying resource addresses.
2Reliability
If encryption is added to network resource sharing, then security is improved, but device complexity is worsened
Solution Approach 1:
The patent replaces complex manual security management with automated encryption and decryption systems. The user device automatically generates encrypted two-dimensional barcodes and handles decryption processes without requiring users to manually manage security protocols. This substitution of automated cryptographic operations for manual security management reduces the perceived complexity for users while maintaining high security standards.
Solution Approach 2:
The patent uses two-dimensional barcode copies as a representation of the actual resource URLs. Instead of directly exposing the original URL structure, the system creates encrypted barcode copies that contain the necessary access information. This copying mechanism allows the system to maintain security through encryption while keeping the user interface simple and familiar through the use of visual barcode scanning.

AI summary
Methods and devices for resource sharing are disclosed. Address information of a resource to be shared can be acquired by a user device in response to a sharing request. A two- dimensional barcode corresponding to the address information of the resource can be generated by the user device. The generated two-dimensional barcode can be published by the user device to one or more of an Internet platform and a specified Internet communication application client via a network. The user device can include a first acquisition module,a generating module, and a publishing module.
