Document Access Link Extension via User Behavior Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users cannot access documents provided through access links once the links become invalid, requiring document providers to reset the links, which is inconvenient for both providers and recipients.
Innovation Solution
A method and device that determine whether a user has identified an access link before it becomes invalid, allowing continued access to the document if the user has performed actions like clicking, saving, or sharing the link, thereby extending access even after the link's validity period has expired.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the access link validity is strictly enforced to ensure security and control, then document access control is improved, but user convenience deteriorates because users cannot access documents after the link becomes invalid
Solution Approach 1:
The system performs preliminary actions by detecting user identification behaviors (clicking, saving, sharing) before the access link becomes invalid. When such behaviors are detected, the system proactively extends access permissions, allowing users to continue accessing documents even after the original validity period expires, thus maintaining user convenience while preserving security through behavioral verification
Solution Approach 2:
The access control system transitions from a static validity period model to a dynamic model that adjusts access permissions based on user behavior. The system dynamically extends the access link validity when identification behaviors are detected, creating a flexible access control mechanism that adapts to actual user needs while maintaining security through behavioral verification
2Ease of operation
If the access link validity period is extended to improve user convenience, then ease of operation is improved, but document security and control deteriorate because users can access documents indefinitely
Solution Approach 1:
The system performs preliminary detection of user identification behaviors (clicking, saving, sharing) before the access link expires. Based on these detected behaviors, the system proactively extends access permissions, creating a conditional extension mechanism that balances user convenience with security by requiring specific user actions to qualify for extended access
Solution Approach 2:
The system changes the access control parameter from a fixed validity period to a dynamic validity period that extends based on user behavior parameters. When identification behaviors are detected, the system modifies the time parameter of access permission, allowing extended access while maintaining security through behavioral verification rather than indefinite access
3Reliability
If the access link is reset frequently to maintain security, then document access control is improved, but device complexity and operation time increase because the provider must continuously manage and reset links
Solution Approach 1:
The system implements self-service access control by automatically detecting user identification behaviors and extending access permissions without requiring manual intervention from the document provider. The automated behavior detection and permission extension mechanism eliminates the need for frequent manual link resets, reducing operational complexity while maintaining security through automatic behavioral verification

AI summary
Disclosed are a document providing method and apparatus. The method comprises: receiving an access request to a target document that is sent by a user; determining whether an access link used by the user is valid; if the access link is invalid, further determining whether the user identifies the access link before the access link is invalid; and if yes, providing the target document for the user. According to this application, by providing a document providing method and apparatus, when the access link is invalid, it is further determined whether the user identifies the access link before the access link is invalid, and if yes, the target document is provided for the user, so that a user that obtains the document provided by the access link when the access link is valid can obtain the document provided by the access link again after the access link is invalid, thereby providing convenience for the user to obtain the document.
