Geographic Location-Based Document Encryption and Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing document confidentiality methods in collaborative office environments are inconvenient and insecure due to the need to transmit passwords along with documents, which can lead to password loss and security risks.
Innovation Solution
Implementing geographic location-based encryption and decryption, where a target password is generated based on the location of the second electronic device storing the document, allowing operations only if the first electronic device's location matches the authorized region.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an operation password is used to protect the document, then document confidentiality is improved, but the convenience of document operation deteriorates due to the need to transmit the password along with the document
Solution Approach 1:
The patent extracts the password transmission requirement from the document sharing process. Instead of transmitting the password along with the document, the system separates these two actions. The document is encrypted with a password on the server side, but the password itself is not transmitted to clients. Access control is achieved through location-based authorization rather than password sharing, thereby maintaining confidentiality while improving operational convenience.
Solution Approach 2:
The patent introduces a location-based authorization mechanism as an intermediary between the document and the user. Instead of directly using passwords for access control, the system uses geographic location information as an intermediate verification factor. The server verifies whether the user's current location matches the authorized location range before allowing document access, thus eliminating the need for password transmission while maintaining security.
2Reliability
If an operation password is used to protect the document, then document confidentiality is improved, but security deteriorates due to the risk of password loss and insecure transmission
Solution Approach 1:
The patent extracts the password from the transmission process entirely. The document is encrypted using a password on the server side, but the password itself is never transmitted to clients. The encryption key remains securely stored on the server, and access is controlled through location-based authorization. This eliminates the security vulnerability of password transmission while maintaining document confidentiality.
Solution Approach 2:
The system performs automatic location-based access control without requiring users to manually manage passwords. The server automatically verifies the user's geographic location against the authorized location range and grants or denies access accordingly. This self-service mechanism eliminates the need for users to transmit, store, or manage passwords, thereby removing the security risks associated with password handling.
3Reliability
If geographic location based encryption is implemented, then security and convenience are improved, but device complexity increases due to location detection and verification mechanisms
Solution Approach 1:
The patent uses geographic location information as an intermediary for access control verification. Instead of implementing complex encryption algorithms on client devices, the system verifies the user's location through GPS or other location services and compares it with the authorized location range stored on the server. This approach maintains security while avoiding the need for complex client-side encryption mechanisms.
Solution Approach 2:
The patent replaces traditional mechanical password verification mechanisms with location-based access control. Instead of requiring users to input and verify passwords through complex authentication protocols, the system automatically verifies the user's geographic location using device location services. This substitution simplifies the access control process while maintaining security, as location verification is automatically performed by the device's built-in location services.

AI summary
A document processing method and apparatus are disclosed in embodiments of the present application. The method includes: obtaining a target geographic location where the first electronic device is currently located, when a predetermined operation for a document is detected; determining whether the target geographic location matches a target password that is used to encrypt the document in advance; and if so, allowing the predetermined operation to be performed on the document; and if not, preventing the predetermined operation from being performed on the document. The apparatus includes an obtaining module, a determining module, and a decision module. In the embodiment of the present application, the document is encrypted and decrypted by using a target password generated based on a geographic location, which ensures the security of password transmission, and improves the security of the use of the document and the convenience of authorization and decryption.
