Server Image Access Control via Face Masking and Payment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information exchange technologies face inefficiencies and increased processing costs due to the need for unnecessary extra information forms, such as blurred images, which can lead to congestion in network environments, as users often cannot determine whether to return additional information forms for decryption.
Innovation Solution
An information access control method involving a server that identifies faces in shared images, applies masks to select portions, and allows users to initiate decryption upon payment, ensuring only necessary information is exchanged, thereby reducing unnecessary interactions and processing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If blurred images are sent to all users for information exchange, then information privacy is protected, but processing costs increase and network congestion occurs
Solution Approach 1:
The patent applies different quality levels of images to different users based on their authorization status. Authorized users receive clear images while unauthorized users receive blurred images. This local differentiation allows privacy protection for unauthorized users while providing full access to authorized users without unnecessary processing costs.
Solution Approach 2:
The system dynamically adjusts image quality based on real-time authorization status. When a user becomes authorized (e.g., through payment or relationship verification), the system transitions from sending blurred images to clear images. This dynamic adaptation eliminates the need to send blurred images to all users permanently, reducing processing costs.
2Reliability
If blurred images are sent to all users, then information security is maintained, but network efficiency deteriorates
Solution Approach 1:
Different image quality versions are sent to different user groups based on authorization. Authorized users receive clear images directly, while unauthorized users receive blurred images. This local quality differentiation maintains security for unauthorized users while improving network efficiency by avoiding unnecessary blurred image processing for authorized users.
Solution Approach 2:
The system dynamically switches between sending blurred and clear images based on authorization status changes. When users become authorized, the system transitions to sending clear images, eliminating wasted network bandwidth on blurred image transmissions to authorized users while maintaining security protocols.
3Ease of operation
If extra information forms are exchanged for decryption, then access control is enforced, but processing costs and time increase
Solution Approach 1:
Authorization status is determined in advance before image transmission. The system checks whether users are authorized and sends appropriately formatted images (blurred or clear) from the beginning, eliminating the need for subsequent decryption processing and extra information form exchanges.
Solution Approach 2:
The patent extracts the authorization verification step and performs it before image transmission. By determining authorization status in advance, the system removes the need for time-consuming decryption processes and extra information form exchanges that would otherwise be required to enforce access control.

AI summary
Embodiments of the present disclosure provide an information access control method performed by a computer server, the method including: receiving an image sharing request from a first terminal, the image sharing request including a first image to be shared among a user group of a social networking application; identify one or more faces in the first image through face recognition; randomly selecting one of the faces in the first image; applying a mask to the first image except a predefined portion of the randomly-selected face; sending the partially masked first image to a second terminal; receiving an image viewing request from the second terminal in response to a user selection of the partially masked first image and a user-initiated resource transfer from the second user account to the first user account; and returning a version of the first image not being partially masked to the second terminal.
