Privacy Masking for Video Monitoring Image Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video monitoring systems face high storage and transmission resource occupation due to the need to provide both original and masked images for privacy protection, leading to wastage of storage and network resources.
Innovation Solution
A method and apparatus for displaying images based on privacy masking, where the image capture terminal acquires and provides only the original image, and the player terminal determines whether to apply privacy masking based on received authentication information and masking area information, reducing the need to transmit both original and masked images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the image capture terminal provides both original image and masked image, then privacy protection is achieved, but storage and transmission resource occupation increases
Solution Approach 1:
The patent extracts the privacy masking function from the image capture terminal and relocates it to the player terminal. Only the original image is transmitted from the capture terminal, while the masking operation is performed locally at the player terminal based on received masking area information, thereby eliminating the need to transmit separate masked images
Solution Approach 2:
The player terminal is designed to perform multiple functions: receiving original images, storing masking area information, determining whether masking is needed based on authentication results, and applying masking when necessary. This multi-functional approach allows a single terminal to handle both privacy protection and image display without requiring separate masked image streams
2Loss of energy
If the image capture terminal transmits only original image, then network resources are saved, but the player terminal must perform additional processing to apply masking
Solution Approach 1:
The masking area information is prepared and stored in advance at the player terminal before the actual masking operation. When an original image is received, the terminal retrieves the pre-stored masking area information and applies masking based on this prepared data, which simplifies the real-time processing requirements
Solution Approach 2:
The patent introduces masking area information as an intermediary data structure that carries the necessary masking instructions. This intermediary element allows the player terminal to determine whether masking is needed and where to apply it, without requiring complex real-time analysis of the image content

AI summary
The present application discloses a method and an apparatus for displaying an image based on privacy masking, which belong to the field of video monitoring. The method includes: acquiring a to-be-masked original image provided by an image capture terminal and privacy masking area information of the original image; wherein, the privacy masking area information is obtained by identifying the original image or is obtained from the image capture terminal and indicates an area in the original image which is required to be masked; determining whether the original image is required to be privacy-masked based on whether privacy unmasking permission information is stored; if the original image is required to be privacy-masked, performing privacy-masking on the original image based on the privacy masking area information to obtain a masked image, and displaying the masked image. In this way, the image capture terminal is only required to provide an original image without providing the original image and the masked image, so the costs of both storage and transmission are low, saving the storage resources and network resources of the image capture terminal.
