Augmented Reality Image Origin Verification via Time Location Metadata
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods lack a robust and easy way to determine whether an augmented reality view is an original image captured by the user or a transmitted image, and whether an augmented reality model has been shared, which is crucial for content providers to manage annotations and track distribution effectively.
Innovation Solution
A method that involves capturing and storing data including time and location of mobile equipment usage, allowing users to share images or models with annotations, and using this information to determine if an image is original or transmitted by analyzing the time and location data stored on a server or locally, with optional use of additional parameters like embedded watermarks for higher reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If augmented reality annotations are added to images for enhanced information display, then the value and functionality of the content is improved, but the complexity of tracking whether the image is original or transmitted increases
Solution Approach 1:
The system performs preliminary actions by storing time and location data at the moment of image capture before sharing occurs. This pre-stored data enables later verification of image origin without requiring complex real-time tracking mechanisms during transmission or display.
Solution Approach 2:
Time and location data serve as intermediary elements that mediate between the original image capture and subsequent sharing/verification processes. These intermediaries provide objective criteria for determining image origin without requiring direct complex verification of each image transmission.
2Measurement precision
If time and location data are stored for each image capture to enable origin tracking, then the ability to differentiate original and transmitted images is improved, but the data storage requirements and system overhead increase
Solution Approach 1:
The system extracts only the essential elements needed for verification - time and location data - from the much larger image data. By taking out only these critical metadata elements for storage and verification purposes, the system achieves accurate origin detection without storing the complete image data, thereby reducing storage requirements.
3Loss of information
If the system tracks all image transmissions and annotations to provide detailed reporting, then the information availability for content providers is improved, but the processing time and computational resources increase
Solution Approach 1:
Time and location data are stored preliminarily at the moment of image capture, creating a ready-to-use verification record. When verification is needed later, the system can quickly compare the stored data with current data without requiring complex real-time processing, thus reducing processing time while maintaining comprehensive information tracking.
Data Source
AI summary
An originating user captures an original image with mobile equipment. The image is displayed on the originating user's mobile equipment with first annotations. First data information (R1) including the time and the location of the mobile equipment together with information that the first annotations has been displayed is sent to a server. The originating user transmits the image to a second equipment of at least one second user. The image is displayed on the second equipment. Second annotations are displayed to said second user in combination with said image. Second data information (R2) including the time and the location of equipment of the second user together with information that the second annotations has been displayed is sent to the server. The server determines from the location and/or time whether said image is an original image captured by the originating user, or a transmitted image displayed to a second user.
