Multimedia Object Processing for User Access Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current messaging systems do not provide users with information on who actually accessed multimedia content sent, beyond confirmation that the message was viewed on the recipient's device.
Innovation Solution
A method that captures a visual or audio representation of the vicinity when a multimedia object is opened on the recipient's device, extracts information on users present, and sends this information back to the sender, using existing sensors like cameras and microphones, or external sensors connected via a network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a visual or audio representation of the vicinity is captured when opening a multimedia object, then the information about who accessed the content is improved, but the device complexity increases
Solution Approach 1:
The patent reuses existing sensors (camera, microphone) already present in mobile devices for their primary functions, but also leverages them for the additional function of capturing vicinity representations to identify users. This multi-functionality approach avoids adding dedicated hardware while still achieving user identification.
Solution Approach 2:
The system uses the recipient's own device resources (sensors, processing capability) to capture and analyze the vicinity representation. The device serves itself by utilizing its existing infrastructure rather than requiring external specialized equipment, thereby minimizing additional complexity.
2Measurement precision
If sensors like camera or microphone are used to capture vicinity representation, then the measurement precision of user presence is improved, but the use of energy increases
Solution Approach 1:
The sensors are activated only at specific moments when a multimedia object is opened, rather than continuously. This periodic activation significantly reduces energy consumption while still capturing the necessary information about user presence at the relevant time.
Solution Approach 2:
The system triggers sensor activation in advance of the actual content viewing by detecting the opening action of the multimedia object. This preliminary triggering ensures that the sensors are active only when needed, optimizing the balance between measurement precision and energy usage.

AI summary
The invention proposes a method for processing a multimedia object sent by a sender device and received (F10) by a recipient device, this method being intended to be implemented by the recipient device and comprising: - a step (F40) of obtaining at least one visual or audio representation of a neighbourhood of the recipient device acquired during an opening of the multimedia object on the recipient device; - a step (F50) of extracting said representation of at least one item of information about users who may have had access to a content of the multimedia object during its opening on the recipient device; and - a step (F60) of dispatching said at least one item of information to the sender device.
