Game Image Watermarking for Embedded Gameplay Traceability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for embedding electronic watermarks in game images fail to provide insight into the type of game processing performed, as they do not effectively convey information about the game processing through the watermark.
Innovation Solution
An information processing system that generates an electronically watermarked game image by embedding information on game processing, such as operation inputs and identifiers, using electronic watermarks, allowing the system to determine the type of game processing performed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If electronic watermark is embedded in game image using conventional techniques, then the watermark can be incorporated in the snapshot, but information on what kind of game processing has been performed cannot be known
Solution Approach 1:
The watermark information is segmented into specific game processing data elements such as operation inputs, collision information, and score data. This segmentation allows the system to embed only relevant game processing information rather than attempting to capture all possible data, thereby reducing the complexity of the embedding system while preserving essential game processing details.
Solution Approach 2:
The patent introduces an intermediary processing layer that captures game processing information from the game system and transforms it into watermark-compatible data formats. This intermediary component bridges the gap between the game processing system and the watermark embedding system, enabling information transfer without requiring direct integration between these complex systems.
2Loss of information
If information on operation input from player is embedded in watermark, then the operation input that has lead to the game image can be known, but the data amount of watermark information increases
Solution Approach 1:
The system extracts only the essential elements of operation input information that are necessary to understand the game processing, rather than embedding complete raw input data. This extraction process removes redundant information while preserving the core gameplay actions, thereby maintaining information utility while reducing watermark data volume.
Solution Approach 2:
The patent transforms operation input information into compressed parameter representations suitable for watermark embedding. By changing the parameter format from detailed raw input data to condensed game processing descriptors, the system maintains the ability to retrieve meaningful operation information while significantly reducing the data amount required in the watermark.

AI summary
An information processing system includes one or more processors and one or more memories storing instructions that when executed, cause the information processing system to perform operations including accepting an operation input from a player, performing game processing corresponding to the accepted operation input, and generating, for a game image based on the game processing, an electronically watermarked game image in which information on the game processing corresponding at least to the operation input is embedded by electronic watermark.
