Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Consumers face challenges in verifying the authenticity of digital media, particularly in social media platforms, where faked or tampered content is difficult to detect, leading to devaluation of content creators' brands and revenue loss.
Innovation Solution
A computer system with a database that stores verification information for digital media, allowing for the computation and comparison of hash codes and watermarks to authenticate content, providing feedback on authenticity and confidence levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If digital media is distributed widely across social media platforms, then the reach and potential impact of the content increases, but the risk of faking, tampering, and unauthorized copying increases
Solution Approach 1:
The system embeds verification data (watermarks, hash codes, metadata) into the digital media content during the creation or distribution phase, before the content reaches consumers. This preliminary embedding of authentication information enables later verification of authenticity without requiring changes to the distribution model itself.
Solution Approach 2:
The patent introduces an intermediary verification system that acts as a mediator between content creators and consumers. This system includes verification servers, database systems, and client applications that facilitate authentication by comparing embedded verification data against stored reference data, thereby enabling consumers to verify authenticity without direct access to the original content.
2Ease of operation
If consumers have no verification tools, then the ease of consuming digital media is maintained, but the ability to detect faked or tampered content is lost
Solution Approach 1:
The verification system is designed to be self-service oriented, where the consumer's device automatically performs verification checks by extracting embedded verification data and comparing it against reference data from verification servers. This automation eliminates the need for consumers to manually analyze content authenticity while still providing them with verification capabilities.
Solution Approach 2:
The system employs visual indicators (such as verification badges, icons, or color-coded markers) that change or appear based on the authenticity verification result. These visual cues provide immediate, intuitive feedback to consumers about content authenticity without requiring complex analysis, maintaining ease of operation while enabling detection of faked content.
3Reliability
If verification data is embedded in digital media, then the ability to verify authenticity is improved, but the complexity of the media file increases
Solution Approach 1:
The verification data is embedded within the existing digital media file structure using nested containers or metadata fields. For example, verification information is stored within standardized metadata structures (such as EXIF, XMP, or custom metadata fields) that are already part of common media formats. This nesting approach adds verification capability while maintaining compatibility with existing file formats and minimizing structural complexity.
Solution Approach 2:
The patent employs universal verification mechanisms that work across multiple media types (video, audio, images) and distribution platforms. The verification data structure and embedding method are designed to be format-agnostic and platform-independent, allowing a single verification system to handle diverse content types without requiring separate complex verification structures for each format.
4Measurement precision
If hash codes are computed for each editable unit of essence data, then the precision of verification is improved, but the computational resources and time required increase
Solution Approach 1:
The verification system divides the digital media content into editable units or segments (such as video clips, audio tracks, or metadata fields) and computes hash codes for each segment separately. This segmentation allows for efficient verification by only hashing changed portions rather than the entire file, reducing computational overhead while maintaining verification precision for each editable unit.
Solution Approach 2:
The system implements incremental verification that computes hash codes only for editable units that have changed or been modified, rather than re-hashing the entire media file. This partial action approach maintains high verification precision for modified portions while significantly reducing the time and computational resources required compared to full-file verification.
Data Source
AI summary
Tools and techniques are provided to detect faked, or tampered, or unauthorized digital media, such as video, audio, still images, and multimedia clips, and provide and display measures of confidence and validity. A computer system that supports distribution of digital media includes a database that stores information about distributed digital media that enables verification of such digital media. A computer system having access to that database can receive distributed digital media and compute verification data from that digital media. The computed verification data can be compared to the stored information in the database, to determine whether there is any digital media for which the verification data matched the stored information. If there is no match, the computer system can provide feedback that the received digital media cannot be verified. In the event of a match, the computer system can provide feedback that the received digital media has been verified.
