Solution Overview
Problem
Existing digital video sharing methods do not allow for the conveyance of additional information or functionality beyond visual and audio content, limiting the ability to transfer digital currency or values within videos.
Innovation Solution
Embedding cryptographically obscured digital tokens within digital videos using encryption keys, allowing the tokens to be stored in metadata or video/audio data, enabling secure and transferable digital currency representations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If digital tokens are embedded only in video metadata, then the embedding process is simple, but the tokens can be stripped along with metadata
Solution Approach 1:
The patent embeds digital tokens within the video data structure by nesting them inside video frames or audio packets. The token data is hidden within the existing video container format, making it resilient to metadata stripping while maintaining secure cryptographic embedding. This nested structure ensures the token survives standard video processing operations.
Solution Approach 2:
The patent moves the token embedding from the metadata dimension to the actual video/audio data dimension. By embedding tokens within the temporal and spatial structure of video frames or audio samples, the system creates a new dimension of storage that is independent of traditional metadata structures, thereby preventing token loss during metadata stripping.
2Reliability
If digital tokens are embedded within video/audio data, then the tokens are more secure against stripping, but the embedding process becomes more complex
Solution Approach 1:
The patent divides the video data into discrete segments (frames or audio packets) and embeds token data within specific segments. This segmentation allows the embedding process to work with manageable units, reducing overall complexity while ensuring the token is distributed across multiple segments for enhanced security and resilience.
Solution Approach 2:
The patent uses cryptographic intermediaries (encryption keys and algorithms) to mediate between the token data and the video structure. This intermediary layer simplifies the embedding process by providing standardized cryptographic operations that can be applied systematically across video frames without requiring complex custom embedding logic.
3Adaptability or versatility
If additional information is conveyed through embedded tokens, then the video functionality is enhanced, but the video file size increases
Solution Approach 1:
The patent embeds token data locally within specific video frames or audio packets rather than uniformly across the entire video. This localized embedding minimizes the overall impact on file size while concentrating the additional functionality where it is most needed, allowing selective enhancement of video functionality without proportional increase in total data volume.
Solution Approach 2:
The patent embeds only the essential token information required for functionality within the video data, using partial embedding rather than comprehensive data insertion. This approach provides sufficient functionality enhancement while avoiding excessive file size increases by embedding only the minimum necessary token payload.

AI summary
Embedding of digital tokens within a digital video can occur cryptographically using a public key in some embodiments. The digital video may be altered in a variety of ways so that the video itself contains an integrated token that can represent various quantities. Audiovisual data can be altered to contain both a token and a perceptible user auditory or visual cue as to the presence of the encrypted digital token. A video with an embedded digital token may be sent to users on the Internet. A video recipient may be able to view the video and also take additional action or gain additional functionality from the digital token embedded in the video. Tokens can be embedded by altering video metadata so that the perceptible video content itself is not changed in some embodiments.
