Audio-Video Contract Records With IPFS and Blockchain Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing contract systems face challenges in proving the authenticity of oral contracts, are prone to forgery and falsification, and require time and costs for documentation, especially when made on the spot.
Innovation Solution
A system and method utilizing Interplanetary File System (IPFS) and blockchain technologies, along with audio and video encryption, electronic signatures, and digital signatures to create secure and transparent audio and video contracts, incorporating metadata and watermarks to prevent forgery and falsification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If oral contracts are made on the spot using recoders or mobile phones, then convenience and speed are improved, but reliability and authenticity are worsened due to forgery and falsification risks
Solution Approach 1:
The patent introduces a server as an intermediary that receives audio/video contract data, processes it, and stores it securely. The server acts as a trusted mediator between contracting parties, converting oral contracts into verified digital records with metadata, thereby maintaining the convenience of oral contracts while eliminating forgery risks through centralized verification and storage
Solution Approach 2:
The patent creates digital copies of oral contracts by converting audio/video recordings into structured data with metadata (timestamp, location, participant information). These digital copies are stored on a server and can be verified without the original physical recording, preventing forgery while preserving the convenience of oral agreement formation
2Reliability
If written contracts are used with electronic signatures, then reliability is improved, but time consumption and procedural complexity are worsened
Solution Approach 1:
The patent performs preliminary actions by automatically generating contract documents, adding metadata, and preparing digital records before the actual signing process. The server pre-processes audio/video data, extracts relevant information, and creates structured contract formats in advance, so that when parties need to sign, the documentation is already prepared and ready for quick electronic signature
Solution Approach 2:
The patent replaces mechanical documentation processes (manual typing, paper handling, physical signing) with automated digital processes. Audio/video recordings are automatically transcribed and structured into contract formats by the server, eliminating the need for manual documentation work while maintaining legal validity through electronic signatures
3Loss of information
If audio/video recordings are used to prove oral contracts, then completeness of contract content is improved, but ease of operation is worsened due to verification difficulties
Solution Approach 1:
The patent segments the contract verification process into distinct components: audio recording, video recording, metadata extraction, and structured data storage. Each element is separately captured and organized by the server, making verification simpler because each component can be independently checked against its corresponding metadata (timestamp, location, participant ID) rather than analyzing entire raw recordings

AI summary
A server for providing a contract support service communicates with a plurality of contractor terminals, the Interplanetary File System (IPFS) and a blockchain network, and manages member information for the plurality of contractor terminals. The contract support service provision server acquires audio/video contents including audio/video files in which contract-related audio/video data are stored and metadata for audio/video, in response to a request for contract support from one contractor terminal of the plurality of contractor terminals, generates contract document information corresponding to the contract-related audio/video data, generates a provisional contract content including the generated contract document information and audio/video contents, generates first link information adapted to provide access to the generated provisional contract content and second link information adapted to provide connection with a web page to receive electronic signatures of the plurality of contractor terminals as an input, and transmits the generated first link information and second link information to the plurality of contractor terminals included in the request for contract support. In addition, when a plurality of electronic signatures are input for each contracting party from the plurality of contractor terminals that have confirmed the provisional contract content, contract support service provision server generates audio/video watermarks for the contract content including the provisional contract content and the plurality of electronic signatures, adds the generated audio/video watermarks to the provisional contract content to generate a contract content for storage, encrypts the contract content for storage using an encryption key, and stores the encrypted contract content for storage in a distributed manner using the Interplanetary File System (IPFS) and the blockchain network.
