Image Pickup Apparatus Blockchain Hash Verification

The patent applies preliminary action by calculating and registering hash values at predetermined time points during the live distribution process. The image pickup apparatus calculates hash values of distribution data at specific intervals (e.g., every N seconds) and transmits them to the management apparatus for blockchain registration before potential falsification can occur. This proactive approach ensures authenticity is established in advance for real-time content.

The patent introduces hash values as an intermediary element that bridges the gap between real-time data streaming and authenticity verification. Instead of directly verifying the entire video stream, the system uses hash values as intermediaries that represent and verify the integrity of the original distribution data at specific time points, enabling efficient authenticity guarantee without processing the entire real-time stream.

The patent applies segmentation by dividing the continuous live distribution data into discrete segments at predetermined time intervals. Instead of calculating one hash value for the entire video file, the system calculates hash values for specific time segments (e.g., 1-second intervals). This reduces the computational burden at each time point while maintaining authenticity verification for the entire live stream through cumulative hash verification.

The patent implements periodic action by calculating hash values at regular predetermined intervals during live distribution. The system computes hash values periodically (e.g., every N seconds) rather than continuously or for the entire file at once. This periodic approach balances processing time requirements with authenticity guarantee, ensuring verification without excessive computational overhead.
