Application: Image pickup apparatus capable of guaranteeing authenticity of content distributed in real time while photographing, content management apparatus, control method for image pickup apparatus, control method for content management apparatus, and storage medium (Patent ID: US20240205033A1)
The patent filed by Canon Inc. describes an image pickup apparatus that ensures the authenticity of real-time distributed content by transmitting distribution data, generating hash values at intervals, and sending this information to a content management apparatus for registration in a blockchain. The apparatus can generate hash values based on time elapsed, frames passed, distance moved, or subject changes during transmission. The content management apparatus receives distribution data, hash values, and timing information, generates identification numbers, and registers hash values in a blockchain for authenticity verification.
Additionally, the patent outlines control methods for both the image pickup apparatus and the content management apparatus, involving steps for transmitting distribution data, generating hash values, and registering information in a blockchain. The methods ensure the integrity and authenticity of live-distributed video content by comparing hash values and timing information stored in the blockchain. The patent also includes non-transitory computer-readable storage mediums storing programs for executing the control methods described for both the image pickup apparatus and the content management apparatus, emphasizing the importance of blockchain technology in verifying the authenticity of real-time distributed content.
