Abstract: A system may receive a tracking update created by a tracking device. The tracking update comprising geographic location information indicative of a current geographic location of the tracking device. The system may identify, in a blockchain, a smart contract including executable logic configured to calculate a tracking metric. The system may determine, using the executable logic, the tracking metric in response to receipt of the tracking update. The system may append a datablock to the blockchain. The datablock may include the tracking metric and the geographic location information. The system may synchronize the blockchain with a plurality of blockchains stored in blockchain databases.

Abstract: A video information recorder receives video information including multiple scenes, and associates an automatic start marker with at least one of the scenes in response to receiving user-provided begin scene information. According to one embodiment, during playback the video information recorder stops recording in response to receiving the user provided begin scene information and resumes recording in response to receiving the user provided end scene information. According to an alternative embodiment, during playback the video information recorder skips, erases or overwrites the video information between the start and stop markers. The video information recorder also associates an automatic stop marker with at least one of the scenes without user intervention in response to receiving user-provided end scene information.
