The invention discloses a blockchain-based digital asset processing method and device. The method comprises the following steps: receiving private ciphertext for a digital asset circulated from a sending end to a receiving end through a blockchain, and a preset public key; and obtaining a sharing public key for sharing the private ciphertext based on the preset public key, so that when the private ciphertext and the sharing public key are broadcast in the blockchain, blockchain nodes on the blockchain can share the private ciphertext based on the sharing public key and reach a blind consensus on the shared private ciphertext, and after the consensus on the private ciphertext is reached, the private ciphertext can be decrypted by at least one of three parties, i.e., the sending end, the receiving end and a monitoring end, based on a preset private key to obtain plaintext of the digital asset. The method and device provided by the embodiment of the invention has the advantages that the privacy right of a user is protected; under the premise of privacy protection, the single general digital asset can be smoothly circulated within one blockchain or among multiple blockchains, and a total currency amount remains unchanged; and a monitoring party other than the transaction parties can monitor transaction information at any time.

A video surveillance system is disclosed which addresses the issue of privacy rights and scrambles regions of interest in a scene in a video scene to protect the privacy of human faces and objects captured by the system. The video surveillance system is configured to identify persons and or objects captured in a region of interest of a video scene by various techniques, such as detecting changes in a scene or by face detection. In accordance with an important aspect of the invention regions of interest are automatically scrambled, for example, by way of a private encryption key, while the balance of the video scene is left in tact and is thus recognizable. Such region of interest scrambling provides distinct advantages over known code block scrambling techniques. The entire video scenes are then compressed, by one or more compression standards, such as JPEG 2000. In accordance with one aspect of the invention, the degree of scrambling can be controlled.
