Disclosed herein is a method for linking a blockchain using a hyper-chain and an apparatus therefor. According to the present invention, a correlation of a common block on at least two blockchains is identified by a predetermined method, and a hyper-block including an information of the correlated common block on the at least two blockchains is stored on a hyper-chain.

Method for linking block-chain using hyper-chain, and apparatus therefor

closed circuit television (CCTV) image data distribution processing apparatus includes a CCTV image data receiver configured to receive CCTV image data from a CCTV camera, an encryption processor configured to perform encryption-processing on the CCTV image data, a data splitter configured to split the CCTV image data into chunk data, an index processor configured to perform index-processing on the chunk data with an index generated through the encryption, and a controller configured to distribute and store the index-processed chunk data in a plurality of storage servers corresponding to corresponding indexes, respectively, or to decode chunk data to restore original CCTV image data when receiving the chunk data stored in the storage server.

CCTV video data distribution processing device and method thereof

A smart surveillance system includes a communicator configured to communicate with a closed circuit television (CCTV) camera and a cloud server, a background image extractor configured to analyze CCTV image data received from the CCTV camera and to extract a background image, an object image analyzer configured to distinguish an object image from the background image through big data analysis of a CCTV image, a region of interest (ROI) extractor configured to extract an ROI corresponding to the object image, and a controller configured to provide the background image and the ROI to the cloud server, to receive the background image and the ROI from the cloud server, to combine the background image and the ROI, and to generate a complete CCTV image, if necessary.
