Abstract

The invention discloses a video sharing method and system in a cloud storage system based on source tracing information. A system client collects video source tracing information, and uploads a shared video and related video source tracing information. A server builds a source tracing map according to the video source tracing information uploaded by the client. A cloud storage system server receives a video downloading request, and then searches a start video of the requested video in the source tracing map. If the start video is found in the cloud storage system, a path with the lowest cost from the start video and the requested video is selected according to a BFS (breadth-first search) algorithm, and the requested video is generated again according to the path and is transmitted to the client. The cloud storage system takes the access heat value, the storage cost and the new generation cost of the video as the basis of video compression. The method makes the most of the cloud computing capability to reduce the space expenditure of video storage.

Description

technical field [0001] The invention belongs to the technical field of computer data storage, and more specifically relates to a video sharing method and system based on traceability information in a cloud storage system. Background technique [0002] In 2011, IDC released a report showing that the total amount of global data in 2011 was 1.8ZB. It is predicted that by 2020, the total amount will reach 35ZB. The era of "big data" has arrived. With the widespread use of video editing software as well as digital cameras and smartphones, and users can conveniently upload or download videos via the Internet, approximate video data in video sharing platforms has increased dramatically. Most existing video sharing platforms use cloud storage systems to store and manage videos, because cloud storage systems can provide different service management strategies based on systems or applications, and cloud storage systems support automatic increase and decrease of storage space according...
