Data storage method and device

Abstract

The invention discloses a data storage method and device, and belongs to the technical field of data storage. The method comprises the following steps of: obtaining a plurality of frames of images in video data; slicing each frame of image in the plurality of frames of images to obtain slice data of each frame of image; carrying out redundancy processing on the slice data of each frame of image to obtain redundant data of each frame of image; and on the basis of a user identifier of a local terminal, sending the slice data and redundant data of each frame of image to other user terminals in a group, to which the user identifier belongs, so that the other user terminals in the group, to which the user identifier belongs, can store the received data. According to the data storage method and device disclosed by the invention, the data is sent to the other user terminals in the group, to which the user identifier belongs, so that the user terminals in the group can store the received data. The video data can be stored at the other user terminals in the group, so that the data loss caused by the fact that data is easily damaged since being stored locally can be avoided, and then the security of the data is ensured.

Description

technical field [0001] The invention relates to the technical field of data storage, in particular to a data storage method and device. Background technique [0002] With the rapid development of technology, more and more users use cameras. When using a camera, a user usually needs to store video data captured by the camera, such as storing video captured by a surveillance camera. Since the storage method of the video data affects subsequent acquisition of the video data, it is necessary to select an appropriate data storage method. [0003] When the related technology stores video data, the method adopted is: store the video data on a local storage medium. Wherein, the local storage medium may be a hard disk, a flash memory, and the like. For example, after a surveillance camera captures video data, the surveillance system can store the video data into the flash memory of the corresponding device. [0004] In the process of realizing the present invention, the inventors...
