Embodiment Construction

[0028] In order to make the purpose of the present invention: technical solutions and advantages clearer, the following examples are given to further describe the present invention in detail.

[0029] Introduce the storage structure of the BlueSky file system. The boot sector of the disk is located in sector 0 of the disk. The disk adopts the GPT partition type. The disk is divided into 8 partitions. The function of partition 1 is unknown; partition 2 records the monitoring operation log using SQLite database , Partition 3 is the backup partition of Partition 2; Partition 4 records the recording start time and end recording time of each stage of each channel, and Partition 5 is the backup partition of Partition 4; Partition 6 is a management partition, mainly used for management For the video in the data area, partition 7 is the backup partition of partition 6; partition 8 is the monitoring data area, which is used to store monitoring video.

Abstract

The invention discloses a method for extracting data of BlueSky file system monitoring equipment rapidly. The method includes the steps of S1, loading disk data; S2, detecting whether the disk data meet requirements or not; S3, analyzing disk structure; S4, analyzing normal data records; S5, analyzing abnormal data records; S6, classifying and extracting video data; S7, recombining fragmented data. The method has the advantages that normal video, deleted video and fragmented video of a BlueSky file system can be extracted completely and rapidly, and the fragmented data can be recombined, thereby helping in data recovery of enterprises and case detection of the public security organization.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a method for quickly extracting data from a BlueSky file system monitoring device. Background technique [0002] The vigorous development of the domestic economy has driven the development of many industries, and the security industry is one of the industries that benefit from the most obvious growth trend in the process of economic development. Especially with the continuous development of video surveillance technology today, professional surveillance equipment such as high-definition surveillance video and multi-angle video technology have been effectively promoted in various places in various industries. Video surveillance equipment has made a great contribution to the realization of a stable, harmonious and safe social environment. The video captured by the surveillance probe is particularly important, providing the most authentic and reliable video evidence for...
