Problems solved by technology

With more and more video transmission lines, even a relatively powerful processor will have insufficient processing power
[0003] At present, unstructured data is transmitted in a compressed manner. Unstructured data such as audio and video compression rate is not high, and the bandwidth time is relatively long during the data transmission process. With more and more collection points, the efficiency of concurrent aggregation will decrease, which will inevitably lead to partial collection. The failure rate of point data upload increases, and the data cannot be aggregated in a timely, accurate and effective manner

Embodiment Construction

[0021] Explanation of terms used in the present invention includes the following parts:

[0022] Unstructured data fragmentation technology: Distributed coding technology is adopted to physically slice unstructured data first, and then fragmentize each file. Each piece of unstructured data uses a different encryption algorithm, and the same unstructured data The fragmented data can be encrypted using multiple encryption algorithms at the same time.

[0023] Data Aggregation: Combining data from different data sources.

[0024] MD5: Message Digest Algorithm MD5 (Chinese name is the fifth edition of Message Digest Algorithm) is a hash function widely used in the field of computer security to provide message integrity protection.

[0025] Hash: Hash, also directly transliterated as "hash", is to convert an input of any length (also called pre-mapping, pre-image) into a fixed-length output through a hash algorithm, and the output is the hash value . This conversion is a compres...

Abstract

The invention provides an unstructured data and fragmented data aggregation system. Message queue service, a memory library, a file type database and daemon process and various technologies are used, and the system can efficiently process and merge mass fragmented data of unstructured data (for example, audio and video data). A strict encryption and decoding strategy is used, and the system ensures safety and correctness of merging.

Description

technical field [0001] The invention relates to the field of computer data processing, in particular to a collection system for unstructured data and fragmented data. Background technique [0002] Safe City is the largest system with the most complex business. The scale of video access in the security field ranges from thousands to hundreds of thousands. The size of data is growing at an alarming rate. For a large amount of video data, distributed storage and centralized storage coexist in practical applications. Video retrieval personnel cannot work in a distributed manner and require centralized work, so the distributed video data must be aggregated. Integrate a variety of public security internal and social image information resources into the image resource library, and sort out, classify and store audio, video, and image information concerned by various departments and police types. At the same time, establish index summaries to facilitate evidence search and case corr...
