Security cloud technology to fully expand cloud storage cloud computing competition

In the construction of Safe city, the 4G (fourth generation) concept was fired very hot, typical includes cloud technology, intelligent analysis, face recognition and other High-tech cutting-edge technology. In many construction projects, these applications will be used as part of it, it seems that does not catch some of these trends are outdated, but can really play a role, it is not necessarily, the key lies in the application of demand and technical characteristics can match.

Cloud Technology "acclimatized"

The nature of cloud technology can be understood as the management and application of computer cluster. In the IT industry has long been the application of mature, in recent years to security this new world, although the idea is good, but if the simple apply to come over, unavoidably also a bit "acclimatized", for the following two reasons.

First of all, compared with the public Internet, security system is a closed network, at present, the country's largest security system is the security-led establishment of the safety of the city, at that time, all over the country have become a faction, forming a large and small "information island", networking and interoperability of the great cause is not yet completed, want to realize the concept of "big cloud" is even more difficult.

Second, the security industry in the data component is mainly video, in recent years, with the development of business applications, image Data format (mainly from the traffic card mouth) slowly more up, there are a small number of structured data, and the traditional IT industry in the form of data formats and characteristics of different, security industry for its own characteristics, Designed a dedicated storage data structure and hardware features closely related to the read-write mechanism, and cloud technology in the IT industry for physical devices, such as CPU, memory, hard disk, such as virtualization and other highlights to the security here after it seems to be a little "lap tone."

Therefore, cloud technology in the security industry's application more is the use of its original ideas and technology to meet the actual technical needs, and it industry in the traditional "cloud" concept and the application of the way is not equal.

Storage is an important application point. With the construction of Ping An city, the promotion of high-definition, the extension of data preservation time, so that each system designers and managers must face the problem of storage system expansion, simple increase of storage equipment just add an independent system, each independent storage point performance, capacity is not balanced, for managers, management burden increases. The cloud storage is designed to meet the needs of managers, where the cloud storage is more like a "intimate" management system, for users to manage all forms of storage equipment, the advantages include:

1, flexible space management: Support linear expansion, after joining the node can realize automatic data migration, ensure the load balance of each storage node;

2, the rapid retrieval of massive data: Distributed data reading, improve the overall data throughput;

3, System Integration data security: Each data generally has more than 3 copies of the backup;

4, High compatibility: The original storage resources can and clouds storage of virtual resource pool.

In addition to cloud storage, cloud computing is also a feature of cloud technology, the current application of Ping An city is to the mass of structured data query and statistics, the current security industry, the most typical structural data is traffic card port data. With the large number of cards in recent years, in the early days of the monitoring of Zhejiang, a county-level county of the vehicle data can reach 1 million, a prefecture-level can reach 6 million, if the query one months of data, data volume close to 200 million, the amount of data is very large. Traditional database query technology has been unable to meet, so we must rely on cloud computing, its technical advantages mainly lies in:

1, distributed storage: Improve the reading speed of mass data;

2. Distributed computing: It can realize the balance of computing resources of each compute node and improve the overall efficiency through parallel computing;

3, Memory Optimization: The commonly used data stored in memory, speed reading efficiency;

4, column query: Each of the field properties are set up the corresponding index table, through the query of the index table to replace the original data entry field query, can greatly improve the query and statistical efficiency.

Intelligent analysis of wind and rain accompanying

Compared with cloud technology, the intelligent analysis represented by "behavior analysis" is "Old man" in security industry, the journey can be described as rich and tortuous: when the initial appearance, the industry is very hot, generally believe that the replacement of artificial watching the era of monitoring has come, and later in the actual project to meet the bottleneck of the effect, encountered doubts, Then to the late rational return, repositioning, according to different industries to create a special application.

At present, the intelligent analysis technology has been in the finance, the prison, even newly arisen civil profession, has formed the very good real-time application point, and obtains the recognition. But in the city security monitoring, intelligent analysis in real-time detection has been unable to find a good application, there are many reasons: first, the city security Monitoring image screen for the requirements of intelligent analysis is too complex, what the environment has (technical level of interference), technically difficult "a recruit to conquer the world"; second, from the application requirements , a city has tens of thousands of cameras, even technically able to accurately achieve "wandering, stay" and other behavioral analysis, but in the absence of alarm, the existing monitoring personnel what basis to do?

From the current industry situation, in the construction of Ping An city, the main application of intelligent analysis in the analysis of video recording, to meet the operational needs of criminal investigation. In recent years, with the development of urban monitoring, in addition to traffic management, urban monitoring the largest application group is the police. The method of video detection has become one of the four investigative methods of criminal investigation, and the current video depth application in the industry is mainly focused on the business needs of criminal investigation. The criminal investigation business is more concerned with video, and there is a great demand for the tools that can improve the efficiency of their video viewing.

1, based on the background modeling technology to the video background modeling, the separation of the activities of the target;

2, through the shape of the texture to make 2 judgments, can be roughly in the activities of the goal of the target person or vehicle;

3, in the condition (to the target trajectory of the pre-judgment, image clarity, etc.), can also be a trajectory screening and feature matching, further filtering useless targets;

4, the formation of a list of results, by artificial way to filter.

5, finally in the results of the form of expression, can also be divided into various forms, such as concentrated playback, video abstracts and so on.

Now, in some major industries, the intelligent products used in criminal investigation are divided into online, off-line two kinds, the tools on line is generally a part of the actual combat application platform, mainly to the public security of the video resources to do processing, in the grass-roots application of the main online tools, off-line tools mainly for social surface resources, It is mainly used in the crime scene or the surrounding office, and is usually used in the work of the major criminal cases.
