The Boston Marathon bombing on April 15 killed three people and injured many others, and the FBI collected about 10 terabytes of data near the scene of the crime after the Boston Marathon bombing. Although reports that the FBI and the Boston Police Department have "locked up and arrested suspects" through big data have been condemned by the FBI and the Boston Police Department, the use of big data to lock up suspects will become easier and more efficient in the future when big data analytics are perfected, social media norms and information-sharing mechanisms are sound, and the source and quality of the data are reliable.
Using big data can also prevent and fight crime. The University of Michigan has published a report online stating that researchers are using "supercomputers as well as large amounts of data" to help police locate those most vulnerable to lawbreakers, using large amounts of data to create a map of hotspots in high-crime areas of Boston. When looking at crime rates in one neighborhood, they also take into account factors in neighboring neighborhoods. As they add more and more data to the study, the researchers believe they will be able to draw more accurate conclusions about how additional variables affect crime rates and support police in targeting crime-prone spots and apprehending fugitives in a more targeted way.
Big data development and application can also help improve disaster relief systems.
When the 7-21 Beijing rainstorm occurred, the number of people calling for help was so high that rescue calls were overwhelmed, and stranded people were unable to get help from officials, so they turned to microblogging platforms. A microblog containing three elements of character, time and location can quickly understand the rescue needs, open the microblog additional coordinates data can be realized map positioning, for timely disaster relief to provide convenience. Ya'an earthquake, in addition to microblogging again highlights the advantages of new media communication, WeChat group and the major Internet companies launched the search platform also provides multi-channel support for disaster relief. However, the data of major websites are not interoperable, and the low accuracy and inefficiency of the data has become the biggest drawback. To maximize the value of data, it must be online, open, ****enabled, interconnected and relevant. This shows that the openness and *** enjoyment of data is a necessary and yet to be solved thing.
The analysis and mining of big data can realize the comparison of portraits, fingerprints, etc., as well as the data fusion processing of chokepoints. Mining the information behind the data is the established task of the public security organs, through what way to easily and conveniently complete this activity becomes particularly important. In talking about Jinan Public Security Bureau's partner Wave Zhang Qiang said, Wave Yunhai big data all-in-one machine is to cope with the information society, the core of the big data era of technical equipment, it marks the domestic free brand in big data processing has reached the international leading level, can imagine that with the construction of the safe city continue to deepen and promote the big data all-in-one machine such a data processing platform will also play a key role.
Based on the data resource system of the public **** safety data resource management platform, the urban operation of the public **** safety related data collection, integration, window processing, processing, construction of the indicator system, sorting out the urban operation of the physical characteristics of the city, the use of mobile terminals and other Internet of Things devices for mobile management, for the city to provide services such as operation and safety monitoring, comprehensive analysis, early warning prediction, auxiliary decision-making, etc., to give full play to the potential value of the data, in order to improve the safety of the city. Give full play to the potential value of data in order to improve the level of urban public **** safety management.
At present, various government departments have already established public **** safety information systems, but the overall level of intelligence has yet to be improved, and the value of data dispersed in various departments has not been brought into full play. The construction of the public **** security indicator system, the construction of public **** security data resource management platform, quantitative planning security management work, is to improve the government's security management capacity, the implementation of the national "12th Five-Year Plan" outline of the inevitable trend and an important initiative.
