The Relationship between Big Data Survey and Technical Survey
It's all evidence collection. Big data investigation and technical investigation are both methods of applying advanced technical means to criminal investigation and evidence collection. Among them, big data investigation is mainly based on the analysis, mining and processing of a large number of data, and mining and extracting criminal clues through data association, patterns and trends. Technical investigation is mainly based on the application of communication, network, computer and other technologies, and obtains or restores the data evidence of the crime scene through technical means such as data collection, preprocessing, analysis and restoration. Big data investigation mainly analyzes large-scale data such as social big data, Internet data and Internet of Things data, with a view to discovering some new or specific criminal clues; Technical investigation is mainly based on communication, network, computer and other technical means to obtain or restore the data evidence of the crime scene. On the other hand, the data sources of big data investigation are more extensive and the types of data covered are richer, while technical investigation relies more on traditional investigation methods and on-site evidence collection.
