Information Security Management of Sharing Economy Based on Blockchain Technology

Based on the unprecedented development of current information technology, under the prevalence of third-party payment, in order to increase the utilization rate of idle resources and meet the diversified economic needs of today's era, as an emerging economic model-the "sharing economy", combined with Internet big data, it has effectively realized the perfect connection between supply and demand, and it has quickly swept through all walks of life. However, while promoting economic development, the lack of regulatory measures and the imperfect credit system have severely restricted the further development of the sharing economy. Blockchain technology (BT), as a new distributed infrastructure and computing method, has always been the core technology of Bitcoin. Based on the development of generalized economic model and BT, this paper analyzes the shortcomings of generalized economic model and blockchain technology through information fusion big data and proposes a kind of information based on information fusion big data+public BT. The security management system adapts to the status quo of the sharing economy and uses the functions of information fusion big data+blockchain technology to solve the current information security risks faced by the sharing economy. The experimental results of this article show that the sharing economy information security management system based on information fusion big data+blockchain technology has good protection capabilities. The interception rate of external information reached 95%, and the interception rate of system information reached 93%. Better protection of privacy leaks is needed.
