Abstract:

Aiming at the massive data security problems, effective management method is necessary to be established in key vehicle supervision under Internet of things. In order to ensure the information security of key vehicle supervision platform, technologies for ensuring massive data security are studied. First of all, standardization system of supervision platform is established to contribute to security data exchange between heterogeneous networks. Then a vehicle information management mode based on Hadoop distributed parallel technology is proposed to ensure the data can be stored and processed efficiently. Then map-matching algorithm and technology of temporal GIS is applied to check authenticity of service data. In the end, a data support with the characteristics of safe, reliable and real can be supported by the key vehicle supervision platform with the realization of the technologies above.

Key words: key vehicle information management model, Internet of things, massive data, security guaranty mechanism, heterogeneous network
