An Area-Context-Based Credibility Detection for Big Data in IoT

Abstract EN

In order to improve the credibility of big data analysis platform’s results in IoT, it is necessary to improve the quality of IoT data.

Many detection methods have been proposed to filter out incredible data, but there are certain deficiencies that performance is not high, detection is not comprehensive, and process is not credible.

So this paper proposes an area-context-based credibility detection method for IoT data, which can effectively detect point anomalies, behavioral anomalies, and contextual anomalies.

The performance of the context determination and the data credibility detection of the device satisfying the area characteristics is superior to the similar algorithms.

As the experiments show, the proposed method can reach a high level of performance with more than 97% in metrics, which can effectively improve the quality of IoT data.
