Evaluation Study on Privacy Policies of Express Companies Based on Cloud Model

In the era of the Internet of things (IoT), smart logistics is quietly rising, but user privacy security has become an important factor hindering its development. Because privacy policy plays a positive role in protecting user privacy and improving corporate reputation, it has become an important part of smart logistics and the focus of express companies. In this paper, through the construction of the privacy policy evaluation index system of express companies, aiming at qualitative indicators that are difficult to evaluate, we introduce the cloud model evaluation method that can combine the qualitative and quantitative together, and comprehensively evaluate the privacy policy of five express companies in China from four indicators: general situation, user informed consent, information security control and personal rights protection. The results show that: Overall, the privacy policies of the five express companies have not reached the "good" level, and there is a certain gap between the privacy policies of different express companies. From the comparison of indicators, the five express companies generally score relatively good; However, the overall score of information security control index is relatively poor, and the other two indexes are quite different. Cloud model evaluation method has strong applicability for the evaluation of express company privacy policy, which provides a reference for improving the privacy policy formulation and improving the privacy protection level of China's express delivery industry in the era of IoT.
