Internet of Things (IoT), as a typical representation of cyberization, enables the interconnection of physical things and the Internet, which provides intelligent and advanced services for industrial production and human lives. However, it also brings new challenges to IoT applications due to heterogeneity, complexity and dynamic nature of IoT. Especially, it is difficult to determine the sources of specified data, which is vulnerable to inserted attacks raised by different parties during data transmission and processing. In order to solve these issues, data provenance is introduced, which records data origins and the history of data generation and processing, thus possible to track the sources and reasons of any problems. Though some related researches have been proposed, the literature still lacks a comprehensive survey on data provenance in IoT. In this paper, we first propose a number of design requirements of data provenance in IoT by analyzing the features of IoT data and applications. Then, we provide a deep-insight review on existing schemes of IoT data provenance and employ the requirements to discuss their pros and cons. Finally, we summarize a number of open issues to direct future research. [ABSTRACT FROM AUTHOR]

Beneath the “Chinese success story,” social stratification, class polarization, and cultural displacement have increased dramatically. Can Confucian values contribute to dissolving the downsides of modernization in contemporary Chinese society? This paper investigates the current revival of Confucianism as a form of critique and a means of reconstructing of the Chinese socio-culture. Its data are user-generated videos. By means of a thematic audiovisual narrative analysis, the study is based on the material of 20 hours of Youku Paike videos uploaded between 2007 and 2013. The results are: (1) About one third of the user-generated videos can be interpreted as Confucian thematic narratives with a slightly increasing trend in portrayals of values of Confucian origin. (2) Under the circumstances of China’s present modernization and cyberization, Confucianism may be contributing to the formation of a new online socio-culture advocating social action and humanistic values.
