    Long-Term Preservation of Electronic Record Based on Digital Continuity in Smart Cities

    Yongjun Ren1,2, Kui Zhu1,2, Yuqiu Gao3, Jinyue Xia4,*, Shi Zhou1,2, Ruiguo Hu1,2, Xiujuan Feng5

    CMC-Computers, Materials & Continua, Vol.66, No.3, pp. 3271-3287, 2021, DOI:10.32604/cmc.2021.011153

    Abstract Under the co-promotion of the wave of urbanization and the rise of data science, smart cities have become the new concept and new practice of urban development. Smart cities are the combination of information technology represented by the Internet of Things, cloud computing, mobile networks and big data, and urbanization. How to effectively achieve the long-term preservation of massive, heterogeneous, and multi-source digital electronic records in smart cities is a key issue that must be solved. Digital continuity can ensure the accessibility, integrity and availability of information. The quality management of electronic record, like the quality management of product, will… More >

    Digital Continuity Guarantee Approach of Electronic Record Based on Data Quality Theory

    Yongjun Ren1, 2, Jian Qi1, Yaping Cheng2, Jin Wang3, *, Osama Alfarraj4

    CMC-Computers, Materials & Continua, Vol.63, No.3, pp. 1471-1483, 2020, DOI:10.32604/cmc.2020.06745

    Abstract Since the British National Archive put forward the concept of the digital continuity in 2007, several developed countries have worked out their digital continuity action plan. However, the technologies of the digital continuity guarantee are still lacked. At first, this paper analyzes the requirements of digital continuity guarantee for electronic record based on data quality theory, then points out the necessity of data quality guarantee for electronic record. Moreover, we convert the digital continuity guarantee of electronic record to ensure the consistency, completeness and timeliness of electronic record, and construct the first technology framework of the digital continuity guarantee for… More >

    Digital Continuity Guarantee Method of Urban Construction Archives Based on Risk Management

    Ran Ou1,2, Fei Chen1,2, Yongjun Ren1,2,*, Yepeng Liu1,2, Qirun Wang3

    Journal on Big Data, Vol.1, No.2, pp. 71-77, 2019, DOI:10.32604/jbd.2019.06057

    Abstract With the broad application of information technology in urban infrastructure, urban construction has entered the stage of a smart city, forming many electronic records in urban construction. These electronic records play a vital role in the maintenance of urban infrastructure. However, electronic records often change in the process of urban construction. How to preserve the electronic records of urban construction became a significant challenge. In response to this problem, this paper proposes the use of risk-based management techniques to ensure the digital continuity, authenticity, integrity, and availability of electronic records More >
