A cloud-oriented large data integrity detection protocol Zhang Zhou Wenzin Shi Yunhua The advent of cloud computing has put forward a new direction for the development of computer, but many of the security problems have limited the development of cloud computing, in which the integrity detection of cloud storage is the most prominent. Due to the characteristics of large data, existing protocols on data integrity detection are not suitable for large data detection. Through the improvement of Juels protocol, this paper proposes a new data integrity detection protocol which is more suitable for large data storage, and improves the original protocol can only be limited ...

Research and application of large data storage technology based on NoSQL database Sun Zhunting The amount of data collected and processed in the actual project is very large, which presents a great challenge to the traditional database technology. Aiming at the disadvantage of traditional relational database with slow storage speed and high hardware requirement, a large data processing method based on NoSQL database is proposed, which breaks the relational model of traditional database, and the data is stored in a free way, but not dependent on fixed table structure. This method mainly combines empirical mode decomposition and NoSQL database technology, and is applied to deformation monitoring of large structural parts.
