    Abstract The Internet of Things (IoT) and cloud technologies have encouraged massive data storage at central repositories. Software-defined networks (SDN) support the processing of data and restrict the transmission of duplicate values. It is necessary to use a data de-duplication mechanism to reduce communication costs and storage overhead. Existing State of the art schemes suffer from computational overhead due to deterministic or random tree-based tags generation which further increases as the file size grows. This paper presents an efficient file-level de-duplication scheme (EFDS) where the cost of creating tags is reduced by employing a hash table with key-value pair for each… More >

    A Scalable Double-Chain Storage Module for Blockchain

    Hui Han1,2, Wunan Wan1,2,*, Jinquan Zhang1,2, Zhi Qin1,2, Xiaofang Qiu1,2, Shibin Zhang1,2, Jinyue Xia3

    CMC-Computers, Materials & Continua, Vol.73, No.2, pp. 2651-2662, 2022, DOI:10.32604/cmc.2022.028607

    Abstract With the growing maturity of blockchain technology, its peer-to-peer model and fully duplicated data storage pattern enable blockchain to act as a distributed ledger in untrustworthy environments. Blockchain storage has also become a research hotspot in industry, finance, and academia due to its security, and its unique data storage management model is gradually becoming a key technology to play its value in various fields’ applications. However, with the increasing amount of data written into the blockchain, the blockchain system faces many problems in its actual implementation of the application, such as high storage space occupation, low data flexibility and availability,… More >

    Data De-Duplication Process and Authentication Using ERCE with Poisson Filter in Cloud Data Storage

    B. Venkatesan1,*, S. Chitra2

    Intelligent Automation & Soft Computing, Vol.34, No.3, pp. 1603-1615, 2022, DOI:10.32604/iasc.2022.026049

    Abstract The cloud storage is essential environment for users to access high confidential data. Every single data is most valued by users. If we count, day by day information as well as, memory storage are increasing gradually. Cost of memory will increase when data increases with demand for storage. At present data duplication or redundant data storing in the cloud became hard for storage provider. Also, it makes security issue if repeated data from various users stored in the server. It makes data duplication, which is very efficient for intruders. Also, when same data stored in cloud, there will be a… More >
