Abstract

There are issues such as dishonest checking organizations and unreliable data storage in a deduplication scheme based on data popularity. This paper proposed a data popularity deduplication model for decentralized storage. To address the dishonesty of the checking agency, the model executed duplication checking and popularity checking of data by using smart contracts as the checking organization, which combined the non-tamper-ability of blockchain with the non-repudiation of smart contracts. It guaranteed the authenticity of the test results. To address the problem of unreliable data storage, it proposed a file chain storage structure. This structure satisfied the requirement of data popularity deduplication. Meanwhile, this structure established the logical relationship between the fragments which were distributed in different storage nodes to achieve physical/logical uploads by adding auxiliary information. The file chain storage structure provided the basis for popularity data in decentralized network storage. Besides, it added backup identifiers to the data block information, and divided the storage network into two virtual storage spaces with the help of the backup identifiers. Also, two virtual storage spaces were oriented for data detection and storage. It satisfied the user's backup needs. Security analysis and performance analysis show that the scheme is feasible, guarantees the authenticity of the test results, and improves the reliability of data storage.
