Application of Internet of Things Technology in Safe Centralized Storage of Big Data Information

Abstract

To solve the problem of low data processing rate in traditional medical information storage methods, a safe centralized storage method of medical big data information is proposed. The data set storage model is designed through the Internet of Things, and VeritasBackupExee is used as data recovery and backup software, and data recovery and backup are realized by the Internet of Things. Encrypted storage of ciphertext index vector is carried out by using the ciphertext storage algorithm, and the medical data center of Internet of Things middleware is constructed. By sharing storage devices with multiple hosts, highly reliable backup can be realized. The average response time of the method in this paper is different for medical big data services. The average response time for modifying service is 11ms, creating service is 12ms, and migrating service is 13.7 ms. To verify the data service response time of this method, it is necessary to verify the response performance of different methods. The results show that this method has higher data download and upload rates and faster data service response.
