IoT-Enabled Cloud Storage Data Access Control Model Based on Blockchain Technology

Abstract

Cloud-based data access control security systems (CSDA) are the most versatile and elegant choice for SMEs and mid-sized enterprises. Storage, The idea of "the cloud" refers to the use of remote servers and data centers maintained by a third party, in this example, an internet service provider. There is no longer a need to invest in specialized data storage facilities due to the availability of on-demand data storage infrastructure with elastic storage capacity and variable storage prices. Authentication of Internet of Things devices is crucial for establishing that linked gadgets are what they claim to be. To reduce the likelihood of malicious behavior, access control regulates the access to the resources under the conditions. For cloud storage to function, at least one data server must be connected to the internet. Data supplied over the internet to a data server might be stored in "the cloud," where a copy of the data is kept. When necessary, the user may access this information through a web-based interface. The major issues with cloud computing are related to people's expectations of privacy and data security. Cryptography and other security methods may help keep personal information safe and secure. The data is separated into smaller bits by using a cloud storage service that relies on blockchain technology (BT). Then, it disperses this additional security over the network. Blockchain features, including hashing, private key encryption, and transaction ledgers, make this possible. CSDA-BT cloud storage is a new approach to archiving data and other digital artifacts in the cloud. Files may be accessed and viewed from any location with an internet connection. The cloud has several benefits, including easy accessibility, backups, and high availability. To stay competitive while becoming closer to their customers, cloud storage businesses must work on lowering pricing and making storage faster. Cheap data storage enables novel forms of expression.
