Cloud storage is a service package in which data is stored, managed, backed up remotely and made available to users over a network and internet services. There are three main cloud-based storage architecture models: public, private and hybrid.
Body Area Networks (BANs)

Cloud storage is a service package in which data is stored, managed, backed up remotely, and made available to users over a network and internet services. Cloud storage is based on a virtualized infrastructure with accessible interfaces. Cloud-based data is stored in servers located in data centers managed by a cloud provider. A file and its associated metadata are stored in the server by using an object storage protocol. The server assigns an identification number (ID) to each stored file. When a file needs to be retrieved, the user presents the ID to the system and the content is assembled with all its metadata, authentication, and security. The most common uses of cloud services are cloud backup, disaster recovery, and archiving infrequently accessed data. Cloud storage providers are responsible for keeping the data available and accessible, and the physical environment protected and running. People and organizations buy or lease storage capacity from the providers to store and archive data files. Cloud storage services can be accessed via cloud computers and web services that use application programming interfaces (API) such as cloud desktop storage and cloud storage gateways.

Cloud storage is one of the typical services of cloud computing, which provides cloud users with an efficient way to save storage space, back data up online, and access data from any place and at any time via the Internet. However, this service brings some problems for both cloud users and Cloud Service Providers (CSPs). For data users, uploading data to the cloud makes them lose the direct control of their data. Especially when the data is related to their personal and sensitive information, data privacy leakages could happen. With the increasing concern about security and data privacy, data users prefer to upload their data to the cloud in an encrypted form. Moreover, different cloud users may have different preferences for the management of data based on the sensitivity of their data. It is obvious that the access control of popular data, like music or movies, is not as strict as that of sensitive data. Considering the risk of privacy leakage in the cloud, some cloud users prefer to control the access to data on their own. Some cloud users entrust a third party to take over the access control of their data when they are not convenient to do such a task or when they cannot be always online. Consequently, flexible data access control becomes critical for cloud storage service concerning different data security requirements and user demands. From the perspective of CSPs, repeatedly storing the same data by the same user or different users causes serious waste of cloud storage resources, especially in a big data scenario. Even if the storage capability of CSPs is large, they still need a lot of energy to manage those data. Therefore, it is urgent for the CSP to adopt some efficient resource management schemes, for example, deduplication, which is very useful for saving storage consumption and can finally benefit cloud users.
Self-Determination and Perceived Information Control in Cloud Storage Service

Cloud storage is a major cloud computing service that allows users to save their data on dedicated online storage systems instead of user-owned local systems.1 By migrating computing and data storage to cloud-based facilities, it offers significant financial benefits as well as mobility, flexibility, and scalability for users.1,2 But at the same time, users may raise concerns about the information privacy and security due to the duplication, dissemination, and deletion of data stored on the cloud.3,4 Unlike local storage, cloud storage operates in a multi-tenant environment where resources are shared, especially for the public cloud. Normally, users are unaware whether their data are being accessed or distributed by service providers or other third-parties. Thus, they lack the ability to fully protect their personal information from unauthorized or improper collection, access, and use. The threat of accidental or deliberate dissemination and use/reuse of personal information for unauthorized purposes is a critical impediment to the use of cloud storage service.5 Raising users’ confidence in cloud storage service and enhancing their perceptions of information control have become an essential task for the flourish of the service.
Keeping the user in the cloud: a cognitive social capital antecedent to use continuance and trust-commitment in personal cloud storage services
Published in Behaviour & Information Technology, 2019
Public cloud services have emerged as a strong challenger to traditional on-premises IT services (Gartner Research 2017a). Expenditure on public cloud services is growing at nearly seven times that of overall IT and is expected to reach $277 billion in 2021 (IDC 2018). The fastest growing cloud component is Infrastructure-as-a-Service (IaaS), partly due to the increased popularity of personal cloud storage services (Gartner Research 2017b). The ability to store and access personal files remotely in the cloud has led to a proliferation of cloud storage providers, of which Dropbox, Apple iCloud, Microsoft OneDrive, and Google Drive are popular examples (Arpaci 2016). Uptake for these services has been substantial: it is expected that, by 2020, 2.3 billion residential internet users will be using personal cloud storage services, transacting some 48 exabytes of data traffic per year (Cisco 2016).

This smart hospital bed has some easy use for the patient as the sleeping position of the patient and the sitting position of the bed. A hospital bed management system is a method that provides real-time status of all available beds and beds that are occupied to prepare for the most effective use of beds. It saves time for workers and management by counting and recording the availability of beds. In this process, the smart stretcher sensor and the IoT devices for tracking patient health are monitored by the IoT and the cloud-based system. Cloud storage can be used to store and process various types of sensor data, such as environmental, health and wellness, industrial, transportation, energy, and agricultural data. This data is collected from sensors and can be transmitted to the cloud for applications such as monitoring, analysis, and prediction. Cloud storage offers benefits such as efficient data management, scalability, and accessibility, making it an ideal solution for large-scale sensor deployments. Data storage is reflected in retrieving the data by removing noisy and unwanted data. Data cleaning is the process of identifying and eliminating the data, filling in missing numbers, removing noise from the data, identifying and removing outliers, and smoothing noisy data. Noisy data is any data that has been received, stored, or modified in such a way that it cannot be read or utilised by the program that produced it. Noisy data both unnecessarily increases storage space needs and can negatively impact the outcomes of any data mining analysis. This bed makes the rolling of the patient. If someone pushes or pulls, it can travel anywhere. This bed contains the place for placing the oxygen cylinder. This oxygen cylinder helps the patient with the respiratory system.
