There are multiple tangible reasons and benefits to using cloud storage services, but with its ambiguous nature, is it something we can completely trust with our information? Senior Professor Willy Susilo and his team are working in just this space. With a recently awarded ARC grant, they are keen to find solutions for securing cloud storage with protection against malicious senders.

“Just put it in the cloud” is a sentence most of us have heard at this point in our lives. Every time we get a new phone or device we are told that uploading our information “in the cloud’ is the safest and easiest option for storing and transferring our data. While the definition for the cloud can at times seem a little murky and confusing to the general population, it is now a way of life for those using digital technologies with it integrated into various facets of our day.

The cloud is a model of data storage in which digital data is stored in logical groups. The physical storage spans multiple servers (often across multiple geographical locations), and the physical environment is typically owned and managed by an external hosting company. These cloud storage providers are responsible for keeping the data available, accessible, and ensuring the physical environment of the servers is protected and operational. Individuals and organisations buy or lease storage capacity from the providers to store user, business, or application data.

Through this service provider, cloud computing is a system that serves as an internet-based information centre where customers can access all kind of files and software safely through several different devices, no matter where they are. Cloud storage services may be accessed through a co-located cloud computing service, a web service application programming interface (API) or by applications that utilize the API, such as cloud desktop storage, a cloud storage gateway or Web-based content management systems.

Simply put, cloud computing is the delivery of computing services – including servers, storage, databases, networking, software, analytics and intelligence – over the Internet (“the cloud”) to offer faster innovation, flexible resources and economies of scale.
