Abstract:
The software and hardware applications are clearly on the way of becoming an integral tool of business,
communication and popular culture in many parts of the world. People are interacting with the environment via the
Internet to perform physical activities remotely. These applications are hosted in the public or private servers under
the control of the server admin. The users’ online usage data can be stored in public or private cloud platforms, used
for processing and monitoring users’ online behaviour and emotional factors and shared with third parties to
facilitate making their business decisions. When users allow their data to be collected via software applications and
mobile devices, users need to have some level of trust and control over their data. But, software applications or
mobile devices connected to the cloud server using client–server architecture does not ensure the reliability, security
and integrity among their data. To get over these kinds of limitations, we propose a database management system
using blockchain technology that can be used by any software applications. The blockchain database connected to
the cloud server can be used to increase the trustfulness of the application. Blockchain has the capability to provide
decentralization, immutability and owner-controlled digital assets among software applications. Since users can save
their data in a shared transaction repository with tamper-resistant records, it enables related parties to access and
control users’ data without the need for a central control system.
