With the ever-growing use of digital technology, especially the use of big data technologies and machine learning, questions related to the proper use of data collected from social networks led to the introduction of data transparency. Hence, the authors open the discussion on crucial problems of data use "in many application areas … dealing with personally identifiable information." There are many cases where personal data theft has led to privacy breaches and the possibility of identity theft. This fact asks for appropriate solutions, and the authors successfully aim their study at data transparency, knowing that it is not easy to achieve. Many cybersecurity techniques have been implemented, but our almost fully networked business, social, and personal lives need a robust and decentralized approach. This study recognizes blockchain's potential for a variety of applications, as it can "provide real-time data visibility and transparency while keeping private information secure" [1].
