I. Introduction
With the development of digital technology, the increase in storage capacity, the development of communication technology, and the growth of computing power, there is a trend to demand “more practical, more accurate, and more information.” As a result, countless amounts of digital data are being naturally generated in many fields around the world. This trend will continue in the future, and the amount of data is expected to continue to increase infinitely. In addition, banking and shopping at marketplaces, which previously had to be done physically, have already been converted to internet banking and online shopping platforms and are now deeply utilized in our daily lives. Digital transformation, which is being actively promoted by the government and is expected to change in the near future, includes incorporating the use of currently partially established digital platforms into various aspects of daily life.
