Initially, humans could not draw as they perceived. It was only after the discovery of perspective that they could accurately draw what they saw. Perspective was first applied to performance stages in Greece during the 5th century BC, and it was not until the 15th century that the Italian architect Brunelleschi succeeded in expressing a three-dimensional perspective on a two-dimensional plane. In the long history of humanity, the period of applying perspective is quite brief. Perspective painting represents a virtual depiction of reality. In other words, the first instance of visualizing something virtual is perspective. People speak as if the metaverse is a significant industry today, but the virtual realization through perspective began long before the digital era. Currently, it’s only visually represented digitally. Understanding the essence of this can help you mitigate risk, even as times and circumstances evolve. - Joseph’s “just my thoughts”
For the security of the Internet service, we have been asked by the Internet service companies to set the password combined by more than 8 or 10 "uppercase letter+lowercase letter+number+special character". But it was obviously of no use. This security guideline was recommended by Bill Burr who worked at NIST in the USA, he suggested this way in his report. Furthermore, the user was required to change the initial password set regularly. Despite this measure, the best way of security to protect users' accounts was the notification of the alarm for attempted hacking when the hacker tried. We have only tried to change the keys despite the simple method meanwhile. Today, the world has begun to comprehend that the security problem is not encryption or confidentiality, but simply cyber-dominion control and communication. - Joseph's "just my thoughts"
