A ‘transaction’ is an act of debt between parties. The seller owes goods to the buyer (performance debt), and the buyer owes money to the seller (monetary debt). A transaction is considered complete when the debt is settled and the promise to owe each other is called a ‘contract.’ Thus, a good trader or businessman excels at making and repaying debts. When it comes to debt, the type of debt matters. Anyone who misjudges this should not engage in business. - 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"
