Disclosed is a method to restrain tampering of electronic Karte (medical record) in a hospital. In the past, "Karte" was hand-written by a doctor and filed in the form of paper media in a hospital. However, these days, some of the Kartes are input using personal computers or electronic devices and all the Karte data is stored in storage of computers. In such a case the Karte is electronic data and is not necessarily be in a form of paper document. We call the Karte "electronic Karte." Kartes in hospitals, which record the past diagnostics and treatments, should be kept unchanged and archived for a certain period of years, being regulated by laws. Sometimes, Kartes are used for important evidences of medical suites. When a Karte is hand-written, it was not easy to tamper (alter) the contents of the Karte because, altering the hand-written document without noticeable vestige is relatively difficult. On the other hand, when a Karte is electronic, it is quite easy to tamper (alter) a part of the Karte because, the data in a computer can be easily edited.
