Document Type and Number:
Japanese Patent JP4390234
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To insure reliability of data and to cope with change of data by enciphering measured data, housing the check code in a memory means, and decoding the housed enciphered data and the check code. SOLUTION: A processing means 2 displays data taken in by an input means 1 by a display means 3 and simultaneously encipheres them. For example, when the data is 123.45, it is multiplied by 8 and reversely arranged to be 6.789, the check sum 30 of the enciphered data is taken, and both are housed in a memory means 4. In this way, respective measured data are in order enciphered and together with the check code housed in the memory means 4, and when required, the respective housed enciphered data and the check code are decoded and restored, and printed by a recording means 5 to display on a display means. Because the housed data is enciphered, it can not be used as it is as the data for guarantee, and because the check code is generated from the enciphered data, in the case of change of the data, it can be immediately discriminated, and the change can be prevented.
