<p>PURPOSE:To secure surely the secret of data in spite of a simple pass word by making read out of data such as a telephone number possible when the data are pattern data of which previously set-up pass word is similar to that of trace data. CONSTITUTION:A pass word character is stored in a pass word character storing part 11. Then, a hand-written pass word character is inputted from a touch input part 2 and sent to an input character storing part 13. A coincidence circuit 14 compares the contents of the storing parts 11, 13, and when coincidence is detected, a registration vector string is read out from a character vector string storing part 12 and the sum of directional differences between the registered vector string and an input vector string in a RAM 6 is calculated and compared with a fixed value (a). When the sum of the directional differences is less than the fixed value (a), '1' is set up in an F register to form a data readable/writable state. Only when handwriting at the registration of the pass word is similar to that of the input pass word, data can be read out and written, and when both the handwriting forms are not similar, the reading and writing are inhibited.</p> |
