Title:
SECURITY SYSTEM FOR TEXT FILE
Document Type and Number:
Japanese Patent JPS62251944
Kind Code:
A
Abstract:
PURPOSE: To improve the security capacity by converting the character code of a text file to an unprintable code.
CONSTITUTION: A conversion instruction part 3 accepts the text conversion instruction from a user to start a text converting part 1. A text 4 before conversion is inputted to the converting part 1, and the converting part refers to a conversion table 2 to convert the character code of the text to an unprintable code and outputs a converted text 5. If an output instruction part 7 accepts the next output instruction from the user to start an output part 6 and outputs the text 5 to an output device 8, the text 5 is not printed by the output device because the text 5 has the unprintable code.
