Abstract

The system is for rendering technical or special text as being unreadable for security purposes, and involves the elimination of every 'n'th character. This may mean that every 2nd or 3rd or 4th character is omitted. A further aid to security involves transmission of the remaining characters in a special sequence or in alphabetic order.
