Abstract
1. 청구범위 기재된 발명이 속함 기술분야1. The claimed invention belongs to the technical field
암호를 이용하여 데이터를 변형시켜 변조 송신하고 변형된 데이터를 수신하여 암호를 풀어 복조하는 기술이다.It is a technology that modulates and transmits data by using encryption, modifies and transmits the data, and decrypts and demodulates the received data.
2. 발명이 해결하고자 하는 기술적 과제2. Technical problem to be solved by the invention
통신중에 교환망의 혼선이나 사용자의 실수로 인해 원하지 않은 곳으로 중요한 자료가 보내질 수 있고 또한 원하지 않는 불필요한 화상데이타 즉, 광고나 선전물 등이 수신되는 문제를 해결한다.It solves the problem that important data can be sent to undesired place due to confusion of the switching network or user error during communication, and unwanted unwanted image data, ie advertisement or advertisement.
3. 발명의 해결방법의 요지3. Summary of Solution to Invention
설정된 암호를 등록하는 과정과, MH 또는 MR코딩한 화상데이타를 4비트 단위호 저장하는 과정과, 상기 등록한 4비트단위의 암호와 상기 저장한 4비트단위의 MR 또는 MH코딩 화상데이타를 독출한 후 배타논리합하여 암호와 시키는 과정과, 상기 암호와 시킨 화상데이타를 변조 송신하는 과정과, 전화라인을 통해 입력되어 복조된 이치화 데이타를 4비트 단위로 저장하는 과정과, 상기 등록한 4비트단위의 암호와 상기 저장한 4비트단위의 이치화 데이터를 독출한 후 배타논리합하여 암호를 해독하는 과정과, 상기 암호가 해독된 데이터 MH 또는 MR디코딩하여 프린팅하는 과정으로 이루어져 있다.Registering the set password, storing the MH or MR coded image data in 4-bit units, reading the registered 4-bit unit password and the stored 4-bit MR or MH-coded image data A process of exclusively logically encrypting and encrypting the data, modulating and transmitting the coded image data, and storing the demodulated binarized data input through a telephone line in 4-bit units; The process of reading the stored 4-bit unitized data and then performing exclusive logic to decrypt the decrypted data, and the process of printing the decrypted data MH or MR by decoding.
