example 1
[0022] Example 1: Central processing unit CPU3-1, through function selection interface 3-8, when obtaining the command of screen coding information transmission, the program in the fixed memory 3-10 is first read from the human body code recognizer interface 3-3 The human body code of the sender is combined with the code of the authorized person embedded in the file by the screen code in advance, and if the same result is obtained, the standard or specific computer code can be sent through the interface 3-6 of the encryptor. Enter the interface conversion of the encryptor 1-6 in the interface converter of the encryptor 1-5, until the information is launched. Otherwise the program in the non-volatile memory 3-10 will issue a command to deny the launch. Here, the circuit 3 of the screen code microprocessor 1-1, 2-1 can be a microprocessor for the screen code transmitting terminal.
example 2
[0023] Example 2: when the central processing unit CPU3-1 obtains the command of the screen coding information display through the function selection interface 3-8, similarly, the program in the fixed memory 3-10 is first read from the human body code recognizer interface 3-3 Read the human body code of the reader, and combine it with the code of the authorizer embedded in the file with the screen code in advance. If a consistent result is obtained, the standard or specific computer code can be sent through the display interface 3-4. into the display for display. Otherwise the program in nonvolatile memory 3-10 will issue a command to refuse to display. Here, the circuit 3 of the screen coding microprocessors 1-1, 2-1 can also be a microprocessor for a screen coding display terminal.
[0024] The encrypted information received by the receiver 2-7 is decrypted by the decryptor 2-6 and becomes a standard computer code, and then sent to the circuit 3 of the screen coding micropr...
example 3
[0026]Example 3: when the central processing unit CPU3-1 obtains an order for screen coding information printing through the function selection interface 3-8, the program in the fixed memory 3-10 is first read from the human body code recognizer interface 3-3 The recipient's human body code is combined with the code of the authorizer embedded in the file with the screen code in advance, and if a consistent result is obtained, the program in the fixed memory 3-10 converts the standard computer code into the screen Encode and print out the received information in a covert way of screen coding through the printing interface 3-5. Otherwise the program in the fixed storage 3-10 will issue a command to refuse printing. Here, the circuit 3 of the screen code microprocessors 1-1, 2-1 may be a microprocessor for a screen code receiving terminal.
