Abstract

A dynamic spectrum audio encryption and decryption device is connected to a cell phone. The dynamic spectrum audio encryption and decryption device generates a communicating signal and encrypts the communicating signal so as to send to the cell phone. A remote cell phone received the communicating signal and sent to a corresponding remote dynamic spectrum audio encryption and decryption device and decrypts the communicating signal to generate a vocal voice output.

Claims

1. A dynamic spectrum audio encryption and decryption device being wirelessly connected with a cell phone, wherein

the dynamic spectrum audio encryption and decryption device receives a voice or video signal from a user, generates a communicating signal based on the voice or video signal, transmits the communicating signal to the cell phone after an encryption procedure processed;

and

the dynamic spectrum audio encryption and decryption device receives a remote communicating signal from the corresponding cell phone, the communicating signal is played to the user after processed with the decryption procedure.

2. The dynamic spectrum audio encryption and decryption device as claimed in claim 1, wherein the cell phone and the dynamic spectrum audio encryption and decryption device is bluetooth connected.

3. The dynamic spectrum audio encryption and decryption device as claimed in claim 1, wherein the dynamic spectrum audio encryption and decryption device is an ear phone or a head phone.

4. The dynamic spectrum audio encryption and decryption device as claimed in claim 1, the encryption procedure has steps comprising of:

encoding at least partial an audio frame of the communicating signal;

processing an anti-compress analysis to the communicating signal, and separating a specific frequency or audio frame in the communicating signal;

classifying the communicating signal being separated and rearranging the communicating signal to form multiple spectrum matrixes;

generating a dynamic key and encrypting the spectrum matrix with using the key;

rearranging the audio frame to generate the communicating signal with a synchronic signal; and

transmitting the rearranged communicating signal.

5. The dynamic spectrum audio encryption and decryption device as claimed in claim 4, wherein every spectrum matrix comprises different amount or length of audio frame.

6. The dynamic spectrum audio encryption and decryption device as claimed in claim 5, the length of the dynamic encryption/decryption key is generated randomly.
