Audio input encryption and decryption method

Abstract

The invention discloses an audio input encryption and decryption method. The encryption method is characterized by, to begin with, establishing data that needs to be kept secret; then, inputting a decryption instruction with audio and editing the decryption instruction with text; and setting data content that requires audio input encryption. The decryption method is characterized by, to begin with, when entering data category set to require audio input encryption, speaking out a decryption instruction; and then, judging whether the spoken decryption instruction is matched with the content of the decryption instruction input with audio and the decryption instruction edited with text, and displaying the corresponding content according to the results. The method combines advantages of a pre-recording mode and a non-pre-recording mode, and overcomes the defects respectively.

Description

technical field [0001] The invention relates to the technical field of encryption, in particular to an audio input encryption and decryption method. Background technique [0002] Nowadays, the audio input function is being used more and more on mobile communication devices such as mobile phones. The audio input function is subdivided into many specific applications, such as audio input dialing, audio input query, audio input reading, etc. As a personal item with strong privacy, mobile phones also widely use the method of audio input encryption. If the current audio input encryption uses the pre-recording method, the user needs to pre-record a piece of audio input to the mobile phone as an instruction for audio input decryption. The input phoneme data is compared with the pre-recorded audio input, and the user is allowed to enter the module only if it is completely consistent with the pre-recorded phoneme data, otherwise the user cannot enter. If the non-pre-recording meth...

Therefore, for the pre-recording method, each person’s pronunciation is different, and the phoneme data converted into the same sentence when it is recorded into a decryption command is also different, resulting in that although the decryption command is known, it can be read on the mobile phone where someone else has recorded the decryption command. No matter how you tell the decryption command, it cannot be decrypted; for non-pre-recording methods, as long as you know someone else’s decryption command, even if some modules of the mobile phone have audio input encryption, it is useless
