Problems solved by technology

However, when encrypting or replaying (decrypting) the audio data encrypted by means of a password, it is necessary to input a password, which is cumbersome to operate and reduces the convenience of audio data encryption / decryption; Fingerprint information needs to be input when encrypting or replaying (decrypting), and the fingerprint information entered by the user is easily affected by the external environment (for example, dirty fingers, sweat on the fingers), resulting in the failure of audio data encryption / decryption, resulting in Low accuracy of audio data encryption / decryption
[0004] Therefore, the existing audio data encryption / decryption method causes the convenience and accuracy of audio data encryption / decryption to be low, and needs further improvement

Embodiment 1

[0062] This embodiment will be described from the perspective of an audio data encryption device. Specifically, the device may be integrated into a terminal, and the terminal may be a mobile terminal such as a smart phone or a tablet computer.

[0063] An audio data encryption method, comprising: receiving an encryption request, the encryption request carrying original audio data to be encrypted, obtaining corresponding preset audio data according to the encryption request, obtaining encrypted data according to the preset audio data, and obtaining encrypted data according to the encrypted data Encrypt the original audio data to obtain encrypted audio data.

[0064] Such as figure 1 As shown, the audio data encryption method, the specific process can be as follows:

[0065] S101. Receive an encryption request, where the encryption request carries original audio data to be encrypted.

[0066] In specific applications, there are many ways to receive encryption requests. For examp...

Embodiment 2

[0100] According to the audio data encryption method described in Embodiment 1, further examples will be given below to describe in detail.

[0101] In this embodiment, the audio data encryption device is integrated in the mobile terminal, and the audio data encryption method in the mobile terminal is taken as an example for detailed description.

[0102] Such as figure 2 As shown, the audio data encryption method, the specific process can be as follows:

[0103] S201. Receive an encryption request, where the encryption request carries original audio data to be encrypted.

[0104] Specifically, the encryption request can be recorded by the user using the microphone on the mobile terminal, and the security module (for example, the rights management module) on the mobile terminal automatically sends out when the recording ends, and the processor of the mobile terminal receives the encryption request and processes it. , the encryption request carries the original audio data (t...

Embodiment 3

[0126] This embodiment provides an audio data decryption method, which will be described from the perspective of an audio data decryption device. Specifically, the device may be integrated into a terminal, and the terminal may be a mobile terminal such as a smart phone or a tablet computer.

[0127] A method for decrypting audio data, comprising: receiving a decryption request, the decryption request carrying encrypted audio data to be decrypted, obtaining corresponding preset audio data according to the decryption request, obtaining encrypted data according to the preset audio data, and obtaining encrypted data according to the encrypted data The encrypted audio data is decrypted to obtain original audio data.

[0128] Such as image 3 As shown, the audio data decryption method, the specific process can be as follows:

[0129] S301. Receive a decryption request, where the decryption request carries encrypted audio data to be decrypted.

[0130] In a specific application, th...

Abstract

Embodiments of the present invention provide audio data encryption and decryption methods and apparatus. The audio data encryption method includes the steps of receiving an encryption request; acquiring corresponding preset audio data according to the encryption request; acquiring encrypted data according to the preset audio data; and encrypting original audio data according to the encrypted data, so as to obtain encrypted audio data. According to the method, the encrypted data is acquired according to the preset audio data, and then the original audio data is encrypted so that the encrypted audio data is obtained. The whole process is performed automatically, a user does not need to input the encrypted data, and the obtained encrypted data has high stability and is not affected by an external environment, therefore, compared with the prior art, the method improves convenience and accuracy of audio data encryption.

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular to an audio data encryption / decryption method and device. Background technique [0002] Today's society has entered an era of rapid information development. People often need to save various information. It is a very convenient way to save information through audio data. At the same time, since everyone has a lot of private information, and sometimes hopes that the information saved by oneself cannot be known by others, therefore, the saved information needs to be encrypted. [0003] At present, when encrypting audio data, it is often encrypted by adding a password to the audio data, or adding user's fingerprint information to the audio data for encryption. However, when encrypting or replaying (decrypting) the audio data encrypted by means of a password, it is necessary to input a password, which is cumbersome to operate and reduces the convenience of audio data encrypti...
