A data processing system for voice calls

Abstract

The present invention provides a data processing system during a voice call, comprising: a first output module for outputting a first authorization code; a first prompt module for prompting to read the first authorization code aloud; a first security chip for To obtain the reading result of the first authorization code, to obtain the first sound information; to encrypt the first sound information, to obtain the first encrypted data, and to send the first encrypted data; after obtaining the first confirmation instruction, start the voice call Perform encryption and decryption operations; the second output module is used to output the second authorization code; the second security chip is used to decrypt the first encrypted data after receiving the first encrypted data to obtain the first decrypted data; the second The playback module is used to play the first decrypted data; the second prompt module is used to prompt to confirm the first decrypted data; the second security chip is also used to start encrypting and decrypting the voice call after receiving the second confirmation instruction operate.

Description

technical field

[0001] The invention relates to the field of electronic technology, in particular to a data processing system for voice calls. Background technique

[0002] In the prior art, voice calls between users may be monitored, so current voice calls have security risks. Aiming at security risks, the method adopted in the prior art is to encrypt the voice through the call key stored in the TF card on the mobile phone, so as to realize the protection of the voice call. However, in practical applications, if the call terminal is installed with malware, hackers can use the malware to steal the call key in the TF card, and then crack the encrypted voice information, resulting in the risk of voice data leakage of the call terminal. The voice encryption operation is a technical problem to be solved urgently; in addition, in the prior art, there is a possibility of being monitored in a voice call, so reducing the possibility of a voice call being monitored is also a technic...
