Speaker Identity Tracing Scheme in 5G Communication Based on Fingerprint

With the widespread popularization and application of 5G communication technology,concerns about security issues of 5G communication system are rising.To solve the difficulty of identity tracing caused by counterfeiting,forging or denying of speaker identity,in this article,a speaker identity tracing scheme for 5G remote communication is proposed.The biometric fingerprint information of speaker has been acquired from smartphone before calling.During the calling,the biometric fingerprint information which represents speaker identity is embedded into the voice signal using digital watermarking technology,thus the relevance between the speaker identity and the speech is established.Once the speaker identity is queried,it can be traced by extracting the biometric fingerprint information from speech signal.The performance of extracting fingerprint from speech which contains fingerprint information and is transferred through wireless channel aftermodulated by Generalized Frequency Division Multiplexing is presented. The simulationresults show that, the fingerprint extraction performance of the scheme in 5G modulated byGeneralized Frequency Division Multiplexing outperforms than that in 4G communicationsystem, and it has potential application worth for preventing telecommunication fraud in thenext generation of mobile communication.
