摘　　要：Sensors are widely applied in the collection of voice data.Since many attributes of voice data are sensitive such as user emotions,identity,raw voice collection may lead serious privacy threat.In the past,traditional feature extraction obtains and encrypts voice features that are then transmitted to upstream servers.In order to avoid sensitive attribute disclosure,it is necessary to separate the sensitive attributes from non-sensitive attributes of voice data.Motivated by this,user-optional privacy transmission framework for voice data(called:Voice Fence Wall)is proposed.Firstly,we provide user-optional,which means users can choose the attributes(sensitive attributes)they want to be protected.Secondly,Voice Fence Wall utilizes minimum mutual information(MI)to reduce the correlation between sensitive and non-sensitive attributes,thereby separating these attributes.Finally,only the separated non-sensitive attributes are transmitted to the upstream server,the quality of voice services is satisfied without leaking sensitive attributes.To verify the reliability and practicability,three voice datasets are used to evaluate the model,the experiments demonstrate that Voice Fence Wall not only effectively separates attributes to resist attribute inference attacks,but also outperforms related work in terms of classification performance.Specifically,our framework achieves 89.84%accuracy in sentiment recognition and 6.01%equal error rate in voice authentication.
