Digital Audio Tampering Detection Based on ENF Spatio-temporal Features Representation Learning
[article]
2022
arXiv
pre-print
Most digital audio tampering detection methods based on electrical network frequency (ENF) only utilize the static spatial information of ENF, ignoring the variation of ENF in time series, which limit ...
This paper proposes a new method for digital audio tampering detection based on ENF spatio-temporal features representation learning. ...
[19] extracted the phase features of the ENF component (ENFC) based on 𝐷𝐹𝑇 0 and 𝐷𝐹𝑇 1 , extracted the instantaneous frequency features of ENFC based on Hilbert transform, and used the SVM classifier ...
