A fake face detection system using a hybrid discrete Chebyshev wavelet transform and a convolutional neural network.
Abstract
The widespread use of artificial intelligence has led to the exploitation of
this development in the development of manipulation processes, for
example, face manipulation with deep learning, which poses a great danger
and threat to information safety and digital security. This work proposes a
new hybrid system in which a new filter extracted from discrete Chebyshev
wavelet transform (DChWT) ( )is effectively integrated with an
artificial convolutional neural network and employed in the process of
detecting face forgeries. The capabilities and characteristics of the
proposed waves were utilized, namely the orthogonality property and the
multi-precision analysis property of waves in the spatial frequency domain
in spatial learning in artificial convolutional networks. The performance of
the proposed system in this work stands out in the superior performance of
the Face Forensics standard, with the achievement of 99.98% accuracy
with a recall value of 99.89%, and 99.91% precision. The confusion
matrix, developed after comprehensive analysis, serves to evaluate the
classification performance of a dataset containing both real and fake
datasets. This evaluation aims to achieve system efficiency by identifying
the hybrid system's strengths in detecting diverse manipulation techniques
and challenges. In this study, the hybrid system outperformed modern
methods by 2.3% in AUC-ROC, achieving high computational efficiency
within the required timeframe and maintaining this efficiency
