Combining Automatic Speaker Verification and Prosody Analysis for Synthetic Speech Detection
Luigi Attorresi, Davide Salvi, Clara Borrelli +2
The rapid spread of media content synthesis technology and the potentially damaging impact of audio and video deepfakes on people's lives have raised the need to implement systems…
H4VDM: H.264 Video Device Matching
Ziyue Xiang, Paolo Bestagini, Stefano Tubaro +1
Methods that can determine if two given video sequences are captured by the same device (e.g., mobile telephone or digital camera) can be used in many forensics tasks. In this pape…
An Overview on the Generation and Detection of Synthetic and Manipulated Satellite Images
Lydia Abady, Edoardo Daniele Cannas, Paolo Bestagini +3
Due to the reduction of technological costs and the increase of satellites launches, satellite images are becoming more popular and easier to obtain. Besides serving benevolent pur…
TIMIT-TTS: a Text-to-Speech Dataset for Multimodal Synthetic Media Detection
Davide Salvi, Brian Hosler, Paolo Bestagini +2
With the rapid development of deep learning techniques, the generation and counterfeiting of multimedia material are becoming increasingly straightforward to perform. At the same t…
Speaker-Independent Microphone Identification in Noisy Conditions
Antonio Giganti, Luca Cuccovillo, Paolo Bestagini +2
This work proposes a method for source device identification from speech recordings that applies neural-network-based denoising, to mitigate the impact of counter-forensics attacks…
Splicing Detection and Localization In Satellite Imagery Using Conditional GANs
Emily R. Bartusiak, Sri Kalyan Yarlagadda, David Güera +4
The widespread availability of image editing tools and improvements in image processing techniques allow image manipulation to be very easy. Oftentimes, easy-to-use yet sophisticat…
Forensic Analysis and Localization of Multiply Compressed MP3 Audio Using Transformers
Ziyue Xiang, Paolo Bestagini, Stefano Tubaro +1
Audio signals are often stored and transmitted in compressed formats. Among the many available audio compression schemes, MPEG-1 Audio Layer III (MP3) is very popular and widely us…
Detecting GAN-generated Images by Orthogonal Training of Multiple CNNs
Sara Mandelli, Nicolò Bonettini, Paolo Bestagini +1
In the last few years, we have witnessed the rise of a series of deep learning methods to generate synthetic images that look extremely realistic. These techniques prove useful in…
Amplitude SAR Imagery Splicing Localization
Edoardo Daniele Cannas, Nicolò Bonettini, Sara Mandelli +2
Synthetic Aperture Radar (SAR) images are a valuable asset for a wide variety of tasks. In the last few years, many websites have been offering them for free in the form of easy to…
