- Abstract
IPhone furnishes the functional APPs of “Voice Memo”, “WeChat” and “File”, facilitating users to forward and dump audio files across them. Usually, either forwarding or dumping can remain the audio file unchanged of its size and recorded content, yet making it changed of the metadata information and electronic data. Therefore, the audio files stored in “Voice Memo” should be authenticated with not only the routine analyses of their metadata, signal, semantics and electronic data but also source-tracing into their systemic and applicative log files resulted throughout the entire course of generation and transformation from the audio files. With a real case, an introduction was here made on how to trace into the transferring process of audio files through iPhone-stored “WeChat” log files and accordingly judge the authenticity of the relevant audio recordings synthetically.
