Mobile phone forensics is a type of electronic data gathering for legal evidence purposes. This is a useful tool for investigators as a method of gathering criminal evidence from a trail of digital data, which is often difficult to delete. Extraction of deleted mobile phone files used as criminal evidence is the primary work of mobile phone forensics investigators.
Types of mobile phone forensics include taped conversations, digital phone pictures, mobile phone texts or emails, phone number lists and sometimes even mobile phone digital video recordings. Once evidence is gathered for legal purposes, it can be saved and stored to prevent deletion or damage of important digital materials through systems developed for mobile phone data extraction.
More often than not, mobile phone forensics are applied to digital data retrieval of deleted communications. These may aid legal teams or police detectives, resulting in legal evidence production and presentation.
