Mobile device forensics is a branch of digital forensics relating to recovery of digital evidence or data from a mobile device under forensically sound conditions. Mobile device forensics is a rapidly evolving field, creating exciting opportunities for practitioners in corporate, criminal, and military settings. Mobile phones facilitate everything from voice/video calls to text messaging, Web surfing, shopping and GPS navigation, music player, video recording and image/video editing. More memory is being added to mobile phones, which makes their storage capacity greater than ever. As a result, they also provide rich data and evidence for legal investigations. Call records logs, texts messages, video, internet surfing log, GPS log files and pictures help with cases ranging from ethics investigations to murder prosecutions. Mobile forensics professionals recover mobile phone evidence so that law enforcement agencies and lawyers can build or defend against cases. As with any forensic science, mobile forensics requires various technical and legal training.
