  1.1 What isMobile Forensics ? • Mobile forensics is a branch of digital forensics simply, it is a science of recovering different kinds of evidence from mobile phones . It helps investigators significantly to reach to the criminal.
• 3.
  1.2 Data typesthat could be available on Mobile Devices .. • Contact Numbers • Record of calls, sms, mms,and details about them. • Sounds • E-mail messages • Notes • Calendar
• 4.
  1.3 Several proceduresmust be done when the scene of crime is cordoned • Make all people far away from crine scene . • Drawing or take photographs of the scene • Record the status and location of each device exist in the scene. • Avoid any activity that could affect the origin of the evidence. • The evidences in the crime not only mobile any other forensics evidences should be collected .
• 5.
  2.1 The majorsteps of Mobile Forensics • Preservation • Acquisition • Examintaion • Analysis • Reporting
• 6.
  2.1.1 PRESERVATION • Thisstep is the first and includes cordon off the scene of crime and seizing the devices of suspect without altering the contents of it .
• 7.
  2.1.2 ACQUISITION • Itmeans take all information about mobile devices existing in the scene - • Identication of the device. • Selecting the tool that would be use.
• 8.
  2.1.3 EXAMINATION • Thisstep is to get the digital evidences from mobile phones whether the evidences are exist clearly or hidden by using scientific methods.
• 9.
  2.1.4 ANALYSIS • Theanalysis process looks to the results of the previous process. Then analysis them.
• 10.
  2.1.5 REPORTING • Thisis the last step in the forensics process. It is summarized in the preparation of a report that contains all results ,procedures or steps that have been done .

  3.1 Techniques usedto insulating a mobile from communications: • Isolate the entire crime scene from the network . • Use a shielded containers . • Using substitute SIM: put another SIM rather than the original to make the device outside the coverage.
• 12.
  3.2 Procedure toensure of Mobile devices: when they transported to the laboratory • You should put them in a hard containers to keep them secure from damage in the case containers facing the colloision . • Also to preserve the possibility of non-pressure buttons of the mobile phones.

  4.1 Challenges relatedto mobile devices. • Find mobile device as immersed in a liquid- In this case ,battery should be removed and put the device in appropriate container. • Find mobile device in a damaged state-This case may doesn't present extraction data from the device . This should brings to the lab in order to examine it carefully. • Devices which closedby the secret numbers-can solved by either investigative ,software or hardware methods .

  5.1 Importance andMotivation • In the recent years , mobile devices are spread widely ,we can say every person had a mobile device without considering to the type and the model of the crime. • Sometimes ,we must note the several people use mobile phones to do purpose like the crimes . Therefore, these mobile phones can act as main witnesses of these purposes. • This leads to the need to recover data from mobile phones for use it as evidences of these crimes . • Hence,the implememtation of mobile forensic becomes very impotant ,and the research in this area is very intresting .
