A large majority of people use these devices for advanced technological advantages they have on offer. These devices allow easy access Provide rapid flow of information Connecting people in different corners of the globe Help preserve the anonymity and are not well regulated
These modern devices allow progress and the majority of people to improve their productivity with these. However, these advantages are that criminals are looking to advance their destructive acts. Cyber crime has increased or rather soared to such an extent that forensic analysts now face millions of cases each year. A few decades back, they had just a few hundred cases to review.
The increasing number of cases are vast and varied in nature. Forensic analysis involves the identification, retrieval, preservation and interpretation of information from computers or mobile phones for legal purposes. These results are presented in the courtroom and they help solve cases where no fingerprints, eyewitness or DNA tests were available or common.
The cases varied requiring inquest
The cases that require forensic investigation are matters of cybercrime. These illegal acts are committed using the Internet and network operations. As mentioned cases are varied in nature and may involve terrorism, the promotion of pornography, white collar crime or even violent crimes such as kidnapping and murder.
Business schools require forensic investigation to apprehend the employees who engage in, espionage - is committed by a person in management or other executives, who flew highly confidential and sensitive of the information and pass on trade secrets
The information theft - employees to make inappropriate duplication or unauthorized use of corporate data for sale
Cybercrime company information Sabotaging driven motive of revenge, personal gain or to gain an advantage in winning the competition
Other activities of the crime - with false, corruption, e-harassment, etc., during working hours
investigators to solve these cases by recovering data from physically or logically damaged media such as computers or mobile phones. Computer forensic investigation is the computer forensics, and forensic investigation of mobile mobile is legal.
Computer Forensics
Computer forensics involves the use of tools and specialized techniques for recovery and preservation of data from computers. The nature of the case may require access and review of data (which could be presumed lost) and performing a technical analysis to assist law enforcement services. The expertise involved in computer forensic analysis is more specialized in nature compared to the normal data recovery and data preservation. The survey must follow all the rules intended to preserve the integrity of data as evidence.
All investigations must be conducted within the rules of the Association of Police Officers (ACPO) and the National Hi Tech Crime Unit (NHTCU) Correct procedures must be used to collect data. These data should be well preserved evidence. After identifying the information required on the computer, the original media must not be worked. You need a computer analysis to the implementation of recovery work. All procedures conducted during the examination must be reproducible.
Mobile Phone Forensics
Different versions of cell phones require different techniques for recovering data. If the device is supported by forensic software to automatic analysis is performed. It is followed by manual verification. When the device is not supported by forensic software to a manual check is performed. If a memory card is present in the handset, computer forensic techniques are used for data recovery.
Data retrieved from mobile phones is used to show communication between suspects, victims and co conspirators. However the recovery of information from mobile phones is not as easy as retrieving data from computers. The software used on cell phones differ from manufacturer to manufacturer and even between two sets of the same brand. The data available on mobile is typically encrypted or hidden. It is also possible to delete messages if the phone is connected to the cellular network.
Using digital cameras in crime has increased considerably. The evolution of crime is also hampered by the rapid development of techniques to increase the evidence and apprehend criminals.
