As almost every element in our lives has been embedded in the digital domain, it is the integral part of all modern criminal investigations. As the volume of computer crimes is ever increasing along with dependency on the electronics, it is mandatory for law enforcement agencies to be equipped with the right methodologies and technology to seize, search, acquire, and preserve the electronic evidence. Digital Forensics acts as an interface between criminal investigation and the field of computer related crimes through application of scientifically methodical techniques and tools for the recovery of appropriate evidence from computers, cell phone, networks and various storage mediums 1 .In this investigation the importance of Digital Forensics is described. Digital Forensics play an extremely important role in investigation by identification of digital evidence, rebuilding of crime scenes and the presenting of evidence in court to assure conviction of criminals. Investigation procedures incorporate forensic activities as acquisition, preservation, examination and analysis of evidence from various sources, and eventually presenting the data in court in an acceptable way 2 . Digital devices like smartphones, personal computers, cloud storage systems, network systems, etc contain vast amount of information to establish a relation between suspects and the crimes being investigated and to determine the time of the crime. Many invisible digital traces of crime are always helpful in the investigation process 3 . The main challenges for digital forensics come from encrypted data and anti forensic tools 4 .Digital Forensics has emerged as the scientific discipline which will lead criminal investigations by identifying, acquiring, analyzing, and presenting digital evidence collected from electronics and network devices. Since both the public and criminals are increasingly reliant on the technology of the digital age, the presence of electronic evidence can be critically important in investigations related to cyber crimes, fraud, homicides and other crimes in which digital traces have been left 5 . Digital forensic tools can be used to acquire a forensically sound image of a deleted file, recorded communication, location information and metadata which can be used as a digital evidence in the court 4 .
