The cyber crimes such as online banking fraud, credit card theft, child pornography, intellectual property theft, identity theft, unauthorized intrusion, money laundering, digital piracy etc. are growing rapidly with technology. Desktops, smartphones, laptops, digital cameras, GPS devices and even watches all can be used to aid a fraud. All this devices leave behind a digital footprint. Gathering electronic evidence and preserving it requires a special set of deliberations. Without a complete understanding of digital forensics, evidence could be compromise and which may cause evidence inadmissible in the court. To analyze the digital crime, the forensic technique is used. It is use to track where exactly the crime has been taken place and where the valuable data is hidden. To analyze the data and to recover the deleted or hidden data from the digital devices, the digital forensic tools are used. Paper presents the comparison of three digital forensic tools WinHex, Active file recovery, and ProDiscover Basic based on the parameters such as File examination, Log examination, Deleted File Indexing, Memory Dump Analysis, supported file systems, supported disk images.
