In the data recovery sector there are many differences in the services that are offered. The most notable difference is between those providing basic data recovery software and trained Forensic Examiners that offer Equipment Based Forensic Data Extraction and Analysis
The biggest mistake you can make is to use the wrong tool for your task at hand and ruin your chances of recovery. There are new data recovery software programs being released on an almost daily basis. Sometimes free, sometimes paid, they promise to retrieve your deleted data at the click of a button or the swipe of a finger.
The problem with most software recovery programs is that they must be installed on the very device you are trying to recover data from, thus your phone mustthen make room in its memory for this program. Oftentimesthis overwrites the very data you’re trying to retrieve. Most software almost always requires you to update your phone to the latest operating system to ensure its compatibility with your device. This practice alone can drastically lower your chances of a successful recovery. Additionally, many software products require you to root the phone in order to allow the program access to your phones memory. However, whenthe phone is rooted/gaol broken,it must wipe everything and replace it with a custom operating system. Doing so overwrites almost all of the deleted data.
At NSI we use proprietary hardware capabilities in conjunction with forensically sound methodologiesto perform our forensic data extraction investigations following strict forensic principles. This hardware is the same hardware that law enforcement agencies worldwide use for their digital forensic investigations. The equipment does not install anything whatsoever on your device. The data flow is a one-way connection that extracts the raw binary data from your device, leaving it intact and ready for analysis.
There are multiple factors that will determine the success of the extraction. These include: the way in which the device was used since the data was deleted; if there were any software updates or factory resets; the amount of memory on the device; or if there is physical damage to the device.
Furthermore, because of the forensic data extraction capabilities and processes we follow at NSI we can provide comprehensive court reports that enable the data we’ve extracted to be legally admissible in court. During our forensic processes the evidence extracted will have specific forensic identifying algorithms applied to the report which enables that data to be legally admissible in court. Assigning these algorithms provide digital files with a unique identifier that corresponds to its contents. This helps to ensure that the evidence hasn’t been tampered with and verifies the chain of evidence and custody. These processes and capabilities are what separates forensic data extractions from standard data recovery services,don’t take the risk.
