Digital Forensic Imaging creates a bit-for-bit clone of digital evidence, following legal chain of custody procedures that result in viable evidence that can be analyzed and used in court.
One absolute rule of forensic data is: Do not modify original electronic media. Therefore, an early step in the process of analyzing electronic evidence is making an exact replica, also known as a clone or a mirror image, of the media in question. This way, the original evidence is not compromised in any way, but the analysis of the cloned data will carry the same weight as if it were performed on the original evidence.
There are several highly detailed technical and legal considerations for making an effective clone. Without expert knowledge of the technical process and legal requirements of digital forensic imaging, the evidence obtained will be useless. Therefore, you should always have an experienced, objective, and non-biased third party to handle this step for you.
For example, it’s imperative to validate the authenticity of the data. This can be obtained, for instance, by making an MD5 hash of the data in question. In layman’s terms, this is a small, unique code generated from analysis of a large volume of data, and any change to the data (even as minor as adding a dash or a period) would result in a completely different MD5 hash code.
Documenting and presenting these codes is just one of many steps to guarantee the veracity of the data in a way that will stand up in court.
We strongly suggest letting Expert Data Forenics handle this all-important step of gathering, imaging, and documenting the digital evidence that’s so critical to you. Make sure you preserve the chain of custody and avoid legal dismissals that can result from improper handling of digital evidence.
