Secure digital forensic imaging

Secure digital forensic imaging (SDFI) is a process that ensures fast, safe and secure capture, storage and delivery of digital forensic evidence.
The process consists of three distinct parts:
# A high resolution digital imaging device configured specifically for forensic examinations. A defined photo documentation process should be followed to ensure effective and consistent evidence collection.
# Secure storage for all digital evidence using high level encryption of data. This ensures that all evidence is secure and privacy laws are strictly adhered to (Example: HIPAA).
# Telemedicine capabilities allowing evidence to be sent over the internet in digital form. All data must be encrypted to maintain privacy laws and Chain of Custody.
Background
Secure digital forensic imaging is applied in many fields but most notably by forensic nurses. True secure digital forensic imaging is normally accomplished through the use of a digital camera. A colposcope is also capable of fulfilling this process with much lower image quality as it is not a pure digital device, it is a digital device dependent on a non-digital one . Colposcope technology is based on a lens system developed primarily for cervical exams in 1925 and has been used for various forensic purposes since. Properly configured Digital cameras allow for clear, high resolution photos with and/or that cannot be achieved through the older lens systems due to their limited optics. Attaching a digital capture device to look through a colposcope's lens system will suffer the limitations inherent to the older lens system's design.
Secure digital forensic imaging describes a process that is becoming more and more popular as health systems convert from traditional documentation to paperless methods. If you take a digital picture and it is used for evidence it is deemed "forensic" and all forensic evidence must have limited access (be "secure") to adhere to applicable federal laws. If you take any digital camera, take a picture of an individual's wound, they go to court and use the picture as evidence and it is proven legally to have strictly adhered to the appropriate federal laws then the process is technically intact.
Digital imaging in forensic science
Secure digital forensic imaging is a marriage of technology and law as it is applied to the collection and handling of digital evidence. Digital images collected during exams become evidence and therefore must remain authentic (according to the Federal Rules of Evidence), meet privacy requirements (HIPAA) and the evidence must be transferred between parties in accordance with federal law (Chain of Custody). The Secure Digital Forensic Imaging process ensures legal requirements are achieved through:
* Digital SLR images of any image file format can be validated if a raw image format version exists for comparison. There is no known method of manipulating raw files.
* Privacy laws must be adhered to in order to maintain the integrity of evidence. High level encrypted storage of data (images) limits physical and visual access to the appropriate individuals.
* The chain of custody is maintained through the use of an encrypted Telemedicine system. This ensures appropriate access and secure communication channels in all instances.
Digital evidence collection should meet or exceed guidelines set by SWGIT and SWGDE to qualify as a SDFI process.
