Bog'liq DigitalEvidence Common Terms
Common terminology is critical in the digital evidence world. The Scientific
Working Group on Digital Evidence (SWGDE) in collaboration with the
Scientific Working Group on Imaging Technology (SWGIT) has developed and continuously maintains a glossary of terms used within the digital and multimedia disciplines. SWGDE has used ASTM International, a recognized standards organization, to establish international acceptance of terminology.
SWGDE/SWGIT’s full glossary is available online:

Some common terms include:
Cloud Computing -‐ software, applications and digital storage that is accessed on the Internet through a web browser or desktop or mobile app. The software and user's data are stored on servers at a remote location.
Data -‐ Information in analog or digital form that can be transmitted or processed. Data Extraction -‐ A process that identifies and recovers information that may not be immediately apparent.
Encryption -‐ procedure that converts plain text into symbols to prevent anyone but the intended recipient from understanding the message.
File Format -‐ The structure by which data is organized in a file.
Forensic Wipe -‐ A verifiable procedure for sanitizing a defined area of digital media by overwriting each byte with a known value; this process prevents cross-‐contamination of data.
Handheld (Mobile) Devices -‐ Handheld devices are portable data storage devices that provide communications, digital photography, navigation systems, entertainment, data storage, and personal information management.
Hash or Hash Value -‐ Numerical values that represent a string of text (search term), generated by hashing functions (algorithms). Hash values are used to query large sums of data such as databases or hard drives for specific terms. In forensics, hash values are also used to substantiate the integrity of digital evidence and/or for inclusion and exclusion comparisons against known value sets.
