At its core, processing involves the extraction of metadata from electronic files and email archives and the population of a database with this metadata along with links to the corresponding files. Once created, several culling, or filtering functions can be employed. What this means to you is that many non-user-created files will be excluded from your review set. De-duplication, or flagging or exclusion of duplicate items, can also considerably reduce a review or production set. For larger cases, early case assessment (ECA) can be used to analyze, search, and report on your large data set. Then, only data that meets the user specified criteria is promoted to the processing engine. Insight also has the ability to directly process forensic images, deleted items, and many mobile device image formats.
