WebAs adjectives the difference between bitwise and bytewise is that bitwise is being an operation that treats a value as a series of bits rather than a numerical quantity while … WebAccording to NIST SP 800-168, ‘‘approximate matching is a promising technology designed to identify similarities between two digital artifacts’’ (Breitinger et al., 2014a). This identiﬁcation of similarities between two or more artifacts can happen on three different levels of abstraction: bytewise, when the comparison re-

WebFeb 1, 2024 · Approximate matching functions allow the identification of similarity (bytewise level) in a very efficient way, by creating and comparing compact representations of objects (a.k.a digests). WebOct 15, 2024 · Approximate matching has become indispensable in digital forensics as practitioners often have to search for relevant files in massive digital corpora. The research community has developed a variety of approximate matching algorithms. However, not only data at rest, but also data in motion can benefit from approximate matching.
