English term or phrase:Hash Analysis
W moim tekscie, który dotyczy analizy zdjęć i filmów znalezionych na karcie pamieci, jest taki fragment :
A further process was carried out called "Hash Analysis". A "hash" can be described as a unique fingerprint, in this case, a unique "digital fingerprint" of each image. During the process of Hash Analysis the images are compared in order to establish if certain images appear on other exhibits.
Ze slownika, dla wyjasnienia:
Hash Analysis - The comparison of Hashes generated in a case against a known hash library.
Hash (Md5) - An MD5 hash value is a number generated through a defined algorithmic formula which generates a unique identifier for any file. This value effectively becomes a digital fingerprint allowing the file to be uniquely identified. The odds that two files with differing contents would generate the same hash value are 2128. By generating hash values of known files (e.g. files known to part of a legitimate piece of software or alternatively a file known to contain indecent material) and compiling these into a library, files analysed as part of a case and subsequently cross referenced against a known hash library, Files can be included or excluded as appropriate from the case.
