Data hashing definition

WebThe term hashing refers to the transformation of a dataset of any size into a string with a fixed, shorter length, which references the original dataset. By means of a hash function, the individual elements from the dataset are initially assigned to a key and then to the hash values, which represent the original data in a certain way. WebMay 8, 2024 · INTERPRETATION: Data hashing is done by using a hash function, which converts a field into a condensed fixed-value representation, the so called hash value. For data security applications this requires that the hash function is collision-resistant, which means that it is very hard to find data that will generate the same hash value.
