This is especially true of cryptographic hash functions, which may be used to detect many data corruption errors and verify overall data integrity; if the computed checksum for the current data input matches the stored value of a previously computed checksum, there is a very high probability the data has not been accidentally altered or corrupted.
For example, this could be used to find duplicate billings of invoices within the sales ledger. Matching (Fuzzy): Specifies whether the product supports finding matching items for a specific field using fuzzy comparison. For instance, values compared are similar but not exactly the same (e.g., using Levenshtein matching).
One method for deduplicating data relies on the use of cryptographic hash functions to identify duplicate segments of data. If two different pieces of information generate the same hash value, this is known as a collision. The probability of a collision depends mainly on the hash length (see birthday attack).
For instance, when customer data are duplicated and attached with each product bought, then redundancy of data is a known source of inconsistency since a given customer might appear with different values for one or more of their attributes. [4]

Record linkage (also known as data matching, data linkage, entity resolution, and many other terms) is the task of finding records in a data set that refer to the same entity across different data sources (e.g., data files, books, websites, and databases).
A new survey found that 1 in 5 adults “who say they have no personal or family history of heart attack or stroke,” reported “routinely” taking a low-dose aspirin
