US Patent 9652512 Secure matching supporting fuzzy data

Provided are techniques for secure matching supporting fuzzy data. A first bloom filter for a first data element is retrieved, wherein each of the characters in the data element has been encrypted with a beginning offset position of the character and encrypted with an end offset position of the character to produce two encrypted values that are added to the first bloom filter. A second bloom filter for a second data element is retrieved. The first bloom filter and the second bloom filter are compared to determine whether there is a match between the first data element and the second data element.
