Abstract: A method of sharing Personal Identifying Information comprising; inputting one or more PII fields into a search institution to be matched; normalizing one or more fields of PII data by converting to a standard format; generating one or more fields of PII data are combined; creating a Bloom filter, Bloom filter concatenates the combined one or more fields of PII; MurmurHashing concatenated combined one or more fields of PII are multiplied by one or more constants, then rotated, then divide by thirty-two; Base64encoding, wherein each Bloom filter combinations are counted and converted to an ASCII binary format, converted combinations are divided into six characters and a decimal value; matching six characters and the decimal value are hashed with a secret key, then hash a second time with a hash function, then mix with the secret key, then hash for a third time with a hash function, then output a result.
