1. A method, comprising:
hashing, by a computing system, a first salted value to generate a first hashed salted value, the first salted value comprising a first salt value and a value;
generating, by the computing system, a first tuple, the first tuple comprising the first hashed salted value and a first token, the first token associated with the value; and
generating, by the computing system, a first blockchain anonymous tokenization message, the first blockchain anonymous tokenization message comprising the first salt value, wherein the first blockchain anonymous tokenization message is associated with the first tuple,
wherein the first blockchain anonymous tokenization message provides third party anonymity and is accessible through a first linkage posted on a blockchain,
wherein verification of data integrity of the first tuple is determined by retrieving the first salt value in the first blockchain anonymous tokenization message and detokenizing the first token to retrieve a detokenized value.
