Claim 0:
1. A method for tokenization of sensitive data, comprising:
receiving, by a tokenization computing device, sensitive data from a vendor computing device associated with a vendor;
determining, by the tokenization computing device, a token key based on the vendor associated with the sensitive data;
generating, by the tokenization computing device, a vendor-specific token associated with the sensitive data;
receiving, by the tokenization computing device, an indication of joining of the vendor with a second entity, wherein the indication includes a request to associate the vendor-specific token with a second token associated with the second entity;
generating, by the tokenization computing device, a rollup identifier that points to a common token key for the vendor and the second entity;
storing, by the tokenization computing device, the rollup identifier in a lookup table;
generating, by the tokenization computing device, a token identifier associated with the sensitive data, wherein the token identifier identifies at least one of: the token key or a sanity value;
receiving, by the tokenization computing device, a request to cancel an electronic transaction, the request including the vendor-specific token and the token identifier;
determining, by the tokenization computing device, the token key based on the token identifier;
generating, by the tokenization computing device, sensitive data associated with the electronic transaction based on the token key; and
verifying, by the tokenization computing device, an accuracy of the generated sensitive data using the token identifier.
