Tokenizing sensitive data

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;
• generating, by the tokenization computing device, a vendor-specific token that is associated with the sensitive data;
• receiving, by the tokenization computing device, a request to change the vendor-specific token;
• generating, by the tokenization computing device, a new token for associating with the sensitive data;
• and
• sending, by the tokenization computing device, a token identifier and the new token to the vendor computing device, wherein the token identifier is configured to provide token generation data and a sanity value.

A system for tokenization of sensitive data, comprising:

• a processor;
• and
• a memory component that is coupled to the computing device and stores logic that when executed by the processor, causes the system to perform at least the following:
• receive, from a vendor computing device, a request to change a vendor-specific token that is associated with sensitive data, wherein the vendor computing device is associated with a vendor, wherein the request is accompanied by a token identifier that is associated with the vendor-specific token, and wherein the vendor-specific token and the token identifier are linked in a database, wherein the token identifier is configured to provide token generation data and a sanity value;
• utilize the token identifier to determine a location of the sensitive data;
• retrieve the sensitive data;
• generate a new token for associating with the sensitive data;
• and
• send the new token and the token identifier to the vendor computing device.

A non-transitory computer-readable medium for tokenization of sensitive data that stores a program that when executed by a computing device, causes the computing device to perform at least the following:

• receive a request to change a token that is associated with sensitive data, wherein the token is generated based at least in part on a token key that is unique to a vendor, wherein the request is accompanied by a token identifier that is associated with the token, and wherein the token and the token identifier are linked in a database, and the token identifier is configured to provide token generation data and a sanity value;
• identify the token key and a version for the token from the token identifier;
• generate a new token for associating with the sensitive data;
• and
• send the new token and the token identifier to a vendor computing device.
