Abstract
Embodiments include methods and systems for linking high-value tokens using a low-value token, comprising receiving, from an electronic data server, a first high-value token and a request for a low-value token, the first high-value token being associated with sensitive data associated with a user, and the low-value token being associated with a subset of the sensitive data associated with the user. The methods and systems further comprise providing the low-value token to the electronic data server, and receiving, from a second electronic data server, the low-value token and a request for a second high-value token, the low-value token having been provided to the second electronic data server by the electronic data server. The methods and systems further comprise generating a second high-value token associated with the sensitive data associated with the user, and providing the second high-value token to the second electronic data server.
