Mirrored token vault

Abstract:

Embodiments are directed to a first token vault managed by a token service provider and a second token vault managed by a second entity. The first token vault is continuously synchronized with the second token vault in real-time. That is, the data in the second token vault is updated simultaneously with or immediately after the data in the first token vault is updated. In some embodiments, the first token vault may be a master token vault and the second token vault may be a mirror token vault. The mirror token vault may store the same information as the master token vault. Alternatively, the mirror token vault may store a subset of the information stored at the master token vault. In other embodiments, the information stored at the first token vault and the information stored at the second token vault may be mutually exclusive.
