Abstract: Systems and methods for tokenization in the public cloud are disclosed. According to an embodiment, a method for tokenizing data in a public cloud may include: (1) receiving, at a tokenization service in a public cloud and from a client application, source data associated with one of a plurality of namespaces; (2) generating, by the tokenization service, a token for the source data, wherein the token has a token format that is specific to the namespace; (3) encrypting, by the tokenization service, the source data; (4) associating, by the tokenization service, the token with the encrypted source data; (5) persisting, by the tokenization service, the association between the token and the encrypted source data in a token table in the public cloud; and (6) providing, by the tokenization service, the token to the client application.
