Systems and methods that determine whether data determined by a first remote game server in association with a play of a wagering game displayed by a streaming device is authentic data. If so, the systems and methods cause a communication of the authentic data to a second remote game server operating with a client device. On the other hand, if the data is not authentic, the systems and methods store the data as unauthentic data without communicating any data to the second remote game server operating with the client device.

A software-based authentication protocol enables a client to be authenticated by a server through a host. The authentication protocol involves using mutable authentication data that changes to deter counterfeiters from making clones of authentic clients. The host requests a token from the client as proof of authenticity. The client establishes a communication channel to the server using the host as a communication proxy. The client presents mutable authentication data to the server. If the server determines that the mutable authentication data is outdated, then the client is deemed a counterfeit. If the server determined that the mutable authentication data is the latest version, then the client is deemed authentic and a token is issued to the client. Depending on a set of policies, the server changes the mutable authentication data and sends the new mutable authentication data to the client but not to counterfeit clients.
