Claim 8:
9. A proximity based authentication system that communicates an encrypted file from a cloud component to a client device, the system comprising:
a gateway associated with a particular location that is communicatively coupled to the cloud component;
wherein the gateway includes a gateway short-range wireless radio capable of establishing a short-range wireless communication channel with the client device;
a client device communicatively coupled to the cloud component;
the client device includes a client device short-range wireless radio that communicates with the gateway using the short-range wireless communication channel when the client device is in proximity of the gateway;
the mobile device receives a gateway key over the short-range wireless communication channel, in which the mobile device communicates the gateway key to a cloud component database;
the gateway receives a mobile device key over the short-range wireless communication channel, in which the gateway communicates the mobile device key to the cloud component database;
the cloud component authenticating the particular location of the mobile device includes having the cloud component receive the gateway key from the mobile device;
the encrypted file generated from a data file by the cloud component, wherein the encrypted file is streamed to the client device;
a decryption key material generated by the cloud component, wherein the decryption key material is communicated to the gateway; and
the decryption key material is communicated from the gateway to the client device using the short-range wireless communication channel to enable the client device to decrypt the encrypted file.
