Proximity based authentication system and method

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.

A proximity based authentication method for communicating an encrypted file from a cloud component to a client device, the method comprising:

• associating a gateway with a particular location;
• communicatively coupling the gateway to the cloud component, wherein the gateway includes a gateway short-range wireless radio;
• establishing, by the gateway, a short-range wireless communication channel with the client device;
• communicatively coupling the client device to the cloud component, wherein the client device includes a client device short-range wireless radio;
• communicating, by the client device short-range wireless radio over the short-range wireless communication channel, with the gateway when the mobile device is in proximity of the gateway;
• receiving, at the client device, a gateway authentication key over the short-range wireless communication channel, in which the client device communicates the gateway authentication key to a cloud component database;
• receiving, at the gateway, a client authentication device key over the short-range wireless communication channel, in which the gateway communicates the client authentication device key to the cloud component database;
• authenticating, at the cloud component, the particular location of the client device when the cloud component receives the gateway authentication key from the client device;
• receiving, at the client device, the gateway authentication key over the short-range wireless communication channel the client device communicates the gateway authentication key to the cloud component database;
• generating, by the cloud component, the encrypted file from a data file;
• communicating, by the cloud component, the encrypted file to the client device;
• generating, by the cloud component, a decryption key material;
• communicating, by the cloud component, the decryption key material to the gateway;
• and
• communicating, by the gateway short-range wireless radio, the decryption key material to the client device over the short-range wireless communication channel to enable the client device to decrypt the encrypted file.
