11 Claims

1. A method for performing a secure data transfer between computing devices, comprising:

registering a resource-constrained computing device with a cloud-based computer;

generating, by a client computing device, session state information regarding the client computing device in an electronic communication exchange with at least one remote computing device;

storing the session state information at the cloud-based computer;

generating an identifier that provides a location of the session state information stored at the cloud-based computer;

displaying a machine-readable code associated with the identifier for querying the cloud-based computer for the stored session state information;

processing, by the resource-constrained computing device, the machine-readable code to retrieve the session state information from the cloud-based computer; and

processing, by the resource-constrained computing device, the session state information to integrate the resource-constrained computing device with the client computing device to participate in the electronic communication exchange with the at least one remote computing device, the method further comprising:

determining a client-side change in the session state information;

sending a refresh state of the session state information including the client-side change to the cloud-based computer;

storing at the cloud-based computer the refresh state of the session state information;

providing the stored refresh state of the session state information a key value including a unique index generated by the cloud-based computer in response to a request by the stationary computing device to store the stored refresh state of the session state information; and

displaying the machine-readable code as a visual representation of the key value.
