<p>A system and method provide for the selective authorization and admission of a client into a data sharing session with a host. A host may select one or more clients into the sharing session based on the proximity of the clients. When a client is selected, an identifier is provided from the client device to the host device, for example, utilizing an optical identifier such as a bar code or an audible identifier such as an encoded sound. The identifier is then utilized to establish a link between the client and the host. In this fashion any number of client devices may be selectively admitted into the sharing session in a quick and easy process enabling security for the host and anonymity for the client.</p> |
