Abstract: A method of enabling a real entity to access a service on a communication network using a virtual entity, the method including the steps of establishing a user account including at least first data corresponding to the identity of the real entity and second data corresponding to the virtual entity and not identifying the real entity, storing the first and second data in a first database, linking between the first and second data in the first database, storing the second data at a second database, associating the second database with a communication network site, connecting the communication network site to the communication network, receiving the second data from an unidentified user on the communication network site, identifying the unidentified user as the virtual entity based on receiving the second data, and allowing the virtual entity to access the service.

Abstract: Some embodiments include a virtual window system and method. In some embodiments a virtual window system may include an image capturing device to capture a high definition video image of an outdoor view and to transmit a signal corresponding to the video image; and at least one virtual window display positioned at an indoor location, to receive the signal from the image capturing device and, based on the signal, to display a high definition virtual, window-like, view corresponding to the outdoor view.

Abstract: A communication method including: modulating one more information data bits at a first site by selectively switching the path state of a first stream of photons, and demodulating said information data bits at a second site by detecting appearance and disappearance of an interference pattern of a second stream of photons correlated with said first stream of photons.
