Remote displaying

摘要

Technologies are generally described for a remote displaying scheme configured to transmit display data stored in a source device to a target device for displaying the display data on the screen of the target device. In some examples, a method performed under control of a source device may include broadcasting to one or more target devices request information that comprises a request for displaying display data, obtaining permission information generated by a target device of the one or more target devices, the permission information based, at least in part, on the request information, transmitting to the target device an acknowledgement that a communication channel between the source device and the target device is established, the acknowledgement based, at least in part, on the permission information and transmitting to the target device the display data based, at least in part, on the permission information.

主权项

1. A method, comprising:
broadcasting, by a source device, to one or more target devices request information that includes a request to display data; obtaining, by the source device, permission information generated by a target device of the one or more target devices, the permission information being based, at least in part, on the request information and a determination to permit the request to display the display data,
wherein the permission information comprises a first authentication code to access a communication network and a second authentication code to protect the display data, and the first authentication code includes a code with which the source device accesses a wireless access point and the second authentication code includes a code with which the source device encrypts the display data; transmitting, by the source device, to the target device an acknowledgement that a communication channel between the source device and the target device is established, the acknowledgement being based, at least in part, on the permission information, wherein the acknowledgement is encrypted with the first authentication code; and transmitting, by the source device to the target device, the display data to be displayed on a screen of the target device, based at least in part on the permission information, wherein the display data is encrypted with the second authentication code.
