BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to information sharing among network devices, and more particularly, to a method and apparatus for sharing information between network devices capable of mutually sharing various contents information among devices connected to a network.

As the smartphone's data processing capabilities and storage capacity are improved and the number of applications supported increases, many people store most of their personal data directly on their smartphones or on cloud servers.

In addition, smartphone users can view and change the necessary data anytime and anywhere by storing report data and other important data in a storage medium, a mail box, or a cloud storage medium provided in a smart phone.

In addition, as various social networking service (SNS) applications and messenger applications are installed on smartphones, work styles through existing mail are changing to faster real time interactive work styles that enable quicker information exchange and faster decision making.

Particularly, as interest in the Internet of Things (IoT) has increased recently, various application technologies for exchanging information between objects and objects equipped with various sensing means as well as exchange of information between user devices have been introduced In fact.

SKT recently launched a smart mirroring service using mirror cast dongles.

Smart Mirroring service using mirror casting dongle can connect the smart mirroring dongle to the HDMI terminal of TV, monitor, beam projector, etc., and the screen of smart phone or tablet PC is transmitted to smart mirroring dongle through WiFi communication, , A beam projector, and so on. In other words, Smart Mirroring is a kind of projector that simply moves the screen of a smartphone to a TV screen.

In addition, SKT recently introduced a smart beam service that connects a smart phone with a small beam project through a predetermined data transmission cable and outputs a screen reproduced from a smart phone through a beam project.

However, the conventional inter-device mirroring technology has a limitation in protecting privacy of an individual since mirroring is merely provided by a function of displaying a screen of a specific device mirrored equally to another device.

In addition, the conventional information sharing method has a disadvantage in that it is not possible to divide and share the detailed constituent elements constituting the contents in a manner of sharing the entire contents.

In particular, the conventional information sharing methods using mirroring have a disadvantage in that it is not possible to arbitrarily manipulate contents previously linked in a device that is provided with mirroring.
