Abstract: Disclosed is a method of providing a security service. The method is configured to include the steps of receiving a link connectable to a web page from a device of a user, connecting to a web page corresponding to the link through a remote browser and determining a risk of the connected web page, rendering a screen of the web page to be processed in the remote browser according to the determined risk, and streaming and transmitting the rendered web page screen to provide substantially the same user experience (UX) as a browser installed in the device.

Abstract: The present disclosure relates to a method for providing a device sharing service in an isolated environment, the method comprising: providing a screen of a website being accessed through a remote browser to a user device; receiving an execution request for an event capable of being provided by the user device from an operating server of the website; acquiring user data collected from the user device in response to the execution request for the event; converting the user data into remote user data for transmission to the operating server; and providing the remote user data to the operating server.

Abstract: The present disclosure relates to a method for providing a remote security service, comprising: providing a screen of a web page being accessed through a remote browser to a user device; monitoring whether an execution event for a context menu included in the web page occurs; encrypting an event constituting the context menu when the execution event occurs; generating a virtualization context menu corresponding to the encrypted event; receiving any one event which is selected from the virtualization context menu; and processing an encrypted work corresponding to the event through the remote browser, and providing the processed, encrypted work to the user device.

Abstract: A virtualization server is disclosed. The disclosed virtualization server comprises a plurality of CPUs, a plurality of GPUs, a plurality of graphic shared memories, a plurality of streaming CPUs, and a plurality of network cards, and allocates a CPU, a GPU, a graphic shared memory, a streaming CPU, and a network card to each terminal, in consideration of the number of terminals connecting to the virtualization server, the properties of applications executed by the terminals, bandwidths between the virtualization server and the terminals. Since the virtualization server can allocate a resource which matches with the performance required by each terminal, the virtualization server can be flexible to respond to an increase of the number of terminals and efficiently use resources.

Abstract: Provided is a hybrid protocol which may provide web browsing service even by means of a low-performance set-top box using a virtualization server. The virtualization server separately encodes a region of a target page, the video of the region being reproduced, or transcodes the video concerned and transmits the transcoded video. In addition, the virtualization server captures a region, on which web data is displayed, as an image file and transmits the image file to the set top box. The set top box reproduces the video using a hardware decoding chip, and restores the target page from the image file using a low-performance CPU.
