Problems solved by technology

Since there are no filtering rules, any USB device may be redirected to the cloud desktop. In this way, for some human-computer interaction devices (Human Interface Devices) such as keyboards, mice, or USB wireless network cards, these should be used as the USB interface of the client device. The device is also redirected to the cloud desktop, causing these USB devices to not work properly

Abstract

The invention discloses a USB redirection filtering method based on a cloud desktop. The method comprises the following steps: 1) configuring a USB redirection filtering rule at a client; 2) the client identifying the accessed USB equipment and acquiring USB equipment information; wherein the USB equipment information comprises a USB equipment type, a manufacturer identifier, a product identifierand a product description; 3) the client program performing rule comparison according to the configured USB filtering rule and the accessed USB equipment information; 4) if the USB equipment meets thepermission rule, allowing the USB equipment to be redirected to the cloud desktop, and 5) for the USB equipment allowed to be redirected, the client supporting the user to select redirection to the cloud desktop or uninstalling the local equipment serving as the client from the cloud desktop after selection is canceled according to the selection of the user. According to the method, the USB equipment redirected to the cloud desktop can be accurately controlled, and a redirection filtering function is provided for all the USB equipment.

Description

technical field [0001] The invention relates to cloud platform technology, in particular to a cloud desktop-based USB redirection filtering method. Background technique [0002] The cloud desktop allows the client to redirect the USB device to the cloud desktop. When the client program accesses the USB device, the client recognizes the USB device and can redirect the USB device to the cloud desktop. Since there are no filtering rules, any USB device may be redirected to the cloud desktop. In this way, for some human-computer interaction devices (Human Interface Devices) such as keyboards, mice, or USB wireless network cards, these should be used as the USB interface of the client device. Devices are also redirected to Cloud Desktop, causing these USB devices not to work properly. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a cloud desktop-based USB redirection filtering method for the defects in the prior ar...
