The invention discloses a Bluetooth intelligent connection method based on cloud authorization. The method includes the steps that a Bluetooth main terminal sends an authorization request to a cloud server; the cloud sever feeds back authorization information corresponding to the Bluetooth main terminal; the Bluetooth main terminal receives the feedback on the authorization information fed back by the cloud server and obtains Bluetooth peripheral device information and access right authorization and restriction information thereof from the received authorization information; the Bluetooth main terminal is connected to a Bluetooth peripheral device in Bluetooth connection based on the obtained the Bluetooth peripheral device information. The invention further discloses a Bluetooth intelligent connection device and system based on cloud authorization. The Bluetooth connection can be established between the Bluetooth main terminal and the Bluetooth peripheral device corresponding to the Bluetooth peripheral device information included in the authorization information after the Bluetooth main terminal obtains the authorization from the cloud server, reduces the information processing such as search of another Bluetooth main terminal in the connection of a Bluetooth peripheral device and the failure of processing calling information and the interactive control on multi-media information so that the procedures that a Bluetooth main end searches for a Bluetooth peripheral device and matches the Bluetooth peripheral device during the establishment of Bluetooth connection are reduced and the problem of failure of interaction control over the processing for phone call information in calling and processing for multimedia information is solved. As a result, the connection efficiency and security of Bluetooth connection improve.
