Detailed Description

For the convenience of understanding of the embodiments of the present invention, the following description will be further explained with reference to specific embodiments, which are not to be construed as limiting the embodiments of the present invention.

According to the interconnection method, the interconnection device and the interconnection terminal based on the multiple terminals, the user identity is verified through the user identity identification, the connection process of the multiple terminals is simplified, the steps of searching an IP address of a target terminal (equivalent to a second terminal) by a user, manually inputting the IP address and a password and the like are omitted, and the user can realize automatic interconnection among the multiple terminals only by sending a connection request and an authentication process.

Fig. 1 is an interaction diagram for implementing terminal interconnection by the lan technology. As shown in fig. 1, the terminal B receives a data command input by a user, and the data command includes: the IP address or username and password of terminal a (i.e., the second terminal to which terminal B wants to connect); and the terminal B sends request information to the terminal A according to the data instruction. The terminal A sends authentication information to the terminal B according to the request information. The terminal B prompts a user to input authentication information, determines a feedback authentication information instruction, responds to the instruction, carries the feedback authentication information to connect with the terminal A, authenticates the terminal A with the authentication information stored in the terminal according to the feedback authentication information sent by the terminal B, allows the terminal A to establish connection with the terminal B after the authentication is passed, and successfully connects with the terminal A.

At present, the steps of establishing the connection in the above method are relatively complicated, and a user needs to first determine an IP address or a user name and a password of a terminal a (i.e., a second terminal) in a network connection manner, and it is difficult to interconnect with the second terminal when the IP address or the user name and the password of the terminal a are unclear. In addition, the above method is complex in the connection process, and requires the user to determine and input the IP address of the second terminal, and then input the authentication information, which results in a more complex interconnection process between the terminal a and the terminal B and a longer connection time.

Fig. 2 is a schematic diagram of an architecture based on interconnection of multiple terminals according to an embodiment of the present invention. As shown in fig. 2, in response to the problem shown in fig. 1, fig. 2 shows a method for rapidly interconnecting a plurality of terminals in the same lan. It should be noted that the following second terminals may be multiple, specifically, the terminal a (i.e., the first terminal), the terminal B (i.e., the second terminal), and the terminal C (i.e., the second terminal) are in the same local area network, and the terminal a is connected to at least one of the terminal B and the terminal C by a fast connection, so as to realize fast data sharing and remote control on terminals of different types or models. The terminal a only needs to broadcast a first message, where the first message may include first matching information and an address of the terminal a, and the first matching information is used to match at least one of the terminal B and the terminal C (i.e., a second terminal) in the same local area network; at least one of the terminal B and the terminal C receives the first message, and sends a second message according to the address of the terminal a in the first message, where the second message may include: an address of at least one of terminal B and terminal C. And when the verification is successful and the connection with the terminal A is allowed, at least one of the terminal B and the terminal C sends a third message to the terminal A, and the third message is used for indicating the successful verification and allowing the connection, so that the interconnection of a plurality of terminals is realized.

It should be noted that the terminals in the same lan as the terminal a may include a plurality of terminals, and one or more terminals may be interconnected with the terminal a. The above-mentioned sending involving the first message, the second message and the user identity may be forwarding the respective messages by local area network connection terminals (e.g. routers and switches). The terminal (e.g., terminal A, B, C or D) may be a mobile phone, a tablet computer, a notebook computer, a Personal Digital Assistant (PDA), a point of sale (POS), a camera, a video camera, a car-mounted computer, or the like. And the involved terminals may be connected to each other.

The method provided by the embodiment of the invention can also be applied to the situation that when the terminal A and a plurality of terminals are in the same local area network, the terminal A is purposefully connected with the terminal B, and when the terminal A receives second messages sent by the plurality of terminals, the terminal A can selectively send the user identity identifier in the terminal A, namely only the user identity identifier in the terminal A is selectively sent to the terminal B.

The display unit 140 may include a display panel 141, wherein the display panel 141 may be configured in the form of an LCD (liquid crystal display), an OLED (organic light-emitting diode), or the like. Further, the touch panel 131 can cover the display panel 141, and when the touch panel 131 detects a touch operation on or near the touch panel 131, the touch operation is transmitted to the processor 180 to determine the type of the touch event, and then the processor 180 provides a corresponding visual output on the display panel 141 according to the type of the touch event. Although in fig. 3, the touch panel 131 and the display panel 141 are two independent components to implement the input and output functions of the mobile phone 100, in some embodiments, the touch panel 131 and the display panel 141 may be integrated to implement the input and output functions of the mobile phone 100.

Fig. 4 is an interaction diagram based on interconnection of multiple terminals according to an embodiment of the present invention. As shown in fig. 4, the interaction method based on interconnection of multiple terminals may specifically include S410-S480, as follows:

s410: the first terminal broadcasts a first message.

Specifically, in the same local area network, a first terminal broadcasts a first message through a User Datagram Protocol (UDP), where the first message is used to inquire whether a second terminal meeting a certain condition in the same local area network can connect. The first packet may be transmitted through a network socket (socket) interface, where the socket is an interface for Transmission Control Protocol (TCP) and UDP programming. The first packet may specifically include: first matching information and an address of a first terminal, the first matching information being used for matching a second terminal in the same local area network, wherein the first matching information may include: at least one of an Identification (ID) of the first terminal, a device type of the first terminal, a port number of the first terminal, a time of requesting a connection, a terminal type of allowing a connection to be established, and an allowed timeout time.

It should be noted that the ID of the first terminal, the device type of the first terminal, and the port number of the first terminal are used for the second terminal to determine the identity information of the first terminal; the terminal type allowing connection establishment is used for the first terminal to designate a matched second terminal in the same local area network, namely, the terminal type can be understood as directional interconnection with the second terminal meeting the condition; the allowed timeout is used to determine the timeliness of the connection established between the first terminal and the second terminal.

S420: the second terminal receives the first message broadcast by the first terminal and judges whether to establish connection with the first terminal according to the first message.

Specifically, the second terminal may determine whether to establish a connection with the first terminal according to the type of the terminal in the first message, where the connection is allowed to be established; or, the second terminal may determine whether to establish a connection with the first terminal according to at least one of the ID of the first terminal, the port number of the first terminal, and the address of the first terminal in the first message.

And when the second terminal determines that the connection with the first terminal is not established according to the first message, abandoning the first message and ending the process.

And executing S430 when the second terminal determines to establish connection with the first terminal according to the first message.

S430: the second terminal obtains a second message, where the second message may include: the address of the second terminal is associated with at least one of an ID of the second terminal, a device type of the second terminal, a port number of the second terminal, a time when the connection is requested, a type of terminal allowed to establish the connection, and an allowed timeout time.

S440: and the second terminal sends a second message to the first terminal by using a socket interface through UDP unicast.

S450: the first terminal extracts fingerprint abstract information of the user.

Specifically, the step may include: the first terminal collects and stores fingerprint information of a user in advance, and determines fingerprint abstract information of the user according to the fingerprint information (the step of determining the fingerprint abstract information is described in detail in fig. 5); or the first terminal prompts the user to collect the fingerprint in real time and determines the abstract information of the fingerprint.

It should be noted that the fingerprint digest information of the user is only one of the user identification, and the user identification may also be iris digest information and password information.

It should be noted that the step may be performed after receiving the second message, or the first terminal may perform the step after performing S420.

S460: and the first terminal sends a user identity identifier to the second terminal through UDP unicast according to the address of the second terminal in the second message, wherein the user identity identifier is used for the second terminal to verify the first terminal.

Specifically, the first terminal further sends a user identity according to at least one of an ID of the second terminal, a device type of the second terminal, and a port number of the second terminal in the second message, where the user identity may include: fingerprint summary information.
