[0049] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0050] The visual Internet is an important milestone in the development of the Internet. It is a real-time network that can realize real-time transmission of high-definition video and push many Internet applications towards high-definition video and high-definition face-to-face communication.

[0051] The visual network adopts real-time high-definition video exchange technology. It can integrate the required services such as high-definition video conferencing, video monitoring, intelligent monitoring analysis, emergency command, digital radio and television, delayed TV, online teaching, live broadcast, VOD on demand, TV mail, personalized recording (PVR), intranet (self-operated) channels, intelligent video broadcast control, information release and dozens of other video, voice, picture, text, communication, data and other services on a single system platform, and realize high-definition quality video playback through TV or computer.

[0052] Based on the above-mentioned characteristics of the visual network, one of the core concepts of an embodiment of the present invention is proposed, which follows the protocol of the visual network and receives a watermark acquisition request sent by a visual network terminal, wherein the watermark acquisition request includes a target security transmission identifier and a target terminal identifier of the visual network terminal, and the security transmission identifier is determined based on the configuration information of the visual network terminal; based on the target terminal identifier of the visual network terminal, a preset security transmission identifier corresponding to the target terminal identifier is searched in a pre-established security database, wherein the security database includes the correspondence between the terminal identifier of the visual network terminal and the security transmission identifier; if the target security transmission identifier is the same as the preset security transmission identifier, then the watermark information is sent to the visual network terminal corresponding to the target security transmission identifier. In this way, the security of the watermark transmission is improved by judging the security transmission identifier in the watermark acquisition request.

[0053] The glossary is explained as follows:

[0054] 1. Watermark: semi-transparent text, icons, logos, etc. In this patent, it refers to pictures with the above content.

[0055] 2. Conference control software: video network conference control software, used to control video network terminal conferences, with functions such as scheduling conferences, controlling conferences, setting terminal parameters, conference recording, etc. In the embodiment of the present invention, it is Pamir software.

[0056] 3. Layer: Since the visual networking hardware terminal is an embedded terminal, based on hardware support, multiple layers can be implemented in the terminal's graphics display processing mechanism, and each layer can realize specific functions.

[0057] 4. Token: Token is a string of characters generated by the server, which is used as a token when the client requests the server. When the client connects to the server for the first time, the server generates a token and returns it to the client. In the future, the client only needs to bring this token to request data, without having to bring the username and password again. Adding the token mechanism can ensure the security of watermark information transmission and reduce the security verification pressure on the server.

[0058] 5. Network path: As long as each terminal is registered on the visual network, according to the location of the core server, the terminal must have a network path to the core server. The path includes the switches and ports (and other network devices along the way). This path is called the terminal's network path.

[0059] An embodiment of the present invention provides a watermark acquisition method for acquiring watermark information. The execution subject of this embodiment is a watermark acquisition device, which is arranged on a conference control device, wherein the conference control device can be a computer, a tablet computer, a mobile phone terminal, etc.

[0060] Reference Figure 1 , shows a flow chart of steps of an embodiment of a watermark acquisition method of the present invention, the method may specifically include the following steps:

[0061] S101, receiving a watermark acquisition request sent by a visual networking terminal, wherein the watermark acquisition request includes a target secure transmission identifier and a target terminal identifier of the visual networking terminal, and the secure transmission identifier is determined according to configuration information of the visual networking terminal;

[0062] Specifically, conference control software is installed on the conference control terminal, which is connected to the network management server and to the visual network terminal. The conference control terminal adds the visual network terminal to the conference through the conference control software. At this time, the visual network terminal becomes a participant terminal. If you want to add watermark information to the display data on the visual network terminal, the visual network terminal actively sends a watermark acquisition request to the conference control terminal. The watermark acquisition request includes the destination mac address, source mac address, IP header, TCP header, secure transmission identifier and data content, where the secure transmission identifier is Token.

[0063] Specifically, the security transmission identifier in the watermark acquisition request sent by the visual network terminal may be an empty byte, a correct string, or an incorrect string. If it is a correct security transmission identifier, the security transmission identifier is determined based on the configuration information of the visual network terminal. The configuration information includes at least the visual network number, MAC address, terminal factory serial number, network path, etc., wherein the network path specifically means that as long as each terminal is registered on the visual network, according to the location of the core server, the terminal must have a network path to the core server, and the path includes switches and ports passed through, as well as other network devices along the way.

[0064] S102, according to the target terminal identifier of the visual network terminal, searching a pre-established security database for a preset security transmission identifier corresponding to the target terminal identifier, wherein the security database includes a correspondence between the terminal identifier of the visual network terminal and the security transmission identifier;

[0065] Specifically, a security database is pre-established on the conference control terminal, wherein the security database includes the correspondence between the terminal identification of the visual network terminal and the security transmission identification, wherein the terminal identification of the visual network terminal can be the visual network number or the MAC address of the visual network terminal, and the security transmission identification is Token, wherein Token is a string of characters generated by the server, which serves as a token when the client requests the server. When the client connects to the server for the first time, the server generates a Token and returns it to the client. In the future, the client only needs to bring this Token to request data without bringing the username and password again. Adding the Token mechanism can ensure the security of watermark information transmission and reduce the security verification pressure on the server. The server is the conference control terminal and the client is the visual network terminal.

[0066] When the conference control terminal receives the watermark acquisition request sent by the visual network terminal, it parses the watermark acquisition request to obtain the target security transmission identifier and the target terminal identifier, and searches the pre-established security database for the preset security transmission identifier corresponding to the target terminal identifier based on the target terminal identifier.

[0067] S103. If the target secure transmission identifier is the same as the preset secure transmission identifier, watermark information is sent to the visual network terminal corresponding to the target secure transmission identifier.

[0068] Specifically, the conference control terminal judges the target security transmission identifier and the preset security transmission identifier. If the two are the same, the watermark information is sent to the visual network terminal corresponding to the target security transmission identifier; if the two are different, the watermark information is not sent to the visual network terminal corresponding to the target security transmission identifier. In this way, the security of watermark transmission is improved by judging the security transmission identifier in the watermark acquisition request.

[0069] The watermark acquisition method provided by the embodiment of the present invention receives a watermark acquisition request sent by a visual network terminal, wherein the watermark acquisition request includes a target security transmission identifier and a target terminal identifier of the visual network terminal, and the security transmission identifier is determined based on the configuration information of the visual network terminal; based on the target terminal identifier of the visual network terminal, a preset security transmission identifier corresponding to the target terminal identifier is searched in a pre-established security database, wherein the security database includes the correspondence between the terminal identifier of the visual network terminal and the security transmission identifier; if the target security transmission identifier is the same as the preset security transmission identifier, watermark information is sent to the visual network terminal corresponding to the target security transmission identifier. In this way, the security of watermark transmission is improved by judging the security transmission identifier in the watermark acquisition request.

[0070] Another embodiment of the present invention further supplements the watermark acquisition method provided in the above embodiment.

[0071] like Figure 2 FIG. 1 is a flowchart showing another watermark acquisition method embodiment of the present invention, wherein the watermark acquisition method comprises:

[0072] S201, sending a joining instruction to the video network terminal;

[0073] Specifically, the conference control device is installed with conference control software, and the conference joining instruction is sent to the video network terminal through the conference control software;

[0074] S202, receiving a successful joining response returned by the video networking terminal;

[0075] Specifically, each video networking terminal returns a successful joining response to the conference control device.

[0076] S203, receiving a watermark acquisition request sent by a visual networking terminal, wherein the watermark acquisition request includes a target terminal identifier of the visual networking terminal;

[0077] Specifically, the security transmission identifier in the watermark acquisition request sent by the visual network terminal may be an empty byte, a correct string, or an incorrect string. If it is a correct security transmission identifier, the security transmission identifier is determined based on the configuration information of the visual network terminal. The configuration information includes at least the visual network number, MAC address, network path, etc., wherein the network path specifically means that as long as each terminal is registered on the visual network, according to the location of the core server, the terminal must have a network path to the core server, and the path includes switches and ports passed through, as well as other network devices along the way.

[0078] S204, searching a pre-established security database for a preset security transmission identifier corresponding to the target terminal identifier according to the target terminal identifier of the visual network terminal;

[0079] S205. If a target security transmission identifier corresponding to the target terminal identifier is found in the pre-established security database, and the target security transmission identifier is the same as the preset security transmission identifier, watermark information is sent to the visual network terminal corresponding to the target security transmission identifier.

[0080] S206, if the security transmission identifier corresponding to the target terminal identifier is not found in the pre-established security database, sending a request for obtaining configuration information of the visual network terminal to the network management server, wherein the request for obtaining configuration information includes the target terminal identifier of the visual network terminal;

[0081] Specifically, if the conference control terminal fails to find the security transmission identifier corresponding to the target terminal identifier in the pre-established security database, that is, the security transmission identifier is an empty byte, it is necessary to send a request to obtain the visual network terminal configuration information to the network management server, wherein the request to obtain the configuration information includes the target terminal identifier of the visual network terminal, such as the visual network number, the visual network MAC address, etc.

[0082] S207, receiving configuration information of the visual network terminal corresponding to the target terminal identifier returned by the network management server, wherein the configuration information includes one or more of the MAC address of the visual network terminal, the visual network number, the terminal factory serial number and the network path;

[0083] S208, determining a secure transmission identifier corresponding to the visual networking terminal according to the configuration information of the visual networking terminal;

[0084] Specifically, a message digest algorithm is used for the configuration information of the visual networking terminal to obtain a secure transmission identifier corresponding to the visual networking terminal.

[0085] The conference control terminal performs MD5 operation on the configuration information of the visual network terminal, such as one or more of the visual network terminal MAC address, visual network number, terminal factory serial number and network path, to obtain a secure transmission identifier corresponding to the visual network terminal.

[0086] Message Digest Algorithm: MD5, the fifth version of the message digest algorithm, is a hash function widely used in the field of computer security to provide message integrity protection. MD5 is Message-Digest Algorithm 5, which is used to ensure the integrity and consistency of information transmission. It is one of the hash algorithms widely used in computers, and is also a digest algorithm and hash algorithm. The basic principle of the hash algorithm is to calculate data into another fixed length value.

[0087] The MD5 algorithm has the following characteristics:

[0088] 1. Compression: For data of any length, the length of the calculated MD5 value is fixed.

[0089] 2. Easy to calculate: It is easy to calculate the MD5 value from the original data.

[0090] 3. Anti-modification: Any changes to the original data, even if only one byte is modified, will result in a significant difference in the resulting MD5 value.

[0091] 4. Strong anti-collision: If the original data and its MD5 value are known, it is very difficult to find data with the same MD5 value (i.e. forged data).

[0092] The function of MD5 is to "compress" large amounts of information into a confidential format before signing a private key with digital signature software. That is, it converts a byte string of arbitrary length into a hexadecimal digit string of a certain length.

[0093] In the embodiment of the present invention, in addition to MD5, sha-1, RIPEMD and Haval can also be used to determine the secure transmission identifier;

[0094] SHA (Secure Hash Algorithm);

[0095] RIPEMD (RACE Integrity Primitives Evaluation Message Digest)

[0096] Haval: The HAVAL encryption algorithm can generate hash values ​​of different lengths, including 128 bits, 160 bits, 192 bits, 224 bits, and 256 bits. You can also specify the number of rounds (3, 4, or 5) to generate the hash calculation.

[0097] S209: If the watermark information changes, send a watermark change instruction to the visual networking terminal, so that the visual networking terminal sends the watermark acquisition request again after receiving the watermark change instruction.

[0098] Specifically, if the watermark information needs to be updated during the meeting, pamir first sends a watermark update notification. After receiving the notification, the terminal re-requests the watermark, and the watermark can be obtained by repeating the above operations.

[0099] Since steps S202 to S204 are Figure 1 Steps S101 and S103 in the illustrated embodiment are identical. Figure 1 Steps S101 to S103 have been described in detail in the specification, so steps S202 to S204 will not be described again here.

[0100] Figure 3 is a structural block diagram of an embodiment of a watermark acquisition system of the present invention, such as Figure 3 As shown, it includes a conference control terminal, on which conference control software is installed. The conference control terminal is connected to the network management server, the visual network core server, and the visual network terminal through a switch. The conference control terminal adds the visual network terminal to the conference through the conference control software.

[0101] Figure 4 is a flow chart of steps of another watermark acquisition method embodiment of the present invention, such as Figure 4 As shown, the watermark acquisition method includes:

[0102] 1. The conference control terminal starts the conference through the pamir software and joins the conference through the network terminal;

[0103] 2. The visual network terminal actively starts to request watermarks and sends out a request packet. Since it is the first time to send a packet, the token information reserved in the packet header is an empty byte;

[0104] 3. After receiving the request, the conference control terminal checks that the packet header does not contain token information, queries the local database, and finds that this is the first time the terminal has requested a watermark;

[0105] 4. The conference control terminal connects to the OMC network management server and sends a configuration information query command of the terminal to the OMC network management server. The configuration information includes: terminal SN (i.e., terminal factory serial number), network path, GPS location, etc.

[0106] 5. The conference control terminal synchronizes the terminal configuration information to the local database, and generates a token, i.e., a secure transmission identifier, based on the configuration information of each terminal, i.e., user number, MAC address, network path, etc., which is also stored in the local database.

[0107] 6. After receiving the first request information, the conference control terminal searches the database for the token of the terminal and sends the token to the terminal;

[0108] 7. After receiving the token sent by the conference control terminal, the terminal first stores the token in the local configuration file and sends a watermark request again. The difference from the last time is that the token byte is added to the request header this time.

[0109] 8. The conference control terminal receives the request message containing the token and queries the local database to verify whether the token is consistent.

[0110] 9. After the conference control terminal verifies the token, it sends the watermark information to the terminal;

[0111] 10. The terminal receives the watermark and opens it in the watermark layer;

[0112] 11. Watermark acquisition is completed;

[0113] 12. If the watermark information needs to be updated during the meeting, the conference control terminal will first send a watermark update notification. After receiving the notification, the terminal will re-request the watermark. Repeat the above operations to obtain the watermark.

In this way, the security of watermark transmission is improved by judging the security transmission identifier in the watermark acquisition request.
