[0064] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0065] The Visual Networking is an important milestone in the development of the network. It is a real-time network that can achieve real-time transmission of high-definition video, pushing many Internet applications towards high-definition video and high-definition face-to-face.

[0066] The Visual Networking adopts real-time high-definition video exchange technology, and can integrate dozens of services such as high-definition video conferencing, video surveillance, intelligent surveillance analysis, emergency command, digital radio and television, delayed television, online teaching, live broadcast, VOD on demand, TV mail, personal recording (PVR), internal network (self-run) channels, intelligent video broadcast control, information release, etc., including video, voice, pictures, text, communication, data, etc. on a network platform, and realizes high-definition quality video playback through a TV or a computer.

[0067] An embodiment of the present invention provides a data communication method for data communication between service servers. The execution subject of this embodiment is a data communication device, which is set on a signaling server in a Visual Networking data communication system.

[0068] Referring to Figure 1 , a step flow chart of an embodiment of a data communication method of the present invention is shown. This method can be applied to a signaling server in a Visual Networking data communication system. The signaling server and multiple service servers are pre-connected. The service servers include a service server at the sending end and a service server at the receiving end. Specifically, it can include the following steps:

[0069] S101. Send a request instruction for communication information to the service server at the receiving end, where the request instruction is sent by the service server at the sending end;

[0070] Specifically, when the service server at the sending end wants to communicate with the service server at the receiving end, for example, to conduct a certain service such as a video phone call, a video conference, a live broadcast, etc., the service server at the sending end needs to know the communication information of the service server at the receiving end in order to communicate with the service server at the receiving end. An embodiment of the present invention provides a signaling server that forwards the communication information of each service server. In actual operation, the service server at the sending end sends a request instruction for communication information to the signaling server. The request instruction includes the communication information of the service server at the sending end. The communication information of the service server at the sending end includes the first transmission protocol type, the first communication address, the first relay server address, etc. The signaling server sends the request instruction to each of the other service servers, that is, the service server at the receiving end.

[0071] Among them, the communication address is the Visual Networking number or IP number of the service server and the corresponding port number.

[0072] S102. Receive a response instruction returned by the service server at the receiving end, where the response instruction includes the communication information of the service server at the receiving end;

[0073] Specifically, after receiving the request instruction sent by the signaling server, the service server at the receiving end returns a response instruction to the signaling server and loads its own communication information in the response instruction and sends it to the signaling server.

[0074] S103. Send the communication information of the service server at the receiving end to the service server at the sending end, so that the service server at the sending end establishes a connection with the service server at the receiving end according to the communication information of the service server at the receiving end and conducts data communication with the service server at the receiving end according to the established connection.

[0075] Specifically, after receiving the communication information sent by multiple service servers at the receiving end, the signaling server sends the communication information of the multiple service servers at the receiving end to the service server at the sending end. The service server at the sending end parses the communication information of the service server at the receiving end, obtains the communication information of the service server at the receiving end, and establishes a connection with the corresponding service server at the receiving end according to the communication information and conducts data communication with the service server at the receiving end according to the established connection.

[0076] Exemplarily, the signaling server is respectively connected to service servers A, B, C, D, and E. The service server A sends a request instruction for communication information to the signaling server, and the signaling server sends the request instruction to service servers B, C, D, and E, and receives the communication information returned by each of service servers B, C, D, and E. The service server A establishes connections with the corresponding other servers, such as service servers B, C, D, and E, according to the communication information, and performs data communication based on the established connections.

[0077] The data communication method provided by the embodiment of the present invention sends a request instruction for communication information to the service server at the receiving end through the signaling server, where the request instruction is sent by the service server at the sending end; receives the response instruction returned by the service server at the receiving end, and the response instruction includes the communication information of the service server at the receiving end; sends the communication information of the service server at the receiving end to the service server at the sending end, so that the service server at the sending end establishes a connection with the service server at the receiving end according to the communication information of the service server at the receiving end, and performs data communication with the service server at the receiving end based on the established connection. In this way, the service server sends its own communication information to the signaling server by sending a request instruction for communication information to the signaling server, and at the same time receives the communication information of other service servers returned by the signaling server, and the service servers can perform data communication through the communication information, improving the communication efficiency.

[0078] Another embodiment of the present invention further supplements and explains the data communication method provided in the above embodiment.

[0079] As Figure 2 shown, a step flowchart of another embodiment of the data communication method of the present invention is shown. This method can be applied to a signaling server in a visual networking data communication system. The signaling server and multiple service servers are pre-connected. The service servers include a service server at the sending end and a service server at the receiving end. The data communication method includes:

[0080] S201. Receive the login request of the service server at the sending end. The login request includes login information, and the login information includes a preset MAC address, a preset user name, and a preset login password of the service server at the sending end;

[0081] Specifically, the embodiment of the present invention provides a signaling server, which is specifically used to forward signaling. The signaling types include request signaling, response signaling, and transit signaling.

[0082] The service server at the sending end needs to be authenticated on the signaling server first. The service server at the sending end sends a login request to the signaling server. The login request includes a login request, which includes the preset MAC (Media Access Control or Medium Access Control) address of the service server at the sending end. MAC address is also known as the physical address or hardware address, which is used to define the location of network devices), a preset username, and a preset login password.

[0083] S202. According to the preset encryption method, perform encryption calculation on the preset MAC address, preset username, and preset login password of the service server at the sending end to obtain the verification identifier of the service server at the sending end, where the verification identifier includes a preset encryption method identifier;

[0084] Specifically, the preset encryption methods include Base64 encryption method, MD5 encryption, keychain encryption, symmetric encryption algorithm, RSA encryption, etc. These are not specifically limited in the embodiments of the present invention. No matter which encryption method is used, the encryption method identifier needs to be put into the verification identifier so that the service server at the sending end can decrypt according to the decryption method corresponding to the encryption method identifier.

[0085] Exemplarily, the following are the various encryption methods, and the corresponding encryption method can be selected according to actual needs:

[0086] 1. Base64 encryption method (reversible)

[0087] The printable characters in Base64 include letters A-Z / a-z / numbers 0-9 / plus sign ‘+’ and slash ‘ / ’, so there are a total of 62 characters;

[0088] Base64 was added to the system library after iOS7.

[0089] 2. MD5 encryption method

[0090] Message Digest Algorithm MD5 (Chinese name: Message Digest Algorithm Fifth Edition) is a hash function used to provide integrity protection for messages. It is also translated as the digest algorithm or hash algorithm. According to the output value, the original plaintext cannot be obtained, that is, the process is irreversible.

[0091] The MD5 algorithm has the following characteristics:

[0092] 1) Compressibility: For data of any length, the length of the calculated MD5 value is fixed.

[0093] 2) Easy to calculate: It is very easy to calculate the MD5 value from the original data.

[0094] 3) Anti-modification: Any modification to the original data, even if only 1 byte is changed, will result in a significant difference in the obtained MD5 value.

[0095] 4) Strong anti-collision: Given the original data and its MD5 value, it is very difficult to find a data with the same MD5 value (i.e., forged data).

[0096] The role of MD5 is to "compress" large-capacity information into a confidential format before signing the private key with digital signature software (that is, to transform a byte string of any length into a hexadecimal digital string of a certain length). In addition to MD5, the more well-known ones are sha-1, RIPEMD, as well as Haval, MD5 with salt, etc.

[0097] 3. Keychain encryption method

[0098] iCloud Keychain, a kind of sandbox:

[0099] 1) If the mobile phone is jailbroken, the password is easily stolen.

[0100] 2) When the software is updated, the content in the sandbox is not deleted. However, if the software is uninstalled and reinstalled, the data in the sandbox will be gone.

[0101] 3) The sandbox of each APP is relatively independent, and passwords cannot be shared.

[0102] 4. Symmetric encryption algorithm

[0103] Advantages: The algorithm is public, the calculation amount is small, the encryption speed is fast, the encryption efficiency is high, and it is reversible;

[0104] Disadvantages: Both parties use the same key, and the security cannot be guaranteed

[0105] Current situation: The speed of symmetric encryption is much faster than that of public key encryption, and symmetric encryption is required in many occasions.

[0106] Algorithms: Commonly used algorithms in symmetric encryption algorithms include: DES, 3DES, TDEA, Blowfish, RC2, RC4, RC5, IDEA, SKIPJACK, AES, etc. The implementation mechanisms of different algorithms are different, and the detailed information of the corresponding algorithms can be referred to.

[0107] Compared with DES and 3DES algorithms, the AES algorithm has higher speed and resource utilization efficiency, and the security level is also higher, and it is called the next-generation encryption standard.

[0108] nECB: Electronic Codebook, that is, each block is encrypted independently;

[0109] nCBC: Cipher Block Chaining, which performs an encryption transformation on data using a key and an initialization vector (IV).

[0110] Differences between ECB and CBC: CBC is more complex and secure, with an 8-bit vector added (if it's all 8 zeros, the result is equal to ECB). If you change a single letter in the plaintext, the corresponding line in the ECB ciphertext will change, while in the CBC ciphertext, all lines from that point onwards will change.

[0111] 5. RSA Encryption (Asymmetric Encryption Algorithm) (Secruty.framework system library)

[0112] Asymmetric encryption algorithms require two keys: a public key and a private key.

[0113] The main algorithms used in asymmetric encryption are: RSA, Elgamal, Knapsack algorithm, Rabin, D-H, ECC (Elliptic Curve Cryptography), etc.

[0114] The public key and the private key are a pair. If data is encrypted with the public key, only the corresponding private key can decrypt it; if data is encrypted with the private key, then only the corresponding public key can decrypt it.

[0115] Features:

[0116] Features of the asymmetric cryptosystem: The algorithm strength is complex, and the security depends on the algorithm and the key. However, due to its complex algorithm, the encryption and decryption speed is not as fast as that of symmetric encryption and decryption.

[0117] In the symmetric cryptosystem, there is only one key, which is not public. If you want to decrypt, you have to let the other party know the key. So ensuring its security is to ensure the security of the key. In contrast, the asymmetric key cryptosystem has two keys, one of which is public, so there is no need to transmit the other party's key like in symmetric cryptography.

[0118] S203. Send the verification identifier of the service server at the sending end to the service server at the sending end.

[0119] S204. Decrypt the verification identifier of the service server at the sending end according to the preset encryption method identifier in the verification identifier of the service server at the sending end to obtain the verification information of the service server at the sending end. The verification information includes the first mac address, the first username, and the first login password.

[0120] S205. Compare the verification information of the service server at the sending end with the login information.

[0121] S206. If the verification information is the same as the login information, forward the request instruction to the service server of the receiving end.

[0122] S207. Receive the response instruction returned by the service server of the receiving end, where the response instruction includes the communication information of the service server of the receiving end.

[0123] S208. Send the communication information of the service server of the receiving end to the service server of the sending end, so that the service server of the sending end can parse the communication information of the service server of the receiving end to obtain the verification identifier, the second transmission protocol type, the second communication address, and the second relay server address of the service server of the receiving end.

[0124] S209. If the service server of the sending end and the service server of the receiving end are in the same local area network, the service server of the sending end sends service data packets to the service server of the receiving end through the transmission protocol corresponding to the first transmission protocol type.

[0125] Specifically, the service server of the sending end sends a first test request to the service server of the receiving end corresponding to the second communication address.

[0126] The service server of the sending end receives the first response instruction returned by the service server of the receiving end.

[0127] The service server of the sending end sends service data packets to the service server of the receiving end through the transmission protocol corresponding to the first transmission protocol type.

[0128] Specifically, this step is generally applied to data communication within a local area network.

[0129] S210. If the service server of the sending end and the service server of the receiving end are not in the same local area network, the service server of the sending end establishes a connection with the service server of the receiving end through the relay server address, and then the service server of the sending end sends service data packets to the service server of the receiving end through the transmission protocol corresponding to the first transmission protocol type.

[0130] Specifically, the service server of the sending end sends a second test request to the service server of the receiving end corresponding to the second communication address.

[0131] If the service server of the sending end does not receive the second response instruction returned by the service server of the receiving end, the service server of the sending end sends the second test request to the first relay server corresponding to the first relay server address.

[0132] The first relay server sends the second test request to the service server of the receiving end corresponding to the second communication address according to the second communication address and the second relay server address, so that the service server of the sending end sends service data packets to the service server of the receiving end through the transport protocol corresponding to the first transport protocol type.

[0133] Specifically, this step is generally applied to data communication between different local area networks and requires a relay server for the terminals. Among them, the number of relay servers in the embodiments of the present invention is not specifically limited.

[0134] It should be noted that for the method embodiments, for simplicity of description, they are all expressed as a series of action combinations. However, those skilled in the art should know that the embodiments of the present invention are not limited by the described action sequence, because according to the embodiments of the present invention, certain steps can be performed in other sequences or simultaneously. Secondly, those skilled in the art should also know that the embodiments described in the specification are all preferred embodiments, and the actions involved are not necessarily essential for the embodiments of the present invention.

In this way, the service server sends its own communication information to the signaling server by sending a request instruction for communication information to the signaling server, and at the same time receives the communication information of other service servers returned by the signaling server, and the service servers can perform data communication through the communication information, improving the communication efficiency.
