[0038] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0039] In the description of this application, it should be understood that the terms "first", "second", "third", etc. are only used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence, nor can they be understood as indicating or implying relative importance. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0040] Example 1

[0041] This embodiment discloses a method for encrypting video stream data. Figure 1 and 2 ,include:

[0042] S101. Obtain original video stream data, user ID and member ID. Specifically, the original video stream data is 00000001, the user ID is 00000001, and the member ID is 00000010.

[0043] S102, invert the original video stream data, and perform hexadecimal encoding on the inverted video stream data. The original video stream data 00000001 is inverted to 11111110, and the inverted video stream data 11111110 is used as the first data set; the first data set is hexadecimal encoded to obtain a second data set: FE.

[0044] S103, dividing the hexadecimal-encoded video stream data into several data segments, adding the user ID and the member ID to the data segments and connecting them with a flag bit to obtain the encrypted video stream data, wherein the flag bit is a randomly generated hexadecimal number with a value range of 9-F.

[0045] Specifically, step S103 includes:

[0046] Each bit of the hexadecimal video stream data is decomposed and processed, so that each bit of the video stream data is converted into a data segment: each bit of the hexadecimal video stream data is divided by a preset value, and if it can be divided, it is converted into a data segment containing a number of quotients, wherein the specific number of data in the data segment is determined by the specific value of the preset value. For example, in this embodiment, the preset value is 2, E in the second data set FE is divided by 2, E is divisible by 2, E / 2=7, that is, E can be decomposed into 7 and 7, E is converted into a data segment with a content of 77, and 77 is used as the third data set.

[0047] If a certain bit in the hexadecimal video stream data cannot be divided by the preset value, a modulus operation is performed to obtain a remainder after the division operation is performed to obtain a quotient, and the remainder is added to the quotient obtained by the division to obtain a digit of the data segment, and the remaining digits of the data segment are the quotient obtained by the division, wherein the specific number of data in the data segment is determined by the specific value of the preset value. When the preset value is 2, F in the second data set FE is divisible by 2, F / 2=7, F cannot be divided by 2, F%2=1, 1+7=8, that is, F can be decomposed into 7 and 8.

[0048] Before decomposing each bit of the hexadecimal video stream data, the video stream data is traversed to obtain the size relationship between each adjacent data, and the decomposition results of the video stream data that cannot be divided by the preset value and needs to be modulo-operated are sorted according to the size relationship between each adjacent data. In this embodiment, if the second data set is FE, F is converted into a data segment with a content of 87, and 87 is used as the fourth data set. If it is EF, F is converted into a data segment with a content of 78.

[0049] Each bit of the data segment is checked to determine whether it meets the preset conditions: when the preset value is 2, since the maximum quotient that can be obtained when a hexadecimal number is divided by the preset value is 7, 77 and 87 are compared with 8 respectively to determine whether they meet the preset condition of being less than or equal to 8. If the preset condition is met, it is considered that the decomposition processing is correct. The preset value can also be 3, 4, etc. according to actual needs. The relevant calculation process involved in different preset values ​​is the same as above and will not be repeated here.

[0050] The user ID 00000001 and the member ID 00000010 are added to the third data set and the fourth data set respectively, and connected by a flag bit, wherein any number from the hexadecimal numbers 9 to F is selected as the flag bit. In this embodiment, A is selected as the flag bit, and the third data set after mixed coding is: 00000001A00000010A77; the fourth data set after mixed coding is: 00000001A00000010A87.

[0051] And 00000001A00000010A77 is used as the fifth data set, and 00000001A00000010A87 is used as the sixth data set. The fifth data set and the sixth data set are the encrypted video stream data.

[0052] Specifically, before step S102, the following steps are included:

[0053] Authenticate the obtained user ID and member ID;

[0054] If the authentication is passed, the original video stream data is inverted;

[0055] If the authentication fails, the encryption process ends.

[0056] The video stream data encryption method disclosed in this embodiment uses the inversion method to perform the first step of processing the original video stream data, so that the video stream data is "wrong" from the beginning of the transmission process, and divides the hexadecimal-coded video stream data into several data segments by integer and modulus division to achieve decomposition processing with verification; then the hexadecimal flag bit, binary user ID, member ID and hexadecimal data segment are combined for mixed encoding to achieve multiple encryption to prevent unauthorized users from pulling the stream for parsing.

[0057] Example 2

[0058] This embodiment discloses a video stream data decryption method, which is used to decrypt the encryption method described in Embodiment 1. Figure 3 ,include:

[0059] S201, identifying a flag bit in encrypted video stream data.

[0060] Specifically, step S201 includes:

[0061] The encrypted video stream data 00000001A00000010A77 and 00000001A00000010A87 are obtained.

[0062] Each bit of the encrypted video stream data is checked to determine whether there is a hexadecimal number in the value range of 9-F. If so, the bit is a flag bit: it is recognized that there is a hexadecimal number A in 00000001A00000010A77 and 00000001A00000010A87, so A is a flag bit.

[0063] S202: Based on the flag bit, the encrypted video stream data is divided to obtain a user ID, a member ID and a data segment.

[0064] Based on the flag bit A, 00000001A00000010A77 and 00000001A00000010A87 are divided to obtain 00000001, 00000010, 77 and 87, among which the binary numbers 00000001 and 00000010 are the user ID and member ID, and the hexadecimal numbers 77 and 87 are the data segments. 77 is used as the seventh data set and 87 is used as the eighth data set.

[0065] S203, performing operation processing on the data segment, converting the operation result into a binary number and negating it, to obtain original video stream data.

[0066] Specifically, step S203 includes:

[0067] The seventh data set and the eighth data set are added in hexadecimal to obtain a calculation result FE: 77+87=FE.

[0068] The operation result FE is converted into binary to obtain: 11111110; the binary number 11111110 is inverted to obtain 00000001. At this time, 00000001 is the original video stream data.

[0069] Example 3

[0070] This embodiment discloses a video stream data transmission system. Figure 4 , including a user end 100, a first server end 200, a second server end 300 and a backend module 400, specifically:

[0071] The user terminal 100 is used to send a user ID, a member ID and a video request signal according to a user instruction;

[0072] The first server 200 is connected to the user terminal 100 and is used to authenticate the user ID and the member ID according to the video request signal, and send a video stream data request if the authentication is successful;

[0073] The second server 300 is connected to the first server 200, and is used to obtain and encrypt the original video stream data using the encryption method described in Example 1 according to the video stream data request from the first server, and send the encrypted video stream data to the first server, and the first server uses the decryption method described in Example 2 to decrypt the data;

[0074] The backend module 400 is connected to the second server 300 and is used to store original video stream data, user ID and member ID.

[0075] For the specific encryption process, please refer to Example 1, and for the specific decryption process, please refer to Example 2, which will not be repeated here.

[0076] The video stream data transmission system provided in this embodiment divides the server in the prior art into two parts, namely, a first server end 200 and a second server end 300. The first server end 200 and the second server end 300 as well as the second server end 300 and the back-end module 400 communicate through the system's internal http protocol, and the user end 100 and the first server end 200 communicate through traditional http or https, so that the user end 100 can only access the first server end 200, and cannot directly access the back-end module 400, nor can it access the back-end module 400 through the first server end 200; the original video stream data is protected by performing encryption operations such as inversion, hexadecimal conversion, decomposition processing, and mixed coding and corresponding decryption operations on the original video stream data to prevent it from being pulled and parsed by unauthorized users.
