[0051] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only configured to explain the present application and are not configured to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0053] The data transmission method provided in the embodiment of the present application can be applied to at least the following application scenarios, which are described below.

[0054] With the rapid development of the Internet, it has become an important part of people's life, work and entertainment. Information security on the Internet has also become particularly important. Especially during data transmission, data leakage often occurs, seriously affecting the security of user information.

[0055] Based on the above scenario, this application provides a data transmission method, which is described below:

[0056] Figure 1 It is a flow chart of a data transmission method provided in an embodiment of the present application.

[0057] like Figure 1 As shown, the data transmission method may include steps 110 to 140, and the method is applied to the first terminal, as shown below:

[0058] Step 110, obtaining original data and image information.

[0059] Step 120: randomly generate an encrypted image based on pre-stored image generation information and image information.

[0060] Step 130, encrypting the original data according to the key to obtain encrypted data; the key is determined according to the encrypted image.

[0061] Step 140: Send the image information and the encrypted data to the second terminal.

[0062] In the embodiment of the present application, by acquiring the original data and image information, an encrypted image is randomly generated according to the pre-stored image generation information and image information, and the original data is encrypted according to the key to obtain encrypted data, wherein the key is determined according to the encrypted image. Since the encrypted image has high randomness, the randomness of the key determined according to the encrypted image is also high. The encrypted data obtained by encrypting the original data according to the strong random key can realize high-intensity encryption of the original data and improve the security of the encrypted data. Finally, the image information and the highly secure encrypted data are sent to the second terminal, which can improve the security of data transmission.

[0063] The contents of step 110 to step 140 are described below respectively:

[0064] This involves step 110 .

[0065] Get raw data and image information.

[0066] The original data is the data that the first terminal is going to transmit to the second terminal.

[0067] The image information is used to describe the characteristics of the image, that is, the image can be generated according to the image information. The image information may include: image size and image element information, wherein the image element information includes: the number of image elements, shape characteristics of image elements and color characteristics of image elements.

[0068] For example, the image information may include: two random numbers X and Y, where X and Y are used to represent the image size, where X is the length of a horizontal column and Y is the length of a vertical column. Figure 2 shown.

[0069] The image information may also include a random number Z, which is used to represent the image element information. The number of Z values ​​is the product of X and Y. For example, if X is 3 and Y is 2, the number of Z values ​​is 6.

[0070] For example, Z=(1, 2, 3, 4, 5, 6), and its values ​​represent the colors of the image elements to be randomly acquired, namely, red, orange, yellow, green, blue, and purple, that is, the image element information of the first image element is red, the image element information of the second image element is orange, and so on.

[0071] In addition, the image element information may also include shape features, such as triangle, rectangle, and circle.

[0072] This involves step 120 .

[0073] An encrypted image is randomly generated based on pre-stored image generation information and image information.

[0074] The image generation information is information pre-agreed between the first terminal and the second terminal, and the image generation information is used to describe a generation method of the encrypted image.

[0075] In a possible embodiment, the image generation information includes first generation information and second generation information. Step 120 may specifically include the following steps:

[0076] Based on the first generation information, generate a first image according to the image information;

[0077] Based on the second generation information, the first image is encrypted to randomly generate an encrypted image.

[0078] The first generation information may be used to describe the arrangement of the encrypted image. For example, the first generation information may include: forward arrangement, forward serpentine arrangement, reverse serpentine arrangement, serpentine arrangement, etc. Figure 2 As shown, Figure 2 is the first image generated by the forward serpentine arrangement.

[0079] The first generation information is information pre-agreed between the first terminal and the second terminal, and the first generation information is used to describe a generation method of the first image.

[0080] The second generation information can be used to describe the elimination method of the first image. For example, the second generation information may include: three identical image elements adjacent in a horizontal or vertical column form a straight line elimination, three identical image elements form a triangle elimination, and three identical image elements adjacent in a diagonal direction form a straight line elimination.

[0081] The second generation information can also be used to describe the adjustment method of the first image. For example, the second generation information may include: three identical image elements adjacent in horizontal or vertical columns are replaced with preset image elements, three identical image elements forming a triangle are replaced with preset image elements, and three identical image elements adjacent diagonally are replaced with preset image elements.

[0082] The “three” identical image elements mentioned above are only exemplary descriptions and may also be other positive integers.

[0083] Thus, based on the first generation information pre-agreed between the first terminal and the second terminal, a first image with strong security can be generated according to the image information, and then based on the second generation information, the first image is encrypted to generate an encrypted image with strong randomness.

[0084] Taking adjacent oblique lines elimination as an example, at least a portion of the area to be eliminated in the first image can be as follows: Figure 3 As shown; the encrypted image obtained by eliminating adjacent diagonal lines is as follows Figure 4 shown.

[0085] The above-mentioned step of encrypting the first image based on the second generated information to randomly generate an encrypted image may specifically include the following steps:

[0086] Based on the second generation information, at least a partial area in the first image is eliminated to generate an encrypted image.

[0087] The second generated information is information pre-agreed between the first terminal and the second terminal, and the second generated information is used to describe a method of eliminating at least a partial area of ​​the first image.

[0088] Based on the second generation information, at least a partial area in the first image is eliminated to randomly generate an encrypted image, wherein after the elimination process, positions of other image elements in the first image except for at least a partial area remain unchanged.

[0089] For example, the first image may be Figure 3 As shown; the second generated information may be that three adjacent identical straight lines are eliminated diagonally. The encrypted image obtained by eliminating at least a portion of the first image based on the second generated information may be as follows Figure 4 shown.

[0090] If the second generation information is not obtained in advance, the partial area cannot be determined from the first image. Therefore, at least a partial area determined from the first image based on the second generation information is random, and the encrypted image generated by eliminating at least a partial area in the first image is also random, that is, the encrypted image is randomly generated.

[0091] Therefore, based on the second generation information, at least a partial area in the first image is eliminated to randomly generate an encrypted image, thereby ensuring the diversity and randomness of the encrypted image.

[0092] In a possible embodiment, the image information includes the second image, and step 120 may specifically include the following steps:

[0093] Based on the image generation information, at least a partial area in the second image is eliminated to generate an encrypted image.

[0094] The image information may include the second image, that is, at least a part of the second image may be eliminated directly based on the image generation information to randomly generate an encrypted image.

[0095] Among them, the image generation information can be used to describe the elimination method of the second image. For example, the second generation information may include: three identical image elements adjacent in horizontal or vertical columns form a straight line elimination, three identical image elements form a triangle elimination, and three identical image elements adjacent in diagonal directions form a straight line elimination.

[0096] The image generation information can also be used to describe the adjustment method of the second image. For example, the second generation information may include: three identical image elements adjacent in horizontal or vertical columns are replaced with preset image elements, three identical image elements forming a triangle are replaced with preset image elements, and three identical image elements adjacent diagonally are replaced with preset image elements.

[0097] For example, the second image may be Figure 3 As shown, the image generation information may be: three adjacent identical straight lines are eliminated diagonally; based on the image generation information, at least a portion of the second image is eliminated to obtain an encrypted image such as Figure 4 shown.

[0098] Therefore, based on the image generation information, at least a partial area in the second image is eliminated to randomly generate an encrypted image, thereby ensuring the diversity and randomness of the encrypted image.

[0099] This involves step 130 .

[0100] The original data is encrypted according to the key to obtain encrypted data; the key is determined according to the encrypted image.

[0101] The key can be determined by determining the order of appearance of each type of image element in the generated encrypted image and the number of appearances of each type of image element, and then encrypting the original data according to the key to obtain encrypted data.

[0102] Here, since the key is determined based on the encrypted image, the encrypted image determined based on the above steps has high randomness, so the randomness of the key determined based on the encrypted image is also high. The encrypted data obtained by encrypting the original data according to the strong random key can achieve highly random encryption of the original data, thereby improving the security of the encrypted data.

[0103] In a possible embodiment, the encrypted image includes at least one image element. Before step 130, the method further includes:

[0104] extracting at least one subkey from the encrypted image based on at least one image element;

[0105] A key is generated based on at least one subkey.

[0106] The image elements may be graphics, characters, and marks, etc.

[0107] Among them, the above-mentioned step of extracting at least one sub-key from the encrypted image based on at least one image element can specifically include the following steps: determining the order of appearance of each type of image elements in the encrypted image, and determining the number of appearances of each type of image elements, and determining the sub-key based on the order of appearance and the number of appearances.

[0108] Among them, the above-mentioned step of extracting at least one sub-key from the encrypted image based on at least one image element may also specifically include the following steps: determining the order of appearance of target image elements, the number of appearances of the target image elements is greater than a first preset threshold, or the number of appearances of the target image elements is less than a second preset threshold, and determining the sub-key based on the order of appearance of the target image elements.

[0109] For example, Figure 4 The red ball appeared first, and it appeared 13 times; the yellow ball appeared second, and it appeared 13 times; the green ball appeared third, and it appeared 13 times; the blue ball appeared fourth, and it appeared 27 times; and the purple ball appeared fifth, and it appeared 11 times.

[0110] The subkeys can be: 1×13, 2×13, 3×13, 4×27 and 5×11.

[0111] The step of generating a key according to at least one subkey may specifically include: performing concatenation processing on at least one subkey to obtain a key, namely, 13263910855.

[0112] In addition, other encryption operations may be performed on at least one subkey to generate a key, such as using a hash algorithm or compiling the subkey.

[0113] This involves step 140 .

[0114] The image information and the encrypted data are sent to the second terminal.

[0115] Specifically, the image information (X, Y and Z) may be encapsulated into an array as a request parameter and sent to the second terminal together with the encrypted data.

[0116] In the embodiment of the present application, by acquiring the original data and image information, an encrypted image is randomly generated according to the pre-stored image generation information and image information, and the original data is encrypted according to the key to obtain encrypted data, wherein the key is determined according to the encrypted image. Since the encrypted image has high randomness, the randomness of the key determined according to the encrypted image is also high. The encrypted data obtained by encrypting the original data according to the strong random key can realize high-intensity encryption of the original data and improve the security of the encrypted data. Finally, the image information and the highly secure encrypted data are sent to the second terminal, which can improve the security of data transmission.

[0117] Figure 5 It is a flow chart of a data transmission method provided in an embodiment of the present application.

[0118] like Figure 5 As shown, the data transmission method may include steps 510 to 540, and the method is applied to the second terminal, as shown below:

[0119] Step 510, receiving image information and encrypted data sent by the first terminal;

[0120] Step 520: Generate a decrypted image based on pre-stored image generation information and image information.

[0121] Step 530, extracting the key from the decrypted image.

[0122] Step 540: decrypt the encrypted data according to the key to obtain the original data.

[0123] In the embodiment of the present application, by receiving the image information and encrypted data sent by the first terminal, since the encrypted data is obtained by encrypting the original data according to the strong random key, the key is extracted from the decrypted image generated according to the pre-stored image generation information and the image information, here, only the terminal allowed to decrypt can generate a valid decrypted image, and only the terminal allowed to decrypt can extract the key from the decrypted image. The security of the key can be guaranteed, and thus, the encrypted data is decrypted according to the key, and the security of the original data can be guaranteed.

[0124] The contents of step 510 to step 540 are described below respectively:

[0125] Involves step 510.

[0126] Receive the image information and encrypted data sent by the first terminal.

[0127] The first two digits of the image information represent X, and the last two digits represent Y. For example, the image information is 1010, that is, X=10, Y=10. At the same time, the encrypted image sent by the first terminal is received.

[0128] In a possible embodiment, step 510 may specifically include the following steps:

[0129] receiving the encrypted image, image information and encrypted data sent by the first terminal;

[0130] Accordingly, step 530 may specifically include the following steps:

[0131] In the event that the encrypted image matches the decrypted image, the key is extracted from the decrypted image.

[0132] By comparing the encrypted image with the decrypted image, it is determined whether the verification is passed. Specifically, it is necessary to compare the position of the image elements, the shape of the image elements, and the color of the image elements.

[0133] If the encrypted image is exactly the same as the decrypted image, the verification is successful and the next step is to extract the key from the decrypted image.

[0134] If the encrypted image is different from the decrypted image, it means that the verification fails and the subsequent data processing steps are abandoned.

[0135] Here, the reason for the encrypted image and the decrypted image may be that the image information sent by the first terminal is different from the image information received by the second terminal, or the image generation information stored in the first terminal is different from the image generation information stored in the second terminal, or the method of extracting the key from the image information is different. If the encrypted image is different from the decrypted image, it means that the verification fails, and the subsequent steps are stopped at this time, which can reduce the amount of data processing and ensure data security.

[0136] Involves step 520.

[0137] A decrypted image is generated based on pre-stored image generation information and image information.

[0138] Specifically, a third image is generated according to the first generation information and the image information, and then a partial area in the third image is eliminated according to the second generation information to generate a decrypted image.

[0139] Involves step 530 .

[0140] Extract the key from the decrypted image.

[0141] The key can be determined by determining a first value of the number of times each type of image element of the generated encrypted image appears and a second value of the number of times each type of image element appears, and then the key is determined according to the first value and the second data. The original data is encrypted according to the key to obtain the encrypted data.

[0142] Involves step 540.

[0143] The encrypted data is decrypted according to the key to obtain the original data.

[0144] Here, the encrypted data is obtained by encrypting the original data according to a strongly random key. Here, a valid key can be obtained through the above steps, which can ensure that the encrypted data is only decrypted by a terminal that is allowed to decrypt, thereby ensuring the security of the original data.

[0145] In the embodiment of the present application, by receiving the image information and encrypted data sent by the first terminal, since the encrypted data is obtained by encrypting the original data according to the strong random key, the key is extracted from the decrypted image generated according to the pre-stored image generation information and the image information, here, only the terminal allowed to decrypt can generate a valid decrypted image, and only the terminal allowed to decrypt can extract the key from the decrypted image. The security of the key can be guaranteed, and thus, the encrypted data is decrypted according to the key, and the security of the original data can be guaranteed.
