With the development of the big data era, generally, the online transmission method is adopted to transmit and process the network signature and seal data.

[0003] The invention with the patent publication number CN112848710A discloses a financial security signature and seal system, including a fixed base, a financial seal, and a cloud data server; a seal groove is provided on the fixed base, and the seal end of the financial seal is arranged in the seal groove; a seal locking component is arranged in the seal groove, an internal cavity is arranged in the fixed base, a base control unit is arranged in the internal cavity, and the financial seal is fixed in the seal groove through the seal locking component; the base control unit includes a locking component control circuit, a network communication unit, a base positioning unit, and a control unit processor. The technical solution of this application fixes and stores the financial seal and authorizes its use, improving the security of the use of the financial seal.

[0004] In the financial security signature and seal system, when the corresponding trading parties draw up an online contract, they need to sign the online contract with the corresponding financial signature and seal. Therefore, the entire financial signature and seal data needs to be transmitted through the corresponding network channel. In the specific transmission process, since the entire financial signature and seal data is not encrypted, it is very easy for the signature and seal data to be stolen by external illegal personnel during transmission, causing great economic losses. Summary of the Invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art; for this purpose, the present invention proposes a financial security signature and seal system for solving the technical problem that the signature and seal data is easily stolen by external illegal personnel during transmission because the entire financial signature and seal data is not encrypted.

[0006] To achieve the above object, according to an embodiment of the first aspect of the present invention, a financial security signature and seal system is proposed, including: A financial signature and seal image acquisition end, which acquires the financial signature and seal image to be transmitted for transaction and transmits the acquired financial signature and seal image into the image preprocessing unit; An image preprocessing unit, which preprocesses the financial signature and seal image, performs light and dark image segmentation processing on the financial signature and seal image, so that the financial signature and seal image is segmented into a bright pixel image to be processed and a dark pixel image to be processed, and transmits the processed bright pixel image to be processed and dark pixel image to be processed into the encryption segmentation processing unit; An encryption segmentation processing unit segments the to-be-processed image of bright pixels and the to-be-processed image of dark pixels, divides each group of to-be-processed images into six groups of micro-images, marks the micro-images, integrates the marks with the corresponding micro-images at the same time, performs subscript identification processing on the marks, then bundles the processed micro-images into corresponding data packets, and transmits the data packets into the path selection unit; The path selection unit transmits different data packets through different network path channels, so that different data packets are transmitted into the corresponding receiving end, and a merging processing unit is arranged in the receiving end. The merging processing unit extracts the micro-images inside the data packets and integrates the micro-images into a financial signature image.

[0007] Preferably, the specific method for the image preprocessing unit to preprocess the financial signature image is as follows: Perform dark tone processing on the financial signature image, modify the tone parameter to X1, X1 is a preset parameter, X1 is the lowest tone value, extract the bright area inside the financial signature image at this time, and mark this bright area as the to-be-processed image of bright pixels; Perform bright tone processing on the financial signature image, modify the tone parameter to X2, X2 is a preset parameter, X2 is the highest tone value, extract the dark area inside the financial signature image at this time, and mark this dark area as the to-be-processed image of dark pixels.

[0008] Preferably, the specific steps for the encryption segmentation processing unit to segment the to-be-processed image are as follows: S1. Extract the to-be-processed image of bright pixels, and divide the to-be-processed image of bright pixels into six groups of bright micro-images. Perform marking processing on the six groups of bright micro-images with the fitting mark i, where i = 1, 2,..., 6. When i = 1, it represents the first group of bright micro-images. When i = 2, it represents the second group of bright micro-images,..., and when i = 6, it represents the sixth group of bright micro-images; S2. And according to the corresponding positions of the six groups of bright micro-images, perform subscript identification processing on each fitting mark i. There is a subscript 2 at the lower right corner and a subscript 3 at the bottom of the mark 1, indicating that the bright micro-image with the mark 2 is on the right side of the micro-image with the mark 1, and the bright micro-image with the mark 1 is below the bright micro-image with the mark 3. In the third group of bright micro-images, there is a subscript 1 at the upper end, a subscript 4 at the lower right corner, and a subscript 5 in the middle at the bottom of the mark 3, indicating that the bright micro-image with the mark 1 is above the bright micro-image with the mark 3, and the bright micro-image with the mark 4 is on the right side of the bright micro-image with the mark 3; S3. Bundle the fitting mark i with the bright micro-images, and transmit the processed several groups of bright micro-images into the path selection unit. The path selection unit sorts and bundles the multiple groups of bright micro-images into bright data packets; S4. Then extract the dark pixel image to be processed, and divide the dark pixel image to be processed into six groups of dark micro-images. Mark the six groups of dark micro-images with the fitting label k, where k = 1, 2, ……, 6, and repeat step S2 and step S3. Process the six groups of dark micro-images in the same way as the six groups of bright micro-images, and transmit the processed several groups of dark micro-images to the path selection unit. The path selection unit sorts and bundles the multiple groups of dark micro-images into a dark data packet.

[0009] Preferably, the path selection unit transmits the bright data packet and the dark data packet through different network path channels. The bandwidths of the two network path channels are 10 bit / s and 15 bit / s respectively. Obtain the internal data capacity of the bright data packet and the dark data packet, obtain the data packet with a larger data capacity, and transmit the data packet with a larger capacity through the network path channel with a bandwidth of 15 bit / s, and transmit the data packet with a smaller capacity through the network path channel with a bandwidth of 10 bit / s.

[0010] Preferably, the way for the merging processing unit to integrate the micro-images inside the data packet is as follows: Extract the dark data packet, sequentially extract the fitting labels of multiple groups of dark micro-images inside the dark data packet, and then according to the subscript identifier of the fitting label, integrate the multiple groups of dark micro-images to make the multiple groups of dark micro-images integrated into the dark pixel image to be processed; Extract the bright data packet, sequentially extract the fitting labels of multiple groups of bright micro-images inside the bright data packet, and then according to the subscript identifier of the fitting label, integrate the multiple groups of bright micro-images to make the multiple groups of bright micro-images integrated into the bright pixel image to be processed; Integrate the dark pixel image to be processed and the bright pixel image to be processed to make the dark pixel image to be processed and the bright pixel image to be processed integrated into a complete financial signature image.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: preprocess the financial signature image during the transmission process, divide the financial signature image into a bright pixel image to be processed and a dark pixel image to be processed by changing the hue parameter, and then sequentially perform segmentation processing on the bright pixel image to be processed and the dark pixel image to be processed, so that the bright pixel image to be processed and the dark pixel image to be processed are sequentially divided into six groups of micro-images. Then, use the corresponding fitting label to fit and bundle each group of micro-images, perform subscript identification processing on the fitting label according to the position of the corresponding micro-image, bundle the processed micro-images into the corresponding data packet. The path selection unit transmits different data packets through different network path channels. After transmitting the corresponding data packet to the corresponding receiving end, the merging processing unit then integrates the micro-images inside the data packet to make the micro-images merged into the bright pixel image to be processed and the dark pixel image to be processed; Next, the bright pixel image to be processed and the dark pixel image to be processed are combined and integrated into a financial signature image. By transmitting and processing the financial signature image in this way, the security of the financial signature image during transmission can be effectively improved, and the financial signature image can be prevented from being stolen by external illegal personnel.

The segmentation processing steps are as follows: Perform a dark tone processing on the financial signature image, modify the tone parameter to X1, X1 is a preset parameter, X1 is the lowest tone value, extract the bright area inside the financial signature image at this time, and mark this bright area as the bright pixel image to be processed; Perform a bright tone processing on the financial signature image, modify the tone parameter to X2, X2 is a preset parameter, X2 is the highest tone value, extract the dark area inside the financial signature image at this time, and mark this dark area as the dark pixel image to be processed; Transfer the image to be processed with bright pixels and the image to be processed with dark pixels into the encryption and segmentation processing unit. The encryption and segmentation processing unit segments the image to be processed with bright pixels and the image to be processed with dark pixels into six groups of micro-images, and sequentially marks each group of micro-images, integrates the marks with the corresponding micro-images, and transfers the marked micro-images into the path selection unit. The processing steps are as follows: S1. Extract the image to be processed with bright pixels, segment the image to be processed with bright pixels into six groups of bright micro-images, and perform marking processing on the six groups of bright micro-images with the fitting mark i, where i = 1, 2,..., 6. When i = 1, it represents the first group of bright micro-images; when i = 2, it represents the second group of bright micro-images;..., when i = 6, it represents the sixth group of bright micro-images. S2. And according to the corresponding positions of the six groups of bright micro-images, perform subscript identification processing on each fitting mark i. After the subscript processing, the expression form of each fitting mark i is as Figure 2 shown (specifically, there is a subscript 2 at the lower right corner and a subscript 3 at the bottom of the mark 1, indicating that the bright micro-image marked 2 is on the right side of the micro-image marked 1, and the bright micro-image marked 3 is below the micro-image marked 1. For example, in the third group of bright micro-images, there is a subscript 1 at the upper end, a subscript 4 at the lower right corner, and a subscript 5 in the middle at the bottom of the mark 3, indicating that the bright micro-image marked 1 is above the bright micro-image marked 3, and the bright micro-image marked 4 is on the right side of the bright micro-image marked 3). S3. Bundle the fitting mark i with the bright micro-images, and transfer the processed several groups of bright micro-images into the path selection unit. The path selection unit sorts and bundles the multiple groups of bright micro-images into a bright data packet. S4. Then extract the image to be processed with dark pixels, segment the image to be processed with dark pixels into six groups of dark micro-images, and perform marking processing on the six groups of dark micro-images with the fitting mark k, where k = 1, 2,..., 6, and repeat steps S2 and S3, perform the same processing method as the six groups of bright micro-images on the six groups of dark micro-images, and transfer the processed several groups of dark micro-images into the path selection unit. The path selection unit sorts and bundles the multiple groups of dark micro-images into a dark data packet.

[0015] Perform fitting bundling on each group of micro-images with the corresponding fitting mark, perform subscript identification processing on the fitting mark according to the position of the corresponding micro-image, bundle the processed micro-images into the corresponding data packets. The path selection unit transmits different data packets through different network path channels. After transmitting the corresponding data packets to the corresponding receiving ends, the merging processing unit then integrates the micro-images inside the data packets to merge the micro-images into the image to be processed with bright pixels and the image to be processed with dark pixels. The path selection unit transmits the plain data packet and the dark data packet through different network path channels. The bandwidths of the two groups of network path channels are 10 bit / s and 15 bit / s respectively. It obtains the internal data capacities of the plain data packet and the dark data packet, obtains the data packet with a larger data capacity, and transmits the data packet with a larger capacity through the network path channel with a bandwidth of 15 bit / s, and transmits the data packet with a smaller capacity through the network path channel with a bandwidth of 10 bit / s; The merging processing unit is set at the receiving end corresponding to the financial signature image, integrates the micro-images inside the data packet, and then integrates the dark pixel image to be processed and the bright pixel image to be processed to form a financial signature image. The specific processing method is as follows: Extract the dark data packet, sequentially extract the fitting marks of multiple groups of dark micro-images inside the dark data packet, and then integrate the multiple groups of dark micro-images according to the subscript identifiers of the fitting marks, so that the multiple groups of dark micro-images are integrated into a dark pixel image to be processed; Extract the plain data packet, sequentially extract the fitting marks of multiple groups of plain micro-images inside the plain data packet, and then integrate the multiple groups of plain micro-images according to the subscript identifiers of the fitting marks, so that the multiple groups of plain micro-images are integrated into a bright pixel image to be processed; Integrate the dark pixel image to be processed and the bright pixel image to be processed, so that the dark pixel image to be processed and the bright pixel image to be processed are integrated into a complete financial signature image. By using this transmission method, the security during the transmission process can be improved, and the internal data of the financial signature image can be effectively prevented from being stolen by external illegal personnel.

[0016] Embodiment 2 In the specific implementation process of this embodiment, compared with Embodiment 1, the main difference is that the bandwidths of different network path channels are 15 bit / s and 20 bit / s respectively.

[0017] Some of the data in the above formula are calculated by removing the dimension and taking its numerical value. The formula is obtained by software simulation of a large amount of collected data to obtain a formula closest to the actual situation; the preset parameters and preset thresholds in the formula are set by those skilled in the art according to the actual situation or obtained through simulation of a large amount of data.

[0018] Working principle of the present invention: Preprocess the financial signature image during the transmission process. The financial signature image is segmented into a bright pixel image to be processed and a dark pixel image to be processed by changing the hue parameter. Then, the bright pixel image to be processed and the dark pixel image to be processed are sequentially segmented, so that the bright pixel image to be processed and the dark pixel image to be processed are sequentially segmented into six groups of micro-images. Then, each group of micro-images is bonded and bundled with a corresponding fitting mark, and the fitting mark is subscripted according to the position of the corresponding micro-image. The processed micro-images are bundled into corresponding data packets. The path selection unit transmits different data packets through different network path channels. After the corresponding data packets are transmitted to the corresponding receiving end, the merging processing unit integrates the micro-images inside the data packets, so that the micro-images are merged into a bright pixel image to be processed and a dark pixel image to be processed; Then, the bright pixel image to be processed and the dark pixel image to be processed are merged and integrated into a financial signature image. By using this method to transmit and process the financial signature image, the security of the financial signature image during the transmission process can be effectively improved, and the financial signature image can be prevented from being stolen by external illegal personnel.
