Description

Digital seal information acquisition device

This case is about a digital seal information capture device for characterizing and extracting the printed parts of a physical seal.

When opening an account at the counter, the bank operator will ask the customer to sign or use the seal, and the bank will save the customer's signature or the seal image as the seal image. In the future, when a customer conducts a financial transaction at the counter, the bank operator will ask the customer to use a seal in a specific field of the transaction receipt, and compare whether the customer's current seal image provided by the customer is the same as the customer's seal image kept at the bank , When the comparison result is the same, the bank operator will release the financial transaction.

However, this comparison method is done through the naked eye, so it is easy to make judgment errors. Furthermore, the current seals are automatically engraved according to certain types of characters, such as regular script, official script, cursive script, and small seal. Therefore, if a third person intends to copy, as long as he sees or photographs the seal image, he can easily use the engraving machine to copy a seal that is nearly identical to the seal image.

Therefore, the traditional seal verification program has the problems of easy identification errors and easy imitation of seal images.

In view of this, this creation proposes a digital seal information capture device for scanning a physical seal. The physical seal has one end, and the end has seal information. The seal information includes at least two of concave and convex features, surface texture features, and character features. The digital seal information capturing device includes a casing and a control module, a light source and an optical scanning module arranged in the casing. The casing includes a top plate, and the top plate has a transparent window. When the end of the physical seal is located in the transparent window, the control module sends a control signal.

The optical scanning module is coupled to the control module and scans the transparent window according to the control signal to retrieve the seal information of the physical seal.

In some embodiments, the digital seal information capturing device further includes a storage module coupled to the optical scanning module to store the seal information captured by the optical scanner.

In some embodiments, the control module of the digital seal information capturing device further includes a processor for comparing the captured seal information with the existing seal information stored in the storage module.

In some embodiments, the above-mentioned digital seal information capturing device further includes a sensor disposed in the housing and coupled to the control module, and the sensor is used to sense whether the end of the physical seal is located at the Transparent window.

In some embodiments, the digital seal information capturing device further includes a light module, which is disposed on the housing and coupled to the optical scanning module. When the optical scanning module is in the first operating state, the light module The first light is displayed, and the light module displays the second light when the optical scanning module is in a second operating state.

In some embodiments, the digital seal information capturing device further includes a sound effect module, which is disposed in the housing and coupled to the optical scanning module. When the optical scanning module is in the first operating state, the sound effect module emits The first sound effect, when the optical scanning module is in the second operating state, the sound effect module emits the second sound effect.

In some embodiments, the digital seal information capturing device further includes a positioning member disposed on the top plate and located at the periphery of the transparent window.

In some embodiments, the transparent window of the digital seal information capturing device corresponds to the optical scanning module.

In some embodiments, the concave-convex feature of the above-mentioned seal information is related to the indentation depth of the text engraved on the end of the physical seal, and the surface texture feature is related to the surface color, stripes or roughness of the end of the physical seal. The feature is related to the outline of the text engraved on the end of the physical seal.

In some embodiments, the above-mentioned character feature is more related to the sharpness of the outline of the text engraved on the end of the physical seal.

In some embodiments, the digital seal information capturing device further includes a communication module, which is disposed in the casing and coupled to the control module.

Figures 1 to 4 are respectively a schematic diagram, a schematic diagram of a module, a three-dimensional view of a physical seal, and a schematic diagram of the end of the first embodiment of the created digital seal information capture device, which depicts the digital seal information capture used to scan the physical seal 9取装置100。 Take the device 100. The physical seal 9 has one end 91, and the end 91 has seal information. The seal information includes at least two of concave-convex features, surface texture features, and character features. For ease of description, the following embodiment assumes that the seal information includes both concave-convex features and surface features. The texture feature and character feature are taken as examples to illustrate. As shown in Figures 3 and 4, the so-called concave-convex features are equivalent to the indentation depth of the text "Wang Yier"; the surface texture features are equivalent to the surface color, streaks, or roughness formed by the natural material of the physical seal 9; The character features are equivalent to the outline of the text "Wang Yier" on the end 91 of the physical seal 9, including the sharpness of the engraving.

The digital seal information capturing device 100 includes a housing 110 and a control module 120, a light source 190, and an optical scanning module 130 disposed in the housing 110. The housing 110 includes a top plate 111 with a transparent window 112 corresponding to the position of the optical scanning module 130. Ideally, the top plate 111 can be very thin so that the transparent window 112 is directly close to the optical scanning module 130. When the end 91 of the physical seal 9 abuts and fits on the transparent window 112, the control module 120 sends out a control signal, and the light source 190 is coupled to the control module 120 and can be based on the output from the control module 120 The control signal emits light having a working wavelength (for example, infrared rays) toward the transparent window 112. The optical scanning module 130 is coupled to the control module 120 and can control the light of the working wavelength to scan the transparent window 112 according to the control signal issued by the control module 120 to capture the seal information of the end 91 of the physical seal 9.

Through the digital seal information capturing device 100, the physical seal 9 no longer can only present character features through the ink of the stamp pad, but can further carry surface texture features and three-dimensional concave-convex features. Especially, when the user makes the physical seal 9, due to factors such as the material of the physical seal 9 itself, the model and age of the machine and the engraver, the technology of the engraver, etc., the depth, sharpness, and texture of the score cannot be completely copied. .

For example, on the market, the materials used as the base of the physical seal are different, for example: wood, jade, ivory, etc., and based on the laws of physics, the reflectance of seals of different materials will also be different. Obtain the unique grayscale intensity information of the physical seal material. As shown in Figures 17 and 18, when the reflection coefficient of the material of the physical seal 9 is weak, the character 92A will have a darker gray scale value as shown in Figure 17. When the material of the physical seal 9 has a strong reflection coefficient , The character 92B will have a lighter grayscale value as shown in FIG. 18. Therefore, if the stealer imitates the same font, the verification will fail due to the difference between the material of the seal and the existing data information, which can greatly improve the verification accuracy. Even stamps of the same material, such as wood stamps, have different textures due to different batches and different cuts of wood. In addition, under the analysis of the digital seal information acquisition device 100 of this creation, different wood textures (such as bifurcations, breakpoints, etc.) will reflect different grayscale intensities. In other words, even if the physical seal is made of wood, the surface texture feature points presented will be different, as shown in the character 92C in FIG. 19 and the character 92D in FIG. 20.

In addition, the gray scale intensity of the recessed part of the physical seal 9 will be different due to different dent depths. In this way, the unique three-dimensional gray scale intensity information of the physical seal 9 can be obtained, as shown in Figure 21. The dent 93A and the dent 93B in FIG. 22 are shown. Traditional seal recognition can only recognize flat fonts, and it is inevitable that people who intend to steal font images to imitate forgery seals can greatly improve the authenticity of the seal on behalf of the parties.

In addition, traditionally, the physical seal 9 is directly printed on the paper with ink pad, and various impurities may appear due to the printing process. Even if the plane image obtained afterwards is scanned by computer and image processing, the impurities and the real words cannot be separated ideally. However, the digital seal information capture device 100 of this creation directly scans the body of the end 91 of the physical seal 9. It can capture various data and information at the same time by using the different physical characteristics of impurities and the seal body to filter out Relatively special data, and then filter out impurities, get closer to the real seal information, and avoid secondary distortion.

Since the captured seal information is not only character features (character contours and edge sharpness), but also includes concave and convex features and surface texture features, so unless the user's physical seal 9 is stolen, a third person with bad intentions It is difficult to change the physical seal 9 that has the same seal information as the user's physical seal 9. The bank only needs to scan the user's physical seal 9's seal information through the created digital seal information acquisition device 100 and save it in the server. In the future, when the user has financial transaction needs and needs to identify the authenticity of the seal, the bank only needs to scan it again Once the user's physical seal 9's seal information is compared with the seal information stored in the server, there is no need to use ink on the stamp pad, which saves the trouble of cleaning the physical seal 9 and also allows the user's physical seal 9 can be applied to non-counter online transactions.

Referring to FIG. 16, it is a schematic flow diagram of the digital seal information verification method using the digital seal information capture device created by this invention. When the user goes to the bank office to conduct a counter transaction, the bank counter clerk can ask the user to provide the physical seal 9, then place the physical seal 9 on the digital seal information acquisition device and scan the end 91 of the physical seal 9 (step S1 ). During the scanning process, the digital seal information capturing device captures at least two of the concave and convex features, surface texture features, and character features of the end 91 of the physical seal 9, and uses at least two of the above three features as a piece of seal information to be verified ( Step S2). Then, the bank-side server reads the bank-side database and extracts one of the existing seal information that the user keeps in the bank. The existing seal information also includes the concave and convex features, surface texture features, and characters corresponding to the seal information to be verified Features (step S3) at least two. Then, the bank-side server compares whether the seal information to be verified matches the existing seal information (step S4). Of course, the more features of the compared seal information, the more accurate the identification of the seal. When the to-be-verified seal information does not match the existing seal information, the bank-side server sends a verification failure message (step S5). When the to-be-verified seal information matches the existing seal information, the bank-side server sends a verification pass message (step S5). S6). In some embodiments, the above steps S4, S5, and S6 can also be executed by a digital seal information capturing device. For example, the control module 120 may include a processor for comparing the captured seal information with the storage module. Existing seal information of group 140.

In addition to counter transactions, the digital seal information verification method using the digital seal information capture device created by this creation can also be applied to online transactions. When a user logs in to the bank’s online banking via a local personal computer, smart phone or tablet computer and tries to perform an online transaction, the bank server can first detect whether the local user has acquired the digital signature information device Interconnect with personal computers, smart phones or tablets. If not, prompt the local user to install the digital signature information acquisition device. Then, the remote server prompts the local user to place the physical seal 9 on the digital seal information capturing device. Then, it is detected whether the end 91 of the physical seal 9 is completely located in a scanning area, where the scanning area is equivalent to the transparent window 112 of the above-mentioned digital seal information capturing device. When it is confirmed that the end 91 of the physical seal 9 is completely within the scanning area, the end 91 of the physical seal 9 is scanned (step S1). During the scanning process, the digital seal information capturing device captures at least two of the concave and convex features, surface texture features, and character features of the end 91 of the physical seal 9, and uses at least two of the above three features as a piece of seal information to be verified ( Step S2). Then, the bank-side server reads the bank-side database and extracts one of the existing seal information that the user keeps in the bank. The existing seal information also includes the concave and convex features, surface texture features, and characters corresponding to the seal information to be verified Features at least two (step S3). Then, the bank-side server compares whether the seal information to be verified matches the existing seal information (step S4). Of course, the more features of the compared seal information, the more accurate the identification of the seal. When the seal information to be verified does not match the existing seal information, the bank server sends a verification failure message (step S5) and rejects the execution of the online transaction. When the seal information to be verified matches the existing seal information, the bank The server sends a verification pass message (step S6) to the local user's personal computer, smart phone or tablet, and accepts the execution of the online transaction.

In some embodiments, the above-mentioned step S6 can further send a prompt message to the local user's personal computer, smart phone or tablet computer, prompting the user to reposition the end 91 of the physical seal 9 in the scanning area, and the user is correct After the physical seal 9 is repositioned locally, the above steps S1 to S4 are performed again.
