When the intelligent stamp device 100 works, the intelligent stamp device can communicate with the block chain nodes through the communication module 103, and send information to the block chain nodes and receive information returned by the block chain nodes.
In intelligent stamp device 100, drive module 104 may include motors, gears, etc. that provide the driving function. Movable contact 105 may include a plurality of independently movable sub-contacts disposed on the stamp surface of intelligent stamp device 100, and vertically moved in a direction perpendicular to the stamp surface or horizontally moved in a direction parallel to the stamp surface by driving module 104. In practical application, the driving module 104 may receive information of the barcode image transmitted by the block link point through the communication module 103, and drive the sub-contacts to move according to the information of the barcode image, so that the moved sub-contacts cover the document to obtain an image which is the same as the barcode image corresponding to the received information of the barcode image. The barcode image may be a two-dimensional code image. The information of the barcode image may be a code value of the barcode image or image data. The scanned bar code image may have corresponding content as the generation time information of the bar code image. For example, after a user scans an image obtained by covering a file with a sub-contact on the intelligent stamp device through a mobile phone, a string of time information can be obtained, and the time information represents the generation time of the corresponding barcode image.

Wherein the administrator has the authority to set legal persons who can stamp using the intelligent stamp device 100 through the user terminal 300.
Fig. 5 is a block chain based sealing processing method provided in an embodiment of the present specification, and the method is applied to a block chain node, such as the block chain node 200 described above, and as shown in fig. 5, the method includes the following steps:
step S502, a stamping request sent by the intelligent stamping equipment is obtained; the intelligent seal device comprises a seal device, a seal control module and a control module, wherein the seal surface of the intelligent seal device is preset with user-defined seal content;
step S504, a first intelligent contract in the block chain is called, and stamping behavior identification information is generated for the stamping behavior according to the stamping request; the stamping behavior identification information generated for each stamping behavior is different; the stamping behavior identification information is used for arranging the intelligent stamp equipment on the surface of the stamp;
step S506, returning stamping behavior identification information to the intelligent stamping equipment;
step S508, acquiring image data of the stamped file sent by the intelligent stamping equipment after the stamping action is finished; the stamped file is a file stamped with stamping behavior identification information and user-defined stamping content;
step S510, in the block chain, the stamping behavior identification information and the image data of the stamped file are stored in association, so as to verify the authenticity of the stamping behavior to be verified.
In the embodiment of the description, the block link points may send stamping behavior identification information generated for the current stamping behavior to the intelligent stamp device according to a stamping request of the intelligent stamp device, and the stamping behavior identification information is used for the intelligent stamp device to be arranged on the surface of the stamp, so that the intelligent stamp device stamps on a file during stamping. Because the stamping behavior identification information generated for each stamping behavior is different, the images stamped by the same intelligent stamp device in each stamping process are different, and the forging difficulty of the stamp is improved. And the block chain link point can also acquire the image data of the stamped file sent by the intelligent stamping equipment after the stamping action is finished, and the image data of the stamped file and the stamping action identification information generated for the stamping action are stored in a block chain in a correlation mode, so that the advantage that the data in the block chain cannot be falsified is achieved, and the effect of verifying the authenticity of the stamping action to be verified is achieved.
In step S502, the block link point receives a stamping request sent by the intelligent stamping device. In one embodiment, the intelligent stamp device may be provided with a switch, the switch is pressed to request to start the intelligent stamp device before stamping by a user each time, and the intelligent stamp device sends a stamping request to the block link point after detecting that the user presses the switch. The stamping request can carry the stamp identification information of the intelligent stamp device.
As described above, the user-defined stamping content is preset in the stamp surface of the intelligent stamp device. For example, before purchasing the intelligent stamp device, the user can inform the producer of the intelligent stamp device, and the user-defined stamping content is engraved on the stamp surface of the intelligent stamp device in advance. The user-defined stamping content may be a user name or a company name. Similarly, the stamp identification information of the intelligent stamp device can be carved on the stamp surface of the intelligent stamp device in advance by the production party of the intelligent stamp device.
In step S504, the block link point calls a first intelligent contract in the block chain, and generates the stamping behavior identification information for the current stamping behavior according to the stamping request. In step S506, the block link node further returns the stamping behavior identification information generated for the current stamping behavior to the intelligent stamping device.
In this embodiment, a first intelligent contract is pre-deployed in the block chain node, and the stamping behavior identification information may be generated by the first intelligent contract. As can be seen from the structure of the intelligent stamp device described in fig. 1, in an embodiment, a communication module in the intelligent stamp device may send a stamping request to a block chain node, and receive stamping behavior identification information returned by the block chain node through the communication module.
In one embodiment, the block link point calls a first intelligent contract in the block chain, and generates the stamping behavior identification information for the current stamping behavior according to the stamping request, specifically:
(a1) the block chain node calls a first intelligent contract in the block chain, extracts the personnel information of the stamping personnel of the stamping action at this time from the stamping request, and searches prestored personnel information of legal personnel allowed to stamp corresponding to the intelligent stamping equipment in the block chain;
(a2) and if the personnel information of the stamping personnel is matched with the found personnel information of the legal personnel, determining that the stamping action is allowed, and generating stamping action identification information for the stamping action.
The stamping request can carry the personnel information of the stamping personnel of the stamping action. The person information may be a face image of the person. As mentioned above, the intelligent seal device may be provided with a switch, and before the user stamps, the switch request is pressed to start the intelligent seal device, and after the intelligent seal device detects the operation that the user presses the switch, the face image of the stamping person may be acquired through the camera therein, and the face image of the stamping person is carried in the stamping request and sent to the block chain node. The stamping request can also carry the stamp identification information of the intelligent stamp device.
The block chain node also stores the personnel information of legal personnel corresponding to the intelligent seal device in advance, and the personnel information of the legal personnel can be acquired from the user terminal bound with the intelligent seal device. Therefore, in one embodiment, before the blockchain link point searches the prestored personnel information of the legal personnel allowed to stamp corresponding to the intelligent stamp device in the blockchain, the method can further comprise the following steps: and acquiring the personnel information of legal personnel allowed to be stamped, which corresponds to the intelligent stamp device and is sent by the user terminal bound with the intelligent stamp device, and storing the personnel information in the block chain. For example, an administrator of the intelligent seal device sets the personnel information of the legal personnel who can use the intelligent seal device 100 to seal through the user terminal, the user terminal sends the personnel information of the legal personnel and the seal identification information of the intelligent seal device to the blockchain nodes, and the blockchain nodes store the personnel information of the legal personnel and the seal identification information of the intelligent seal device in an associated manner. The person information of the legitimate person may be a face image of the person.
And calling a first intelligent contract by the block chain node, extracting the personnel information of the stamping personnel of the stamping behavior and the seal identification information of the intelligent seal equipment from the stamping request, and searching prestored personnel information of legal personnel corresponding to the intelligent seal equipment according to the seal identification information of the intelligent seal equipment in the block chain. If the extracted personnel information of the stamping personnel is the same as the found personnel information of the legal personnel, determining to allow the stamping action, generating stamping action identification information for the stamping action, and if the extracted personnel information of the stamping personnel is different from the found personnel information of the legal personnel, determining not to allow the stamping action, and returning a notification message of refusing stamping to the intelligent stamping equipment. The extracted personnel information of the stamping personnel is the same as the personnel information of the found legal personnel, and the comparison between the facial image of the stamping personnel and the facial image of the found legal personnel can be consistent.
The block chain node can generate stamping behavior identification information for the stamping behavior at this time through a first intelligent contract and returns the stamping behavior identification information to the intelligent stamping equipment. The block link points can generate corresponding stamping behavior identification information for each stamping behavior, and the stamping behavior identification information generated for each stamping behavior is different. The stamping behavior identification information can be information of a bar code image, the bar code image can be a two-dimensional code image, and the information of the bar code image can be code values or image data of the bar code image. The stamping behavior identification information is used for setting the intelligent stamp equipment on the surface of the stamp. The block chain nodes can generate different stamping behavior identification information for each stamping behavior through the first intelligent contract in a mode of randomly generating information, for example, the block chain nodes can generate different two-dimensional code images for each stamping behavior through the first intelligent contract in a mode of randomly generating two-dimensional codes.
As can be seen from the structure of the intelligent stamp device described in fig. 1, in an embodiment, after the intelligent stamp device receives the stamping behavior identification information, the driving module 104 can drive the movable contact 105 to move according to the stamping behavior identification information, so as to set the stamping behavior identification information on the stamp surface. For example, the driving module 104 may drive the movable contact 105 to move vertically along a direction perpendicular to the surface of the stamp or move horizontally along a direction parallel to the surface of the stamp according to the stamping behavior identification information, so that an image obtained by stamping the moved movable contact 105 on a document is the same as a barcode image corresponding to the received stamping behavior identification information.
After the intelligent seal equipment sets the stamping behavior identification information on the seal surface, a user can stamp a file through the intelligent seal equipment. After the stamping is finished, the intelligent stamping equipment sends the image data of the stamped file corresponding to the stamping behavior to the block chain link points. The stamped file is a file stamped with stamping behavior identification information and user-defined stamping content. The image data of the stamped file can be as shown in the image shown in fig. 3, and includes image data of a stamp portion obtained by stamping the file by the intelligent stamp device, and image data of the file around the stamp portion. As can be seen from the structure of the intelligent stamp device introduced in fig. 1, in an embodiment, a camera in the intelligent stamp device can capture image data of a stamped file after the stamping action is completed, and the communication module can send the image data of the stamped file to the block link points. In other embodiments, the intelligent stamp device further comprises a scanning module, the scanning module can scan the image data of the stamped file after the stamping action is completed, and the communication module can send the image data of the stamped file to the block link points.
Therefore, in step S508, the block link point receives the image data of the stamped file sent by the intelligent stamping device after the stamping operation is completed. The stamped file is a file stamped with stamping behavior identification information and user-defined stamping content.
In the step S510, the block link point stores, in the block chain, the stamping behavior identification information corresponding to the current stamping behavior and the image data of the stamped file corresponding to the current stamping behavior in an associated manner, so as to verify the authenticity of the stamping behavior to be verified.
As can be known from the foregoing description, the stamping request may carry the personnel information of the stamping personnel of the current stamping behavior, and therefore, in an embodiment, in step S510, in the blockchain node, the storing, in the blockchain, the stamping behavior identification information corresponding to the current stamping behavior and the image data of the stamped file corresponding to the current stamping behavior in an association manner includes: and if the personnel information of the stamping personnel of the stamping behavior at this time is matched with the personnel information of the found legal personnel, the block chain link points carry out related storage on the personnel information of the stamping personnel of the stamping behavior at this time, the stamping behavior identification information of the stamping behavior at this time and the image data of the stamped file of the stamping behavior at this time in a block chain.
If the personnel information of the stamping personnel of the stamping behavior at this time is matched with the personnel information of the found legal personnel, the stamping personnel is indicated to be legal personnel, and therefore the personnel information of the stamping personnel of the stamping behavior at this time, the stamping behavior identification information of the stamping behavior at this time and the image data of the stamped file of the stamping behavior at this time are stored in a block chain in a correlation mode by the block chain node, and a stamping event record is formed.
In an embodiment, if the staff information of the seal worker of the current sealing behavior matches the found staff information of the legal staff, before the staff information of the seal worker, the identification information of the sealing behavior, and the image data of the sealed file are stored in the block chain in a correlated manner, the block link point may further: acquiring stamp identification information which is allocated to intelligent stamp equipment in advance; the seal identification information is preset on the seal surface of the intelligent seal device. As shown in fig. 2 and 3, the stamped file is further stamped with stamp identification information.

The foregoing description has been directed to specific embodiments of this disclosure. Other embodiments are within the scope of the following claims. In some cases, the actions or steps recited in the claims may be performed in a different order than in the embodiments and still achieve desirable results. In addition, the processes depicted in the accompanying figures do not necessarily require the particular order shown, or sequential order, to achieve desirable results. In some embodiments, multitasking and parallel processing may also be possible or may be advantageous.
In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Furthermore, nowadays, instead of manually making an Integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Hardware Description Language), traffic, pl (core universal Programming Language), HDCal (jhdware Description Language), lang, Lola, HDL, laspam, hardward Description Language (vhr Description Language), vhal (Hardware Description Language), and vhigh-Language, which are currently used in most common. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.
The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and an embedded microcontroller, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component. Or even means for performing the functions may be regarded as being both a software module for performing the method and a structure within a hardware component.
The systems, devices, modules or units illustrated in the above embodiments may be implemented by a computer chip or an entity, or by a product with certain functions. One typical implementation device is a computer. In particular, the computer may be, for example, a personal computer, a laptop computer, a cellular telephone, a camera phone, a smartphone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.
