The image acquisition module 13 may be configured to shoot a material to be stamped, and obtain a surface image of the material to be stamped, so as to perform authority authentication of a stamping operation by using the surface image.
The communication module is used for establishing communication connection between the electronic stamp device 10 and the user terminal 20 through a network, and for receiving and sending data through the network.
It is understood that the configuration shown in FIG. 1 is merely a schematic configuration of electronic stamp device 10, and that electronic stamp device 10 may also include many more components than those shown in FIG. 1. The components shown in fig. 1 may be implemented in hardware, software, or a combination thereof.
Referring to fig. 2, electronic stamp device 10 may further include a housing 16 and a cover 17. Wherein the housing 16 has a receiving chamber and is open at one end for receiving the locking mechanism 14, the stamp head 15 and other devices (e.g., the processing module 11, the storage module 12, etc.). The opening of which can be used for mounting the stamp head 15 or for taking the stamp head 15. The cover 17 may cover the opening of the case 16. In addition, ink paste may be provided on the side of the cover 17 near the opening so as to adhere a pigment for stamping on the stamp head 15 by the ink paste.
The shell 16 can be provided with one or more cameras, the number of the cameras can be one or more, the cameras can be set according to actual conditions, and the cameras are used for shooting surface images of materials to be stamped so as to obtain first authentication information from the surface images and then verify whether operation permission is provided when the materials to be stamped are stamped through the first authentication information. The material to be stamped can be, but is not limited to, a paper material, a leather material and the like. For example, the document may be a paper contract document, a notice document, a book, a painting and calligraphy work, etc., and is not limited herein.
As an alternative embodiment, the locking mechanism 14 may include a locking tongue 141 and a connecting member 142, and a locking hole 151 may be provided on the handle of the stamp head 15 to be engaged with the locking tongue 141. One end of the connecting element 142 is connected to one end of the casing 16 far away from the opening and fixed on the casing 16, and the other end of the connecting element 142 is provided with a locking tongue 141 which can be driven by electric power to extend and retract. The latch 141 locks the stamp head 15 by being inserted into the locking hole 151, so that the stamp head 15 is not easily taken out.
The connecting member 142 may include an electric telescopic rod and a U-shaped connector 143. One end of the electric telescopic rod is connected with one end of the shell 16 far away from the opening, the other end of the electric telescopic rod is connected with one end of the U-shaped connector 143 far away from the U-shaped opening, and the bolt 141 is arranged on the inner side of the U-shaped opening in the U-shaped connector 143. Understandably, a groove body for the bolt 141 to stretch is arranged on the U-shaped connector 143, a coil for generating a magnetic field can be arranged in the groove body, the bolt 141 can be a magnetic body, different magnetic poles are generated through the coil, and the bolt 141 can be pushed to stretch.
For example, when the coil and the latch 141 have the same magnetic poles at the two ends close to each other, a magnetic force repelling each other is formed, the latch 141 extends out of the groove body, and when the latch 141 is aligned with the locking hole 151, the stamp head 15 can be locked. When the coil and the magnetic poles at the two ends of the bolt 141 close to each other are the same, magnetic force attracting each other can be formed, and the bolt 141 can stretch into the groove body and can be used for unlocking the stamp head 15. The opening of the tank body may be provided with a clamping portion matched with the locking tongue 141, so that after the locking tongue 141 extends out to a certain length (the length may be set according to actual conditions, and is not specifically limited), the locking tongue 141 is clamped, and the locking tongue 141 is prevented from sliding out of the tank body.
In addition, the electric telescopic rod can comprise at least two sections of barrel bodies, and the two or more sections of barrel bodies are sleeved layer by layer and can stretch out and draw back under the action of electric power. When not stamping, electric telescopic handle is in the shrink state, and the stamp head 15 is far away from the one side of connecting piece 142 in casing 16, does not emerge the opening of casing 16, promptly, and the user can't utilize stamp head 15 in the casing 16 to stamp this moment. In the operation process of stamping, replacing the stamp head 15 and taking out the stamp head 15, the electric telescopic rod extends towards the opening part of the shell 16 under the action of electric power, and the one surface of the stamp head 15, which is far away from the connecting piece 142, protrudes out of the opening of the shell 16, so that the operations of stamping, replacing the stamp head 15, taking out the stamp head 15 and the like are realized. The working principle of the electric telescopic rod is well known to those skilled in the art, and the detailed description is omitted here.
Of course, the locking mechanism 14 may have a configuration different from the above-described embodiments, as long as it can lock, unlock, and extend/contract the stamp head 15 under the control of the processing module 11 with the corresponding operation authority. For example, with the corresponding operating authority, the processing module 11 may control the locking mechanism 14 to extend to facilitate mounting or dismounting of the stamp head 15 when mounting the stamp head 15 or dismounting the stamp head 15 from the locking mechanism 14, and then automatically retract after a certain time interval (which may be set according to practical circumstances, for example, 10 seconds, 30 seconds, 1 minute, etc.).
In addition, when the stamp head 15 is removed from the locking mechanism 14 with the authority, the processing module 11 may control the component for locking the stamp head 15 in the locking mechanism 14 to unlock so as to release the stamp head 15, and when the stamp head 15 is installed, the processing module 11 may control the component for locking the stamp head 15 in the locking mechanism 14 to lock the stamp head 15 so as to prevent the stamp head 15 from being easily taken out. When the stamping authority is present, the processing module 11 may control the locking mechanism 14 to extend so as to stamp the material to be stamped.
The principle of the electronic seal device 10 for operation authority authentication may refer to the following detailed description of the seal processing method, which is not described herein again.
Referring to fig. 4, an embodiment of the present application further provides a stamping processing method, which can be applied to the electronic stamping device 10. The material to be stamped needs to have stamp information of the designated electronic stamp and a stamp pattern of the entity stamp at the same time to be considered as the signature to be effective. The seal processing method may include steps S210 to S230.
Step S210, acquiring a surface image of a material to be stamped through an image acquisition module 13 in the electronic stamp device 10;
step S220, carrying out image recognition on the surface image to judge whether first authentication information matched with first preset authentication information exists in the surface image, wherein the first preset authentication information comprises seal information of a specified electronic seal printed on the material to be sealed in advance;
step S230, when first authentication information matching the first preset authentication information exists in the surface image, controlling the stamp head 15 in the electronic stamp device 10 to stamp on the material to be stamped.
In the above embodiment, when the material to be stamped needs to be stamped, a designated electronic stamp needs to be printed on the material to be stamped in advance, and when the material to be stamped has the designated electronic stamp, the material to be stamped prints a physical stamp by the stamp head 15. The stamp head 15 is deposited in the electronic stamp device 10, when the stamp head 15 is needed to be used for stamping, the electronic stamp device 10 authenticates a material to be stamped, and stamps after the authentication is matched, so that the authority level of stamping operation is improved, stamping on the material which is not authenticated is avoided, and the problem that safety risk exists in the management and the use of entity stamping is solved.
The steps of the stamping processing method shown in fig. 4 will be described in detail below:
step S210, acquiring a surface image of the material to be stamped by the image acquisition module 13 in the electronic stamp device 10.
In this embodiment, when a material to be stamped needs to be stamped, an operator may place the electronic stamping device 10 in an area where the material to be stamped needs to be stamped, where an opening of the electronic stamping device 10 is tightly attached to the material to be stamped. At this time, the shooting angle of view of the image capture module 13 in the electronic seal device 10 is directed toward the surface of the material to be sealed, so that the surface image of the material to be sealed can be acquired.
Understandably, assuming that the material to be stamped is printed with stamp information of a specified electronic stamp, the electronic stamp device 10 does not obscure the stamp information when the electronic stamp device 10 is used. The viewing angle of image capture module 13 may be fixed relative to housing 16 of electronic stamp device 10 or may be manually adjustable (i.e., image capture module 13 may be rotatably disposed on housing 16). When shooting the surface image, the placement position of the electronic stamp device 10 may be adjusted by the user so that the image acquisition module 13 can shoot the stamp information on the material to be stamped. Or, the shooting angle of view of the image capturing module 13 is manually adjusted, so that the image capturing module 13 can shoot the seal information on the material to be sealed.
Step S220, performing image recognition on the surface image to determine whether first authentication information matching first preset authentication information exists in the surface image, where the first preset authentication information includes seal information of a designated electronic seal printed in advance on the material to be sealed.
In this embodiment, the processing module 11 of the electronic seal device 10 may perform image recognition on the captured surface image to determine whether the first authentication information matching the first preset authentication information exists in the surface image. The seal information of the designated electronic seal can be the seal image of the designated electronic seal, and can be set according to actual conditions.
Understandably, in the present embodiment, under a normal signature process, before the physical seal of the seal head 15 is printed on the material to be stamped, the seal information of the designated electronic seal needs to be printed on the material to be stamped, and at the same time, the seal information of the designated electronic seal is sent to the electronic seal device 10 (the seal information may be sent to the electronic seal device 10 by the user terminal 20) to serve as the first preset authentication information. For example, if the material to be stamped is a contract document, when the contract document is printed, a person with management authority may sign seal information of a designated electronic seal on the contract document of the electronic version, and then print the seal information of the designated electronic seal. Of course, the seal information can be printed after the contract document is printed. Namely, the seal information of the designated electronic seal needs to be electronically signed on the material to be sealed by a person with management authority, and based on this, the designated electronic seal can be prevented from being optionally stamped on the material to be sealed, thereby improving the security of the stamping process.
As an alternative embodiment, the stamp information includes a stamp image of the designated electronic stamp, and step S220 may include: judging whether a seal image exists in the surface image or not based on the image characteristics of the surface image, wherein the similarity between the seal image and the seal image of the appointed electronic seal is greater than or equal to an appointed threshold value; and when the seal image exists in the surface image and the similarity between the seal image and the seal image of the appointed electronic seal is larger than or equal to an appointed threshold value, determining that the first authentication information matched with the first preset authentication information exists in the surface image.
In this embodiment, the processing module 11 may extract image features of all surface images currently acquired by the electronic stamp device 10 (if the image acquisition module 13 is one, the acquired surface image is one image, and if the image acquisition modules 13 are two or more, the acquired surface images are two or more images), so as to preliminarily determine whether the stamp image exists in the surface image. And when the seal information exists, further judging the similarity between the seal image and the seal image of the appointed electronic seal, thereby determining whether the current sealing operation passes the authentication.
And when the seal image exists in one or more surface images and the similarity between the seal image and the seal image of the appointed electronic seal is greater than or equal to an appointed threshold value, the surface image is considered to have the first authentication information matched with the first preset authentication information, namely the authentication is passed. The specified threshold may be set according to actual conditions, and may be, for example, 90%, 95%, 99%, or the like.
And when the seal images do not exist in all the surface images, the surface images are considered to have no first authentication information matched with the first preset authentication information, and the seal operation is not authenticated. And when the seal image exists in one or more surface images, but the similarity between the seal image and the seal image of the appointed electronic seal is smaller than an appointed threshold value, the first authentication information matched with the first preset authentication information does not exist in the surface image, and the authentication of the sealing operation is not passed.
The image features extracted by the processing module 11 include, but are not limited to, texture features of the image, HOG (histogram of Oriented gradients) features, and the like.
In calculating the similarity of the seal images, the processing module 11 may compare the degree of coincidence of the seal line (which may be referred to as a standard seal line) of the seal image of the designated electronic seal with the seal line in the surface image. That is, the processing module 11 may convert the seal lines in the surface image into seal lines at the same viewing angle as the seal lines of the seal image; and then scaling the seal lines to ensure that the size of the converted seal lines is the same as that of the standard seal lines, overlapping, rotating the overlapped seal lines, and calculating the maximum contact ratio of the converted seal lines and the standard seal lines in the rotating process. The maximum contact ratio is the similarity between the seal image of the designated electronic seal and the seal image in the surface image.
As an optional implementation manner, the first preset authentication information (or the seal information of the designated electronic seal) includes preset encoded information carrying identity information representing the designated electronic seal, where the preset encoded information includes at least one of a two-dimensional code, a barcode, and a character code, and step S220 may include: judging whether the surface image has coding information or not based on the image characteristics of the surface image; when the coded information exists in the surface image, analyzing target information carried by the coded information; judging whether the target information is the same as the identity information carried by the preset coding information or not; when the target information is the same as the identity information, determining that the first authentication information matched with the first preset authentication information exists in the surface image.
In this embodiment, if the first predetermined authentication information is the predetermined encoding information. The processing module 11 may first preliminarily determine whether the coded information exists on the surface image through image recognition, and then determine whether the coded information is the same as the preset coded information when the coded information exists. If the two are the same, the authentication of the stamping operation is considered to pass, and if the two are not the same, the authentication is not passed.
The preset coding information can be set according to actual conditions, namely, the two-dimensional code, the bar code and the character code can be set according to actual conditions. For example, the preset encoding information is character encoding, and the character encoding may be a numeric string. Or the preset coding information is a two-dimensional code or a digit analyzed by the two-dimensional code.
Understandably, in a normal stamping process, before the material to be stamped is stamped with the physical seal of the stamping head 15, the encoded information needs to be stamped, and the encoded information also serves as the preset encoded information, and can be sent to the electronic stamping device 10 by the user terminal 20 to be stored, so as to serve as the first preset authentication information. When the electronic seal device 10 is used, the encoded information parsed from the surface image of the material to be sealed facilitates the first predetermined authentication information being the same, and the authentication of the sealing operation is passed.
As an alternative implementation, the first preset information may include seal information and preset encoding information of the designated electronic seal. Step S220 may include authenticating the stamp image, then authenticating the encoded information, and considering that the stamp operation is authenticated only when both authentications are passed.
Step S230, when first authentication information matching the first preset authentication information exists in the surface image, controlling the stamp head 15 in the electronic stamp device 10 to stamp on the material to be stamped.
In the present embodiment, when there is first authentication information that matches the first preset authentication information in the surface image, it is considered that the authentication for the stamping operation to be currently performed passes. When the authentication of the stamping operation is passed, the electronic stamping device 10 drives the stamping head 15 to stamp the material to be stamped. After stamping is complete, the electronic stamping device 10 may automatically retract the stamping head 15 into the housing 16. For example, after the print head is controlled to extend for a period of time, the stamping is considered to be completed, and the period of time can be set according to actual conditions, and can be 30 seconds, 1 minute and the like.
In this embodiment, the locking mechanism 14 in the electronic stamp device 10 may include a connecting member 142 for driving the stamp head 15 to stretch, the handle portion of the stamp head 15 is connected to one end of the connecting member 142, the other end of the connecting member 142 is connected to the housing 16 of the electronic stamp device 10, and the step S230 may further include: when the first authentication information matches the first preset authentication information, the control connecting member 142 (e.g., an electric telescopic rod) is extended to make the stamp head 15 protrude out of the opening portion of the housing 16, so as to stamp on the material to be stamped.
As an optional implementation, the method may further include: when an instruction for replacing the stamp head 15 is received, acquiring second authentication information for replacing or taking out the stamp head 15 within a first preset time length after the instruction is received; judging whether the first authentication information is the same as the current second preset authentication information or not; and when the second authentication information is the same as the current second preset authentication information, controlling the locking mechanism 14 in the electronic stamp device 10 to unlock the stamp head 15. The first preset time period may be set according to actual conditions, and may be 1 minute, 10 minutes, and the like.
In the embodiment, the time for acquiring the authentication information is limited, so that the timeliness of the authentication is improved. The second authentication information may be obtained by the image capturing module 13 capturing information provided by a user (including but not limited to a manager, a stamping person, or other person). Alternatively, the numbers input by the stamping person from a keyboard (which may be a touch screen or a numeric keyboard) of the electronic stamping device 10 are used as the second authentication information. The content of the second preset authentication information can be set according to actual conditions.
In the present embodiment, the stamp head 15 is generally kept by a person having administrative authority. When receiving an application for changing the stamp head 15 from an operator (usually, a person who keeps the stamp head 15), a manager (the manager may be the same person as the person who keeps the stamp head 15, or may be different from the person who keeps the stamp head 15) sends second preset authentication information to the electronic stamp device 10 through the user terminal 20, and provides the second preset authentication information to an operator as second authentication information, so that the operator can perform authentication conveniently. At this time, the transmitted second preset authentication information may be used as an instruction for replacing the stamp head 15. Of course, the instruction may be received by electronic stamp device 10 in other ways as well. For example, the generation is triggered by an operator via a button in electronic stamp device 10 having the function of replacing stamp head 15. In addition, electronic stamp device 10 may record the interval duration from the current time when the instruction is received.
As an optional implementation, the method may further include: after the second preset time length after the instruction is received, or the time length of the existence of the second preset authentication information stored in the electronic seal device 10 is greater than or equal to a fourth preset time length, controlling the second preset authentication information to be invalid, wherein the second preset time length is greater than the first preset time length. The second preset time length and the fourth preset time length can be set according to actual conditions.
Understandably, the operator is typically required to complete the seal head 15 replacement operation within a second predetermined length of time. When the second preset duration is exceeded, the electronic stamp device 10 may issue an alarm prompt when detecting that the locking mechanism 14 is not equipped with the stamp head 15, and at the same time, control the second preset authentication information to be invalid. When it is necessary to install the stamp head 15 again, it is necessary to transmit new second preset authentication information to the electronic stamp device 10 by the user terminal 20 again and to perform authentication again. In other words, by dynamic authentication and limiting the effective time of authentication, it is helpful to improve the timeliness and security of authentication.
As an optional implementation, the method may further include: and controlling the first preset authentication information to be invalid when a third preset time length after the seal information of the appointed electronic seal is printed on the material to be stamped or when a time length of the first preset authentication information stored in the electronic seal device 10 is greater than or equal to a fifth preset time length.
In the above embodiment, after a period of time after the seal is completed, by controlling the first preset authentication information to be invalid, the person is prevented from repeatedly performing authentication by using the first authentication information matched with the first preset authentication information, thereby contributing to improvement of the security of the authentication. Or, when the first preset authentication information exists for a period of time, the first preset authentication information is automatically invalid. That is, the electronic stamp device 10 needs to dynamically set the first preset authentication information, and is helpful to improve the timeliness and safety of authentication through dynamic authentication. The third preset time length and the fifth preset time length can be set according to actual conditions.
For example, after the stamp information is printed on the material to be stamped, the first preset authentication information is invalidated immediately or one minute later. Or, if the time length of the first preset authentication information stored on the electronic seal device 10 exceeds the time length of 1 hour, 24 hours, etc., the first preset authentication information is automatically invalidated.
As an optional implementation, the method may further include: detecting whether the stamp head 15 is locked in the locking mechanism 14 in the electronic stamp device 10; when the seal head 15 is not locked by the locking mechanism 14, a prompt message is issued or issued to a specified terminal. The designated terminal may be a user terminal 20 held by a manager. The manner of sending out the prompt information can be but is not limited to text prompt, sound prompt, light prompt and the like, and can be set according to actual conditions.
In the above-described embodiment, the prompt message is given to help the manager know in time that the seal head 15 is not locked by the locking mechanism 14, thereby helping the manager know in time the condition of the seal head 15.
In this embodiment, the power supply of the electronic stamp device 10 may be a commercial power, or the electronic stamp device 10 may include a power module itself, or the power supply of the electronic stamp device 10 may be provided by the commercial power, or may be provided by the power module itself. When the electronic stamp device 10 does not require a stamping operation, an operation of mounting/dismounting the stamp head 15, the locking mechanism 14 can maintain the locking of the stamp head 15 (for example, the locking mechanism 14 can still lock the stamp head 15 without power supply) to prevent the stamp head 15 from being easily taken out.
The present application further provides a stamping verification method, which is applied to electronic devices, such as but not limited to smart phones, personal computers, electronic stamping devices 10, and the like, and can verify a stamp image and authentication information formed on a material (material to be stamped) by the stamping processing method in the above embodiments. The seal verification method may include:
acquiring a surface image of a material to be verified through an image acquisition module, wherein the image acquisition module comprises a camera or an image sensor;
carrying out image recognition on the surface image to judge whether a seal image exists in the surface image or not and to judge authentication information;
when the seal image and the authentication information exist, judging whether the seal image is matched with the authentication information or not and whether the authentication information is matched with first preset authentication information or not, wherein the first preset authentication information comprises seal information of a designated electronic seal printed on the material to be verified in advance, and the designated electronic seal is associated with a seal corresponding to the seal image;
when the authentication information is matched with the stamp image and the stamp image is matched with the first preset authentication information, determining that the material to be verified passes verification;
and when the authentication information does not exist, or the authentication information is not matched with the stamp image, or the authentication information is not matched with the first preset authentication information, determining that the material to be verified is not verified.
In this embodiment, the electronic seal and the physical seal printed on the material to be stamped can be authenticated in real time to identify the authenticity of the material. When the electronic seal and the physical seal are both corresponding assigned seals, the signature is valid. A corresponding relationship (or an association relationship, a mapping relationship) may be pre-established between the electronic seal (authentication information) and the entity seal (seal image), and when the corresponding relationship exists between the electronic seal and the entity seal in the material to be verified, it indicates that the electronic seal is matched with the entity seal. The electronic device performing the verification operation may be the electronic stamp device 10 or another device (such as a server, a smartphone), and is not particularly limited herein.
As an alternative implementation, the authentication information may be a two-dimensional code. In the image identification process, the electronic equipment can search information such as whether a seal image exists on a surface image or not and whether a two-dimensional code exists or not, if the seal image and the two-dimensional code exist, the electronic equipment can judge whether a preset corresponding relation exists between the seal image and the two-dimensional code or not, if the preset corresponding relation exists, the seal image is considered to be matched with the two-dimensional code, whether the two-dimensional code is the preset two-dimensional code or not is further judged, and if the two-dimensional code is the preset two-dimensional code, the seal authentication of a material to be verified is considered to be passed. If the preset corresponding relation does not exist between the stamp image and the two-dimensional code, the stamp image is not matched with the two-dimensional code, and the stamp authentication of the material to be verified is not passed. If the two-dimensional code does not exist, the seal authentication of the material to be verified is not passed.
It should be noted that the authentication operation on the first authentication information and the second authentication information may be performed by the server. The server may store the first preset authentication information and the second preset authentication information, and may perform data interaction with the user terminal 20 and the electronic seal device 10. The electronic seal device 10 may transmit the first authentication information (or the surface image of the material to be sealed), the second authentication information to the server. After the server completes authentication, it may send the authentication result (including authentication pass or fail) to the electronic stamp device 10, and the electronic stamp device 10 responds based on the authentication result. For example, upon authentication of the stamping operation, the electronic stamping device 10 controls the latching mechanism 14 to move the stamping head 15 to stamp the material to be stamped.
In addition, in the present embodiment, the physical seal and the electronic seal (seal information specifying the electronic seal) need to exist simultaneously on the material to be sealed to consider the signature valid. In the process of the seal authorization, an administrator with authority needs to seal the material to be sealed with an electronic seal first, and then perform the physical seal authorization (that is, the user terminal 20 sends the first preset authentication information to the electronic seal device 10), and then other personnel perform the operation of sealing the physical seal through the electronic seal device 10. In the process of stamping the physical seal, the electronic seal device 10 may scan the electronic seal to perform authenticity authentication, and stamp the physical seal when the authentication passes. In addition, before the physical seal is applied, the operator needs to apply the right of use of the electronic seal device 10 from the manager. Before applying for the right of use, the operation of applying the electronic seal (namely, the seal information of the appointed electronic seal needs to be printed on the material to be stamped) needs to be applied to a manager, and after the application of the electronic seal is completed, the application flow of the right of use of the electronic seal equipment 10 can be carried out, so that the electronic seal equipment 10 is prevented from being stolen, the safety level of management and use of the entity seal is improved, and the risk of managing and using the entity seal is reduced.
