Detailed Description
The embodiment of the invention provides an anti-counterfeiting method and device for a seal and an intelligent seal, and aims to solve the problems that the seal is easy to forge and counterfeit, and illegal stamping often occurs.
In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the embodiments described below are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The anti-counterfeiting method of the seal is applied to the intelligent seal with the control module and the spraying device, the control module is arranged in the seal body of the seal, comprises the main control chip and the storage chip, and can execute various data acquisition and processing works, such as acquisition of user operation behavior parameters, comparison of data, control of the switch of the spraying device, setting of spraying pattern information and the like. In addition, various sensors are arranged on the seal body and used for collecting operation behavior parameters of a user.
Referring to fig. 1, a first embodiment of an anti-counterfeiting method for a stamp according to an embodiment of the present invention includes:
101. acquiring operation behavior parameters of a user through a sensor arranged on a seal body;
when a user stamps with the seal, the operation behavior parameters of the user can be acquired through the sensor arranged on the seal body. The operation behavior parameters of the user may include a pressing force degree, a pressing time, a seal grasping position of a finger, and the like when sealing.
Specifically, step 101 may include:
(1) acquiring the position information of fingers when a user holds the seal by an infrared detection device;
(2) acquiring the pressing force degree of the user during stamping through a pressure detection device;
(3) and collecting the pressing time of the stamp body through a timing device.
For step (1), the position information of the fingers of the user when holding the stamp is collected through the infrared detection device, and the infrared detection device can be arranged near the position of the handle of the stamp body. The position information collected by the infrared detection device can be converted into position coordinates, and the position coordinates are sent to a main control chip of the seal control module. For example, a chapter position can be predefined as 0, and when the finger of the user holding the chapter is detected to be in the chapter position, the position coordinate 0 is sent to the main control chip; when detecting that the finger of a user holding the badge is located at the position of the badge body and is 1mm upwards, sending the position coordinate 1 to a main control chip; when detecting that the finger of the user holding the badge is located 1mm below the position of the badge body, sending the position coordinate-1 to the main control chip, and so on.
And (3) for the step (2), detecting the pressing force degree of the user during stamping through a pressure detection device, and sending the obtained pressure information to the main control chip. At the moment when the user stamps the seal, the pressure detection device of the seal head can detect the stamping pressing force of the user and send the obtained pressure information to the main control chip.
For the step (3), a timing device can be arranged in the control module of the stamp, or a timing device can be independently arranged outside the control module, and the timing device is used for collecting the pressing time of the stamp body when the user stamps. When the pressure detection device starts to detect the pressure, the timing device is triggered to start timing, and when the pressure detection device detects that the pressure completely disappears, the timing is stopped, so that the pressing time is obtained.
102. Comparing the collected operation behavior parameters with the standard operation behavior parameters to obtain a comparison result;
after the operation behavior parameters of the user are collected, the collected operation behavior parameters are compared with the standard operation behavior parameters to obtain a comparison result. The standard operation behavior parameters are collected in advance and stored in a memory chip in the seal body, and specifically may be operation behavior parameters when a legal person (such as a seal manager) with a sealing authority seals. During comparison, if the difference value between the collected operation behavior parameters and the standard operation behavior parameters is within a preset range, the comparison result is judged to be successful, otherwise, the comparison result is judged to be failed. In addition, because a plurality of legal persons with stamping authority may exist, and stamping habits of each person are different, a plurality of sets of standard operation behavior parameters can be collected and stored. And during comparison, the obtained operation behavior parameters are respectively compared with each set of standard operation behavior parameters, and the comparison result can be judged to be successful if any set of comparison is successful.
Further, the standard operation behavior parameters include standard position information, standard pressing force and standard stamping time, and step 102 may include:
(1) comparing the position information of the finger when the user holds the seal with the standard position information, comparing the pressing force degree when the user stamps with the standard pressing force degree, and comparing the pressing time of the seal body with the standard stamping time;
(2) if the position information of the finger when the user holds the seal and the standard position information, the pressing force degree and the standard pressing force degree when the user stamps, the pressing time of the seal body and the standard stamping time are successfully compared, judging that the comparison result is successful;
(3) if the comparison between the position information of the finger when the user holds the seal and the standard position information, the pressing strength when the user stamps and the standard pressing strength, the pressing time of the seal body and one of the standard stamping time fails, the comparison result is judged to be the comparison failure.
Everyone has own unique stamp custom, holds the position of the stamp body when stamping, and the degree of pressing and the time of pressing of stamping are generally different from other people. In this embodiment, the acquired 3 kinds of operation behavior parameters are respectively compared with the standard operation behavior parameters, if all comparison is successful, the comparison result is determined to be successful, otherwise, the comparison result is determined to be failed.
Further, the standard operation behavior parameters may be collected in advance through the following steps:
(1) adjusting the seal to a standard parameter acquisition mode;
(2) acquiring operation behavior parameters of each stamping of a target user through the sensor in the process that the target user uses the stamp for stamping for multiple times;
(3) and calculating the average value of the operation behavior parameters stamped by the target user each time, and determining the average value as the standard operation behavior parameter.
And (3) for the step (1), the seal is adjusted to a standard parameter acquisition mode, which is a special working mode and is used for acquiring standard operation behavior parameters. Specifically, the mode adjustment can be implemented by inputting a mode adjustment instruction to a control module of the stamp, for example, setting a mode adjustment key for inputting the instruction.
And (3) for the step (2), the target user, namely a legal person with the stamping authority, uses the stamp to stamp for many times by the target user in a standard parameter acquisition mode, and acquires the operation behavior parameters of each stamping of the target user through the sensor.
And (4) for the step (3), after the operation behavior parameters of the target user for stamping for multiple times are collected, calculating the average value of the operation behavior parameters, taking the average value as the final standard operation behavior parameter, and storing the final standard operation behavior parameter in a storage chip of the stamp control module.
103. If the comparison result is the comparison failure, then use set up in spray device on the chapter body makes the stamp mark makes useless to the preset pattern of stamp mark spraying that covers out.
If the comparison result is that the comparison fails, the user who operates the seal at present is indicated to be not a legal user with the stamping authority, and at the moment, a preset pattern is sprayed on the stamped seal by using the spraying device arranged on the seal body, so that the seal is invalidated. Specifically, the spraying device adopts a programmable small-sized ink-jet printer, and can spray various types of pattern information controlled by computer instructions. In the short time after the user finishes stamping and before the user removes the stamp, if the main control chip of the control module judges that the comparison result is a comparison failure, a control instruction is sent to the spraying device, and a preset pattern (such as a pattern with a word of 'stamping and canceling' is sprayed on the stamped stamp), so that the stamp is canceled.
The anti-counterfeiting method of the seal provided by the embodiment of the invention comprises the following steps: acquiring operation behavior parameters of a user through a sensor arranged on a seal body; comparing the collected operation behavior parameters with standard operation behavior parameters to obtain a comparison result, wherein the standard operation behavior parameters are collected in advance and stored in a storage chip in the chapter body; if the comparison result is the comparison failure, then use set up in spray device on the chapter body makes the stamp mark makes useless to the preset pattern of stamp mark spraying that covers out. In actual operation, the operation behavior parameters of the legal user with the stamping authority can be collected in advance as standard operation behavior parameters. When a certain user stamps with a seal, the operation behavior parameters stamped by the user are compared with the standard operation behavior parameters, if the comparison fails, the user is not a legal user with stamping authority, and at the moment, a preset pattern is sprayed to the stamped seal by using the spraying device, so that the seal is discarded, the problem of illegal stamping is solved, and the frequency of occurrence of false documents and false contracts is effectively reduced.
Referring to fig. 2, a second embodiment of an anti-counterfeit method for a stamp according to an embodiment of the present invention includes:
201. acquiring operation behavior parameters of a user through a sensor arranged on a seal body;
202. comparing the collected operation behavior parameters with the standard operation behavior parameters to obtain a comparison result;
the steps 201-202 are the same as the steps 101-102, and the related description of the steps 101-102 can be referred to.
203. Judging whether the comparison result is successful or failed;
if the comparison result is a successful comparison, step 204 is executed, and if the comparison result is a failed comparison, step 205 is executed.
204. Applying the user's signature and the current time to the stamped stamp using the application device;
and the comparison result is successful, and the current stamping user is a legal user with stamping authority. And at the moment, the signature of the user and the current time are sprayed to the stamped stamp by using the spraying device, so that the stamping is effective. Specifically, the signature information of the user can be collected in advance and stored in a memory chip of the seal control module, and is bound with the standard operation behavior parameters; the seal control module is provided with a clock chip, and can acquire the current time. By such an arrangement, traceability of the stamping information can be further improved (the name of the stamping user and the specific stamping time can be known).
Further, before step 204, the method may further include:
(1) collecting an image of a stamping area by using a camera arranged on the stamp body;
(2) and judging whether the stamping area is a blank area or not according to the image.
The seal body of the seal can be further provided with a camera used for capturing the sealing position, and the image of the sealing area can be better acquired by reasonably adjusting the installation angle and the position of the camera. In practical application, a distance measuring sensor can be arranged on the stamp body at the same time, when a user takes up the stamp, the sensor is triggered to measure the distance between the stamp head of the stamp and the paper surface, and then when the user starts to stamp the stamp, the distance can be gradually reduced; when the distance is detected to be smaller than a certain threshold (such as 2cm), the camera is triggered to collect the image, and the image of the stamping area can be accurately collected. After the image of the stamping area is collected, the image is analyzed, and whether the stamping area is a blank area or not can be judged.
Step 204 may specifically be: and if the stamping area is a blank area, spraying the signature of the user and the current time to the stamped stamp by using the spraying device.
If the stamping area is a blank area, spraying the signature of the user and the current time to the stamped stamp by using the spraying device; and if the stamping area is not a blank area, not executing the spraying operation. In a normal situation, the stamping is generally effective only when the stamping is stamped in a blank area, so that the signature of the user and the current time are sprayed after the stamping area is determined to be the blank area; if the seal is sealed in the non-blank area with the text, the spraying operation is not executed, and the seal is invalid. By such an arrangement, the practicability is further improved.
205. The use set up in spray device on the chapter body makes to the preset pattern of the chapter spraying of covering the chapter mark is useless, and passes through alarm device output alarm information on the chapter body.
The comparison result is the comparison failure, indicates that the user of current operation seal is not the legal user who has the authority of stamping, uses this moment set up in preset pattern is sprayed to the stamp that marks out to spraying device on the stamp body, makes the stamp mark is useless, and passes through alarm device output alarm information on the stamp body. Compared with the step 103, the step 205 can also output alarm information through an alarm device on the stamp body. Specifically, the alarm mode may be a sound-light alarm, a wireless transmission of alarm information to a specific terminal, or other various modes. Through the arrangement, related personnel can be reminded of paying attention to the fact that the seal is stolen by illegal personnel, and emergency treatment measures can be made conveniently in time.
Further, if, before step 205, an image of a seal area is acquired by using a camera disposed on the seal body, step 205 may specifically include:
(1) spraying a preset pattern to the stamping area by using a spraying device arranged on the stamp body;
(2) if the image of the stamping area can not be acquired, the stamping file area is acquired, and the preset pattern is sprayed on the file area by using the spraying device arranged on the stamp body, so that the file is wasted.
The image collected by the camera is positioned to find the seal area of the file, so that the seal can be accurately sprayed to the seal, and the seal is made useless. In addition, if the image of the stamping area can not be acquired, the stamping file area can be acquired at the moment, and a preset pattern is sprayed on the file area by using a spraying device arranged on the stamp body, so that the file is invalidated. Specifically, when an illegal user finishes stamping and moves the stamp away from a stamping area, if the stamp moves above a file area, the stamp can acquire an image of the file area, and at the moment, a spraying device arranged on the stamp body is used for spraying a preset pattern (such as a false file) on the file area, so that the file is invalidated, and the possibility of generating the false file is further reduced.
In this embodiment, when the comparison result is that the comparison is successful, the signature of the user and the current time are sprayed to the stamped stamp by using the spraying device; and when the comparison result is that the comparison fails, alarm information can be output. Compared with the first embodiment of the invention, on one hand, the traceability of the stamping information is improved, and on the other hand, related personnel can be reminded of the abnormal situation of the use of the stamp.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
