Description

Implementation method of paper-based visual recognition anti-counterfeiting electronic seal Technical Field

[0001] The invention relates to an implementation method of a paper-based visual recognition anti-counterfeiting electronic seal. Background Art

[0002] In the internet economy, remote contract signing is a common economic practice. Scenarios requiring remote unilateral seals are also common, such as when tender documents require on-site revisions and stamping, when inquiries are submitted at the bid opening, and when letters of introduction are issued remotely. Physical seals present numerous management challenges and loopholes, are ill-suited to remote seal affixing, and carry significant legal and financial risks. Examples include the media-publicized incidents of fake seals used by a certain godmother and a certain news site, the official seal snatching incident at a certain website, and the counterfeiting of a certain company's official seal by a certain Yadi company. Seal custodians also frequently abuse, steal, or even blank seals. Once seals are taken away, monitoring their use becomes difficult. Seals of subordinate units are difficult to supervise, and any illegal use of seals can lead to unnecessary legal liability and financial losses for the superior unit. When seals must be mailed remotely, the costs are high, efficiency is low, and there is a risk of loss. The remote contract signing process is inconvenient and difficult to standardize. Currently, a common method involves one party scanning a stamped document and sending it to the other party, who then prints the scanned document, stamps it, scans it again, and sends it back. This process is cumbersome, and the multiple scans often result in poor document quality. This, along with the challenges of electronically managing stamped documents, is another pain point in managing physical seals.

[0003] In recent years, products like smart seal machines have emerged. These place a physical seal inside a remotely controlled smart housing with a built-in IoT chip. The housing can only be opened with remote authorization to affix the seal, and the machine automatically captures a photo of the stamped text. While these smart seal machines address challenges such as remote stamping and seal management for branches and subsidiaries, they remain cumbersome to operate and carry, and they still don't address the issue of seal forgery.

[0004] In the era of physical seals, there was also a practice of using text or graphic software to counterfeit the electronic image of a physical seal. This electronic seal image was then applied to documents such as WPS or Word, and then printed out as a paper document using a color printer. This practice was essentially an illegal counterfeiting of various seals. These were generally not used independently as electronic documents, but were mostly printed out as paper documents and used as impersonators. The authenticity of these illegally counterfeited electronic seals was generally determined by distinguishing subtle differences between the printed color of the seal and the color of the ink used to seal it. When color discrimination was impossible, background checks on the stamped text were often required to verify its authenticity. The reason this simple electronic seal counterfeiting practice became a widespread problem was that it lacked visual anti-counterfeiting features or authoritative certification from third-party platforms to prevent its abuse. On the other hand, if a third-party-certified electronic seal image is merely a replica of a physical seal image, lacking the dynamic visual information and convenient anti-counterfeiting authentication features of a true anti-counterfeiting electronic seal, such an electronic seal image will still be difficult to transfer to a printed document for circulation and use. This is because the seal images on printed paper documents are uniformly identical, making it difficult to distinguish the authenticity of the seal image and the stamped text. This forces users to resort to complex electronic authentication platforms. Internet applications emphasize user-friendly and convenient operation, but the electronic authentication methods of existing online signing platforms are extremely complex, and the complex authentication process discourages many novice users.

[0005] With the development of internet technology, social and economic life requires electronic signatures to address these issues. Thus, electronic signatures and online identity authentication emerged. In 1995, the US state of Utah enacted the world's first electronic signature law; in 1996, the United Nations Commission on International Trade Law (UNCITRAL) developed the "Model Law on Electronic Signatures"; in 1999, the European Union adopted the "Electronic Signatures Directive"; in 2000, the US Congress passed the "Electronic Signatures in Global and National Commerce Law Act," which President Clinton electronically signed. Subsequently, over 40 countries, including Japan, Singapore, and South Korea, also enacted laws related to e-commerce. On April 1, 2005, my country's "Electronic Signature Law" officially came into effect. On April 2, 2003, DocuSign was incorporated in Washington State to provide electronic signature solutions.

[0006] In 2006, the inventor published "Dual-Network Wireless Seal Authentication" in the 9th issue of Electronic Commerce magazine that year. This paper first proposed using SMS dynamic codes to solve the problem of remote identity authentication, a technology that has now been widely used. This technical approach forms one of the theoretical foundations of the present invention's electronic seal anti-counterfeiting authentication.

[0007] Since 2010, over a dozen online platforms in China have launched third-party online contract signing services, including Shangshangqian, FaDaDa, Contract Lock, Cloud Contract, E-Sign, Yiyunzhang, Wotong WoSign, China Cloud Sign, Anxinqian, No. 1Sign, Wenqian, Lingqian, Yiqiantong, and Sign Pen Box. Many organizations, such as banks, mobile companies, and customs, also provide external access to electronic seals for signatures or documents. However, the electronic seals used by these platforms or organizations only provide electronic security features, not paper-based security. These seals retain the same design each time they are used, making them easily copied without detection.

[0008] The currently available electronic seal services are essentially semi-functional electronic seals provided by the aforementioned online contract signing platforms. These electronic seals are merely ancillary products offered by online contract signing platforms, providing only electronic security features and lacking visual or paper-based security. These electronic seals can only be attached to electronic documents in specific formats (typically PDFs). When printed on paper or displayed as images on electronic displays (such as web pages), these seals completely lose their security features. This is a key pain point in the current use of online contract signing and electronic seals. Because existing electronic seals for online contract signing lack the same paper-based security features, their daily use is subject to numerous limitations, particularly among small and medium-sized enterprises and individual businesses, which have very low acceptance of online contract signing. As of January 2023, there were over 150 million registered industrial and commercial entities in China, including over 50 million incorporated enterprises. However, the cumulative number of industrial and commercial entity users of online contract signing remains in the millions, with a penetration rate of only around 5%. The existing online signing service is essentially a value-added service of electronic seals.

[0009] Currently, there's a widespread view in the industry that the future will inevitably be completely paperless. In the trend toward electronic office work, addressing electronic documents as long as they address anti-counterfeiting issues at the electronic level effectively resolves all anti-counterfeiting issues, and electronic seals don't require paper-based anti-counterfeiting features. In fact, it's precisely this widespread acceptance that has led to the aforementioned signing platforms paying little attention to visual anti-counterfeiting issues in the electronic signature field—in essence, this is due to the lack of an effective solution. The inventors believe that both this prediction and this conclusion are inaccurate. First, a completely paperless office won't become a reality in the foreseeable future. In fact, many online signing service providers also offer smart seal machines, demonstrating that paper-based stamped documents remain a rigid demand. Second, even for electronic documents, visual verification of authenticity remains essential during use, and its frequency of use will far exceed that of electronic authentication. Furthermore, a significant portion of the industry even believes that paper-based anti-counterfeiting for electronic seals is impossible. This biased perception can only be overcome with the development of truly practical technical solutions. Of course, others in the industry are diligently exploring visual (paper-based) anti-counterfeiting technologies for electronic seals. Existing visual anti-counterfeiting technologies for electronic seals primarily rely on special watermarks, special patterns, special inks, or specialized printers. However, these methods inherently carry the potential for duplication or imitation. Furthermore, since external verification parties often lack knowledge of the original seal's texture or ink standards, verifying authenticity is difficult.

[0010] Therefore, in real social and economic life, there is an urgent need for a full-featured electronic seal to replace physical seals, enhance the current online signing seal function, and cover all scenarios of online and offline applications. Whether this goal can be achieved cannot be easily confirmed or denied until a real solution is implemented.

[0011] In the "Smart Seal System" solution, CN104850961A (2015102921354), published on August 19, 2015, the system obtains information about the issuing entity and the recipient by scanning a QR code. This solution, which adds the recipient information to the QR code, lacks visual recognition capabilities. In fact, using a QR code alone offers no anti-counterfeiting capabilities. This is because it's extremely easy to generate information and a QR code, and the authenticity of the code cannot be visually verified. The recipient information in this solution is simply displayed, making it easily copied and forged. Furthermore, if forged, there's no convenient anti-counterfeiting verification method.

[0012] CN106682479A (2016111909765), "An Electronic Seal System and Method of Use," published on May 17, 2017, states: After review, the user agrees to authorize the application and provides information such as the contract number or document number, the number of stamps, and the number of copies. The seal is then formed into a seal by the seal forming module and transmitted to the electronic seal key. At this point, the text file is stored in the electronic seal key memory. The electronic seal key will appear as a password seal on the document stamped with the seal, along with the legal person's password seal. The seal is then stamped in an appropriate location on the last page of the contract or document. CN109840704A (201910080554X), "An Intelligent Seal Management System," published on June 4, 2019, discloses the use of a cloud platform to record and store seal usage time and frequency for easy user query. Two applications, 2021101930440 and 202110190817X, published on May 7, 2021, address the issue of visual anti-counterfeiting for electronic seals. These two technical solutions incorporate the time information and cumulative number of electronic seal affixing times into the electronic seal image. These solutions only address the uniqueness of each electronic seal affixing, but they still fail to address the electronic seal's directionality and the crucial issue of anti-counterfeiting authentication.

[0013] The inventors believe that a seal represents an organization or an individual, and it possesses both intrinsic and extrinsic characteristics. The seal pattern is equivalent to a person's appearance; the seal images or stamp samples stored on third-party platforms are equivalent to the ID card data stored by public security agencies; and the electronic signature or identity authentication data is the DNA of an anti-counterfeiting electronic seal. Existing technical solutions have effectively addressed the issues of data storage and DNA, but they have not addressed the issue of visually identifying the seal pattern, and naturally, the paper-based anti-counterfeiting problem of electronic seals. In practical applications, however, visual identification of patterns is universal and in high demand. Just as between people, daily identification relies on appearance, only in a few special circumstances is it possible to compare ID cards based on authority, and only in even more exceptional circumstances is DNA comparison possible. The inventors believe that despite over 20 years of its existence, electronic signatures remain largely unadopted and unacceptable. The core reason for this is the lack of a solution to the problem of visual identification, creating an insurmountable gap between them and the general public. Both electronic and visual anti-counterfeiting are essential. Existing third-party signing platforms only solve one of these problems.

[0014] Generally speaking, electronic seal anti-counterfeiting mainly involves four aspects: first, the identity authentication of the seal subject, which is solved through reliable identity authentication on a third-party platform; second, the authenticity of the seal image itself, which is solved at multiple levels through a combination of visual anti-counterfeiting seal patterns and electronic anti-counterfeiting methods on the platform, corresponding to the anti-counterfeiting authentication requirements at different levels; third, the uniqueness, directionality, and anti-illegal counterfeiting and copying of the electronic seal, text content, and the counterparty, which can also be solved at multiple levels through a combination of visual anti-counterfeiting seal patterns and electronic anti-counterfeiting methods on the platform, corresponding to the anti-counterfeiting authentication requirements at different levels; fourth, the reliable and convenient anti-counterfeiting authentication of external stakeholders. Only by rationally combining the above four aspects can a truly practical and easy-to-manage anti-counterfeiting electronic seal be created. Summary of the Invention

[0015] In view of the use and anti-counterfeiting problems of electronic seals in the network economy era, the purpose of the present invention is to provide a reliable and convenient implementation method of paper-based visual identification anti-counterfeiting electronic seals.

[0016] To achieve this purpose, the implementation method of the paper-based visual recognition anti-counterfeiting electronic seal of the present invention is realized through electronic seal function software. When the user needs to stamp, the seal pattern is generated by operating the electronic seal function software and stamped on the electronic text to be stamped. The seal pattern of the paper-based visual recognition anti-counterfeiting electronic seal includes a fixed information unit and a dynamic information unit; the fixed information unit includes a combination of one or more of the following information: seal body name, seal logo, seal body code or seal type name; it is characterized in that: the dynamic information unit includes an authorized counterparty association code; the authorized counterparty association code is generated by the following method: the electronic seal operator submits the authorized counterparty's communication tool number information to the electronic seal function software; the electronic seal function software selects part or all of the above-mentioned submitted authorized counterparty communication tool number information to constitute part or all of the content of the authorized counterparty association code, and solidifies the authorized counterparty association code in a directly visually readable manner in the generated seal pattern or its attached information area.

[0017] A preferred solution is that the communication tool number is a communication tool number with unique identity-binding properties, including mobile phone numbers, email addresses, or instant messaging software numbers. Mobile phone numbers are the most reliable and convenient solution for anti-counterfeiting authentication. Instant messaging software numbers include WeChat, QQ, and MSN accounts. Communication tool numbers with unique identity-binding properties refer to those that are bound to a certain degree of unique identity by the number holder or user, including those that have undergone real-name authentication, such as mobile phone numbers, email addresses, QQ, and WeChat. These communication tool numbers have relatively stable and clear identity-binding properties and can be used with mobile devices, making them portable. Landline phone numbers, on the other hand, do not qualify as communication tool numbers with unique identity-binding properties. This is because the number of people using a particular landline number is often unpredictable, making it relatively inaccurate and susceptible to malicious exploitation when used for user identity authentication. Furthermore, most are not portable. While the PHS system of years ago was portable, its binding to a landline phone made its identity-binding properties unstable.

[0018] The preferred solution is that the information in the auxiliary information area is generated and displayed synchronously with the main pattern of the seal, and can be printed on paper synchronously. The main pattern of the seal refers to the part of the pattern that contains the main body-related characteristic information such as the name of the seal body, the code of the seal body or the type of seal according to traditional usage habits. The preferred solution is that the auxiliary information area is a rectangular information area, an annular information area outside the circular or elliptical seal main pattern circle, or an irregular amorphous information area. Generally speaking, the auxiliary information area is located outside the main pattern information area, and the closest distance between the auxiliary information area and the main pattern information area is less than or equal to the diameter of the main pattern information area, or the closest distance between the auxiliary information area and the main pattern information area is less than or equal to the length of the widest part of the outline of the main pattern information area. The dynamic information unit can also include two or more groups of authorized counterparty association codes.

[0019] Furthermore, the electronic seal function software retains the seal pattern sample, seal information summary or seal text formed after the stamping operation, and the seal pattern sample, seal information summary or seal text are collectively referred to as seal samples; the electronic seal function software is configured with an electronic seal authentication communication interface; the electronic seal function software will authenticate and associate the communication tool number that serves as the source of the authorized counterparty's associated code information with the seal sample, or the electronic seal function software will authenticate and associate the obtained communication tool number information of the authorized counterparty with the seal sample; the electronic seal function software grants the authorized counterparty the right to actively initiate authentication, extraction or review for this or this batch of seal samples by identifying the authentication-associated communication tool number information used by the authorized counterparty.

[0020] The proactive authentication, retrieval, or review rights described above differ fundamentally from the online contract notification SMS messages currently sent by online contract platforms to contracting parties, primarily in the following respects. First, their functions and purposes differ: existing contract notification SMS messages are used to notify contracting parties to complete online contract signing; whereas, the proactive authentication, retrieval, or review capabilities proposed in this invention are primarily intended for authenticity verification. Second, their operational processes differ: existing online contract notification SMS messages are generated and sent by the contracting party, notifying them to proceed online, with the contracting party passively or actively receiving and responding to these operations; whereas, the proactive authentication, retrieval, or review capabilities proposed in this invention are initiated by the authorized party at any time, with the platform then granting or denying the request. Having proactive anti-counterfeiting authentication is a fundamental requirement for digital anti-counterfeiting authentication. Third, their anti-counterfeiting effectiveness differs: proactive authentication, retrieval, or review capabilities provide authorized parties with proactive anti-counterfeiting authentication against stamped samples, making counterfeiting impossible. However, the mobile phone number receiving the existing contract notification SMS message is not associated with the stamped text for authentication, and therefore, lacks the autonomous anti-counterfeiting capability of the counterparty. Fourth, existing contract notification SMS messages cannot extract the text of a single party's seal. When the counterparty receives the contract SMS but does not sign, the contract process remains suspended, unable to proceed to the next step. The solution of the present invention enables the counterparty to independently and proactively authenticate, extract, or review single, double, or multiple party seal samples. Fifth, and most critically, the recipient's mobile phone number in existing contract notification SMS messages is not included in the seal image or the accompanying information area. As a result, existing electronic seals have neither directionality nor offline verifiability, and lack the anti-counterfeiting function of paper-based seals.

[0021] Furthermore, the method for authenticating, extracting or reviewing the seal sample is: the authorized counterparty uses or operates the communication tool number associated with the seal sample authentication or the communication tool number serving as the basis for the authorized counterparty's associated code information, establishes communication contact with the electronic seal function software through the electronic seal authentication communication interface, and makes a request for authentication, extraction or review of the seal sample; after receiving the above request, the electronic seal function software extracts the communication tool number information requested by the authorized counterparty, determines whether there is a seal sample associated with the number information authentication, and thus decides whether to grant its request.

[0022] A preferred solution is that the dynamic information unit also includes a seal sample association code, and the seal sample association code is generated according to the following method: during the electronic seal stamping operation, the electronic seal function software automatically generates the seal sample association code during the stamping operation, and solidifies the generated seal sample association code in a directly visually readable form and presents it in the generated seal pattern. Alternatively, the electronic seal function software obtains the time information during the stamping operation, and solidifies the obtained time information in a directly visually readable form and presents it in the generated seal pattern, constituting part or all of the content of the dynamic information unit. One of the preferred solutions is that the electronic seal function software uses the obtained time information as the basic information for generating the seal sample association code. Another preferred solution is that the time information during the stamping operation and the seal sample association code are simultaneously solidified in a directly visually readable form and present in the generated seal pattern, constituting part or all of the content of the dynamic information unit.

[0023] The preferred method for authenticating, extracting or reviewing a seal sample is as follows: the authorized counterparty utilizes or operates the communication tool number associated with the seal sample authentication or the communication tool number serving as the basis for the authorized counterparty's associated code information, establishes communication contact with the electronic seal function software through the electronic seal authentication communication interface, and makes a request for authentication, extraction or review of the seal sample; the request information includes the seal subject associated information or the seal sample associated code or a combination of the two; after receiving the above request, the electronic seal function software extracts the communication tool number information requested by the authorized counterparty, combines the seal subject associated information or the seal sample associated code or a combination of the two submitted by the authorized counterparty, and searches the database for a seal sample that matches the above-mentioned associated elements; if the match is successful, the request is granted. Otherwise, the request is rejected. The matching of the communication tool number information requested by the authorized counterparty with the authorized counterparty's communication tool number information associated with the seal sample authentication in the database is a necessary condition for granting the request. Establishing communication with the electronic seal function software through the electronic seal authentication communication interface includes, but is not limited to, the following: dialing the electronic seal authentication communication interface phone number, sending a text message to the electronic seal authentication communication interface, sending an email to the electronic seal authentication communication interface, accessing the electronic seal authentication communication interface WeChat public account, logging into the electronic seal authentication communication interface website, etc. The seal subject-related information refers to identity-related information related to the seal subject, including but not limited to the seal subject name, seal subject code, seal subject abbreviation, etc.

[0024] In the above method, when the request information submitted by the authorized counterparty contains only the seal subject association information, the electronic seal function software will display a list of all seal samples in the database under the name of the seal subject that are associated with the authorized counterparty's exclusive communication tool number authentication to the authorized counterparty for selection. When the request information submitted by the authorized counterparty contains only the seal sample association code, the electronic seal function software will search the database for a seal sample that satisfies both the authorized counterparty's exclusive communication tool number authentication association and the seal sample association code association. If the match is successful, the request will be granted. When the request information submitted by the authorized counterparty includes the combination of seal subject association information and seal sample association code, it is a precise authentication request, and the corresponding seal sample must simultaneously match the exclusive communication tool number, seal subject association information, and seal sample association code associated with the authorized counterparty's authentication. The electronic seal function software will search the database for a seal sample that meets the matching requirements. If the match is successful, the request will be granted.

[0025] Furthermore, when the authorized counterparty needs to sub-authorize other people to authenticate, extract or review the seal sample, the method is: the authorized counterparty's sub-authorizer submits a request for authentication, extraction or review of the seal sample to the electronic seal function software, and the request information submitted must include the communication tool number information associated with the authorized counterparty and the seal sample authentication or the communication tool number information as the basis of the authorized counterparty's associated code information, and also include one of the following information or a combination of both: seal body associated information or seal sample associated code; after receiving the above request, the electronic seal function software extracts the communication tool number of the authorized counterparty in the request information The electronic seal function software searches for a matching seal sample in the database based on the seal subject association information or seal sample association code information in the request information, or a combination of the two. If a matching seal sample exists, the electronic seal function software sends a transfer authorization confirmation message to the communication tool number of the authorized counterparty. The authorized counterparty forwards the received confirmation message to the transferor. The transferor uses the received confirmation message to submit a transfer authorization qualification matching request to the electronic seal function software. The electronic seal function software performs a matching judgment. If the match is successful, the transfer authorization is completed, and the transferor obtains the authentication right, extraction right, or inspection right of the associated seal sample. The transfer authorization confirmation message can be a dynamic SMS verification code, a URL link and file extraction code of the seal sample, or a specific method for authenticating, extracting, or viewing the seal sample.

[0026] The preferred solution is that the electronic seal function software is an electronic seal function software platform that is managed by a third-party certification agency.

[0027] A preferred solution is that the seal pattern or its attached information area of ​​the paper-based visual identification anti-counterfeiting electronic seal also includes associated mark information or authentication communication interface information of the electronic seal authentication agency.

[0028] The preferred solution is that the paper-based visual recognition anti-counterfeiting electronic seal is used in combination with identity authentication, electronic signature or time stamp technology for the seal subject, seal operator and relevant parties.

[0029] The seal subjects described in the claims and specification of the present invention include natural persons, legal persons, and other organizations. The authentication described in the present invention means that the recipient of the seal sample or other relevant persons confirms the authenticity of the seal sample. The authentication of the seal sample described in the present invention includes but is not limited to the following forms: the person requesting authentication uploads the seal sample, which is automatically compared and authenticated by the electronic seal function software; the person requesting authentication extracts the seal sample and compares and authenticates it by himself, including: directly downloading from the background of the electronic seal function software and sending the file to the authorized extractor by the electronic seal function software; the person requesting authentication reviews and compares the seal sample online. Since the recipient of the seal sample extracts or reviews the seal sample not solely for the purpose of authentication, the claims and specification of the present invention treat authentication (authentication right), extraction (extraction right), and review (review right) in a parallel manner. The authentication association with the seal sample described in the present invention means that when the recipient of the seal sample needs to authenticate, extract, or review the seal sample, the authentication-associated information and the seal sample are directionally bound. The authorized counterparty described in the present invention refers to a natural person, legal person, or other organization that is granted the right to authenticate, extract, or review the seal sample during the stamping event or with respect to the seal sample formed by the stamping by the seal subject or seal operator. The authorized counterparty described in the present invention is to be distinguished from the electronic seal subject itself or the electronic seal operator. However, the electronic seal operator can also serve as the authorized counterparty. For a contract signed by two or more parties, the authorized counterparty of the seal subject of any party to the contract includes, but is not limited to: the contract counterparty (a natural person, legal person, or other organization. For example, if the electronic seal subject of the contract is Party A, then Party B, Party C, etc. are the contract counterparty; for example, in the case of a labor contract, the contracting unit and the employee are each other's contract counterparties), the contract counterparty's authorized representative, a third party authorized for the contract text, a public authority or other third party authorized by law to authenticate, review, or extract the seal sample, and other persons authorized by the seal subject. For documents affixed to a unilateral seal (such as authorization letters, declarations, official letters, notices, and circulars), the authorized counterparty includes, but is not limited to, the authorized party and the specific recipient of the declaration, official letter, notice, and circular. In the present invention, when the authorized counterparty is a legal person or other organization, the actions of its authorized agent (authorized handler) are deemed to be the same as those of the authorized counterparty.

[0030] The direct visual reading described in the present invention means that the relevant codes can be read without the aid of other equipment or software, such as digital codes, letter codes, text codes, or mixed codes of numbers, letters and texts. Bar codes or QR codes are typical codes that cannot be directly read visually and need to be read with the aid of corresponding electronic equipment before subsequent anti-counterfeiting authentication operations can be performed. When evaluating large quantities of stamped samples, it is very easy to miss the anti-counterfeiting authentication judgment because the corresponding reading and judgment actions are too complicated. Therefore, the relative person has a strong need to visually distinguish the authenticity. Moreover, bar codes or QR codes are not easy to be conveniently identified when they are copied or forged. The communication and communication, communication interface and communication interface of the present invention are equivalent.

[0031] Establishing an authorized counterparty authentication association mechanism allows electronic seal stamp samples to be specifically targeted, thereby preventing unauthorized personnel from intervening in the authentication of stamp samples. By presenting the stamp code information and the ownership counterparty association code information on the seal pattern, each stamped seal pattern can be easily unique (although uniqueness is not a rigid requirement of the present invention). Therefore, illegal copying is easily exposed. Especially when presented in a directly readable format, visual verification of the electronic seal's authenticity is extremely convenient and highly reliable. This significantly increases the difficulty for counterfeiters to conceal flaws. When the authorized counterparty uses or manipulates the communication tool number (especially a mobile phone number) associated with their authentication to conduct actual authentication, the counterfeiter is effectively undetectable. Unauthorized users of the stamp sample, without access to the authorized mobile phone number, are unable to authenticate, retrieve, or review the stamp sample. The purpose of presenting some or all of the authorized counterparty's communication tool number information in the authorized counterparty association code of the seal pattern is to prevent illegal copying of the seal pattern. If the seal pattern is copied as is, the copier will not have the corresponding authorized communication tool number information, making it easy to be exposed. Conversely, if the copier's own communication tool number information is added to the seal pattern, the identity authentication of the electronic seal function software platform will not be passed. Therefore, the electronic seal of the technical solution of the present invention has a strong anti-counterfeiting function when the seal pattern is printed on paper.

[0032] The core solution of the present invention is to use the mobile phone number as the basis for the association code of the authorized counterparty, because the mobile phone number has the following characteristics: 1. Relatively authoritative third-party real-name authentication makes it have a relatively clear identity orientation; 2. Dynamic interactive function of information; 3. Instant face-to-face authentication. Instant face-to-face authentication includes at least two levels of content: one is whether the relevant personnel control or use the mobile phone number in real time - this can be confirmed by dialing in person; the other is whether the mobile phone number has obtained the authentication qualification of the authentication object - this can be confirmed or falsified by operating the mobile phone number in person to carry out instant authentication. The instant dynamic identity confirmation feature and information interaction feature of the mobile phone number are not possessed by other identity feature information. Other communication tool numbers also have the above characteristics to a certain extent, but the reliability and convenience are far inferior to mobile phone numbers.

[0033] There are three levels of authentication for electronic seals. The first level is online authentication, which verifies the authenticity of a seal sample by verifying its electronic signature, timestamp, hash value, and other elements. This level of authentication is highly reliable but inconvenient—comparable to a DNA test, a common technique used in existing technologies. The second level is offline electronic code scanning authentication, which requires an electronic device with code scanning capabilities and communication with a network backend to confirm the authenticity of the seal sample—equivalent to verifying an ID card. This level is relatively reliable but still inconvenient. The third level is where the authentication elements on the electronic seal image are directly readable by the naked eye. This level provides a preliminary level of authenticity verification without the need for any equipment, making it extremely convenient compared to everyday appearance recognition. Visual recognition is further combined with the authentication elements presented in the electronic seal image for electronic authentication via a network backend, resulting in extremely reliable and convenient authentication. Therefore, the third level of electronic seal authentication offers both convenience and reliability, making it the most practical. The third-level electronic seal anti-counterfeiting can be combined with the first-level online anti-counterfeiting method to achieve full online and offline electronic seal anti-counterfeiting coverage.

[0034] The paper-based visual recognition anti-counterfeiting electronic seal of the technical solution of the present invention, whether its seal pattern is printed on paper or published in cyberspace in the form of a picture, still has a very strong anti-counterfeiting function, that is, it has a visual anti-counterfeiting function. The electronic seal of the present invention is combined with the electronic signature and time stamp technology that has been maturely applied by various online signing platforms, which can completely solve the problem of seal anti-counterfeiting in all application scenarios of online and offline, electronic level and paper level. The paper-based visual recognition anti-counterfeiting electronic seal of the present invention is a powerful extension of the current service model of the online signing platform. The implementation method of the paper-based visual recognition anti-counterfeiting electronic seal of the present invention is easy to operate, reliable to use, and has strong anti-counterfeiting properties.

[0044] The implementation method of the paper-based visual recognition anti-counterfeiting electronic seal of the present invention is realized by the electronic seal function software. The electronic seal function software is configured with an electronic seal authentication communication interface. When the user needs to stamp, the electronic seal function software is operated to generate a seal pattern and affix it to the electronic text to be stamped. The seal pattern of the paper-based visual recognition anti-counterfeiting electronic seal includes a fixed information unit and a dynamic information unit. As shown in Figure 1, the seal pattern of the paper-based visual recognition anti-counterfeiting electronic seal includes a fixed information unit and a dynamic information unit. The fixed information unit includes: the name of the seal subject 1, the seal logo five-pointed star, the seal subject code 2 or the seal type name contract special seal. The dynamic information unit is a set of authorized counterparty association codes 4 - in this embodiment, it is displayed as "counterparty 13912345678", which is the mobile phone number of the authorized counterparty. The authorized counterparty association code 4 is generated by the following method: the electronic seal operator submits the authorized counterparty's unique mobile phone number information to the electronic seal function software; the electronic seal function software selects the above mobile phone number as the authorized counterparty association code 4, and solidifies the authorized counterparty association code 4 in a directly visually readable form in the generated seal pattern.

[0045] The authorized counterparty association code 4, presented in a non-visible form such as a QR code or barcode within the electronic seal pattern, also has a certain offline authentication function. However, because it lacks visual recognition and anti-counterfeiting capabilities, QR codes are inconvenient and cumbersome to use when managing and screening large amounts of contract documents. More importantly, they are easily forged without being noticed. These shortcomings have prevented widespread user acceptance in terms of application and operation.

[0046] Using the authorized counterparty's exclusive communication tool number as a tool for authenticating the stamp sample has the advantages of convenient operation and high reliability. Among them, the mobile phone number is the most convenient and reliable. The specific authentication process for the stamp sample is as follows: the authorized counterparty uses or operates the mobile phone number associated with the stamp sample authentication to send an authentication request SMS to the electronic seal authentication communication interface of the electronic seal function software in accordance with the regulations. The request information includes the seal subject name 1. The electronic seal function software extracts the mobile phone number information that sent the request message and compares it with the authorized counterparty's authenticated mobile phone number information in the database. If a match is successful, the identity authentication is completed; the electronic seal function software allows the above-mentioned authorized counterparty to authenticate, extract or review the stamp sample for this time or this batch. The electronic seal function software replies to the mobile phone number of the authorized counterparty who made the request with the authentication, extraction, and review method or authentication, extraction, and review website of the stamp sample via SMS. In this embodiment, the background database will display all the stamp samples matching the seal subject name 1 under the name of the authentication-associated mobile phone number to the authorized counterparty for selection. If the above identity information fails to match, the electronic seal function software will reject the request.

[0047] In this embodiment, using the authorized counterpart's exclusive email address as the authentication association tool is also a reliable and convenient preferred solution, but it is not as convenient as a mobile phone number.

[0048] Taking the email address as the communication tool number information of the authorized counterparty associated with the authentication as an example, the following is explained: the authorized counterparty uses or operates the email address associated with the seal sample authentication to send an authentication request email to the electronic seal authentication communication interface of the electronic seal function software in accordance with the regulations. The request information includes the seal subject name 1. The electronic seal function software extracts the email address information that sends the request information, and compares it with the email address information of the authorized counterparty in the database. If they match, the identity authentication is completed; the electronic seal function software allows the above-mentioned authorized counterparty to authenticate, extract or review the seal samples for this time or this batch. The electronic seal function software replies to the email address of the authorized counterparty who made the request with the authentication, extraction, and review method or authentication, extraction, and review website of the seal sample by email. If the above-mentioned email address number information fails to match, the electronic seal function software rejects its request.

[0049] Using WeChat, QQ, MSN and other instant messaging software numbers instead of mobile phone numbers can basically achieve similar functions. However, since additional operations such as following or adding as friends are required first, and interactive communication is not necessarily carried out in real time, instant messaging software numbers are not as convenient and reliable as mobile phone numbers. Example 2

[0050] The present invention provides a method for implementing a visual anti-counterfeiting electronic seal, which is implemented through electronic seal function software. The electronic seal function software is equipped with technical means such as identity authentication, electronic signature, time stamp, and an electronic seal authentication communication interface. As shown in Figure 2, the seal pattern of the electronic seal includes a fixed information unit and a dynamic information unit. The fixed information unit includes the seal subject name 1, the seal logo five-pointed star, and the seal type contract patent seal. The dynamic information unit includes an authorized counterparty association code 4 and a seal sample association code 3. The authorized counterparty association code 4 and the seal sample association code 3 are presented in the form of digital codes that can be directly read visually. Compared with Example 1, the authorized counterparty association code 4 does not display the complete mobile phone number, but only intercepts the first and last digits of the mobile phone number, and the middle digits are replaced by * or other symbols. This processing is conducive to protecting commercial secrets and also protects the privacy of the counterparty to a certain extent, but basically does not affect the uniqueness and anti-counterfeiting characteristics of the electronic seal pattern.

[0051] The same method can also be applied to a natural person's private seal or a legal representative's special seal, as shown in Figure 3. The seal pattern includes the natural person's name, the authorized counterparty association code 4, and the seal sample association code 3. If necessary, the time information of the seal operation can also be added to the dynamic information unit.

[0052] The authorized counterparty association code 4 is generated by the following method: the stamp operator enters the mobile phone number information of the authorized person to extract the stamp sample into the background database, and associates the mobile phone number information with the stamp sample for authentication, as a means of authentication for the stamp sample authentication qualification, extraction qualification or review qualification. If there are multiple groups of associated mobile phone number information, the authorized counterparty association code 4 can select one group, or multiple groups can be selected to be presented in the seal pattern in a directly visually readable manner. In this embodiment, one group of mobile phone numbers is selected, and the first and last digits of the mobile phone numbers are intercepted to form the authorized counterparty association code 4. At this time, the authorized counterparty association code 4 is equivalent to a set of secret codes. Only the person who controls the mobile phone number or other informed persons know the complete mobile phone number behind it. The complete mobile phone number can be used to obtain the authentication information, extraction qualification or review qualification of the stamp sample. For mobile phone number information that does not need to be presented in the seal pattern as the authorized counterparty association code 4, it can also be added after stamping. In this embodiment, an email address number is used instead of a mobile phone number, which has a basically similar effect.

[0053] The stamp sample association code 3 is generated by the following method: when the electronic seal is stamped, the electronic seal function software automatically generates the stamp sample association code 3 for this or this batch of stamping operations of the electronic seal, and associates the stamp sample association code 3 with the stamp sample. The stamp sample association code 3 can be a set of random numbers, or it can use the associated numbers of the cumulative number of stamps of the electronic seal, or it can extract the time information of the stamping operation. This time information can be used as the basic information of the stamp sample association code 3, or it can be displayed independently in the electronic seal pattern. By using the associated numbers of the cumulative number of stamps of the electronic seal or the stamping time information with a certain degree of accuracy (for example, accurate to minutes or even seconds), the single element of the stamp sample association code 3 also has a strong unique feature.

[0054] The specific authentication process for the stamp sample is as follows: the authorized counterparty uses or operates the mobile phone number associated with the stamp sample authentication to send an authentication request SMS to the electronic seal authentication communication interface of the electronic seal function software according to the specified requirements. The request information includes the seal subject name 1 and the stamp sample association code 3. The electronic seal function software extracts the mobile phone number information that sends the request message and compares it with the mobile phone number information associated with the authorized counterparty through authentication in the database. If the match is successful, the identity authentication is completed; the electronic seal function software grants the above-mentioned authorized counterparty the authentication right, extraction right or inspection right for this batch of stamp samples. The electronic seal function software replies to the mobile phone number of the above-mentioned authorized counterparty with the authentication, extraction, and inspection method or authentication, extraction, and inspection website of the stamp sample in the form of an SMS. Compared with Example 1, this embodiment is a precise authentication. The background database will display the stamp sample under the name of the authentication-associated mobile phone number and that matches the seal subject name 1 and the stamp sample association code 3 to the authorized counterparty for authentication, extraction or inspection. If only the seal subject name 1 matches successfully, but the seal sample association code 3 does not match successfully, the electronic seal function software platform will display all seal samples associated with the seal subject name 1 under the authorized counterparty's mobile phone number for the authorized counterparty to select. If the above identity information matches unsuccessfully, the electronic seal function software will reject the request. Example 3

[0055] The implementation method of the paper-based visual identification anti-counterfeiting electronic seal of the present invention is implemented and managed by a third-party certification agency. The third-party certification agency is provided with an electronic seal function software platform, which provides electronic seal generation, storage and anti-counterfeiting certification services to users, and is equipped with technical means such as identity authentication, electronic signature and time stamp. The third-party electronic seal certification agency and the seal subject unit establish an electronic seal service relationship recognized by both parties, and establish a database of the seal subject unit's identity information and electronic seal authentication information. The seal subject unit is bound to a mobile communication number for sending or receiving electronic seal authentication information. The bound mobile communication number is pre-registered in the database of the seal subject unit's identity information and electronic seal authentication information established by the third-party electronic seal certification agency. For the seal subject user, a USB-Key form of identity authentication mode can also be adopted.

[0056] As shown in Figure 4, the seal pattern of the electronic seal includes a fixed information unit and a dynamic information unit. The fixed information unit includes the seal body name 1, the seal logo five-pointed star and the seal body code 2. The dynamic information unit includes a seal sample association code 3 and an authorized counterparty association code 4. The generation method of the authorized counterparty association code 4 and the seal sample association code 3 refers to Example 1 or Example 2 respectively. The seal sample association code 3 and the authorized counterparty association code 4 are presented in the form of digital codes that can be directly read visually. The authorized counterparty association code 4 of this embodiment is the mobile phone number of the authorized counterparty. At the same time, the seal pattern also includes authentication communication interface information 5. The electronic seal authentication communication interface information 5 can be a customer service phone number, an email address, an authentication website, an instant messaging tool account or a self-media account, etc. The authorized counterparty or other authorized authentication personnel can establish communication contact with the electronic seal function software platform through the electronic seal authentication communication interface 5 and submit a request for authentication, extraction or review that matches the seal. The authentication agency identity feature mark may also be used to replace the authentication communication interface information 5. In this case, the authentication agency identity feature mark is associated with the default authentication communication interface information 5.

[0057] The process of generating and using the electronic seal in this embodiment is shown in FIG7 , and is specifically as follows:

[0058] In step 101, the user (electronic seal operator) logs into the electronic seal software platform, prepares the electronic document to be stamped, and after passing the platform's identity authentication, is authorized to use the electronic seal. In practice, the steps of preparing the electronic document to be stamped and verifying the platform's identity can be performed at any time before the stamping operation.

[0059] In step 102, the user (electronic seal operator) submits the interactive communication tool number information of the authorized counterpart to the electronic seal function software platform, and uses it as the authentication association information of this batch of seal samples.

[0060] In step 103, the electronic seal software platform selects part or all of the submitted interactive communication tool number information to form part or all of the authorized counterparty association code 4, and then solidifies the generated authorized counterparty association code 4 in a visually readable form within the electronic seal pattern. In this embodiment, this step can be specifically detailed as follows: the electronic seal software platform uses the entire submitted mobile phone number as the authorized counterparty association code 4.

[0061] In step 104 , the user (electronic seal operator) performs a stamping operation, and the electronic seal function software platform generates a stamp sample associated code 3 , and solidifies the stamp sample associated code in the electronic seal pattern in a form that can be directly read visually.

[0062] In step 105 , the user (electronic seal operator) stamps the generated seal pattern on the electronic text to be stamped.

[0063] Step 106: The electronic seal function software platform (backend server, database or operating computer) retains the seal sample formed after the seal operation.

[0064] Inserting the above steps as a whole or splitting them into more electronic seal usage steps is also within the scope of protection of the present invention, such as performing identity authentication first or inserting the identity authentication process in the middle of the operation, inserting the electronic signature operation and retaining the relevant data, recording and saving the timestamp data during the stamping operation, etc.

[0065] The authorized counterparty of the seal sample can obtain certification, extraction, or review qualifications for the seal sample by using the mobile phone number used as the authorized counterparty association code 4. If the mobile phone number information of authorized counterparties that does not have the authorized counterparty association code 4 is registered in the database and the electronic seal operator has authenticated and associated it with the seal sample, this mobile phone number information can also be used by the authorized counterparty to obtain certification, extraction, or review qualifications for the associated seal sample.

[0066] When the authorized counterparty needs to authenticate, extract or review the seal sample, he / she can use the mobile phone number displayed in the authorized counterparty's associated code 4 to send an authentication SMS to the authentication service communication interface of the certification agency to obtain authorization to authenticate, extract or review the associated seal sample. The specific method of authenticating, extracting or reviewing the seal sample is shown in Figure 8, including the following steps:

[0067] In step 201, the authorized counterparty uses their authenticated mobile phone number to establish communication with the authentication communication interface of the electronic seal software platform and submits a request for authentication, retrieval, or review of a seal sample. The request includes the seal subject's identity information, the seal sample's associated code, or a combination of the two. The seal subject's identity information is set according to regulations and can include, for example, the seal subject's name, abbreviation, or identity code.

[0068] In step 202, the electronic seal function software platform searches for a matching seal sample in the database according to the mobile phone number requested by the authorized counterparty and the information submitted.

[0069] Step 203, Match Determination, proceeds to step 2041 or step 2042, depending on whether the match is successful or not. In this step, the requesting mobile phone number and the corresponding authorization qualifications are prerequisites and necessary conditions for a successful match. The authorized counterparty can first be authenticated, that is, the requesting mobile phone number is matched with the authenticated authorized counterparty mobile phone number information in the database (or a dynamic SMS verification code verification can be used), and then a seal sample is searched for that matches the seal subject name or seal sample associated code. Alternatively, a matching search can be performed simultaneously on the authorized counterparty's requesting mobile phone number and the seal subject name or seal sample associated code.

[0070] In step 2041, if the match is successful, the electronic seal software platform allows the authorized counterparty to authenticate, retrieve, or view the associated seal samples. This step can be further refined as follows: the electronic seal software platform sends a seal sample retrieval link and retrieval code to the mobile phone number. The authorized counterparty logs in to the link and enters the retrieval code to retrieve all associated seal samples.

[0071] Step 2042: If the match fails, the request is rejected.

[0072] For non-authorized persons of this stamp sample, there is no way to authenticate, extract or check the stamp sample because they do not have the authorized mobile phone number. The reason why the authorized mobile phone number information of some or all authorized counterparties of the stamp sample is presented in the authorized counterparty association code 4 of the seal pattern is to block the illegal copying of the seal pattern. If the seal pattern is copied as it is, the copier does not have the corresponding authorized mobile phone number information and is easily exposed. On the contrary, if one's own mobile phone number information is forced into the seal pattern, the identity authentication of the electronic seal function software platform cannot be passed. Therefore, the electronic seal of the technical solution of the present invention still has a very strong anti-counterfeiting function after its seal pattern is printed on paper. The electronic seal of the present invention is combined with the currently mature online signing platform model, which can completely solve the seal anti-counterfeiting problem in all application scenarios of online and offline, electronic level and paper level.

[0073] This embodiment uses a mobile phone number as the authorized counterparty association code 4 and displays the full mobile phone number information. Using an email address instead of a mobile phone number also achieves essentially the same functionality. Of course, the mobile phone number in this embodiment can also be replaced with a QQ number, WeChat number, or other instant messaging tool number. However, in comparison, the mobile phone number provides much stronger identity authentication, operational convenience, and manageability.

[0074] In this embodiment, the authorized person who retrieves the seal sample and the authorized person who inspects it have different permissions. The authorized person who inspects the seal sample only has the right to inspect the seal sample, not the right to retrieve it. Furthermore, the electronic seal pattern of the seal sample they inspect contains a watermark or has been distorted. This allows the authorized person to verify the authenticity of the electronic seal, but not to copy the electronic seal pattern exactly.

[0075] When a new authorized counterparty or external person needs to authenticate, extract, or review a seal sample, they will need to obtain authorization from the seal operator and add the new authorized counterparty's or external person's mobile phone number, email address, or other communication tool number information to the authorized counterparty authentication associated information list in the database. At this time, the mobile phone number or email address of this new authorized counterparty cannot be displayed and does not need to be displayed in the dynamic information unit of the seal pattern, but its authentication function can still be the same as the communication tool number information associated with the previous authorized counterparty authentication.

[0076] In another case, external relevant personnel can obtain the qualification to authenticate, extract, or review the seal sample through the authorization counterparty's sub-authorization. The authorized counterparty's sub-authorizer submits a request for authentication, extraction, or review of the seal sample to the electronic seal function software platform. The request information submitted must include the mobile phone number or email number information authenticated by the authorized counterparty, as well as: seal subject association information or seal sample association code 3; the electronic seal function software platform sends a dynamic verification code to the mobile phone number or email number authenticated by the authorized counterparty submitted by the sub-authorizer; the authorized counterparty forwards the received dynamic verification code to the sub-authorizer; the sub-authorizer submits the received dynamic verification code to the electronic seal function software platform. If a match is successful, the sub-authorization license is completed, and the sub-authorizer obtains the authentication, extraction, or review rights of the associated seal sample. The electronic seal function software platform then sends the authentication, extraction, or review method of the seal sample to the sub-authorizer.

[0077] The sub-authorization method may also be: after receiving the above-mentioned sub-authorization request, the electronic seal function software platform sends a URL link and a file extraction code to the mobile phone number or email number associated with the authorized counterparty submitted by the sub-authorizer; the authorized counterparty forwards the received URL link and file extraction code to the sub-authorizer; the sub-authorizer uses the mobile phone number obtained through sub-authorization as the identity basis to log in to the URL for authentication, extract or check the seal sample. Example 4

[0078] The electronic seal function software is an electronic seal function software platform provided by a third-party certification agency, which provides users with electronic seal generation, storage and anti-counterfeiting certification services, and is equipped with technical means such as identity authentication, electronic signature, and time stamp. The third-party electronic seal certification agency and the seal subject unit establish an electronic seal service relationship recognized by both parties, and establish a database of the seal subject unit's identity information and electronic seal authentication information. The seal subject unit is bound to a mobile communication number to send or receive electronic seal authentication information. The bound mobile communication number is pre-registered in the seal subject unit's identity information and electronic seal authentication information database established by the third-party electronic seal certification agency. For seal subject users, a USB-Key form of identity authentication mode can also be used.

[0079] When a user needs to use an electronic seal, he / she logs in to the electronic seal function software platform, obtains authorization to use the seal through identity authentication or electronic signature, opens, imports, inputs or uploads the electronic text to be stamped through the electronic seal function software platform, and generates a seal pattern by operating the electronic seal function software platform and stamps it on the electronic text.

[0080] As shown in Figure 5, the seal pattern of the paper-based visual identification anti-counterfeiting electronic seal includes a fixed information unit and a dynamic information unit. The fixed information unit includes the seal subject name 1, the seal subject code 2, the seal logo five-pointed star, and the authentication communication interface information 5 or identity feature mark or code of the third-party authentication agency. The dynamic information unit includes the authorized counterparty association code 4 and the seal sample association code 3. The authorized counterparty association code 4 and the seal sample association code 3 are presented in the form of digital codes that can be directly read visually. The generation method of the authorized counterparty association code 4 and the seal sample association code 3 refers to Example 1 or Example 2.

[0081] The seal pattern generated by the anti-counterfeiting electronic seal includes, in addition to the main pattern, an auxiliary information area. The information in the main pattern and the information in the auxiliary information area together constitute the complete anti-counterfeiting authentication information of the seal. The main seal pattern is a circular official seal, including the seal body name 1, the seal logo five-pointed star and the seal body code 2, which belong to the fixed information unit. At the same time, the main seal pattern also includes a seal sample association code 3, which belongs to the dynamic information unit. The seal sample association code 3 is a code formed based on the cumulative number of stamps of the electronic seal. The auxiliary information area is an annular area formed outside the main circular seal pattern. The auxiliary information area includes 4 groups of mobile phone numbers of the authorized counterparties of the seal samples. In addition, the auxiliary information area also includes a group of certification agency identity codes 5, which are composed of the abbreviation and service telephone number of the third-party certification agency.

[0082] The process of generating and using the paper-based visual recognition electronic seal and the method of authenticating, extracting or checking the seal sample in this embodiment refer to Example 1, Example 2 or Example 3. Example 5

[0083] As shown in Figure 6, referring to Example 4, the seal pattern generated by the paper-based visual recognition anti-counterfeiting electronic seal includes, in addition to the main pattern, an ancillary information area. The information within the main pattern and the ancillary information area together constitute the complete anti-counterfeiting authentication information for the seal. The main seal pattern is a circular official seal, which includes the seal body name 1, the seal logo five-pointed star, and the seal body code 2, which are fixed information units. The main seal pattern also includes a seal sample association code 3, which is a dynamic information unit. The seal sample association code 3 is based on the cumulative number of times the electronic seal has been stamped. The ancillary information area is a rectangular frame that includes four sets of mobile phone numbers of the authorized counterparties of the seal samples and a set of time information when the seal was stamped. This time information essentially constitutes another set of seal sample association codes. The middle four digits of each of the four mobile phone numbers are hidden to protect the privacy of the authorized counterparties without affecting their functionality. The rectangular frame ancillary information area of ​​this embodiment, without the border, is a typical amorphous ancillary information area.
