Description

Technical Field

[0001] This invention relates to the fields of commodity information management and trademark design, specifically a method for combining commodity spatiotemporal information with trademarks to achieve identification functions. Background Technology

[0002] In modern society, consumers have higher demands for product transparency and traceability. Whether in daily shopping or in ensuring food and pharmaceutical safety, the ability to understand the origin, production date, and distribution status of goods in real time and accurately is particularly important. However, existing trademarks can only provide basic brand identification functions and cannot effectively carry detailed spatiotemporal information about goods.

[0003] In existing technologies, trademarks, as identifiers of goods, are primarily used for brand recognition. Through information carriers such as barcodes and QR codes, trademarks can provide basic information about goods to a certain extent, such as product identification and production batch numbers. These information carriers are widely used in product traceability and anti-counterfeiting, helping consumers verify the authenticity of goods. QR codes and barcodes can be scanned to obtain the production date, batch information, and related product descriptions, improving the transparency and convenience of product information, especially in the retail and logistics sectors, where they have played a relatively effective role.

[0004] However, existing technologies have some shortcomings and cannot effectively meet the needs for carrying and updating product spatiotemporal information in real time. First, the product information carried by existing trademarks is limited to simple identifiers and traceability codes, failing to effectively integrate multi-dimensional information such as production time and logistics routes into the trademark, resulting in consumers not being able to fully understand the circulation process and status of the product. Furthermore, the information in existing technologies is usually static; the spatiotemporal information generated during the product circulation process is not reflected in the trademark in a timely manner, leading to information lag or incompleteness. More importantly, existing trademark designs often do not consider the effectiveness of information carrying; excessively adding information carriers such as QR codes and barcodes can easily affect the trademark's recognizability and aesthetics. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a method for combining product spatiotemporal information with trademarks to achieve identification functions, solving the problem that trademarks in existing technologies can only carry basic brand information and cannot effectively embed the multidimensional spatiotemporal information of products.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a method for combining the spatiotemporal information of goods with trademarks to achieve identification functions, comprising the following steps:

[0007] S1. Collect the spatiotemporal information of the goods, including production time, production batch and logistics route information, and the spatiotemporal information is represented as a data set;

[0008] S2. Encrypt the spatiotemporal information by using an encryption algorithm to generate encrypted spatiotemporal information to ensure the security of the spatiotemporal information;

[0009] S3. The encrypted spatiotemporal information is mapped using manifold theory, and the encrypted spatiotemporal information is mapped onto the two-dimensional plane of the trademark using a manifold embedding algorithm, thereby realizing the effective carrying of information in the trademark space.

[0010] S4. Embed the mapped spatiotemporal information into the trademark to ensure that the trademark can carry sufficient spatiotemporal information of the goods without affecting its recognizability and aesthetics;

[0011] S5. Update the spatiotemporal information in the trademark in real time, and ensure the accuracy and completeness of the embedded spatiotemporal information throughout the circulation process according to the commodity circulation status.

[0012] Preferably, in step S1, the spatiotemporal information of the product includes:

[0023] Manifold mapping method: Using manifold theory, encrypted spatiotemporal information is mapped from a high-dimensional space to a low-dimensional trademark design plane; the mapping process is carried out by optimizing the objective function;

[0024] The objective function can be expressed as:

[0025]

[0026] In the formula, Information Redundancy represents the spatiotemporal information redundancy, and the optimization objective is to minimize redundancy; I entropy S is the entropy of spatiotemporal information, used to measure the richness of information; design To achieve simplicity in trademark design, the optimization objective is to minimize complexity; J represents the optimization objective function; α represents the weight coefficient related to the redundancy of spatiotemporal information in the optimization objective function; β represents the weight coefficient related to the richness of spatiotemporal information and the simplicity of trademark design in the optimization objective function.

[0027] The optimization objective function ensures that the mapping of spatiotemporal information does not lose its geometric characteristics during the mapping process, while maximizing the information carrying capacity.

[0028] Preferably, in step S3, mapping the encrypted spatiotemporal information onto the two-dimensional plane of the trademark using a manifold embedding algorithm includes:

[0029] Optimization of the mapping process: When mapping high-dimensional spatiotemporal information to the two-dimensional plane of the trademark using the manifold embedding algorithm, the distance between the spatiotemporal information is calculated to optimize the mapping.

[0030] The Euclidean distance between spatiotemporal data points is used to determine the position of the mapped information points on the trademark plane, as shown in the following formula:

[0031] D(T i ,T j )=||T i -T j ||2;

[0032] In the formula, T i and T j For the i-th and j-th data items in the spatiotemporal information; D(T) i ,T j ) represents spatiotemporal information T i and T j The Euclidean distance between them;

[0033] Spatial distribution optimization: Based on these distances, the mapped spatiotemporal information is evenly distributed in the trademark plane through an optimization algorithm.

[0034] Preferably, in step S4, embedding the mapped spatiotemporal information into the trademark includes:

[0035] Information carrying area selection: Select a certain area of ​​the trademark as the carrying area for spatiotemporal information. The selection of the carrying area takes into account the shape, size and visual effect of the trademark to ensure that the carrying of trademark information does not affect its recognizability.

[0036] Encoding method: Encrypted spatiotemporal information is embedded in the trademark graphic using QR codes and barcodes to ensure that the information can be read by scanning; the size and position of the QR codes and barcodes should be optimized according to the trademark design.

[0037] Preferably, the selection of a portion of the trademark as the region carrying spatiotemporal information includes:

[0038] Regional selection criteria: Based on the overall design of the trademark, a portion of the area is selected as the area to carry spatiotemporal information;

[0039] The selection of the area takes into account the overall visual effect and information carrying capacity of the trademark, ensuring that the selected area can accommodate the encrypted spatiotemporal information.

[0040] Trademark graphic optimization: In the graphic design of a trademark, the optimal information-carrying area is determined through optimization algorithms.

[0041] Preferably, in step S4, the real-time updating of the spatiotemporal information in the trademark includes:

[0042] Commodity circulation status monitoring: Through Internet of Things (IoT) technology, the circulation status of commodities is tracked in real time, including the transportation route, inventory status, and sales channels of the commodities;

[0043] Real-time information update mechanism: Through a pre-set automated update system, the spatiotemporal information in the trademark will be adjusted and updated in real time according to changes in the circulation status of the goods.

[0044] Preferably, the real-time tracking of the circulation status of goods through Internet of Things (IoT) technology includes:

[0045] Real-time product tracking: Monitor the transportation process, inventory status, and sales channels of goods through IoT devices to obtain real-time information on product circulation;

[0046] The circulation status information includes the location, status, and processing of goods during transportation;

[0047] Data synchronization mechanism: The circulation status is updated synchronously with the trademark embedding system through IoT devices.

[0048] This invention provides a method for combining the spatiotemporal information of goods with trademarks to achieve identification functionality. It has the following beneficial effects:

[0049] 1. This invention adopts a technical solution that combines spatiotemporal information encryption with manifold theory mapping, achieving security protection and effective carrying of commodity spatiotemporal information. Compared with the existing technology that relies solely on simple identifiers or barcodes for information carrying, encryption and manifold mapping effectively avoid the risk of information leakage, while ensuring that the trademark space can carry more commodity information.

[0050] 2. This invention employs Internet of Things (IoT) technology to monitor the real-time circulation status of goods and dynamically update the spatiotemporal information in trademarks based on circulation data. Compared to the static information recording methods in existing technologies, this invention can reflect the transportation, storage, and sales progress of goods in real time, solving the technical problems of delayed and untimely updates of goods information, and improving the timeliness and accuracy of trademark information.

[0051] 3. This invention, through precise design of the information-carrying area in the trademark, ensures that the trademark's recognizability and aesthetics are not affected when carrying spatiotemporal information. Compared with existing technologies that may lead to complex trademark designs or affect brand recognition, this invention, by reasonably optimizing the carrying area, not only guarantees the simplicity and recognizability of the trademark, but also effectively integrates key spatiotemporal information of the product into the trademark, thereby enhancing its functionality.

[0052] 4. This invention combines encryption algorithms, manifold embedding, and real-time update technology to create a highly efficient, secure, and dynamically updated product information system. Compared with the static and singular product information display methods in existing technologies, the dynamic information carrying and real-time update mechanism of this invention solves the problems of opaque and untraceable product information.

[0054] Figure 2 This is a schematic diagram of the spatiotemporal information flow of goods according to the present invention. Detailed Implementation

[0055] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0056] Please see the appendix Figure 1 - Appendix Figure 2 This invention provides a method for combining product spatiotemporal information with trademarks to achieve identification functionality, comprising the following steps:

[0057] S1. Collect the spatiotemporal information of the goods, including production time, production batch and logistics route information, and the spatiotemporal information is represented as a data set;

[0058] Spatiotemporal information of a product is a crucial component of product identification, and its effective collection is the first step in the entire technical solution. By collecting information on the product's production time, batch number, and logistics route, the necessary data foundation can be provided for subsequent steps such as encryption, manifold mapping, trademark embedding, and real-time updates. This spatiotemporal information not only helps identify the product but also provides continuous traceability throughout its entire lifecycle. Reasonable collection of spatiotemporal information ensures the accuracy and effectiveness of data in subsequent technical steps.

[0059] Generally, the spatiotemporal information of a product includes production time, production batch, and logistics route information. Collecting this information provides comprehensive and accurate product identification for trademark design. Specifically, the collected spatiotemporal information is stored as a dataset, providing the necessary raw data for subsequent encryption processing and trademark embedding. This is implemented in the following ways.

[0060] In one possible implementation, the spatiotemporal information includes the following:

[0061] Production Time: Production time information is a crucial identifier for a product, typically including the production date and production cycle. It not only reflects the production process but also provides fundamental data for quality control, shelf life, and distribution. In some embodiments, production time data can be represented as a specific timestamp to precisely identify the product's production time. In one possible implementation, production time information can be automatically acquired by a production management system and recorded in the product's spatiotemporal information dataset.

[0062] Production batch: A production batch refers to the batch number, factory information, and production line number of a product within the same production cycle. Production batch data is one of the important bases for product identification, helping to trace the specific details of a product during the production process. When there is a problem with a product batch, the batch number can be used to trace back to the specific production stage and time, thus providing enterprises with an important quality management tool. The collection of batch information is usually completed by the enterprise's production management system or barcode system, which can effectively identify the batch of each product. Specifically, production batch information can be represented in a format such as "batch number-production line number-production date".

[0063] Logistics route: Logistics route information refers to the transportation path of goods from the production site to the sales site. This information includes the mode of transport, transportation date, and transportation stages. By tracking the logistics route, the transportation process of goods can be understood, thus providing more accurate information on the circulation status of goods. In some embodiments, logistics route data can be automatically recorded by a logistics management system, including the origin, destination, mode of transport (such as land, sea, air, etc.), transit points, and transportation date. Logistics route information may be represented in a format similar to "origin-destination-mode of transport-transport date".

[0064] In some embodiments, spatiotemporal information is represented by a data set T = {T1, T2, T3}:

[0065] In the formula, T1 represents production time information; T2 represents production batch information; and T3 represents logistics route information.

[0066] Specifically, each piece of spatiotemporal information in the data set T has a corresponding timestamp and encoding, ensuring that the data can be accurately stored and transmitted in subsequent processes.

[0067] All spatiotemporal information is automatically collected through the company's internal systems or external sensors and stored in a database for subsequent encryption, mapping, and updating. Alternatively, all spatiotemporal information can be directly associated with the product's barcode or QR code, allowing detailed product information to be obtained by scanning.

[0068] S2. Encrypt the spatiotemporal information by using an encryption algorithm to generate encrypted spatiotemporal information to ensure the security of the spatiotemporal information;

[0069] Encryption of spatiotemporal information is a crucial step in the entire methodology. This step follows the collection of product spatiotemporal information, ensuring that critical information such as production time, batch number, and logistics route is effectively protected when embedded in the trademark. Encryption prevents unauthorized access or tampering of product information during distribution, thereby enhancing product security and anti-counterfeiting capabilities. This step is a vital safeguard for ensuring product information security and protecting trademark innovation.

[0070] In one possible implementation, after the spatiotemporal information is collected and stored, it is encrypted using an encryption algorithm to generate encrypted ciphertext information. This encrypted spatiotemporal information will become part of the trademark and will be subsequently embedded in the trademark design. Therefore, encryption not only ensures the security of the spatiotemporal information but also provides technical support for the subsequent trademark design and information carrying.

[0071] In this embodiment, the spatiotemporal information is first encrypted using a symmetric encryption algorithm. By selecting a highly secure encryption algorithm, the confidentiality of the data can be ensured. In some embodiments, the AES algorithm is used to encrypt the spatiotemporal information. This algorithm is widely used in the field of data encryption, has high encryption strength, and high execution efficiency, making it suitable for the needs of this invention.

[0072] Specifically, the spatiotemporal information T = {T1, T2, ..., T} n Each data item T is encrypted item by item. i This indicates the production time, production batch, or logistics route information of the goods. Each spatiotemporal data item is encrypted using the AES algorithm and converted into ciphertext form E(T). i The specific formula for the encryption process is as follows:

[0073] E(T i ) = AES(T i Key);

[0074] In the formula, T i Represents the data item; Key is the encryption key used, which is generated and stored by a dedicated key management system during encryption. The encrypted spatiotemporal information E(T) i This will become an encrypted carrier of product information, and the encrypted data will be used in subsequent steps for trademark embedding and updating circulation information.

[0075] In one embodiment, the encryption algorithm used, AES (Advanced Encryption Standard), is a symmetric encryption algorithm that uses the same key for both encryption and decryption. This algorithm is widely used in data encryption, offering high security and fast processing speed, and effectively ensuring the security of the spatiotemporal information of goods during storage and circulation.

[0076] Key management is a crucial part of this step. The security of the key directly determines the strength of the encryption process and the confidentiality of the data. To ensure key security, the key management system should employ high-security technologies, such as Hardware Encryption Modules (HSMs) and secure storage, to guarantee key security throughout the entire process. In this way, the key will not be leaked during encryption and decryption, further improving the reliability of information protection.

[0077] Data Encryption Storage: After encryption, the spatiotemporal information is transformed into ciphertext and stored in a data storage system. This system typically uses a database or other digital storage formats, such as structured formats like JSON and XML, to store the encrypted information. The encrypted information will be used in subsequent processes, and only authorized systems and users can decrypt and access the original information.

[0078] Furthermore, the encrypted spatiotemporal information E(T) will be embedded in the trademark. During the trademark design process, this spatiotemporal information, as part of the encrypted data, is embedded into the trademark's design area through an appropriate encoding method. This allows the trademark to not only function as a brand identifier but also to contain the product's temporal and spatial information. This information embedding method enables effective tracking of the product at every stage of its circulation process, while simultaneously ensuring the trademark's anti-counterfeiting function.

[0079] S3. The encrypted spatiotemporal information is mapped using manifold theory, and the encrypted spatiotemporal information is mapped onto the two-dimensional plane of the trademark using a manifold embedding algorithm, thereby realizing the effective carrying of information in the trademark space.

[0080] Mapping encrypted spatiotemporal information using manifold theory is a key step in embedding product spatiotemporal information into a trademark. This step occurs immediately after the collection and encryption of the spatiotemporal information, ensuring that the product's spatiotemporal information can be effectively contained within the two-dimensional space of the trademark design. In this process, a manifold embedding algorithm is used to map the encrypted spatiotemporal information from a high-dimensional space onto the two-dimensional plane of the trademark. Through this mapping process, the product's spatiotemporal information retains its inherent geometric characteristics while adapting to the spatial requirements of the trademark.

[0081] Generally, manifold embedding algorithms are effective methods for mapping high-dimensional data to low-dimensional spaces. In this invention, we utilize manifold theory, particularly the Isomap algorithm or the t-SNE algorithm, to embed encrypted spatiotemporal information into the two-dimensional design plane of the trademark. This method not only minimizes information distortion but also ensures that the mapped spatiotemporal information is effectively carried within the trademark space.

[0082] As an alternative, the manifold mapping method used in this embodiment achieves this by optimizing the objective function. Optimizing the objective function balances the redundancy of spatiotemporal information, the richness of information (entropy value), and the simplicity of trademark design, thereby enabling spatiotemporal information to be efficiently and rationally distributed in the trademark space.

[0083] Specifically, the objective function can be expressed in the following form:

[0084]

[0085] In the formula, Information Redundancy represents the spatiotemporal information redundancy, and the optimization objective is to minimize redundancy; I entropy S is the entropy of spatiotemporal information, used to measure the richness of information; designTo achieve simplicity in trademark design, the optimization objective is to minimize complexity; J represents the optimization objective function; α represents the weight coefficient related to the redundancy of spatiotemporal information in the optimization objective function; β represents the weight coefficient related to the richness (entropy) of spatiotemporal information and the simplicity of trademark design in the optimization objective function.

[0086] By optimizing the objective function, the manifold mapping process can effectively embed information into the trademark plane while ensuring that the spatiotemporal geometric features are not lost, and at the same time avoid the excessive complexity of the trademark graphic.

[0087] In one possible implementation, the manifold embedding algorithm optimizes the mapping process by calculating the distance between the encrypted spatiotemporal data points. The distances involved are typically Euclidean distances, calculated using the following formula for each pair of spatiotemporal information data points T. i and T j Distance between:

[0088] D(T i ,T j )=||T i -T j ||2;

[0089] In the formula, T i and T j For the i-th and j-th data items in the spatiotemporal information; D(T) i ,T j ) represents spatiotemporal information T i and T j The Euclidean distance between them.

[0090] Specifically, through manifold embedding algorithms, the mapping of spatiotemporal data can preserve the relationships between information points while compressing high-dimensional data into a two-dimensional plane. The optimized information is then distributed effectively in the trademark space. This optimized distribution is further adjusted using manifold algorithms to ensure optimal utilization of the trademark space, enabling the trademark to not only carry sufficient spatiotemporal information but also maintain its visual recognizability.

[0091] In some embodiments, the mapped spatiotemporal information is optimized by designing a spatiotemporal information carrying area. The selection of the area is based on factors such as the shape, size, and visual effect of the trademark. During the design process, appropriate areas are selected to embed the spatiotemporal information according to the overall design style and requirements of the trademark, ensuring that the trademark can both carry information and maintain aesthetics.

[0092] S4. Embed the mapped spatiotemporal information into the trademark to ensure that the trademark can carry sufficient spatiotemporal information of the goods without affecting its recognizability and aesthetics;

[0093] Through the aforementioned steps of collecting, encrypting, and mapping spatiotemporal information using manifold theory, the product's spatiotemporal information has been encrypted and transformed into a two-dimensional representation suitable for trademark design. The next step is to embed this mapped spatiotemporal information into the trademark. This step ensures that the trademark can carry sufficient spatiotemporal information about the product without compromising its recognizability and aesthetics.

[0094] Generally, a trademark is not merely a product identifier; it should also be able to carry necessary product information. In this invention, the embedding of spatiotemporal information must ensure the trademark's visual appeal while simultaneously conveying sufficient spatiotemporal information about the product. Therefore, it is essential to precisely design appropriate areas within the trademark graphic to accommodate this information. Through a well-designed system, the trademark achieves a balance between functionality and visual aesthetics.

[0095] Alternatively, in this embodiment, embedding spatiotemporal information into the trademark does not interfere with its identifying function. Typically, the basic function of a trademark is to ensure that consumers can quickly identify and remember the brand of a product. Therefore, when selecting the area to carry spatiotemporal information, factors such as the shape, size, and visual effect of the trademark need to be considered. The trademark design must ensure that the carrying of spatiotemporal information does not affect the visual clarity and recognizability of the trademark.

[0096] Specifically, in this embodiment, there are multiple options for embedding spatiotemporal information in the trademark. For example, the information can be embedded in the form of a QR code or barcode. These information carriers are combined with the trademark's graphic elements, and relevant product information can be obtained by scanning. The size and position of the QR code and barcode need to be optimized according to the specific design of the trademark to ensure effective reading of the information without affecting the appearance of the trademark.

[0097] In one possible implementation, the process of embedding spatiotemporal information into a trademark involves two key steps: information area selection and information carrying method design.

[0098] The area within a trademark that carries spatiotemporal information requires precise selection. When choosing this area, the shape and size of the trademark are the first considerations. The size of the information-carrying area should be sufficient to accommodate all the encrypted spatiotemporal information while maintaining the trademark's clarity. This area is typically chosen at the edge of the trademark or in a location that does not affect the core identifying elements. The core area of ​​a trademark usually includes the brand logo, trademark name, etc., and the area carrying the spatiotemporal information should avoid covering these key parts.

[0099] Alternatively, the area carrying spatiotemporal information can be automatically selected through optimization algorithms. These algorithms dynamically select the optimal area based on the overall layout of the trademark design to ensure that the carrying of spatiotemporal information does not affect the visual effect of the trademark.

[0100] There are several possible ways to carry spatiotemporal information. In some embodiments, information can be embedded in the trademark via QR codes, barcodes, or micro-patterns. QR codes and barcodes can typically carry a large amount of information and have a high recognition rate. By scanning a QR code or barcode, consumers can immediately obtain key information such as the product's production time, production batch, and logistics route.

[0101] Specifically, during the design process, the size and position of the QR code or barcode should be adjusted according to the shape and size of the trademark. Generally, the QR code should not be too large to avoid affecting the trademark's legibility. At the same time, the QR code should coordinate with the trademark's color scheme to avoid design conflicts.

[0102] In some embodiments, in addition to QR codes and barcodes, spatiotemporal information can also be embedded in the trademark using methods such as digital watermarks and pattern coding. Digital watermarks can be embedded in the background of the trademark without affecting its main visual elements. Such technologies can further enhance the anti-counterfeiting capabilities of trademarks.

[0103] When embedding spatiotemporal information into a trademark, the selection of the embedding area is one of the keys to optimizing the trademark design. Assume the area of ​​the trademark design region is S. design A portion of this area will be used to store spatiotemporal information; the area of ​​this region is S. info Therefore, the proportion of the information carrying area can be expressed by the following formula:

[0104]

[0105] In the formula, S info S represents the area used to carry spatiotemporal information; design This indicates the total area of ​​the entire trademark design area; Area Ratio indicates the area ratio between the information carrying area and the trademark design area.

[0106] This ratio should generally be kept within a reasonable range to ensure that spatiotemporal information does not excessively occupy trademark design space and affect the trademark's recognizability.

[0107] The embedding of spatiotemporal information may include multiple small areas or graphic elements, each of which can carry different types of information (such as production batch, production time, logistics route, etc.). The size and position of each area can be dynamically adjusted according to the specific trademark design to ensure the aesthetics of the overall design and the effective delivery of information.

[0108] S5. Update the spatiotemporal information in the trademark in real time, and ensure the accuracy and completeness of the embedded spatiotemporal information throughout the circulation process according to the commodity circulation status.

[0109] Real-time updates of spatiotemporal information are a crucial element; as the circulation status of goods constantly changes, the spatiotemporal information embedded in trademarks must be updated synchronously in a timely manner to ensure its accuracy and completeness. Through real-time updates, the circulation status of goods can be reflected in the trademark information, ensuring that consumers, all parties in the supply chain, and related parties obtain the latest product information.

[0110] Generally, goods go through different stages and links during circulation, such as production, warehousing, transportation, and sales, and their status changes constantly. To ensure that the spatiotemporal information embedded in the trademark reflects the latest status of the goods, it is necessary to use Internet of Things (IoT) technology to achieve real-time monitoring of the goods' circulation status. This technology allows for dynamic tracking of information such as the goods' transportation routes, inventory status, and sales channels, ensuring that the spatiotemporal information in the trademark remains consistent with the actual circulation status of the goods.

[0111] As an alternative, real-time updated spatiotemporal information is not limited to the product's geographical location, but can also include various dynamic information such as the product's storage status, transportation method, and sales progress. Real-time updates of this information can further enhance the trademark's identification and anti-counterfeiting capabilities.

[0112] Specifically, at different stages of the commodity circulation process, IoT devices will collect real-time status information of the goods, including but not limited to the transportation route, transportation time, and arrival location. For spatiotemporal information already embedded in the trademark, this real-time information will be automatically synchronized and updated to ensure that the information displayed on the trademark remains accurate and up-to-date. This process can be completed synchronously through automated systems and databases.

[0113] In one possible implementation, the collected information on the status of commodity circulation is matched with the spatiotemporal information embedded in the trademark through a dedicated update system, and dynamically adjusted according to changes in commodity circulation. This mechanism ensures that trademark information is not outdated, avoiding potential misleading and inaccurate information due to delays.

[0114] The spatiotemporal information embedded in the trademark is updated in real time using a technical architecture that includes IoT devices, an automated data synchronization system, and a trademark embedding system. IoT devices acquire real-time information about the circulation status and location of goods through sensors, GPS positioning, and RFID tags. Sensors can be embedded in product packaging to track the goods' transportation routes, warehouse locations, and inventory status. All circulation status information is transmitted in real-time to the product information management system via the network.

[0115] A key part of the real-time update process is the synchronization of commodity circulation status information. Commodity circulation status information S flow Defined as a set of data, including but not limited to the transportation route P of the goods.trans Warehouse Status S storage Sales channel information C sales wait.

[0116] S flow ={P trans ,S storage C sales};

[0117] In the formula, P trans This refers to the transportation route information for the goods, including the mode of transport and transportation time; S storage This refers to the storage status of the goods, including the current inventory quantity and location; C sales This refers to the sales status of the goods, including sales progress and sales channels; S flow This refers to information on the status of commodity circulation.

[0118] In one implementation, this circulation status information is updated in a timely manner to the trademark embedding system through a real-time data acquisition and processing system, ensuring that new commodity circulation status data is updated promptly. The spatiotemporal information of the trademark will be adjusted accordingly based on changes in the commodity status, thereby ensuring that the spatiotemporal information displayed in the trademark accurately reflects the commodity circulation process.

[0119] To ensure the accuracy and completeness of the spatiotemporal information in the trademark, the real-time update mechanism will update the information based on the status of commodity circulation. flow Make the corresponding updates. Assume the spatiotemporal information of the trademark is T. info Furthermore, the spatiotemporal information in the trademark will be updated as the commodity circulation status changes, and the updated spatiotemporal information T′ info This can be expressed by the following formula:

[0120] T′ info =f(T) info ,S flow );

[0121] In the formula, T′ info Represents the updated spatiotemporal information; T info This indicates the spatiotemporal information initially embedded in the trademark; S flow is the commodity circulation status information; f is the mapping function, which matches and updates the commodity circulation status information with the trademark spatiotemporal information.

[0122] Alternatively, the function f can dynamically adjust the spatiotemporal information in the trademark based on data such as the product's transportation route, storage status, and sales channels. This process ensures the real-time nature and accuracy of the product information.
