[0077] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. However, it should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present disclosure. In the following detailed description, for ease of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present disclosure. However, it is apparent that one or more embodiments may also be implemented without these specific details. In addition, in the following description, descriptions of known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present disclosure.

[0078] The terms used herein are only for describing specific embodiments and are not intended to limit the present disclosure. The terms "comprise", "include", etc. used herein indicate the existence of the features, steps, operations and / or components, but do not exclude the existence or addition of one or more other features, steps, operations or components.

[0079] All terms (including technical and scientific terms) used herein have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein should be interpreted as having a meaning consistent with the context of this specification, and should not be interpreted in an idealized or overly rigid manner.

[0080] When using expressions such as "at least one of A, B, and C, etc.", they should generally be interpreted according to the meaning of the expression commonly understood by those skilled in the art (for example, "a system having at least one of A, B, and C" should include but is not limited to a system having A alone, B alone, C alone, A and B, A and C, B and C, and / or A, B, C, etc.).

[0081] It should be noted that the precious metal management method, device, electronic device, storage medium and program product provided in the present disclosure relate to the field of Internet of Things technology. The precious metal management method, device, electronic device, storage medium and program product provided in the embodiments of the present disclosure can be applied to the financial field or any field other than the financial field. For example, the precious metal management method, device, electronic device, storage medium and program product provided in the embodiments of the present disclosure can be applied to the precious metal management business in the financial field. The present disclosure does not limit the application field of the precious metal management method, device, electronic device, storage medium and program product.

[0082] In the technical solution of the present disclosure, the collection, storage, use, processing, transmission, provision, disclosure and application of user personal information involved comply with the provisions of relevant laws and regulations, take necessary confidentiality measures, and do not violate public order and good morals.

[0083] In one example, radio frequency identification (RFID) tags are used to identify precious metals. When the precious metals are counted, the RFID tags are also used for counting. For example, for a certain precious metal, when its RFID tag is consistent with the data in the management system, it is considered that the counting has passed. However, RFID tags are generally set on the packaging of precious metals. Therefore, RFID tags are separated from the precious metal bodies. By counting RFID tags, it is impossible to find out whether the precious metal bodies have been replaced, which is easy to cause discrepancies between accounts and actuals.

[0084] In view of this, an embodiment of the present disclosure provides a precious metal management method, which includes: obtaining first surface texture information of the precious metal to be registered; determining the first product feature of the precious metal to be registered based on the difference between the first surface texture information and the preset sample texture information; obtaining a first radio frequency identification tag assigned to the precious metal to be registered; associating the first radio frequency identification tag and the first product feature to obtain a product label; and registering the precious metal to be registered based on the product label.

[0085] In the disclosed embodiment, when registering, the product label containing the physical characteristics of the precious metals is recorded, so that when the precious metals are counted, the inventory can be performed according to the product label containing the physical characteristics of the precious metals. For example, when counting, the product information of the precious metals to be counted can be obtained from the management system, and the second product characteristics of the precious metals to be counted can be obtained by the above-mentioned method of obtaining the first product characteristics. For example, the second surface texture information of the precious metals to be counted is first obtained by scanning, and then the second product characteristics are generated according to the difference between the second surface texture information and the preset sample texture information. Afterwards, the first product characteristics of the precious metals to be counted can be parsed from the product label. When the first product characteristics match the second product characteristics, it can be determined that the precious metals to be counted have not been replaced, thereby ensuring the consistency between the account and the actual situation.

[0086] Figure 1 The application scenario diagram of the precious metal management method, device, electronic device, storage medium and program product according to the embodiment of the present disclosure is schematically shown. Figure 1 As shown, the application scenario 100 according to this embodiment may include terminal devices 101, 102, 103, a network 104, and a server 105. The network 104 is used to provide a medium for a communication link between the terminal devices 101, 102, 103 and the server 105. The network 104 may include various connection types, such as wired, wireless communication links or optical fiber cables, etc.

[0088] The terminal devices 101 , 102 , and 103 may be various electronic devices having a display screen and supporting web browsing, including but not limited to smart phones, tablet computers, laptop computers, and desktop computers.

[0089] The server 105 may be a server that provides various services, such as a background management server (only an example) that provides support for websites browsed by users using the terminal devices 101, 102, and 103. The background management server may analyze and process the received data such as user requests, and feed back the processing results (such as web pages, information, or data obtained or generated according to user requests) to the terminal device.

[0090] It should be noted that the precious metal management method provided in the embodiment of the present disclosure can generally be executed by the server 105. Accordingly, the precious metal management device provided in the embodiment of the present disclosure can generally be set in the server 105. The precious metal management method provided in the embodiment of the present disclosure can also be executed by a server or server cluster that is different from the server 105 and can communicate with the terminal devices 101, 102, 103 and / or the server 105. Accordingly, the precious metal management device provided in the embodiment of the present disclosure can also be set in a server or server cluster that is different from the server 105 and can communicate with the terminal devices 101, 102, 103 and / or the server 105.

[0091] It should be understood that Figure 1 The number of terminal devices, networks and servers in the embodiment is only for illustration. Any number of terminal devices, networks and servers may be provided according to implementation requirements.

[0092] The following will be based on Figure 1 The scene described by Figure 2 The precious metal management method of the disclosed embodiment is described in detail.

[0093] Figure 2 One of the flowcharts of the precious metal management method according to an embodiment of the present disclosure is schematically shown. Figure 2 As shown, the precious metal management method of this embodiment includes steps S210 to S250.

[0094] It should be noted that although Figure 2 The steps in the figure are shown in sequence as indicated by the arrows, but the steps are not necessarily executed in sequence in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order restriction on the execution of the steps, and they can be executed in other orders. Moreover, at least some of the steps in the figure may include multiple sub-steps or multiple stages, and these sub-steps or stages are not necessarily executed at the same time, but can be executed at different times, and their execution order is not necessarily sequential, but can be executed in turn or alternately with other steps or at least a part of the sub-steps or stages of other steps.

[0095] In step S210, first surface texture information of the precious metal to be registered is obtained.

[0096] In the embodiment of the present disclosure, the precious metal to be registered may include precious metal products such as gold bars, gold bricks, etc. The first surface texture information may include a surface texture image of the precious metal to be registered.

[0097] Optionally, the first surface texture information of the precious metal may be acquired by scanning at least one surface of the precious metal to be registered. For example, a surface of the precious metal to be registered engraved with a specific pattern may be scanned. The specific pattern may include, for example, a product logo (LOGO) or the like.

[0098] In step S220, a first product feature of the precious metal to be registered is determined according to the difference between the first surface texture information and the preset sample texture information.

[0099] In the embodiments of the present disclosure, the surface texture images of the same type of precious metals are roughly the same, but due to the special properties of precious metal products, such as the soft texture of gold products, during the production process, there are often slight differences in the surface texture images of different precious metals. Therefore, this difference is similar to the "fingerprint" of the precious metal and can characterize the physical properties of the precious metal.

[0100] In the embodiment of the present disclosure, a reference texture image can be configured for a type of precious metal, and the reference texture image can be used as the preset sample texture information. At this time, the difference between the first surface texture information and the preset sample texture information can refer to: the image difference between the surface texture image of the precious metal to be registered and the reference texture image.

[0101] In the disclosed embodiment, the first product feature of the precious metal to be registered is determined based on the difference between the first surface texture information and the preset sample texture information. For example, the above-mentioned image difference can be used as the first product feature of the precious metal to be registered. In the disclosed embodiment, the main reasons for the difference include: product workmanship problems and defects caused by scratches or bumps. These small differences are difficult to fully reproduce during the recasting process, so by recording these features, the product itself can be prevented from being replaced and recast.

[0102] In this way, the first product feature can not only characterize the physical properties of the precious metal to be registered, but also, since the part of the first surface texture information that is identical to the preset sample texture information is omitted, the amount of data of the first product feature can be greatly reduced, which is beneficial to subsequent calculation and storage.

[0103] In step S230, a first radio frequency identification tag (RFID) assigned to the precious metal to be registered is acquired.

[0104] In step S240, the first radio frequency identification tag is associated with the first product feature to obtain a product tag.

[0105] In the disclosed embodiment, a unique first RFID tag may be assigned to each precious metal to be registered. Optionally, identification information (TID) may be extracted from the first RFID tag, and the extracted identification information may be combined with the first product feature to obtain a product tag. In this way, the product tag not only contains the identification information, but also contains the physical properties of the precious metal to be registered (i.e., the first product feature).

[0106] In step S250, the precious metal to be registered is registered according to the product label.

[0107] In the disclosed embodiment, the product label may be stored in the management system for registration.

[0108] In the disclosed embodiment, when registering, the product label containing the physical characteristics of the precious metals is recorded, so that when the precious metals are counted, the inventory can be performed according to the product label containing the physical characteristics of the precious metals. For example, when counting, the product information of the precious metals to be counted can be obtained from the management system, and the second product characteristics of the precious metals to be counted can be obtained by the above-mentioned method of obtaining the first product characteristics. For example, the second surface texture information of the precious metals to be counted is first obtained by scanning, and then the second product characteristics are generated according to the difference between the second surface texture information and the preset sample texture information. Afterwards, the first product characteristics of the precious metals to be counted can be parsed from the product label. When the first product characteristics match the second product characteristics, it can be determined that the precious metals to be counted have not been replaced, thereby ensuring the consistency between the account and the actual situation.

[0109] Combine the following Figures 2 to 9 The precious metal management method of the embodiment of the present disclosure is further explained.

[0110] In some specific embodiments, the first surface texture information includes a first matrix image obtained by laser scanning the first surface of the precious metal to be registered. In the embodiment of the present disclosure, the first surface can be, as described above, a side surface of the precious metal to be registered on which a specific pattern is provided. In the embodiment of the present disclosure, by laser scanning the surface of the precious metal to be registered, a surface image with high precision can be obtained, and the first matrix image generated based on this can better characterize the surface texture of the precious metal to be registered.

[0111] Optionally, the first matrix image may include a two-dimensional matrix image. For example, a certain landmark position may be selected from the surface of the precious metal to be registered, and this position may be used as the first reference position of the first matrix image, and then the first matrix image may be generated according to the height difference between other positions and the first reference position. For example, in the first matrix image, each pixel may include the height difference between the position corresponding to the pixel and the first reference position.

[0112] In some specific embodiments, the preset sample texture information includes a second matrix image. In the embodiment of the present disclosure, the second matrix image may be a two-dimensional matrix image pre-set for a type of precious metal and capable of characterizing the texture of the second surface of the type of precious metal, wherein the second surface may be the same as the first surface mentioned above, and both are one side surface of the precious metal on which a specific pattern is provided.

[0113] For example, for a type of precious metal A, a second matrix image B can be set for the type of precious metal, and the second matrix image can characterize the ideal texture of the surface of the type of precious metal engraved with the LOGO. When registering precious metals, the surface of the precious metal to be registered with the same LOGO engraved can be scanned by laser to obtain the first matrix image. At this time, the first matrix image is roughly the same as the second matrix image, but due to the characteristics of the precious metal, there are slight differences between the first matrix image and the second matrix image. Therefore, the first product feature can be determined by the slight difference between the first matrix image and the second matrix image.

[0114] For example, a second reference position may be provided in the second matrix image, and the second reference position is located at the same position as the first reference position in the image. For example, in the first reference image, pixel X is used as the first reference position, and correspondingly, in the second reference image, pixel X is used as the second reference position. Each pixel in the second matrix image may include a height difference between the position corresponding to the pixel and the reference position in the second matrix image.

[0115] Figure 3 A flowchart of generating a first product feature according to an embodiment of the present disclosure is schematically shown. Figure 3 As shown, step S220 includes step S221 and step S223.

[0116] In step S221, a difference value matrix image is generated according to difference values ​​of at least some pixels in the first matrix image and the second matrix image.

[0117] Figure 4a The flowchart of generating a difference value matrix image according to an embodiment of the present disclosure is schematically shown. Figure 4a As shown, in some specific embodiments, step S221 includes steps S2211 to S2213.

[0118] In step S2211, the first matrix image is horizontally corrected.

[0119] In the embodiment of the present disclosure, the placement position of the precious metal to be registered may be tilted or not completely aligned. In this case, pixel points that can be used for correction in the first matrix image, such as center points, corner points, or LOGO pixels, etc., can be extracted, so that the first matrix image can be horizontally corrected using these pixel points as a reference.

[0120] For example, to prevent the horizontal correction caused by the tilt of the platform, an adjustment may be made according to a certain slope, so that the first matrix image is consistent with the expectation to the greatest extent.

[0121] In step S2212, the key positions in the horizontally corrected first matrix image are extracted.

[0122] In the embodiment of the present disclosure, the key position in the first matrix image can be extracted for comparison with the second matrix image. For example, the position of the corresponding LOGO in the first matrix image can be extracted and used as the key position or the surrounding area.

[0123] In step S2213, a difference value matrix image is generated according to the difference values ​​of the pixel points at the key position and the corresponding position in the second matrix image.

[0124] In the embodiment of the present disclosure, the difference value of each pixel in the first matrix image and the second matrix image may be compared, for example, Figure 4b A schematic diagram of a first matrix image in an embodiment of the present disclosure is schematically shown. Figure 4c A schematic diagram of a second matrix image in an embodiment of the present disclosure is schematically shown. Figure 4d The schematic diagram of the difference value matrix image in the embodiment of the present disclosure is schematically shown, combined with Figure 4b to Figure 4d As shown, for the pixel (2,9) in the first matrix image, the height difference between it and the first reference position is "5", and for the pixel (2,9) in the second matrix image, the height difference between it and the second reference position is "3", then the difference value of the pixel (2,9) in the first matrix image and the second matrix image is "2". At this time, the pixel (2,9) in the difference value matrix image can be generated based on the difference value, and the value of the pixel (2,9) is "2".

[0125] In step S222, non-zero elements in the difference value matrix image are extracted, thereby reducing the amount of data and saving computing and storage resources.

[0126] In step S223, the extracted non-zero elements are compressed to obtain the first product feature. By compressing the non-zero elements, the amount of data can be further reduced.

[0127] Optionally, while data compression is being performed, non-zero elements may also be encrypted, thereby improving data security.

[0128] Optionally, the data of each difference pixel (or called deviation point pixel) may be combined and encrypted uniformly to obtain the first product feature. Each difference pixel may also be encrypted one by one, and the encryption results may be integrated into one to obtain the first product feature. Multiple encryption results may be generated).

[0129] Figure 5 The flowchart of generating product labels according to an embodiment of the present disclosure is schematically shown. Figure 5 As shown, in some specific embodiments, step S240 includes steps S241 to S243.

[0130] In step S241, the product code information of the precious metal to be registered and the identification information in the first radio frequency identification tag are obtained.

[0131] In the embodiment of the present disclosure, the product code information of the precious metal to be registered can be directly obtained from the relevant information of the precious metal to be registered.

[0132] In step S242, the identification information, the product coding information and the first product feature are combined.

[0133] In the embodiments of the present disclosure, the identification information, the product coding information and the first product feature can be combined by concatenating the identification information, the product coding information and the first product feature in a predetermined order. Optionally, when the identification information, the product coding information and the first product feature are concatenated in a predetermined order, corresponding identifiers can be set for the identification information, the product coding information and the first product feature to facilitate distinction and parsing.

[0134] In step S243, the combined result is encrypted to obtain a product label. For example, a homomorphic encryption algorithm may be used for encryption.

[0135] Figure 6 The flowchart of performing registration according to an embodiment of the present disclosure is schematically shown. Figure 6 As shown, in some specific embodiments, step S250 includes steps S251 to S254.

[0136] In step S251, the product tag is written into the first radio frequency identification tag to obtain a second radio frequency identification tag.

[0137] The entire product label can be written into the first RFID tag, or only the first product feature used to constitute the product label can be written into the first RFID tag. When the entire product label is written into the first RFID tag, the data is more complete and more reliable. When only the first product feature used to constitute the product label is written into the first RFID tag, the data volume is lower, which is conducive to saving storage space.

[0138] In step S252, the precious metal to be registered is weighed.

[0139] In step S253, product information is generated according to the weighing result and the product label.

[0140] In the disclosed embodiment, due to the characteristics of precious metals, there are slight differences in the weights of different precious metals in the same category, and the physical properties of the precious metals to be registered can also be characterized by weighing.

[0141] In the embodiment of the present disclosure, in addition to the weighing results and product labels, the product information may also include product coding information, product size, product delivery status, first product characteristics, and identification information, etc. The specific information may be determined according to actual needs and is not limited here.

[0142] Optionally, the weight of the precious metal to be registered can be used for review during the inventory process of the precious metal to be registered, which will be described in detail below and will not be elaborated here.

[0143] In step S254, the second RFID tag and the product information are bound to the metal to be registered for registration.

[0144] In the disclosed embodiment, a second RFID tag may be set on the packaging of the precious metal, the product information may be stored in a management system, and the second RFID tag and the product information may be associated with the precious metal to be registered for binding, thereby completing the registration of the precious metal to be registered.

[0145] When taking inventory, the product label can be parsed from the second RFID label, and the identified product label can be compared with the product label in the product information stored in the management system to perform a preliminary inventory. The preliminary inventory can be used to preliminarily verify whether the inventory is consistent with the information recorded in the management system. When the preliminary inventory is completed, the precious metals to be counted can be scanned to generate the second surface texture information, etc., for a secondary inventory to prevent discrepancies between the account and the actual due to product replacement and other reasons.

[0146] Next, the process of performing secondary inventory through product labels during the inventory process is explained.

[0147] In some specific embodiments, Figure 7 The second flowchart of the precious metal management method according to the embodiment of the present disclosure is schematically shown. Figure 7 As shown, the precious metal management method further includes steps S310 to S350.

[0148] In step S310, product labels of the precious metals to be counted are obtained.

[0149] In the disclosed embodiment, the product label can be parsed from the second RFID tag by using RFID technology, or the product information can be extracted from the management system to parse the product label.

[0150] In step S320, the precious metal to be counted is scanned to obtain second surface texture information of the precious metal to be counted.

[0151] In step S330, a second product feature of the precious metal to be counted is determined according to the difference between the second surface texture information and the preset sample texture information.

[0152] In the disclosed embodiment, the second product feature can be obtained by a method similar to or the same as that of obtaining the first product feature. For example, the surface of the precious metal to be counted with a specific pattern can be scanned by laser to obtain the second surface texture information, and the second surface texture information can optionally include a third matrix image, and the third matrix image can include a two-dimensional matrix image.

[0153] By comparing the third matrix image with the preset sample texture information (i.e., the second matrix image), the difference value of each pixel can be extracted, and then the corresponding difference value matrix image can be generated. After that, the second product feature can be generated by compression, encryption, and combination with identification information.

[0154] In step S340, the product tag is parsed to extract the first product feature.

[0155] In step S350, when the second product feature matches the first product feature, it is determined that the inventory is passed.

[0156] In the disclosed embodiment, when the second product feature is the same as the first product feature, it means that the entity of the precious metal to be counted is consistent with the entity information recorded when the precious metal is registered. Therefore, it can be explained that no replacement has occurred during the management process, ensuring the consistency between the account and the actual situation.

[0157] Optionally, when the second product feature is inconsistent with the first product feature, in addition to replacement, it may also be damaged by collision. Therefore, manual intervention can be initiated at this time, and the manual intervention can be used to determine which situation is the case based on the specific situation.

[0158] In the embodiment of the present disclosure, when the second product feature is inconsistent with the first product feature due to a slight bump, the first product feature (and the second radio frequency tag) stored in the management system may be updated.

[0159] Figure 8 The third flowchart of the precious metal management method according to the embodiment of the present disclosure is schematically shown. Figure 8 As shown, in some specific embodiments, before the secondary review, that is, before step S320, the precious metal management method also includes a preliminary inventory process, and the preliminary inventory process includes steps S410 to S440.

[0160] In step S410, product information of registered precious metals is obtained.

[0161] In the embodiment of the present disclosure, currently stored product information may be acquired from the management system to obtain product information of registered precious metals.

[0162] In step S420, the product label in the product information is extracted to obtain a first product label of each precious metal.

[0163] In the embodiment of the present disclosure, as described above, the product information may consist of a product label and a weighing result. Therefore, the product label in the product information may be parsed by a decryption algorithm corresponding to the encryption algorithm described above.

[0164] In step S430, all the second RFID tags of the precious metals in the library are scanned, and the product tags in the second RFID tags are extracted to obtain the second product tag of each precious metal.

[0165] In the disclosed embodiment, the product tag may be parsed from the second RFID tag by using RFID technology.

[0166] In step S440, a preliminary inventory is performed based on the extracted first product labels and second product labels.

[0167] In the disclosed embodiment, for the precious metals to be counted, when the first product label and the second product label are consistent, it is preliminarily indicated that the inventory is consistent with the record. At this time, the precious metals to be counted can be scanned for the above-mentioned secondary inventory. When the first product label and the second product label are inconsistent, it means that the inventory is different from the record. At this time, the outbound record can be retrieved. For example, when the product information includes the above-mentioned outbound status, the outbound status can be extracted to determine whether the inconsistency between the first product label and the second product label is caused by product outbound or label shedding, so as to verify the reason for the inconsistency between the two.

[0168] Fig. 9 A flowchart of a preliminary inventory according to an embodiment of the present disclosure is schematically shown. Fig. 9 As shown, in some specific embodiments, step S440 includes steps S441 to S444.

[0169] In step S441, when the first product label and the second product label of at least one precious metal do not match, the precious metal is determined to be a metal to be verified.

[0170] In step S442, the weight of all the precious metals currently in the library is obtained to obtain a first weight.

[0171] In step S443, the weight of the metal to be verified is extracted from the first product label of the metal to be verified to obtain a second weight.

[0172] In step S444, it is determined whether the metal to be verified is an abnormal precious metal based on the first weight and the second weight.

[0173] For example, the original weight of the precious metal in the warehouse is D, and the weight of precious metal E is E1. When precious metal E is taken out of the warehouse, the current weight of all precious metals in the warehouse is F. Since the weight of precious metal E is unique, the weights of different precious metals are not the same. Therefore, when F=D-E1, it means that the precious metal taken out of the warehouse is indeed precious metal E. Otherwise, it means that other precious metals may have been taken out of the warehouse. At this time, it can be determined based on the missing weight to determine which precious metal is not in the warehouse, and then manual intervention can be initiated to further verify the specific situation.

[0174] Based on the above precious metal management method, the present disclosure also provides a precious metal management device. Fig.10 The device is described in detail.

[0175] Fig.10 The structure block diagram of the precious metal management device according to the embodiment of the present disclosure is schematically shown. Fig.10 As shown, the precious metal management device 800 of this embodiment includes a first acquisition module 1010 , a first processing module 1020 , a second acquisition module 1030 , a second processing module 1040 and a registration module 1050 .

[0177] The first processing module 1020 is used to determine the first product feature of the precious metal to be registered according to the difference between the first surface texture information and the preset sample texture information. In one embodiment, the first processing module 1020 can be used to execute the step S220 described above, which will not be repeated here.

[0178] The second acquisition module 1030 is used to acquire the first RFID tag assigned to the precious metal to be registered. In one embodiment, the second acquisition module 1030 can be used to execute the step S230 described above, which will not be described in detail here.

[0181] In the disclosed embodiment, when registering, the product label containing the physical characteristics of the precious metals is recorded, so that when the precious metals are counted, the inventory can be performed according to the product label containing the physical characteristics of the precious metals. For example, when counting, the product information of the precious metals to be counted can be obtained from the management system, and the second product characteristics of the precious metals to be counted can be obtained by the above-mentioned method of obtaining the first product characteristics. For example, the second surface texture information of the precious metals to be counted is first obtained by scanning, and then the second product characteristics are generated according to the difference between the second surface texture information and the preset sample texture information. Afterwards, the first product characteristics of the precious metals to be counted can be parsed from the product label. When the first product characteristics match the second product characteristics, it can be determined that the precious metals to be counted have not been replaced, thereby ensuring the consistency between the account and the actual situation.
