Description

SYSTEM AND METHOD FOR DETERMINING GRADE OF A PRODUCT

FIELD OF DISCLOSURE

[0001] The present disclosure relates to determination of quality of a product. In particular, the present disclosure relates to a system and device for determining grade of a product based on their quality.

BACKGROUND OF THE DISCLOSURE

[0002] The background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.

[0003] Pricing of an agricultural product such as a crop is highly dependent on its quality as perceived by potential buyers. Very limited standard procedures exist for determining this quality. Further, the quality (interchangeably termed as grade herein) of a crop may vary widely, even for the same farmer, per factors such as weather patterns, time of sowing and reaping the crop etc. etc.

[0004] This lack of standard procedures and variation in grade of a crop gives a buying party stronger position in negotiations at a moment in time very high leeway, mostly to disadvantage of the other party. Mostly, it is a potential buyer who decides, by visual inspection primarily, how much grain is destroyed by pests, and if foreign particles are present, before offering the farmer a price. Buyers mostly operate in groups and once a grade is determined chances that another buyer may grade the crop higher are remote. However, the grading process is generally subjective and prone to error. Visual inspection relies too much on the buyer’s expertise. A buyer may be a middleman and may cheat farmers.

[0005] Grading of an agricultural crop is hence a serious bottleneck for farmers, given also the perishable nature of many crops and hence the desire of the farmer to sell his crop as early as possible. In a real market, when a farmer takes his or her crop to the market then the farmer may decide on the grade initially. However while buying, the buyers (who could be traders / middlemen) have the final word on the grade. The traders may get this bargaining power as they could make a group themselves and decide to give only specific offers to the farmer. So primarily the traders negotiate the price based on the perceived reduced quality of the crop and win the negotiation, as no other buyer would make a higher offer.

[0006] Hence there is a need in the art for a system and a hardware device that grades a crop in a transparent manner such that the participation in grading process is available to all the stakeholders and can be trusted. Further, the grading should be done by people whose expertise in such grading can be transparently evaluated continuously. The system should empower equally all involved in a negotiation, create a self-reliant farmer’s community, and give assurance to the buyers as well that grading provided fairly represents quality of the crop.

[00013] It is an object of the present disclosure to provide for an web interface based interactive system to grade a crop in a transparent manner, wherein the grade can be trusted and is available to all stakeholders in a negotiation.

[00014] It is an object of the present disclosure to provide for an web interface based interactive grading system through peers of the seller and all concerned stakeholders involved in the transaction to grade a crop wherein the graders are continuously encouraged to correctly and accurately grade a crop and those who do not are automatically used less and less by other stakeholders such as farmers and buyers.

[00015] It is an object of the present disclosure to provide for an web interface based interactive system to grade a crop that empowers equally all involved in a negotiation, creates a self-reliant farmer’s community, and gives assurance to the buyers as well that grading provided fairly represents quality of the crop.

SUMMARY [00016] The present disclosure pertains to a system for grading a product with regard to its quality. In particular, the present disclosure pertains to a system that provides reliable grade of a product (or of different products of different types/characteristics/properties/attributes) in a transparent manner to all stakeholders.

[00017] This summary is provided to introduce simplified concepts of a system to grade products. The system can be implemented to grade quality of different products and can be particularly useful to grade quality of different crops. This summary is not intended to identify key or essential features of the claimed subject matter, nor is it intended for use in determining/limiting the scope of the claimed subject matter.

[00018] In an aspect, the present disclosure provides for a system for determining grade of a product, said system comprising one or more processors coupled with a memory, said memory storing instructions which when executed by said one or more processors cause said system to:receive, at a server, from a first computing device associated with a first entity (FE), a first set of data packets indicative of a grade of said product as claimed by the FE;store, in a first database (DB) associated with said server, said at least a portion of the first set of data packets, and process said at least a portion of the first set of data packets to select, in real-time, any or both of at least one peer entity (PE) and at least one grading entity (GE) based on attributes associated with the product; and receive, at said server, a second set of data packets from a second computing device associated with the selected PE, and a third set of data packets from a third computing device associated with the selected GE, each of said first and second set of data packets being stored in a second DB associated with said server, and being indicative at least of actual grade of said product as assessed by said PE and/or GE based on at least a part of said attributes associated with the product.

[00019] The proposed system can further be configured to generate, at said server, a private key (PK) using customized unique identification number /unique identity (UID) for each of the selected PE, the selected GE, and the FE; and store, on a blockchain, at least a part of said first, second, and third set of data packets using corresponding private keys of FE, PE, and GR, wherein said stored second set of data packets are indicative at least of actual grade of said product as determined by the selected PE, and said stored third set of data packets are indicative at least of actual grade of said product as determined by the selected GE.

[00020] In an aspect, the first set of data packets can include quantity of said product, location of said product, price of said product, and expected time of pickup of said product. [00021] In another aspect, the PK can remain unchanged for the selected PE and the selected GE for any storing of said at least a part of said second and third set of data packets onto said blockchain. Alternatively, in another embodiment, the PK can change for the selected PE and the selected GE for any storing of said at least a part of said second and third set of data packets onto said blockchain.

[00022] In another aspect, the blockchain can be public or private.

[00023] In another aspect, the system can enable a second entity (SE) to, using a fourth computing device associated with the SE, search for one or more FE users, and upon selection of the FE, validate any or a combination of said grade of said product as claimed by the FE, and as assessed by any or a combination of said respective PE and GE using said blockchain. In an exemplary embodiment, the SE can be the selected GE. In another embodiment, in case the variance between the grade determined by the PE/GE and thegrade claimed by FE is above a pre determined threshold, said system enables the SE to verify said grade using said blockchain by means of a fourth set of data packets provided by a Second Grading Entity (SGE), said a fourth set of data packetsbeing indicative at least of actual grade of said product, and wherein at least a part of said fourth set of data packets is stored onto said blockchain. In yet another aspect, the system can be configured to rank any or a combination of the PE, the GE, and the SGE based on variance between grade accepted by the SE and the grades determined by each of the PE, the GE, and the SGE.

[00024] In another aspect, the product can be crop of a farmer, said FE being the farmer, said PE being a peer farmer, said GE being a crop grader, said second entity (SE) being a buyer of said crop, and said SGE being another crop grader.

[00025] The present disclosure can further pertain to a method for determining grade of a product, said method comprising receiving, at a server, from a first computing device associated with a first entity (FE), a first set of data packets indicative of a grade of said product as claimed by the FE;storing, in a first database (DB) associated with said server, said at least a portion of the first set of data packets, and process said at least a portion of the first set of data packets to select, in real-time, any or both of at least one peer entity (PE) and at least one grading entity (GE) based on attributes associated with the product receiving, at said server, a second set of data packets from a second computing device associated with the selected PE, and a third set of data packets from a third computing device associated with the selected GE, each of said first and second set of data packets being stored in a second DB associated with said server, and being indicative at least of actual grade of said product as assessed by said PE and/or GE based on at least a part of said attributes associated with the product generating, at said server, a private key (PK) using customized unique identification number /unique identity (UID) for each of the selected PE, the selected GE, and the FE; and storing, on a blockchain, at least a part of said first, second, and third set of data packets using corresponding private keys of FE, PE, and GR, wherein said stored second set of data packets are indicative at least of actual grade of said product as determined by the selected PE, and said stored third set of data packets are indicative at least of actual grade of said product as determined by the selected GE.

[00026] The technical problem addressed by the proposed invention is difficulty in fairly and reliably grading a crop in order to enable its sale (usually over an e -commerce platform/portal). To solve the technical problem, proposed invention creates a self-reliant community of farmers, grading experts and buyers. Various transactions pertaining to grading of one/ more crops are recorded using blockchain techniques so as to ensure they are immutable and traceable to the entities making them. The proposed system allows real-time assessment of crop grade based on attributes of the crop, photos submitted by the person wishing to get the crop graded, historical background/reliability/credibility profile of the person/user/entity person wishing to get the crop graded, attributes/parameters associates with the crop, season in which the respective crop is being graded, among many other parameters that can be analyzed through a plurality of engaged and communicatively coupled computing devices so as to enable the second and third entities/expert users to grade the respective crop of the first entity/user.

[00027] In an aspect, the present disclosure relates to a portable computing device implementing the above method, wherein the device can include a display screen with a camera attached thereto; an IOT (Internet of Things) sensing GSM device; and two paper rolling devices, wherein the camera can be used to take image of the product and the image undergoes processing for a first level of grading, based on which the IOT sensing GSM device obtains supporting data for a second level of grading, post which the two paper rolling devices can be used to benchmark the product as a third and final level of grading.

[00028] Within the scope of this application it is expressly envisaged that the various aspects, embodiments, examples and alternatives set out in the preceding paragraphs, in the claims and/or in the following description and drawings, and in particular the individual features thereof, may be taken independently or in any combination.

[00051] Various terms as used herein are shown below. To the extent a term used in a claim is not defined below, it should be given the broadest definition persons in the pertinent art have given that term as reflected in printed publications and issued patents at the time of filing.

[00052] In an aspect, present disclosure elaborates upon a system for determining grade of a product. The system can include one or more processors coupled with a memory. The memory can store instructions which when executed by the one or more processors can cause the system to: receive, from a first computing device associated with a first entity (FE), a first request (FR) comprising grade of the product as claimed by the FE; store, in a first database (DB), the FR and process the FR to select any or both of at least one peer entity (PE) and at least one grading entity (GE); receive a first feedback from a second computing device associated with the selected PE and a second feedback from a third computing device associated with the selected GE, each of the first and second feedbacks being stored in a second DB and indicative at least of actual grade of the product; generate a private key (PK) for each of the selected PE, the selected GE, and the FE; and log onto a blockchain at least a part of the FR and any or a combination of at least a part of the first and second feedbacks using corresponding private keys, the part logged of the first feedback being indicative at least of actual grade of the product as determined by the selected PE and the part logged of the second feedback being indicative at least of actual grade of the product as determined by the selected GE. [00053] In another aspect, the FR can include quantity of the product, location of the product, price of the product, and expected time of pickup of the product.

[00054] In yet another aspect, the FR can be processed in real-time to select any or both of the at least one Peer Entity (PE) and the at least one Grading Entity (GE).

[00055] In an aspect, the PK can remain unchanged for the selected PE and the selected GE for any logging of the at least a part of the first feedback and the at least a part of the second feedback onto the blockchain.

[00056] In another aspect, the PK can change for the selected PE and the selected GE for each logging of the at least a part of the first feedback and the at least a part of the second feedback onto the blockchain.

[00057] In yet another aspect, the blockchain can be public or private.

[00058] In an aspect, the system can enable a second entity (SE) to, using a fourth computing device associated with the SE, search for one or more first entity users and upon selection of the first entity, validate any or a combination of the grade of the product as claimed by the FE, the first feedback, and the second feedback using the blockchain.

[00059] In another aspect, the second entity can be the selected GE.

[00060] In yet another aspect, in case of variance above a pre -determined threshold between grade determined by the second entity and the actual grade, the system can enable the second entity to verify the grade using the blockchain by means of a third feedback provided by a Second Grading Entity (SGE) using a fifth computing device, wherein the SGE can be allocated by the system and the third feedback can be indicative at least of actual grade of the product, and wherein at least a part of the third feedback can be logged onto the blockchain, the part logged of the third FB indicative at least of actual grade of the product as determined by the SGE.

[00061] In an aspect, the system can rank any or a combination of the selected peer entity (PE), the grading entity (GE) and the second grading entity (SGE) based upon variance between grade accepted by the second entity and grades determined by the selected peer entity (PE), the selected grading entity (GE) and the second grading entity (SGE).

[00062] In another aspect, the product can be crop of a farmer, the FE can be the farmer, the at least one PE can be a peer farmer, the at least one GE can be a crop grader, the second entity (SE) can be buyer of the crop and the SGE can be another crop grader. [00063] In an aspect, present disclosure elaborates upon a method for determining grade of a product. The method can include steps of : receiving, at a computing device, from a first entity (FE), a first request (FR) comprising grade of the product as claimed by the FE; storing, at the computing device, the FR in a first database (DB) and processing, at the computing device, the FR to select any or both of at least one peer entity (PE) and at least one grading entity (GE); receiving, at the computing device, a first feedback from selected PE and a second feedback from selected GE, each of the first and the second feedbacks being stored in a second DB and indicative at least of actual grade of the product ; generating, at the computing device, a private key (PK) for each of the selected PE , the selected GE, and the FE; and logging onto a blockchain at least a part of the FR and any or a combination of at least a part of the first feedback and at least a part of the second feedback using corresponding private keys, the part logged of the first feedback indicative at least of actual grade of the product as determined by the selected PE and the part logged of the second feedback indicative at least of actual grade of the product as determined by the selected GE.

[00064] Various objects, features, aspects and advantages of the present disclosure will become more apparent from the following detailed description of preferred embodiments, along with the accompanying drawing figures in which like numerals represent like features.

[00065] In an exemplary embodiment elaborated herein, proposed invention can automate grading of a crop of a farmer / user (a user interchangeably termed as an entity and the farmer as a first entity FE) so as to facilitate its sale in a transparent and trustworthy manner. The grading can be performed by one/more peers of the farmer (interchangeably termed as a peer entity PE), or by one/ more experts (interchangeably termed as a grading entity GE) or by any combination of both.

[00066] After a buyer (hereinafter termed as a second entity SE) receives the crop, the buyer can further grade the same himself and in case of a variance above a pre -determined threshold in grade as determined by him and that determined by the PE or the GE, use another grading expert (such entities being termed as second grading entity or SGE) for another grading exercise. An SGE can be same as another GE or another PE. The final grading as accepted by the SE can be used to rank various parties such as FE, PE and SGE in the transaction.

[00067] In this manner, proposed invention seeks to distribute the negotiation power equitably between buyers and sellers (farmers). Overtime, a self-sustaining community of sellers of various products (for instance, farmers who wish to sell their crops, as described herein) can be created to grade commodities with a high trust factor. Entities who consistently grade accurately can be incentivized and ranked higher in the proposed system so that they get more and more requests to grade different crops, in turn leading to alternate revenue streams for them.

[00068] Proposed system uses blockchain for various features as elaborated above. Each user/entity of the system can be provided a wallet that can use blockchain unique to the system or public blockchains based on bitcoin, litecoin, ethereum etc., or any other similar as developed. The system can as well use innovations such as artificial intelligence, internet of Things (IoT) etc.

[00069] In an aspect, appropriate user interfaces can be provided to different users/entities of proposed system. Data collected by such interfaces can be stored in an encrypted database and decrypted as and when required. Such data can include, among other data, that relating grading of different crops by different entities as elaborated above.

[00070] Each user /entity can be associated with the blockchain using a unique identification number /unique identity (UID). Various attributes can be used to generate the UID. These attributes can be ( but are not limited to ) place and time of registration of a user with the proposed system, passport, General Service Tax number, value added tax number, unique identification such as Aadhaar as provided by the Indian Government system etc. etc.

[00071] Upon a PE providing feedback (interchangeably termed as FB) on crop grade (indicative of quality) of crop of an FE, such FB can be stored in a table in the database. Further, a copy of the FB can as well be transferred to the blockchain, such FB associated with UID of the FE and the PE. Fikewise, when feedback is provided by a GE, copy of the FB on the blockchain can be associated with the UID of the FE and the GE. When feedback is provided by both the FE and the GE, each FB can be associated with UID of the FE and the PE/GE, as the case may be. Hence, as can be readily appreciated, each FB uniquely identifies the crop graded (through UID of the FE) and the grader (through UID of the PE or the GE or both).

[00072] For logging any information (such as feedback regarding grade of the crop) on to the blockchain, proposed system can generate private keys for all entities involved such as FE, PE, GE and SGE. Further, such private keys (PKs) can remain unchanged for each transaction logged by any entity ( that is, any entity can have one private key) , or can vary dynamically each time a transaction done by the entity ( such as providing feedback) is logged on to the blockchain. The private keys can be generated based upon UID of the users entering into the transaction. [00073] In an exemplary embodiment, each entity (for instance a farmer and other entities as described above) can be provided a blockchain based wallet (cryptocurrency wallet) that can be used by proposed system, such wallet being associated with UID of the corresponding entity.

[00074] The wallet can be used for all cryptocurrency based transactions. For instance, when a PE and/or a GE grades crop of an FE, a pre -determined amount of cryptocurrency can be transferred from the PE/GE as a reference/ payment for services rendered.

[00075] As already described, a Grading Entity (GE) can as well be used to grade a crop. In an exemplary embodiment, if there are no PE present in the proposed system’s database to evaluate a crop, then proposed system can schedule a GE for such evaluation. Such a GE can be selected automatically by proposed system, or manually by an administrator of the proposed system by, for instance, pressing an‘activate GE’ button on his user interface.

[00076] The GE can operate in a similar manner as a PE. The GE can provide feedback (FB) on the quality by grading the crop. The FB can be stored in the database, as well as blockchain and associated with the UID of the FE as well as the GE.

[00077] It can be appreciated that feedback (and hence the grade) of crop as provided by one peer entity can be different from that provide by another peer entity, or another Grading Entity. The second entity can evaluate all these feedbacks to come to its conclusion regarding actual grade of the product. For the purpose the second entity (buyer) can use his past experience with peer entities etc. and can as well use the rankings generated by the proposed system for different entities, as described further. Proposed system can suggest standard grading processes to all the entities in a transaction so that all entities grade a crop based on same parameters. Such processes may require standard evaluation hardware that may be made available to all the evaluating entities by the proposed system / its administrators.

[00078] Transactions through the wallet would require private key (PK) of the entity/user. The PK can be based upon UID of the entity, that can in turn be based upon various attributes of the user/entity such as name, e-mail ID, government provided identification such as passport, GSTN etc. all of which can be stored in an encrypted database of the proposed system using an encryption algorithm that can be used to encrypt the data based on a special sequencing process.

[00079] Transactions using the blockchain can be executed as known in the art. The blockchain may be operatively connected to the proposed system, or be part of it. Unique method of generating private key as elaborated above and associating the same with various transactions can utilize the various advantages of a blockchain viz transparency and accountability. [00080] Proposed system builds in multiple levels of checks and counterchecks. First, a crop of an FE can be graded by a PE or a GE, thereby developing a“Farmers' (or sellers) peer to peer with crop grading experts commodity grading system”. Next, upon a buyer (SE) purchasing such a crop, the buyer himself can in turn grade the crop or use a second grading entity(SGE) for the purpose, thereby developing a “Buyer to farmer (seller) grading and reliability predictive system”. Data generated by both these means can be stored in the private internal encrypted database, or a normal database.

[00081] In this manner, proposed system can enable a complete 360 degree grading of a crop. Other entities (for instance a logistics management company /transporter) can as well be similarly incorporated in the proposed system. Deficiencies/lapses in performance can be pinpointed. For instance, expected time of delivery as well as actual time of delivery from one /more transporters in the supply chain can as well be stored on the blockchain and variances in same easily determined. Transporters can accordingly be graded.

[00082] The blockchain ledger can hold various transactions while proposed system can manage the database relating to various users such as farmers, buyers etc. to enable them to transact using the blockchain. An algorithmic system can connect the blockchain ledger to private and encrypted or normal database of the proposed system. The database can be used to record crop grades from farmers and crop grading experts before sale of crops or commodity as well as to record crop grades from buyers and crop grading experts on the delivered crops or commodities after the sale. All feedback on grades can as well be provided on the blockchain thereby ensuring its reliability and validity.

[00083] In this manner, for every transaction between a seller (FE) and a buyer (SE) a peer farmer (PE) and/or grading expert (GE) can provide feedback (FB) on quality of the product. At option of the buyer, a second grading expert (SGE) can as well be used. Depending upon the crop/product, there can be more than one PE/GE/SGE grading the product/crop. Various feedbacks provided by different entities can be used by the SE to make an appropriate offer for the crop and then buy the same. In an exemplary embodiment, this process of grading through a feedback process can be performed through a industry specific designed web framework.

[00084] The feedback data can be recorded in a private database to be used as and when required. Based upon the feedback value, a pre-determined denomination of cryptocurrency can be exchanged between blockchain based wallets of concerned parties using private keys as generated using the innovative method as elaborated above. The transaction can be on private blockchain as well as on public blockchains. As can be readily appreciated, the cryptocurrency value can be null as well.

[00085] After the crop has been purchased by the buyer (second entity), the SE can as well provide feedback on grade of the crop. A second grading expert can also be used in case of a dispute regarding grading. All such gradings can be to specific guidelines that can be provided to the grading entities. All grades as well as UIDs of the various users/entities can be encrypted and stored in a database as already described.

[00086] In this manner, proposed system can enable any buyer to check grade of a crop the buyer wants to buy in a verifiable manner. The buyer can check the public profile of various sellers as well as graders/peer farmers who have graded the crop using specially designed user interface enabled by the proposed system.

[00087] The grades as well as various profiles can also be verified using blockchain via a cryptocurrency transaction ID provided at user’s profile on a web based user interface system. In this manner, a self-sustaining, reliable and trust based community can be built amongst various users of the proposed system, finally leading to increased satisfaction of all users.

[00088] Further, each entity grading a crop can be automatically ranked by the proposed system based upon variance between grading related feedback provided by the buyer (i.e. final grading as accepted by the buyer/ second entity) after the buyer has physically received the crop and the grading provided by PE, GE or SGE. As can be appreciated, such PEs and/or GEs/SGEs that have lesser variance with the grading provided by the SE can be ranked higher and others can be ranked lower. A customized ranking algorithm can be used by the proposed system for the same. Over time, this can enable graders of high quality to automatically be used more and more often, thereby providing them more and more revenue for their services.

[00089] Likewise, quality of services provided by logistics companies can be similarly graded. Different factors can be built into the system for such evaluation. For instance, attributes of such evaluation can be timely pickup and timely delivery. The FE can rate the logistics company on the first factor, while the SE can grade the logistic company on the second factor. All such grades can be publicly displayed on public profile of the logistic company available at the web interface enabled by the proposed system and available to all users, and connected to blockchain based transactions of corresponding entities, thereby ensuring their reliability.

[00090] Proposed system can gauge reliably the ability of PEs, GEs, SGEs etc. to grade different crops based upon which appropriate rankings can be provided to them that can be used by other users to determine best PE / GE/SGE suited to their purposes. Such rankings can be provided by customized ranking techniques / algorithms. For instance, when grading provided by a buyer (SE) matches grading provided by a PE or a GE, such peer entities or grading experts can be ranked higher. On the other hand, if there is a variation above a pre-determined threshold between a grading provided for instance by a GE (and which may have been used by the SE to finalize his buying decision) and the SE, proposed system can assign a second grading expert (SGE) to grade the crop at destination (that is, address of the buyer/ SE). Grading provided by the SGE can be used to validate those already provided by other entities. It can be appreciated that such rankings will encourage each entity to provide as accurate grade of a crop the entity is grading as is within his experience. Over time, as more and more transactions happen, more expert graders will automatically be ranked higher than others. Hence, the proposed system continuously improves itself as it is used.

[00091] As each transaction is completed, profiles of all entities involved in the transaction can get updated using, for instance, an Internet based application such as a web application, operatively connected to the proposed system. Such profiles can include, for instance, various transactions so far handled by them, their ranks in giving reliable grading (as elaborated above), location etc. Even buyers can as well be validated, / graded by other stakeholders (a seller can for example grade a buyer on promptness of the buyer in paying). This can help entities in the future to transact with one another appropriately based upon reliable data. Such transactions can also be recorded in the database as well as onto the blockchain and lead to updation of profiles in the web interface interactive platform. In this manner, proposed system uses machine intelligence to continuously improve itself automatically. Recording transactions using a blockchain ledger invokes blockchain features in innovation disclosed herein.

[00092] FIG. 1 illustrates overall architecture of the proposed system, in accordance with an exemplary embodiment of the present disclosure.

[00093] As illustrated, proposed system 102 can be operatively connected to a blockchain (BC) 104 for recording various transactions. Further, different entities (users) registered with system 102 can interact with it using their computing devices as shown. Necessary user interfaces can be provided on the computing devices. System 102 can be, for instance, configured at a server/ cloud and be operatively connected via an appropriate application to different computing devices of different entities / users. Further, various transactions such as feedback of different entities can be recorded in BC104. [00094] In an exemplary embodiment, each entity can as well be associated with a cryptocurrency based wallet (interchangeably termed as wallet or cryptocurrency wallet herein) and cryptocurrency transactions recorded using UID and private key (PK) of different entities as elaborated above.

[00095] In an aspect, a First Entity (FE) shown as FE (that can be seller of a crop) can send, using his computing device shown as CD1, a First Request (FR) to the proposed system. The FR may trigger the requests for recipients to grade the crop that the FE is planning to sell at an e- commerce portal associated with the proposed system, further may provide grade claimed by the FE. Using device CD1, the FE can select peer entities (PEs) or grading entities (GEs) or any combination of these to which the FR may be forwarded based on suitability of type of crops. Or the proposed system may automatically select these entities based upon factors such as location (that can be part of the FR), rank of a PE, and rank of a GE etc.

[00096] In another aspect, the system can record the FR on BC 104 for further use. Further, the proposed system 102 can send the FR to various PEs or GEs. As shown in FIG. 1, the FR can be sent to computing device CDPE1 associated with PEI and to computing device CDGE1 associated with grading entity 1.

[00097] In an exemplary embodiment, it may not be necessary that the FE sends an FR and grading could be done irrespective of FR details. For instance, a FE (say a farmer) could put details of a crop on sale when feedback requests to one/more pre-selected grading entities (GEs) would be triggered and the process proceed further. Any other embodiment/exemplary implementation that allows the crop to be graded by GEs or Peer Entities are well within the scope of the present invention.

[00098] In yet another aspect, the entities receiving FRs can revert with their feedback that can include, among other data, data regarding at least the grade of the crop as evaluated by them. For instance, entity PEI can send feedback FBI using his computing device CDPE1. Fikewise GE1 can send FB2 using his computing device CDGE1. Various feedbacks such as FB I, FB2 etc. can be recorded on BC104, and can include at least grade as determined by corresponding evaluating entities. For such evaluation, the evaluating entities can visit the FE and check quality of the crop. Such evaluation can be based upon standard grading processes suggested by the proposed system, as already elaborated.

[00099] In an aspect, a second entity SE (for instance, a buyer desirous of purchasing crop of the first entity which has been graded by PEI and GE1) can retrieve various feedbacks (FB I and FB2) from proposed system 102, further verified using BC104, using his computing device CD2 as illustrated. Accordingly the SE can negotiate with the FE regarding purchase of the crop.

[000100] In case the SE proceeds with purchase of the crop, the second entity may find a variance between grade(s) based upon which he made the procurement decision and the actual grade of the crop when received by him. In case he wishes to, the SE can, using device CD2, issue a second request shown as SR that can ask for grading of the crop be done again (for instance, this time at the buyer’s location) using a second grading entity shown as SGE1. Entity SGE1 can be automatically allocated by the proposed system or the SE can selected the SGE from a plurality of GEs (that may/may not be same as GEs that received the FR), and likewise from different PEs. The SR can as well be stored at BC 104. Further, SGE1 can receive the SR on his computing device shown as CDSGE1 and provide a feedback shown as FB3 to proposed system 102. Proposed system 102 can log FB3 onto BC104 (so that its veracity for all time is assured) from where the SE can retrieve the same using CD2. FB3 can include, among other data, data regarding at least the grade of the crop as evaluated by SGE1. It can readily be understood that the second entity can as well select more than one second grading entities. A blockchain transaction can be performed to log/ register feedback FB3 into blockchain BC104. Further, the SE can crosscheck feedback FB3 from CD2 and then verify it again using BC104 to be certain of its validity.

[000101] Variance between grade finally accepted by the SE and those determined by second grading entities, peer entities and grading entities can be used to evaluate and rank the expertise of different entities such as FEs, PEs, GEs, SEs, and SGEs in grading different crops on a continuous, real-time basis. Such ranks can be enabled on public profiles of different entities so as to assist any second entity in getting accurate grade of a crop.

[000102] Upon PEI providing feedback (FBI) on crop grade (indicative of quality) of crop of FE, FBI can be stored in a table in a database. Further, a copy of FBI can as well be transferred to the blockchain BC104, FB I associated with UID of the FE and PEI. Likewise, when feedback FB2 is provided by GE1, copy of the FB2 on the blockchain BC104 can be associated with the UID of the FE and GE1. When feedback is provided by both FE1 and GE1, each FB can be associated with UID of the FE and PE1/GE1, as the case may be. Hence, as can be readily appreciated, each FB uniquely identifies the crop graded (through UID of the FE) and the grader (through UID of the PEI or the GE1 or both), and is logged onto block chain BC104. [000103] As already elaborated, for logging any information (such as feedback regarding grade of the crop) on to the blockchain, proposed system can generate private keys for all entities involved such as FE, PEI, GE1 and SGE1.

[000104] FIG. 2 illustrates a block diagram of the proposed system in accordance with an exemplary embodiment of the present disclosure.

[000105] As illustrated, proposed system 102 can have (or be operatively connected to) various databases (or one database can maintain all information). As illustrated, database 202 can record crop grades from farmers, database 204 can record crop grades from crop grading experts while database 206 can record crop grades from buyers. All such databases can connect via a connector unit 208 to public or private blockchain servers to store and make available all transactions as required. For instance, blockchain ledger 212 can record various transactions pertaining to a farmer (first entity) and further validate the farmer based on feedback of other stakeholders (for instance buyer ( second entity) and peer entities), blockchain ledger 214 can record various transactions pertaining to a grading expert and further validate the grading expert based on feedback of other stakeholders (for instance buyers (second entities) and peer entities), and blockchain ledger 216 can record various transactions pertaining to a buyer (second entity) and further validate the buyer based on feedback of other stakeholders ( for instance a farmer ( first entity) and a grading expert).

[000106] Connector unit 208 can as well provide all relevant information to a grading and reliability prediction unit shown as 210. Unit 210 can use all such information being generated to evaluate entities as to their ability to reliably grade different crops. Based upon such evaluation different entities can be ranked by unit 210 and such ranks can be displayed on their public profiles as already described.

[000107] It would be appreciated that units as described above are only exemplary units and any other unit or sub-unit can be included as part of the proposed system. These units too can be merged or divided into super-units or sub-units as may be configured and can be spread across one or more computing devices operatively connected to each other using appropriate communication technologies.

[000108] Further, although the proposed system has been elaborated as above to include all the main units, it is completely possible that actual implementations may include only a part of the proposed units or a combination of those or a division of those into sub-units in various combinations across multiple devices that can be operatively coupled with each other, including in the cloud. The units can be configured in any sequence to achieve objectives elaborated. Also, it can be appreciated that proposed system can be configured in a computing device or across a plurality of computing devices operatively connected with each other, wherein the computing devices can be any of a computer, a laptop, a smart phone, an Internet enabled mobile device and the like. Therefore, all possible modifications, implementations and embodiments of where and how the proposed system is configured are well within the scope of the present invention.

[000109] In an aspect, the proposed system can be operatively connected using an Internet based application such as a web application to any Internet enabled computing device, and can as well have a mobile application that can be downloaded on a mobile device that can connect to Internet for such connection. In such manner, the proposed system can be available 24*7 to its users (different entities as elaborated above). Any other manner of implementation of the proposed system or a part thereof is well within the scope of the present disclosure/invention. The computing device can be a PC, a tablet, a smart phone and other like devices.

[000110] FIG. 3 illustrates various interactions amongst different entities that can be enabled by the proposed system in accordance with an exemplary embodiment of the present disclosure.

[000111] In an exemplary embodiment, a first entity (FE) can be a farmer 302 desiring to have his crop graded in order to sell it. He can request different peer entities (PEs) (nearby farmers, for instance) shown as 304, 306 and 308 to grade his crop. He can as well request grading entities (GEs) shown as 310 and 312 to as well grade his crop. Thereafter different second entities (SEs) shown as 314 and 316 (that maybe interested buyers, for instance) can see (retrieve) the grades provided and accordingly interact with the first entity 302. The proposed system can as well automatically allocate different PEs or GEs to handle the request of the FE based on location, ranking and availability of the PEs or GEs.

[000112] All interactions amongst different entities and grades determined etc. can be recorded into a private /encrypted database and thereafter into a blockchain ledger using private keys associated with each entity. The usage of blockchain ensures reliability and trust on different transactions, including grades provided by different entities to the crop, as described above.

[000113] FIG. 4 illustrates an exemplary method of implementing proposed system in accordance with an exemplary embodiment of the present disclosure.

[000114] In an aspect, the method elaborated herein can be described in general context of computer executable instructions. Generally, computer executable instructions can include routines, programs, objects, components, data stmctures, procedures, modules, functions, etc., that perform particular functions or implement particular abstract data types. The method can also be practiced in a distributed computing environment where functions are performed by remote processing devices that are linked through a communications network. In a distributed computing environment, computer executable instructions may be located in both local and remote computer storage media, including memory storage devices.

[000115] The order in which the method is described is not intended to be construed as a limitation, and any number of the described method blocks can be combined in any order to implement the method or alternate methods. Additionally, individual blocks may be deleted from the method without departing from the spirit and scope of the subject matter described herein. Furthermore, the method can be implemented in any suitable hardware, software, firmware, or combination thereof. However, for ease of explanation, in the embodiments described below, the method may be considered to be implemented in the above described system.

[000116] In an aspect, present disclosure elaborates upon a method for determining grade of a product. The method can include, at step 402, receiving, at a computing device, from a first entity (FE), a first request (FR) comprising grade of the product as claimed by the FE; and at step 404, storing, at the computing device, the FR in a first database (DB).

[000117] The method can further include, at step 406, processing, at the computing device, the FR to select any or both of at least one peer entity (PE) and at least one grading entity (GE); and at step 408, receiving, at the computing device, a first feedback from selected PE and a second feedback from selected GE, each of the first and the second feedbacks being stored in a second DB and indicative at least of actual grade of the product.

[000118] The method can further include, at step 410, generating, at the computing device, a private key (PK) for each of the selected PE , the selected GE, and the FE; and at step 412 logging onto a blockchain at least a part of the FR and any or a combination of at least a part of the first feedback and at least a part of the second feedback using corresponding private keys, the part logged of the first feedback indicative at least of actual grade of the product as determined by the selected PE and the part logged of the second feedback indicative at least of actual grade of the product as determined by the selected GE.

[000119] FIGs. 5A to 5C illustrate exemplary views of the computing device used by at least one Peer Entity (PE) and/or by the at least one Grading Entity (GE) to undertake the grading process. [000120] In an aspect, the proposed hardware device has a display screen with camera attached to it with IOT (Internet of Things) sensing GSM device with warehouse and billing management paper rolling devices used as part of standard grading process of agriculture commodities. The camera can be used to take picture of the crop. Further the image undergoes processing for the first level of grading. IOT sensing device is used to get the supporting data for second level of grading. Further, the warehousing and billing paper rollers are used to benchmark the crop as the final part of the grading system of agriculture commodities. Each of the computer device with Primary entity (first user), Secondary entities including grading entities/users can possess this device to collect the images, environmental data of the farm, and include standard warehousing and billing management for technologies for the harvested crop to finalize the grade of the harvested crop.

[000121] In an exemplary aspect, the two paper rolling devices can be used for sticker generation to manage warehouse bags, and/or to generate bills after sales.

[000122] As used herein, and unless the context dictates otherwise, the term“coupled to” is intended to include both direct coupling (in which two elements that are coupled to each other or in contact with each other) and indirect coupling (in which at least one additional element is located between the two elements). Therefore, the terms“coupled to” and“coupled with” are used synonymously. Within the context of this document terms“coupled to” and“coupled with” are also used euphemistically to mean“communicatively coupled with” over a network, where two or more devices are able to exchange data with each other over the network, possibly via one or more intermediary device.

[000123] Moreover, in interpreting both the specification and the claims, all terms should be interpreted in the broadest possible manner consistent with the context. In particular, the terms “comprises” and“comprising” should be interpreted as referring to elements, components, or steps in a non-exclusive manner, indicating that the referenced elements, components, or steps may be present, or utilized, or combined with other elements, components, or steps that are not expressly referenced. Where the specification claims refers to at least one of something selected from the group consisting of A, B, C ... .and N, the text should be interpreted as requiring only one element from the group, not A plus N, or B plus N, etc.

[000124] While the invention has been described using primarily male gender for different entities, it can readily be appreciated that is solely for ease in elaboration and proposed system can be used by anyone irrespective of gender. Further, in a preferred embodiment proposed system may be enabled using Internet. However, it can be readily understood that other communication methods such as those where the system is configured at a server and various computing devices connect to it using LAN, WAN etc. may as well be deployed.

[000125] While some embodiments of the present disclosure have been illustrated and described, those are completely exemplary in nature. The disclosure is not limited to the embodiments as elaborated herein only and it would be apparent to those skilled in the art that numerous modifications besides those already described are possible without departing from the inventive concepts herein. For instance, the system as disclosed can as well be used for grading different services as provided by different service providers such as transporters etc. All such modifications, changes, variations, substitutions, and equivalents are completely within the scope of the present disclosure. The inventive subject matter, therefore, is not to be restricted except in the spirit of the appended claims.
