Background

In recent years, the take-out industry has been developing and the take-out has become a more value-added service. Meanwhile, the counterfeiting phenomena such as taking-out brushing, single brushing and scoring are also endless. Some bad merchants falsely promote shop public praise by brushing bills, brushing comments and the like, so that certain harm is brought to the mind and body of consumers, and meanwhile, huge loss is caused to other regular catering shops. The existing takeout scoring method has no accurate reference value due to the phenomena of data tampering of shops at the background, deletion of negative evaluation and feedback information of consumers, manual bill swiping and the like. Although the supervision department actively develops a policy, increases the supervision and requires that the sales scoring information displayed by the take-out shops is real and accurate, the phenomenon of brushing the order and scoring in the take-out markets still exists in the presence of high benefits, and the appearance of a new anti-brushing mode is particularly urgent.

The block chain technology has the excellent characteristics of multiple centers, non-tampering, collective maintenance and the like, and has very wide application prospects. It can be understood as an account book of the present disclosure, each node on the network keeps a copy of the bill, and a single node cannot tamper with historical transactions, so that the reliability and the safety of data are ensured.

The block chain is a new technology combined with the hot problem of taking out anti-billing. The problem of the current on-line shopping and taking-out bill brushing scoring is solved by utilizing the natural advantages of the block chain in the aspects of recording, storing, tracking data and the like. The block chain technology has a plurality of application achievements in other aspects, and the anti-brush scoring can be realized by the technology, so that consumers can find real good takeaway more quickly and accurately.

The reliability of each link in the takeaway manufacturing and conveying process is ensured by using the decentralized feature of the block chain; by utilizing the technical advantages, the problem that the data reliability of the intermediate link is high due to excessive participation of human factors in the whole supply chain is solved. The block chain is essentially a public account book, has the characteristics of openness and transparency, and can effectively solve the problem that the traditional scoring information is not transparent. Because all people who participate in the data on the chain take charge of the data, the counterfeiting cost is greatly increased, and the phenomenon of current flooding by swiping the single can be effectively improved. The block chain technology is used for recording links of takeout production and transportation, so that time delay, cost and manual errors are reduced, the real takeout score automatically calculated by the algorithm can be obtained, the reliability and safety of data are ensured, and a new method for preventing takeout from being swiped is created.

Detailed Description

The present invention is described in further detail below with reference to the attached drawing figures.

The main supervision departments in the content of the invention are food and drug supervision and management departments in various regions, and the supervision departments are not only responsible for supervising the purchasing condition of the upstream food materials of the shops, but also responsible for examining and recording the participating units of the overseas supply chain. And before the takeaway sale, according to the audit condition of the relevant department, the corresponding anti-counterfeiting mark is issued to the takeaway type which can be listed by the audit shop, and the correspondence is ensured.

The shops meeting the takeaway production standard need to pass the audit, and the audit process comprises the following steps: applying for food operation license from local related departments, auditing the qualification of the shops by the related departments, and recording the selling type of the shops by a local supervision platform.

The supervision department uploads the list of the checked shop units to the method platform, and the method platform passes the registered and authorized units according to the list provided by the supervision department and sends user names and passwords for logging in and uploading information. The identity is confirmed by the representative of the unit, and the name of the shop, the responsible person, the telephone and other information are filled in. The information is stored in a platform database, and is convenient for merchants, riders, consumers and supervision departments to consult.

Fig. 1 is a flow chart of the present invention, which mainly includes three parts, in a block chain of a platform of a takeaway initial information entry method of the first part, a label sheet generating a unique ID is attached to a takeaway packaging box, and the present invention includes the following steps:

(1) and the units meeting the conditions carry the related materials to a supervision department for auditing and registering, so that the credibility and non-repudiation of the members in the block chain are guaranteed. The units and the responsible persons participating in each link of local takeout distribution, the units meeting the conditions, including the shop platform and the takeout rider, carry related materials to the supervision department for application and preparation, the units meeting the condition requirements are approved and passed, and the supervision department registers the participating units passing the approval and marks the participating units as authorized, so that the credibility and the non-repudiation of the members in the authorized units and the block chain are ensured. The method platform will distribute and record the role and authority of the unit according to the list provided by the supervision department.

(2) The authorized units are registered on the method platform, and the method platform determines whether the units pass the examination according to the list provided by the supervision department. And (4) registering the successful unit, and uploading the information including the user name, the password, the company name, the representative role, the responsible person, the telephone and the authority to a database of the method platform by the method platform for storage. If a newly added unit can apply in the supervision department in the midway, the method platform allocates account number and password, corresponding roles and authorities for the new unit according to the list information provided by the supervision department;

(14) the shop reports the type, the quantity, the material drawing and the like of the takeout to the supervision department, data are backed up to the block chain of the method platform in real time in the period, and the shop logs in and uploads the takeout commodity information to the block chain through the method platform.

(15) After the shop begins to operate, the supervision department performs random inspection on the shop, including quality detection, whether the platform score is refreshed or not, and the shop should report the operating condition to the supervision department periodically and actively.

(16) For each takeout, the shop should upload corresponding takeout data, the supervision department gives a unique ID to the takeout data, and meanwhile basic information of the takeout corresponding to the ID is uploaded to a block chain of the platform of the method. The supervision department issues a two-dimensional code corresponding to the anti-counterfeiting mark and containing an RFID mark, the mark contains the unique mark of the takeout, and the two-dimensional code is attached to a take-out packaging box to inquire the mark, so that the reuse is prevented. The correspondence between the character string and the ID should also be stored. The association will issue a certain number of ID tags in advance according to the business scale of the past shops. For the ID identification which cannot be used up in the time limit, the ID identification is returned or reported by the merchant to the supervision department after the time limit is over, and the ID identification should not be reserved privately. For those in-term ID tags that are exhausted in advance, the store may additionally apply to the regulatory body.

The second part is the generation and recording of take-out transportation sales information, and the specific method is as follows:

(1) after the take-out rider gets the take-out from the shop, the take-out rider finishes the hand-over procedure with the shop code scanning of the production take-out, and after the hand-over procedure is finished, the rider uploads information to the method platform. The store delivers the take-away items for transport by the rider. In the process of handing over the rider with the shop, whether the variety and the number of the takeout are correct, whether the package is damaged, whether the block chain ID is complete and the like are checked, and the rider can handle the handing over procedure with the shop. After the two parties confirm that the information is correct, the rider scans the ID on the takeout and inputs the information through the method platform, wherein the information comprises the takeout ID, the takeout type quantity, whether the information is damaged or not, rider information and a timestamp, and the information is uploaded to a block chain of the method platform. In order to reduce the time for the rider to fill in information, for each piece of recorded information, there will be a default value in the block chain, and the rider only needs to check and modify the status bar that is different from the default value. To ensure the authenticity of the data source and the authenticity of the data itself, the information must be scanned for the identification ID into the compilation.

(2) And after the consumer receives the takeout through the rider, the consumer uploads the selling information through the client to complete the transaction. The takeaway rider provides home service or places the takeaway rider in a designated place, and a consumer inquires information such as a timestamp from generation to transportation of the takeaway by scanning ID identification on the takeaway, fills in the current takeaway state including the takeaway ID, the type number, whether packaging is damaged or not and customer names (optional) and uploads the information to a block chain. The take-out information needs to be filled in by scanning codes and cannot be manually input. After the meal is finished, the consumer scans the codes again, submits scores and issues comments, and uploads the information to the block chain after confirming that the information is correct, so that the transaction is finished.

The third part is takeaway information inquiry, consumer logs in the website provided by the platform, and inputs takeaway identification or character string corresponding to shop identification. And inquiring the real sales volume and the score of the takeout through a method platform algorithm.

Fig. 2 is a flowchart of takeout unique ID generation and basic information initialization processing. The qualified shops and takeaway riders are checked and registered in the industry association to obtain authorization. The method platform can confirm whether the user is an authorized user according to the audit list provided by the relevant department. If yes, continuing, otherwise, failing to register.

After successful registration, the custody department uploads information (user name, password, shop name, representative role, responsible person, phone, authority, etc.) to the database of the method platform. And the shops upload the takeout making information to the block chain through the method platform. And (3) registering and coding the takeout food materials, the time for starting production and the like, and backing up all registered information to a block chain of the method platform in real time during the period for consumers and supervision departments to inquire. The whole process from manufacturing to conveying is recorded on a method platform in real time, and a platform algorithm automatically detects the order-brushing operation and automatically judges whether the order-brushing behavior exists or not. And the supervision department randomly checks the purchasing conditions of shops and upstream food materials. And uploading data to the block chain by the shop login method platform. The supervision department generates a unique label, production time and a unique character string for delivering takeoffs, and the unique label, the production time and the unique character string are used for inquiring the label to prevent multiplexing. The identification ID is a disposable and non-reusable two-dimensional code, and the takeout and the identification ID are ensured to be in one-to-one correspondence.

Fig. 3 is a flow diagram of a take-away transportation sales information recording and query process. After receiving the takeout, the takeout rider checks the condition of each takeout one by one, records whether the takeout package is damaged or not, the quantity, the order receiving time and the like, and transacts the handover procedure with the shop. After the two parties confirm that the information is correct, the rider scans the takeout RFID, reads the takeout ID, and inputs the takeout ID including whether the takeout ID is damaged, the quantity, the time and the timestamp through the client. The takeaway ID needs to be read in through a two-dimensional code on the takeaway so as to ensure authenticity. After completion, the rider uploads information to the block chain of the method platform. The consumer accepts the take-out. The service of the rider is divided into two types of service of home delivery and self-taking in place. The customer can obtain the input information including the takeout ID, the production time, the quantity, whether the product is damaged or not, the timestamp, the customer name (optional) and the like from the code scanning login method platform and upload the input information to the block chain of the method platform. Wherein the takeaway ID must be verified by code scanning. After the transaction is completed, the transaction record will be updated to completion on the method platform. The recorded data is refined to each takeout of the shop, the responsible person of each node and the recorded data is extremely rich and complete. The block chain technology is applied to the outsourcing supply chain, so that the recording is more reliable, and the supervision is more transparent.

Fig. 4 is a takeaway information query flow diagram. The consumer logs on the method platform of the invention, inputs the character string of the takeout goods or the corresponding shop identification, and inquires the past transaction record of the shop. The authenticity of the shop score and the sales volume is automatically calculated by a platform detection algorithm, and the data are corrected when the suspicious single-brush score phenomenon exists. And an alarm is given when a large number of the brushing lists and scores exist, and the supervision department can further verify the responsibility.

The above description is only a partial embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and equivalents can be made without departing from the principle of the present invention, and those modifications and equivalents which are made to the claims of the present invention fall within the protection scope of the present invention.
