[0040] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0041] The bill detection method provided in this application can be applied to Figure 1In the application environment shown. Among them, the terminal 102 communicates with the server 104 through the network. The terminal 102 obtains the graphic code of the bill to be detected through the network, extracts the inspection elements in the graphic code; obtains the inspection elements entered in the preset page, and submits the input inspection elements; receives the inspection result in response to the inspection element, and the inspection result can be used to characterize the authenticity of the bill to be detected; outputs the inspection result. Among them, the terminal 102 can be but not limited to various personal computers, laptops, smart phones, tablet computers and portable wearable devices, and the server 104 can be implemented by an independent server or a server cluster composed of multiple servers.

[0042] In one embodiment, Figure 2 As shown, a bill detection method is provided, which is applied to Figure 1 The terminal 102 in the example is used as an example to illustrate, and the following steps are included:

[0043] Step 202, obtaining the graphic code of the bill to be inspected, and extracting the inspection elements in the graphic code.

[0044] Among them, the bill is a certificate of relevant information such as the transfer of resources or assets that occurs during the exchange of goods or transactions. The type of bill to be tested can be an electronic bill or a paper bill, and the type of bill to be tested is not limited here. The face of the bill to be tested includes data such as a graphic code, detailed information of the two parties to the resource or asset transfer, the number of resources or assets transferred, the transfer time, the bill code, the bill number, and the bill password.

[0045] A graphic code is a graphic that can be used to record data and is generated according to specific rules. The graphic code can be a QR code or a barcode, which is not limited here. For example, when the graphic code is a QR code, the QR code is generated according to preset QR code rules. The QR code rules may include the domain name of the web page for checking the bill to be tested and the hash value of the bill to be tested, where the domain name is the name of a computer or computer group on the Internet composed of a string of characters or letters separated by dots, such as www.wikipedia.org; the hash value is a hash function that shuffles and mixes the data to recreate a fingerprint called a hash value (hash values, hash codes, hash sums, hashes). The hash value is usually represented by a short string of random letters and numbers. Commonly used hash algorithms include MD5 and SHA-1.

[0046] Verification factors are data that can be used to verify the authenticity of bills. Verification factors include the bill code and bill number of the bill to be tested. Verification factors can also include bill type, seller name, buyer name, invoice date, total price and tax, check code, and bill status.

[0047] Specifically, after obtaining the bill to be inspected, the built-in scanner of terminal 102 is triggered to scan the graphic code of the bill to be inspected after receiving the scanning instruction. After the scanner identifies the graphic code of the bill to be inspected, the parser parses the graphic code to obtain the parsing result, and the inspection elements of the graphic code are extracted from the parsing result. Alternatively, the terminal 102 may be triggered to scan the graphic code of the bill to be inspected after receiving the scanning instruction. After the graphic code scanning device identifies the graphic code of the bill to be inspected, the graphic code is parsed by the graphic code parsing model to obtain the parsing result of the graphic code, and the inspection elements of the graphic code are extracted from the parsing result.

[0048] Step 204, adding the extracted verification elements to the preset page.

[0049] The preset page is a page pre-designated for checking the bill to be tested.

[0050] Step 206, obtain the verification elements added in the preset page, and submit the added verification elements.

[0051] Specifically, according to the input requirements of the preset page, the inspection elements that meet the conditions are obtained from the extracted inspection elements. After obtaining the inspection elements that meet the conditions, the submission of the input inspection elements is triggered, and the input inspection elements are processed.

[0052] Step 208, receiving the verification result in response to the submitted verification factor, and the verification result is used to characterize the authenticity of the bill to be tested.

[0053] Step 210, output the inspection result.

[0054] Specifically, the output inspection result can be a result that directly represents the authenticity of the bill to be tested, for example, the inspection result obtained is "the bill to be tested is true" or "the bill to be tested is false". The output inspection result can also be used to compare with the bill information on the bill to be tested to determine the authenticity of the bill to be tested; the authenticity of the bill can be detected by manually checking the inspection result and the bill information on the face of the bill to be tested, or by pre-training a model based on a sample bill to be tested to obtain a trained bill detection model, inputting the inspection result of the inspection element response into the trained bill detection model, and performing detection through the bill model and the bill information on the face of the bill to be tested, and outputting the detection result. The bill inspection method is not limited here.

[0055] The verification result includes the bill code, bill number, and bill password area. The hash values ​​in the bill code, bill number, and bill password area are input into the bill detection model. When the bill detection model detects that the verification result is exactly the same as the bill information on the bill to be detected, the bill detection model outputs a prompt "The bill to be detected is true"; when the bill detection model detects that any one of the hash values ​​in the bill code, bill number, and bill password area is different from the bill information on the bill to be detected, the bill detection model outputs a prompt "The bill to be detected is false".

[0056] Optionally, the inspection result may also include the bill type, the name of the seller, the name of the buyer, the invoice date, the total price and tax, the check code, the bill status, etc. All the inspection results are input into the bill detection model. When the bill detection model detects that the bill code, bill number, bill password area, bill type, name of the seller, name of the buyer, the invoice date, the total price and tax, the check code, and the bill status are exactly the same as the bill information on the bill to be detected, the bill detection model outputs a prompt "the bill to be detected is true". When the bill detection model detects that any one of the bill code, bill number, bill password area, bill type, name of the seller, name of the buyer, the invoice date, the total price and tax, the check code, and the bill status is different from the bill information on the bill to be detected, the bill detection model outputs a prompt "the bill to be detected is false". Among them, the check code is generated by the random function Rand(), and the check code can be a random combination of at least 5 digits plus letters. The check code of the inspection result output by each bill to be detected is different; the bill password area corresponds to the bill hash value of the bill to be detected.

[0057] In the above-mentioned bill detection method, by obtaining the graphic code of the bill to be detected, extracting the inspection elements in the graphic code, adding the extracted inspection elements to the preset page, obtaining the inspection elements added in the preset page, submitting the added inspection elements, receiving the inspection results in response to the submitted inspection elements, the inspection results are used to characterize the authenticity of the bill to be detected, and outputting the inspection results; the preset page is a page that can detect the authenticity of the bill, the inspection elements obtained are the inspection elements to be entered on the preset page, and are not the inspection elements of the general page, and the preset page is automatically switched to submit the input inspection elements. The accepted inspection results can not only obtain relevant information of the bill to be detected, but also determine the authenticity of the bill to be detected.

[0058] In one embodiment, the bill hash value is generated when it is sent to the receiving address corresponding to the bill to be detected, and the bill hash value is obtained by processing the bill information corresponding to the bill to be detected through a hash algorithm.

[0059] The bill information includes the bill type, bill code, bill number, seller name, buyer name, invoice date, price and tax total, verification code, invoice status, etc. of the bill to be tested.

[0060] The hash algorithm is a function constructed based on the hash function. The hash algorithm can transform input of any length into an output of fixed length through the hash algorithm to obtain a hash value. The hash algorithm includes the Secure Hash Algorithm (SHA256) and the encryption algorithm RIPEMD160.

[0061] The receiving address is usually a string of numbers selected randomly. The string of numbers is encrypted with SHA256 as the private key, and then a public key is generated through the Elliptic Curves Cryptography (ECC). The public key is processed by the SHA256 algorithm and the RIPEMD160 algorithm to obtain the corresponding public key hash. The public key hash and the address version number and checksum corresponding to the public key hash are generated through BASE58 encoding. Among them, the process of obtaining the public key from the private key through the ECC algorithm is irreversible.

[0062] Specifically, when the bill to be tested is sent to the corresponding receiving address, the bill information corresponding to the bill to be tested is processed by the hash algorithm to obtain the bill hash value. The bill hash value is generated based on the determined bill information and cannot be changed. The bill to be tested can correspond to at least one hash value, and a new hash value will be generated every time the bill to be tested circulates. For example, when the bill asset to be tested is generated, the asset generation time, the corresponding participants and other data are processed by the hash algorithm to obtain the hash value corresponding to the asset; when the bill to be tested is sent to the corresponding receiving address, the bill hash value is obtained based on the bill information.

[0063] In one embodiment, obtaining the graphic code of the bill to be inspected and extracting the inspection elements in the graphic code include:

[0064] Obtain the graphic code of the bill to be tested, extract the link of the graphic code, which includes the bill hash value; according to the bill hash value, obtain the inspection element corresponding to the bill hash value from the corresponding database.

[0065] A link refers to a connection relationship from an object to a target object. The object can be a word, a picture, or information, etc.

[0066] Specifically, when the bill to be tested is generated, the inspection elements related to the bill to be tested are stored in the database, and the inspection elements are associated with the bill hash value through mapping, that is, when the bill hash value in the graphic code link is extracted, the inspection element corresponding to the bill hash value is found from the database through the mapping relationship. The inspection elements are stored in the database and will not be changed or lost, ensuring the accuracy and integrity of the data. The link may also include the bill assets and bill numbers of the bill to be tested. The bill assets and bill numbers of the bill to be tested can be directly obtained by extracting the link of the graphic code, and the inspection elements corresponding to the bill assets and bill numbers can be obtained from the database according to the bill assets and bill numbers, which increases the way to obtain the inspection elements and improves the accuracy of the inspection elements.

[0067] In one embodiment, the bill to be detected is a blockchain bill.

[0068] Among them, blockchain is a chain data structure that combines data blocks in a sequential manner in chronological order. Blockchain technology is a new distributed infrastructure that uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses smart contracts composed of automated script codes to program and operate data. The life cycle of bills can be recorded on the blockchain, that is, each flow of bills is recorded in chronological order through timestamps, and bills can be queried through query instructions.

[0069] Blockchain bills are proof of consumption or payment that is completely generated by algorithms. Blockchain bills allow users to apply for, generate, check, and enter bills on the blockchain, saving the bill generation and reimbursement process; users can also store, circulate, and reimburse bills on the blockchain. When users operate bills on the blockchain, a corresponding operation identifier will be generated and stored in the database corresponding to the blockchain. For example, when a reimbursement instruction corresponding to a blockchain bill is received, a reimbursement identifier corresponding to the reimbursement instruction will be generated. When the reimbursement instruction of the blockchain is received again, the corresponding reimbursement identifier is detected, and a "reimbursed" prompt is output to avoid multiple reimbursement of blockchain bills; the integrity of blockchain bill information and data cannot be changed, ensuring the authenticity of the bill.

[0070] Specifically, blockchain bills are obtained through blockchain technology, a scanning instruction is received on the display page of the blockchain bill, the terminal scanner is triggered to scan the QR code of the blockchain bill, the link in the QR code is extracted, the inspection element corresponding to the bill hash value is obtained from the corresponding database according to the bill hash value in the link, the inspection domain name in the QR code link is obtained, the preset page corresponding to the inspection domain name is switched to, the extracted inspection element is added to the preset page, the inspection element added in the preset page is obtained, and the added inspection element is submitted, and the inspection result in response to the submitted inspection element is received, and the inspection result is used to characterize the authenticity of the bill to be tested, and the inspection result is output. On the blockchain, any participant of the blockchain bill can query the specific data of each flow of the blockchain bill in the database corresponding to the blockchain, which can realize the historical tracing of the blockchain bill, and can also realize the application, generation, inspection, accounting, storage, circulation and reimbursement of the blockchain bill.

[0071] In one embodiment, Figure 3 As shown, the method further includes: switching to the ticket description page of the ticket to be tested, and playing the media information corresponding to the tested ticket, which specifically includes the following steps:

[0072] Step 302: Display the inspection result on the display interface corresponding to the preset page, and the inspection result includes the link address of the bill description of the bill to be inspected.

[0073] The link address includes web addresses of various network resources of different formats, different attributes, and different locations, and jump addresses of local resources. The different formats include electronic documents, pictures, multimedia audio, etc., and the different locations include local resources, network resources, etc. The bill description link address is the web address of the bill description. For example, the link address can be the web address of a web page on the Internet, the web address of a network service, and the network service can be a weather service, message push, etc.; it can also be the jump address of a local file or a local picture.

[0074] Step 304: Obtain a first trigger instruction of a bill description link address from the display interface, and switch to a bill description page of the bill to be detected corresponding to the first trigger instruction.

[0075] Among them, the trigger instruction is used to execute the program processing condition instruction, and the first trigger instruction is used to trigger the switch to the bill description page of the bill to be detected. The first trigger instruction can be triggered by a timer. When the preset time is reached, the display interface is switched to the bill description page of the bill to be detected corresponding to the first trigger instruction, or the bill description page of the bill to be detected corresponding to the first trigger instruction is popped up on the display interface; the first trigger instruction can also be generated by a voice recognition module. For example, when the inspection result is displayed on the display interface, a voice trigger instruction of the bill description link address is received, and the voice trigger instruction is converted into a first trigger instruction through the voice recognition module. After responding to the first trigger instruction, the description page of the bill to be detected corresponding to the first trigger instruction is switched to the description page of the bill to be detected corresponding to the first trigger instruction, or the bill description page of the bill to be detected corresponding to the first trigger instruction is popped up on the display interface. Here, the triggering method of the first trigger instruction is not limited. Specifically, after obtaining the first trigger instruction of the bill description link address from the display interface, the first trigger instruction is responded to, and the bill description page of the bill to be detected corresponding to the first trigger instruction is switched or popped up. The description page includes a description of the bill to be tested, the characteristics of the bill to be tested, and a description of how to generate the bill to be tested; when the bill to be tested is a blockchain bill, the bill description page includes a description of the blockchain bill, a description of the advantages of the blockchain bill over traditional bills, and instructions on how to generate a blockchain bill.

[0076] Step 306: Display the media link of the bill to be detected on the bill description page, obtain the second trigger instruction of the media link from the bill description page, switch to the media page corresponding to the second trigger instruction, and play the media information corresponding to the bill to be detected.

[0077] Among them, the media link is the web page address of the network resource and the switching address of the local resource played in the form of media, wherein the media form includes video, audio and other forms; the second trigger instruction is used to trigger the switch from the ticket description page to the media page or pop up the media page on the ticket description page; the media information is the description of the ticket to be tested and the description of the method of generating the ticket to be tested played in the form of media.

[0078] Specifically, after obtaining the second trigger instruction of the media link, switch to the media page corresponding to the second trigger instruction, obtain the click operation of the play button and the selection operation of the media playback form from the media page, and trigger the playback of the media information corresponding to the bill to be detected. The media link of the bill to be detected may include a bill description media link and a bill generation method media link. After obtaining the second trigger instruction of the bill description media link, switch to the media page of the bill description corresponding to the second trigger instruction, wherein the media page of the bill description page can be suspended on the bill description page in the form of a floating window, obtain the click operation of the play button and the selection operation of the media playback form from the bill description page, and play the media information of the bill description in the selected media form; after obtaining the second trigger instruction of the bill generation method media link, switch to the media page of the bill generation method corresponding to the second trigger instruction, wherein the media page of the bill generation method can be suspended on the bill description page in the form of a floating window, obtain the click operation of the play button and the selection operation of the media playback form from the bill generation method page, and play the media information of the bill generation method in the selected media form.

[0079] In the above-mentioned bill detection method, in the steps of switching the ticket description page of the bill to be detected and playing the media information corresponding to the detected bill, the inspection result is displayed on the display interface corresponding to the preset page, and the inspection result includes the bill description link address of the bill to be detected; a first trigger instruction of the bill description link address is obtained from the display interface, and the bill description page of the bill to be detected corresponding to the first trigger instruction is switched to, or the bill description page of the bill to be detected corresponding to the first trigger instruction can be popped up; the media link of the bill to be detected is displayed on the bill description page, and a second trigger instruction of the media link is obtained from the bill description page, and the media page corresponding to the second trigger instruction is switched to or the media page corresponding to the second trigger instruction is popped up, and the media information corresponding to the bill to be detected is played, which can help users master the use of the bill to be detected, improve the authenticity of the bill, save the time of generating bills, and simplify the process of generating bills.

[0080] In another embodiment, Figure 4 As shown, a bill detection method is provided, which is applied to Figure 1 The terminal 102 in the example is used as an example to illustrate, and the following steps are included:

[0081] Step 402, obtain the graphic code of the bill to be tested, extract the link of the graphic code, the link includes the bill hash value, and obtain the inspection element corresponding to the bill hash value from the corresponding database according to the bill hash value.

[0082] Step 404, obtain the domain name in the link of the graphic code, and switch to the preset page corresponding to the domain name.

[0083] Specifically, the verification domain name is the web address corresponding to the verification page. After obtaining the verification domain name in the link of the graphic code, it is triggered to switch to the preset page corresponding to the verification domain name, or it can be a pop-up window that pops up the preset page corresponding to the verification domain name. The verification domain name can be a secondary verification domain name corresponding to the preset page. For example, the obtained verification domain name is the web address baidu.com of the Baidu engine. By switching to the query page of the Baidu engine after triggering, the query information can be entered in the input box of the Baidu engine to obtain the query result corresponding to the query information.

[0084] Step 406, adding the extracted verification elements to the preset page.
