Detailed Description

In the following description, for purposes of explanation and not limitation, specific details are set forth such as the particular system architecture, techniques, etc., in order to provide a thorough understanding of the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.

Existing instant tickets, as shown in fig. 1, may generally include a substrate 100, a playing area 110, and a scratch-off layer 120 overlying the playing area. At the time of the prize, the user, after removing scratch-off layer 120, determines whether to win based on the prize content (e.g., including "My number" and "winning number" as is common) presented in game field 110. Because the scratch-off layer 120 may be damaged during the transportation and circulation process of the instant ticket, the instant ticket drawing data is directly displayed after the damage, so that the instant ticket drawing data is revealed before the instant ticket is not sold, and the instant ticket drawing safety is affected to a certain extent.

In order to solve the problems in the prior art, the technical scheme of the application is provided. In order to illustrate the technical scheme of the application, the following description is made by specific examples.

Referring specifically to fig. 2A, fig. 2A is a schematic diagram illustrating an embodiment of an instant ticket according to an embodiment of the present application, including:

a substrate 200 and an image identifier 210 printed on the substrate;

the image identifier 210 is used to indicate encrypted drawing data, which is data indicating whether the instant ticket wins or not.

Specifically, after the image identifier 210 is scanned by a specific device or a device in which a specific scanning program is installed, the image identifier 210 may be parsed by the scanning device to obtain encrypted lottery drawing data. The drawing data is data indicating whether the instant ticket wins or not. The image identifier may be, for example, electronic data similar to paper game data contained in a conventional instant on-play game area as shown in fig. 1. Specific common plain text prize data may include "my number" and "winning number", and after the user obtains the plain text prize data, the user may determine whether the instant ticket wins by comparing the "my number" with the "winning number".

The encryption of the prize drawing data may be performed during printing, that is, during drawing. Firstly, after the device or printing system for printing the instant ticket obtains the plain text lottery drawing data of the instant ticket with a certain specific serial number, the special device can encrypt the lottery drawing data by utilizing a symmetric encryption algorithm or an asymmetric encryption algorithm, and the key used for encryption and decryption is distributed and distributed by the key management device. When the user draws the instant ticket, the user needs to scan the image identifier 210 by using a specific device or a device provided with a specific scanning program, analyze the encrypted drawing data to obtain the encrypted drawing data, and then decrypt the encrypted drawing data by using a key obtained in advance from the key management device, thereby obtaining plain text drawing data and judging whether the instant ticket is drawn.

In addition, it should be noted that, in the embodiment of the present application, the base 200 may be the same as or different from the existing base material that is to be billed, and the image identifier 210 may be a two-dimensional code, a one-dimensional code, or a combination of two-dimensional code and one-dimensional code, and the specific form may be to select a suitable bar code according to the data amount of the encrypted lottery drawing data, which is not limited herein.

In a particular embodiment, the image identifier 210 also indicates the serial code and/or payment code of the instant ticket. Specifically, the image identifier 210 may parse the instant ticket serial number and/or the payment code in addition to the encrypted lottery data after being scanned by a specific device or a device installed with a specific scanning program. The serial number is used for uniquely identifying the instant bill, and the payment code is used for the scanning device to carry out payment operation on the instant bill according to the payment code.

It should be noted that, the image identifier 210 may be a plurality of types of bar codes, such as a two-dimensional code, a one-dimensional code, or a combination of a one-dimensional code and a two-dimensional code, or other self-defined ordered symbols or a set of ordered patterns that can be converted by data, such as a combination pattern of a pattern and a two-dimensional code, a recognizable ordered pattern directly generated by using data, and the like. Since the amount of information that can be contained in the different types of image identifiers 210 is different, in practical designs, an appropriate type may be determined according to the amount of information that needs to be indicated by the image identifier 210, and thus the form of the specific image identifier 210 is not particularly limited in this embodiment.

In a specific embodiment, fig. 2B is a schematic diagram of another embodiment of an instant ticket according to an embodiment of the present application, including:

the instant bill also includes a serial number bar code 220 and/or a payment bar code 230 printed on the substrate. In particular, compared to the foregoing simultaneous indication of the serial code and/or the payment code on the image identifier 210 in the instant invoice shown in fig. 2A, the present embodiment provides a new design: the serial code may be a serial number bar code 22 and the payment code may be a payment bar code 230, either simultaneously or separately printed on the substrate 200 upon which the ticket is to be placed. Meanwhile, the specific form of the serial number bar code 220 and the payment bar code 230 may be the same as or different from the image identifier 210, and are not particularly limited herein.

In another specific embodiment, referring specifically to fig. 2C, fig. 2C is a schematic diagram of an embodiment of an instant ticket according to an embodiment of the present application, including:

in the instant schematic drawing shown in fig. 2A or 2B, the image identifier 210 may also be covered on its surface with a scratch-off layer 240. Specifically, after the image identifier 210 is printed on the substrate 200, a scratch-off layer 240 may be printed on the surface of the image identifier 210, so as to further improve the security of the prize drawing data.

From the above technical solutions, the embodiment of the present application has the following advantages:

in the technical scheme, the bill consists of a matrix and an image identifier printed on the matrix, and the encrypted lottery drawing data is indicated by the image identifier. Compared with the existing plain text lottery drawing data which is displayed on the instant ticket, the scheme has the advantage that the encrypted lottery drawing data is displayed on the ticket surface, so that the scheme has higher security.

Referring specifically to fig. 3, fig. 3 is a schematic diagram illustrating an embodiment of a method for displaying a transaction according to an embodiment of the present application, including steps S301 to S303:

s301, the first client device responds to the first user operation, scans and analyzes the image identifier printed on the instant bill, and obtains encrypted data corresponding to the image identifier.

In a specific embodiment, the first client device scans, i.e., invoices, the image identifier exposed after scraping the scratch-off layer in response to a first user operation, e.g., in response to a user clicking a scan button.

The first client device may be a terminal device having a scanning function, and a program for resolving an image identifier may be preset on the terminal device. Typically, the first client device may include any terminal such as a mobile phone, a tablet computer, or a barcode scanner. The first client device obtains the encrypted data indicated by the image identifier after scanning and analyzing the image identifier of the billing. Wherein the encrypted data includes encrypted lottery drawing data of the instant ticket. The drawing data is data indicating whether or not the drawing is winning.

The program can be a special terminal application, when the image identifier is scanned to acquire the encrypted data, a user can log in an account, can perform offline or online scanning, can store the record of scanning the instant invoice in the local of the first client device, and can upload the scanned record to the server. The user may then query the scanned instant ticket record via the first client device.

In a specific embodiment, after the user downloads and installs the dedicated terminal application on the first client device, user registration needs to be completed, on one hand, the authentication server may audit the user identity according to a preset rule, and on the other hand, the authentication server may issue a digital certificate to the first client device after the user identity audit is passed. The user device may be securely authenticated based on the digital certificate before the business process begins. The user equipment can be subjected to multiple security authentications based on the digital certificate in the whole business process. And stopping executing the business process or exiting the business process once the user equipment safety certification is not passed.

It should be noted that the authentication server may be the same server as the key server described below, or may be a different server.

S302, the first client device decrypts the encrypted data by using the first decryption key from the key server to obtain the prize-winning data.

In a specific embodiment, after the first client device obtains the encrypted data, a prompt interface for decrypting the encrypted data may be popped up at the interface of the first client device. At this time, the first client device decrypts the decrypted data by using the first decryption key from the key server, and obtains the prize-winning data. It should be noted that, the first decryption key is stored in the key server in advance, and each of the instant serial numbers corresponds to a unique first decryption key. The first client device may acquire the first decryption key by responding to an input operation of the user after the user learns the first decryption key, or actively transmitting a query request to the key server to acquire the first decryption key. The key server may be an operator or supervisor controlled server device, i.e. an invoicing, for managing and issuing the first decryption key.

S303, the first client device displays the lottery drawing data.

In a specific embodiment, after the first client device obtains the prize data, a reminder interface may be generated, on which the prize data is displayed. Specifically, when displaying, the drawing data may be displayed in the form of text or image, or a combination of text and image.

In another specific embodiment, when the first client device displays the drawing data of the instant ticket on the prompt interface, prompt information of whether the instant ticket wins or not may also be displayed.

in the embodiment of the application, the image identifier is printed on the instant bill and is used for indicating the encrypted lottery drawing data. When drawing a prize, the encrypted drawing data is decrypted by using a first decryption key from a key server to obtain and display the drawing data, so that a method for displaying and processing based on the instant drawing a prize flow is provided.

Based on the instant billing shown in any one of the embodiments of fig. 2A to 2C, referring specifically to fig. 4, fig. 4 is a schematic diagram of one embodiment of a key distribution method according to an embodiment of the present application, including steps S401 to S403:

s401, the key server receives a first query request sent by the first client device to acquire a first decryption key, where the first query request includes a serial number.

In a specific embodiment, the first query request is a query request for obtaining a first decryption key, where the query request includes a sequence number of an instant bill, and the first decryption key is a key locally managed by a key server and corresponding to the sequence number.

S402, the key server obtains a first decryption key corresponding to the serial number from the local query.

In a specific embodiment, the key server stores the correspondence between different serial numbers and decryption keys. After the key management server receives the first inquiry request, a first decryption key corresponding to the serial number is determined according to the serial number and the corresponding relation included in the first inquiry request.

S403, the key server sends a first decryption key to the first client device, wherein the first decryption key is a key adopted when decrypting the encrypted data.

In a specific embodiment, after determining the first decryption key, the key server sends the first decryption key to the first client device. Wherein the first decryption key is a key required for decrypting the encrypted data on the instant invoice.

In the embodiment of the application, the image identifier is printed on the instant bill and is used for indicating the encrypted lottery drawing data. When the lottery is drawn, the key server issues a first decryption key to the first client device, and instructs the first client device to decrypt the encrypted lottery drawing data by using the first decryption key, so as to obtain and display the lottery drawing data, thereby providing a key distribution method based on the instant lottery drawing process.

Based on the instant invoices shown in fig. 2A to 2C, referring specifically to fig. 5A, fig. 5A is a schematic diagram of an embodiment of a method for displaying a transaction according to an embodiment of the present application, including steps S501 to S506:

s501, the first client device responds to a second user operation and sends a first query request to the key server, wherein the first query request comprises a serial number of an instant bill.

In a specific embodiment, the first query request may be a request message generated by the first client device in response to a user operation. For example, as shown in fig. 5B, the first client device opens the relevant website in response to the user operation, and responds to the user-entered instant-invoicing serial number, thereby sending a first query request to the key server to query the first decryption key corresponding to the serial number. The first query request may also be a request message automatically generated by the client device after detecting that the user has completed payment for the instant ticket. For example, if the image identifier of the instant ticket is further used to indicate a payment code, or if the instant ticket is printed with a payment bar code, the first client device obtains the payment code after scanning the image identifier or the payment bar code in response to the user operation, and automatically sends the first query request to the key server after successful payment according to the payment code.

In a specific embodiment, the first client device is responsive to a second user operation to send a first query request to the key server after the user authentication passes, the first query request including the instant-invoicing serial number. Specifically, the first client device may initiate authentication in response to the second user operation, and after the authentication is passed, send a first query request to the key server. For example, the first client device responds to the second user operation, loads the authentication interface, and if the acquired password input by the user on the authentication interface is the same as the preset password, the first client device sends a first query request to the key server; if the acquired password input by the user on the identity authentication interface is the same as the preset password, stopping the service flow, or prompting the user to input the password again. By means of encryption, the safety of the scheme is further improved.

S502, the key server obtains a first decryption key corresponding to the serial number from the local query.

S503, the key server sends a first decryption key to the first client device, where the first decryption key is a key used when decrypting the encrypted data.

It should be noted that steps S502 to S503 are similar to steps S402 to S403 in the embodiment shown in fig. 4, and will not be repeated here.

S504, the first client device responds to the first user operation, scans and analyzes the image identifier printed on the instant bill, and obtains the encrypted data corresponding to the image identifier.

The second inquiry request is an inquiry request for inquiring the acquisition record of the first decryption key, and the inquiry request can comprise a serial number. Thereafter, the first client device receives and displays the acquisition record about the first decryption key sent by the key server. Through the obtained record, the user can judge whether the instant bill is queried by other users in advance for the first decryption key, if so, the instant bill can be determined to be possibly a waste bill, otherwise, the instant bill is a normal bill. The acquisition record may include an indication of whether the first decryption key has been acquired, or may include time information acquired if the first decryption key has been acquired before, and so on. The embodiment provides a method for inquiring whether the bill is the waste bill or not for the user, thereby avoiding the occurrence of the existing secondary selling condition caused by reprinting after the scratch-off image layer can be scraped.

In the embodiment of the application, the technical scheme provides a display processing method, wherein an image identifier obtained by converting encrypted data is printed on the ticket surface of the instant ticket, and the encrypted data is data obtained by encrypting the lottery drawing data indicating whether the instant ticket wins or not. When drawing a prize, the client device scans the image identifier to obtain the encrypted data, and then decrypts the encrypted data by using the first decryption key obtained from the key server, so as to obtain and display the prize drawing data, thereby providing a method for displaying based on the instant drawing a prize drawing flow.

In a specific embodiment, before step S403 or step S503, the key server further needs to check whether the ticket is in an active state, if so, the key server performs step S403 or step S503, otherwise, the key server refuses to issue the first decryption key to the first client device.
