Description

Method and system for processing information by utilizing hierarchical graphic coding data

Technical Field

The present invention relates to the field of information processing, and more particularly, to a method and system for information processing using hierarchical graphics coding data.

Background

The popularity of coded data enables devices with computing capabilities to read, process, and express information. At present, the trend of information processing by two-dimensional codes of mobile devices is more and more common. Two-dimensional codes are a very popular encoding method applied to mobile devices in recent years, and can store more information and represent more data types than traditional bar codes.

The two-dimensional code records data symbol information by using black and white patterns which are distributed on a plane (in a two-dimensional direction) according to a certain rule and a certain specific geometric figure. In terms of code encoding, the two-dimensional code skillfully utilizes the concepts of '0' and '1' bit streams forming the internal logic basis of a computer, and uses a plurality of geometric shapes corresponding to binary systems to represent literal numerical information. The image input device or the photoelectric scanning device can automatically read the two-dimensional code to realize automatic information processing. Two-dimensional codes have some commonalities in barcode technology: each code system has a specific character set, each character occupies a certain width, and has a certain checking function. In addition, the two-dimensional code also has a function of automatically recognizing information on different lines and a function of processing a figure rotation change point.

Currently, the two-dimensional codes are all square in shape, for example, quick response QR codes. As shown in fig. 2, the QR code 200 is square and has black and white. Fig. 2 is a schematic diagram of a QR code in the related art, in which 3 of 4 corners of the QR code 200 are provided with a square pattern which is small and looks like a "square" word. These 3 patterns are a scale that helps the decoding software locate the QR code 200 so that the user does not need to align and scan at any angle, yet can correctly read the data.

However, when a user of the two-dimensional code needs to perform an information processing task that is commonly completed by a plurality of devices, a separate two-dimensional code needs to be generated for each device and the generated two-dimensional code needs to be identified so that each device can know that the current two-dimensional code relates to the commonly completed information processing task. This method of the prior art lacks flexibility and is prone to confusing two-dimensional codes.

Fig. 1 is a flow chart of a method 100 for information processing using hierarchical pattern encoded data in accordance with a preferred embodiment of the present invention. As shown in fig. 1, method 100 begins at step 101.

In step 101, an information processing request for a collaborative service is received, wherein the information processing request comprises information content associated with the collaborative service and a structure description file of the collaborative service. The cooperative service is a service that is collectively completed by a plurality of cooperative devices. Wherein when the provider of the graphics coded data determines that the generated graphics coded data relates to the collaborative service, an information processing request for the collaborative service is generated. The information content associated with the collaborative service is task information required to complete the collaborative service. The structure description file of the collaborative service is used for indicating the logical structure of the collaborative service, and the collaborative service can be divided into a plurality of sub-services based on the structure description file. Wherein each sub-service of the plurality of sub-services corresponds to a collaborative task to which the respective collaborative device relates.

Step 102, parsing the structure description file of the collaborative service to determine a plurality of collaborative devices related to the collaborative service and a collaborative task related to each collaborative device. The method specifically comprises the following steps: parsing a structure description file of the collaborative service to determine a plurality of sub-services of the collaborative service; determining a cooperative device involved by each sub-service in a plurality of sub-services; analyzing the service content of each sub-service to determine a cooperative task; and determining the cooperative task involved by each cooperative device.

In step 103, original graphic coded data including data information is generated according to the information content associated with the collaborative service, and the data information in the original graphic coded data is divided into a plurality of sub data information based on the collaborative task related to each collaborative device. Wherein generating original graphically encoded data comprising data information from information content associated with the collaborative service comprises: information content associated with the collaborative service is taken as data information, and original graphic encoding data including the data information is generated. The dividing of the data information in the original graphic coding data into a plurality of sub data information based on the cooperative task related to each cooperative device includes: determining collaboration data associated with a collaboration task to which each collaboration device relates; and dividing the data information in the original graphic coding data into a plurality of sub data information based on the cooperative data of each cooperative device.

At step 104, an association relationship between the plurality of cooperative devices is determined, and a hierarchical relationship is determined for each of a plurality of sub data information based on the association relationship. The association relationship among the plurality of cooperative devices includes: peer relationships, superior relationships, subordinate relationships, and conditional relationships. Determining a hierarchical relationship for each sub-data information of the plurality of sub-data information based on the association relationship comprises: when the relationship is a peer relationship or a conditional relationship, determining a hierarchical relationship of each subdata information in the plurality of subdata information as the same hierarchical relationship; and when the relationship is a higher-level relationship or a lower-level relationship, determining the hierarchy relationship of each sub-data information in the plurality of sub-data information as different hierarchy relationships.

At step 105, the original graphics-coded data is divided into a plurality of hierarchical graphics-coded data based on the hierarchical relationship of each sub data information, and each hierarchical graphics-coded data is assigned to a corresponding cooperative device for information processing. Header information is set for each hierarchical pattern encoding data, wherein the header information of each hierarchical pattern encoding data is the same as, different from, or related to the header information of the generated original pattern encoding data.

Alternatively, the present application receives a code division request for division of the generated original graphic encoding data. And analyzing the code division request to determine the number N of the subcodes. And dividing data information included in the generated original graphic coding data into N pieces of sub-data information. And dividing the generated original graphics coded data into N pieces of sub-coded data according to the N pieces of sub-data information. Each of the N sub-coded data is transmitted to a respective user equipment, wherein each user equipment is capable of receiving at least one sub-coded data. The title information is set for each sub-coded data, wherein the title information of each sub-coded data is the same as, different from or related to the title information of the generated original graphic coded data. A code division request for dividing specific sub-encoded data is received, and the specific sub-encoded data is divided into a predetermined number of grandchild encoded data according to the code division request.

It should be understood that the data information in the original graphics-encoded data may be equally divided into N parts of sub-information, and each of the N parts of sub-information is used to form each of the N sub-encoded data. The N parts of sub information have a sequence, and the sequence depends on the content of the data information, namely the N parts of sub information can form the data information after being combined according to the sequence numbers without modifying the sequence. In addition, the data information in the original graphics coding data can be divided into N parts of sub information unevenly. Alternatively, the data information in the original graphics coding data may be divided into N pieces of sub information according to a semantic structure, a separator structure, or the like.

As is apparent from the above description, a plurality of hierarchical pattern encoded data may be located at different levels, wherein each pattern encoded data may be divided into at most a predetermined number of pattern encoded data as subcodes. Hierarchical pattern coding data obtained by dividing original pattern coding data is positioned at the next level of the original pattern coding data. The new hierarchical graphics encoding data resulting from dividing a particular hierarchical graphics encoding data is located at a next level of the particular hierarchical graphics encoding data. For another example, when the number N of the sub-codes is 8, the original graphics encoding data can be divided into 8 sub-encoding data at most, and each sub-encoding data can be divided into 8 grandchild encoding data at most, and so on.

According to an embodiment of the present application, before the receiving an information processing request for a collaborative service, the method further includes:

application description information associated with a user device is obtained, and a plurality of applications desiring information transfer by graphically encoded data is determined based on the application description information. The application description information includes a plurality of description items, and the format of each description item is < application name, application type, associated device type, encoded data flag >. For example, < Payment Bao, Payment type, iOS, Yes > and < Payment Bao, Payment type, Andriod, Yes > are used to indicate that the Payment Bao application is of a Payment type application, and whether it is an iOS operating system or Andriod operating system, the graphical encoded data needs to be used. In general, description items may be set by a provider of an application, a provider of an operating system, an application store, the user device itself, and application description information associated with the user device is formed from a plurality of the set description items. Therefore, each application which wants to carry out information transmission through the graphic coded data can be determined through the analysis of each description item in the application description information.

And determining the maximum information quantity required by each application for information transmission through the single graphic coded data according to the information transmission requirement of each application in the plurality of applications. The information transfer requirements of each application are determined according to the data integrity required when each application carries out information transfer through the pattern coding data. The data integrity is the maximum possible data volume, namely the peak data volume, required for ensuring that information is not divided when each application carries out information transmission through the pattern coding data. Where the information transfer requirements include the amount of peak data involved in order to meet data integrity. The maximum information quantity required when each application carries out information transmission through single graph coded data is determined according to the peak data quantity. For example, the present application may use the peak data amount as the maximum information amount, 1.2 times the peak data amount as the maximum information amount, and 0.9 times the peak data amount as the maximum information amount.

The graphical interface of each application for providing the graphical encoded data is parsed to determine a display range that each application can use to display the graphical encoded data. The graphical interface is an interface for information transmission by utilizing graphically coded data of each application. For example, a graphical interface for a payment instrument for providing graphically encoded data includes: two-dimensional code for showing payment, bar code for showing payment, bank card information, member level, prompt information and the like. The display range is a range for displaying graphically encoded data in the graphical interface, i.e., a region of the graphical interface representing the two-dimensional code for payment. In the present application, the shape of the display range is rectangular and the shape of the image area is rectangular. That is, the shape of the display range is a square or a rectangle and the shape of the image area is a square or a rectangle. As shown in fig. 3, the shape of the display range is a rectangle, and the shape of the image area is a rectangle.

And determining the coding ratio of each image area for displaying the graphics coding data based on the display range and the maximum information amount for displaying the graphics coding data. Wherein determining the encoding ratio of each image region to which the graphically encoded data is applied based on the display range and the maximum amount of information for displaying the graphically encoded data comprises: and determining the length and the width of the display range for displaying the graphic coded data. Currently, the external shape of a mobile terminal (e.g., a mobile phone) is mostly rectangular or approximately rectangular. For this reason, the display plane of the display screen of the mobile terminal is also typically rectangular or approximately rectangular, i.e. both the mobile terminal and the display screen present a width and a length. Generally, the length is greater than the width, and the length and width do not vary in the present application with the lateral and longitudinal placement of the mobile terminal. The length and width of the display range determined by the present application is the largest display area or range that can be used to display the graphically encoded data.

And determining the transverse coding quantity of each image area applied to the graphics coding data according to the width of the display range. Typically, the width occupied by the horizontal encoding of the image area for the graphics encoded data is less than the width of the display range. As shown in fig. 3, the width of the horizontal encoding is, for example, the distance between the two main scales 311-1 and 311-2 (including themselves) located at the upper part of the image encoded data, and the width of the vertical encoding is, for example, the distance between the two main scales 311-2 and 311-3 (including themselves) located at the upper part of the image encoded data. It should be understood that when the graphic coded data contains less data information, the width of the graphic coded data does not occupy the width of the display range. That is, the width of the display range may be regarded as the maximum width of an image area for graphics-encoded data per application, and the maximum number of lateral encodings is determined based on the maximum width of the image area and the size of a symbol (or 1/4 symbols).

And determining the longitudinal coding number of each image area applied to the graphics coding data according to the length of the display range and the maximum information amount. Wherein determining the number of vertical encodings per image area applied for graphically encoded data based on the length of the display range and the maximum amount of information comprises: the preselected number of vertical codes is determined based on the maximum amount of information and the number of horizontal codes. The maximum information amount related to the data information of the pattern coded data determines the area of the pattern coded data, and for example, the area of the pattern coded data can be determined based on the maximum information amount and the size of the symbol (or 1/4 symbols). For example, in the case where the number of horizontal encodings of an image region for graphics-encoded data is determined, the number of vertical encodings per image region to which graphics-encoded data is applied may be determined in accordance with the length of the display range and the maximum amount of information. This is because the maximum information amount of a single pattern coded data can determine the number of symbols of this pattern coded data, and the number of vertical codes can be determined from the number of symbols and the number of horizontal codes.

When it is determined that the length of the display range can accommodate the preselected number of vertical encodings, the preselected number of vertical encodings is determined as the number of vertical encodings per image area applied for graphically encoded data. When it is determined that the length of the display range cannot accommodate the preselected number of vertical encodings, the maximum vertical encodings that the display range can accommodate is determined as the number of vertical encodings per image area to which the graphic encodings are applied.

It should be understood that, for a single graphic coded data, the smaller the size (display size or presentation size) of a symbol or 1/4 symbol (1/4 symbol is an elementary data unit of the graphic coded data, representing 1 or 0), the more information (system information, header information, and data information) can be accommodated by the single graphic coded data.

The encoding ratio of each image region to which the image encoding data is applied is determined based on the number of horizontal encodings and the number of vertical encodings. For example, if the number of horizontal codes of a specific application is 62 and the number of vertical codes is 100, then the coding ratio of the image area for graphics coded data of the specific application is 0.62. In a preferred embodiment of the present application, the coding ratio is 0.618.

When a specific application of the plurality of applications desires to perform information transfer, the specific application generates original graphics encoding data conforming to the encoding ratio and performs information transfer based on the original graphics encoding data conforming to the encoding ratio. The original graphic encoding data in conformity with the encoding ratio may include three main scales, a system information area and a backup information area. Three of which are used to locate the graphics encoded data for the scanner or decoder. The main scaling is responsible for image recognition and positioning of the graphics encoding data.

The system information region includes two symbols, where each symbol may indicate 4 binary data bits or bits. The system information area represents the size level of the graphic encoded data, i.e., levels 0 to 63, using 6 bits, and represents the error correction level of the graphic encoded data, i.e., levels 0 to 3, using 2 bits. The system information area is located in the upper left corner of the graphics coded data. The content setting of the backup information area is identical to that of the system information area, and the content in the system information area and the backup information area of the same pattern coded data is identical. The backup information area is located at the lower right corner of the graphic coded data. It should be appreciated that the backup information area and the system information area may be disposed at any reasonable location of the pattern encoded data.

Further, the original graphic encoding data in conformity with the encoding scale may further include sub-scalings, and the number of the sub-scalings may be 0 or at least one. The sub-scaling is used for auxiliary positioning, i.e. for auxiliary positioning of encoded data in the graphics encoded data. For example, sub-scaling is responsible for symbol positioning in graphically encoded data.

The graphically encoded data (e.g., month code) of the present application has a tamper-resistant mechanism.

Tamper-proofing purposes:

the month code contains header information and data information, and after the month code is generated, the two data must be matched with each other, so that the month code needs to be prevented from being forged by modifying one of the data by others.

Tamper-resistant conditions:

the month code containing only the data information does not need to be tamper-proof, i.e. the month code must contain header information and data information. The data information of the month code must be encrypted.

Tamper-proofing:

generating a month code: and generating a 128-bit hash string by using the header information, carrying out exclusive OR operation on the whole data information byte by using the hash string before encrypting the data information, and then encrypting the data.

Reading the month code: after the data information is decrypted, the 128-bit hash string generated by the header information is used for carrying out exclusive OR operation on the data information in a byte-by-byte mode, and the data information is restored.

Examples of applications of graphically encoded data (e.g., month code) of the present application include:

the encrypted information is transmitted using a month code. For example, by encrypting the month code in units of symbols or minimum coding units of the month code, the security of information transmitted by the month code is ensured.

Using pictures, information is transferred cryptographically between different software. For example, the encrypted month code is converted into a picture and information desired to be transmitted between different software of different mobile terminals is transmitted by picture transmission.

And performing group authentication, pipeline authentication and quality authentication by using the subcodes. For example, in testing a software project, an original month code is divided into a plurality of subcodes according to the number of test modules of the software project. And distributing each subcode to a corresponding testing department in charge of at least one testing module, and sending the associated subcode to a testing acceptance department when the testing department completes the testing of the testing module. When all subcodes are collected by the test acceptance department, the original month code is formed to confirm that the testing of the software project is completed.

For example, in the process of manufacturing a new energy automobile, the original month code is divided into a plurality of subcodes according to the stage number of the production line of the new energy automobile. Each subcode is distributed to a production department responsible for a respective single pipeline stage, and when the production department completes the manufacturing work of the pipeline stage to which it belongs, the associated subcode is sent to the entire vehicle integration department. When the whole vehicle integration department collects all the subcodes, the original month code can be formed to determine that the manufacturing of the new energy vehicle is finished.

For example, in the process of producing food or medicine, the original month code is divided into a plurality of subcodes according to the number of quality inspection departments that inspect the detailed quality of the food or medicine. And distributing each sub-code to a quality inspection department responsible for quality inspection, and sending the associated sub-code to a safety control department of the food or the medicine when the quality inspection department finishes the quality inspection of the indexes of the belonged food or medicine. When all the subcodes are collected by the food or drug safety control department, the original month code can be formed to confirm that the food or drug meets the safety requirements.

In the above example, when the test acceptance division, the entire vehicle integration division, or the food or drug safety control division does not receive all subcodes associated with the software project, the new energy vehicle, the food or drug, it may be determined that at least one test module of the software project failed the test, at least one component of the new energy vehicle is not manufactured, and at least one indicator of the food or drug does not meet the safety requirement.
