Detailed Description
It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
The application provides a certificate machine-readable method, in an embodiment of the certificate machine-readable method, referring to fig. 1, the certificate machine-readable method comprises:
step S10, receiving original data obtained after an equipment manufacturer reads a certificate to be read, wherein the equipment manufacturer does not encode the original data;
and step S20, carrying out encoding processing on the original data locally, and sending the encoded data obtained after encoding to an upper layer application so as to enable the upper layer application to process the encoded data.
In this embodiment, the document machine-readable method is applied to a document machine-readable device, the document machine-readable device belongs to a document machine-readable apparatus, and the document machine-readable apparatus belongs to a document machine-readable system.
In this embodiment, the certificate machine-readable system further includes an equipment manufacturer.
In this embodiment, the device manufacturer may include a reader (hardware device), a drive library, and the like, as shown in fig. 4.
As an example, the equipment manufacturer is an equipment manufacturer approved by the relevant department (allowing the relevant certificate to be read, etc.).
In this embodiment, the driver library of the equipment manufacturer interacts with the hardware equipment to read the information in the related certificate.
As an example, information in the identification card, such as name, gender, ethnicity, head portrait data, etc., is read from a chip in the identification card by the equipment manufacturer, and placed in an equipment manufacturer driver library, through which the user obtains the identification card information.
In the related art, the equipment manufacturer only supports GBK coding, but GBK coding does not support rarely used words (further, the user receives data of messy codes) under the strong standard of GB2022 required by people recently.
In the related art, an equipment manufacturer only supports machine-readable certificates in a fixed format, and when the types of the machine-readable certificates need to be increased, the equipment manufacturer needs to be driven and upgraded.
That is, in the present application, the technical background aimed at is:
the current reading of credentials (information in a chip) such as an identity card basically adopts equipment manufacturers approved by related departments, and the related information such as name, gender, ethnicity, head portrait data and the like is read from the chip through the interaction of a device manufacturer development driving library and hardware equipment, and after a user obtains the identity card information through the driving of the equipment manufacturers, service processing is carried out in a user system, such as the verification of the credentials information and the like in the display and transaction processes. Because the certificate information is provided by the equipment manufacturer, the conditions of rarely used word support, machine-readable certificate type addition and the like depend on upgrading and reconstruction driven by the equipment manufacturer (meanwhile, the conditions depend on codes used for text information in the reading process of the manufacturer, and most of the codes are GBK codes), and the requirements of the latest GB2022 strong standard of people on rarely used word support cannot be met.
In this embodiment, the device manufacturer only needs to obtain the original data (the original data is only a byte) of the certificate to be read, and does not need to encode the corresponding data, and the conditions that the certificate needs to support the rarely used word and add the type of the machine-readable certificate are actually associated with subsequent encoding and other processing (but the original data is locally encoded in the application), so that the certificate needs to support the rarely used word and add the type of the machine-readable certificate, and the like, and the certificate can be processed (encoded and the like) in the corresponding system of the user without depending on the driving upgrade of the device manufacturer, thereby realizing the requirement of practical application.
The method comprises the following specific steps:
step S10, receiving original data obtained after an equipment manufacturer reads a certificate to be read, wherein the equipment manufacturer does not encode the original data;
the certificate machine-readable method is applied to a certificate machine-readable device, and the certificate machine-readable device can be a PC (personal computer) or a mobile terminal.
In this embodiment, the device manufacturer reads the document to be read by its reader and then obtains the original data, which is a byte data stream.
In this embodiment, the device manufacturer does not encode the original data, but directly transmits the original data to the user.
In this embodiment, it is clear that the support of the rarely used word, the certificate structure, etc. is because the support of the encoding and decoding of the rarely used word is performed.
It should be clear that the device manufacturer etc. first reads the original data (byte data stream) in the certificate chip and then encodes and decodes the original data stream for use by the user.
In the related art, the reading of the original data, and the encoding and decoding, etc., are performed in the equipment factory.
In the related art, since the original data is read, encoded, decoded, etc. in the equipment factory, if the equipment factory recognizes the original data, if the equipment factory only supports GBK encoding, but GBK encoding cannot encode the uncommon word, the data decoded to the user is scrambled.
In the related art, since the original data is read, encoded, decoded, etc. in the equipment manufacturer, if the type of the machine-readable certificate needs to be added, or the rarely used word needs to be read, the equipment manufacturer needs to be upgraded.
In the application, because the original data is read only in the equipment manufacturer, other coding components supporting the encoding of the rarely used words can be used for encoding the read original data, and the upgrading depending on the equipment manufacturer is not needed.
And step S20, carrying out encoding processing on the original data locally, and sending the encoded data obtained after encoding to an upper layer application so as to enable the upper layer application to process the encoded data.
In this embodiment, the original data is locally encoded at the user side.
In this embodiment, the user locally uses the Unicode encoding format, the UTF8 encoding format, the GBK encoding format, and the like to encode the original data, and sends the encoded data obtained after encoding to the upper layer application, where the current equipment factory only supports the GBK encoding format. As shown in fig. 4.
In this embodiment, the Unicode (international text coding standard, text representing rule in computer) coding format may be used for coding, in addition, the target coding format may also be variable length coding format UTF-8 (8-bit Unicode Transformation Format), where the second number of bits of each coding unit of UTF-8 is less than the first number of bits of each first coding unit of Unicode format, in this embodiment, since the second number of bits of each second coding unit of UTF-8 coding format is less than the first number of bits of each first coding unit of Unicode format, and since a text will not have too many bit lengths, coding of data (data after UTF-8 coding is also transmitted) using UTF-8 can reduce resource waste.
That is, in the present embodiment, UTF-8 is preferentially used for encoding data.
In this embodiment, when the certificate is read, the dependence on the equipment manufacturer is greatly reduced, and data and drive decoupling is realized. Under the conditions of newly-added machine-readable credentials, data structure change and the like, the system in the user can be automatically modified without factory driving modification.
Referring to fig. 2, the step of locally encoding the original data and transmitting the encoded data obtained after encoding to an upper layer application includes:
step S21, determining a target output coding format, wherein the target output coding format is set according to output requirements;
in this embodiment, on the basis of fully supporting the reading of the rare words of the certificate, the data with different codes can be individually output, that is, the target output coding format is set according to the output requirement.
For example, if a need to encode using a Unicode encoding format is detected, the target output encoding format is determined to be the Unicode encoding format.
If a need to encode using the UTF8 encoding format is detected, the target output encoding format is determined to be the UTF8 encoding format.
In this embodiment, the target output encoding format may be determined by the user, or may be determined by another user.
And S22, carrying out encoding processing of the target output encoding format on the original data locally, and sending the encoded data obtained after encoding to an upper layer application.
In this embodiment, the encoding process of the target output encoding format is performed on the original data locally, so as to meet the personalized encoding requirement, and the encoded data obtained after encoding is sent to an upper layer application.
In this embodiment, the upper layer application may be a business application.
In this embodiment, the specific business application may be a loan application or an credit loan business, etc., which is not particularly limited.
In this embodiment, the read certificate information may be directly output for display.
The step of locally encoding the original data and transmitting the encoded data obtained after encoding to an upper layer application comprises the following steps:
a1, analyzing target bytes used for representing the types of credentials in the original data;
in this embodiment, specifically describing the machine-readable process of the certificate, a byte data stream is obtained first, and a user first parses a target byte in the byte data stream, where the target byte is used to represent the type of the certificate.
A2, determining a target type corresponding to the certificate to be read according to the target byte;
the user side determines the target type corresponding to the certificate to be read according to the target bytes, specifically, the type of the bytes (target bytes) at the determined positions in the byte data stream, and determines the target type corresponding to the certificate to be read.
Step A3, determining a target structure of the target type certificate stored locally, and analyzing information in the certificate to be read according to the target structure;
in this embodiment, a target structure (such as a blank portion, a name portion, an address portion, etc.) of the target type document stored locally is determined, and information in the document to be read is parsed according to the target structure.
And step A4, carrying out coding processing on the analyzed information, and sending coded data obtained after coding to an upper layer application.
After obtaining the information in the certificate to be read, carrying out coding processing on the analyzed information, and sending coded data obtained after coding to an upper layer application.
Specifically, the following is a specific description taking an identity card as an example:
the identity card equipment manufacturer provides a driver and then reads the byte stream of original text information (256 bytes), head portrait information (1024 bytes) and the like in the certificate chip.
After the user system reads the returned data through the standard API, the returned data is analyzed through various certificate data storage structures provided by related departments to obtain the type of the certificate, so that the complete text information of the type of the certificate is analyzed according to the information structures of different types of the certificate, and the analyzed complete text information can be output to an upper layer application for use through various codes (including Unicode, UTF8, GBK and the like) according to different scene requirements.
Compared with the prior art that the certificate reading is completely dependent on the driving of an equipment manufacturer and is difficult to meet the requirement of practical application, the method and the device have the advantages that the original data obtained after the receiving equipment manufacturer reads the certificate to be read are obtained, wherein the equipment manufacturer does not encode the original data; and carrying out encoding processing on the original data locally, and sending the encoded data obtained after encoding to an upper layer application for the upper layer application to process the encoded data. It can be understood that in the present application, the device manufacturer only needs to obtain the original data of the certificate to be read, and does not need to encode the corresponding data, and the conditions that the certificate needs to support the rarely used word, add the machine-readable certificate type, etc. are actually associated with the subsequent encoding, etc. (while in the present application, the original data is encoded locally), so that the certificate needs to support the rarely used word, add the machine-readable certificate type, etc. and can be processed (encoded, etc. in the corresponding system of the user, without depending on the driving upgrade of the device manufacturer, so as to further realize the requirements of practical application.
Further, based on the above embodiment, the present application provides another embodiment of the machine-readable method of credentials, in which, when the structure of the corresponding credentials changes, the structure of the corresponding credentials stored locally also changes synchronously.
In this embodiment, when the structure of the corresponding certificate changes, the structure of the corresponding certificate stored locally changes synchronously, so that the complete text information of the certificate can be accurately analyzed according to the information structure of different certificate types, and the analyzed complete text information can be output to the upper layer application for use through various codes (including Unicode, UTF8, GBK, etc.) according to different scene requirements.
The credentials to be read can be a newly added machine-readable credential type;
the step of locally encoding the original data and transmitting the encoded data obtained after encoding to an upper layer application comprises the following steps:
and step B1, locally storing the structural information of the newly-added machine-readable certificate type.
In this embodiment, the structure information of the newly added machine-readable certificate type is also stored locally, so that a foundation is provided for the structure of the corresponding certificate stored locally to be changed synchronously when the structure of the corresponding certificate is changed.
Further, based on the above embodiment, the present application provides another embodiment of the machine-readable method for credentials, in which the target output encoding format supports encoding and decoding of rarely used words. In this embodiment, since the target output encoding format supports encoding and decoding of rarely used words, the condition of messy codes can be avoided.
