TECHNICAL FIELD
The present invention relates to the field of information processing technologies, and more particularly, to a two-dimensional code based information acquisition system and a method thereof.
BACKGROUND
A two-dimensional code is an important technology in the automatic identification of information, and is one of key and core technologies in the industry of Internet of Things. As a timely, accurate, reliable, and economical data input and transmission way, the two-dimensional code has been widely applied in many fields including industry, business, national defense, transportation, finance, medical treatment, hygiene, etc. However, the application field at current is mainly that a merchant provides information to a user based on the two-dimensional code, such as a website link, a commodity introduction, and other product information. Actually, the user needs to provide some personal information to the merchant or other information collection terminal in many occasions. For example, the user needs to provide a company name to the merchant for invoicing; and for another example, the user may also need to provide name, address, telephone, mailbox, ID Card No., and other information for information registration. However, for these applications at present, most applications in the prior art need to be filled or explained on site by the user, which not only needs a relatively long time period and has low efficiency, but also is easy to make mistakes.

Further, after the first processing module directly invokes the corresponding user information from the first storage module according to the user information type needed by the information acquisition end, the intelligent terminal may also amend the user information invoked through the input module.
The intelligent terminal according to the present invention may be a computer, a mobile phone, and other electronic devices.
The index table according to the present invention characterizes the corresponding relation between different index numbers and common user information types, wherein the common user information types may be name, address, telephone, mobile phone No., ID Card No., passport No., bank card No., unit name, or the like; the index numbers may be numeral, lowercase, capital letter, roman numerals, or the like, may also be a combination of the different types of symbols above, and may also be above symbols added with bracket, colon, comma, circle, underscore, or the like, wherein different information types are corresponding to each index number one to one, for example, when a numeral added with a colon is used as the index number, then the form of the index table may be 1: name, 2: address, and 3: telephone; and the common user information types in the index table and the corresponding index numbers thereof may further be added, amended, or deleted.
The second processing module according to the present invention generates the index number list according to the user information type needed to be acquired and with reference to the index table stored by the second storage module. It is provided that the user information type needed to be acquired by the information acquisition end comprises name, address, and telephone, and meanwhile, the index table stored by the second storage module is 1. name, 2. address, and 3. telephone, then the index number list generated by the second processing module is 1:2:3:, and after the intelligent terminal receives the index number list, with reference to the index table stored by the first storage module which is 1. name, 2. address, and 3. telephone; it can be determined that the user information type needed to be acquired by the information acquisition end is name, address, and telephone. In this way, only less information is needed to be transmitted between the intelligent terminal and the information acquisition end, which is convenient to process information, does not occupy the space, and is beneficial for applying an information carrier such as the two-dimensional code.
The information acquisition end according to the present invention may transmit the index number list generated to the intelligent terminal through second communication module. Further, the intelligent terminal receives the index number list transmitted by the information acquisition end through the first communication module. Moreover, the index number list generated by the second processing module may also be converted into the corresponding two-dimensional code through the two-dimension code generation module II, and the corresponding two-dimensional code is outputted through the two-dimensional code output module II. Further, the intelligent terminal recognizes the two-dimensional code outputted by the two-dimensional code output module II through the two-dimensional code recognition module I, and parses out the corresponding index number list.
After the intelligent terminal according to the present invention receives the index number list, the first processing module determines the user information type needed by the information acquisition end with reference to the index table stored by the first storage module, and controls the display module to display the information of the user information type needed by the information acquisition end. Further, the input module may input the corresponding user information according to the information of the user information type displayed by the display module.

Preferably, the input module may also correspondingly input a plurality of user information corresponding to each user information type, for example, titles including dean, professor, and doctoral supervisor, wherein the user information type title is corresponding to such three user information including dean, professor, and doctoral supervisor. Further, the first storage module may store the plurality of user information corresponding to the user information types thereof in advance. When the first processing module invokes the plurality of user information under a certain user information type from the first storage module, the user may select effective user information from the plurality of user information through the input module. In order to reduce the risk of leaking the important user information in use, preferably, each user information may be differentiated through adding an identifier that may be an index number, so that the original user information does not need to be displayed when the user make a selection, and only the identifiers of different user information are needed to be displayed, so as to effectively guarantee the user information security.
The first processing module according to the present invention establishes a corresponding relation between each index number extracted and the user information inputted by the input module, and forms integrated user information through an integration operation. The integration operation may specifically be: inserting a separator in a rear end of the user information corresponding to each index number, and then combining each index number with the user information respectively corresponding to each index number, to form the integrated user information; for example, the index numbers are respectively 1: (representing the information type name), 2: (representing the information type telephone), and 3: (representing the information type address); the user information inputted by the input module respectively corresponding to the name, telephone, and address are Xia Yong, 13912345678, No. 1, Zhongguancun Street, Beijing; then the integrated user information is formed as:
1: Xia Yong, 2: 13912345678, and 3: No. 1, Zhongguancun Street, Beijing, wherein, “;” is the separator, and the integrated user information is a piece of information integrated together.
The user information respectively corresponding to the user information type needed to be acquired is obtained by the second processing module through an extraction operation on the integrated user information, wherein the extraction operation is: looking up the separators in the integrated user information, separating the information at the front end of each of the separator from the integrated user information in sequence, and acquiring the user information needed according to the user information type characterized by the index number in the information separated. As the integrated user information described above, the separators thereinto are looked up, and the information at the front end of each of the separator is separated from the integrated user information in sequence, and then the three parts including 1: Xia Yong, 2: 13912345678, and 3: No. 1, Zhongguancun Street, Beijing, are respectively obtained, then, it is determined that the name is Xia Yong, the telephone is 13912345678, and the address is No. 1, Zhongguancun Street, Beijing according to the information types respectively represented by the index numbers 1:, 2:, and 3:.
