Based on the above mobile terminal hardware structure and communication network system, the present invention provides various embodiments of the method.

First embodiment

The first embodiment of the invention provides a method for acquiring a two-dimensional code, which can be applied to a terminal with a function of acquiring the two-dimensional code.

Here, the terminal described above may be a fixed terminal having a display screen, or may be a mobile terminal having a display screen.

The above-mentioned fixed terminal may be a computer, and the above-mentioned mobile terminal includes but is not limited to a mobile phone, a notebook computer, a camera, a PDA, a PAD, a PMP, a navigation device, and the like. The terminal can be connected to the internet, wherein the connection can be made through a mobile internet network provided by an operator, or through accessing a wireless access point.

Here, if the mobile terminal has an operating system, the operating system may be UNIX, Linux, Windows, Android (Android), Windows Phone, or the like.

The type, shape, size, and the like of the display screen on the terminal are not limited, and the display screen on the terminal may be a liquid crystal display screen, for example.

In the first embodiment of the present invention, the display screen described above is used to provide a human-computer interaction interface for a user.

Fig. 3 is a flowchart of a first embodiment of a method for acquiring a two-dimensional code in the embodiment of the present invention, as shown in fig. 3, the method includes:

step 301: and when the terminal receives the two-dimension code acquisition instruction, acquiring the position information of the terminal.

Illustratively, when the payer terminal executes the transfer operation, the transfer operation interface has a touch key for indicating the operation of scanning the two-dimensional code, such as: and scanning character indication or image indication, and clicking the touch key by a user to start to execute the operation of acquiring the two-dimensional code.

Illustratively, acquiring the location information of itself includes: the terminal starts a Global Positioning System (GPS) to perform positioning, so as to obtain its own location information, where the location information at least includes latitude information and longitude information of the location of the terminal.

Step 302: at least one secure two-dimensional code associated with the location information is obtained.

Here, the associated secure two-dimensional code refers to a secure two-dimensional code whose separation distance from the position where the payer terminal is located is smaller than a separation threshold, for example, the value range of the separation threshold may be an integer smaller than 100 m.

In practical implementation, the steps may specifically include the following:

step A1: determining the area where the terminal is located according to the position information; illustratively, a circular area with a radius of 10m is taken as the area where the terminal is located, with the location of the terminal as the center.

Step A2: determining all transfer two-dimensional codes of which the terminal can execute transfer operation in the area; here, the transfer two-dimensional code of the transfer operation executable by the terminal refers to a two-dimensional code of the transfer operation executable after being recognized by the current transfer application, for example: when the transfer application A can only identify the transfer two-dimensional code generated by the transfer application A and perform transfer operation, all transfer two-dimensional codes of which the terminal can perform transfer operation only contain the transfer two-dimensional code generated by the transfer application A and do not contain two-dimensional codes generated by other transfer applications.

Step A3: and screening all determined transfer two-dimensional codes to obtain at least one safe two-dimensional code. For example, the method for screening all determined transfer two-dimensional codes may be as follows: judging whether the determined two-dimensional code is subjected to real-name authentication in the transfer application or not, and determining the two-dimensional code subjected to real-name authentication as a safe two-dimensional code; otherwise, determining the two-dimension code as a non-safe two-dimension code, and recommending the safe two-dimension code to the user.

Illustratively, the transfer two-dimensional code includes at least one of: the account transfer two-dimensional codes of all shops in the area and the account transfer two-dimensional codes of all terminals executing account transfer operation in the area.

When the terminal needs to perform the transfer operation by scanning the two-dimensional code, the two-dimensional code information is acquired firstly, the transfer object is determined by identifying the acquired two-dimensional code information, and finally the specified amount is transferred out. Therefore, the separation distance between the scanned two-dimensional code and the terminal is smaller than the maximum scanning distance, or the separation distance is smaller than the separation threshold, so that the two-dimensional code to be scanned is necessarily located in the area where the terminal is located.

For example, the method for the terminal to obtain the at least one secure two-dimensional code may be: the terminal obtains at least one safe two-dimensional code through a mobile operator network, a WIFI wireless network or Bluetooth.

Specifically, the terminal firstly carries out terminal positioning according to a connected WIFI wireless network and obtains at least one safe two-dimensional code; when the WIFI wireless network connection fails, obtaining the WIFI wireless network connection through Bluetooth; and when the WIFI wireless network and the Bluetooth are failed to be connected, the mobile operator network is used finally.

Here, the terminal can actively connect with the WIFI wireless network in the area when reaching the current area, when the network signal of the detection side is poor, the Bluetooth connection or the mobile operator network connection is directly carried out when the two-dimensional code scanning operation is executed, and the time waste caused by the fact that the WIFI wireless network connection is tried is avoided.

Step 303: and sequencing at least one safe two-dimensional code according to a preset sequencing strategy to generate a two-dimensional code recommendation list.

The preset ordering strategy comprises the following steps: and sequencing according to the spacing distance between the terminal and each safe two-dimensional code.

In practical implementation, the distance between the terminal and each secure two-dimensional code may be the distance between the terminal and a store in the area where the secure two-dimensional code belongs, or the distance between the terminal and a terminal in the area where the secure two-dimensional code belongs.

Illustratively, the area range of the terminal comprises two shops, the terminal acquires the transfer two-dimensional codes of the two shops and sorts the transfer two-dimensional codes according to the spacing distance between the terminal and the shop to which each transfer two-dimensional code belongs, and the transfer two-dimensional codes with the smaller spacing distance are positioned at the front end of the list.

It is understood that when the terminal is ready to perform the operation of scanning the two-dimensional code, the transfer two-dimensional code to be scanned from the payee will be spaced from the payer terminal by a distance smaller than the maximum scanning distance, for example, the maximum scanning distance is 1m, and the smaller the spacing distance, the more likely the transfer two-dimensional code to be scanned from the terminal will be. Therefore, in practical implementation, the secure two-dimensional codes can be sorted according to the spacing distance between the terminal and the two-dimensional codes, and the two-dimensional codes are arranged in a front order as the spacing distance is smaller.

Another optional preset ordering policy may include:

Here, when the influence of the interval distance and the historical scanning times on the arrangement sequence of the two-dimensional codes is comprehensively considered, corresponding weight values can be respectively set according to the influence programs of the interval distance and the historical scanning times, and the most probable transfer two-dimensional codes, namely the two-dimensional codes arranged at the first position in the two-dimensional code recommendation list, are determined after weight operation.

Illustratively, a first weight value is set to be f1, and a second weight value is set to be f 2;

sequencing according to the spacing distance between the terminal and each safe two-dimensional code, and determining the arrangement serial number Si of the spacing distance corresponding to each safe two-dimensional code; si is an arrangement serial number of the interval distance corresponding to the ith safe two-dimensional code, and i is a positive integer;

sequencing the historical scanning times of each safe two-dimensional code according to the terminal, and determining the arrangement serial number Ni of the historical scanning times corresponding to each safe two-dimensional code; ni is the arrangement serial number of the historical scanning times corresponding to the ith safe two-dimensional code;

carrying out weighted summation on each safe two-dimensional code according to the first weight value and the second weight value, wherein the weighted summation formula is (f1 multiplied by Ni + f2 multiplied by Si)/2, and Pi is the weighted summation result of each safe two-dimensional code;

and sequencing the safe two-dimensional codes according to the value Pi of the weighted sum of each safe two-dimensional code to generate a two-dimensional code recommendation list.

Step 304: and determining the transfer two-dimensional codes according to the arrangement sequence of the two-dimensional codes in the two-dimensional code recommendation list.

Here, the transfer two-dimensional code is used to cause the terminal to perform a transfer operation according to the transfer two-dimensional code.

The method can further comprise the following steps: and displaying the two-dimension codes in the recommendation list.

Illustratively, the two-dimensional codes are sequentially and independently displayed on a terminal from top to bottom according to the arrangement sequence of the two-dimensional codes in a two-dimensional code recommendation list, and when the transfer two-dimensional codes are determined, the two-dimensional codes are stopped to be displayed; or all the two-dimension codes are displayed on the terminal from top to bottom according to the arrangement sequence of the two-dimension codes in the two-dimension code recommendation list.

Specifically, when the two-dimensional codes are sequentially and independently displayed and when the user determines that the two-dimensional codes are transferred, the two-dimensional codes after the arrangement sequence are stopped being displayed.

In practical implementation, the two-dimensional code recommendation list may include: payee information corresponding to the two-dimensional code; and determining the transfer two-dimensional code according to the arrangement sequence of the two-dimensional codes in the two-dimensional code recommendation list and payee information corresponding to the two-dimensional codes. Here, not only can show the safe two-dimensional code that obtains according to the array order of two-dimensional code, still can show the payee information that each two-dimensional code corresponds simultaneously, make the payer user can more accurate definite account transfer two-dimensional code, avoid the mistake to transfer accounts for other people.

For example, the payee information corresponding to the two-dimensional code may be: the user name, user avatar, or other identifying information of the transfer object. For example: when the terminal displays the two-dimension code recommendation list, only payee information corresponding to each two-dimension code can be displayed, or corresponding payee information is displayed below the image information when the image information of the two-dimension codes is displayed.

Fig. 4 is an interaction schematic diagram of a terminal in a first embodiment of the present invention, and as shown in fig. 4, when the terminal receives a two-dimensional code acquisition instruction, a display interface displays a two-dimensional code recommendation list, where the two-dimensional code recommendation list includes: the 1 st two-dimensional code and the corresponding user name 1, the user name 2 corresponding to the 2 nd two-dimensional code, and the user name 3 corresponding to the 3 rd two-dimensional code. The 1 st two-dimensional code is the two-dimensional code closest to the terminal and most probably the transfer two-dimensional code to be acquired by the terminal, a user finally confirms whether the 1 st two-dimensional code is the transfer two-dimensional code or not through displayed payee information, namely a user name 1, if so, the user clicks the 1 st two-dimensional code to input a transfer confirmation instruction to the terminal, and the terminal executes transfer operation after acquiring the transfer confirmation instruction; otherwise, the user checks whether the user name 2 of the 2 nd two-dimensional code and the user name 3 of the 3 rd two-dimensional code are transfer two-dimensional codes in sequence, and the operation mode of the 2 nd two-dimensional code and the 3 rd two-dimensional code is the same as that of the 1 st two-dimensional code. And when the transfer two-dimensional codes do not exist in the two-dimensional code recommendation list, clicking the 'update list' to acquire a new two-dimensional code recommendation list, or clicking 'scanning and scanning' to scan the transfer two-dimensional code information through a camera.

In order to further embody the object of the present invention, the above-mentioned scheme is further exemplified on the basis of the first embodiment of the present invention.

step 501: and the terminal receives the two-dimension code acquisition instruction.

Step 503: and determining the area of the terminal according to the current position information of the terminal.

Step 504: and acquiring at least one safe two-dimensional code in the area range of the terminal.

Exemplarily, taking the position of the terminal as a center, taking a circular area with the radius of 10m as an area where the terminal is located, and searching for the transfer two-dimensional codes of all terminals executing transfer operation in the area;

and acquiring the transfer two-dimensional codes of all terminals executing transfer operation.

It should be noted that when the transfer is performed to the other party by scanning the transfer two-dimensional code of the other party between the user and the user, the account receiver opens the two-dimensional code image of the user, and the user of the account receiver clicks the two-dimensional code scanning operation to acquire the two-dimensional code image of the account receiver.

Specifically, the obtaining of one secure two-dimensional code in the area range where the terminal is located may include the following steps:

step B1: the first terminal searches all second terminals which are executing the transfer operation in the area where the first terminal is located; the first terminal is a transfer party terminal, and the second terminal is an account receiving party terminal;

step B2: the method comprises the steps that a first terminal sends a request for obtaining a transfer two-dimensional code to a second terminal;

step B3: the second terminal sends the self account-receiving two-dimensional code to the first terminal;

step B4: the first terminal detects whether the transfer two-dimensional code sent by the second terminal is safe or not; and if the safe first terminal determines that the transfer two-dimensional code is the safe two-dimensional code, otherwise, the first terminal refuses to receive the transfer two-dimensional code.

And B1-B4 are carried out by the first terminal on all second terminals which are executing the transfer operation in the area, so that all the safe two-dimensional codes in the area where the first terminal is located are obtained.

Step 508: and the terminal scans the transfer two-dimensional code and executes transfer operation.

Fig. 6A, 6B, and 6C are interaction diagrams of the terminal in the second embodiment, respectively, and fig. 6A shows that a user clicks a "scan" key on the terminal to enable the terminal to receive a two-dimensional code acquisition instruction.

Fig. 6B shows that, after the two-dimensional code acquisition instruction is received by the terminal, a two-dimensional code recommendation list is displayed, where the two-dimensional code recommendation list includes: the user confirms the transfer two-dimensional code through the displayed user name 1 and the user name 2. If the two-dimension code recommendation list contains the transfer two-dimension code, the user clicks the corresponding two-dimension code image to input a transfer confirmation instruction, and the terminal is instructed to execute transfer operation; and if not, clicking the 'update list' to acquire a new two-dimension code recommendation list, or clicking a 'scanning and scanning' button to scan the transfer two-dimension code information through a camera.

Third embodiment

To further illustrate the object of the present invention, the first embodiment of the present invention is further exemplified.

Fig. 7 is a flowchart of a third embodiment of a method for acquiring a two-dimensional code in the embodiment of the present invention, and as shown in fig. 7, the flowchart includes:

step 701: and when the terminal receives the two-dimension code acquisition instruction, acquiring the current position information of the terminal.

Step 702: and determining the area of the terminal according to the current position information of the terminal.

Step 703: and determining all transfer two-dimensional codes of the transfer operation executable by the terminal in the area.

Step 704: and screening all determined transfer two-dimensional codes to obtain at least one safe two-dimensional code.

Exemplarily, searching all shops in a region by taking the position of a terminal as a center and taking a circular region with the radius of 10m as the region of the terminal; the transfer two-dimensional codes of the shops can be stored in the server side in advance, and the user terminal obtains the transfer two-dimensional codes of the corresponding shops from the server side.

Determining transfer two-dimensional codes of all shops in the area; here, the two-dimensional code of the store may be regarded as a two-dimensional code that passes security authentication, that is, a secure two-dimensional code that passes filtering.

Step 705: and sequencing all the obtained safe two-dimension codes according to a preset sequencing strategy to generate a two-dimension code recommendation list.

Illustratively, the preset ordering policy includes: setting a corresponding first weight value for the distance between the terminal and each safe two-dimensional code; setting a corresponding second weighted value for the historical scanning times of each safe two-dimensional code; carrying out weighted summation on each safe two-dimensional code according to the first weight value and the second weight value; and sequencing all the safe two-dimensional codes according to the weighted sum result to generate a two-dimensional code recommendation list.

Specifically, sequencing is carried out according to the spacing distance between the terminal and each safe two-dimensional code, and the arrangement serial number Si of the spacing distance corresponding to each safe two-dimensional code is determined; si is the arrangement sequence of the spacing distances corresponding to the ith safe two-dimensional code, and i is a positive integer;

carrying out weighted summation on each safe two-dimensional code according to a first weight value and a second weight value, wherein the weighted summation formula is Pi ═ f1 × Ni + f2 × Si)/2, wherein Pi is the weighted summation result of each safe two-dimensional code, f1 is the first weight value, and f2 is the second weight value;

and sequencing all the obtained weighted sum values Pi according to the order of arrival from the beginning to generate a two-dimensional code recommendation list.

Illustratively, acquiring 3 secure two-dimensional codes includes: the two-dimensional code comprises a two-dimensional code 1, a two-dimensional code 2 and a two-dimensional code 3;

table 1 shows an arrangement order of the weighted sum results of the secure two-dimensional codes, where the arrangement order obtained according to the distance intervals in table 1 is: the two-dimensional code comprises a two-dimensional code 2, a two-dimensional code 1 and a two-dimensional code 3; the arrangement sequence obtained by sequencing according to the historical scanning times is as follows: the two-dimensional code comprises a two-dimensional code 1, a two-dimensional code 2 and a two-dimensional code 3; obtaining a weighted summation result Pi of each safety two-dimensional code according to a weighted summation formula Pi ═ f1 × Ni + f2 × Si)/2, wherein a first weight value f1 is equal to 0.6, a second weight value f2 is equal to 0.4, Ni is an arrangement serial number of the historical scanning times of the ith safety two-dimensional code, and Si is an arrangement serial number of the interval distance of the ith safety two-dimensional code; the weighted summation result of each secure two-dimensional code is obtained as follows: 0.8, 0.9, 1.3; sorting the weighted summation results from small to large, wherein the obtained sorting order is as follows: two-dimensional code 1, two-dimensional code 2 and two-dimensional code 3

TABLE 1

Permutation number	Sorting by separation distance	Sorting by number of scans	Sorting by weighted sum result
				1	Two-dimensional code 2	Two-dimensional code 1	Two-dimensional code 1
2	Two-dimensional code 1	Two-dimensional code 3	Two-dimensional code 2
				3	Two-dimensional code 3	Two-dimensional code 2	Two-dimensional code 3

It can be understood that when the terminals are sorted by the spacing distance only, the situation of inaccurate calculation is avoided, and the sorting accuracy can be increased by considering the historical operation times of the two-dimensional code. For example, two shops with close distances, a first shop is frequently visited by a user, a second shop is rarely visited by the user or never visited by the user, if the two-dimensional code recommendation list is generated only by the separation distance, when the terminal detects the separation distance from the surrounding shops, the measured separation distance is probably that the second shop is smaller than the first shop, so that the accuracy of the two-dimensional code recommendation list pushed to the user is not high, and a redundant screening process is brought to the user. By carrying out weight operation on the interval distance and the historical scanning times, influence factors are considered in multiple directions, and the accuracy of obtaining the two-dimensional code can be improved.

Step 706: judging whether the two-dimension code recommendation list contains a transfer two-dimension code, if so, executing step 707; if not, step 708 is performed.

For example, the user determines whether the two-dimensional code recommendation list includes the transfer two-dimensional codes according to payee information corresponding to each transfer two-dimensional code, where the corresponding payee information may be set as the name of the store to which the user belongs.

Step 707: and determining the transfer two-dimensional code from the two-dimensional code recommendation list, and executing transfer operation according to the transfer two-dimensional code.

In practical application, a user can search the transfer two-dimensional code from the first position in the two-dimensional code recommendation list according to the information of the terminal to which the two-dimensional code belongs, and after the transfer two-dimensional code is determined, the user clicks a two-dimensional code image to input a transfer confirmation instruction so as to indicate the terminal to execute transfer operation.

Step 708: and the terminal scans the transfer two-dimensional code and executes transfer operation.

By adopting the technical scheme, at least one safe two-dimensional code is pushed to the terminal according to the area where the terminal is located, so that the terminal directly selects the two-dimensional code for executing the account transfer operation from the safe two-dimensional code to execute the account transfer operation, and account transfer two-dimensional code information can be acquired without scanning the two-dimensional code operation.
