Detailed Description
In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only partial embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a first flow chart of an embodiment of a two-dimensional code encryption method according to the present application. The two-dimensional code encryption method comprises the following steps:
s101: and when the mobile terminal starts payment, displaying a two-dimensional code picture for payment.
Specifically, the two-dimensional code image can be used for online payment or offline payment, consumption, transfer, pre-authorization and the like, and meanwhile, the two-dimensional code image can also comprise limit information of transaction.
Wherein, the two-dimensional code picture can include two kinds: the payment system comprises a static two-dimensional code picture and a dynamic two-dimensional code picture, wherein the static two-dimensional code picture is generated based on a payment account, the effective time is long, such as three months or one year, and the static two-dimensional code picture can be used in an online environment for many times; the dynamic two-dimensional code picture is generated based on the static two-dimensional code picture, the effective time is short, such as 1 minute or 30 seconds, and the dynamic two-dimensional code picture can be used only once in an online environment.
S102: and when the preset encryption condition is met, displaying the auxiliary picture on the two-dimensional code picture.
The auxiliary picture is used for encrypting the two-dimensional code picture.
Specifically, the preset encryption condition may include receiving an encryption instruction, a preset user encryption gesture, or an operation state of the mobile terminal within a certain time period.
The encryption instruction can be triggered by pressing an special key (for example, a Home key) on the terminal device by the user, or can be triggered by a specific operation (for example, a click operation or a sliding operation) input by the user on the mobile terminal or a key combination (in the form of a combination of user-defined setting keys) on the virtual keyboard. For example, the user may trigger the encryption command by clicking an "encrypt" button in the mobile terminal.
The preset user encryption gesture can be at least one of clicking the two-dimensional code picture, sliding the two-dimensional code picture, long-pressing the two-dimensional code picture, turning the two-dimensional code picture, clicking an encryption button or sliding a screen.
The operation state of the mobile terminal within a certain period of time may be no operation by the user within 5 seconds.
It should be noted that the mobile terminal may encrypt the two-dimensional code picture when the preset encryption condition is met, for example, after receiving the encryption instruction, the mobile terminal may display an auxiliary picture to the user, where the auxiliary picture may cover the two-dimensional code picture or directly replace the two-dimensional code picture.
The auxiliary picture may be an opaque picture or a partially transparent picture preset by a user, for example, a random picture or a randomly generated color picture in an album, or an auxiliary picture obtained by performing picture blurring on a two-dimensional code picture, or an auxiliary picture obtained by encrypting a two-dimensional code picture. The encryption process may be: and embedding encryption information in payment information contained in the two-dimensional code picture, and regenerating the two-dimensional code picture containing the encryption information and the payment information. After the user inputs the encryption instruction through the designated operation, the mobile terminal can encrypt the two-dimensional code picture according to the default encryption mode and the encryption key to obtain the auxiliary picture. After the auxiliary picture is displayed, even if the payee or lawless person scans the auxiliary picture, the deduction cannot be realized.
S103: and when the preset decryption condition is met, the display of the auxiliary picture is cancelled so as to display the two-dimensional code picture.
Specifically, the preset decryption condition may be a decryption instruction received, a preset user decryption gesture, or an operation state of the mobile terminal within a time period.
The decryption instruction can be triggered by pressing an ad hoc key (e.g., Home key) on the terminal device by the user, or can be triggered by a specific operation (e.g., a click operation or a sliding operation) input by the user on the mobile terminal or a key combination (in the form of a combination of user-defined setting keys) on the virtual keyboard. For example, the user may trigger the decryption instruction by clicking a "decrypt" button in the mobile terminal.
The preset user decryption gesture may be at least one of clicking the auxiliary picture, sliding the auxiliary picture, long-pressing the auxiliary picture, flipping the auxiliary picture, clicking a decryption button, or sliding the screen.
It should be noted that the mobile terminal may cancel displaying the auxiliary picture according to the received decryption instruction, for example, after receiving the encryption instruction, the mobile terminal may cancel displaying the auxiliary picture and display the two-dimensional code picture in S101 to the user.
Be different from prior art's condition, this embodiment is when satisfying to predetermine the encryption condition, show the supplementary picture on the two-dimensional code picture that is used for paying, in order to realize carrying out encryption processing to the two-dimensional code picture, and can be when satisfying to predetermine the decryption condition, cancel the supplementary picture of demonstration, in order to show the two-dimensional code picture, and then the payee only needs to sweep the payment two-dimensional code that the payer shows on mobile terminal, can realize paying, at this in-process, the user can encrypt the two-dimensional code picture, thereby avoid being swept the code and steal money and property by lawless persons in the period of waiting for the payee to scan the payment two-dimensional code, can improve the security of mobile payment, improve user's payment experience.
In one embodiment, step S102 includes the steps of: and covering the auxiliary picture on the two-dimensional code picture. And the auxiliary picture is covered on the two-dimensional code picture with a preset transparency.
Specifically, when the preset encryption condition is met, an auxiliary picture with the same shape as the two-dimensional code picture is generated, and then the auxiliary picture is covered on the two-dimensional code picture. The auxiliary picture may be set to be a picture with any transparency value greater than 0, where a transparency value of 0 is fully transparent and a transparency value of 1 is non-transparent. That is to say, in the embodiment of the present application, the transparency value of the auxiliary picture may be set to be a picture having any transparency value between full transparency and non-transparency, or the transparency value of the auxiliary picture may be set to be 1, that is, no transparency, and a specific transparency value may be set by a user, which is not specifically limited in the embodiment of the present application. For example, a mask having a color value of #000000 or # FFFFFF and a transparency value greater than 0 may be overlaid on the two-dimensional code image.
Through the shade that covers a predetermined transparency in two-dimensional code picture upper side, cover the two-dimensional code picture, and then avoid being swept the sign indicating number and stealing money by lawbreaker in the period of waiting for payee to scan the payment two-dimensional code, consequently can improve the security of mobile payment, improve user's payment experience.
Referring to fig. 2, fig. 2 is a second flow chart of an embodiment of a two-dimensional code encryption method according to the present application. Before step S102, the method further comprises the steps of:
s201: the secure payment levels and the payment information corresponding to each secure payment level are predefined.
The payment information comprises at least one of payment amount and payment mode.
Specifically, the user may pre-define the secure payment level and the payment information corresponding to each secure payment level according to the self-payment habit, where the payment information may include at least one of payment amount, payment times, and payment method. For example, the user divides the security payment level into three types of high, medium, and low, and when the payment amount is used as the payment information, the payment amount of the high security payment level may be set to 5000 yuan or more, the payment amount of the medium security payment level may be set to 300 yuan to 5000 yuan, and the payment amount of the low security payment level may be set to less than 300 yuan. Or, taking the payment treasures as an example, when the payment method is used as the payment information, the payment method of the high security payment level may be set as balance treasures payment, the payment method of the medium security payment level may be set as balance payment, and the payment method of the low security payment level may be set as beibei payment. In other embodiments, a different payment amount or payment method may be set, which is not limited herein.
S202: a predetermined transparency is set for each secure payment level.
Specifically, the transparency of the corresponding auxiliary picture may be set for three security payment levels, namely, high, medium, and low. It should be noted that the higher the security payment level is, the closer the transparency value of the auxiliary picture is to 1, for example, the transparency value corresponding to the high security payment level may be set to 1, that is, no transparency; setting the transparency value corresponding to the middle security payment level to be 0.8; the transparency value for a low security payment level is set to 0.5.
Through the method, the transparency value corresponding to the safety payment level is determined according to the corresponding relation between the preset safety payment level and the payment amount or the payment mode, the auxiliary picture is processed according to the transparency value, the transparency value of the auxiliary picture is correspondingly changed according to the safety payment level corresponding to the payment amount or the payment mode, and the convenience of user operation can be improved while the payment safety is guaranteed.
In one embodiment, step S102 includes the steps of: and carrying out picture fuzzy processing on the two-dimensional code picture to obtain an auxiliary picture, and displaying the auxiliary picture.
Specifically, the image blurring processing may adopt a common image gaussian blurring processing, wherein a principle of the gaussian blurring processing is as follows: the term "blurring" is understood to mean that the pixel value of each pixel is the average of the pixel values of the surrounding pixels, as shown in fig. 3 and 4, where fig. 3 is a schematic diagram before gaussian blurring and fig. 4 is a schematic diagram after gaussian blurring. "2" in fig. 3 is the pixel value of the middle pixel point, the pixel values of the peripheral pixel points are all 1, after gaussian blurring processing, the average value of the pixel values of the peripheral pixel points taken by the pixel value of the middle pixel point in fig. 4 becomes 1, and in terms of the value, this is smoothing processing, on the image, it is equivalent to generating a blurring effect, and the middle pixel point loses details; obviously, when calculating the average value of the pixel values of the middle pixel points, the larger the value range (i.e., the value of the number of the peripheral pixel points), the stronger the blurring effect.
When the step is executed, the current display interface is a payment interface, the image of the current display interface is the two-dimensional code picture corresponding to the payment interface, the two-dimensional code picture is subjected to Gaussian blur processing to generate a two-dimensional code picture with a blur effect (the two-dimensional code picture with the blur effect is an auxiliary picture), and the auxiliary picture is displayed on the payment interface so that a user can see the two-dimensional code picture with the blur effect.
Further, considering that the algorithm of the gaussian blur processing is complex, and the complexity of the calculation is related to the image resolution and the blur radius, in order to reduce the amount of the gaussian blur operation and increase the speed of the blur processing, generally, an original two-dimensional code image with a higher resolution is reduced to an intermediate two-dimensional code image with a lower resolution, then the gaussian blur processing is performed on the intermediate two-dimensional code image with the lower resolution, and the blurred image is enlarged to the size of the original two-dimensional code image, so that the obtained blurred image still visually approaches the blur effect of directly performing the gaussian blur processing on the original two-dimensional code image.
Through the Gaussian blur processing two-dimensional code picture, an auxiliary picture does not need to be stored in the mobile terminal, and the storage consumption of the mobile terminal is reduced.
Referring to fig. 5, fig. 5 is a third flow chart of an embodiment of the two-dimensional code encryption method according to the present application. In an embodiment, before step S102, the method further includes the steps of:
s301: and inputting preset fingerprint information into the mobile terminal, and associating the preset fingerprint information with the encryption instruction.
Specifically, a first association triggering instruction may be input to the mobile terminal to trigger the mobile terminal to enter a fingerprint information setting mode. And after entering a fingerprint information setting mode, starting to input preset fingerprint information, and associating the preset fingerprint information with the encryption instruction.
S302: the method comprises the steps of collecting first fingerprint information input by a user, and judging whether the first fingerprint information is matched with preset fingerprint information.
Specifically, first fingerprint information input by a user is collected through the fingerprint identification module, and the first fingerprint information is compared with preset fingerprint information.
S303: and if the matching is successful, determining that the encryption instruction input by the user meets the preset encryption condition.
Specifically, the preset encryption condition is an encryption instruction input by the user, when the first fingerprint information is successfully matched with the preset fingerprint information, the encryption instruction of the mobile terminal corresponding to the preset fingerprint information is searched through the preset configuration table to determine that the encryption instruction input by the user is satisfied, and at this time, the step S102 is performed.
When detecting that the user continuously inputs the first fingerprint information, continuously displaying an auxiliary picture on the two-dimensional code picture; and when the condition that the user stops inputting the first fingerprint information is detected, the preset decryption condition is met, the display of the auxiliary picture is cancelled, and the two-dimensional code picture is displayed for the user.
Further, before step S103, the method may further include: and inputting preset decryption fingerprint information into the mobile terminal, and associating the preset decryption fingerprint information with the decryption instruction. Specifically, a first association triggering instruction may be input to the mobile terminal to trigger the mobile terminal to enter a fingerprint information setting mode. And after entering a fingerprint information setting mode, starting to input preset decryption fingerprint information, and associating the preset decryption fingerprint information with a decryption instruction.
And acquiring second fingerprint information input by the user, and judging whether the second fingerprint information is matched with the preset decryption fingerprint information. Specifically, second fingerprint information input by a user is collected through the fingerprint identification module, and the second fingerprint information is compared with preset decryption fingerprint information.
And if the matching is successful, determining that the user inputs a decryption instruction and meeting the preset decryption condition. Specifically, when the second fingerprint information is successfully matched with the preset decryption fingerprint information, the decryption instruction of the mobile terminal corresponding to the preset decryption fingerprint information is searched through the preset configuration table to determine that the user inputs the decryption instruction, and at this time, the preset decryption condition is met and the step S103 is performed.
Through the method, the operation steps of sending the encryption instruction by the user can be simplified, and when the first fingerprint information input by the user is matched with the preset fingerprint information, the encryption instruction can be sent, so that the mobile terminal receives the encryption instruction, responds to the encryption instruction, and displays the auxiliary picture on the two-dimensional code picture.
Referring to fig. 6, fig. 6 is a fourth flowchart illustrating a two-dimensional code encryption method according to an embodiment of the present application. In an embodiment, before step S102, the method further includes the steps of:
s401: a preset duration is preset.
Specifically, the preset time period is less than 1 minute. Since the two-dimensional code picture may be a dynamic two-dimensional code picture, and the valid time of the two-dimensional code picture is usually 1 minute or 30 seconds, the preset time may be set to be less than 1 minute or less than 30 seconds, for example, the preset time is 3 seconds or 5 seconds, corresponding to the valid time.
S402: and when the two-dimensional code picture is displayed, timing is started.
Specifically, the mobile terminal can detect whether a two-dimensional code picture is displayed at present, and starts timing when the two-dimensional code picture is detected to be displayed.
S403: and when the timing time reaches the preset time length, the preset encryption condition is met.
Specifically, for example, when the timing time reaches a preset duration of 3 seconds, a preset encryption condition is met, and the auxiliary picture is displayed on the two-dimensional code picture.
Further, before step S103, the method may further include:
and when the auxiliary picture is displayed, timing is started. Specifically, the mobile terminal can detect whether an auxiliary picture is currently displayed, and when the auxiliary picture is detected to be displayed, timing is started.
