Description

Verification information display method and mobile terminal

Technical Field

The invention relates to the field of terminals, in particular to a verification information display method and a mobile terminal.

Background

Verification code (CAPTCHA) is an abbreviation for Turing test that fully automatically distinguishes Computers from Humans, a common fully Automated program that distinguishes users as Computers or Humans. The method can be used for preventing malicious password cracking, ticket swiping, forum water filling, and the like, and a certain hacker makes continuous login attempts on a certain specific registered user in a specific program brute force cracking mode.

Currently, a generic verification code, such as: the verification code based on the limited picture library can be automatically identified after sufficient samples are subjected to machine learning; for another example, a verification code picture added with noise and interference can also be recognized by an increasingly mature Optical Character Recognition technology (OCR).

Therefore, a display scheme of authentication information such as an authentication code that can prevent automatic computer recognition is required.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. 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 invention.

As stated in the background section, in order to allow a user to visually view authentication information (taking an authentication code as an example), the prior art requires that the authentication code be presented in clear. Regardless of how the prior art adds background noise, interference and the like to the picture carrying the verification code, the computer can identify the verification code therein by the increasingly sophisticated OCR technology. Further, the problems of ticket robbery and ticket purchase of the machine, violent password cracking and the like can occur.

Based on the above, the invention provides a verification information display method, which comprises the steps of adding shading on target verification information to generate a target verification image carrying invisible target verification information; and displaying the target authentication image to the user together with the pre-constructed first image, since the first image is in a role of acting as a "decryption card", the user can make the target authentication information visible by overlaying the first image on the target authentication image.

The verification code may be a character verification code, an image verification code, or the like.

The following describes an exemplary application scenario of the present invention with reference to fig. 1a and 1 b:

and based on the user operation, the terminal jumps to an interface for displaying verification information and waiting for inputting the verification information by the user.

Referring to fig. 1a, the initial interface may include: the suspended frame 11, the verification image 12 and the verification code input frame 13, the verification image 12 carries verification information (taking the verification code as an example), but because the lines of the verification code are completely covered or partially covered by the preset shading, the user cannot clearly know the specific content of the verification code. Moreover, because the lines of the verification code and the preset shading are interwoven together, the lines and the preset shading are integrated on the levels of gray values, boundaries and the like, the possibility of character segmentation is reduced, and the difficulty of computer identification is further increased.

Referring to fig. 1b, the user drags the suspension frame 11 to cover the verification image 12, and since the suspension frame 11 is embedded with the semitransparent shading picture, and the semitransparent shading picture carries the decrypted shading corresponding to the preset shading, when the user views the verification image 12 through the semitransparent shading picture, the user can clearly view the covered verification code, for example: "NU" shown in FIG. 1 b.

It is understood that, based on the degree of transparency of the pictures, the transparency refers to the degree of transparency and translucency of one picture, which affects the effect of overlapping with another picture (or background). The picture and the colorless and transparent stage are divided into 100 points, and the transparency is expressed by percentage.

The terminal may be, for example, a mobile terminal or a PC terminal, and the mobile terminal refers to a computer device that can be used in mobile, and broadly includes a mobile phone, a notebook, a tablet computer, a POS machine, and even a vehicle-mounted computer. But most of the cases refer to mobile phones or smart phones and tablet computers with multiple application functions; the PC terminal is exemplified by a desktop computer. The interface for displaying verification information and waiting for input may specifically be: a registration interface, a login and login abnormity verification interface, a business interface for purchasing, confirming payment and the like.

Example 1

Fig. 2 is a schematic flowchart of a verification information display method provided in embodiment 1 of the present invention, and referring to fig. 2, the method may be executed by a processor of a mobile terminal, and specifically may include the following steps:

step 22, determining target verification information;

step 24, generating a target verification image, wherein the target verification image is an image generated by adding a shading on a target area containing the target verification information;

it should be noted that, the steps 22 and 24 are generally steps executed in the background of the processor, and are not visible to the user, and the first implementation manner may be:

when detecting that the mobile terminal is adjusted to the interface needing to input the verification information, acquiring target verification information based on a random algorithm, for example: a combination of letters + numbers; then, a target verification image carrying the target verification information is constructed, and a preset shading is added to a target area containing the target verification information in the target verification image so as to enable the target verification information to be invisible.

The second implementation manner may be:

when detecting that the mobile terminal is adjusted to the interface needing to input the verification information, acquiring target verification information based on a random algorithm, for example: a combination of letters + numbers; then, generating image data of the target verification information to determine the lines of the target verification information; then, constructing image data corresponding to the preset shading, wherein the range of the second image data can cover the texture of the target verification information; then, adding the shading on the texture of the target verification information; it is understood that, because the preset shading and the texture of the target verification information are interwoven, the target verification information in the preset shading and the texture of the target verification information cannot be basically segmented by the computer, and the aim that the computer cannot identify the target verification information can be further achieved.

In the two implementation manners of step 22 and step 24, a specific implementation manner of the step of adding the preset shading may be:

adding a first shading on the target area based on a predetermined first shading adding rule; adding a second shading on the target area based on a predetermined second shading adding rule;

taking an image containing the target area to which the first ground tint and the second ground tint are added as a target verification image; wherein the first ground tint and the second ground tint are used for forming moire fringes so as to make the target verification information invisible.

It is understood that moire is the visual result of interference between two lines or objects at a constant angle and frequency, and that when the human eye cannot distinguish between the two lines or objects, only the interfering pattern is visible. From this, through rationally setting up first shading and adding rule and second shading and adding the rule, can make first shading and second shading produce moire fringe, and then make target verification information invisible. For example: the first shading adding rule is a linear function with a plurality of slopes as first slopes and different intercepts; the second shading adding rule is a linear function with a plurality of slopes as second slopes and different intercepts; wherein the first slope and the second slope are not equal.

And 26, displaying the target verification image and a first image, wherein the first image is used for being covered on the target verification image so as to enable the target verification information in the target verification image to be visible.

It should be noted that, the first implementation manner of step 26 may be:

generally, the interface for inputting the verification information sets a fixed position for the target verification image, for example: the position of the verification image 12 in fig. 1a and 1 b. Based on this fixed position, the processor may also set another fixed position for the first image that is different from the fixed position of the target verification image, such as: the position of the suspension frame 11 in fig. 1a and 1 b.

Based on this, the user can move the first image to overlay the first image on the target verification image, so as to view the target verification information overlaid by the preset shading through the first image.

A second implementation of step 26 may be:

different from the first implementation manner, the implementation manner sets a random position for the first image through a random algorithm, and with reference to fig. 3, may specifically include the following steps:

step 32, determining a first area occupied by the target verification image in a preset display interface;

step 34, determining target coordinates in a second area of the display interface, wherein the second area is an area except the first area in the display interface;

and step 36, displaying the first image in the display interface based on the target coordinate.

Examples are as follows: when jumping to a verification information display interface (simply referred to as a display interface), in general, a target verification image is fixed in a display area of the display interface and is marked as a first area (see fig. 1 a). Then, the remaining area is recorded as a second area, and target coordinates for displaying the first image, which are movable, are selected from the second area based on the size of the target verification image. Therefore, the first area and the second area are not overlapped, and the first image is further ensured not to be displayed on the target verification image.

Of course, the first region may be movable, but it is necessary to maintain a relative position with respect to the second region occupied by the first image so that the two do not completely overlap.

In order to improve the security of the verification information, a random algorithm may be used to obtain random coordinates in the second area, and the random coordinates may be used as target coordinates. Therefore, the machine cannot know the position of the target coordinate, the defect that the verification information is identified due to the fact that the machine uses software to 'drag' the first image to the target verification image which may occur is avoided, and the purpose of further improving the safety of the verification information is achieved.

For the two implementation manners of the step 26, it should be noted that the principle that the user can see the target verification information through the first image can be exemplified by:

the first image is an image with preset transparency generated according to the first shading and/or the second shading, for example: the first image carries the shading identical to the first shading, and therefore when a user views the target verification image through the first image, the shading on the first image is identical to the first shading on the target verification image, interference of interference patterns can be avoided, and further target verification information can be viewed.

In addition, in order to provide the definition for the user to view the target verification information through the first image, before the target verification image is displayed, the following steps may be optionally performed:

step 1 can be selected, the texture to be displayed of the target verification information is converted into a different texture from the texture on the first image, so that the difference with the background is increased. For example: when the first shading is on the first image, converting the first shading into shading corresponding to the second shading adding rule; or when the second shading is on the first image, the second shading is converted into the shading corresponding to the first shading adding rule.

Step 2 may be selected, and the gray value of the overlapping portion of the third shading and the first shading and the second shading is adjusted based on the gray values of the first shading and the second shading, so as to highlight the difference between the texture of the target verification information and the background.

Therefore, in the embodiment, the target verification image carrying invisible target verification information is generated by adding the shading on the target verification information; and displaying the target authentication image to the user together with the pre-constructed first image, since the first image is in a role of acting as a "decryption card", the user can make the target authentication information visible by overlaying the first image on the target authentication image. Moreover, the verification information is covered by the shading and is interwoven, so that the aim that the computer cannot automatically recognize the verification information can be fulfilled.

Example 2

Fig. 4 is a schematic flowchart of a verification information display method according to embodiment 2 of the present invention, and referring to fig. 4, the method may be executed by a processor of a mobile terminal, and specifically may include the following steps:

step 42, acquiring a first picture, wherein the first picture carries a verification code;

it should be noted that, the first implementation manner of step 42 may be:

based on user operation, in the process that the mobile terminal jumps to the verification code display interface, the processor determines the verification code to be displayed based on a random algorithm, for example: and combining the letters and the numbers, and displaying the combination on the first picture so as to obtain the first picture carrying the verification code.

A second implementation of step 42 may be:

based on user operation, the terminal initiates requests such as login and payment to the server, the server responds to the requests and returns verification codes generated by the server to the terminal, and the terminal processor acquires the verification codes and displays the verification codes on the first picture so as to acquire the first picture carrying the verification codes.

Step 44, adding a first preset shading and a second preset shading in the first picture to generate a second picture, wherein the verification code in the second picture is covered by the first shading and the second shading and is invisible;

it should be noted that, one implementation manner of step 44 may be:

and taking the acquired first picture as a trigger condition, and adding the first shading and the second shading in the first picture by the processor based on a preset first shading adding rule and a preset second shading adding rule.

The first shading and the second shading can be regular shading or irregular shading. To reduce the amount of data to be processed by the processor, a regular shading is preferred here. In addition, the first ground tint or the second ground tint alone can be a combination of a plurality of regular ground tint, and is not limited herein.

A second implementation of step 44 may be:

on the basis of the first implementation manner, the implementation manner further includes:

converting the shading of the verification code in the first picture into a third shading corresponding to the second shading adding rule;

the step of converting the shading of the identifying code into a third shading comprises the following steps: and converting the shading color of the verification code. For example: the shading color of the verification code is converted into the color of the first shading or the second shading or the similar color, so that the situation that the verification code can still be identified by the computer after the first shading and the second shading are added due to the fact that the color of the verification code is different from the colors of the first shading and the second shading is avoided.

A third implementation of step 44 may be:

on the basis of the first implementation manner and/or the second implementation manner, the gray value of the overlapping part of the third shading and the first shading and the second shading is adjusted based on the gray values of the first shading and the second shading.

It is understood that, because the gray value of the overlapped part is different from the gray value of the non-overlapped part or the gray value of other departments to a certain extent, when the user views the second picture through the semitransparent shading picture, the user can view the verification code more clearly.

In addition, for the shading rendering rules in the three implementations of step 44, the following conditions need to be satisfied:

the combination of the condition 1, the first shading and the second shading can cover the verification code; for example: the superposition of the two of the examples in embodiment 1 may produce moire fringes;

at least one of condition 2, the first shading, and the second shading is reproducible; thus, the processor may record its shading rules and then provide the possibility to build the semi-transparent shading picture in step 46.

Specific examples are: the first shading is a group of straight lines inclined to the right, and the second shading is a group of straight lines inclined to the left. When the density of the first shading and the second shading reaches a certain degree, the grains of the verification code, the first shading and the second shading become lines which are interwoven together, even moire fringes are generated, and then the computer cannot identify the verification code.

Of course, the shading adding rule can also be exemplified by other functions, such as quadratic function, etc., which are not listed here. In addition, the technology of adding shading is a mature prior art, and therefore, the detailed description thereof is omitted.

And step 46, displaying the second picture and a pre-constructed suspension frame, wherein a semi-transparent shading picture carrying the first shading or the second shading is embedded in the suspension frame, and the semi-transparent shading picture is used for covering the second picture so as to enable the verification code to be visible.

It should be noted that, at the same time or after the shading rendering rule is determined, the processor determines the shading to be carried by the semi-transparent shading picture based on the shading rendering rule, for example: when the shading adding rule comprises a first shading adding rule and a second shading adding rule, determining that the semitransparent shading picture needs to carry a first shading corresponding to the first shading adding rule or a second shading corresponding to the second shading adding rule.

As for a method of selecting whether to carry the first shading or the second shading, for example, there may be mentioned:

if the verification code is converted into the shading corresponding to the second shading adding rule in the step 44, the first shading is selected to be carried; if the verification code is converted into the shading corresponding to the first shading adding rule in step 44, the second shading is selected to be carried here. If the verification code is not converted in step 44, the conversion to any of the first shading and the second shading can be selected.

Based on this, in conjunction with fig. 1a and fig. 3, one implementation of step 46 may be as follows:

when jumping to a verification code display interface (referred to as a display interface for short), in general, the first picture is fixed in a display area of the display interface and is marked as a first area (see fig. 1 a). Then, the remaining area is designated as a second area, and target coordinates for displaying the floating frame, which are movable, are selected from the second area based on a predetermined size of the floating frame. Therefore, the first area and the second area cannot be overlapped, and the floating frame cannot be displayed on the first picture.

Of course, the first area may also be active, but it is also feasible that a certain relative position of the first picture and the floating frame needs to be maintained, so that the two do not completely overlap.

In order to improve the security of the verification code, a random algorithm may be used to obtain random coordinates in the second area, and the random coordinates may be used as target coordinates. Therefore, the machine cannot know the position of the target coordinate, the defect that the verification code is identified due to the fact that the machine drags the floating frame to the first picture by using software which is possibly generated is avoided, and the purpose of further improving the safety of the verification code is achieved.

Therefore, in the embodiment, the verification code is invisible by adding the first shading and the second shading to the picture carrying the verification code; and constructing a semitransparent shading picture carrying the first shading or the second shading to serve as a role of a decryption card, so that the verification code can be viewed through the semitransparent shading picture when a user drags and moves the semitransparent shading picture to the verification code. And because the verification code is covered by the first shading and the second shading, the first shading, the second shading and the third shading are interwoven together, so that the aim that a computer cannot automatically identify the verification code and a user can check the verification code through a semitransparent shading picture can be fulfilled.

Example 3

Fig. 5 is a schematic flow chart of a verification information display method provided in embodiment 3 of the present invention, and referring to fig. 5, the present invention is described in detail below from an exemplary perspective:

step 52, determining a first shading and a second shading

It should be noted that, for the rule for setting the first shading and the second shading, the terminal is generally stored locally; and then, the dynamic update is carried out by the server side. Thus, the processor of the terminal may determine the first shading and the second shading based on locally stored rules. For example:

slope (first slope) is the same as the set of primary mathematical functions with different intercepts: k1x + ib1(a1 function) to realize an equal density curve group in the same shading direction, and obtain a first shading picture 61;

a second shading picture 62 is obtained by implementing a certain shading-direction equal-density curve group by using a primary mathematical function group y (k 2x + ib 2) with a slope (second slope) different from that of the a1 function (a2 function).

Step 54, determine the verification code

It should be noted that there are various ways of generating the verification code, and here, a scheme of generating the verification code based on a random algorithm is exemplified, for example:

a random function is used to generate a random alphanumeric combination of four digits, each of which can be a-Z, a-z, 0-9 for a total of 58 possible cases. For example: the randomly derived authentication code is "Vy 1H" and a first picture 63 carrying the randomly derived authentication code can be constructed.

Step 56, synthesize the second picture

The first shading picture 61 and the second shading picture 62 are combined into the first picture 63, or the first shading and the second shading are combined into the first picture 63, or the same shading as the first shading and the second shading is added to the first picture 53, so that the second picture 64 is generated.

It will be appreciated that the verification code in the second picture 64 is not visible because the first and second shading can obscure the verification code "Vy 1H".

In addition, in order to ensure that the verification code is invisible, the color of the verification code can be converted into the same color as that of the second shading or the first shading.

Step 58, constructing a suspension frame

It should be noted that, one implementation of step 58 may be:

and determining the size of the semitransparent shading picture and the size of the suspension frame based on the size of the second picture, then constructing the semitransparent shading picture, and embedding the semitransparent shading picture into the suspension frame capable of being dragged to form an auxiliary identification tool.

The step of constructing the semitransparent shading picture can be as follows:

filling the first shading or the second shading in a picture, and then adjusting the transparency of the picture to obtain the semi-transparent shading picture 65. Taking the shading in the translucent shading picture 65 as an example of the first shading, when it coincides with the shading in the second picture, the difference between the background shading (the second shading) and the text shading (the verification code shading) can cause different shadows due to the absence of the first shading, and the user can see the verification code.

Step 510, displaying the floating frame and the second picture

It should be noted that the position of the displayed suspension frame and the position of the second picture need to satisfy:

the floating frame and the second picture can not be overlapped so as to prevent the verification code from being directly viewed. For example:

the random algorithm x0 ═ rand ()/getWindowWidth (), y0 ═ rand ()/getWindowHeight () is used to obtain the coordinates of any random position other than the position of the second picture, for example: (x0, y0), and the suspension frame is placed at (x0, y 0). Therefore, when the floating frame is not positioned right above the verification code, the user can not recognize the content under the verification code by naked eyes.

Step 512, drag the floating frame to coincide with the second picture

It will be appreciated that when the user drags the floating frame over the second picture 64, and the covered authentication code segment is visually identified (64/65) when it coincides with the first shading in the second picture, the user can enter the visible authentication code and wait for background identification verification.

Therefore, in the embodiment, the verification code is invisible by adding the first shading and the second shading to the picture carrying the verification code; and constructing a semitransparent shading picture carrying the first shading to serve as a role of a decryption card, so that when a user drags and moves the semitransparent shading picture to the verification code, the verification code can be viewed through the semitransparent shading picture. The verification code is covered by the first shading and the second shading, and the first shading, the second shading and the third shading are interwoven, so that the aim that a computer cannot automatically recognize the verification code and a person can recognize the verification code through simple operation can be achieved. Under the condition that the verification codes of various kinds of software are widely used at present, the safety can be ensured, and the operation complexity of a user can be reduced.

In addition, for simplicity of explanation, the above-described method embodiments are described as a series of acts or combinations, but it should be understood by those skilled in the art that the present invention is not limited by the order of acts or steps described, as some steps may be performed in other orders or simultaneously according to the present invention. Furthermore, those skilled in the art will appreciate that the embodiments described in the specification are presently preferred and that no particular act is required to implement the invention.
