TECHNICAL FIELD
The present invention relates to the field of communications technologies, and in particular, to a verification code generation and verification method and apparatus.
BACKGROUND
A verification code is a public full-automatic program for distinguishing whether an access requester is a computer program or a person. The verification code is usually used to prevent malicious programs such as Trojans from cracking a password, casting votes repeatedly, bumping in a forum, and so on, in order to prevent a certain hacker from making persistent login attempts by using a specific program to crack certain registered users violently or the like. The verification code is generally composed of lines and irregular characters, and is primarily intended to prevent a hacker from making a password into data and stealing the password. Currently, mainstream verification codes have the following forms:
1. A verification code is composed of only digits and letters, which may be all letters or all digits, and is a random string of a plurality of bits. This type of verification code is the most original, and its verification effect is almost zero in the current technical environment.
2. A verification code is an image verification code consisting of random digits+random uppercase letters+random interfering pixels+random positions+random length. The verification code is randomly generated, relatively secure, but difficult for verification and inconvenient for a user to input.
3. An advertisement verification code: a part of the content in an advertisement is input, which can bring additional revenues to a website and is also refreshing to the user.
4. A question verification code: a verification code is input mainly in a question-and-answer manner.
The above technologies have many disadvantages. First, every time after inputting a username and a password, the user has to switch to a keyboard to input characters. Especially, if the user needs to input characters on a touchscreen, the process is rather complicated, which brings poor user experience and is troublesome to the user. Secondly, a verification code usually includes stacked texts and is user-unrecognizable, which forces the user to keep refreshing the verification code image. Thirdly, a verification code is input to prevent attacks from malicious programs and keep a server system in secure state, but in practice, it mostly prevents the user from using the service pleasantly, causes troubles to the user, and brings no significant improvement to security.

DETAILED DESCRIPTION
The following clearly describes the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are merely a part rather than all of the embodiments of the present invention. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
With reference to FIG. 1, the following describes a verification code generation and verification method according to an embodiment of the present invention. As shown in FIG. 1, the method includes the following steps:
S11. Display a verification code display region on a touch display module, where the verification code display region includes at least one user-recognizable verification code element.
In an embodiment of the present invention, the verification code element may be any one of three elements: text, color, and image, or a combination of any two of the three elements, or a combination of the three elements. The combination may be random, or may be formed according to preset rules, and the displayed verification code element is user-recognizable.
In an embodiment of the present invention, the displaying a verification code display region on a touch display module includes: selecting an initial verification code region on the touch display module according to a preset parameter; dividing the initial verification code region into at least two sub-regions according to a preset rule; and generating a user-recognizable verification code element in a random position in each of the at least two sub-regions to form the verification code display region, and storing a position of the user-recognizable verification code element in the corresponding sub-region.
In an embodiment of the present invention, as shown in FIG. 6A, the initial verification code region may be divided into four sub-regions of an equal size, and above each sub-region there is a prompt region, which can prompt whether a user touch is correct. It can be understood that the number of sub-regions may be another number such as 3, 5, or 6, and the sizes of the sub-regions may also be unequal. It can be understood that the above embodiment is only an example given for helping understand the present invention, and shall not be construed as a limitation on the embodiment of the present invention. Persons of ordinary skill in the art may derive other manners of dividing into sub-regions without creative efforts.
In an embodiment of the present invention, a shape of the sub-region is any one of four shapes: triangle, quadrangle, circle, and cuboid, or a combination of at least two of the four shapes. As shown in FIG. 6B, the shape of the sub-region may be a triangle, a circle or a rectangle. As shown in FIG. 6C, the shape of the sub-region may be a 3-dimensional image. In an embodiment of the present invention, as shown in FIG. 6B to FIG. 6C, a character in a figure represents a verification code element, and irregular lines represent interfering codes, and the interfering codes may be added into the sub-region to increase security of the verification code without affecting a user's normal use.
In an embodiment of the present invention, after the displaying a verification code display region on a touch display module, where the verification code display region includes at least one user-recognizable verification code element, the method further includes: displaying a verification code prompt region on the touch display module, and displaying a selection rule correlated with the verification code element in the verification code prompt region, where the selection rule is used to prompt the user to select the verification code element in the verification code display region according to the selection rule.
In an embodiment of the present invention, the selection rule includes semantic representation, pictographic representation, and logical representation correlated with each selected verification code element, and a selection order of each verification code element. Semantic representation is to indicate the selection rule to the user by using a user-readable sentence, where the sentence may be in English or in another language, for example, “Please select a red cube, a black ball, and a blue star,” and so on; pictographic representation is to indicate the selection rule to the user by using an image similar to a verification code element; and logical representation requires the user to perform a logic operation, and, according to an operation result, obtains a verification code element correlated with the selection rule. It can be understood that the selection rule may be expressed in one or several manners correlated with the verification code element. The example here is merely intended to help understand the embodiment of the present invention and shall not be construed as a limitation on the embodiment of the present invention.
FIG. 4 illustrates a specific example of a pictographic representation of a selection rule. As shown in FIG. 4, the element displayed in the prompt region is a quadrangle, and therefore, the user needs to select a quadrangular verification code element in the verification code display region. It can be understood that the above example is merely intended to help understand the embodiment of the present invention and shall not be construed as a limitation on the technical solution of the present invention. Persons of ordinary skill in the art may derive other implementation manners without creative efforts, for example, the element displayed in the prompt region is text, the element displayed in the prompt region is an image, and so on.
FIG. 5 illustrates a specific example of a logical representation of a selection rule. In an embodiment of the present invention, the prompt information is used to prompt the user to perform calculation according to the element displayed in the verification code prompt region, and prompt the user to select the verification code element compliant with a calculation result. As shown in FIG. 5, the element displayed in the prompt region is 3+5, and therefore, the user needs to select a verification code element of the result “8” in the verification code display region. The verification code element may indicate the result directly or indirectly. For example, the verification code element is 4+4. It can be understood that the above example is merely intended to help understand the embodiment of the present invention and shall not be construed as a limitation on the technical solution of the present invention. Persons of ordinary skill in the art may derive other implementation manners without creative efforts, for example, the user is prompted to select a specific color, select a combination of elements such as color, digit, text, and so on, or select a specific state.
S12. Sense a touch action of the user on the touch display module, and determine a position of the touch action on the touch display module.
After triggering the verification, the user needs to perform a touch action on the touch display module. Through the touch action, the user can decide the to-be-selected position discretionarily.
In an embodiment of the present invention, in addition to the sensing the touch action of the user on the touch display module and determining the position of the touch action on the touch display module, the method further includes: recording an input rule of the user, so as to facilitate subsequent judgment in step S13.
S13. Compare whether the position of the touch action of the user on the touch display module is the same as the position of the verification code element to determine whether a verification code is correctly input.
In an embodiment of the present invention, whether the position of the touch action of the user on the touch display module is the same as the position of the user-recognizable verification code element in the corresponding sub-region can be compared to determine whether the verification code is correctly input.
In an embodiment of the present invention, correspondingly, in addition to the comparing whether the position of the touch action of the user on the touch display module is the same as the position of the verification code element, the method further includes: comparing whether the input rule of the user is the same as the selection rule displayed in the verification code prompt region to determine whether the verification code is correctly input.
The verification code generation and verification method in the embodiment of the present invention is convenient for the user to input a verification code for verification, and brings a good verification effect while facilitating operations.
The following describes a verification code flowchart and several specific implementation manners according to an embodiment of the present invention with reference to FIG. 2 to FIG. 3.
With reference to FIG. 2A to FIG. 2F, the following describes a specific implementation manner of a verification code generation and verification method according to an embodiment of the present invention. As shown in FIG. 2A, a verification code display region and a verification code are generated on the touch display module, the user inputs a username and a password, and then clicks “Verify” to verify the verification code. As shown in FIG. 2B, if a region that includes a verification code element in a verification code system receives a user click or touch signal, the display region on the touch display module in the verification code system displays a corresponding color or text and displays a prompt of being verified as correct to feed back the verification information to the user. As shown in FIG. 2C, if a display region that includes no verification code element in the verification code system receives a user click or touch signal, the verification code system displays an error prompt, and then, after the verification error occurs, the verification code region shown in FIG. 2D is refreshed automatically for the user to start over the verification. The user starts over a touch action on the touch display module. As shown in FIG. 2E to FIG. 2F, after the user performs the touch action again and all verification code elements are verified as correct, the system automatically enters an interface after the verification success for the user to perform subsequent operations.
With reference to FIG. 3A and FIG. 3B, the following describes another specific implementation manner of a verification code generation and verification method according to an embodiment of the present invention. The user clicks “Verify,” and the system enters a verification code verification window for the user to perform the verification. As shown in FIG. 3A, a verification code generation program groups verification code regions automatically, where each group has a prompt module indicating whether the verification succeeds. The verification code generation program automatically fills a group with texture and characters, where a font, size, color, character type, rotation angle, and position of the characters may change randomly. A verification code image has texture, which prevents a Trojan program from recognizing characters in the image, and the verification code generation program creates many clickable display sub-regions in each group automatically. For places with characters, a clickable region is just available for being clicked by the user without errors, and other display sub-regions may be of unequal sizes.
As shown in FIG. 3B, a prompt region above the verification code region prompts the user to click the verification code elements in alphabetical order, and the user needs to click the verification code element by following a rule determined according to the prompt information, so as to verify a group. In a visual or audible manner, a verification code may feed back whether the current group is verified as correct. If the current group is verified as incorrect, the verification code is refreshed; or, if the verification succeeds, the user continues to click and verify the next group until all groups are verified as correct. After all groups are verified as correct, the system returns to a page after the verification success.
The verification code generation and verification method in the embodiment of the present invention enables the user to input a verification code more quickly and increases the fun of verifying the user verification code. Input by using a touch action makes the input of the verification code no longer a burden for the user. Further, depending on specific requirements in an application scenario, security intensity of verifying the verification code can be changed easily by adding groups, adding clickable hotspot regions in each group, or adding an order of verifying the groups for limitation.

In an embodiment of the present invention, the displaying module 801 includes: a selecting unit 8011 configured to select an initial verification code region on the touch display apparatus according to a preset parameter; a sub-region dividing unit 8012 configured to divide the initial verification code region, which is selected by the selecting unit 8011, into at least two sub-regions according to a preset rule; and a verification code generating unit 8013 configured to generate a user-recognizable verification code element in a random position in each of the at least two sub-regions to form the verification code display region, where the two sub-regions are a result of dividing by the sub-region dividing unit, and store the position of the user-recognizable verification code element in a corresponding sub-region.
Correspondingly, the comparing, by the judging module 803, whether the position of the touch action of the user on the touch display apparatus is the same as the position of the verification code element to determine whether a verification code is correctly input, specifically includes: comparing, by the judging module 803, whether the position of the touch action of the user on the touch display apparatus is the same as the position of the user-recognizable verification code element in the corresponding sub-region to determine whether the verification code is correctly input.
In an embodiment of the present invention, the verification code element is any one of three elements: text, color, and image, or a combination of any two of the three elements, or a combination of the three elements.
In an embodiment of the present invention, a shape of the sub-region is any one of four shapes: triangle, quadrangle, circle, and cuboid, or a combination of at least two of the four shapes.
In an embodiment of the present invention, the displaying module 801 further includes a prompting unit 8014, where the prompting unit 8014 is configured to display a verification code prompt region on the touch display apparatus, and display a selection rule correlated with the verification code element in the verification code prompt region, where the selection rule is used to prompt the user to select the verification code element in the verification code display region according to the selection rule.
In addition to the sensing the touch action of the user on the touch display apparatus and determining the position of the touch action on the touch display apparatus, the position determining module 802 is further configured to record an input rule of the user.
Correspondingly, in addition to the comparing whether the position of the touch action of the user on the touch display apparatus is the same as the position of the verification code element, the judging module 803 is further configured to: compare whether the input rule of the user is the same as the selection rule displayed in the verification code prompt region to determine whether the verification code is correctly input.
