Detailed Description
In order to make the technical solutions of the present invention better understood, 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 only a part of the embodiments of the present invention, and not all of the 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 invention.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in other sequences than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Fig. 1 is a flowchart of a password input method according to an embodiment of the present invention, where the embodiment is applicable to a situation where a user inputs a password through a virtual keyboard, and the method can be executed by a password input device, which can be implemented in the form of hardware and/or software, and the device can be configured in an electronic device with corresponding data processing capability. As shown in fig. 1, the method includes:
s110, when a password input event is detected in the target application program, displaying a keyboard input interface; the keyboard input interface comprises candidate pictures, and the candidate pictures are associated with candidate character elements.
The target application program is an application program requiring a user to input various passwords, and the purpose of inputting the passwords can be identity authentication and the like in various scenes. The password input event is an event triggered after the user performs a corresponding operation, for example, the user clicks a 'payment order' by using payment software to input a payment password, and the input software unlocks the password when entering a certain program. The keyboard input interface in the invention can be a traditional 9-key or 26-key layout, so that users can have too strong sensory difference when using the password input method of the application. The candidate character elements may be characters that a conventional keyboard can support to input, such as elements of numbers, english letters, and the like.
Specifically, after a user triggers a password input event in a target application program, a keyboard input interface is displayed on a terminal screen where the target application program is installed. Different from the traditional keyboard input interface which directly displays characters, the keyboard input interface is displayed by replacing the characters with the candidate pictures, and the candidate pictures displayed in the input interface are not characters. Based on the display mode, even if a malicious program detects the input content of the user, the true password content input by the user cannot be determined, and only which picture is clicked can be known. For example, when the keyboard input interface of the numeric keyboard layout is presented to the user, 10 candidate pictures are provided, 10 corresponding candidate character elements are provided, and each candidate picture is associated with one candidate character element. When the user selects one of the pictures, only the method executor who has generated the keyboard layout can know the candidate characters associated with the candidate picture according to the association relationship between the candidate picture and the candidate keyboard elements when the keyboard layout is generated.
It should be noted that the candidate picture should show the information of the keyboard element associated with the candidate picture, for example, the candidate picture associated with the keyboard element "a" should contain a letter a in the picture content, so that the user can determine that the keyboard element actually associated with the picture is "a".
And S120, acquiring a target picture selected from the candidate pictures.
Specifically, after a keyboard input interface is displayed for a user, it is determined that the user clicks a candidate picture selected by a screen in the keyboard input interface, and the candidate picture selected by the user is taken as a target picture.
S130, determining a target character element according to the target picture based on the incidence relation between the candidate picture and the candidate character element, and taking the target character element as input password information.
Specifically, different candidate pictures have different attribute information, and the different candidate pictures and their associated candidate character elements may be distinguished based on the attribute information of the candidate pictures. After determining the attribute information of the picture, the unique candidate character associated with the attribute information may be determined according to the association relationship between the preset candidate picture and the candidate character element, and the candidate character is determined as a target character, which is the password information actually desired to be input by the user, and the candidate characters in the association relationship should be in one-to-one correspondence with the candidate picture. By such a password input and determination method, even if a malicious program acquires the contents clicked by the user, the password information actually input by the user cannot be determined according to the target picture selected by the user under the condition that the association relationship is not clear, so that the security during password input is improved.
For example, when the keyboard layout is a numeric keyboard layout, different pixel values may be set for 10 candidate pictures replacing 10 characters of 1 to 10, respectively, and its associated candidate character may be set for each pixel value, thereby generating an association relationship between the candidate pictures and the candidate characters. When the user clicks the candidate picture to determine the target picture, the candidate character associated with the target picture can be quickly determined according to the pixel value and the association relation of the target picture, so that the password information which the user actually wants to input is determined.
Optionally, the determining, based on the association relationship between the candidate picture and the candidate character element, the target character element according to the target picture includes:
acquiring a target picture name of the target picture; and determining candidate character elements associated with the target picture name based on the association relationship between the candidate pictures and the candidate character elements, and determining the associated candidate character elements as the target character elements.
Specifically, the candidate character associated with the target picture may be determined by using the picture name in the picture attribute information. The image names of other attribute information such as pixels, colors and sizes in the relative attribute information are undoubtedly higher in efficiency and strong in operability when different candidate images are distinguished and associated candidate elements are determined. Therefore, in the invention, when the association relationship is generated, the picture name can be used as the attribute information of the picture to be associated with the candidate character element, for example, the picture name "a" is associated with the candidate character element "1", and the picture name "B" is associated with the candidate character element "2".
The embodiment of the invention replaces the characters in the password input keyboard with the pictures, establishes the association relationship between the pictures and the character elements, and can determine the password information represented by the target picture only under the condition of knowing the association relationship, thereby avoiding the password information from being read maliciously and ensuring the security when the password is input.
Fig. 2 is a flowchart of a password input method according to another embodiment of the present invention, and the present embodiment is optimized and improved based on the above embodiment. As shown in fig. 2, the method includes:
s210, when a password input event is detected in the target application program, displaying a keyboard input interface; the keyboard input interface comprises a candidate picture, and the candidate picture is associated with a candidate character element.
And S220, acquiring a target picture selected from the candidate pictures.
And S230, determining a target character element according to the target picture based on the incidence relation between the candidate picture and the candidate character element, and taking the target character element as input password information.
S240, determining the playing state of the password input terminal for installing the target application program; displaying earphone connection prompt information under the condition that the password input terminal is in a play-out state; and under the condition that the password input terminal is in an earphone playing state, the password information is broadcasted in a voice mode.
The external playing state is a state of using an external player or a terminal with a player for sound public playing, and under the state, the password content of the voice broadcast is easily intercepted by other people.
Specifically, an auxiliary mode for assisting a disabled person or a visually impaired person in operating the terminal is gradually popularized in terminals such as mobile phones, and in the auxiliary mode, the terminal can automatically read contents such as interface characters and controls in mobile phone apps clicked by a user. When a user inputs a password in the auxiliary mode, the user needs to perform voice broadcasting on the password character actually input by the user to help disabled people or vision disorder to determine the input content of the user. The voice playing mode enables password information input by a user to be easily heard by other people nearby. Therefore, before the password information input by the user is broadcasted in a voice mode, the playing state of the password input terminal is detected, if the user is in the play-out state, the earphone connection prompt information is displayed, and the information can be in a voice content form; and under the condition that the password input terminal is in an earphone playing state, the password information is broadcasted in a voice mode. According to the method and the device, before the password information is broadcasted in a voice mode, the terminal broadcasting state is detected, the broadcasting is carried out in a safe mode, the earphone connection information is prompted in an unsafe mode, and the safety of inputting the password when the user starts the auxiliary mode is improved.
Optionally, the determining the play state of the password input terminal for installing the target application program includes:
playing the password information; monitoring environmental sound through a microphone; and if the monitored environmental sound comprises the password information, determining that the password input terminal is in an external playing state.
Specifically, for the determination of the playing state of the terminal, the current detection method in software can only determine whether an external audio playing device is connected, and cannot distinguish whether the external audio playing device is an earphone or a sound. Therefore, in order to further improve the detection accuracy of the playing state of the password input terminal, the invention can monitor the environmental sound through the microphone to determine whether the password information exists in the surrounding environmental sound, thereby effectively avoiding the situations that the user uses invalid external audio playing equipment to perform voice broadcast of the password information, and the user abandons the use of an earphone in the voice broadcast process, and the like.
S250, encrypting the password information through an asymmetric encryption algorithm; and sending the encrypted password information to a server for indicating the server to verify the encrypted password information.
Specifically, the password information input by the user is encrypted according to the prestored asymmetric encryption algorithm, and the asymmetric encryption has the advantage that even if a malicious program cracks the encryption algorithm, the encrypted password information cannot be decrypted according to the cracked encryption algorithm to obtain the password information, so that the safety of the password information after encryption is further improved. Meanwhile, an asymmetric decryption algorithm corresponding to the asymmetric encryption algorithm exists in the server, and the server can determine password information input by a user according to the asymmetric decryption algorithm and verify the password information.
In the embodiment of the invention, the playing state of the terminal is detected before the password information is broadcasted in a voice mode, the broadcast is carried out when the terminal is safe, and the earphone connection information is prompted when the terminal is not safe, so that the safety of inputting the password when a user starts the auxiliary mode is improved; the password information input by the user is encrypted by using the asymmetric encryption algorithm, so that the encrypted password information is prevented from being cracked by a malicious program which acquires the encryption algorithm.
