and randomly selecting a background picture of the playback picture.
specifically, the character sequence to be redisplayed is temporarily cached in the memory, and when the generation of the redisplayed image is completed, the temporary cache of the character sequence to be redisplayed in the memory is deleted. In this step, once the generation of the redisplay picture is completed, the plaintext of the character sequence to be redisplayed can be deleted, so that the risk of the plaintext existing in the memory is reduced as much as possible, and the redisplay picture may not be displayed on the terminal interface.
Specifically, rendering is performed in a playback area of the terminal interface according to the generated playback picture, and the playback picture is displayed in the playback area.
In the embodiment, the mode that the input content is instantly encrypted and the echoed content is displayed in the picture is adopted, the input content of the user is instantly encrypted, and the original input content is only cached in the memory for a short time, so that the input safety of the terminal is effectively ensured, and the condition that the input content is stolen through the memory from the outside is effectively prevented.
In one embodiment, the playback strategy includes a background picture and character display parameters, the character display parameters include character position coordinates, character colors and character deflection parameters, as shown in fig. 4, the playback picture is generated according to the playback strategy and a character sequence to be played back, and the method includes the following steps:

404, acquiring a character position coordinate, a character color and a character deflection parameter of a current character in a character sequence to be redisplayed according to a redisplay strategy;
specifically, the character position coordinates, the character colors, and the character deflection parameters of the current character in the character sequence to be redisplayed are randomly obtained from the redisplay strategy, and of course, in this step, the character position coordinates, the character colors, and the character deflection parameters of the current character may also be obtained according to the character display parameters preset by the user.
here, the character deflection parameters may include a Z-direction inclination angle and a Y-direction offset angle, which may constitute a character deflection matrix;
specifically, the terminal processes the current character according to the character color and the character deflection matrix to obtain a character image of the current character, and then draws the character image on the background of the echoed picture according to the character position coordinates.
specifically, one character can be selected from the un-drawn characters each time as a new current character, and all the characters in the character sequence to be redisplayed are sequentially drawn.
In specific implementation, the echo strategy may further include an interference line parameter and an interference point parameter.
here, the disturbance line parameters include the number of disturbance lines, and the start point position, end point position, width, and color of each disturbance line;
specifically, interference line parameters are obtained, the interference line is drawn according to the starting point position, the end point position, the width and the color of one interference line, the drawing step is repeated, and all the interference lines are drawn in sequence.
And step 414, drawing interference points on the echoed pictures according to the interference point parameters in the echoed strategies.
Here, the interference point parameters include the number of interference points, and the position, size, and color of the interference points.
Specifically, the random position plots the interference point.
In step 412 and 414, the interference lines and/or interference points should be drawn above the characters or at the top layer of the playback picture to better perform the interference function.
In particular, the character display parameters may also include character animation effects.
And step 416, randomly acquiring a character animation effect of each displayed character in the playback picture from the playback strategy, and dynamically displaying each displayed character according to the character animation effect.
The displayed characters are characters displayed on the interactive interface of the echoed picture, namely characters which can be observed by a user; for example, when the length of the playback area is the set length, part of the characters in the playback picture may exceed the playback area, and therefore, the characters are not displayed on the interactive interface, and the playback picture may be displayed in a horizontal scrolling animation manner, so that all the characters in the playback picture are sequentially displayed in the playback area, and at this time, the displayed characters are the characters of the playback picture located in the playback area.
Specifically, the refresh time may be set such that each character is dynamically displayed. For example, each character is displayed in a time-hopping manner in the echoed picture and is stopped for a period of time for the user to watch.
In this embodiment, in the generated echoed picture, besides the character sequence to be echoed, a plurality of composite image confusion techniques are also utilized, the character sequence to be echoed is processed, and each displayed character can have a certain animation effect, so that third-party image recognition can be effectively interfered.
In one embodiment, the method further comprises the steps of:
and returning to the step of encrypting the received input character sequence to obtain encrypted information when the input character sequence is detected to be changed/edited again by the user.
In this embodiment, when the user edits or changes the input content again, the encryption step and the reproduction picture generation step are repeated, so that the new input content is encrypted and stored and the picture is displayed.
In one embodiment, the method further comprises the steps of:
when a request for closing the playback is received, deleting the playback picture;
specifically, the user clicks the playback button switch, and the terminal receives the request for closing the playback, deletes the playback picture, and can also hide the playback area.
Here, the redisplay button switch is a single switch, and is not clickable when no input content exists in the information editing frame; when input content exists in the information editing frame, a playback request is generated by clicking for the first time, the information editing frame is hidden, and a playback area is displayed; and clicking again to generate a request for closing the redisplay, hiding the redisplay area and displaying the information editing frame. However, in the specific implementation process, the playback button switch can also be composed of two switch buttons, one is used for turning on the playback and the other is used for turning off the playback.
In this embodiment, when detecting a screen capture and/or screen recording event, the terminal deletes the content and the playback picture in the information editing frame.
Specifically, when a user starts inputting, the user clicks an information editing frame, a soft keyboard pops up on an interaction interface of the terminal, the redisplay is in a closed state by default, the terminal also starts screen capture/screen recording event monitoring while generating a symmetric encryption key, and once screen capture and/or screen recording events are detected, the redisplay pictures and the content in the information editing frame are immediately removed.
Based on the above steps, the present embodiment may adopt a screen capture/recording prevention technology, which prevents the interface from being captured or recorded during the input process, and further ensures the input security.
