Display method and display device of peeping-preventing visible code

An embodiment of the invention discloses a display method and a display device of a peeping-preventing visible code. The method includes receiving at least one code input into a code input box by a user; selecting and displaying a color of the code and a background color; respectively adjusting the color of the code and the background color into a preset range, and obtaining the peeping-preventing visible code which is visible in a preset distance range; and displaying the peeping-preventing visible code through the code input box. As the user can see the correctness of the input code when inputting the code, if the user finds wrong inputting, the user can correct the code immediately, the problem that a wrong code is submitted to cause time waste is resolved, and meanwhile safety of the code is improved. Meanwhile, as the input code only can be seen at short range, and the code cannot be seen clearly at a long distance, a certain function of code peeping prevention is achieved.
