Detailed Description

The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.

The hardware wallet needs to acquire the PIN code input by the user in the processes of setting the PIN code of the hardware wallet or verifying the PIN code input by the user and the like. There are several ways to enter the PIN code.

One way is that the user can directly enter a PIN code on a computer or a mobile phone to which the hardware wallet is connected. However, this method has a great safety hazard, and a hacker can acquire the PIN code by monitoring the keyboard or the mouse, etc.

Alternatively, the user can switch and input the PIN code through two limited buttons on the hardware wallet, and after the user switches and selects the required number by using the two buttons, the user can press the two buttons simultaneously for confirmation, and then the user needs to repeat the PIN code again for confirmation. This is extremely inconvenient for the user, takes a long time to input the PIN code, and also reduces the life span due to the frequent use of the two buttons.

In another mode, a full keyboard is arranged on the hardware wallet, similar to a numeric keypad on the right side of a computer keyboard, and a user can directly use the full keyboard on the hardware wallet to input a PIN code. However, the full keyboard used at low frequency not only increases the cost of the hardware wallet, but also makes the hardware wallet very large and not portable.

In order to overcome the problems caused by the above manner, in the embodiment of the application, when the verification code is input into the hardware wallet, the random number is displayed in the display area corresponding to each verification code, and is adjusted based on an adjustment instruction input by a user on the transaction device, so as to obtain the bit character to be verified. Even if the transaction device is monitored by a hacker, the hacker cannot deduce the verification code because the hacker does not know the random number generated by the hardware wallet, so that the purpose that the verification code cannot depart from the hardware wallet is realized through the combination of the transaction device and the hardware wallet, and the input security of the verification code is improved.

Fig. 1 is a flowchart of an interaction of a method of inputting a verification code according to an embodiment of the present application. The method shown in fig. 1 may be performed by a transaction device and a security device. The security device comprises a security chip, the security chip can independently perform operations such as key generation, encryption and decryption, and the like, and can store keys, feature data and the like so as to provide encryption and security authentication services for the device. The following description will take the security device as a hardware wallet as an example, but the application is not limited thereto. The transaction device in the embodiment of the present application may be any device capable of performing digital currency transactions, such as a computer, a mobile phone, a tablet computer, and the like. The hardware wallet in the embodiment of the present application may also be referred to as a "currency shield" or the like. Optionally, the transaction device and the hardware wallet may communicate via a USB interface, bluetooth, or radio frequency, etc.

The verification code includes N target characters, where N is a positive integer, and the verification code may be, for example, the PIN code, a mnemonic word, a set question answer, or other passwords. As shown in FIG. 1, the transaction method 100 may include some or all of the following steps. Wherein:

at 110, the hardware wallet displays the random character to the user on a display area corresponding to an ith target character of the N target characters. Wherein i is more than or equal to 1 and less than or equal to N.

At 120, the transaction device obtains adjustment instructions entered by the user.

And the adjusting instruction is used for instructing the hardware wallet to adjust the random character displayed on the display area corresponding to the ith target character according to a preset character sequence until the random character is adjusted to the ith target character.

At 130, the transaction device sends the adjustment instruction to the hardware wallet.

At 140, the hardware wallet adjusts the random character according to the adjustment instruction according to a predetermined character sequence until the random character is adjusted to the ith target character.

Specifically, if the verification code to be input by the user includes N target characters, the hardware wallet may display a random character on a display area corresponding to each target character, and after the user sees the random character from the display screen of the hardware wallet, the user may input an adjustment instruction on the transaction device, where the adjustment instruction may be used to adjust the random character. The adjustment instruction may include, for example, a first adjustment instruction that adjusts the random character in a forward order or a second adjustment instruction that adjusts the random character in a reverse order. The user inputs an adjustment command until the random character displayed on the display area corresponding to the bit target character is adjusted to be equal to the bit target character. When the characters displayed on the N display areas corresponding to the N-bit target characters are all adjusted to be corresponding target characters, the N target characters displayed on the N display areas are the verification codes input to the hardware wallet by the user. After the hardware wallet obtains the N target characters in the verification code, corresponding operations, such as verifying or processing the N target characters, may be performed on the N target characters.

Wherein, the adjusting instruction can be input by the user by using a keyboard, a soft keyboard or a mouse of the transaction device. For example, the user can adjust the random characters according to the character sequence by using an up key "↓" and a down key "↓" of the computer keyboard; or, the user can use the left turn key "←" and the right turn key "→" of the computer keyboard to adjust the random characters in the character order; or, the user also adjusts the random characters according to the character sequence by the up-and-down rolling of the mouse wheel; or, the user can also use a soft keyboard or a volume key on the mobile phone to realize the adjustment of the random characters; alternatively, the user may use other keys to effect the adjustment. The embodiment of the present application is not limited to this, and any manner that can realize inputting the adjustment instruction to the transaction device should fall within the protection scope of the embodiment of the present application.

The verification code input to the hardware wallet comprises N-bit characters which can be numbers, letters, a combination of numbers and letters, or other characters which can be used as the verification code.

Optionally, at 110, the displaying, by the hardware wallet, a random character to the user on a display area corresponding to an i-th target character of the N-bit target characters includes: and when the character displayed on the display area corresponding to the (i-1) th target character in the N-bit target characters is adjusted to be the (i-1) th target character, the hardware wallet displays the random character to the user on the display area corresponding to the (i) th target character.

That is, when the user adjusts the random character displayed on the display region corresponding to the i-1 th target character among the N-bit target characters of the authentication code to the i-1 th target character, a confirmation instruction may be input to the transaction apparatus and transmitted to the hardware wallet by the transaction apparatus. And after receiving the confirmation instruction, the hardware wallet displays a random character to the user on the display area corresponding to the ith target character. Similarly, when the random character displayed on the display area corresponding to the ith target character is adjusted to the ith target character by the user, the user inputs a confirmation instruction, and after receiving the confirmation instruction, the hardware wallet continues to display the random character to the user on the display area corresponding to the (i + 1) th target character. And sequentially, adjusting characters displayed on N display areas corresponding to the N-bit target characters to be respectively corresponding target characters, thereby completing the input of the N-bit target characters.

For example, assume that the verification code includes 6 target digits, respectively 180531. Fig. 2(a), 3(a), 4(a) and 5(a) show the display screen of the hardware wallet, and the dashed boxes on the display screen represent six display areas, which correspond to the 6-digit numbers in the verification code one by one from front to back. Fig. 2(b), fig. 3(b), fig. 4(b) and fig. 5(b) show a computer keyboard, which includes an up key "↓" and a down key "↓" for inputting an adjustment instruction, an Enter key (Enter) for inputting a confirmation instruction, and a delete key (Backspace) for inputting a delete instruction.

Fig. 2(a) and 2(b) are schematic diagrams illustrating a user adjusting the random number in the display area corresponding to the first target digit. The hardware wallet first displays a random number (assumed here to be 2) to the user on a first display area. When the user presses "≠ once on the computer keyboard, the value of the random number displayed on the first display area is added with 1; and when the user presses "↓" once on the keyboard of the computer, subtracting 1 from the value of the random number displayed on the first display area. Therefore, after the user presses "↓" once on the keyboard of the computer, the computer sends the adjusting instruction to the hardware wallet, and after the hardware wallet receives the adjusting instruction of "↓" once, the random number 2 displayed on the first display area is adjusted to the first target number 1. The user confirms by pressing the enter key after seeing that the random number 2 displayed on the first display area becomes the target number 1. Of course, similarly, the user may also press "%" 9 times in succession to adjust 2 to 1.

As shown in fig. 3(a) and 3(b), after receiving the confirmation instruction for the first target number 1, the hardware wallet displays a random number (assumed to be 6) to the user in the second display area. At this time, the user may continuously press "×" twice on the computer keyboard to adjust the random number 6 to the target number 8 and press the enter key for confirmation. Alternatively, the user may also adjust 6 to 8 by pressing "↓" 8 times in succession.

As shown in fig. 4(a) and 4(b), after the hardware wallet receives the confirmation instruction for the second digit target number 8, it continues to display a random number (assumed to be 4 here) to the user on the third display area. At this time, the user can continuously press "↓" 4 times on the computer keyboard to adjust the random number 4 to the target number 0 and press the enter key for confirmation. Alternatively, the user may continuously press "×" 6 times to adjust 4 to 0.

As shown in fig. 5(a) and 5(b), the random number 7 displayed on the fourth display area is adjusted to the target number 5, the random number 3 displayed on the fifth display area is adjusted to the target number 3 (since both the random number displayed on the fifth display area and the fifth target number are 3, the user can directly input a confirmation instruction without adjustment), and the random number 9 displayed on the sixth display area is adjusted to the target number 1, in this order. To this end, the hardware wallet obtains the 6 target digits in the authentication code entered by the user.

In this embodiment, the user may input the confirmation instruction by pressing the enter key, but the embodiment of the present application is not limited thereto. For example, the user may also input the confirmation instruction by stopping inputting the adjustment instruction for a fixed time period (e.g., 2 seconds or 3 seconds), and if the hardware wallet does not receive the adjustment instruction input by the user within the fixed time period, the currently displayed character on the default display area is the target character input by the user, and after the user has adjusted all the N-bit random numbers, the user may input an instruction for confirmation to the transaction device.

Optionally, if the user finds that a certain number displayed on the hardware wallet is adjusted incorrectly, the user may delete the certain number through the delete key and input the certain number again in the manner described above. Alternatively, the user may delete the last character currently displayed each time the user presses the delete key.

Above, taking numbers as an example, if the verification code includes 6-digit letters, the random letters displayed in each display area can also be adjusted according to the alphabetical order in this way.

Alternatively, if the verification code includes a combination of numbers and letters, the user can also switch numbers/letters by a specific key on the computer keyboard. For example, assuming that the verification code is 123ABC, after the user adjusts the random number displayed on the third display area to the target number 3 according to the arabic number order, the user can input a switching instruction to the transaction device through the specific key, and after receiving the switching instruction, the hardware wallet displays a random letter instead of the random number on the fourth display area, so that the user can adjust the random letter displayed on the fourth display area according to the letter order to obtain the target letter a.

The above describes a way to input the verification code to the hardware wallet, that is, after the character displayed on the display area corresponding to the i-1 th target character in the N-bit target characters is adjusted to the i-1 th target character, the hardware wallet displays a random character to the user on the display area corresponding to the i-th target character. That is, after the hardware wallet confirms that the user has adjusted one random number, the hardware wallet displays the next random number to the user. Alternatively, however, at 110, the hardware wallet may simultaneously display N random characters on N display areas corresponding to the N-bit target characters, respectively.

For example, assume that the verification code includes 6 target digits, respectively 180531. The hardware wallet may simultaneously display six random numbers on six display areas shown in fig. 2, for example, 264739 for the six random numbers displayed simultaneously. The user may adjust the random number displayed on each display area to the corresponding target number in any of the manners described above, and instruct the hardware wallet through a confirmation instruction to complete the input of the verification code. In this embodiment, the order in which the user adjusts each digit of the random number is not limited, and for example, the user may adjust 180531 displayed to 264739 in order from front to back, or may adjust the digits in order from back to front or in a random order.

It can be seen that, by using the input method according to the embodiment of the application, even if a hacker monitors an input keyboard of a computer or a mobile phone and knows how many times "↓" or "↓" the user has pressed, since the hacker does not know how many random numbers displayed by a hardware wallet, it is not possible to infer the adjusted target character, and thus it is not possible to obtain the verification code. Because the verification code is always positioned in the hardware wallet and cannot be leaked to a computer or a mobile phone, the verification code cannot be leaked due to the fact that the computer or the mobile phone is monitored, and the safety of inputting the verification code is greatly improved.

It should be noted that, without conflict, the embodiments and/or technical features in the embodiments described in the present application may be arbitrarily combined with each other, and the technical solutions obtained after the combination also fall within the protection scope of the present application.

It should be understood that, in the various embodiments of the present application, the sequence numbers of the above-mentioned processes do not mean the execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.

The transaction method according to the embodiment of the present application is described above in detail, and the device according to the embodiment of the present application will be described below with reference to fig. 6 to 11, and the technical features described in the embodiment of the method are applicable to the following embodiments of the device.

Even if the transaction device is monitored by a hacker, the hacker cannot deduce the verification code because the hacker does not know the random number generated by the hardware wallet, so that the purpose that the verification code cannot depart from the hardware wallet is realized through the combination of the transaction device and the hardware wallet, and the input security of the verification code is improved.

Optionally, the display unit is specifically configured to: and when the character displayed on the display area corresponding to the (i-1) th target character in the N-bit target characters is adjusted to be the (i-1) th target character, displaying the random character to a user on the display area corresponding to the (i) th target character.
