Magic dynamic password input device and method thereof

The invention relates to a password input device and a method thereof, in particular to a magic dynamic password input device capable of dynamically changing a password input position and having better security function, and a password input method thereof.

With the advent of the digital age, people are becoming more and more dependent on digital information. Not only are individual documents, photos, videos, and even personal wealth, but also important assets, all of which have entered the stage of comprehensive digitalization, digitalization. In addition to the benefits of convenient transmission, storage or processing, the information can also enable digital information to have more oriented functions and development applications in response to different digital devices. For example, the financial PIN keyboard commonly used in the financial industry is used. One of the devices for processing digital information.

Referring to FIG. 1 , a financial PIN pad, which is commonly used in the prior art, includes: a plurality of cipher keys 10, a acknowledgment key 11, a cancel key 12, and a clear key 13, wherein each cipher key 10 is used separately. For the user to input a character, and the plurality of password keys 10 are arranged on the surface of the financial password keyboard in the order of characters and fixed positions, the confirmation key 11 is used for the user to confirm the currently input password, and the cancel key 12 is used. For the user to cancel the current operation, the clear key 13 is used for the user to correct the currently input password; when using the aforementioned financial password keyboard, the plural password characters are input by the multiplexed cipher key 10 according to the individual needs of the user. A password is formed, and the clear key 13 can be used as a correction of the input error character during the input process. When the user inputs the password and confirms that the password is correct, the confirmation key 11 can be pressed to make the currently input plural character. The password is transmitted to any compatible device, and if the user wants to cancel the operation (such as canceling the transaction, etc.), the cancel button 12 can be used to achieve.

However, the aforementioned financial PIN pad is sequentially and fixed due to its plural cipher key 10 The arrangement of the positions, so if the interested person has known in advance the order and fixed position of the plurality of cipher keys 10 of the financial PIN pad, the user can press the position of the cipher key 10 to learn the plural characters of the cipher key. Therefore, the financial password keyboard has the risk of being easily stolen.

Therefore, it is proposed that the device has the feature of increasing the difficulty of stealing the password by the user's operation, and it is a technical problem that various circles are currently trying to solve.

In view of the above-mentioned shortcomings of the prior art, the main object of the present invention is to provide a magic dynamic password input device and a method thereof, which dynamically change the password input position dynamically and randomly, and increase the relying on the button position to memorize the viewer. The difficulty of the password has a better anti-peep effect.

In order to achieve the foregoing and other objects, the magic dynamic password input device of the present invention comprises: a control unit for controlling the operation of the magic dynamic password input device; and a plurality of keys having complex dynamic characters and displayed on a touch panel. a touch unit connected to the control unit for sensing the pressure of the plurality of keys; a display unit connected to the control unit for displaying the plurality of dynamic characters, wherein when the display unit displays a When the plurality of dynamic characters are set on the touch panel and the touch unit senses the pressure of one of the plurality of keys, the display unit automatically displays another set of the plurality of dynamic characters on the touch panel; And a temporary storage unit, which temporarily stores a password input.

Preferably, the complex dynamic character comprises a number of randomly arranged 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9.

Preferably, the reset button includes a confirmation button and a delete button, wherein the confirmation button is connected to the control unit and the temporary storage unit, and confirms that the input of the password is completed; the delete button is connected to the control unit and the temporary storage Unit, delete the input of the password.

Preferably, the control unit is at least one of a microprocessor, a central processing unit and a processing circuit, and the touch unit is a touch screen controller and/or a touch sensing controller, and the display The unit is a liquid crystal display module.

Preferably, the complex includes a transmission unit, wherein when the confirmation button is pressed, the borrowing The password temporarily stored in the temporary storage unit is transmitted by the transmission unit to a compatible device.

Preferably, the transmission unit is at least one of an electrical connection line and a wireless transmission module.

When the invention is initially used, the control unit causes the display unit to display a random set of a plurality of dynamic characters. When the user presses any key according to the character of the personal required password, the touch unit senses one of the plurality of keys. The pressure of the key, the display unit will automatically display another set of the plural dynamic characters on the touch panel until the user inputs all the required characters.

Thereby, the display unit automatically displays another set of the plural dynamic characters each time the button is pressed, for the person who wants to pry the user to press the position to steal the password, because the complex dynamic characters follow The user inputs each character and is in a state of constant change, thereby increasing the difficulty of relieving the pressing position to crack the password, so the present invention has a better anti-peep effect.

In order to achieve the foregoing and other objects, the magic dynamic password input method of the present invention includes: a first step of displaying a set of complex dynamic characters by a display unit; and a second step of determining whether to sense on a touch panel. The pressure of one of the plurality of keys, if yes, automatically displaying another set of the complex dynamic characters on the touch panel, and continuing to the next step; if not, repeating the second step; a third step, Determine whether to press a delete button, if yes, delete a password and repeat the second step, if not, proceed to the next step; and a fourth step, determine whether to press a confirm button, and if so, confirm The input and end of the password are completed, and if not, the first step is repeated.

Preferably, the complex dynamic character comprises a number of randomly arranged 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9.

Preferably, the multiplexing comprises temporarily transmitting the password temporarily stored in a temporary storage unit to a compatible device by using a transmission unit.

Preferably, the transmission unit is at least one of an electrical connection line and a wireless transmission module.
