First Claim
1. A method of input of a security code by means of a touch screen of an electronic device for access to a function, apparatus or given location, wherein the touch screen comprises control keys, which can be activated by manual action of a user using a finger or a stylus, each of the keys comprises at least one sensitive pad linked to a microprocessor unit of the electronic device, wherein each key of the touch screen defines a different number, wherein the electronic device is a wrist watch comprising:
- a liquid-crystal display;
means for transmitting and/or receiving signals; and
at least one control button to actuate various functions of the watch, wherein the control keys of the touch screen are activated when the control button is pressed, and wherein the liquid-crystal display indicates different operations of entry, verification and transmission of the security code, wherein the method comprises a first series of steps in an entry mode of the security code, the first series of steps comprising;
a) placing a finger or stylus on a first key of the touch screen, wherein the first key represents a first number of the code to be entered; and
b) moving the finger or stylus on the touch screen over a specific trajectory from the first key to a second key of the touch screen, wherein the second key represents a second number of the code to be entered, and wherein the microprocessor unit registers sensitive keys or pads activated during the movement of the finger or stylus on the screen from the first key to the second key to determine the security code based on the first number entered, the second number entered and the specific trajectory of the finger or stylus on the keys activated during movement of the finger or stylus.

Abstract
The method relates to the input of a security code by means of a touch screen of an electronic device such as a watch for access to a specific function, an apparatus or a given location. This touch screen comprises control keys, which can be activated by a manual action of a user using a finger or a stylus. Each key is linked to a microprocessor unit of the electronic device. The method comprises steps which consist of placing a finger or stylus on a key of the touch screen, which represents a first reference of the code to be entered, moving the finger or stylus from the first reference to a key of a second reference over a specific trajectory through the microprocessor unit, keeping the finger on the second reference for a given period of time or detecting a change in trajectory of the finger in the area of the key of the second reference to be input, moving the finger from the key of the second reference to a key of a third reference over a specific trajectory, and removing the finger or stylus from the touch screen to validate the entered code and access to the function, apparatus or given location.

12. An electronic device comprising:
-
a touch screen with control keys, wherein the touch screen is activated by a manual action of a user using a finger or a stylus, and each of the keys comprises at least one sensitive pad connected to a microprocessor unit, wherein each key of the touch screen defines a different number for a security code to be composed, wherein the microprocessor unit is fitted to register sensitive keys or fields activated during movement of the finger or stylus on the screen from one key representing a first reference to second key representing a second reference determining a security code, wherein the electronic device operates to implement a method of input of a security code by means of the touch screen for access to a function, an apparatus or a given location, wherein the electronic device is a wrist watch comprising a liquid-crystal display;
means for transmitting and/or receiving signals; and
at least one control button to actuate various functions of the watch, wherein the control keys of the touch screen are activated when the control button is pressed, and wherein the liquid-crystal display indicates different operations of entry, verification and transmission of the security code, wherein the method comprises a series of steps in an entry mode, the series of steps comprising;a) placing a finger or stylus on a first key of the touch screen, wherein the first key represents a first number of the code to be entered; and b) moving the finger or stylus on the touch screen over a specific trajectory from the first key to a second key of the touch screen, wherein the second key represents a second number of the code to be entered, and wherein the microprocessor unit registers the sensitive keys or pads activated during the movement of the finger or stylus on the screen from the first key to the second key to determine the security code based on the first number entered, the second number entered and the specific trajectory of the finger or stylus on the keys activated during movement of the finger or stylus. - View Dependent Claims (13)
