Abstract
A method for entering secure data at an input device includes displaying a graphical input region having input elements, such as a number keypad, and receiving selections of the input elements via a display selection device, such as a mouse or touch screen. An attribute of the displayed graphical input region is changed so that inputs by the display selection device change for the same data input. Examples include changing the position, size and/or layout of the input elements and/or graphical input region. The graphical input elements may instead be provided with two characters so that typing one character results in input of the corresponding character, and then changing the association of the characters on the displayed input elements.
Claims17
A method for receiving secure data at an input device having a display, comprising the steps of:
- displaying data entry elements on the display of the input device, respective ones of the data entry elements being displayed at a first selection position;
- receiving a selection of a data entry element at the first selection position via a display element selecting device, said selection corresponding to data input of one or more alphanumeric characters of a character sequence of the secure data;
- automatically changing a display attribute of the data entry elements shown on the display, the changed display attribute including displaying at least one of the data entry elements at a second selection position on the display, said second selection position being at a different position on the display than the first selection position;
- and
- receiving a selection of a data entry element with the changed display attribute at the second selection position, said selection corresponding to data input of one or more alphanumeric characters as subsequent characters of the character sequence of the secure data.
A method of receiving secure data at an input device having a display, comprising the steps of:
- displaying a data entry region on the display of the input device, said data entry region including data entry elements, the data entry region and data entry elements being displayed according to a first display attribute;
- receiving a selection of one or more of said data entry elements via a display element selecting device, said selection corresponding to data input of one or more alphanumeric characters of the secure data;
- upon receiving a predetermined sequence of alphanumeric characters as data input in said receiving step, automatically changing the display attribute of at least one of said data entry region and said data entry elements to a second display attribute, said step of automatically changing the display attribute changes at least one of the attributes selected from the group consisting of:
- position of the data entry region, size of the data entry region, layout of the data entry region, and position of the data entry elements within the data entry region;
- and
- receiving a further selection of one or more of said data entry elements via a display element selecting device, said selection corresponding to data input of one or more further alphanumeric characters of the secure data.
A method of entry of secure data at an input device having a display, comprising the steps of:
- displaying data entry elements on the display, the data entry elements being labeled with first alphanumeric characters and being labeled with corresponding second alphanumeric characters;
- receiving a selection via a keyboard of a first alphanumeric character data element, said selection being received by the input device as a corresponding second alphanumeric character;
- automatically changing the displayed data entry elements on the display so that the data entry elements labeled with the second alphanumeric characters are provided with different corresponding first alphanumeric characters;
- and
- receiving a selection via the keyboard of the different first alphanumeric character as a corresponding second alphanumeric character.
A system including a computer having a computer readable media containing a computer program which when operating on the computer performs a method comprising the steps of:
- displaying data entry elements on the display of the input device;
- receiving a selection of a data entry element via a display element selecting device, said selection corresponding to data input of one or more alphanumeric characters;
- automatically changing a display attribute of the data entry elements shown on the display, said display attribute including a selection position of at least one of the data entry elements;
- and
- receiving a selection of a data entry element with the changed display attribute, said selection corresponding to data input of one or more alphanumeric characters.
