Abstract
A secure method, apparatus or computer program incorporates a method for entering private information such as a user identifier, password or other secret code comprising at least one symbol or character. According to method in one illustrated embodiment, the user selects characters for input starting from presentation of an initial suggested character, moving under user control to presentation of a user's desired input character, and then followed by the selection by the user of that presented character as a character for data input. The method includes randomizing the timing of the display and/or reaction time to user input so that the number and timing of the key presses required to select any specific desired character for input is made unpredictable. This makes it difficult during entry of information to determine by covert means what specific information is being entered.
