Data interception protection
View Patent ↗A computer implemented method to protect data input to a user input device from detection, the device including an artificial haptic feedback mechanism arranged to generate an occurrence of haptic feedback for sensing by a user of the device in response to each input gesture on the device by the user, wherein at least a subset of each occurrence of haptic feedback is adjusted with respect to a previous occurrence of haptic feedback by one or more of: a timing of the haptic feedback with respect to a time of occurrence of a corresponding input gesture; an adjustment to a duration of haptic feedback relative to a duration of the previous occurrence of haptic feedback; and a generation of one or more addition occurrences of haptic feedback.
1. A computer implemented method to protect data input to a user input device from detection, the user input device including an artificial haptic feedback mechanism arranged to generate an occurrence of haptic feedback for sensing by the user of the user input device in response to each input gesture on the user input device by the user, the method comprising:
adjusting at least a subset of each occurrence of haptic feedback with respect to a previous occurrence of haptic feedback by one or more of:
a timing of the haptic feedback with respect to a time of occurrence of a corresponding input gesture including one or more of: synchronizing the haptic feedback for an input gesture with a synchronization reference other than the input gesture itself, or adding a delay between the detection of the input gesture and the generation of the haptic feedback;
an adjustment to a duration of haptic feedback relative to a duration of the previous occurrence of haptic feedback including one or more of: a prolongation of the haptic feedback for a duration exceeding the previous occurrence of haptic feedback, or a reduction in a duration of the haptic feedback to a duration below the previous occurrence of the haptic feedback; and
a generation of one or more additional occurrences of haptic feedback.
2. The method of claim 1 , wherein the user input device is a touchscreen device, each input gesture includes a swipe gesture for input of data via a soft keyboard, and the haptic feedback includes a vibration of the user input device.
3. The method of claim 1 , wherein the synchronization reference is a linear time scale.
4. The method of claim 1 , wherein the adjustment of the haptic feedback is performed responsive to a determination that an occurrence of haptic feedback and a previous occurrence of haptic feedback correspond to the same input gesture.
5. A computer system comprising:
a processor and memory storing computer program code for protecting data input to a user input device from detection, the user input device including an artificial haptic feedback mechanism arranged to generate an occurrence of haptic feedback for sensing by the user of the user input device in response to each input gesture on the user input device by the user, by:
adjusting at least a subset of each occurrence of haptic feedback with respect to a previous occurrence of haptic feedback by one or more of: a timing of the haptic feedback with respect to a time of occurrence of a corresponding input gesture including one or more of: synchronizing the haptic feedback for an input gesture with a synchronization reference other than the input gesture itself, or adding a delay between the detection of the input gesture and the generation of the haptic feedback; an adjustment to a duration of haptic feedback relative to a duration of the previous occurrence of haptic feedback including one or more of: a prolongation of the haptic feedback for a duration exceeding the previous occurrence of haptic feedback, or a reduction in a duration of the haptic feedback to a duration below the previous occurrence of the haptic feedback; and a generation of one or more addition occurrences of haptic feedback.
6. A non-transitory computer-readable storage medium storing computer program code to, when loaded into a computer system and executed thereon, cause the computer system to protect data input to a user input device from detection, the user input device including an artificial haptic feedback mechanism arranged to generate an occurrence of haptic feedback for sensing by the user of the user input device in response to each input gesture on the user input device by the user, by:
adjusting at least a subset of each occurrence of haptic feedback with respect to a previous occurrence of haptic feedback by one or more of: a timing of the haptic feedback with respect to a time of occurrence of a corresponding input gesture including one or more of: synchronizing the haptic feedback for an input gesture with a synchronization reference other than the input gesture itself, or adding a delay between the detection of the input gesture and the generation of the haptic feedback; an adjustment to a duration of haptic feedback relative to a duration of the previous occurrence of haptic feedback including one or more of: a prolongation of the haptic feedback for a duration exceeding the previous occurrence of haptic feedback, or a reduction in a duration of the haptic feedback to a duration below the previous occurrence of the haptic feedback; and a generation of one or more addition occurrences of haptic feedback.
