Abstract
Aspects of the technology provide an electronic device having a touch display and a method of detecting any possible tampering with the electronic device using the same ITO traces of a conductive grid of the touch display that are used to drive the touch display for displaying information and/or sensing touch inputs.
Claims20
A non-transitory computer-readable medium comprising computer-readable instructions, which when executed by at least one processor, cause the at least one processor to:
- perform a touch scan of a first portion of conductive lines on a touch screen to detect a touch;
- and
- perform a security scan of a second portion of the conductive lines on the touch screen to detect a tamper event.
A system for tamper detection of a touch screen, the system comprising:
- a collection of conductive lines on the touch screen;
- a touch controller connected to the conductive lines and configured to detect a touch event;
- and
- a tamper controller connected to the conductive lines and configured to detect a tamper event at least one processor.

A device comprising:
- at least one processor;
- and
- memory configured to store computer-readable instructions, which when executed by the at least one processor, cause the at least one processor to:
- perform a touch scan of a first portion of conductive lines on a touch screen to detect a touch;
- and
- perform a security scan of a second portion of the conductive lines on the touch screen to detect a tamper event.
