Electronic device and method for securing user input data

摘要

An apparatus to secure input data includes a main processor to enter into a secure mode, a touch panel to detect an input, and a touch integrated circuit (IC) to obtain coordinate data of the input, and to encrypt data related to the input using a secure key, in which the data related to the input is encrypted in the secure mode, and the touch IC transmits the encrypted data to the main processor. A method for securing input data in an electronic device includes entering into a secure mode, receiving an input using a touch panel, obtaining coordinate data of the input using a touch integrated circuit (IC), and encrypting data related to the input using a secure key, in which the data related to the input is encrypted in the secure mode, and the touch IC transmits the encrypted data to the main processor.

主权项

1. An apparatus to secure input data, comprising:
a main processor to enter into a secure mode; a touch panel to receive an input; a touch integrated circuit (IC) to obtain coordinate data of the input, and to encrypt data related to the input using a secure key; and a communication module to transmit the encrypted data related to the input, wherein the data related to the input is encrypted in the secure mode, and the touch IC blocks a transfer path between the touch IC and the main processor of the electronic device such that the main processor is unaware of the input received by the touch panel during the secure mode.
