Abstract
An electronic device according to various embodiments of the present disclosure may include at least one sensor module including a transmitter, a receiver, a secure memory for storing data obtained by the receiver, and a security control module for controlling the transmitter based on whether a target memory in which the obtained data is to be stored is the secure memory. In an example, the sensor may be a biometric sensor in which the transmitter transits an optical signal to a user's finger or iris or the like to authenticate the user. If malicious code attempting to defeat security is detected, so that the secure memory is not set up as the target memory, the security control module may control the transmitter by restricting transmission of signals.
Claims15
An electronic device comprising:
- a display;
- at least one sensor comprising a transmitter for transmitting a signal and a receiver for receiving a response signal to the transmitted signal, wherein the at least one sensor is configured to obtain biometric data based on the response signal, wherein the obtained biometric data is compared with a pre-stored biometric data for user authentication;
- a normal memory;
- a secure memory for storing the obtained biometric data;
- and
- a security controller, connected with the at least one sensor and the secure memory, configured to:
- determine if the obtained biometric data is designated to be stored in the secure memory,
- allow the transmitter to transmit the signal the obtained biometric data is designated to be stored in the secure memory,
- prevent the transmitter from transmitting the signal if the obtained biometric data is not designated to be stored in the secure normal memory;
- and
- a controller configured to control the display to display content related to a security risk based on the determination.
A method for obtaining data using a sensor module in an electronic device, the method comprising:
- determining if an obtained biometric data from a receiver is designated to be stored in a secure memory before a transmitter transmits a signal, wherein receiver receives a response signal to a signal transmitted from a transmitter, wherein the sensor is configured to obtain the biometric data, wherein the obtained biometric data is compared with a pre-stored biometric data for user authentication;
- transmitting the signal associated with the biometric data, if the obtained biometric data is designated to be stored in the secure memory;
- preventing transmission of the signal associated with the biometric data, if the obtained biometric data is designated to be stored in a normal memory separate from the secure memory;
- and
- displaying content related to a security risk based on the determination.
A non-transitory recording medium for storing computer-readable instructions for instructing an electronic device for obtaining data using a sensor comprising a transmitter and a receiver to perform:
- determining if obtained biometric data from the receiver is designated to be stored in a secure memory before the transmitter transmits a signal, wherein receiver receives a response signal to a signal transmitted from a transmitter, wherein the sensor is configured to obtain the biometric data, wherein the obtained biometric data is compared with a pre-stored biometric data for user authentication;
- transmitting the signal associated with biometric data if the obtained biometric data received is designated to be stored in the secure memory;
- preventing transmission of the signal associated with the biometric data, if the obtained biometric data is designated to be stored in a normal memory separate from the secure memory;
- and
- displaying content related to a security risk based on the determination.
