detecting, via one or more sensors, a movement of the POS device, one or more movement patterns of the at least one user while entering the sensitive data, or a combination thereof;

instructing, by a secure application, a phone speaker to generate noise data for a predetermined time period, wherein sound waves from the noise data causes the POS device to vibrate, and wherein the vibration causes a noisy sensor readings; and

transmitting, by the secure application, the noisy sensor readings to the rogue application configured to determine the sensitive data using the one or more sensors of the POS device.

12. The system of claim 11 , further comprising:

altering, by the secure application, a sensor readings of the movement of the POS device, the one or more movement patterns of the at least one user, or a combination thereof,

wherein the altering includes turning off the one or more sensors, disabling a transmission of the sensor readings, or a combination thereof.

13. The system of claim 12 , wherein the altering of the sensor readings further comprising:

transmitting, by the secure application, one or more signals to the one or more sensors to add noise to the sensor reading and causing the one or more sensors to generate false readings; and

transmitting, by the secure application, the false readings to the rogue application.

14. The system of claim 13 , further comprising:

detecting, by the secure application, a conclusion of the sensitive data entry by the at least one user; and

instructing, by the secure application, to the one or more sensors to resume regular measurements.

15. The system of claim 11 , further comprising:

detecting, by the secure application, a conclusion of the sensitive data entry by the at least one user; and
