METHOD OF PREVENTING USER INFORMATION FROM HACKING IN AN ATM WITH EPP INTEGRATED TOUCHSCREEN

摘要

PURPOSE: A customer information method for preventing hacker's access of the automatic teller machine equipped with EPP integrated touch screen fundamentally can block the information reveal [customer data leakage] of client with the illegal hacking. CONSTITUTION: A transaction screen data necessary for the financial transaction progressing in the touch screen the main CPU controls the transaction screen (S110) is provided. The touch coordinates input zone information is provided to the screen indicated according to transactions screen data on the touch screen to the security CPU (S120) (S130). Client uses the automatic teller machine for the touch screen with the display of the transaction screen (S140). The touch screen senses the input if the client inputs the information by the touch screen phase (S150). Touch coordinate data in which the security CPU is inputted by the client is received (S160). It analyzes whether it is not whether touch coordinate data in which the security CPU is inputted by the client to the picture of touch screen is the coordinate within the range of the pre-set touch coordinates input area or not or not (S170). In case touch coordinates data which the client inputs belongs within the range of the pre-set touch coordinates input area the security CPU transmits corresponding touch coordinate data with the main CPU (S180). Touch coordinate data which the main CPU is transmitted from the security CPU is input and the financial transaction is performed (S190).
