Abstract:
1. A chip card interface device (CCID) configured for protecting data stored at the CCID in the event of a compromise, the CCID comprising: a housing; a memory device disposed within the housing, the memory for storing data, the data comprising sensitive data and non-sensitive data, and wherein the sensitive data is stored in a sensitive data location that is separate and distinct from a non-sensitive data location in which the sensitive data is stored; a compromise detection system, the compromise detection system comprising: a data protection system coupled with the compromise detection system, the data protection system configured for: a personal identification number (PIN) entry device (PED) configured for receiving a cardholder current PIN and a cardholder desired new PIN from a cardholder; a chip card input/output device configured for communicating a verify command to a chip card of the CCID including data corresponding to the received cardholder current PIN, the chip card input/output device also configured for receiving a verification message from the chip card, wherein the chip card generates the verification message by validating the received cardholder current PIN by comparing it with the current PIN stored on the chip card; and a processing device for determining that the verification message from the chip card indicates that authentication of the cardholder current PIN was successful.
