Abstract
The present disclosure introduces a new technique for hiding sensitive information in smart cards. A smartcard system relying on stegnography rather than cryptography may act as a countermeasure to prevent extraction of cryptographic information such as passwords. In one embodiment, the smart card system of the present disclosure may be used to authenticate a smart card user. A password may be stored within a hidden memory location of a smart card. A smart card may interface with an external device. Data representing the hidden memory location of the stored password may be transmitted to an external device. Access to the hidden memory location of the smart card by the external device may be allowed. The password stored within the smart card memory is compared to input data entered into the external device. If the input data matches the password stored within the smart card, a user may be authenticated.
