Smart Card With Multilevel Data Access

    A smart card is a device that includes an embedded integrated circuit chip (ICC) that can be either a secure microcontroller or equivalent intelligence with internal memory or a memory chip alone. The card connects to a reader with direct physical contact or with a remote contactless radio frequency interface.

Smart cards are used in many applications worldwide, including:

• Secure identity applications - employee ID badges, citizen ID documents, electronic passports, driver's licenses, online authentication devices

• Healthcare applications - citizen health ID cards, physician ID cards, portable medical records cards

• Payment applications - contact and contactless credit/debit cards, transit payment cards

• Telecommunications applications - GSM Subscriber Identity Modules, pay telephone payment cards

    The smart card can also hold Sensitive Personal Information related to use of the card itself. For example in case of biometric identification cards, the biometric information is stored on the card rather than on a central remote system. This is done in order to improve the accuracy of identifying individuals ( Something you have - the card with all of its security capabilities, Something you know - a password or personal identification number (PIN), Something you are - the biometric)

    Another example where this model could be used are healthcare applications, where the nature of the information in question makes the model particularly appealing in order to preserve the privacy.

In general, when the application data is to be stored in an online database it implies that it is outside the control of the individual and the information could be captured, stolen and used against the will of the card owner.

    Smart cards offer a number of features that can be used to provide or enhance privacy protection in systems. For example:

    Authentication. Smart cards provide mechanisms for authenticating others who want to gain access to the card.

    Encryption. Smart cards provide a robust set of encryption capabilities including key generation, secure key storage, hashing and digital signing.

    Secure communications. Smart cards provide a means of secure communications between the card and card readers.
