    Abstract: PROBLEM TO BE SOLVED: To allow only an authorized user to input or read information by enciphering data with a random key, encoding the random key with a chip card and preserving it together with data. SOLUTION: This system is provided with a computer, reader/writer for patient card, reader/writer for user card, and user card. Patient data are preserved on the patient card or can be preserved on the other storage medium. It is suitable the patient card is the chip card having an optical mass memory. The chip controls access to data and both enciphering and deciphering functions. The random key itself is enciphered and preserved together with data. There is a dedicated record key for each patient card. The chip card preserves a generator for exchanging data between the computer and the storage medium and preparing a new cryptographic key when the computer requests the cryptographic key.

    Abstract: The present invention describes a method and system for the secure transmission and storage of protectable information, in particular, of patient information, by means of a patient card. The data stored on the patient card are protected by cryptographic methods. The data can be decrypted only with the same patient card if a doctor is authorised and the patient has given his agreement. All information which the patient card needs in order to decide whether the doctor is authorised and the key for protecting the control data and the random key are held on the chip. The patient data can be freely transmitted to any storage medium. The chip controls both the access to the data and the encryption and decryption functions. Random keys, which are themselves stored encrypted together with the data ensure that every data record remains separate from every other and that only authorised persons can access it. Every patient card has its own record key. The system and method in accordance with the invention is not directed exclusively to patient data but can be applied to any protectable data to which right of access is to be restricted.

    Abstract: PCT No. PCT/EP95/02606 Sec. 371 Date Mar. 5, 1997 Sec. 102(e) Date Mar. 5, 1997 PCT Filed Jul. 5, 1995 PCT Pub. No. WO97/02543 PCT Pub. Date Jan. 23, 1997The invention relates to communication with smart cards. Communication of any desired device with a smart card is effected by sending a message to the smart card through the device, receipt of the message by the smart card and processing of the message in accordance with one of the processes in accordance with the invention. A message arriving in a smart card is written and stored by a processor unit in a writable, non-volatile memory, such as an EEPROM, before the message is checked for authorization on the smart card by the processor unit.
