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: EEPROM data files are managed in order to restore data after abortion of a write operation, where data is stored in a record-oriented data structure with each of the records containing a status byte along with the data contents. All of the data files affected by the write operation contain either all of the data stored prior to the write operation, or all of the data as modified subsequent to the write operation. Each file is retained as active data, in case of a power failure, until all files have been successfully updated according to write operation. Independent claims are included for; (a) a system for managing EEPROM data files; and (b) a computer program product

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.

Abstract: A message received by a processor card (10) is written by a processor unit (30) into a writable, non-volatile memory (60), such as an EEPROM (60) and stored therein before its right of access to the processor card (10) is checked by the processor unit (30). As the storage locations in the writable, non-volatile memory (60) have a freely definable data size, within the limits of the total data size of the writable, non-volatile memory (60), messages containing data of whatever length may be checked for right of access and processed. Messages received from the outside by the processor card (10) may be either directly or indirectly stored in the non-volatile memory (60), for example after being first stored in the writable, volatile buffer memory (40) and if required pre-processed. Pre-processing may for example consist in determining the address of the storage location in which the message should be processed. Since the right of access for writing into the writable, non volatile memory (60) must first be checked before the message is further processed, storage in the writable, non-volatile memory (60) is a temporary storage and its final memory location is not yet determined. The invention is useful for communications by means of processor cards. For a device of whatever type to communicate with a processor card, the device sends a message to the processor card, the message is received by the processor card (10) and processed according to the disclosed process.
