22. A computer-implemented method for controlling the access of healthcare providers to the medical records of a patient held in a medical record database, the method including the steps of:
(a) the patient inputting access rights to be granted to one or more healthcare providers into a personal electronic device via an associated user interface;
(b) the personal electronic device generating an access authorization message which identifies the one or more healthcare providers and specifies the corresponding access rights;
(c) transmitting the access authorization message from the personal electronic device to a computer system of one of the one or more healthcare providers;
(d) transmitting the access authorization message together with a request for access to a patient’s medical records from the healthcare provider’s computer system to the medical record database;
(e) verifying that the access authorization message originated from the patient;
wherein the healthcare provider is granted access to the patient’s medical records in accordance with the access authorization message if it is verified that the access authorization message originated from the patient.
23. The method according to claim 22, wherein verifying that the access authorization message originated from the patient includes authenticating a digital signature associated with the access authorization message.
24. The method according to claim 23, wherein the digital signature is generated by a private encryption key associated with the patient and the medical record database authenticates the digital signature using a public decryption key which corresponds to the private encryption key.
25. The method according to claim 22, wherein the personal electronic device includes a private encryption key associated with the patient which is used to generate the digital signature that accompanies the access authorization message.
26. The method according to claim 22, wherein the access authorization message includes one or more of the following restrictions:
(a) a time interval during which access is authorized;
(b) a category of medical data to which access is authorized; or
(c) a type of access which is authorized.
27. The method according to claim 22, wherein the medical record database is accessible to the one or more healthcare providers over a network.
28. The method according to claim 22, wherein the personal electronic device is password protected.
29. The method according to claim 22, wherein the personal electronic device is activated using one or more forms of biometric data associated with the patient.
30. The method according to claim 22, wherein the medical record database verifies that the access authorization message originated from the patient using a password transmitted by the patient to the healthcare provider together with the access authorization message.
31. A system for controlling the access of healthcare providers to the medical records of a patient held in a medical record database, the system including:
(a) an input component for entering patient determined access rights to be granted to one or more healthcare providers;
(b) a processor for generating an access authorization message that identifies the one or more healthcare provides and specifies the corresponding access rights;
(c) a first transmitter for transmitting the access authorization message from the the processor to one or more healthcare providers;
(d) a second transmitter for transmitting the access authorization message together with a request for access to the patient’s medical records from the healthcare provider to the medical record database;
(e) a verification component for verifying the that the access authorization message originated from the patient;
wherein the healthcare provider is granted access to the patient’s medical records in accordance with the access authorization message if it is verified that the access authorization message originated from the patient whose medical records originated from the patient
32. The system according to claim 31, wherein the verification component verifies that the access authorization message originated from the patient by authenticating a digital signature associated with the access authorization message.
33. The system according to claim 31, wherein the processor is provided as part of a personal electronic device selected from one of the following:
