Abstract

Method and apparatus for providing authorized access to medical information concerning an individual while preserving the confidentiality of, and preventing unauthorized access to, such information. A computer database receives and stores the individual'"'"'s medical information, after the individual is tested to establish this information and the date on which such information was most recently obtained. The computer database does not contain the individual'"'"'s name, address or any other similar information by which the individual can be identified. The individual is given an identification card containing a photograph or holographic image of the individual and containing a confidential first identification number that is unique for the individual, where both the image and the first identification number are visually perceptible and cannot be altered on the card without detection of such alteration. The individual is also given a confidential second identification number that is not contained on the card and need not be unique for that individual. The computer database can be accessed telephonically, and the individual'"'"'s medical information, or a portion thereof, can be read only by an inquiror, if the inquiror or the individual first provides the individual'"'"'s first and second identification numbers. The inquiror can use the image and first identification number on the individual'"'"'s card to confirm the identity of that individual but need not be told the individual'"'"'s second identification number. After inquiror establishes the identity of the individual, the inquiror, with the assistance of the individual, can obtain a telephonic readout of the individual'"'"'s medical information.

Claims

1. A method for providing authorized access to medical information concerning an individual while preserving confidentiality of, and preventing unauthorized access to, such information, the method comprising the steps of:

storing the individual'"'"'s medical information, but not the individual'"'"'s name or address, in a computer database;

providing the individual with an identification card containing a visually perceptible image of the individual and containing a visually perceptible confidential first identification number for the individual, the image and the first identification number being unalterable on the card;

providing the individual with a confidential second identification number that is not contained on the card; and

providing telephonic access to the computer database, and allowing any inquiror to obtain a verbal readout of the individual'"'"'s medical information, or a selected portion thereof, if the inquiror or the individual first provides the individual'"'"'s first and second identification numbers, the readout of the individual'"'"'s medical information also indicating the number N of times this medical information has been read out in a selected time interval including the time of the present readout.

2. The method of claim 1, further comprising the step of indicating the most recent date of testing on which said individual'"'"'s medical information is based, as part of said readout.

3. The method of claim 2, further comprising the steps of:

determining said most recent date of testing and the number D of days that have passed since said most recent date of testing; and

if the number D exceeds a selected number D_M, advising said individual, as part of said readout, that said individual must be retested to establish a new most recent date of testing before said individual'"'"'s medical information may be subsequently read out from said database.

4. The method of claim 3, further comprising the steps of:

comparing said number N with a selected positive number N_M ; and

if said number N is larger than the number N_M, reducing said number of days D_M to a selected smaller number of days D_L.

5. The method of claim 1, wherein said first identification number is unique for that individual.

6. The method of claim 1, further comprising the step of providing said individual'"'"'s birth date on said identification card.

7. The method of claim 1, further comprising the step of providing on said individual'"'"'s identification card a telephone number to establish said telephonic access with said database.

8. The method of claim 1, further comprising the steps of:

storing said individual'"'"'s name and address at a location separate from said medical information for said individual; and

allowing access to the name and address of said individual only upon presentation of at least one of said first identification number and said second identification number.

9. The method of claim 8, further comprising the step of requiring presentation of said second identification number for access to said name and address information for said individual.

10. The method of claim 1, further comprising the step of providing a photographic image of said individual as said visually perceptible image.

11. The method of claim 1, further comprising the step of providing a holographic image of said individual as said visually perceptible image.
