Abstract

A computer-implemented method includes producing medical information that characterizes a group of individuals from a set of private data representing pre or post-encounter characteristics of the individuals, wherein the individuals have had encounters with a healthcare facility. The identity of the individuals is unattainable from the produced medical information. The method also includes providing the produced medical information to report the pre or post-encounter characteristics of the group.

Claims

1. A computer-implemented method comprising:

receiving a request from a user device for medical information that characterizes a group of individuals composed of multiple individuals from a set of de-identified medical data representing pre- or post-encounter characteristics of the individuals;

producing, by a hardware processor, tokens, wherein the identity of the individuals is unattainable from the tokens, each token being associated with an individual in the group, each token associable with a corresponding token in the set of de-identified medical data, and each token in the set of de-identified medical data being associated with medical data for a corresponding individual;

producing the requested medical information that characterizes the group of individuals by identifying the tokens in the set of de-identified medical data and the associated de-identified medical data that correspond to the produced tokens, wherein the produced medical information is absent personally identifiable information and has been produced without the individuals in the group having authorized production of such medical information that characterizes the group; and

providing the produced medical information to report the characteristics of the group of individuals absent authorization from the individuals in the group of individuals.

2. The computer-implemented method of claim 1, in which producing the token for each individual includes encrypting respective data that identifies each individual.

3. The computer-implemented method of claim 1, in which producing the requested medical information that characterizes the group includes comparing the produced token for each individual in the group to the tokens associated with the set of medical data.

4. The computer-implemented method of claim 3, in which the tokens associated with the set of medical information and the produced token for each individual in the group are similarly encrypted.

5. The computer-implemented method of claim 3, in which producing the requested medical information that characterizes the group includes determining if the comparison provides at least a minimum number of matches.

6. The computer-implemented method of claim 1, in which producing the requested medical information that characterizes the group includes requesting a predefined portion of the medical information.

7. The computer-implemented method of claim 1, in which producing the requested medical information that characterizes the group includes determining if the group includes at least a minimum number of individuals.

8. The computer-implemented method of claim 1, in which the de-identified medical data is obtained from pharmacies.

9. The computer-implemented method of claim 1, wherein the produced medical information to report the characteristics of the group of individuals is provided absent authorization at any time from the individuals in the group of individuals.

10. The computer-implemented method of claim 1, wherein the medical information provided absent authorization from the group of individuals is in conformity with the Health Insurance Portability and Accountability Act (HIPAA).

11. A system comprising:

a hardware encryption server for producing a token for each individual included in a group composed of multiple individuals identified in a request received from a user device for medical information that characterizes the group absent authorization from the group of individuals wherein the identity of the individuals in the group is unattainable from the tokens; and

a data server for producing the requested medical information that characterizes the group from a set of de-identified medical data representing pre or post-encounter characteristics of the individuals by identifying tokens in the set of de-identified medical data and the associated de-identified medical data that correspond to the produced tokens, wherein an identity of each of the individuals is unattainable from the produced medical information, and the data server is configured to provide the produced medical information to report characteristics of the group of individuals absent authorization from individuals in the group of individuals.

12. The system of claim 11, in which the produced token for each individual represents encrypted data that identifies the corresponding individual.

13. The system of claim 11, in which the data server is configured to compare the produced token for each individual in the group to the tokens associated with the set of medical data.

14. The system of claim 13, in which the tokens associated with the set of medical information and the produced token for each individual in the group are similarly encrypted.

15. The system of claim 13, in which the data server is configured to determine if the comparison provides at least a minimum number of matches.

16. The system of claim 11, in which the request represents a predefined portion of information to use for producing the medical information that characterizes the group.

17. The system of claim 11, in which the encryption server is configured to determine if the group includes at least a minimum number of individuals.

18. The system of claim 11, in which the de-identified medical data is obtained from pharmacies.

19. One or more computer readable storage devices storing instructions that are executable by a processing device, and upon such execution cause the processing device to perform operations comprising:

receiving a request from a user device for medical information that characterizes a group of individuals composed of multiple individuals from a set of de-identified medical data representing pre- or post-encounter characteristics of the individuals;

producing, by a hardware processor, tokens, wherein the identity of the individuals is unattainable from the tokens, each token being associated with an individual in the group, each token associable with a corresponding token in the set of de-identified medical data, and each token in the set of de-identified medical data being associated with de-identified medical data for a corresponding individual;

producing the requested medical information that characterizes the group of individuals by identifying the tokens in the set of de-identified medical data and the associated de-identified medical data that correspond to the produced tokens, wherein the produced medical information is absent personally identifiable information and has been produced without the individuals in the group having authorized production of such medical information that characterizes the group; and

providing the produced medical information to report the characteristics of the group of individuals absent authorization from the individuals in the group of individuals.

20. The one or more computer readable storage devices of claim 19, in which producing the request token for each individual includes encrypting respective data that identifies each individual.

21. The one or more computer readable storage devices of claim 19, in which producing the requested medical information that characterizes the group includes comparing the request token for each individual in the group to the tokens associated with the set of medical information data.

22. The one or more computer readable storage devices of claim 21, in which the tokens associated with the set of medical information and the produced token for each individual in the group are similarly encrypted.

23. The one or more computer readable storage devices of claim 21, in which producing medical information that characterizes the group includes determining if the comparison provides at least a minimum number of matches.

24. The one or more computer readable storage devices of claim 19, in which producing medical information that characterizes the group includes requesting a predefined portion of the information.

25. The one or more computer readable storage devices of claim 19, in which producing medical information that characterizes the group includes determining if the group includes at least a minimum number of individuals.

26. The computer readable storage devices of claim 19, in which the de-identified medical data is obtained from pharmacies.
