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.
Claims15
A computer-implemented method comprising:
- receiving, at an encryption server, a request from a user device for medical information that characterizes a first group composed of multiple individuals, wherein at least one of the multiple individuals has not authorized provision of personal medical information at any time;
- determining that the first group comprises at least a defined minimum number of individuals;
- subsequent to determining that the first group comprises at least the defined minimum number of individuals, producing, by a processor of the encryption server, one or more request tokens from a first set of personally identifiable information associated with the multiple individuals, wherein the first set of personally identifiable information is provided in the request and wherein each of the one or more request tokens is unique to a corresponding individual of the multiple individuals;
- comparing the request tokens to tokens generated independently of the request tokens to find matching tokens,
- wherein the independently generated tokens are generated from a second set of personally identifiable information associated with a second group of individuals, each of the independently generated tokens being unique to a corresponding individual from the second group and associated with de-identified medical information about the corresponding individual from the second group, the de-identified medical information representing pre- or post-encounter characteristics of the corresponding individual from the second group, and
- wherein at least a portion of the independently generated tokens match at least a portion of the request tokens if the portion of the independently generated tokens and the portion of the request tokens correspond to the same individuals;
- determining that at least a defined minimum number of matches have been found;
- subsequent to determining that at least the defined minimum number of matches have been found, producing the de-identified medical information associated with the independently generated tokens that were matched to the request tokens;
- and
- providing the produced de-identified medical information to report characteristics of the first group.

A system comprising:
- a computing device comprising:
- a memory configured to store instructions;
- and
- a processor to execute the instructions to perform operations comprising:
- receiving a request from a user device for medical information that characterizes a first group composed of multiple individuals, wherein at least one of the multiple individuals has not authorized provision of personal medical information at any time;
- determining that the first group comprises at least a defined minimum number of individuals;
- subsequent to determining that the first group comprises at least the defined minimum number of individuals, producing one or more request tokens from a first set of personally identifiable information associated with the multiple individuals, wherein the first set of personally identifiable information is provided in the request and wherein each of the one or more request tokens is unique to a corresponding individual of the multiple individuals;
- comparing the request tokens to tokens generated independently of the request tokens to find matching tokens,
- wherein the independently generated tokens are generated from a second set of personally identifiable information associated with a second group of individuals, each of the independently generated tokens being unique to a corresponding individual from the second group and associated with de-identified medical information about the corresponding individual from the second group, the de-identified medical information representing pre- or post-encounter characteristics of the corresponding individual from the second group, and
- wherein at least a portion of the independently generated tokens match at least a portion of the request tokens if the portion of the independently generated tokens and the portion of the request tokens correspond to the same individuals;
- determining that at least a defined minimum number of matches have been found;
- subsequent to determining that at least the defined minimum number of matches have been found, producing the de-identified medical information associated with the independently generated tokens that were matched to the request tokens;
- and
- providing the produced de-identified medical information to report characteristics of the first group.

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, at an encryption server, a request from a user device for medical information that characterizes a first group composed of multiple individuals, wherein at least one of the multiple individuals has not authorized provision of personal medical information at any time;
- determining that the first group comprises at least a defined minimum number of individuals;
- subsequent to determining that the first group comprises at least the defined minimum number of individuals, producing, by a processor of the encryption server, one or more request tokens from a first set of personally identifiable information associated with the multiple individuals, wherein the first set of personally identifiable information is provided in the request and wherein each of the one or more request tokens is unique to a corresponding individual of the multiple individuals;
- comparing the request tokens to tokens generated independently of the request tokens to find matching tokens,
- wherein the independently generated tokens are generated from a second set of personally identifiable information associated with a second group of individuals, each of the independently generated tokens being unique to a corresponding individual from the second group and associated with de-identified medical information about the corresponding individual from the second group, the de-identified medical information representing pre- or post-encounter characteristics of the corresponding individual from the second group, and
- wherein at least a portion of the independently generated tokens match at least a portion of the request tokens if the portion of the independently generated tokens and the portion of the request tokens correspond to the same individuals;
- determining that at least a defined minimum number of matches have been found;
- subsequent to determining that at least the defined minimum number of matches have been found, producing the de-identified medical information associated with the independently generated tokens that were matched to the request tokens;
- and
- providing the produced de-identified medical information to report characteristics of the first group.
