## Abstract

Systems, methods and non-transitory computer readable media for determining permissions in privacy firewalls are provided. At least part of a content of a data collection may be analyzed to determine a subject matter. A permission corresponding to the data collection and at least one user may be determined based on the subject matter. A request of the at least one user to access at least part of the data collection may be received. In response to a first determined permission, the requested access to the at least part of the data collection may be provided, and in response to a second determined permission, the request may be denied.

## Claims

### Claim 1

A non-transitory computer readable medium storing a software program comprising data and computer implementable instructions for carrying out a method for determining permissions, the method comprising:
analyzing at least part of a content of a data collection to determine a subject matter;
determining a permission corresponding to the data collection and at least one user based on the subject matter;
receiving a request of the at least one user to access at least part of the data collection;
in response to a first determined permission, providing the requested access to the at least part of the data collection; and
in response to a second determined permission, denying the request.

### Claim 2 (depends on 1)

The non-transitory computer readable medium of claim 1, wherein receiving the request of the user comprises:
accessing a stream of digital communication data sent by a first computing device to a second computing device; and
analyzing the stream to detect the request in the stream.

### Claim 3 (depends on 2)

The non-transitory computer readable medium of claim 2, wherein the analysis of the stream is performed by the second computing device.

### Claim 4 (depends on 2)

The non-transitory computer readable medium of claim 2, wherein the analysis of the stream is performed by a third computing device.

### Claim 5 (depends on 1)

The non-transitory computer readable medium of claim 1, wherein the data collection includes a first portion and a second portion, the first portion includes identifiable information and the second portion does not include identifiable information, and the method further comprises:
in response to a third determined permission, providing access to the content of the data collection, including access to the first portion and the second portion of the data collection; and
in response to a fourth determined permission, providing partial access to the data collection, the partial access includes access to the second portion of the data collection and excludes access to the first portion of the data collection.

### Claim 6 (depends on 1)

The non-transitory computer readable medium of claim 1, wherein method further comprises, in response to a third determined permission, providing access to synthetic information based on the data collection.

### Claim 7 (depends on 1)

The non-transitory computer readable medium of claim 1, wherein the method further comprises, in response to a third determined permission, providing access to statistical information based on the data collection.

### Claim 8 (depends on 1)

The non-transitory computer readable medium of claim 1, wherein the subject matter corresponds to a body organ, and the method further comprises:
in response to a first body organ corresponding to the subject matter, determining a first permission corresponding to the data collection and the at least one user; and
in response to a second body organ corresponding to the subject matter, determining a second permission corresponding to the data collection and the at least one user, the second permission differs from the first permission.

### Claim 9 (depends on 1)

The non-transitory computer readable medium of claim 1, wherein the subject matter corresponds to a medical specialty, and the method further comprises:
in response to a first medical specialty corresponding to the subject matter, determining a first permission corresponding to the data collection and the at least one user; and
in response to a second medical specialty corresponding to the subject matter, determining a second permission corresponding to the data collection and the at least one user, the second permission differs from the first permission.

### Claim 10 (depends on 1)

The non-transitory computer readable medium of claim 1, wherein the subject matter corresponds to a disease, and the method further comprises:
in response to a first disease corresponding to the subject matter, determining a first permission corresponding to the data collection and the at least one user; and
in response to a second disease corresponding to the subject matter, determining a second permission corresponding to the data collection and the at least one user, the second permission differs from the first permission.

### Claim 11 (depends on 1)

The non-transitory computer readable medium of claim 1, wherein the at least part of the content of the data collection includes at least one or more medical images, and the method further comprises analyzing the one or more medical images to determine the subject matter.

### Claim 12 (depends on 11)

The non-transitory computer readable medium of claim 11, wherein the method further comprises:
calculating a convolution of a plurality of pixels of the one or more medical images; and
using the calculated convolution to determine the subject matter.

### Claim 13 (depends on 11)

The non-transitory computer readable medium of claim 11, wherein the method further comprises:
analyzing one or more pixels of at least one of the one or more medical images to generate a transformed image; and
using the transformed image to determine the subject matter.

### Claim 14 (depends on 1)

The non-transitory computer readable medium of claim 1, wherein the at least part of the content of the data collection includes at least textual information, and the method further comprises analyzing the textual information to determine the subject matter.

### Claim 15 (depends on 1)

The non-transitory computer readable medium of claim 1, wherein the at least part of the content of the data collection includes at least one or more audio recordings, and the method further comprises analyzing the one or more audio recordings to determine the subject matter.

### Claim 16 (depends on 1)

The non-transitory computer readable medium of claim 1, wherein the determination of the permission corresponding to the data collection and the at least one user is based on the subject matter and a property of the at least one user.

### Claim 17 (depends on 16)

The non-transitory computer readable medium of claim 16, wherein the property of the at least one user is an affiliation of the at least one user.

### Claim 18 (depends on 16)

The non-transitory computer readable medium of claim 16, wherein the property of the at least one user is a medical specialty corresponding to the at least one user.

### Claim 19

A system for determining permissions, the system comprising:
at least one processing unit configured to:
analyze at least part of a content of a data collection to determine a subject matter;
determine a permission corresponding to the data collection and at least one user based on the subject matter;
receive a request of the at least one user to access at least part of the data collection;
in response to a first determined permission, provide the requested access to the at least part of the data collection; and
in response to a second determined permission, deny the request.

### Claim 20

A method for determining permissions, the method comprising:
analyzing at least part of a content of a data collection to determine a subject matter;
determining a permission corresponding to the data collection and at least one user based on the subject matter;
receiving a request of the at least one user to access at least part of the data collection;
in response to a first determined permission, providing the requested access to the at least part of the data collection; and
in response to a second determined permission, denying the request.
