Secure data broker for sensitive data
A secure data broker includes a public network interface, an authorization module, a database interface, and an encryption module. The public network interface is configured to receive a database query and authorization information from a client device over a secure connection and return a response to the database query to the client device over the secure connection. The authorization module is configured to authorize the client device based on the authorization information, which was issued to the client device by the public safety platform. The database interface is configured to submit the database query to a secure database in response to the authorization of the client device and to receive the response to the database query from the secure database. The encryption module is configured to encrypt the response to the database query using a broker key.
1. A secure data broker, comprising:
a public network interface configured to:
receive a database query and authorization information from a client device over a secure connection, and
return a response to the database query to the client device over the secure connection;
a processor configured to execute instructions and
a set of non-transitory instructions executable by the processor for:
generating an authorization of the client device based on the authorization information, wherein a public safety platform issues the authorization information to the client device,
transmitting the authorization information to the public safety platform via the public network interface, and
receiving from the public safety platform, via the public network interface, a confirmation that a user of the client device is authorized to access the secure database via the secure data broker,
encrypt the response to the database query using a broker key; and
a database interface configured to submit the database query to a secure database in response to the authorization of the client device and to receive the response to the database query from the secure database.
2. The secure data broker of claim 1 , wherein the instructions are further executable for transmitting the encrypted response to the public safety platform for storage.
3. The secure data broker of claim 1 , wherein the public network interface is configured to connect to the client device and to the public safety platform over the Internet.
4. The secure data broker of claim 1 , wherein the public network interface is configured to perform a certificate-based mutual authentication procedure with the client device.
5. The secure data broker of claim 1 , wherein the database interface comprises a local network interface configured to connect the secure data broker to a secure data interface that is connected to the secure database over a private network.
6. The secure data broker of claim 1 , wherein the instructions are further executable for providing the encrypted response to the public safety platform for storage in a repository, wherein the public safety platform cannot decrypt data in the repository encrypted by the broker key.
7. The secure data broker of claim 6 , wherein the instructions are further executable for retrieving data stored in the repository of the public safety platform, decrypting the retrieved data using the broker key, and providing the decrypted data to an authorized user.
8. The secure data broker of claim 1 , wherein the secure data broker executes on a device located within a public safety answering point (PSAP), the secure data broker connects to the client device across a public network, and the secure data broker connects to the public safety platform across a public network.
9. The secure data broker of claim 1 , wherein the public safety platform is a cloud-based computer-aided dispatch (CAD) platform, a user of the client device is an emergency responder, and the secure database is a criminal justice information services (CJIS) database.
10. A computer-implemented method, comprising:
receiving, via a public network interface, a database query and authorization information from a client device over a secure connection, and
generating an authorization of the client device based on the authorization information, wherein a public safety platform issues the authorization information to the client device;
transmitting the authorization information to the public safety platform via the public network interface;
receiving from the public safety platform, via the public network interface, a confirmation that a user of the client device is authorized to access the secure database via the secure data broker;
submitting, with a database interface, the database query to a secure database in response to the authorization of the client device and to receive the response to the database query from the secure database;
encrypting the response to the database query using a broker key; and
returning, via the public network interface, a response to the database query to the client device over the secure connection.
11. The computer-implemented method of claim 10 , further comprising transmitting the encrypted response to the public safety platform for storage.
12. The computer-implemented method of claim 10 , wherein the public network interface is configured to connect to the client device and to the public safety platform over the Internet.
13. The computer-implemented method of claim 10 , wherein the public network interface is configured to perform a certificate-based mutual authentication procedure with the client device.
14. The computer-implemented method of claim 10 , wherein the database interface comprises a local network interface configured to connect the secure data broker to a secure data interface that is connected to the secure database over a private network.
15. The computer-implemented method of claim 10 , further comprising providing the encrypted response to the public safety platform for storage in a repository, wherein the public safety platform cannot decrypt data in the repository encrypted by the broker key.
16. The computer-implemented method of claim 15 , further comprising retrieving data stored in the repository of the public safety platform, decrypting the retrieved data using the broker key, and providing the decrypted data to an authorized user.
17. The computer-implemented method of claim 10 , wherein the secure data broker executes on a device located within a public safety answering point (PSAP), the secure data broker connects to the client device across a public network, and the secure data broker connects to the public safety platform across a public network.
18. The computer-implemented method of claim 10 , wherein the public safety platform is a cloud-based computer-aided dispatch (CAD) platform, a user of the client device is an emergency responder, and the secure database is a criminal justice information services (CJIS) database.
