Abstract

Disclosed herein are systems and methods for setting, accessing, and modifying user privacy settings using a distributed ledger. In an aspect, a system can search previously stored software contracts to locate an up-to-date version of a software contract associated with a user based on a request for access to user data for the particular user. Then, the system determines that the user data is permitted to be shared. The system transmits, to a data virtualization platform, instructions to extract encrypted user data from a data platform. The system can then make available, to a data verification system, a private encryption key and details associated with the software contract to verify that the private encryption key and the user data match. Then the system transmits, to the data virtualization platform, the private encryption key so that the data virtualization platform can decrypt the encrypted user data.

First claim

What is claimed is:

1. A user device comprising:
one or more computer readable storage devices configured to store computer executable instructions;
a head mounted display;
sensors configured to detect surroundings of the user device;
a network interface; and
one or more hardware computer processors in communication with the one or more computer readable storage devices to execute the computer executable instructions to cause the user device to:
receive privacy settings associated with a first user;
transmit, to a distributed ledger manager via the network interface, the privacy settings for storage on a distributed ledger, wherein the distributed ledger manager comprises a distributed ledger and software configured to read and write to the distributed ledger;
receive, from the distributed ledger manager via the network interface, a first public encryption key associated with the first user;
collect, via the sensors, environment data associated with the user device, wherein the sensors are configured to detect surroundings of the user device;
encrypt the environment data based on the first public encryption key;
semantically tag the encrypted environment data with metadata, wherein the metadata indicates at least identifying information about the user device; and
transmit, to a data platform via the network interface, the semantically tagged encrypted environment data, wherein the data platform comprises one or more databases.

2. The user device of claim 1 , wherein an operator of the data platform will not have direct access to the environment data because the operator does not have an appropriate key to decrypt the environment data.

3. The user device of claim 1 , wherein the first public encryption key is generated by the distributed ledger manager based at least in part on the privacy settings.

4. The user device of claim 1 , wherein the sensors include one or more of: an accelerometer, a camera, and a GPS sensor.

5. The user device of claim 1 , wherein the metadata is not encrypted.

6. A user device comprising:
one or more computer readable storage devices configured to store computer executable instructions;
a head mounted display; and
one or more hardware computer processors in communication with the one or more computer readable storage devices to execute the computer executable instructions to cause the user device to:
receive privacy settings associated with a first user;
transmit, to a distributed ledger manager, the privacy settings;
receive, from the distributed ledger manager, a first public encryption key associated with the first user;
collect, via one or more sensors, environment data associated with the user device;
encrypt the environment data based on the first public encryption key;
semantically tag the encrypted environment data with metadata, wherein the metadata indicates at least identifying information about the user device; and
transmit, to a data platform, the semantically tagged encrypted environment data.

7. The user device of claim 6 , wherein the public encryption key is generated by the distributed ledger manager based at least in part on the privacy settings.

8. The user device of claim 6 , wherein the one or more sensors are configured to detect surroundings of the user device.

9. The user device of claim 6 , wherein the one or more sensors include one or more of: an accelerometer, a camera, and a GPS sensor.

10. The user device of claim 6 , wherein the metadata is not encrypted.

11. The user device of claim 6 , wherein the distributed ledger manager comprises a distributed ledger and software configured to read and write to the distributed ledger.

12. The user device of claim 6 , wherein the data platform comprises one or more databases.

13. The user device of claim 6 , wherein an operator of the data platform does not have an appropriate key to decrypt the environment data.

14. A method comprising:
receiving privacy settings associated with a first user;
transmitting, to a distributed ledger manager, the privacy settings;
receiving, from the distributed ledger manager, a first public encryption key associated with the first user;
collecting, via one or more sensors, environment data associated with a user device;
encrypting the environment data based on the first public encryption key;
semantically tagging the encrypted environment data with metadata, wherein the metadata indicates at least identifying information about the user device; and
transmitting, to a data platform, the semantically tagged encrypted environment data, wherein the data platform comprises one or more databases.

15. The method of claim 14 , wherein the public encryption key is generated by the distributed ledger manager based at least in part on the privacy settings.

16. The method of claim 14 , wherein the one or more sensors are configured to detect surroundings of the user device.

17. The method of claim 14 , wherein the one or more sensors include one or more of: an accelerometer, a camera, and a GPS sensor.

18. The method of claim 14 , wherein the metadata is not encrypted.

19. The method of claim 14 , wherein the distributed ledger manager comprises a distributed ledger and software configured to read and write to the distributed ledger.

20. The method of claim 14 , wherein an operator of the data platform does not have an appropriate key to decrypt the environment data.
