Distributed user data management systems with local data storage

A system comprising:

• a memory device;
• and
• a processing device coupled to the memory device, the processing device to perform operations comprising:
• receiving, at a first user data management server of a distributed user data management system, a request to enroll a first user in the distributed user data management system, wherein the request comprises an identifier of the first user, and wherein the first user data management server is associated with a first region of the distributed user data management system;
• determining an anonymous representation of the first user based at least on the identifier of the first user and a one-way function;
• storing, in a first mapping store of the first user data management server, a mapping of the anonymous representation of the first user to the first region;
• receiving, from a second user data management server of the distributed user data management system, an indication to synchronize the first mapping store with a second mapping store of the second user data management server, the indication comprising a mapping of an anonymous representation of a second user to a second region of the distributed user data management system;
• receiving, at the first user data management server, a second request directed to data of the second user, wherein the second request comprises an identifier of the second user, and wherein the data of the second user is stored at the second user data management server in accordance with a data use policy associated with the second region;
• and
• synchronizing the first mapping store with the second mapping store by adding, to the first mapping store, the mapping of the anonymous representation of the second user to the second region of the distributed user data management system.

A non-transitory computer-readable medium comprising instructions that, when executed by a processing device, cause the processing device to perform operations comprising:

• receiving, at a first user data management server of a distributed user data management system, a request to enroll a first user in the distributed user data management system, wherein the request comprises an identifier of the first user, and wherein the first user data management server is associated with a first region of the distributed user data management system;
• determining an anonymous representation of the first user based at least on the identifier of the first user and a one-way function;
• storing, in a first mapping store of the first user data management server, a mapping of the anonymous representation of the first user to the first region;
• receiving, from a second user data management server of the distributed user data management system, an indication to synchronize the first mapping store with a second mapping store of the second user data management server, the indication comprising a mapping of an anonymous representation of a second user to a second region of the distributed user data management system;
• receiving, at the first user data management server, a second request directed to data of the second user, wherein the second request comprises an identifier of the second user, and wherein the data of the second user is stored at the second user data management server in accordance with a data use policy associated with the second region;
• and
• synchronizing the first mapping store with the second mapping store by adding, to the first mapping store, the mapping of the anonymous representation of the second user to the second region of the distributed user data management system.
