Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for generating surrogate user identifiers. In one aspect, a method includes receiving, by a surrogate identifier (ID) system, encrypted user data for a requesting entity. A surrogate ID generator running in a first trusted execution environment (TEE) of the surrogate ID system obtains, from multiple key coordinators, respective parts of a first key and respective parts of a second key. The first key is generated using the respective parts of the first key received from the multiple key coordinators. The second key is generated using the respective parts of the second key received from the multiple key coordinators. The surrogate ID generator decrypts the encrypted user data using the first key to obtain user data in cleartext. The surrogate ID generator generates a surrogate ID using the user data and the second key.
