Private-ID is a collection of algorithms to match records between two parties, while preserving the privacy of these records. We present two algorithms to do this---one of which does an outer join between parties and another does a inner join and then generates additive shares that can then be input to a Multi Party Compute system like CrypTen. Please refer to our paper for more details.
Private-ID is implemented in Rust to take advantage of the languages security features and to leverage the encryption libraries that we depend on. It should compile with the nightly Rust toolchain.
The following should build and run the unit tests for the building blocks used by the protocols
cargo build
,cargo test
Each protocol involves two parties and they have to be run in its own shell environment. We call one party Company and another party Partner.
This protocol maps the email addresses from both parties to a single ID spine, so that same e-mail addresses map to the same key.
To run Company
env RUST_LOG=info cargo run --bin private-id-server -- \
--host 0.0.0.0:10009 \
--input etc/example/email_company.csv \
--stdout \
--tls-dir etc/example/dummy_certs
To run Partner
env RUST_LOG=info cargo run --bin private-id-client -- \
--company localhost:10009 \
--input etc/example/email_partner.csv \
--stdout \
--tls-dir etc/example/dummy_certs
This protocol does an inner join based on email addresses as keys and then generates additive share of a feature associated with that email address. The shares are generated in the designated output files as 64 bit numbers
To run Company
env RUST_LOG=info cargo run --bin cross-psi-server -- \
--host 0.0.0.0:10010 \
--input etc/example/input_company.csv \
--output etc/example/output_company.csv \
--no-tls
To run Partner
env RUST_LOG=info cargo run --bin cross-psi-client -- \
--company localhost:10010 \
--input etc/example/input_partner.csv \
--output etc/example/output_partner.csv \
--no-tls
This is an implementation of Google's Private Join and Compute protocol, that does a inner join based on email addresses and computes a sum of the corresponding feature for the Partner.
