Synthetic Twins

Private clinical data, safely copied

Three ways to get data

Buy it. Train on it. Or twin it.

Sellers choose which access methods they offer. You choose how close you need to get to the raw records.

01 · Download License

Buy & download

Download the full verified dataset with a clear license detailing AI training and commercial rights. Keep it permanently in your S3/GCS buckets.

job.py

weights.bin

02 · Compute-to-data

Train in place

Send your containerized training job into the seller's secure enclave. It trains directly beside the records, and returns model weights — never the raw customer rows.

03 · Privacy Preserving

Get a synthetic twin

For clinical or private financial data, download a mathematically validated synthetic copy with identical statistical distributions, zero PII, and full privacy guarantees.

Trust & Licensing

Every stall is inspected before it opens.

ByteBazaar validation agents inspect every dataset before listing and continuously audit on each version update.

Schema & Completeness Columns match published docs. Missing values are precisely measured, never hidden.
Privacy & PII Scanning Comprehensive regex, NER, and biometric checks eliminate direct personal identifiers.
Provenance Verification Sellers submit legal documentation proving original ownership and sublicensing rights.
