De-identified JSON Data Sample

The following is a structured JSON model of de-identified processing. The PII has been removed from the real name, ID number, mobile phone number, address, etc. and the core medical data is maintained. The exclusive map ID (anon_id) supports the vertical data series across the year.

Frequently asked questions

What are the data sources? How is quality assured?
In the public sector, medical examination centers are limited to cooperating medical institutions; in the private sector, high-end product lines are limited to brand-affiliated medical institutions. Each report is scored on a five-dimensional rating system: "medical breadth (20%) + data engineering clarity (15%) + medical standardization (15%) + clinical reasoning chain and image control (35%) + medical accuracy (15%)".
How does data de-identification work? Does the core medical information remain?
The following personal information is removed: real names, mobile phone numbers, identity card numbers, home addresses, email addresses, employers, photographs/headshots, and video attachments.
Is longitudinal data supported (i.e., continuous examinations of the same person over multiple years)?
Yes. Reports for the same natural person over three to five years of continuous examinations are linked via anon_id, a unique mapping. Year-over-year change analysis is recorded in a JSON field, with a dedicated temporal_comparison field, supporting disease progression modeling and time-series risk assessment.
Does it include original images? What is the data format?
Each report provides the original PDF plus structured JSON. All imaging examinations (ultrasound/CT/MRI/endoscopy/mammography/PET-CT) are accompanied by original image captures — a mandatory access threshold; reports containing only textual conclusions are not accepted.
How do you obtain data or business advice?
This dataset is provided byChangsha Langhui Information Technology Co., Ltd.The DataAssetsAPI platform is operated. It supports both customized datasets (flexible dimensions, quality tiers, and quantities) and standard datasets.
