Sensitive citizen data, such as complete national identification card numbers and phone numbers, must be encrypted or masked at rest inside the primary database columns. This ensures that even raw backups do not contain plaintext personal information. 5. Regular Security Vulnerability Scanning

: Under the Personal Information Protection Law (PIPL) and similar global regulations, the distribution of ID data is a severe offense. 3. How to Respond (If you found this file) shifenzheng.bak
Developers working with SQL databases, local SQLite instances, or Android/iOS app development often create backup tables. If a database contains a column or table for user identification, exporting it can result in a shifenzheng.bak file.
The backup typically contains detailed personal information of millions of individuals, including: Full Names ID Numbers (Shenfenzheng) Mobile Phone Numbers Email Addresses Home/Registration Addresses Hotel Check-in/Check-out Times How to access the content (Technical steps) To view the contents of a If a database contains a column or table
Occasionally, users who speak Chinese may manually name a backup file of their scanned ID card shifenzheng.bak before modifying the original image file (e.g., cropping it, compressing it, or adding a watermark) to change its format from .jpg or .png to .bak as a rudimentary way to hide the file from photo galleries. What is Inside a shifenzheng.bak File?
: A server might be configured to keep .jpg files private but might serve .bak files as plain text or downloadable binaries. isolating peripheral networks from core databases.
Modern ID card and document management has largely moved to mobile apps that function very differently from the old database backup files. These apps are designed for convenience and security:
Zero-trust architecture; isolating peripheral networks from core databases. National IDs and phone numbers stored without hashing.
