由 lltx1822 “How to Send Important Documents Most Securely?”
— A Complete Guide to International Shipping, Encrypted Transfers, and Legal Archiving
I. Why Are Important Documents Prone to Loss or Leaks?
- Three Major Risks in International Shipping
- Transit Risks: DHL 2024 statistics show 0.3% of international document shipments are lost (including passports, contracts, academic certifications).
- Customs Inspection: Sensitive documents (e.g., invoices, legal papers) may be opened for review.
- Data Breaches: Shipping labels are scanned and resold on the black market (e.g., corporate contracts for $200, personal IDs for $50).
- Latest Fraud Tactics (2025)
- Fake Delivery Notices: Scammers pose as couriers to send false “delivered” alerts while intercepting documents.
- Label Tampering: Altered addresses (e.g., “Chaoyang District, Beijing” → “Chaoyin District, Beijing”).
