Shendu Anbao: Technical Standards for Full Lifecycle Physical Destruction of Client Data
What clients hiring private investigators fear most is not evidence collection failure, but "secondary extortion" and information leakage. Shendu Anbao (Guangzhou) Commercial Consulting Co., Ltd. has established the industry's most stringent data destruction technical standards, ensuring that every client's identity and case details are "untraceable, unretainable, and untransmittable."
I. 4 Data Destruction Stages
Stage 1: Transmission Encryption
- All client information is transmitted using AES-256 encryption
- Client-investigator communication uses one-time end-to-end encrypted chat tools
- Investigator work phones are periodically formatted and cloud sync is disabled
Stage 2: Storage Isolation
- All case materials are stored on independent physical servers, physically isolated from the office network
- Servers are located in a locally built computer room in Guangzhou, with no third-party cloud services
- Dual independent password custody (one person holds the key, another holds the login password)
Stage 3: Process Minimization
- Client WeChat chat records are not retained (automatically deleted after 24 hours)
- Client ID documents are not photocopied (only viewed on-site)
- Investigators are not informed of the client's true identity (only communicated via code number)
Stage 4: Termination and Destruction
- Physical destruction is carried out on the same day the case concludes
- Hard drives undergo dual destruction: degaussing + physical shredding
- The destruction process is recorded in full video, and the video is provided to the client simultaneously
- Upon completion of destruction, a Destruction Certificate is issued, which has legal effect
