Introduction
1. Background of standard formulation and analysis of technological evolution
The National Standard of the People's Republic of China GB/T 21679-2023 "Specifications for the Construction of Forensic Science DNA Databases" was released in 2023, replacing the old version of 2008. The standard mainly revised and improved the terminology, technical requirements, and security management of DNA databases. With the advancement of criminal science and technology and the increasing importance of network security, the new standard adds definitions of key terms such as mitochondrial DNA and short tandem repeats (STRs), and clarifies the technical framework for the construction of DNA databases.
2. Comparison of standard frameworks
| Dimensions | Old standard (GB/T 21679-2008) | New standard (GB/T 21679-2023) |
|---|---|---|
| Term definitions | Key terms such as "locus" and "STR" are not clearly defined | Definitions of terms such as "locus", "STR", "mitochondrial DNA" and "hypervariable region" are added and clarified |
| Technical requirements | Mainly focus on database functional modules and basic construction requirements | Added registration management of reagents and equipment, and clarified the STR test sequence and technical parameters |
| Security requirements | Network security and data protection are not covered in detail | New requirements for network security level protection and data backup mechanism are added |
3. Implementation suggestions
3.1 Training of technical managers
- Regularly organize technical managers to participate in network security and data management training
- Ensure that laboratory personnel are familiar with the terminology and operating procedures in the new standard
3.2 Reagent and equipment management
- Register testing reagents and equipment in strict accordance with the requirements of the standard
- Establish a sample library for quality control personnel to ensure data accuracy
3.3 Data security management
- Implement a network security level protection system
- Regularly back up the database and store it properly
- Prevent unauthorized access and data leakage
