Introduction
In-depth interpretation of the National Standard of the People's Republic of China GB/T 35632—2017
Analysis of the background of standard formulation and technological evolution
With the widespread application of surveying and mapping geographic information data, it is particularly important to protect data copyright and trace the source of data. As a core tool, digital watermark technology can effectively protect data copyright by embedding digital copyright identification. The formulation of GB/T 35632—2017 fills the gap in digital copyright identification technology in the field of surveying and mapping geographic information in China, and provides an important basis for data security and management.

Implementation suggestions
1. Technology selection and system integration:When selecting digital copyright identification technology, the visible or invisible embedding method should be determined according to specific needs. For data with high security requirements, it is recommended to use invisible digital copyright identification technology and combine encryption algorithms to ensure data security.
2. Data preprocessing and standardization: According to the standard requirements, the surveying and mapping geographic information data shall be standardized, including format conversion, cropping, compression and other operations. At the same time, it is recommended to adopt the industry-wide metadata specifications (such as GB/T 19710-2005) to ensure data compatibility.
3. Embedding and detection process optimization: When embedding digital copyright logos, it is necessary to control the embedding amount and visible level to avoid affecting the accuracy of the original data. It is recommended to use blind detection technology to improve detection efficiency and accuracy.
4. Quality management and evaluation: Establish a sound data quality management mechanism, conduct regular quality inspections, and assess the quality level of digital copyright logos according to standard requirements. For unqualified data, the logo should be repaired and re-embedded in a timely manner.
