As one of the earliest key industries to start informatization construction in China, after 30 years of development, the financial industry has deposited a huge amount of data assets in the core system, including massive structured data like customers, accounts, products and transactions, as well as voices, images, videos and other unstructured data. Compared with other industries, the amount of data of bank customers is larger and basically reaches TB level and even PB level. Meanwhile, with many business directions and systems, the data use is indeed frequent in the whole circulation process. This brings a test to the support competence of the data masking product itself, especially for the performance, robustness and scalability of the product platform itself. As one of the four state-owned banks, Agricultural Bank of China is a major comprehensive financial service provider in China and a global systemically important bank. It has committed to building a modern financial service group with multi-functional coordination. In order to strengthen the protection of sensitive data of the Bank’s internal production system and reduce the risk of data leakage, the Bank decides to establish a set of appropriate management system for data masking in accordance with the relevant requirements of the Cybersecurity Law of the People’s Republic of China, Cybersecurity Law, Data Security Law, Personal Information Protection Law, Cybersecurity Classified Protection 2.0 and other laws and regulations.
