Data masking is also called data anonymization. Huawei Cloud data masking is implemented using methods such as masking, noise addition, enumeration, truncation, hashing, and marking to protect user identities and sensitive information from being associated with data, and to mask the characters in personal data, thereby protecting data privacy and reducing data leakage risks. Huawei Cloud has also developed cloud services with this feature, such as Data Security Center (DSC).
