数据脱敏是指对某些敏感信息例如姓名、身份证号码、手机号、固定电话、银行卡号、邮箱等个人信息通过脱敏算法进行数据变形以保护敏感隐私数据。 数据脱敏通常涉及以下几种主要方法
替换 将原始数据中的敏感信息替换为不敏感的等效数据。例如将真实姓名替换为随机生成的名称将电话号码替换为虚构的号码。扰动 对数据进行微小的变化以使其仍然保持某种程度的统计一致性但不足以使个人身份可被轻松识别。这包括添加噪声或对数值进行微小的随机化。屏蔽 将敏感信息从数据中删除或隐藏。例如用特定字符或占位符替换敏感文本。一般化 减少数据的精确度使得数据更加模糊。例如将年龄精确到天数的数据一般化为年龄范围。删除 完全删除不必要的敏感信息。
