在 SQL 中,可以使用 SELECT
語(yǔ)句中的 REPLACE
函數(shù)或者 SUBSTRING
函數(shù)來(lái)對(duì)敏感數(shù)據(jù)進(jìn)行脫敏處理。下面是一些示例:
REPLACE
函數(shù)對(duì)手機(jī)號(hào)進(jìn)行脫敏:SELECT REPLACE(phone_number, SUBSTRING(phone_number, 4, 4), '****') AS masked_phone_number
FROM customers;
SUBSTRING
函數(shù)對(duì)郵箱地址進(jìn)行脫敏:SELECT CONCAT(
SUBSTRING(email, 1, 3),
REPEAT('*', CHAR_LENGTH(email) - 7),
SUBSTRING(email, CHAR_LENGTH(email) - 3)
) AS masked_email
FROM customers;
REPLACE
函數(shù)對(duì)身份證號(hào)進(jìn)行脫敏:SELECT CONCAT(
SUBSTRING(id_number, 1, 6),
REPEAT('*', CHAR_LENGTH(id_number) - 10),
SUBSTRING(id_number, CHAR_LENGTH(id_number) - 3)
) AS masked_id_number
FROM customers;
通過(guò)以上方法,可以對(duì)敏感數(shù)據(jù)進(jìn)行脫敏處理,保護(hù)用戶的隱私信息。
