IAM Side

To ensure that your personal data, such as the username, password, and mobile phone number, will not be obtained by unauthorized or unauthenticated entities or individuals, IAM encrypts your data during storage and transmission to prevent data leakage.

Personal Data

Table 1 lists the personal data generated or collected by IAM.

Usernames are used to identify users.

Password

Displayed in the Security Settings > Access Keys area of a specific user on the IAM console or on the My Credentials > Access Keys page.

Identity authentication during API calling

No

AK/SK cannot be modified, but they can be deleted and created again.

No

AK/SK are used to sign the requests sent to call APIs.

Data Storage Security

IAM uses encryption algorithms to encrypt user data before storing it.

  • Usernames and AKs: non-sensitive data, which is stored in plaintext.
  • Password: The password is encrypted using the salted SHA512 algorithm.
  • Email address, mobile number, and SK: Use the AES algorithm to encrypt and store them.

Data Transmission Security

Sensitive data (including passwords) of users is encrypted using TLS 1.2 during transmission. All IAM APIs support HTTPS to encrypt data during transmission.
