          How secure is user data?

          BOS provides different access control mechanisms (such as signature verification and access control list) to ensure the security of data stored by the user and prevent data from unauthorized access. Signature verification is used to verify the user’s identity by identifying the visitor through URL signature. The access control list is used for administration and check of Bucket.
