Overview

OBS is widely used as the storage for mobile Android and iOS apps. When accessing OBS from Android or iOS apps, do not directly save access keys (AK/SK). If the access keys are saved, they may be cracked by hackers, and as a result, data stored in the cloud storage may be stolen or even tampered with.

To better protect data and prevent data leakage and unauthorized access after attacks, you can use the following two methods:

• Using a Temporary Security Credential to Upload Data to OBS
• Using a Presigned URL to Upload Data to OBS

In method 1, a temporary AK/SK pair is used to avoid leakage. You are advised to use a temporary security credential to directly upload data to OBS.
