ApsaraVideo Media Processing (MPS) provides features such as data encryption, data isolation, and data leak prevention to protect data from potential security risks in the cloud.
Data encryption
Data transfer encryption
HLS encryption
HTTP-Live-Streaming (HLS) encryption uses Advanced Encryption Standard 128-bit (AES-128) to encrypt video content and supports all HLS-compatible players. HLS encryption must be used together with Key Management Service (KMS) and Security Token Service (STS). This encryption method is widely used in fields that require high security, such as online education and TV shows. For more information, see HLS encryption.
Server-side encryption
Alibaba Cloud proprietary cryptography
Alibaba Cloud proprietary cryptography encrypts video data. Video files downloaded to a local device are encrypted, which prevents unauthorized redistribution. This effectively prevents video leakage and hotlinking. Compared with HLS encryption, Alibaba Cloud proprietary cryptography is more secure and easier to use. For more information, see Alibaba Cloud proprietary cryptography.
Data isolation
Region isolation
Media resources and relevant configurations of an Alibaba Cloud account in MPS are region-bound. You cannot process media resources across regions. For example, if you activate MPS within an Alibaba Cloud account in the China (Shanghai) region, you cannot process media files stored in the China (Beijing) region.
Region isolation facilitates data storage and helps enterprises comply with local regulatory requirements and adapt to local culture. Region isolation also allows users to retrieve data from the nearest data center or server. This reduces the wait time and data latency and improves user experience.
Data leak prevention
Image or text watermarks
You can add image or text watermarks to videos to declare video copyright, promote brands, or improve brand recognition. This also prevents data leakage. For more information, see Add visible watermarks to videos.
Digital watermarks
You can add copyright or user-tracing watermarks to videos for copyright protection and video leakage tracing. Digital watermarks are invisible. You can use digital watermarks to prevent and trace data leakage. For more information, see Digital watermarks.
