Tencent Cloud's video surveillance storage solution employs multiple layers of encryption to ensure data security both in transit and at rest.
-
Data Encryption at Rest:
- Stored video footage is encrypted using industry-standard AES-256 (Advanced Encryption Standard with 256-bit keys). This ensures that even if physical storage media is compromised, the data remains inaccessible without the encryption keys.
- Example: A surveillance system recording footage in a retail store stores all video files in an encrypted format on Tencent Cloud's object storage (COS), preventing unauthorized access.
-
Data Encryption in Transit:
- Video streams transmitted from cameras to the cloud are encrypted using TLS (Transport Layer Security) or SSL (Secure Sockets Layer) protocols. This protects data from interception during transmission.
- Example: A smart city project uses Tencent Cloud's video surveillance solution where live feeds from cameras are securely transmitted to the cloud over HTTPS.
-
Key Management:
- Encryption keys are managed through Tencent Cloud's Key Management Service (KMS), which provides secure key generation, storage, and rotation. Customers can choose to manage keys themselves or let Tencent Cloud handle it.
- Example: A financial institution uses KMS to control access to encryption keys for its surveillance data, ensuring compliance with regulatory requirements.
-
Access Control and Auditing:
- Access to encrypted data is restricted through role-based permissions, and all access attempts are logged for auditing.
- Example: A corporate office restricts access to surveillance footage to authorized personnel only, with all access events recorded in audit logs.
For video surveillance needs, Tencent Cloud offers Cloud Video Surveillance (CVS) and Cloud Object Storage (COS), which integrate these encryption features to provide a secure solution.
