Sensitive data protection fees-Object Storage Service(OSS)-阿里云帮助中心

When sensitive data discovery and protection (SDDP) is enabled for a bucket for the first time, OSS scans all data in the bucket. You are charged for all scanned data. After the first scan is complete, SDDP scans only added or modified data in the bucket. You are charged only for scanned data.

Note

For unit prices of each billable item, see .OSS product pricing

Billable items

Sensitive Data Protection provides a free quota of 200 GB per month for the scanned data volume (SddpScanSize). You are not charged if the total data volume scanned in a month is 200 GB or less. The free quota applies only to the scanned data volume of Sensitive Data Protection and does not cover the credits consumed by AI text detection or AI image detection. For more information about free trials, see Alibaba Cloud Free Trial.

Important

The free quota of 200 GB per month is calculated per Alibaba Cloud account and can be used across all regions and storage classes.

Billable item	Billing rule	Billing cycle	Billing method
Scanned data volume for Sensitive Data Protection (SddpScanSize)	Fees are incurred for full or incremental scans of authorized data sources.	Billed hourly. Bills are generated after the current billing cycle ends. The actual time when a bill is generated is determined by the system.	Pay-as-you-go: Scan fee = Scanned data volume (GB) × Unit price per GB Resource plan: Not supported
AI text detection	Detection that the large model detection capability performs on text. Each text is detected as one detection if it contains no more than 2,000 characters; longer text is counted as multiple detections.	Billed hourly. Bills are generated after the current billing cycle ends. The actual time when a bill is generated is determined by the system.	Pay-as-you-go: Detection fee = Number of detections × 0.15 credits Resource plan: Not supported
AI image detection	Detection that the large model detection capability performs on images. Each image is detected as one detection only if it is no larger than 10 MB. Larger images are not detected.	Billed hourly. Bills are generated after the current billing cycle ends. The actual time when a bill is generated is determined by the system.	Pay-as-you-go: Detection fee = Number of detections × 0.3 credits Resource plan: Not supported

AI text detection and AI image detection are billed in credits at CNY 1 per 100 credits. Starting from 00:00:00 on November 13, 2026 (UTC+8), the large model detection capability will be gradually billed on a pay-as-you-go basis in credits.These detections are billed on a pay-as-you-go basis in credits at CNY 1 per 100 credits, and the exact number of credits consumed is subject to your bills.

If you do not need the large model detection capability, go to the Data Service Content Security page in the OSS console, open the Identification Configuration tab, and turn off the Large Model Invocation switch for each item. After you turn off the switches, no credits are consumed, but the sensitive data detection accuracy may decrease.
