AI DeepSign:Quick start

Purchase and activate AI DeepSign

1. Visit the AI DeepSign purchase page.

2. Select an edition and a duration based on your business requirements.

   • Edition:

     • Basic: suitable for low-frequency usage scenarios, such as testing or small-scale business.

     • Professional: suitable for high-frequency usage scenarios, such as production environments with large monthly call volumes.

   • Duration: You can purchase on a monthly basis, quarterly basis (3 months), or yearly basis (12 months).

3. Click Buy Now and complete the payment.

Role authorization (first time)

1. When you access the console for the first time, the system prompts you to authorize the required permissions. Follow the on-screen instructions to create the required role.

2. After the role is created, the system automatically creates the service-linked role AliyunServiceRoleForAIDeepSign. AI DeepSign uses this role to manage resources.

Generate an AI image and add a signature automatically

Use conversational AI to generate an image. The system automatically adds a C2PA digital signature to the generated image to ensure that each AI-generated work has a verifiable unique identity.

1. Log on to the AI DeepSign console.

   Note

   After you go to the page, the system starts a new task window by default. Two quick feature cards are displayed at the bottom of the page.

2. Click the Generate AI Image and Automatically Sign card at the bottom, or enter an image generation request in the dialog box. For example, enter "Generate a sunset seascape".

3. Press the send key (or press Enter). The system automatically generates the image and adds a C2PA digital signature.

4. After the image is generated, preview it in the dialog box. In the C2PA Signing Complete area below the preview image, view the signature information, including:

   • Signature Algorithm:The name of the algorithm used for signing.

   • Issuer:The issuing authority of the signing certificate.

   • Timestamp:The time when the signature was generated.

5. Click Download Signed File to download and save the image with the C2PA digital signature to your local device.

6. (Optional) Click C2PA Official Validation to go to the C2PA official verification site to verify the signature validity.

Detect and sign existing AIGC content

Upload existing AI-generated content (AIGC). The system automatically detects whether the content is AI-generated and adds a C2PA digital signature to it.

1. Log on to the AI DeepSign console.

2. In the dialog box, click the upload button and select the image file to detect.

3. After the image is uploaded, enter a detection request in the message input box (for example, "Detect the image"), and press the send key (or press Enter).

4. The system automatically completes the detection and analysis and displays the following results:

   • File Parsing Results: Basic information such as the file size, format, and resolution.

   • Sensitive information detection: Detects whether the image contains sensitive data and displays the results by risk level (S1: low risk, S2: medium risk, S3: high risk).

   • Signature certificate tracing: Detects whether the image already has a C2PA digital signature.

   • AI generation detection: Determines whether the image is AI-generated and provides a confidence score (≥90%: high risk, 60%–89%: medium risk, <60%: low risk).

5. (Optional) Add a C2PA digital signature to an unsigned image:

   1. In the Digitally Sign the Content with C2PA? area, click Personal Certificate Signature. The system generates a C2PA digital signature for the image.

   2. After the signature is complete, view the signature details in the C2PA Signing Complete area, and click Download Signed File to download the signed image.
