Watermark Detection API Guide

Watermark detection analyzes each frame of the video to detect the original watermark pattern and decrypts the data with the secret key used at the time of insertion. If the watermark payload is found through the detection process, the session database finds the session information whose key value is the payload and reports it as the detection result.

sequenceDiagram
    participant A as Service site
    participant B as DoveRunner service
    A ->> B: Suspicious content
    Note right of B: Detect watermark (payload)
    B -->> B: Analyze video frames
    opt Watermark detected
    Note right of B: Session database
    B -->> B: Find session data
    end
    B ->> A: Report detection result

Requirements for Detection

Note

For watermark detection, a continuous recorded video of at least 5 minutes or longer is required. DoveRunner Forensic Watermark solution is robust against various attacks including resizing, but the actual detection rate of the watermark may vary depending on the video quality (resolution, bitrate, shake, etc.) used for detection. The minimum specification required for detection is 480p 1Mbps or higher, and most of the video over 720p can be detected.

The detailed requirements for watermark detection are as follows:

Item	Description
Minimum video length	In order to detect watermarks, continuous recorded video without repeating sections with a length of at least 5 minutes is required
Video quality	At least 480p with 1Mbps is required for detection. 720p or higher quality recommended
Video stability	Requires fixed recorded video without shaking. Undetectable if the screen is shaken due to shooting with a handheld camera or smartphone
Buffering or freezing	There must be a section that was played normally without buffering or screen freezing for at least 5 minutes

DoveRunner HTTP API Specification

The HTTP API requests used by the DoveRunner service follow the specifications below.

Please find the API request sample code in Sample Download page.

Request

Name	Value
pallycon-apidata	base64 Encoding ( JSON string )

Request Data JSON Format

{
    "data":"{aes256 cbc encryption of 'API data' for each API, and base64 encoding}",
    "timestamp":"{yyyy-mm-ddThh:mm:ssZ}",
    "hash":"{sha256 hash of 'message format' in base64 string}"
}

Request Data Specification

Name	Value	Required	Description
data	String	Y	AES encryption on the JSON string generated by the specification for each API, and the result value is input as a base64 string.
timestamp	String	Y	Enter the time of the request at the GMT time zone in “yyyy-mm-ddThh: mm: ssZ” format.
hash	String	Y	Enter the hash value generated according to the following specification.

AES256 Encryption

Aes256 encryption / decryption processing is performed as below using the site key value issued when joining DoveRunner service. (Check DoveRunner Console site)

• mode : CBC
• AES key : 32 byte (Site key issued from DoveRunner Console site)
• AES IV : fixed 16 byte (0123456789abcdef)
• padding : pkcs7

SHA256 message Format

The input value of the SHA256 hash is a combination of the following strings.

[site access key] + [site_id] + [json.data] + [json.timestamp]

• site access key: It is the access key value that is issued when creating DoveRunner cloud service site. It can be checked on the DoveRunner Console page.
• The resulting value of the sha256 hash function must be input to the base64 function as a binary data, not as a string.

JWT Authorization Specification

You can call the Session API by setting the data issued through the token api in the Authorization header.

Authentication Token

When calling the Session API, you need to set an authentication token issued by the process below.

Step 1: Generate the base64 encoded Authorization parameter

1. Navigate to Base64 Enc/Dec page on DoveRunner DevConsole.
2. While Encrypt option is selected, enter the AccountID:AccessKey value in the left text field.
3. Base64 encoded output will be displayed as the screenshot below.
4. Copy the output value to use in the next step.

You need to input the AccountID and AccessKey values for your DoveRunner service account.

Step 2: Use the parameter value to generate the Authorization token.

Call the token API URL with base64 encoded value in the Authorization request header.

• URL: https://api.pallycon.com/api/token/[SITE_ID]/
• Method: GET
