What does the boolean response 'true' from the watermark verification endpoint signify?
Conditions
- The request has already been executed.
- The server returns status '200'.
Reasoning, step by step
- Execute the GET verification request with the correct queryId, key, and alpha.
- Inspect the Server response section.
- Read the Response body panel to see the boolean value.
Example
When the verification endpoint returns 'true', the speaker interprets this as confirming that the dataset belongs to the requester. The response area shows HTTP status 200 and a response body of true.
Common misconceptions
- Thinking the API result is a full mathematical derivation. The video demonstrates request parameters, generated URL, and boolean response only; it does not present the verification algorithm, proof, or error model.

The same private key must be used because the watermark was generated using that specific key. The system does not record private keys for privacy reasons, so the user must supply the identical key again during verification to prove ownership.
Conditions: A watermark was generated using a private key.; The verification endpoint is called with that watermark-related hash.
The Data Provenance tool is designed to watermark personal data, such as browsing datasets, so that data ownership can be verified later. It allows users to retain proof of possession or attribution when sharing or monetizing their data.
Conditions: Applies to personal data such as browsing datasets.; The tool verifies ownership rather than completing the whole trading process.
The original IPFS hash is used as the 'queryId' path parameter in a POST request to the endpoint '/ipfs/dataset/{queryId}'. Executing this request sends the hash to the watermarking module, which returns a JSON response containing a 'newHash' identifier.
Conditions: Use the previously obtained IPFS hash as 'queryId'.; The request method is POST.; The response includes 'newHash' and other metadata fields.
The video indicates that the file can be downloaded from the 'Download' button located in the response controls area of the Swagger UI, below the response body section.
Conditions: The interface is a Swagger UI page.; The response has been executed and is visible.
The alpha threshold should be set to 7 when the dataset or file contains exactly seven URLs and the goal is to verify that all seven URLs are correct and belong to the user. Setting it to 7 requires all seven checks to pass.
Conditions: The dataset/file is described as having seven URLs.; The intended verification is that all seven are correct and belong to the user.; 'alpha' is an integer query parameter.
