Abstract
The disclosure relates to, among other things, systems and methods for augmenting and/or otherwise supplementing content using watermarks. Consistent with embodiments disclosed herein, a user device such as a smartphone may be used to retrieve watermark information encoded in a watermark. The watermark information may comprise content that supplements an associated content item, link and/or location information that may be used to retrieve supplemental content, and/or the like. In some embodiments, the watermark information may comprise cryptographic and/or other access token information used to decrypt and/or otherwise access supplemental content.
Claims18
A method for managing access to supplemental electronic content associated with a content item performed by a user device comprising at least one processor and at least one computer-readable storage medium storing instructions that, when executed by the at least one processor, cause the user device to perform the method, the method comprising:
- detecting a watermark associated with the content item, the watermark encoding watermark information;
- accessing content information included in the watermark information;
- analyzing the content item to determine content characteristics associated with at least a portion of the content item;
- generating a binding value based, at least in part, on at least a portion of the content information and the determined content characteristics associated with the at least a portion of the content item;
- querying a ledger service system to determine whether the binding value has been recorded in a trusted ledger managed by the ledger service system;
- receiving a response from the ledger service system indicating that the binding value is recorded in the trusted ledger;
- and
- accessing, based on receiving the response, the supplemental electronic content using the watermark information.
