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.
Claims20
A method for managing access to supplemental electronic content associated with a content item performed by a user device comprising a processor and a computer-readable storage medium storing instructions that, when executed by the processor, cause the user device to perform the method, the method comprising:
- capturing, using a sensor system of the user device, an image of a watermark associated with the content item;
- retrieving, from the image of the watermark, encrypted watermark information encoded in the image of the watermark;
- receiving, from a wireless communication component, a cryptographic decryption key;
- decrypting the encrypted watermark information encoded in the image using the cryptographic decryption key received from the wireless communication component to generate decrypted watermark information;
- and
- accessing the supplemental electronic content using, at least in part, the decrypted watermark information.
The method 17, wherein determining that the watermark is securely bound to the content item comprises:
- comparing the at least one characteristic of the watermark with the at least one characteristic of the content item;
- and
- determining that the at least one characteristic of the watermark and the at least one characteristic of the content item have at least one defined relationship.
