Recommendations for Opt-out

Liccium's TDM·AI protocol describes the method of binding rights reservations to ISCC codes, such as an opt-out declaration. To be effective, rights reservations must be:

• Inseparably bound to the fingerprint of the content allowing sharing and distribution of content;

• Easily discoverable, accessible and machine-readable (legal requirement in the EU);

• Functional when content already has been shared and distributed;

• Declarations can be updated;

• Resilient to content manipulation or alteration;

• Resilient to the removal of embedded metadata and visible or invisible watermarks;

• Containing verifiable attribution through digital signatures and certificates which authenticate the declaration's source and prevent false claims;

• Functional for all media types and file formats;

• Utilising verifiable timestamps;

• Based on reliable and transparent international standards (ISO, W3C).
