# Recommendations for Opt-out

Liccium's TDM·AI protocol describes the method of binding AI preferences to ISCC codes. 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 international standards (ISO, W3C).
