System, device, and method of providing authenticity and rights verification mechanism for media content and for its derived versions

A computerized method comprising:

• at a Media Authenticity Server,
• receiving a content item from a Content Creation Device,
• performing digital and cryptographic authentication of said Content Creation Device,
• and generating for said content item a Unique Content-Item Identifier (UCII), that operably accompanies said content item, and that uniquely identifies said content item, and that further indicates which modification operations are permitted with regard to said content item;
• subsequently,
• receiving from a Modification-Requesting Device, a Modification Request Descriptor which identifies said content item via said UCII, and which indicates a particular requested modification to said content item;
• authorizing said particular requested modification to said content item, only if said particular requested modification is indicated as permitted in said UCII;
• wherein the modification request is generated by a Social Media Server, which requests to provide a downscaled or mobile-friendly version of said content item for consumption by a particular end-user device;
• wherein the modification request is indicated by a Uniform Resource Locator (URL) that said Social Media Server provides to said particular end-user device,
• and which enables said end-user device to automatically request and obtain directly from said Media Authenticity Server the downscaled or mobile-friendly version of said content item that is generated by the Media Authenticity Server if the requested modification is indicated as permitted in said UCII.

A non-transitory storage medium having stored thereon instructions that, when executed by a processor, cause the processor to perform a method comprising:

• at a Media Authenticity Server,
• receiving a content item from a Content Creation Device,
• performing digital and cryptographic authentication of said Content Creation Device,
• and generating for said content item a Unique Content-Item Identifier (UCII), that operably accompanies said content item, and that uniquely identifies said content item, and that further indicates which modification operations are permitted with regard to said content item;
• subsequently,
• receiving from a Modification-Requesting Device, a Modification Request Descriptor which identifies said content item via said UCII, and which indicates a particular requested modification to said content item;
• authorizing said particular requested modification to said content item, only if said particular requested modification is indicated as permitted in said UCII;
• wherein the modification request is generated by a Social Media Server, which requests to provide a downscaled or mobile-friendly version of said content item for consumption by a particular end-user device;
• wherein the modification request is indicated by a Uniform Resource Locator (URL) that said Social Media Server provides to said particular end-user device,
• and which enables said end-user device to automatically request and obtain directly from said Media Authenticity Server the downscaled or mobile-friendly version of said content item that is generated by the Media Authenticity Server if the requested modification is indicated as permitted in said UCII.
