## Abstract

A display device establishes a secure communications session with a mobile device and receives an image-based item associated with a unique cryptographic token. The display device determines, based on metadata parsed from the unique cryptographic token, authenticity information and chain-of-ownership information for the cryptographic token. In response to determining that user account information for the secure communications session corresponds to an item included in the chain-of-ownership information, the display device displays the image-based item, and an indicator component of the display device provides an indication of authenticity for the image-based item.

## Claims

### Claim 1

One or more computer-readable media excluding transitory signals and having computer-executable instructions stored thereon, the instructions configured to cause at least one processor of a mobile phone or tablet device to perform operations comprising:
establishing, by the at least one processor, a first secure wireless communications session between the mobile phone or tablet device and a first visual display device and a second secure wireless communications session between the mobile phone or tablet device and a second visual display device;
generating and displaying, on a display of the mobile phone or tablet device, a first graphical user interface (GUI) structured to allow a user to:
perform a first cast operation, comprising casting a first image-based digital artwork associated with a first non-fungible token (NFT), via the first secure wireless communications session, to the first visual display device; or
perform a second cast operation, comprising casting a second image-based digital artwork associated with a second non-fungible token (NFT), via the second secure wireless communications session, to the second visual display device;
in response to detecting a first user input via the first GUI, performing at least one of the first casting operation or the second casting operation; and
generating and displaying, on the display of the mobile phone or tablet device, a second graphical user interface (GUI) structured to allow the user to adjust properties associated with the first casting operation or the second casting operation, the properties relating to two or more of:
music to be played concurrently with displaying the first image-based digital artwork or the second image-based digital artwork;
duration of time for displaying the first image-based digital artwork or the second image-based digital artwork;
aspect ratio of the first image-based digital artwork or the second image-based digital artwork;
mat color for the first image-based digital artwork or the second image-based digital artwork;
artwork information panel for the first image-based digital artwork or the second image-based digital artwork;
ownership status display setting for the first image-based digital artwork or the second image-based digital artwork.

### Claim 2 (depends on 1)

The media of claim 1, the operations further comprising:
parsing, by the at least one processor at the mobile phone or tablet device, metadata associated with at least one of the first NFT and the second NFT; and
determining, by the at least one processor, ownership status for the at least one of the first NFT and the second NFT, comprising comparing, by the at least one processor, a parsed metadata item to a logged-in user account item.

### Claim 3 (depends on 2)

The media of claim 2, the operations further comprising:
transmitting, via the first secure wireless communications session or the second secure wireless communications to a respective visual display device, visual indicator configuration information determined based on the ownership status and a second user input provided via the second GUI.
