Method and apparatus for displaying advertisements
The holding apparatus having an embedded display device that is configured to display a plurality of advertisements in a secure manner for a pre-defined time interval. The holding apparatus comprises a bottom/middle section configured to hold one or more objects, and a plurality of holder sides disposed at each lower end of the bottom/middle section. The holding space is utilized for keeping objects, such as napkins, menu card. Further, a puck connected to a virtual mesh Wi-Fi network 114 connects to a private block chain and the display device to securely display advertisements on the display device of the holding apparatus.
1 . A holding apparatus for displaying advertisements, the holding apparatus comprising:
a bottom/middle section for holding one or more objects;
a plurality of holder sides disposed at each lower end of the bottom/middle section;
a top/middle section;
a battery housed within a battery compartment; and
a screen back plate to providing support to a display device embedded within each of the plurality of holder sides, wherein the display device securely displays one or more advertisements for a pre-defined time interval, using a private blockchain network, the private blockchain network providing a cryptographically secure and authoritative source for operational data and procedural applications that execute a real-time display of the one or more advertisements with deterministic playback verification,
wherein the deterministic playback verification comprises:
(a) performing, prior to displaying an advertisement, an integrity check of a smart contract associated with the advertisement retrieved from the private blockchain network; and
(b) executing, subsequent to displaying the advertisement, a blockchain transaction to immutably record the playback of the advertisement on the private blockchain network.
2 . The holding apparatus as claimed in claim 1 , wherein the battery compartment is a removable battery compartment.
3 . The holding apparatus as claimed in claim 1 , wherein the display device caches one or more advertisements and associated cryptographic verification data from the private blockchain network, enabling the secure and deterministic display of the one or more advertisements during a period of disconnection from an external network.
4 . The holding apparatus as claimed in claim 1 , wherein the operational data includes a unique AdUnit identifier for each advertisement playback event, the AdUnit identifier comprising a dot-hexadecimal notation that maps the playback event to a specific smart contract on the private blockchain network.
5 . A method for securely displaying advertisements on a display device embedded within a holding apparatus, the method comprising:
utilizing a private blockchain network as a cryptographically secure and authoritative source for operational data and procedural applications for executing a real-time display of one or more advertisements;
performing, prior to displaying a first advertisement of the one or more advertisements, an integrity check of a smart contract associated with the first advertisement, the smart contract being retrieved from the private blockchain network;
displaying the first advertisement on the display device subsequent to a successful integrity check; and
executing, subsequent to displaying the first advertisement, a blockchain transaction to immutably record the playback of the first advertisement on the private blockchain network.
6 . The method of claim 5 , further comprising:
caching, on the holding apparatus, a schedule of advertisements and associated smart contracts for a pre-defined time interval;
wherein the steps of performing the integrity check and displaying the first advertisement are executed autonomously by the display device during a period of disconnection from an external network.
7 . The method of claim 5 , wherein the step of performing the integrity check of the smart contract is preceded by a step of identifying the smart contract using a unique AdUnit identifier, the AdUnit identifier comprising a dot-hexadecimal notation that maps the playback event to a specific address of the smart contract on the private blockchain network.
