System and method for blockchain-based consent and campaign management

Abstract

A specialized networking and application system which includes a consent and campaign blockchain network for advertising campaigns. Off-chain databases are used to store a user's personal data records that are not suitable to be stored in blockchain ledger system. A user receives an opt-in request link prompting the user to consent to receiving advertising campaign messages. The invention verifies user's consent using a single-use token and, if the verification is successful, the advertising campaign messages are transmitted to the user. The invention enables users to centrally manage their consents/preferences for various enterprises, various channels and/or campaigns, storing encrypted subscribers' consents/preferences data into trusted blockchain network, validating the preferences before delivering a campaign message to the user, and providing audit trials and historical campaign messages with analytic data to the users.

AI Technical Summary

Benefits of technology

[0006]In one embodiment, the present invention provides a method for consent and campaign management which includes, transmitting, by an enterprise, an opt-in request to a user, the opt-in request for inviting the user to consent to receive one or more messages related to a campaign, wherein the opt-in request comprises a link to a blockchain network. The method further includes, generating a single-use token in response to the user accessing the blockchain network via the link to the blockchain network, transmitting the single-use token to the user and, responsive to the user logging into the blockchain network using the single-use token, issuing a private key to the user. The method further includes, receiving a user's response to the opt-in request, wherein the user's response includes the user's personal data, encrypting the user's personal data using the private key and storing the user's personal data in an off-chain database, logging the user's response to the opt-in request into the blockchain network, validating the user's opt-in response as consent to receive messages pertaining to the campaign and transmitting the campaign message to the user based upon the validation of the user's opt-in response and logging delivery of the campaign message into the blockchain network.

Problems solved by technology

However, currently there is no common place for users to manage their consent / opt-in preferences.

The absence of a central user consent management system leads to replication of the process that could be time consuming and tedious for the users whenever they need to modify or delete their personal information and consent with the consent management system of each individual enterprise.
