Linked Account Purchase Control Using Parent-Child Authorization

The patent segments the account system into a parent account and multiple child accounts. The parent account holder maintains control over payment methods and authorization, while child accounts can make purchases only with explicit or pre-approved permission. This segmentation allows ease of operation for child accounts (no need to manage payment details) while maintaining reliability through parent account authorization controls.

The parent account acts as an intermediary between the payment account information and the child accounts. The parent account holder stores sensitive payment information and grants selective access to child accounts. This intermediary layer prevents direct exposure of payment credentials to child accounts, ensuring transaction security while maintaining operational convenience.

The patent divides a single account into multiple distinct child accounts, each with unique identifiers and profiles. This segmentation enables precise identification of which specific user is making a purchase or accessing content, while still allowing multiple users to access the shared parent account benefits. Each child account maintains its own activity history and permissions.

The patent implements a nested account structure where child accounts are nested within the parent account. The parent account contains multiple child accounts, each with their own sub-accounts or profiles. This nested structure enables the system to track and identify transactions at the individual child account level while maintaining the hierarchical relationship and shared resources of the parent account.
