Wrapped Encryption Layers for Selective Data Revelation

The patent segments the dataset into individual data items and applies separate encryption layers to each item. Instead of encrypting the entire dataset as a single unit, each data item is independently encrypted with its own encryption key, allowing selective decryption and revelation of specific items based on authorization levels.

The patent implements a nested encryption structure where multiple encryption layers are applied to data items in sequence. Each data item is wrapped in successive encryption layers, with inner layers having higher security requirements. This nested structure enables progressive revelation of data items based on the number of decryption keys possessed by the accessing party.

The patent assigns different security properties to different data items based on their sensitivity and importance. Each data item can have a customized number of encryption layers and associated access controls, rather than applying a uniform encryption scheme to the entire dataset. This local quality approach enables fine-grained access control while maintaining simplicity for less sensitive data.

The patent adds a dimensional aspect to encryption by introducing multiple layers of encryption with different security levels. Instead of a single encryption dimension, the system creates a hierarchical structure where data items can be accessed at different depths based on authorization, transforming the encryption model from flat to multi-dimensional.
