Abstract

Systems and methods are disclosed for allowing an authority to monitor a computer user's information in a most palatable manner for the computer user. The authority is provided access to information with encrypted user identification information and the user is notified if decryption is facilitated. The systems and methods also include a novel key production system whereby large numbers of deterministic key pairs may be created for use in the monitoring system.

First claim

What is claimed is:

1. A method comprising the acts of:
storing a master key value associated with a user;
generating a public and private key pair including a public key and a private key for content of the user, including:
obtaining a descriptor value from the content, and modifying a portion of the master key value using the descriptor value by:
deriving a series of bits from the descriptor value, determining a size of the series of bits derived from the descriptor value,…
