Patent ID: 8200281

Claim:
A removable card having electrical connections for connecting to a mobile wireless communicating device for use by a user to access a common carrier network to access a network of interconnected computer networks (“Internet”), comprising: a processor; a non-volatile memory connected to the processor, having two portions: a first portion and a second portion wherein said first portion is accessible by the provider of the common carrier network with said processor restricting access thereto by the user, and wherein said second portion is accessible by the provider of the common carrier network and with said processor granting access thereto to the user for storing user data therein; and logic circuit for encoding the user data to produce encrypted user data, wherein said encrypted data is stored in said second portion; wherein said logic circuit comprising a volatile memory for storing a user supplied password, wherein said password is stored in said volatile memory only when power is supplied to said memory; an encryption circuit for receiving the user supplied user data and the output of the volatile memory and for encrypting said user data with said password from said volatile memory to produce encrypted user data, and for storing said encrypted user data in said second portion; and a decryption circuit for receiving encrypted user data stored in the second portion and the output of the volatile memory and for decrypting said encrypted user data with said password from said volatile memory to produce user data.
