Abstract
A method and system for creating secure Internet user states between one or more servers and one or more users. The invention is carried out by a server receiving over the Internet from a user private data relating to the user and a user key; creating an encryption key from the user key; encrypting the private data with the encryption key; assigning the encrypted private data to the data field of a cookie; and sending the cookie back to the user's computer for storage, so that when the user later requests data from the server or a related server, the cookie is sent back by the user's computer to the server or related server, which extracts the encrypted private data; receives the user key; recreates the encryption key; decrypts the encrypted private data with the encryption key and uses the decrypted private data to establish an Internet state between that server and the user. Optionally, the private data may be seeded by a server prior to encryption and assignment.
