Abstract: A method for interacting with a user, comprising communicating with at least one cooperative server through a normal browser; automatically receiving encrypted data having an associated received type code indicative of a requirement for a secure browser having restricted functionality with respect to a functionality of the normal browser; selectively and automatically invoking the secure browser for handling of the received encrypted data based on the received type code associated with the received encrypted data; receiving the encrypted data with the invoked secure browser for handling thereof, wherein the received encrypted data is not available for use by the user in the normal browser and the invoked secure browser imposes restrictions on availability outside of the secure browser of decrypted data derived from the encrypted data; and communicating an input from the user, through the secure browser, to the at least one cooperative server.

Abstract: A secure user interface method, for interacting with a user through a browser, comprising the steps of controlling the browser to request a document from a cooperative server, the browser providing data export support functionality; receiving data with the browser in response to the request; determining, based on a type encoding of the received data, whether a secure browser is to be employed, the secure browser having a set of functionality restricted with respect to a normal browser, to enhance security of a received document against data export; authenticating the secure browser, to assure that the secure browser having the restricted set of functionality is available for presentation of secure content; receiving the secure content for presentation in the secure browser; and communicating an input from the user, through the secure browser, to a cooperative server.
