Abstract
A Document Card (DocuCard) for storing documents and which is content revealing. The DocuCard is a transportable unit having a nonvolatile storage means for storing information in a digital form, a control processor for processing user initiated functions; an I/O port for interfacing to external devices for reading and writing digital information, and a user interface for allowing a user to directly interact with the DocuCard. The user interface on the DocuCard includes a display for displaying lists of functions and documents and information responsive to user invoked functions and a user input portion for allowing a user to traverse the lists of functions and documents, as well as information generated responsive to an invoked function. The control processor of the present invention include features for controlling access to documents stored therein.

17. A method for accessing documents stored in a repository from a DocuCard, said documents stored in said repository having one or more usage rights attached thereto, said usage rights indicating a particular manner by which said document may be used, said DocuCard comprised of a display, a plurality of traversal keys and a select key, said method comprising the steps of:
-
a) a user coupling said DocuCard to said repository; b) displaying on said display of said DocuCard a list of functions for accessing a document stored on said repository, each of said functions representing an instance of how a selected document is used, each of said functions corresponding to an instance of a usage right; c) said user selecting a function from said displayed list of functions; d) displaying on said display of said DocuCard a list of the contents of said repository; e) said user selecting a desired document from said list of contents of said repository; f) said repository determining if said desired document has said instance of a usage right corresponding to said selected function; g) if said desired document has attached thereto said usage right corresponding to said selected function, said repository granting access to said document; and h) if said desired document does not have attached thereto said usage right corresponding to said selected function, said repository denying access to said document. - View Dependent Claims (18, 19, 20, 21, 22, 23)
