Abstract: A system and method for managing files. The method includes sending by a user, to a server, a request for a file, receiving, in response to the request, an encrypted file and an encrypted file key associated with the file and the user, decrypting the encrypted file key using a private key associated with the user to obtain a symmetric key, and decrypting the encrypted file using the symmetric key to obtain the file. The files being managed are server resident files for any number of users, where the server is unable to encode or decode file data associated with the server resident files.

Abstract: A method and system for updating an interactive display on an interactive device. More specifically, the method is directed to the removal of identified stroke inputs from the interactive display. Each of the identified stroke inputs correspond to stroke data that at least partially overlap an enclosed area specified by a user via manipulation of a digitizer in erase mode.
