Abstract: A method and system for assisting a user of a data processing system (101) in browsing a file system (AAA-LLL,aaa-eee) by means of a browsing program (203). A browsing history database (209) is created by intercepting (205,403,417) browsing events from the browsing program, the database including browsing starting locations (STR—LOCa–STR—LOCq) and links to associated browsing target locations (TRGT—a1–TRGT—ak,TRGT—b1–TRGT—bp,TRGT—q1,TRGT—q2) reached by the in the browsing. When the user starts a browsing, the current browsing starting location is intercepted from the browsing program. The intercepted browsing starting location is searched in the database.

A browsing history database (209) is created by intercepting (205,403,417) browsing events from the browsing program, the database including browsing starting locations (STR_LOCa-STR_LOCq) and links to associated browsing target locations (TRGT_a1-TRGT_ak,TRGT_b1-TRGT_bp,TRGT_q1,TRGT_q2) reached by the in the browsing. When the user starts a browsing, the current browsing starting location is intercepted from the browsing program. The intercepted browsing starting location is searched in the database.

Abstract: A method (300) and system for transmitting sensitive information from a client computer to a service provider operating in the INTERNET. The sensitive information (for example a credit card number for carrying out an e-commerce transaction) is split (318) into several chunks, which are meaningless when taken alone. Each chuck is inserted (339) into a corresponding data frame, adding noise information. Information about how to extract each chunk from the corresponding data frame and how to use the chunks to reconstruct the original sensitive information is inserted (336) into a control frame. The data and control frames are distributed (354, 363) to different interface computers of the INTERNET; the frames are then forwarded (366) to the server computer, which is not connected to the INTERNET directly but communicates through a secure private network with the interface computers.

Abstract: A graphical user interface system for displaying a plurality of icons has a desktop which conceptually provides a three-dimensional surface for the icons. The surface is represented on a two-dimensional display device and navigation of the desktop is supported by simulating a rotation of the surface in three-dimensional space. Furthermore, the desktop is viewed at an apparent distance from a user viewpoint and each of the plurality of icons is viewed at a viewing distance based on the apparent distance and location of each of the plurality of icons on the three-dimensional surface. Additionally, each of the plurality of icons is scaled by the relevant viewing distance. The apparent distance between the viewpoint and the desktop can be changed.
