Abstract: A system for detecting real-time system file intrusions in a user computer that is coupled to an administrator computer and includes an operating system and system files. At a boot time of the user computer, an application program interface (API) of the operating system receives a list of vital system files that consists of at least two directory files. At the boot time, one of more daemons are launched, after which the API detects one or more system calls made to one or more vital system files. The API raises an automatic interrupt ‘I’ command that awakens a daemon from a sleep mode. The awakened daemon catches the interrupt ‘I’ command and sends an alert message to the administrator computer to alert the administrator computer of the detecting of the system call made to the one or more vital system files.

Abstract: A method for on-line processing of electronic commercial transactions using three distinct communication networks to enhance the security of sensitive information such as credit card numbers.

Abstract: A method and healing system for healing a computer's vital files. The healing system includes a system healer having a database that stores a copy of the computer's vital files. The system healer receives identification of condition(s) under which a first vital file is to be changed. The system healer receives notification that the computer has detected a change in the first vital file. If the system healer ascertains that the condition(s) are satisfied, then the system healer replaces the stored copy of the first vital file by the changed first vital file in the system healer's database. If the system healer ascertains that the condition(s) are not satisfied then the system healer sends the stored copy of the first vital to the computer, resulting in replacement of the changed first vital file in the computer by the stored copy of the first vital file.

Abstract: A tactile interface system is disclosed comprising a information transmission unit and a tactile interface. The information transmission unit may be located in any information system and transmits information for reception by the tactile interface. The tactile interface has a plurality of tactile character reproduction devices which are controlled by a reception unit to reproduce the information transmitted by the information transmission unit to a user of the tactile interface. In a preferred embodiment the tactile interface is a Braille interface.
