Abstract: A method of providing an electronic business card (EBC) access and organization service on the Web. The cardholder database is accessible and searchable from any browser connected to the Internet or the EBC service may be installed behind a conventional firewall and thus accessible only to intranet users. The service thus provides easy access to cardholder contact information with privacy assured by use of integrated access restrictions. Access to and delivery of contact information by the service is not limited to a Web browser interface as commonly known today. The service provides multi-mode access and/or data delivery interfaces. The service also provides an export feature that formats search results into a pre-defined file structure readable by a conventional contact management programs. Custom export file formats may also be defined provide even wider connectivity and cross-platform utility.

Abstract: A method at a clearing house to verify the geographic region of an end user device for receiving encrypted digital content. In one embodiment the geographic region is a country. The method comprising three sub-methods. In the first sub-method the address is verified by determining the credit card clearing address of the end user using an address verification system. In the second sub-method the address is verified by determining the IP address of the end user device requesting delivery of the encrypted digital content. And in the third sub-method the address is verified by checking that the IP address of the end user device requesting delivery of the encrypted digital content is the identical IP address of the end user device requesting a license to use the encrypted digital content.

Abstract: Copy-protected content material is screened for an indication of the availability of an enhanced version of a screening system and forcing an upgrade to the advanced screening system by refusing to process the copy-protected content material until the upgrade is preformed. When security standards change, and corresponding security techniques are available for downloading to existing consumer devices, newly published content material will contain an indication to that effect. When the newly published content material is processed by an existing consumer device, the consumer device will detect this indication of an available update, and will prevent the processing of this newly published content material until the update is received. In this manner, a phased approach to enhanced security can be effected.

Abstract: Copyrighted software may be executed only on an authorized computer by using a protection mechanism to restrain software to a designated machine. The protection mechanism includes a CIN (Computer Identification Number) reader and a CIN verifier. The CIN reader comprises a function call which reads CINs from the computer where the copyrighted software is intended to execute, and a converter which converts CINs to encrypted CINs. The CIN verifier comprises the encrypted authorized CINs and logic. The CIN may comprise the serial number of a computer chip, the serial number of a hard disk, the serial number of a computer operating system or the like. Protection mechanisms may be integrated into the copyrighted software at stop points by compiling the software source code or revising the executable code of the software. When the resulting protected software is processed on a computer, the protection mechanisms are executed at the stop points.

Abstract: A usage-limit is associated with each copy of copy-protected material. A conforming playback device determines how much usage has been made of the copy, and only plays the copy-protected material if the usage is within the associated usage-limit of the copy. In a preferred embodiment of this invention, the providing source of the copy contains a total-usage-measure that is allocated among each of the provided copies of the copy-protected material, thereby allowing for more than one copy of the copy-protected material to be produced, or “checked-out” from the providing source. When a copy of the copy-protected material is subsequently returned, or “checked-in” to the providing source, the usage allocation associated with this copy is returned to the total-usage-value. In this manner, if a particular copy of the copy-protected material is lost, damaged, or misplaced, the loss of value to the purchaser is merely a reduction in the available total-usage.

Abstract: A method and a system for delivery of protected software applications to remote systems from a central service facility wherein delivery is managed on the basis of the community membership of the remote system user. Business rules are utilized to determine whether a particular authenticated user seeking access to a protected software application from a particular remote site should be authorized. A multiplicity of web servers are programmed to allow selective access to one or more resident software applications by remote system users via a network. Access is managed by a central policy server based on user and system information and community definitions stored in a database. The policy server communicates with each web server via an agency module incorporated in the web server. The agency module intercepts requests for access from remote system users and then interfaces with the policy server.
