Abstract: A method and system for providing remote access to the facilities of a server computer are provided. A site integration application programming interface at a co-branded Web site. The site integration application programming interface exposes a number of servlets that may be executed in response to requests received from a business partner Web site over a secure communications link. The servlets provide functionality for accessing the user registration and deletion facilities of the co-branded Web site. Moreover, the servlets also provide access to other administrative facilities provided at the co-branded Web site. The servlets also provide functionality for authorizing a user to access the co-branded we site. This servlet may be executed in conjunction with the login facilities of the business partner web site to permit concurrent login at both sites.

Abstract: A method and system is presented for a digital licensing scheme that separates the license from the digital file containing the copyrightable material. According to the present invention, the files can be downloaded from any server, and transferred from user to user, even after the file has been licensed. The present invention utilizes producer software running on a vendor's computer, server software running on a computer provided by the license provider, and player software operating on the user's computer. Digitally encrypted communication streams keep communications between the producer software, the license provider, and the player software confidential. A software component running on the user's computer checks to make sure that the appropriate product license has been purchased. This is accomplished by comparing the product ID in the product license with the product ID contained in the product file.

Abstract: A system and method distribute licenses for copyrighted material separate from the copyrighted material itself. A producer or “vendor” of copyrighted material registers the material with a License Provider. The License Provider returns an encryption code for the producer to attach to the materials which are in digital form. The vendor distributes that material to one or more users who purchase a license from the License Provider. The license includes an encryption key to decrypt the file containing the materials. The system and method incorporate security measures to prevent unlicensed use and distribution of the materials.

Abstract: A system and method provide digital tokens for use in e-commerce. The tokens are transferable and can be purchased for another person to spend. Such tokens are of particular use in a system and method to distribute licenses for copyrighted material separate from the copyrighted material itself.

Abstract: A method and system is presented for storing multiple tracks of music in a single structured storage file having multiple layers of organization. The top layer contains links to separate “folders” for each track, as well information associated with the collection of tracks as a whole. Inside each track folder is the digital data defining the music track, as well as information concerning that track. Audio/video information associated with the collection can be stored in the root file, while audio/video information associated with the track is stored in the track folder. A file header in the root directory contains a vendor ID and a product ID, which allows licensing software to examine the file and uniquely associate it with a particular license. Preview tracks contained in the track folders can be played if the no license exists. To prevent tampering with the product or vendor ID, the header file is encrypted with DES encryption using an encryption key common to all files.

Abstract: Briefly, in accordance with one embodiment of the invention, a method of using a digital signature includes: electronically referencing at least one plurality of electronic signals with a digital signature remotely stored from the plurality.

Abstract: A method and apparatus of communicating information comprising providing a datum which includes a digital certificate containing data. The digital certificate including an extension which includes: a first identifier which specifies a major classification of the data; a second identifier which specifies a minor classification of the data; and data in a format according to the major classification and the minor classification, the data indicating an owner of the datum and a use for which the datum is intended. The certificate allows authentication of the certificate itself and the data contained therein, and the data contained in the certificate can include information allowing verification of the identity of the holder of the certificate.
