It is most desirable that the registry files of a local computer platform be in instant synchronism with the registry files of a remote backup computer platform. The present invention provides a component object that can monitor a user-specified registry key on a local computer platform and operate to duplicate that registry key, on an instant update basis, at the remote backup platform whenever the local registry key undergoes a change.

System and method for replicating monitored registry keys

In a system where a remote backup platform is enabled to automatically duplicate each registry key change in a local platform, a method is provided wherein restoration of original remote registry key data can be accomplished by utilizing a remote disk file which stores original data. When local original registry data on the local platform is lost to due breakdown, then a restoration program can access the backup remote registry key data for conveyance to the local registry key.

Method for recovery of original registry key file data

A specialized data format native to a first platform is wrap-packaged into an industry-standard text file in a protocol suitable for Internet transmittal. A Signature Support Library provides parameters to combine with a User's private key to generate a signature particular to the data file being converted.

Digital signaturing method and system for packaging specialized native files for open network transport and for burning onto CD-ROM

A method and system is provided whereby after specialized original native format files have been signatured and &ldquo;wrapped&rdquo; into industry standard byte stream text files for transmission over the Internet (or for use of other computer platforms), then subsequently, said wrapped files with signature can be accessed by the proprietary computer platform which will then use the signature to verify the integrity of the files and will unwrap or re-create these files back into the original specialized native format for use by the proprietary computer platform.

Digital signaturing method and system for re-creating specialized native files from single wrapped files imported from an open network or residing on a CD-ROM

A method and system is provided whereby after specialized original native format data files have been signatured and &ldquo;wrapped&rdquo; along with a directory into an industry standard byte stream container file for transmission over the Internet (or for use of other computer platforms), then subsequently, the container of wrapped files with its signature can be accessed by a proprietary computer platform which will then use the signature to verify the integrity of the files and will unwrap or re-create these files back into the original specialized native format for use by the proprietary computer platform.

Digital signaturing method and system for re-creating specialized native files out of a container imported from an open network or residing on a CD-ROM

A container of data files and directory in a specialized first format are converted (wrapped) into an industry-standard text container file into a protocol suitable for Internet transmittal. A Signature Support Library and several procedural routines, together with parameters from the Support Library are utilized to combine with a user's private key to generate a signature particular to the container data file which has been converted. The container now with signature resides in a protocol suitable for transmission on the Internet or for burning onto a CD-ROM which is now usable for different platforms other than the original file protocol of a first platform which was only compatible with said specialized first format of the first platform.
