Origin and custody of copies from a stored electronic record verified page by page

摘要

A method of authenticating a copy of a multi-page document, which includes digitizing a said multi-page document to generate one or more digitized files that together comprise a digitized transcript. A mark that is unique to the preparer of the document, such as a signature, is prepared and digitized. The preparer of the document is allowed to deposit the digitized transcript on an online repository. The operator of the online repository immediately establishes a verification process for the deposited digitized transcript. This verification process includes associating the digitized preparer mark with the deposited digitized transcript, and freezing the transcript, by encrypting it and deriving a checksum. The verification process also include associating a repository mark with the transcript. The operator of the online repository defines, under the direction of at least the preparer of the document, security rights to limit or otherwise control access to the deposited digitized transcript. The digitized preparer mark and the digitized repository mark are allowed to appear on substantially all copies of the pages of the document only if the pages have not been altered. If carrying out the verification process verifies that the deposited digitized transcript has not been changed since the verification process was established the marks are displayed with the unaltered page. This display whether the pages are displayed on a monitor or printed in paper form. Each page with this display is thus authenticated as to origin and custody apart from the other pages or the transcript as a whole.

主权项

1. A digitized electronic record stored on a repository, said digitized electronic record comprising:
a plurality of substantive pages, substantially all of said substantive pages being associated with an originator mark and a custodian mark, said originator mark being adapted to reflect that the digitized electronic record was accurate when created and said custodian mark being adapted to affirmatively reflect that said digitized electronic record has not changed while on said repository; and a security protocol imposed on said digitized electronic record by said repository, said security protocol being adapted to permitting individual ones of said substantive pages to be reproduced at a location remote from said repository with said custodian and originator marks displayed thereon only if such reproduced substantive pages have not been changed since said custodian and originator marks were associated with said digitized electronic record; wherein said originator mark and said custodian mark are independently visually perceptible upon viewing of each of such reproduced substantive pages.
