<p>A system providing a publicly-accessible, independent, and secure host internet site that provides a downloadable agent program to any anonymous client PC, with the agent program generating within the client PC a registration checksum based upon the document to be registered. The checksum is then uploaded to and archived by the host as a verifiable record, without transmission of the document to be registered, and without a requirement for identification of the client. In addition, the host in addition generates a registration number, and may generate a registration certificate, both downloadable to the client. This registration can be used to verify the integrity of document with respect to date, time, and content of the document at any later date and time and by any client with access to both the document and the registration number. If desired, a transaction fee may be charged to the registering client, as well as to either the original registering client or the validating client at the time of validation. Last, if a digital signature is provided by the registering client, this can be appended in a verifiable manner to the host registry. A method for the system is also described.</p> |
