Collaborative email with delegable authorities

Collaborative email with delegable authorities description/claims

This application is a continuation application of and claims priority from U.S. patent application Ser. No. 10/835,336, filed on Apr. 29, 2004 which is a continuation-in-part of a co-pending US patent application entitled “COLLABORATIVE EMAIL,” having Ser. No. 10/637,020 (Attorney Docket No. AUS920030500US1) and filing date of Aug. 7, 2003.

1. Field of the Invention

The field of the invention is data processing, or, more specifically, methods, systems, and products for collaborative email with delegable authorities.

2. Description of Related Art

Systems for collaboration in developing email documents generally maintain a master copy of a document in a central location, record changes in the master copy, and update collaborators' copies by providing a new copy of the entire document. This uses a lot of bandwidth, particularly when there are many revisions over a period of time. There are version control systems, such as Unix's Source Code Control System or ‘SCCS’ and the open-source version control system known as the Concurrent Versions System or ‘CVS.’ Such systems are strongly oriented to version control for source code documents, however, and do not integrate very well with collaborative email, lacking, as they do, support for such collaborative features as automated updates to certain revision levels or authentication through valid digital signatures and delegable authorities for signing, viewing, and editing collaborative email documents. For these reasons, there is an ongoing need for improvements in systems and methods for collaborative email.

Method, systems, and products are disclosed for writing a collaborative email document with hierarchical authorities including establishing a collaborative email document on an administrator's computer, identifying one or more signatories for the document, identifying one or more collaborators who are authorized to view and edit the document, providing to the collaborators copies of the document for viewing and editing, where the collaborators' copies reside on collaborators' computers, updating the copies of the document on collaborators' computers with revisions from the collaborators, and sending the collaborative email document from the administrator's computer to addressees when the document bears valid digital signatures from all signatories. Typical embodiments also include providing to at least one user authority to delegate signature authority. Typical embodiments also include establishing a hierarchy of delegation authority for signatures, establishing at least one authority delegation policy including at least one rule for automated delegation of signature authority among signatories in the hierarchy, and delegating signature authority from at least one signatory to another signatory in accordance with the authority delegation policy. Typical embodiments also include establishing at least one authority delegation policy including at least one rule for automated delegation of signature authority, and delegating signature authority from at least one signatory to another signatory in accordance with the authority delegation policy.

In typical embodiments include rules for automated delegation of signature authority including a rule that the signature authority of a first signatory having a first position in a hierarchy of delegation authority may be delegated to a second signatory having a second position in the hierarchy of delegation authority, where the second position is higher in the hierarchy than the first position, a rule that a first signatory having a first position in the hierarchy of delegation authority may digitally sign the collaborative email document only after a second signatory having a second position in the hierarchy of delegation authority has signed the collaborative email document, where the second position is higher in the hierarchy than the first position, a rule that signature authority is to be delegated to a second signatory if a first signatory does not sign the document within a specified period of time, and a rule that signature authority may be delegated during a specified period of time. Typical embodiments include establishing one or more authority delegation type parameters that identify modes of delegating authority for signatories, assigning at least one authority delegation type parameter to the collaborative email document, and delegating signature authority from at least one signatory to another signatory in accordance with the assigned authority delegation type parameter.

Typical embodiments' modes of delegating authority for signatories include a mode in which signature authority is delegated according to authority delegation policies, a mode in which signature authority is delegated by an originator of the collaborative email document, and a mode in which one or more collaborators are authorized to delegate signature authority to at least one signatory. Typical embodiments also include establishing time parameters for writing the collaborative email document, providing alerts and reminders in accordance with the established time parameters, and forwarding copies of the collaborative email document to delegated backup collaborators in accordance with the established time parameters.

Typical embodiments also include providing for at least one collaborator authority to delegate the authority to view and edit the collaborative email document. Typical embodiments also include identifying editable portions of the email document, and specifying that only certain collaborators are authorized to view and edit one or more portions of the document, where authority to view and edit one or more portions of the document includes authority to delegate to another collaborator the authority to view and edit one or more portions of the document.
