Abstract

This article describes security enhancements to the handwritten annotation subsystem described in the preceding article. These enhancements enable a user of the subsystem to specify the identity or the authorization level of the individual or individuals to whom the user's handwritten annotation is directed, and where appropriate, they also may qualify or restrict a user's ability to create or view annotations according to the identity or authorization level of the user. An authorized user also may query the subsystem for information regarding the origin of an annotation and the users who are permitted access to it.

Enhanced Handwritten Annotation of Electronic Documents

This article describes security enhancements to the handwritten annotation subsystem described in the preceding article. These enhancements enable a user of the subsystem to specify the identity or the authorization level of the individual or individuals to whom the user's handwritten annotation is directed, and where appropriate, they also may qualify or restrict a user's ability to create or view annotations according to the identity or authorization level of the user. An authorized user also may query the subsystem for information regarding the origin of an annotation and the users who are permitted access to it.

The office system to which these enhancements relate is illustrated above and is basically the same system as that shown in the preceding article. To support these enhancements, the system software must be capable of distinguishing user IDs (UIDs) and also the authorization levels (ALs) associated with users. Each user has a unique UID and a certain range or ranges of ALs, which together determine the document annotations to which the user can have access and the individuals or classes of individuals to whom he can direct annotations.

In the present enhancement version, the annotation subsystem, comprising the interface and the associated save task and tablet task, has a modified "create an annotation" function and two new query functions, the purpose of which is explained below. Each of these modified and new functions entails a control upon the passage of annotation information in accordance with the UID or AL of the user or the recipient(s) to whom his annotation is directed. In the document structure, as presently constituted, the information for each annotation includes the originator UID, the date and time of origination, and the recipient UID or AL.

The effects of some of the commands described in the preceding article have been modified in the present version, as indicated below:

Initialize annotation subsystem:

The application provides the UID and the user's

authorization range(s), as well as the mapping

information and display plane. The interface sets up

the tablet and save tasks, and saves the UID for use in

annotation creation. It checks the UID and

authorization range(s) against the recipient

information of all existing annotations as their

information is read from the data area. Only those

annotations which the user is authorized to see are

included in the list which the interface maintains.

Create an annotation:

The user must in some manner indicate the specific

individual or class of individuals (by UID or AL) to

which the annotation is directed. The application

supplies this recipient UID or AL to the interface and

indicates the display area valid for annotation. The

interface places the tablet task in the annotation
