Group telemetry analysis using the World Wide Web Page: 7 of 9

scan all access control information and present the authenticated user with a list of all
possible files he may access. The user may then decide whether to select all files, or
only a subset.
Once the files of interest are selected, the user must indicate a desired return format for
the data (e.g. HTML table, space delimited ASCII file, etc.) and a return MIME type
which will allow the secure client browser's helper application to detect data returned
from the server. Typically, the helper application will merely collect data and place it in
a format so it might be processed by an On Line Analytical Processing (OLAP) tool on
the client platform.
Advanced Concepts
With the emergence of "plug-ins" (like a helper application, except the plug-in
communicates with the client browser via a programmatic API), the possibility exists to
create an entire telemetry post processing environment that can be accessed through the
web browser. One can also conceive of creating JAVA applets that could perform
specific analytical functions on returned data. These applets could be offered by the
server holding data to be analyzed. Finally, access control functions could be expanded
to allow analysts to place post processed data back onto the server so specified
individuals could gain access to the analysis results.
Conclusions
The technology is now in place for geographically remote development teams to
perform analysis on a sensitive telemetry product using S-HTTP/SSL client/servers on
the Internet. Server CGI programs are the key to managing the data product securely;
while client helper applications assure that data accessed can be stored and presented
on the analysts local computer.
