Abstract
Abstract A server (A) has a database (12A) in which a number of documents are stored. The server (A) is accessible by many distant user terminals (20A..20N), for example via the internet. The documents may be in HTML form for distribution through the World Wide Web. Each document is assigned a security level and different documents may have different security levels on a document by document basis. The database (12A) includes a table containing a user name, a password and a security level indicator. When a particular document is requested by a user terminal (20A) the security level of the user is determined from the table and access to the document is allowed only if the security level of the requesting user is as least as high as the security level of the requested document.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
71 words
A document security system comprising a server
(12A) in which a plurality of documents are stored for
access by user terminals (20A..20N) characterised in that a database (A) is provided in the server (12A), which
database (A) has: means for storing user information
(110,120,130,140,150); means for storing document
information (210,220,230,240); and means for providing
access to the stored documents document-by-document on the
basis of the user information and the document information.
Claim 2
Dependent Claim
49 words
The system according to claim 1 wherein the said
means for storing user information includes means for
storing a user identification name (110), an associated user
password (130) and an associated security level indicator
(140) for indicating the highest level of security access
for the user name associated therewith.
Claim 3
Independent Claim
58 words
The system according to either one of the
preceding claims wherein the said means for storing document
information includes a file name (230), code means for
creating a document (240) associated with the file name
(230) and a security level indicator (210) associated with
the file name (230) for indicating the security level of the
associated document (230).
Claim 4
Independent Claim

The system according to any one of the preceding
claims wherein the said means for providing access to stored
documents is included in a common gateway interface file
(CGI-A..CGI-N).

A method of providing document security in an
environment where a server stores a plurality of documents
and the server is accessible by any of a plurality of user
terminals comprising the steps of: assigning a security level to each document, assigning a security level to each user terminal, receiving a request at the server from a user terminal
for access to a document, determining the security level assigned to the user
terminal, comparing the determined security level with the
security level assigned to the requested document, and providing access to the requested document only if the
result of the comparison step indicates that the security
level of the said user terminal is at least as high as the
security level assigned to the requested document.
Claim 7
