Abstract
Abstract Limited printing of a source document (11) is performed. The source document (11) is encrypted to produce an encrypted document (15). The encrypted document (15) is combined with program objects (16) to form a limited print document (18). The limited print document (18) is received by a user. Upon the user executing the limited print document (18), the program objects (16) are run. The program objects (16) oversee decryption of the encrypted document (15) and printing the source document (11) on a printer (41).

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
94 words
A method for providing for limited printing of a
source document (11), the method comprising the following
steps: (a) encrypting the source document (11) to produce an
encrypted document (15); (b) combining the encrypted document (15) with program
objects (16) to form a limited print document (18); (c) receiving the limited print document (18) by a
user; and, (d) running the program objects (16) upon the user
executing the limited print document (18), the program
objects (16) overseeing decryption of the encrypted document
(15) and printing the source document (11) on a printer
(41).
Claim 2
Dependent Claim
129 words
A method as in claim 1 wherein in step (d) upon
running the program objects (16), the following substeps are
performed: (d.1) using an installation identifier (26) to confirm
permission to print the source document (11), including the
following substeps: forwarding the installation identifier (26)
through the internet (22) to a document provider, checking the installation identifier (26) by the
document provider against information stored in a database
(31), and forwarding by the document provider to the program
objects (16) an indication as to whether permission is
confirmed; and, (d.2) upon confirmation of permission to print the
source document (11), performing the following substeps: decrypting the encrypted document (15), printing the source document (11) on the printer
(41), and upon completion of printing, destroying the
limited print document (18).
Claim 3
Dependent Claim
101 words
A method as in claim 1 wherein in step (d) upon
running the program objects (16), the following substeps are
performed: (d.1) using an installation identifier (26) to confirm
permission to print the source document (11), including the
following substep: comparing the installation identifier (26) with
identification information pertaining to a computing system
on which the programming object is running to determine
whether a computing system on which the program objects (16)
are running is authorized to perform a print; and, (d.2) upon confirmation of permission to print the
source document (11), printing the source document (11) on
the printer (41).
Claim 4
Dependent Claim
26 words
A method as in claim 1 wherein in step (c) includes
the following substeps: (c.1) purchasing, by the user, rights to print the
source document (11).
Claim 5
Dependent Claim
43 words
A method as in claim 1 wherein in step (c)includes
the following substeps: (c.1) receiving, by the user, a decryption key to be
used for decrypting the encrypted document (15) in response
to the user purchasing rights to print the source document
(11).
Claim 6
Dependent Claim
46 words
A limited print document (18) comprising: an encrypted document (15) that when decrypted is a
source document (11); and, program objects (16) which when run on a computing
system oversee decryption of the encrypted document (15) and
printing the source document (11) on a printer (41).
Claim 7
Dependent Claim
68 words
A limited print document (18) as in claim 6
wherein the program objects (16) use an installation
identifier (26) to confirm permission to print the source
document (11), and upon confirmation of permission to print
the source document (11), decrypting the encrypted document
(15), printing the source document (11) on the printer (41),
and upon completion of printing the program objects (16),
destroying the limited print document (18).
Claim 8
Dependent Claim
57 words
A limited print document (18) as in claim 6
wherein the program objects (16) use an installation
identifier (26) to confirm permission to print the source
document (11), forwarding the installation identifier (26)
through the internet (22) to a document provider to
determine whether there exists permission to print the
source document (11) on the printer (41).
Claim 9
Dependent Claim
73 words
A limited print document (18) as in claim 6
wherein the program objects (16)use an installation
identifier (26) to confirm permission to print the source
document (11) by comparing the installation identifier (26)
with identification information pertaining to a computing
system on which the programming object is running to
determine whether a computing system on which the program
objects (16) are running is authorized to perform a print of
the source document (11).
Claim 10
Dependent Claim
44 words
A limited print document (18) as in claim 6
wherein the program objects (16) use a decryption key to be
used for decrypting the encrypted document (15), the
decryption key being received in response to purchasing of
rights to print the source document (11).
