The source document is digitized, appropriate locations for embedded code are detected, and any embedded code located in the digitized document along with the detected locations are forwarded to a decoder. The decoder forwards the decoded information to a control unit which processes this information and forwards it to a encoder whereafter it is inserted in the digitized document. The hardcopy replication of the source document being substantially visually identical to the source document, even though new or additional embedded machine-readable data has been added or existing data has been changed. The process occurs without intervention by an operator and without knowledge of the operator producing the replicated documents.
I claim: 1. A quasi-reprographic apparatus comprising: a document input configured to receive and digitize a source document which is in a fixed format; a document storage in operative connection with the document input, configured to store the digitized version of the source document; an embedded code detector in operative connection with the document storage, configured to detect locations in the digitized document appropriate for holding embedded machine readable code and to determine whether embedded machine readable code exists in the digitized document; an embedded code decoder in operative connection with the embedded code detector, configured to decode embedded machine readable code detected by the embedded code detector; a control unit, including a control memory, a processor and a control device, in operative connection with the embedded code decoder, the control unit configured (i) to receive data representing the decoded embedded code and its location in the digitized document, data indicating that no embedded code exists in the digitized document, and data representing an area in the digitized document appropriate for insertion of embedded code, the area appropriate for insertion of the embedded code being an area of uniform color on the source document, (ii) to process the decoded embedded code, (iii) to generate additional data for insertion into the digitized document as embedded code in accordance with instructions stored in the control unit; and (iv) to determine whether the area appropriate for insertion of the embedded code is sufficiently sized to hold the additional data such that the area of uniform color will be visually unaltered upon a hardcopy reproduction of the source document; an embedded code encoder in operative connection with the control unit and the document storage, configured to receive the additional data from the control unit, to transform the additional data into additional embedded code and, to insert the additional embedded code at a selected location in the digitized document; and, an output device for outputting a hardcopy reproduction of the digitized document having the additional embedded code.
2. The quasi-reprographic system according to claim 1 further including a data input device for inputting data to the control unit, for use in processing data received from the embedded code decoder.
8. A method of generating a hardcopy reproduction of a source document using a reprographic apparatus having quasi-reprographic capabilities, comprising the steps of: digitizing the source document; storing the digitized source document in a document storage; detecting locations in the digitized document appropriate for holding embedded machine readable code and determining whether embedded machine readable code exists in the digitized document; decoding embedded machine readable code detected in the determining step; selectively generating information representing (i) detected embedded machine readable code and its location in the digitized document (ii) that no embedded code was detected in the digitized document and (iii) an area appropriate for insertion of embedded code in the digitized document, the area appropriate for insertion of the embedded code being an area of uniform color on the source document; transmitting the selectively generated information to a control unit; processing the transmitted information within the control unit to generate at least one of new and additional data for the digitized document; encoding at least one of the new and additional data into at least one of new and additional embedded code; determining whether or not the area appropriate for insertion of the embedded code is sufficiently sized to hold the new or additional data such that the area of uniform color is visually unaltered upon a hardcopy reproduction of the source document; inserting at least one of the new and additional embedded code at the area appropriate for insertion of the embedded code in the digitized documents when it is determined the area appropriate for insertion of the embedded code is of a sufficient size; and generating a hardcopy reproduction of the source document.
9. The method according to claim 8 wherein the embedded code is a graphical machine readable code.
11. The method according to claim 8 further including: inputting external data to the quasi-reprographic process from a source external to the reprographic apparatus; and using the inputted data in the processing steps to generate at least one of the new and additional data for the digitized document.
12. The method according to claim 8 wherein the step of inserting further includes replacing the embedded code detected in the detecting step with the new or additional embedded code at the location of the replaced embedded code.
16. The method according to claim 8 further including, during the processing step, generating data representing a human readable watermark; encoding the data representing the human readable watermark using the embedded code; and, inserting the generated data, coded with the embedded code, in the digitized document, such that when the hardcopy reproduction is generated, the human readable watermark is generated in addition to any image and data originally on the source document.
17. The method according to claim 16 wherein an appearance of the human readable watermark is altered from a first reproduction of the source document to a second reproduction of the source document.
BACKGROUND OF THE INVENTION This invention relates generally to the copying of a source document on reprographic devices to thereby generate a replication of the source document, and more particularly to embedding and/or altering data during the replication process, whereby the replicated document is substantially visually identical to the source document.
SUMMARY OF THE INVENTION Therefore, in accordance with the present invention, an apparatus and method is provided for quasi-reprographically replicating a source document having or not having embedded machine readable data, wherein the apparatus scans the source document into a digitized bit map, which is then examined for embedded machine readable data and/or for an area suitable for insertion of the embedded data, such as glyph codes. The apparatus codes new data which is to be inputted, and inserts the coded data into the digitized source document at an appropriate location. Thereafter, a hardcopy of the source document is replicated, including the newly added embedded machine readable data, such that the replicated document is substantially visually identical to human viewing.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS While the invention is described in detail herein below with specific reference to an illustrated embodiment and certain applications, it is to be understood that there is no intent to limit to that embodiment or those applications. On the contrary, the aim is to cover all modifications, alternatives and equivalents falling within the spirit and scope of the invention as defined by the appended claims.
FIG. 6 illustrates a source document 80 configured to include a human readable watermark, such as copyright notice, " 1996", 82, located at the bottom of the document. It is appreciated that human readable watermarks are commonly incorporated into a document in a manner more inconspicuous than watermark 82, and also are commonly integrated within text and/or images of the document. Such concepts are taught for example in commonly assigned patent applications to Curry, "Method and Apparatus for Generating Serpentine Halftone Images", U.S. Pat. No. 5,706,099 issued on 6 Jan. 1998. and Curry, "Method and Apparatus for Generating Halftone Images Having Patterns Formed Therein", U.S. Pat. No. 5,710,636 issued on 20 Jan. 1998. both hereby incorporated by reference. Watermark 82 of FIG. 6 is shown more conspicuously and separate from the text and image of document 80' to increase the ease with which the concepts of the present invention may be explained, however, it is to be appreciated the present invention may also be used with inconspicuous incorporated type watermarks.
