Next, an example of the illegal copy prevention method will be described with reference to FIG. FIG. 4 is a schematic diagram of an operation when preventing illegal copying in the transaction system shown in FIG.

The original image 401 is image data created by application software on the server 102, and is, as an example in the present embodiment, image data of a ticket which is a product.

The digital copying machine 105 uses the original image 40.
Add an image to 1 with an add-on. The image is, for example, add-on information 402 as an image pattern, which is created by the print driver of the server 102 when the image data created on the server 102 is transferred to the apparatus of this embodiment.

Such add-on information 402 is mainly information for specifying a user. Then, as such add-on information 402, the name of the seller, the name of the ticket issued, the serial number of the digital copying machine 105, the name of the manager, etc., which have been transmitted together with the image data created by the server 102. May be included.

On the other hand, the memory unit 206 of FIG. 2 stores information in which a different number is written for each device in order to specify the device.

Here, the add-on image 403, that is, the one output as a product is an image obtained by adding the above-mentioned add-on information 402 to the original image 401.
Even if 3 is improperly printed or copied, or if it is illegally leaked, follow-up investigation is possible later if the information that identifies the device to which the add-on is added can be specified, and the distribution channel of the image can be identified. It will be possible.

The position where the add-on information 402 is formed is not specified. The add-on information 402 may be hidden depending on the original image 401. Therefore, the same information may be added to a plurality of places like the add-on information 402 shown in FIG.

Next, additional patterns in the transaction system shown in FIG. 1 will be described with reference to FIGS. FIG. 5 is a schematic diagram showing an addition pattern of the add-on information 402 shown in FIG.

In FIG. 5, in the case of 200 line processing,
The 4 × 4 pixels included in the region 501 are modulated so that the gradation of the image signal is, for example, + α.
2 and each of the 2 × 4 pixels included in the region 503 are modulated so that the gradation of the image signal is −α, and the pixels other than the regions 501 to 503 are not modulated.

8 × contained in the regions 501 to 503
Four pixels are set as unit dots of the additional pattern.

In the case of 400 line processing, 4 × 4 pixel processing is performed. In the case of 100-line processing, 2 × 2 or 1 pixel is used as the additional pattern.

Since the following processing method is the same, description will be made by taking 8 × 4 pixels as an example. FIG. 6 is a schematic diagram showing an example of add-on lines in the trading system shown in FIG. 1, and FIG. 7 is a schematic diagram showing an add-on line group in the trading system shown in FIG.

In FIG. 6, reference numeral 601 denotes an add-on line having a width of, for example, 4 pixels. Reference numerals 601a to 601e are unit dots shown in FIG. 5, which are, for example, 8 × 4 pixels. The unit dots 601a to 601e are arranged in the main scanning direction at a substantially constant period of d1 (for example, 128 pixels).

Further, in FIG. 7, reference numerals 701 to 710 are add-on lines having a width of, for example, 4 pixels, which are arranged in the sub-scanning direction at a substantially constant period of d2 (eg, 16 pixels).

As will be described in detail later, for example, one add-online represents 4-bit information, and addon-line 702
~ 709 of 8 add-on-line together, 32
It can represent additional information of bits.

The add-on line is repeatedly formed in the sub-scanning direction. For example, the add-on line 701 shown in FIG.
And 709 represent the same information sequentially and repeatedly.

Next, an example of a method of expressing information by add online in the transaction system shown in FIG. 1 will be described with reference to FIGS. 8 and 9. 8 and 9 are schematic diagrams showing a method of expressing information by add online in the transaction system shown in FIG.

801 and 802 are add-on lines,
Further, 801a, 801b and 802a are unit dots, and in order to prevent adjacent ad-online unit dots from approaching and conspicuous, adjacent ad-online unit dots are at least d3 in the main scanning direction (for example, It is set so that the interval of 32 pixels) is opened.

The data represented by the unit dot is determined by the phase difference between the unit dot 802a and the unit dot 801a.

Although FIG. 8 shows an example of representing 4-bit information, in the example shown in FIG. 8, the unit dot 802a represents data “3”.

For example, if the unit dot 802a is at the leftmost end, data "0" is shown, and if the unit dot 802a is at the rightmost end, data "F" is shown.

In FIG. 9, the add-on line 90 shown in (a) of the set of add-on lines representing all the additional information is shown.
1 is the first add-on line Line 0, and add-on 904 shown in (b) is the fourth add-on line Li.
Represents ne3.

As shown in FIG. 9, in Line 0, d is displayed on the right side of all the original unit dots 901a to 901d.
Dots 902a to 90 at intervals of 4 (for example, 16 pixels)
2d is added, and the original unit dot 9 is added to Line3.
04a-904d to the right of all, d5 (for example, 3
Dots 905a to 905d are added at intervals of 2 pixels.

These additional dots are markers for clarifying the order of each add-on line. The reason why the markers are added to the two add-on lines is that the upper and lower sides in the sub-scanning direction can be determined even from the output image.

Further, for example, if the digital copying machine 105 is in full color, the pattern to be added is Y because the human eye has low discrimination ability with respect to the pattern drawn with Y toner. Only the color information of is added. As a result, when printed out, no additional information is attached.

When this information is added as black information, it is added as a visible image. If the digital copying machine is a black-and-white copying machine, for example, if the density signal has 256 gradations (8 bits), the signal value of about -8 to +8 is used as the add-on information so that it cannot be recognized by human eyes. Add and add.

Further, the dot interval in the main scanning direction of the additional pattern and the repeating interval of all additional information in the sub scanning direction are
It is necessary to determine that all information is surely added to a thin and uniform area where dots can be surely identified in a specific original document.

As a guide, information may be added at a pitch of ½ or less of the width of a thin and uniform area where dots can be surely identified in the target specific document.

Since the Y add-on information and the black density conversion information can be mixed, they can be added at the same position. +4 for add-on pixels, − for surrounding pixels
An example when it is set to 4 will be described with reference to FIG. Figure 10
FIG. 2 is a schematic diagram showing the contents of an add-on information memory in the transaction system shown in FIG. 1.

[0089] It is possible that these additional information was printed out can not be identified visually is to identify whether those output on any device because it is information that can be identified when read by the scanner .

When this is copied, it becomes clear that the illegal copy was made because the device information is added on when the copy is made.

Even if the data on the network is stolen and copied, the add-on data is not included in the data on the network. Therefore, it is possible to determine whether the output is normal by the presence or absence of the add-on.

Next, a method of adding an add-on will be described.
This is done by the circuitry contained within core portion 205 of FIG. This circuit will be described with reference to FIG.
FIG. 11 shows the digital copying machines 105 and 10 shown in FIG.
6 is a block diagram of an add-on circuit included in FIG.

First, the rasterized image signal 1001 is input from the PDL processing section. At this time, add-on data is output in synchronization with the image signal 1101 from the add-on information page memory 1102 in which the add-on information as described above with reference to FIGS.

That is, the add-on information page memory 11
An information format as shown in FIG. 10 is stored inside 02 as add-on data in the 8-bit data format in which the most significant bit is the sign bit in the data of -127 to +127. The part 4 is shown in FIG.
501-503.

Returning to FIG. 11 again, the image signal 1101 and the add-on information page memory 110 read in synchronization with each other.
The add-on data of No. 2 is input to the adder 1103 or the subtractor 1104, and as a countermeasure when it is saturated more than FFH or less than 00H, the carrier signal and the OR gate 1105 or the AND gate 1106 are used.
Through the selector 1107.

Select signal 1108 of selector 1107
Is the most significant bit (sign bit) of the add-on information page memory and is switched depending on whether the add-on information is positive or negative as shown in FIG.

This add-on addition circuit can be added to the YMC and K signal systems, but it would be effective to add-on only to Y for that purpose.

Therefore, if the pattern is written only in the Y page memory, only Y is added.

In the case of black add-on, if an additional pattern is written in the K page memory, the black add-on will be added.

Next, the operation of this embodiment will be described with reference to the flowchart of FIG. FIG. 12 is a flowchart of the operation of the trading system shown in FIG.
