Abstract
Provided is a device that prevents unauthorized copying of a document to which copy inhibition information is added.
Claims12
A device comprising:
- a generating unit configured to read a plurality of documents and generate document images corresponding to the documents;
- and
- an extracting unit capable of extracting conditional output permission information and output inhibition information from the generated document images,
- wherein if the conditional output permission information and the output inhibition information are extracted by the extracting unit, the generated document images are not output.
A device comprising:
- a generating unit configured to read a plurality of documents and generate document images corresponding to the documents;
- and
- a detecting unit capable of detecting an image that represents conditional output permission information and an image that represents output inhibition information from the generated document images,
- wherein if the image that represents the conditional output permission information and the image that represents the output inhibition information are detected by the detecting unit, the generated document images are not output.
A method of controlling a device, comprising:
- a generating step, performed by a generating unit, of reading a plurality of documents and generating document images corresponding to the documents;
- and
- an extracting step, performed by an extracting unit, of extracting conditional output permission information and output inhibition information from the generated document images,
- wherein if the conditional output permission information and the output inhibition information are extracted in the extracting step, the generated document images are not output.
A device capable of reading a document on a document plate, the device comprising:
- a printing unit, the printing unit configured to create a first document by printing an embedded image that is generated if the user selects a first option to inhibit copying, and a second document by printing an embedded image that is generated if the user selects a second option to permit copying and then inputs a password,
- wherein if a copy start instruction is given by the user after the first document and the second document are put on the document plate, a screen to request the user to input a password is not displayed, and the printing unit does not print images acquired by reading the first and second documents,
- wherein if a copy start instruction is given by the user after the first document is put on the document plate, the printing unit does not print an image acquired by reading the first document,
- wherein if a copy start instruction is given by the user after the second document is put on the document plate, the screen to request the user to input a password is displayed,
- wherein the printing unit prints the image acquired by reading the second document, if the password input by the user matches with the password input when the second document is created by the printing unit,
- wherein the printing unit does not print the image acquired by reading the second document, if the password input by the user does not match with the password input when the second document is created by the printing unit, and
- wherein if a copy start instruction is given by the user after the second document, and another document which has been created separately from the second document by printing another embedded image that is generated when the user has selected the second option and then input a password, are put on the document plate, the screen to request the user to input a password is not displayed, and the printing unit does not print images acquired by reading the second document and the another document.
A method of controlling a device capable of reading a document on a document plate, the device including a printing unit, the printing unit configured to create a first document by printing an embedded image that is generated if the user selects a first option to inhibit copying, and a second document by printing an embedded image that is generated if the user selects a second option to permit copying and then inputs a password, the method comprising the steps of:
- if a copy start instruction is given by the user after the first document and the second document are put on the document plate, not displaying a screen to request the user to input a password, and not causing the printing unit to print images acquired by reading the first and second documents;
- if a copy start instruction is given by the user after the first document is put on the document plate, not causing the printing unit to print an image acquired by reading the first document;
- if a copy start instruction is given by the user after the second document is put on the document plate, displaying the screen to request the user to input a password;
- causing the printing unit to print the image acquired by reading the second document, if the password input by the user matches with the password input when the second document is created by the printing unit;
- not causing the printing unit to print the image acquired by reading the second document, if the password input by the user does not match with the password input when the second document is created by the printing unit;
- and
- if a copy start instruction is given by the user after the second document, and another document which has been created separately from the second document by printing another embedded image that is generated when the user has selected the second option and then input a password, are put on the document plate, not displaying the screen to request the user to input a password, and not causing the printing unit to print images acquired by reading the second document and the another document.
