Embedded document destination routing restrictions
View Patent ↗Embodiments of the present invention provide a method, system and computer program product for restricting transmission of a document. In an embodiment of the invention, a method for restricting transmission of a document is provided. The method includes loading an image of a document into memory of a computer, receiving a request to transmit the image to a specified destination, and in response to receiving the request, locating an embedded code within the document, extracting a restriction as to the transmission of the image of the document, applying the restriction, and transmitting the image of the document to the specified destination only if permitted by the restriction.
1. A method for restricting transmission of a document, the method comprising:
loading an image of a document into memory of a computer;
receiving a request to transmit the image to a specified destination; and,
in response to receiving the request, locating an embedded code within the document, extracting a restriction as to the transmission of the image of the document, the restriction specifying a time of day or date during which the image is either permitted or prohibited to be transmitted, applying the restriction, and transmitting the image of the document to the specified destination only if permitted by the restriction.
2. The method of claim 1 , wherein the embedded code is embedded within text of the image of the document.
3. The method of claim 1 , wherein the restriction specifies a destination either permitted or prohibited to receive a transmission of the image.
4. The method of claim 1 , further comprising updating the embedded code with the specified destination.
5. The method of claim 1 , further comprising:
detecting a checksum code in the image of the document;
computing a checksum of the image of the document;
comparing the checksum code to the computed checksum; and,
triggering an error condition in response to a failure of the checksum code and the computed checksum to match.
6. A document transmission data processing system comprising:
a host computing platform comprising at least one processor, memory, fixed storage and a display;
a document image processor executing in the memory and configured to load into memory an image of a document and transmit the image to a specified destination; and,
a document restrictions module coupled to the document image processor, the module comprising program code enabled to respond to a request in the document image processor to transmit the image of the document by locating an embedded code within the document, extracting a restriction as to the transmission of the image of the document, the restriction specifying a time of day or date during which the image is either permitted or prohibited to be transmitted, applying the restriction, and directing the document image processor to transmit the image of the document to the specified destination only if permitted by the restriction.
7. The system of claim 6 , wherein the computer is included as part of a facsimile device.
8. The system of claim 6 , wherein the image is a facsimile of a document.
9. The system of claim 6 , wherein the embedded code is embedded within text of the image of the document.
10. The system of claim 6 , wherein the restriction specifies a destination either permitted or prohibited to receive a transmission of the image.
11. The system of claim 6 , wherein the program code is further enabled to update the embedded code with the specified destination.
12. The system of claim 6 , wherein the program code is further enabled to:
detect a checksum code in the image of the document;
compute a checksum of the image of the document;
compare the checksum code to the computed checksum; and,
trigger an error condition in response to a failure of the checksum code and the computed checksum to match.
13. A computer program product for restricting transmission of a document, the computer program product comprising:
a computer readable storage memory device having computer readable program code embodied therewith, the computer readable program code comprising:
computer readable program code for loading an image of a document into memory of a computer;
computer readable program code for receiving a request to transmit the image to a specified destination; and,
computer readable program code for responding to receiving the request by locating an embedded code within the document, extracting a restriction as to the transmission of the image of the document, the restriction specifying a time of day or date during which the image is either permitted or prohibited to be transmitted, applying the restriction, and transmitting the image of the document to the specified destination only if permitted by the restriction.
14. The computer program product of claim 13 , wherein the embedded code is embedded within text of the image of the document.
15. The computer program product of claim 13 , wherein the restriction specifies a destination either permitted or prohibited to receive a transmission of the image.
16. The computer program product of claim 13 , further comprising computer readable program code for updating the embedded code with the specified destination.
17. The computer program product of claim 13 , further comprising:
computer readable program code for detecting a checksum code in the image of the document;
computer readable program code for computing a checksum of the image of the document;
computer readable program code for comparing the checksum code to the computed checksum; and,
computer readable program code for triggering an error condition in response to a failure of the checksum code and the computed checksum to match.
