Abstract
The disclosed embodiments provide for checking documents for security compliance when the documents are printed, scanned, or copied. A security status is determined based on security indicators within a document's content. Security indicators can be located within a document's text, figures, watermarks, security marks, and invisible marks. Security indicators can be found by comparing a document's content to a set of stored indicator descriptions. The indicators found are used to determine a document score and security responses are triggered based on the document score.
Claims20
A method comprising:
- obtaining a plurality of security levels wherein the security levels are predefined and stored within a document printing system;
- storing a plurality of security specifications within the document printing system wherein each security specification associates at least one of the security levels with at least one of a plurality of indicator descriptions;
- storing a plurality of security rules within the document printing system wherein the security rules relate a plurality of security responses with a plurality of possible security levels;
- receiving at least one instruction for amending the security rules in conformance with the at least one instruction;
- receiving a document description from a communications network, the document description comprising at least one security indicator matching one of the indicator descriptions and wherein a document description input comprises a communications interface that receives an additional document description from the communications network;
- determining that the document description comprises at least one security indicator and producing a document score based at least in part on those of the security levels associated with those of the indicator descriptions matching the at least one security indicator and also at least in part on the location of a printing subsystem, wherein the document score comprises a list of the indicator descriptions matching the at least one security indicator;
- triggering at least one of the security responses based on the document score, and the security rules, an operation type indicating an operation currently being attempted, a user identifier indicating the person attempting the operation, wherein the security response is selected from a plurality of security responses;
- and
- printing, by the printing subsystem, text, images, and other markings onto sheets of printable media.

A document printing system that manages document security and that prints text, images, and other markings onto sheets of printable media comprising:
- a plurality of security levels wherein the security levels are predefined and stored within the document printing system;
- a printing subsystem that prints the text, the images, and the other markings onto the sheets of printable media;
- a plurality of security specifications wherein each security specification associates at least one of the security levels with at least one of a plurality of indicator descriptions, and wherein the document printing system stores the security specifications within the document printing system;
- a plurality of security rules that relate a plurality of security responses with a plurality of possible security levels, and wherein the document printing system stores the security rules within the document printing system;
- a document description input that receives a document description comprising at least one security indicator matching one of the indicator descriptions wherein the document description input further comprises a communications interface that receives an additional document description from a communications network;
- wherein the document printing system determines that the document description comprises at least one security indicator and produces a document score based on those of the security levels associated with those of the indicator descriptions matching the at least one security indicator, wherein the document score comprises a list of the indicator descriptions matching the at least one security indicator;
- and
- wherein the document printing system triggers at least one of the security responses based on the document score, the security rules, an operation type indicating an operation currently being attempted, and a user identifier indicating the person attempting the operation;
- wherein the security response is selected from a plurality of security responses.
6 more elements
The document printing system of claim wherein the security response comprise obtaining video or an image.
A non-transitory processor-readable medium storing code representing instructions to cause a processor to perform a process, the code comprising code to:
- read a plurality of security levels wherein the security levels are predefined and stored within a document printing system;
- store a plurality of security specifications wherein each security specification associates at least one of the security levels with at least one of a plurality of indicator descriptions;
- specify at least one of a plurality of security rules that relate a plurality of security responses with a plurality of possible security levels;
- receive a document description comprising at least one security indicator matching one of the indicator descriptions wherein a document description input further comprises a communications interface that receives an additional document description from a communications network;
- determine that the document description comprises at least one security indicator;
- produce a document score based at least in part on those of the security levels associated with those of the indicator descriptions matching the at least one security indicator and also based at least in part on the geolocation of a printer wherein the document score comprises a list of the indicator descriptions matching the at least one security indicator;
- trigger a security response based on the document score, the security rules, an operation type indicating an operation currently being attempted, a user identifier indicating the person attempting the operation wherein the security response is selected from a plurality of security responses, the security responses comprising:
- allow operation, refuse the operation, and obtain image or video;
- and
- command the printer to print a document based on the document description.
