Abstract

Disclosed is a method and system for a differential shredder that comprises a paper shredder operational mode and an automatic assessment of document sensitivity (e.g., confidentiality). Based on said sensitivity, the operational mode automatically changes the operational mode that best suits the security level of the documents.

Cognitive and Contextual Paper Shredder

Numerous standards are set for the security levels of paper shredders , which are marked by rules for shreds to be of certain sizes (i.e., length and width) depending on the level of security needed for the document . Paper shredding systems and services include mobile shredding trucks, public kiosks, and services that secure the documents and then perform the shredding either on- or offsite. None of these methods performs an automatic assessment of document sensitivity to ensure secure shredding practices .

The novel contribution is a differential shredder . The method and system comprise a paper shredder operational mode and an automatic assessment of document sensitivity. The sensitivity assessment is based on a rapid optical scanning of document. The operational mode may control characteristics of shredding , degree of shredding, type of shredding, burning, etc. Based on document sensitivity, the system changes operational mode.

With this novel system for a cognitive and contextual paper shredder , the degree of shredding may depend on the sensitivity of the document . The sensitivity can be automatically estimated or be aided by user input. For less sensitive documents, the user might want a fast shred (but not as complete) to reduce completion time.

Automatic burning may be invoked for the most confidential materials .

This shredder system might also have energy implications; coarse vs. fine shredding differences may relate to speed and the duration the device is shredding , so that more paper can be quickly shredded in coarse mode. Energy usage could be lower in coarse mode, especially if it takes less time. Alternatively, in coarse mode, the shredding blades may last longer than in fine mode.

Another novel feature relates to specific items to which the scanner is sensitive . For example, a social security number recognition engine can trigger the fine shredder mode when identified to reduce the chances of identity fraud . The engine can scan the document looking for nine-digit numbers, three sets of three numbers separated by hyphens, which indicates a social security number. Bank account numbers and credit card numbers can similarly trigger fine-grained shredding. In addition, the optical scanning element may sense the presence of images , and these may be used to guide the nature of shredding.

The system may consider the time of the day (when is a user depositing papers for shredding) and where (in which location) -- for additional criteria used to estimate a needed level of shredding. Some images might include personal or sensitive photographs that might embarrass the document owner if not shredded finely enough . The system may even be set to locate or recognized certain images (e.g., the face of a user).

Additional compartments may be used for the shredder , such that different-sensitivity debr...
