Abstract

A system of devices receives and stores documents based on confidential information redacted from the documents. An electronic document is analyzed to identify character blocks having confidential information. The confidential information can be in different formats within the document. Redaction rules are applied to the character blocks to identify confidential categories for the confidential information within the blocks. The confidential information is redacted based on the rules such that the confidential information is removed from the document. A new electronic document is generated with the information redacted such that it is not viewable or printable. The two documents with different levels of confidential information is then stored on separate devices within the system. The documents are transferred when a device is removed from the system according to various criteria.

Claims20

Dependent claims

A system to manage devices comprising:

a plurality of devices comprising a first device having a first security status and a second device having a second security status, wherein the first security status and the second security status relate to a level of confidential information accessible to the first and the second devices, and wherein the first security status is different than the second security status;
a processor in communication with the plurality of devices;
and
a memory coupled to and readable by the processor, the memory storing a set of program instructions which, when executed by the processor, configures the processor to
receive a first electronic document at the first device, wherein the first electronic document includes confidential information related to the first security status;
indicate a first expiration parameter corresponding to the first security status of the first device for the first electronic document;
modify the first electronic document to generate a second electronic document, wherein the second electronic document does not include a portion of the confidential information;
generate a second expiration parameter corresponding to the second security status of the second device for the second electronic document;
store the first electronic document at the first device and the second electronic document at the second device;
remove the first device from the plurality of devices so as to make the first electronic document unavailable according to the first expiration parameter;
remove the second device from the plurality of devices so as to make the second electronic document unavailable according to the second expiration parameter;
determine a third device having the first security status from the plurality of devices, wherein the third device is different than the first device and the second device, wherein the third device is selected from the plurality of devices based on a distance from the first device within a network connecting the plurality of device;
and
transfer the first electronic document to the third device when the first device is removed from the system.

11 more elements

A method for managing documents having confidential information in a system of devices, the method comprising:

receiving a first electronic document at a first device having a first security status, wherein the first security status relates to a level of confidential information in the first electronic document;
indicating a first expiration parameter corresponding to the first security status for the first device that is applicable to the first electronic document;
modifying the first electronic document to generate a second electronic document having a second security status, wherein the second security status relates to a level of confidential information in the second electronic document and wherein the levels of confidential information are different between the first security status and the second security status;
indicating a second expiration parameter corresponding to the second security status that is applicable to the second electronic document;
storing the first electronic document and the second electronic document;
selecting a second device and a third device from the system of devices based on a distance from the first device within a network connecting the system of devices;
transferring the first electronic document to a second device according to an expiration of the first expiration parameter;
transferring the second electronic document to a third device according to an expiration of the second expiration parameter;
and
removing the first device from the plurality of devices so as to make the first electronic document and the second electronic document unavailable at the first device.
