| 20090100946 | Secure resource tracker - A system for tracking resource parameters includes a resource having an associated memory tag; a parameter sensing element sensing a parameter of the resource; and a memory tag reader/writer. The system is configured to store information gathered from the parameter sensing element on the memory tag. | 04-23-2009 |
| 20110246539 | Document Modeling Using Concurrent Hierarchical State Machines - A document having a number of components is modeled as a concurrent hierarchical state machine derived from a number of secondary state machines. The concurrent hierarchical state machine hierarchically encompasses the secondary state machines and corresponds to the document as a whole. The secondary state machines are concurrent to one another. Each secondary state machine corresponds to one of the components of the document. | 10-06-2011 |
| 20120131351 | MANAGING ACCESS TO A SECURE DIGITAL DOCUMENT - In a method for managing access to a secure digital document by workflow participants, in which a respective public key is associated with each of the workflow participants, an entry table is populated with a participant entry for each of the workflow participants. Each of the participant entries includes a map entry identifier that corresponds to a map entry tag in a map file, and a first label associated with the map entry identifier. In addition, symmetric keys for the workflow participants are accessed and each of the first labels is encrypted using a respective symmetric key to generate a plurality of second labels, the entry table is populated with the plurality of second labels, each of the plurality of symmetric keys is encrypted with the public key of a respective workflow participant, and the entry table is incorporated into the digital document. | 05-24-2012 |
| 20120185701 | DOCUMENT SECURITY SYSTEM AND METHOD - A method and system for document security are described. The method decrypts a key-map file located a composite document with embedded access control, decrypts a content part from the composite document with embedded access control, wherein the key-map file provides a key to access the content part, loads the content part in decrypted form into a document serialization maintained in a transient memory where the content part in decrypted form is maintained exclusively in the transient memory, and erases the content part in decrypted form upon termination of a program to access the decrypted content part from the document serialization. | 07-19-2012 |
| 20120185759 | SYSTEM AND METHOD FOR COLLABORATIVELY EDITING A COMPOSITE DOCUMENT - A method and system for collaboratively editing a composite document having a plurality of original document parts. For each of one or more original document parts, a non-editable version of the original document part may be stored. Edits to the original document part may be stored in a plurality of edit parts. Each of the plurality of edit parts may be editable by a single associated one of a plurality of users and may be non-editable by all other users of the plurality of users. The plurality of edit parts may be individually encrypted and the edit parts may be stored separately from the original document parts. | 07-19-2012 |
| 20120191983 | MANAGING INFORMATION IN A DOCUMENT SERIALIZATION - In a method for managing information comprising a reference name of an atomic unit listed in a document serialization, a new name for the atomic unit reference name is generated and occurrences of the atomic unit reference name in the document serialization are replaced with the new name for the atomic unit to conceal the atomic unit reference name. In addition, a map file containing a map file entry for each of a plurality of workflow participants is generated, in which each of the map file entries includes the new name and an access key to access the atomic unit. | 07-26-2012 |
| 20120260096 | METHOD AND SYSTEM FOR MONITORING A SECURE DOCUMENT - A method for enabling access to a secure document by a document service includes receiving the document, and an ordered sequence of signature verification keys that are to be selected in an orderly manner, from a document owner. Access is enabled to the document via an allocated access address. Uploading an uploaded document is enabled. A signature associated with the uploaded document is verified using a currently selected signature verification key from the ordered sequence. If verification fails, the uploaded document is rejected. If verification succeeds, the document accessible via the allocated access address is replaced with the uploaded document and a next signature verification key of the ordered sequence is selected to be the currently selected signature verification key. | 10-11-2012 |
| 20120290849 | MANAGING SEQUENTIAL ACCESS TO SECURE CONTENT USING AN ENCRYPTED WRAP - In a method for managing sequential access to secure content by a plurality of workflow participants, a key-map file for each of the participants is created. Each of the key-map files contains a subset of encryption and signature keys for the content. The key-map files are sorted in an order that is the reverse of a workflow order in which the workflow participants for which the key-map files were created are to access the secure content. An encrypted later wrap including a later key-map file for a later workflow participant along the workflow order and an encrypted first wrap including a prior key-map file for a prior workflow participant and the encrypted later wrap are created. In addition, the first wrap is incorporated into a document serialization for the content. | 11-15-2012 |
