Patent Issued for Data Synchronization and Integrity for Intermittently Connected Sensors

May 27, 2014



By a News Reporter-Staff News Editor at Information Technology Newsweekly -- From Alexandria, Virginia, VerticalNews journalists report that a patent by the inventors Ayyagari, Arun (Seattle, WA); Ung, Kevin Y. (Bellevue, WA); Matsen, Marc R. (Seattle, WA); Johnson, Karl L. (Seattle, WA); Blackwell, David B. (Seattle, WA); Coop, William P. (Kent, WA), filed on May 30, 2007, was published online on May 13, 2014.

The patent's assignee for patent number 8723645 is The Boeing Company (Chicago, IL).

News editors obtained the following quote from the background information supplied by the inventors: "The present invention relates to data synchronization and integrity and more particularly to a system and method for data synchronization and integrity for intermittently connected sensors.

"Radio Frequency Identification (RFID) is being implemented in various new applications. One proposed application is deployment on-board aircraft and within product supply chains including manufacturing. Such deployment will require the integration of critical business processes such as industrial tracking and inventory/asset management. This evinces the need for security and access control applications when using RFID based sensor networks to ensure that the deployed systems adequately protect competition sensitive infrastructure and information associated with the critical business processes. Securing RFID tag data is essential to thwart the entry of counterfeit parts into the supply chain of the original equipment manufacturers (OEM) via early detection. While this is important to industry at large, it is crucial to aerospace, pharmaceutical, and automotive industries. Securing end-to-end data flow to ensure that critical information cannot be queried nor viewed by unauthorized entities is important and requires access control."

As a supplement to the background information on this patent, VerticalNews correspondents also obtained the inventors' summary information for this patent: "In accordance with an embodiment of the present invention, a system for data synchronization of intermittently connected sensors may include an application to ensure the integrity of the data retrieved or posted between a front-end RFID system and a backend information system. The system may also include a data schema for user data on an RFID tag that minimizes an amount of data that may need to be read from the tag. The system may also include a context and event manager functionality being maintained on an RFID reader to ensure more effective contextual RFID tag read/write operation. A data store-forward capability may be provided within the RFID reader and an event manager to ensure continued operation when disconnected from the backend information management system and to also ensure that there is no overall loss of data during the disconnection. A data locking mechanism and synchronization mechanism may be provided between the front-end application and the backend IM system to ensure proper operation of backend applications and decision support systems. The system may further include a cryptographic hash associated with each RFID tag for write operations to ensure effective data validation for data read from the tag and that may be stored on the secure backend information management system.

"In accordance with another embodiment of the present invention, a system for data synchronization of intermittently connected sensors may include an RFID system and an information management system. The system may also include an application to insure integrity of data retrieved or posted between the RFID system and the information management system.

"In accordance with another embodiment of the present invention, a method for data synchronization of intermittently connected sensors may include providing a data schema to minimize an amount of data to be read from an RFID tag. The method may also include maintaining context and event manager functionality on an RFID reader to facilitate contextual RFID tag read/write operation.

"In accordance with another embodiment of the present invention, a system for maintaining an aircraft may include an RFID system for reading and writing information on an RFID tag associated with a component of the aircraft. The system may also include an information management system and an application to insure integrity of data retrieved or posted between the RFID system and the information management system.

"In accordance with another embodiment of the present invention, a method for maintaining an aircraft may include associating an RFID tag with an aircraft component. The method may also include providing security for data on the RFID tag.

"Other aspects and features of the present invention, as defined solely by the claims, will become apparent to those ordinarily skilled in the art upon review of the following non-limited detailed description of the invention in conjunction with the accompanying figures."
