Each week J. J. Green will look at technologies role in national security focusing on such things as GPS OCX ,Information Security
Identity Management, Immigration Control etc. What agencies are having success and what challenges does the future hold.
GPS-Power Transmission
Efficient power transmission and distribution requires power companies and utilities to rely on time and frequency. Repeated power blackouts have demonstrated to power companies the need for improved time synchronization throughout the power grid. Analysis of these blackouts have led many companies to place GPS-based time synchronization devices in power plants and substations. By analyzing the precise timing of an electrical anomaly as it propagates through a grid, engineers can trace back the exact location of a power line break.
Information Security vs Cyber Threats
04-03-09Is it possible to defend against every cyber threat. Yes, but experts say it would be costly and limit connectivity, and productivity for companies who rely on the internet. These same experts advocate developing new infrastructure with security features built-in to get the job done. And for older systems they should be fortified to protect against hackers from inside the company and out.
GPS-Time Stamps
04-03-09GPS. It's way more than mapquest. Companies worldwide use GPS to time-stamp business transactions, providing a consistent and accurate way to maintain records and ensure their traceability. Investment banks use GPS to synchronize their network computers located around the world. Tracking, updating, and managing multiple transactions made by a global network of customers, requires accurate timing information available through GPS.
Biometrics Paves the Way
04-03-09How do you strike the balance between safe travel and security? Biometric appears to be the way. Biometrics involves technologies that measure and analyze human body characteristics, such as fingerprints, eye retinas and irises, voice patterns, facial patterns and hand measurements, for authentication purposes. Use of bio metrics was treated with a great deal of skepticism in then past, but now people hardly notice a fingerprint or eye scan while traveling.
What GPS Means for Wireless
03-30-09Wireless telephone and data networks use GPS time to keep all of their base stations in perfect synchronization.
Why? This allows mobile handsets to share limited radio spectrum more efficiently.
By the same token, digital broadcast radio services use GPS time to ensure that the bits from all radio stations arrive at receivers in lockstep.
This allows listeners to tune between stations with a minimum of delay.
Cyber Insecurity
03-23-09Earlier this year a file containing the blueprints and avionics package for Marine One was found on a computer in Iran. It looks like the files were compromised after a government contractor used a peer-to-peer file sharing program to store them. Experts have noticed an increase in virus and denial of service attacks on sites such as Facebook, and Twitter. Attacks in the third quarter or last year shot up more than 15%.
