The Department of Homeland Security has been forced to release a list of keywords and phrases it uses to monitor social networking sites and online media for signs of terrorist or other threats against the U.S.

The intriguing the list includes obvious choices such as 'attack', 'Al Qaeda', 'terrorism' and 'dirty bomb' alongside dozens of seemingly innocent words like 'pork', 'cloud', 'team' and 'Mexico'.

Released under a freedom of information request, the information sheds new light on how government analysts are instructed to patrol the internet searching for domestic and external threats. The words are included in the department's 2011 'Analyst's Desktop Binder' used by workers at their National Operations Center which instructs workers to identify 'media reports that reflect adversely on DHS and response activities'.

Department chiefs were forced to release the manual following a House hearing over documents obtained through a Freedom of Information Act lawsuit which revealed how analysts monitor social networks and media organisations for comments that 'reflect adversely' on the government.

A senior Homeland Security official told the Huffington Post that the manual 'is a starting point, not the endgame' in maintaining situational awareness of natural and man-made threats and denied that the government was monitoring signs of dissent. However the agency admitted that the language used was vague and in need of updating. Spokesman Matthew Chandler told website: 'To ensure clarity, as part of ... routine compliance review, DHS will review the language contained in all materials to clearly and accurately convey the parameters and intention of the program.'

Northside Independent School District plans to track students next year on two of its campuses using technology implanted in their student identification cards in a trial that could eventually include all 112 of its schools and all of its nearly 100,000 students.

District officials said the Radio Frequency Identification System (RFID) tags would improve safety by allowing them to locate students - and count them more accurately at the beginning of the school day to help offset cuts in state funding, which is partly based on attendance.

Northside, the largest school district in Bexar County, plans to modify the ID cards next year for all students attending John Jay High School, Anson Jones Middle School and all special education students who ride district buses. That will add up to about 6,290 students.

"We want to harness the power of (the) technology to make schools safer, know where our students are all the time in a school, and increase revenues," district spokesman Pascual Gonzalez said. "Parents expect that we always know where their children are, and this technology will help us do that."

Chip readers on campuses and on school buses can detect a student's location but can't track them once they leave school property. Only authorized administrative officials will have access to the information, Gonzalez said.
"This way we can see if a student is at the nurse's office or elsewhere on campus, when they normally are counted for attendance in first period," he said.

The district plans to spend $525,065 to implement the pilot program and $136,005 per year to run it, but it will more than pay for itself, predicted Steve Bassett, Northside's assistant superintendent for budget and finance. If successful, Northside would get $1.7 million next year from both higher attendance and Medicaid reimbursements for busing special education students, he said.
But the payoff could be a lot bigger if the program goes district wide, Bassett said.

In Tuesday's board debate, trustee M'Lissa M. Chumbley said she worried that parents might feel the technology violated their children's privacy rights. She didn't want administrators tracking teachers' every move if they end up outfitted with the tags, she added. "I think this is overstepping our bounds and is inappropriate," Chumbley said. "I'm honestly uncomfortable about this."
