With a tap on his smartphone, University of Maryland student Shiv Krishnamoorthy can instantly alert police as he walks through the dimly lit corners of the College Park campus — and share with them his precise location, plus live video and audio.

The app, which was developed by a university computer science professor and a team of students in conjunction with campus police, is the first of its kind in the small but growing field of smartphone apps for campus security.

M-Urgency will be available to Maryland students, faculty and staff early next month.

While the state university's flagship campus does not have a serious crime problem, Krishnamoorthy, a doctoral candidate who helped develop M-Urgency, said students are eager for smartphone applications that will help them feel safer on campus.

"This is something they're really looking forward to," Krishnamoorthy said.

Security-oriented apps are poised for growth, analysts said, particularly on college campuses, where a growing number of students are carrying the powerful, Internet-connected devices wherever they go.

After mass shootings at Columbine High School, Virginia Tech and other schools, campus security directors are seeing value in enabling their students to report urgent events in real time from their smartphones.

"Many, many police chiefs and directors of public safety have seen that their jobs change from being the head of a campus public safety entity to being an emergency manager on campus," said Paul Verrecchia, president of the International Association of Campus Law Enforcement Administrators and police chief of the College of Charleston in South Carolina.

Several companies are partnering with colleges and universities to provide such technology.

AT&T promotes a service called Rave Guardian that enables students to send information about themselves and their location to campus security.

The AT&T service also offers a precautionary timer: If a student sets the timer and doesn't arrive at his or her destination before the time elapses, the program immediately makes emergency notifications to friends, family or law enforcement.

AT&T charges college campuses licensing fees ranging from $10,000 for up to 5,000 full-time students to $50,000 for campuses that have more than 15,000 students, according to online promotional materials.

A Canadian startup called Guardly made its smartphone app available this year. It allows users to set up notification alerts by voice or text message to friends, family and authorities.

Its business model is similar to the home alarm industry, which typically makes money from monthly fees for alarm monitoring. The company is pursuing licensing deals with universities, according to chief executive Josh Sookman.

"It's a really big market opportunity," said Sookman, who said campuses can market their security tools to help retain students.

But security is a sensitive topic for image-conscious colleges, which some industry observers say are more inclined to promote apps that highlight campus amenities or engage alumni for fundraising purposes.

"There are other ways to make students feel safe," said Todd Marks, chief executive officer of Baltimore-based Mindgrub Inc., which makes mobile apps for colleges and other organizations.

Apps that help students use their phones to pay for food, order cabs, check bus schedules and transfer money can help make them safer by cutting down on the time they spend walking and waiting outside, he said.

The Johns Hopkins University has begun to make real-time updates on its shuttle buses available through NextBus.com. Hopkins officials hope the website, which can send text alerts on bus times, will help reduce the amount of time students wait on the streets for buses.
