Former Homeland Security chief speaks at ASU privacy-security forum

Michael Chertoff at ASU: Security and privacy are two sides of the same coin.
March 21, 2017

Michael Chertoff emphasized the importance of striking balance between privacy, security in an increasingly interconnected world

Cybersecurity infiltrations and terrorist attacks have filled the headlines in recent months. These issues pose a significant threat to U.S. national security and are likely to increase in the coming decade. Current efforts to protect against these threats can increase vulnerabilities and lead to invasions of privacy.

How much of our privacy must be sacrificed to achieve real security?

Former U.S. Secretary of Homeland Security Michael Chertoff and leaders from industry and academia met in an open forum Monday at Arizona State University to discuss this topic. The event, “Unlocking the Privacy-Security Debate,” was hosted jointly by the Sandra Day O’Connor College of Law and the Global Security Initiative at the Beus Center for Law and Society.

To Chertoff (pictured above), the goals of privacy and security are not mutually exclusive.

“I think security and privacy are not only better together, I think they have to be together,” he said. “They are two sides of the same coin.”

Cybersecurity breaches are in the news nearly every day, and the discussion tends to confuse these concepts by treating privacy and security as a zero-sum game, Chertoff said.

“All of this warrants a cool appraisal of where we are and where we need to be.”

Chertoff served as the second secretary of the U.S. Department of Homeland Security from 2005 to 2009. Previously, he worked as a federal judge on the U.S. Court of Appeals for the Third Circuit. Today, he is chairman and co-founder of the Chertoff Group, providing strategic counsel on global security solutions.

Chertoff took a measured view on government surveillance at the ASU forum, allowing that the intelligence community has a responsibility to disclose vulnerabilities that affect the general public, even if they may be exploited against our enemies. However, when it comes to metadata — the equivalent of telephone records — the secretary took a much more nuanced view.

“Surveillance should be viewed as a continuum,” he said Monday, making a distinction between the different phases of the intelligence process: collection, inspection, analysis and dissemination. According to Chertoff, often with metadata the significance is only evident in hindsight, and if that data has been collected and stored, it can be referenced to connect individual terrorists within networks.

Although when thinking about privacy we tend to picture government surveillance, “it’s amazing how much of our personal data is out there, not just from the government but the private sector — the volume is growing exponentially,” Chertoff said.

He also touched on other concerns that arise in our technologically enabled modern world. For instance, we may enjoy a discount from our health insurance provider when we share data from a fitness tracker. However, Chertoff warned that discounts for one person could mean penalties for another, and a future where we have “Big Mother” making sure we get enough exercise and eat our vegetables is far from unimaginable. This describes a violation of autonomy, our ability to make decisions freely, he said.

Privacy violations can be even more immediately dire when Wi-Fi-enabled pacemakers and self-driving cars are considered. These types of devices make up the Internet of Things, which could more aptly be called the “Internet of Everything,” according to Michelle Dennedy, vice president and chief privacy officer of tech conglomerate Cisco who also spoke at the event.

What can be done? How to do we solve this complex problem?

According to Ann Cavoukian, executive director of the Privacy and Big Data Institute at Ryerson University, we need to go back to square one. Privacy should be the default setting, embedded into the design. “Reject the notion that you are in the post-privacy era,” she insisted.

Jamie Winterton, director of Strategic Research Initiatives at GSI, echoed this solution, saying, “You don’t have to sacrifice your privacy to be secure.” Winterton suggested working with tech experts from the university as well as strategic partners to create technologies that preserve privacy, but not at the expense of security.

Ultimately, however, we are all responsible for our own individual privacy and security.

“It’s not a government function to protect you — you have to protect yourselves,” Chertoff said.

Researchers often look at how people experience water issues in their communities, but these studies are usually focused on a single region. One interdisciplinary group of researchers from Arizona State University, however, is taking a cross-cultural approach to look at water knowledge and management around the world.

In the most recent phase of the Global Ethnohydrology Study, this team interviewed people from communities in the United States, New Zealand, Fiji and Bolivia to see how perceptions of water risks and solutions varied depending on the community’s level of development and water scarcity.

“It can be a challenge to design cross-cultural research that produces meaningful results in a comparative context,” said Amber Wutich, co-author of the study and associate professor in the School of Human Evolution and Social Change. “This kind of work is important because it allows us to identify global trends in water problems and solutions.”

One of the unique factors about this project is its high amount of student involvement. Wutich said that mentoring is one of the most important ways the team informs others about their work.

“Through our graduate and undergraduate programs, we involve hundreds of students in the project in research design, data collection in international field sites and data analysis in our labs at ASU,” she said.

The results of the study found that people in wealthy and water-scarce areas were more concerned about water availability. Their solutions leaned toward collective action in creating policies. Meanwhile, people in poorer and relatively water-abundant regions had greater concern for water pollution, and suggested individual behavior changes as solutions.

“This research is important for tailoring water management strategies to the concerns and interests of local residents,” said Kelli Larson, lead author and associate professor in the School of Sustainability. The study lays the foundation for future comparative research, which will help policy and aid workers create solutions that are more likely to succeed for each individual region.

On World Water Day this March 22, Larson reflects on the 2017 theme, “wastewater,” which draws attention to the need to treat and reuse wastewater to protect the environment and make our water cycle more efficient.

“The implications of our research suggest that collective actions and policies in using wastewater may be more popular in developed areas, whereas individual practices and technologies may be more effective in less developed regions,” she said.
