Improving Password Security and Usability with Data-Driven Approaches

Blase Ur, CMU

12:30pm Friday, 11 March 2016, ITE325b

Users often must make security and privacy decisions, yet are rarely equipped to do so. In my research, I aim to understand both computer systems and the humans who use them. Armed with this understanding, I design and build tools that help users protect their security and privacy.

In this talk, I will describe how I applied this research approach to password security and usability. As understanding what makes a password good or bad is crucial to this process, I will first discuss our work on metrics for password strength. These metrics commonly involve modeling password cracking, which we found often vastly underestimates passwords’ vulnerability to cracking in the real world. We instead propose combining a series of carefully configured approaches, which we found to conservatively model real-world experts. We used these insights to implement a Password Guessability Service, which is already used by nearly two dozen research groups. I will then discuss our work on another key step to helping users create better passwords: understanding why humans create the passwords they do. I will focus on the impact of password-strength meters and users’ perceptions of password security. By combining better metrics with an understanding of users, I show how we can design tools that guide users toward better passwords.

Blase Ur is a Ph.D. candidate at Carnegie Mellon University’s School of Computer Science, where he is advised by Lorrie Cranor. His research interests lie at the intersection of security, privacy, and human-computer interaction (HCI). In addition to his work on password security, he has studied numerous aspects of online privacy and the Internet of Things (IoT). Previously, he obtained his A.B. in Computer Science from Harvard University. He is the recipient of an NDSEG fellowship, a Fulbright scholarship, a Yahoo Key Scientific Challenges Award, the best paper award at UbiComp 2014, and honorable mentions for best paper at both CHI 2012 and CHI 2016.

St. Patrick’s Day is celebrated on March 17, the saint’s religious feast day and the anniversary of his death in the fifth century. The Irish have observed this day as a religious holiday for over 1,000 years. On St. Patrick’s Day, which falls during the Christian season of Lent, Irish families would traditionally attend church in the morning and celebrate in the afternoon. Lenten prohibitions against the consumption of meat were waived and people would dance, drink and feast–on the traditional meal of Irish bacon and cabbage.

ST. PATRICK AND THE FIRST ST. PATRICK’S DAY PARADE

Saint Patrick, who lived during the fifth century, is the patron saint and national apostle of Ireland. Born in Roman Britain, he was kidnapped and brought to Ireland as a slave at the age of 16. He later escaped, but returned to Ireland and was credited with bringing Christianity to its people. In the centuries following Patrick’s death (believed to have been on March 17, 461), the mythology surrounding his life became ever more ingrained in the Irish culture: Perhaps the most well known legend is that he explained the Holy Trinity (Father, Son and Holy Spirit) using the three leaves of a native Irish clover, the shamrock.

More than 100 St. Patrick's Day parades are held across the United States; New York City and Boston are home to the largest celebrations.

Since around the ninth or 10th century, people in Ireland have been observing the Roman Catholic feast day of St. Patrick on March 17. Interestingly, however, the first parade held to honor St. Patrick’s Day took place not in Ireland but in the United States. On March 17, 1762, Irish soldiers serving in the English military marched through New York City. Along with their music, the parade helped the soldiers reconnect with their Irish roots, as well as with fellow Irishmen serving in the English army.

ST. PATRICK’S DAY, NO IRISH NEED APPLY AND THE “GREEN MACHINE”

Up until the mid-19th century, most Irish immigrants in America were members of the Protestant middle class. When the Great Potato Famine hit Ireland in 1845, close to 1 million poor and uneducated Irish Catholics began pouring into America to escape starvation. Despised for their alien religious beliefs and unfamiliar accents by the American Protestant majority, the immigrants had trouble finding even menial jobs. When Irish Americans in the country’s cities took to the streets on St. Patrick’s Day to celebrate their heritage, newspapers portrayed them in cartoons as drunk, violent monkeys.

The American Irish soon began to realize, however, that their large and growing numbers endowed them with a political power that had yet to be exploited. They started to organize, and their voting block, known as the “green machine,” became an important swing vote for political hopefuls. Suddenly, annual St. Patrick’s Day parades became a show of strength for Irish Americans, as well as a must-attend event for a slew of political candidates. In 1948, President Harry S. Truman attended New York City‘s St. Patrick’s Day parade, a proud moment for the many Irish Americans whose ancestors had to fight stereotypes and racial prejudice to find acceptance in the New World.

THE CHICAGO RIVER ON ST. PATRICK’S DAY

As Irish immigrants spread out over the United States, other cities developed their own traditions. One of these is Chicago’s annual dyeing of the Chicago River green. The practice started in 1962, when city pollution-control workers used dyes to trace illegal sewage discharges and realized that the green dye might provide a unique way to celebrate the holiday. That year, they released 100 pounds of green vegetable dye into the river–enough to keep it green for a week! Today, in order to minimize environmental damage, only 40 pounds of dye are used, and the river turns green for only several hours.

Although Chicago historians claim their city’s idea for a river of green was original, some natives of Savannah, Georgia (whose St. Patrick’s Day parade, the oldest in the nation, dates back to 1813) believe the idea originated in their town. They point out that, in 1961, a hotel restaurant manager named Tom Woolley convinced city officials to dye Savannah’s river green. The experiment didn’t exactly work as planned, and the water only took on a slight greenish hue. Savannah never attempted to dye its river again, but Woolley maintains (though others refute the claim) that he personally suggested the idea to Chicago’s Mayor Richard J. Daley.

ST. PATRICK’S DAY AROUND THE WORLD

Today, people of all backgrounds celebrate St. Patrick’s Day, especially throughout the United States, Canada and Australia. Although North America is home to the largest productions, St. Patrick’s Day is celebrated in many other locations far from Ireland, including Japan, Singapore and Russia.

In modern-day Ireland, St. Patrick’s Day was traditionally been a religious occasion. In fact, up until the 1970s, Irish laws mandated that pubs be closed on March 17. Beginning in 1995, however, the Irish government began a national campaign to use interest in St. Patrick’s Day to drive tourism and showcase Ireland and Irish culture to the rest of the world. Today, approximately 1 million people annually take part in Ireland‘s St. Patrick’s Festival in Dublin, a multi-day celebration featuring parades, concerts, outdoor theater productions and fireworks shows.
