User Identification in Wireless Networks

Christopher Swartz

9:00-11:00pm Friday, 27 February 2015, ITE 325B

Wireless communication using the 802.11 specifications is almost ubiquitous in daily life through an increasing variety of platforms. Traditional identification and authentication mechanisms employed for wireless communication commonly mimic physically connected devices and do not account for the broadcast nature of the medium. Both stationary and mobile devices that users interact with are regularly authenticated using a passphrase, pre-shared key, or an authentication server. Current research requires unfettered access to the user’s platform or information that is not normally volunteered.

We propose a mechanism to verify and validate the identity of 802.11 device users by applying machine learning algorithms. Existing work substantiates the application of machine learning for device identification using Commercial Off-The-Shelf (COTS) hardware and algorithms. This research seeks the refinement of and investigation of features relevant to identifying users. The approach is segmented into three main areas: a data ingest platform, processing, and classification.

Initial research proved that we can properly classify target devices with high precision, recall, and ROC using a sufficiently large real-world data set and a limited set of features. The primary contribution of this work is exploring the development of user identification through data observation. A combination of identifying new features, creating an online system, and limiting user interaction is the objective. We will create a prototype system and test the effectiveness and accuracy of it’s ability to properly identify users.

The aim in computer vision is to develop algorithms for computers to “see” the world as humans do. Central to this goal is understanding human behavior as an intelligent agent functioning in the visual world. For instance, in order for a robot to interact with us, it should understand our actions to produce the proper response. My work explores several directions towards computationally representing and understanding human actions.

In this talk, I will focus on detecting actions and judging their quality. First, I will describe simple grammars for modeling long-scale temporal structure in human actions. Real-world videos are typically composed of multiple action instances, where each instance is itself composed of sub-actions with variable durations and orderings. Our grammar models capture such hierarchical structure while admitting efficient, linear-time parsing algorithms for action detection. The second part of the talk will describe our algorithms for going beyond detecting actions to judging how well they are performed. Our learning-based framework provides feedback to the performer to improve the quality of his/her actions.

I am reclaiming my blackness. It’s been taken, twisted, and transformed into something I no longer recognized. It was deemed less than by the black kids, less than by the white kids, and left me navigating a space with an identity invalid.

My mom and I had a long “discussion” about the term Blackish. This began in reference to the popular TV show, but quickly went down a road that is still painful for me to revisit. In my mom’s opinion, she is black and I am blackish. I understood what she meant. I did not fit the stereotypical “black” mold. In fact, I fit the one she built for me. Predominantly white schools, a two parent household, sports, instruments, pets, private school, a car… the list goes on. These things were and continue to be my normal. Unfortunately, these things simultaneously made me “less than black”. How could that be?

My mom’s lived experiences are different. Her relationship with her dad is virtually nonexistent, she grew up in the inner city, her childhood was a low-income one. Is that what blackness is? Absentee dads? Poverty? The hood?

I’ve been ruminating on these thoughts this Black History Month. I’ve been thinking of my great-grandparents who didn’t establish themselves in a hood, but a neighborhood, with a car and a home they called their own. There were two parents and they worked hard to give their children a taste of middle-class life. They wore furs and diamonds, suits and church hats. They endured overt racism in ways I will never truly understand. Were they blackish too?

I am lost. I am exhausted at the thought of having to prove an identity that was handed to me. It covers every inch of my skin in a fantastic bronze hue. It dictates how strangers react to my face, my resume, my voice, my name. I am black. I am black first. I cannot be anything less.

“What do you say to the white kids when even the black kids say you’re not black enough for them?”

About:

The Baltimore City Mayoral Fellowship is a ten week, full-time experience that places individuals in a Mayoral office or agency.  Fellows are assigned to projects that focus on a myriad of public policy issues and challenges.  Fellows complete projects under the direction of senior level government officials and are provided immediate and direct feedback. 

In addition to gaining valuable practical experience and exposure to local government, Fellows present their findings to the Mayor and cabinet and complete a written final report documenting their research and solutions.  Fellows also enjoy outings and educational events where they network with peers and experience all that Baltimore has to offer.

This is an ideal program for current students and recent graduates with an interest in public service and local government.

This year’s Fellowship will run from June 1, 2015 to August 4, 2015.

Eligibility: 

Students who have completed the equivalent of their junior year of undergraduate coursework by the start date of the Fellowship will be considered.  Applicants need not be enrolled in a graduate level program to be considered.

Apply or Learn More: 

Attached please find a flyer outlining the program.  For further information or to apply, please visit our website: mayor.baltimorecity.gov/fellowship or contact me at bcmf@baltimorecity.gov.

We’re proud to announce that the Women’s Center at UMBC and Women of Color Coalition were recently awarded a $5,000 grant from the American Association of University Women (AAUW). The 2014–15 AAUW Campus Action Project (CAP) grants, sponsored by Pantene’s Shine Strong campaign, fund student led projects that fight stereotypes and biases.In addition to the AAUW CAP grant, we were also awarded a $500 community project grant from BreakingGround to help support this ambitious campaign. 

Our project, called “Telling Our Stories: I’m Not/I Am,” aims to 1) raise awareness and reject stereotypes about women of color, and 2) create space for women of color voices and counternarratives. Following a series of consciousness-raising discussions over the past year, many of our students saw the need to promote visibility and community-building among WoC in order to stand in solidarity against racist and sexist microaggressions. First-year student Jahia Knobloch vividly describes the harmful impact that stereotyping can have on women of color: 

Women of color are blessed with so many gifts: our beauty, compassion, ingenuity and grace are unparalleled. But too often our gifts are ignored, with ruthless stereotypes and myths being built around our existence which casting us into either unthreatening or highly exoticized and eroticized roles.

My first realizations about what it means to be a woman of color came, as so many realizations do, because of discrimination. Around the age of fourteen, I began receiving attention from boys and men. Many of these attentions were flattering; some were offensive and others downright menacing. But some of the most memorable comments I received were from non-POC boys and men. These comments were memorable only in their flabbergasting ignorance about what being attracted to a women of color apparently means in the minds of non-POC boys and men. Some examples: “I’ve never been with a Black girl before,” “You’re so pretty because you’re mixed—you’re lucky you only got the good features of being Black,” “I love your hair, it’s so dark,” and the jaw-dropping “I love the way your dark skin looks against my white skin.” Really dude?

I came to realize that as a woman of color, you are forced by proxy to represent the exotic “other”—a taste of a world in which non-POC men dare not venture into past a certain point. Even with our own races, we can be subjugated to lesser roles because of our status as women. Yet what those who wish to make us less-than do not see is that we can be the strongest of champions: not only for ourselves, but for our people and all those who are oppressed. We are a force to be reckoned with.

For me, dismantling stereotypes is so important because it gives us as WOC a chance to show that there is no “other.” We will not be your African, Asian, Latin, Native American or interracial vacation to the dark continent. We will not be a stop on your experimental college road trip for you to regale your friends about. We will not be a tourist attraction, an item on your bucket list or a milestone. We will only be us: beautiful, intelligent and independent. We will only be as strong as we have been made to be from centuries of oppression. We will continue to carry our status as WOC not as a burden, but as a gift. We will tell our stories. We will be heard.

By launching the project with the “I’m Not” poster campaign, we hope to disrupt the misguided assumption that racialized gender stereotyping is not a problem for our campus community. Click here to see the latest posters from the campaign! 

The second phase of the project consists of creative skill-building workshops which will culminate in a “Telling Our Stories: I Am” showcase. We intend to go beyond challenging the misrepresentation of women of color and actually create a platform dedicated to their authentic self-representation. Women of Color Coalition member-at-large Bree Best explains the importance of storytelling: 

Not only does telling your story tell people who you are but It give a different perspective of how to view things. These stories are needed and you, woman of color, have the pen in your hand ready to write it.

At the end of the showcase, I don’t want the conversation of women of color telling their stories to stay stagnant. I want this to continue because there are many “untold stories” in the woman of color sphere that need to be heard. These need to be heard so that they can help heal the multigenerational hurt that women of color have accrued. I believe if we tell our stories people will understand better how to heal or not hurt us through racial interactions.

The Telling Our Stories showcase will celebrate the creative self-expression of women of color and empower them to reclaim their own narratives. The showcase will be held on Wednesday, April 29th from 6-8pm in the Commons Sports Zone.
