USC Password Study (ACSAC Demo Page)
You are invited to participate in a research study conducted by Professor Jelena Mirkovic
and Simon Woo, at the University of Southern California. This webpage explains the structure and purpose of this study. You should ask questions about anything that is unclear to you (see Contact Information below).
This study examines the use of memorable experiences from a person's life for creation of unique, easy-to-remember, hard-to-guess passwords. You must be aged 18 or older to participate. Your participation is voluntary.
In the study you will be asked to create a life-experience password (LEP). You will then be asked to authenticate by answering questions generated from your LEP.
You will be asked to input information about a personal experience of your choice into our system, either in your own words or by answering questions posed by the system.
We will use your input to extract facts about time, locations, people and activities in your experience. We will transform these
facts into verification question/answer pairs. We will use the verification questions to prompt
you during verification. The verification answers become your LEP.
At the end of the creation or any time in the future you can proceed to the authentication step and try to authenticate with your LEP.
Potential Risks and Discomforts
There is minimal risk to you from feeling discomfort if you choose to use an unpleasant memory to create a
LEP. You are asked not to choose any events which involve illegal behavior or information that could have negative consequences for you, for example, cheating, theft, etc.
Alternatives to Participation
There are no adverse effects to you if you choose not to participate in this study or if you decide to withdraw at any point. If you are USC student, your grades will not be affected, whether or not you participate in this study.
The University of Southern California's Human Subjects Protection Program (HSPP)
reviews and monitors research studies to protect the rights and welfare of research subjects.
We will protect your privacy in the following way:
The data stored on our server will remain there indefinitely and may be used by us in future studies.
- 1.We will not ask you for any identifying information, such as name, email, etc. The system will assign you a random identifier for the study.
- All your input will be stored and examined by our research staff. The input will be stored indefinitely.
- Your verification questions (but not answers) may be viewed by other participants in the study so we can measure how easy it is for others to guess LEPs.
You have the right at any time to request this data to be removed from our server
by sending email to the Principal Investigator at email@example.com and providing the identifier that was assigned to you for this study.
When the results of the research are published or discussed in conferences, no identifiable information will be used.
We will list our publications and publications of any researchers who use this data at our project page:
Potential Benefits to Participants and/or to Society
While you may not directly benefit from your participation in this study, your input will help us design more secure, more memorable passwords.
Participation and Withdrawal
Your participation is voluntary. Your refusal to participate will involve no penalty or loss of benefits to which you are otherwise entitled. You may withdraw your participation at any time and discontinue without penalty. You are not waiving any legal claims, rights or remedies because of your participation in this research study.
