Different Approaches To Blurring Digital Images And Their Effect On Facial Detection, Erich-Matthew Pulfer
Different Approaches To Blurring Digital Images And Their Effect On Facial Detection, Erich-Matthew Pulfer
Computer Science and Computer Engineering Undergraduate Honors Theses
The purpose of this thesis is to analyze the usage of multiple image blurring techniques and determine their effectiveness in combatting facial detection algorithms. This type of analysis is anticipated to reveal potential flaws in the privacy expected from blurring images or, rather, portions of images. Three different blurring algorithms were designed and implemented: a box blurring method, a Gaussian blurring method, and a differential privacy-based pixilation method. Datasets of images were collected from multiple sources, including the AT&T Database of Faces. Each of these three methods were implemented via their own original method, but, because of how common they …
Exploring Photo Privacy Protection On Smartphones, David Darling
Exploring Photo Privacy Protection On Smartphones, David Darling
Computer Science and Computer Engineering Undergraduate Honors Theses
The proliferation of modern smartphone camera use in the past decade has resulted in unprecedented numbers of personal photos being taken and stored on popular devices. However, it has also caused privacy concerns. These photos sometimes contain potentially harmful information if they were to be leaked such as the personally identifiable information found on ID cards or in legal documents. With current security measures on iOS and Android phones, it is possible for 3rd party apps downloaded from official app stores or other locations to access the photo libraries on these devices without user knowledge or consent. Additionally, the prevalence …
An Innovative Approach Towards Applying Chaum Mixing To Sms, Matthew Patrick Rothmeyer
An Innovative Approach Towards Applying Chaum Mixing To Sms, Matthew Patrick Rothmeyer
Graduate Theses and Dissertations
Currently there are few user-friendly applications for anonymous communication across multiple platforms, leaving data that is often both personal and private vulnerable to malicious activity. Mobile devices such as smartphones are prime candidates for such an application as they are pervasive and have standardized communication protocols. Through the application of mixing techniques, these devices can provide anonymity for groups of individuals numbering 30 to 40 members. In this work, a Chaum mix inspired, smartphone based network that uses the Short Message Service (SMS) is described first in theory and then in implementation. This system leverages both techniques used by current …
