Ethical Guidelines

University of Illinois trained engineers are the best and most highly sought in the world. Our graduates are superbly trained, highly competent, and creative. This, however, is not enough. Our engineers must also be trusted to conduct themselves according to the highest ethical standards. All teams must address ethical considerations in their projects. This requirement has two parts.

First, there is a stringent Code of Ethics published by professional societies, such as IEEE and ACM. The power of these Codes of Ethics is to provide guidance to engineers in decision making and to lend the weight of the collective community of engineers to individuals taking a stand on ethical issues. Thus the Code of Ethics both limits the professional engineer and empowers the professional engineer to stand firm on fundamental ethical bedrock. All teams must read the IEEE code and ACM code and comment on any sections of the code that bear directly on the project.

Second, we expect our students to have personal standards of conduct consistent with the IEEE and ACM Codes of Ethics, but also beyond it. That is, there are areas of ethics not addressed by these Codes that the engineer may consider in taking on projects or jobs or making other professional decisions. These are personal standards and choices. In the context of the class, there are no right or wrong answers here. Our students simply need to demonstrate that they are thinking deeply about their own decisions and the consequences of those decisions. We encourage our students to consider the wider impact of their projects and address any concerns raised by potential uses of the project. Students should ask themselves, "Would I be comfortable having my name widely attached to this project? Do I want to live in a society where this product is available or widely used? Would I be proud of a career dominated by the decision making demonstrated here?" Remember that UIUC engineers have a long history of inventions that really has changed the world.

If the students feel that these Codes of Ethics does not directly bear on their project and that there are no other reasonable concerns, they should not invent issues where there are none. Students will still be expected to be familiar with the IEEE Code of Ethics and ACM Code of Ethics.

Electronic Replacement for COVID-19 Building Monitors @ UIUC

Problem Statement:

Students who volunteer to monitor buildings at UIUC are at increased risk of contracting COVID-19 itself, and passing it on to others before they are aware of the infection. Due to this, I propose a project that would create a technological solution to this issue using physical 2-factor authentication through the “airlock” style doorways we have at ECEB and across campus.

Solution Overview:

As we do not have access to the backend of the Safer Illinois application, or the ability to use campus buildings as a workspace for our project, we will be designing a proof of concept 2FA system for UIUC building access. Our solution would be composed of two main subsystems, one that allows initial entry into the “airlock” portion of the building using a scannable QR code, and the other that detects the number of people that entered the space, to determine whether or not the user will be granted access to the interior of the building.

Solution Components:

Subsystem #1: Initial Detection of Building Access

- QR/barcode scanner capable of reading the code presented by the user, that tells the system whether that person has been granted or denied building access. (An example of this type of sensor: (https://www.amazon.com/Barcode-Reading-Scanner-Electronic-Connector/dp/B082B8SVB2/ref=sr_1_11?dchild=1&keywords=gm65+scanner&qid=1595651995&sr=8-11)

- QR code generator using C++/Python to support the QR code scanner.

- Microcontroller to receive the information from the QR code reader and decode the information, then decide whether to unlock the door, or keep it shut. (The microcontroller would also need an internal timer, as we plan on encoding a lifespan into the QR code, therefore making them unusable after 4 days).

- LED Light to indicate to the user whether or not access was granted.

- Electronic locking mechanism to open both sets of doors.

Subsystem #2: Airlock Authentication of a Single User

- 2 aligned sensors ( one tx and other is rx) on the bottom of the door that counts the number of people crossing a certain line. (possibly considering two sets of these, so the person could not jump over, or move under the sensors. Most likely having the second set around the middle of the door frame.

- Microcontroller to decode the information provided by the door sensors, and then determine the number of people who have entered the space. Based on this information we can either grant or deny access to the interior building.

- LED Light to indicate to the user if they have been granted access.

- Possibly a speaker at this stage as well, to tell the user the reason they have not been granted access, and letting them know the

incident has been reported if they attempted to let someone into the building.

Criterion of Success:

- Our system generates valid QR codes that can be read by our scanner, and the data encoded such as lifespan of the code and building access is transmitted to the microcontroller.

- Our 2FA detection of multiple entries into the space works across a wide range of users. This includes users bound to wheelchairs, and a wide range of heights and body sizes.
