Ethics is a crucial aspect of life, and similar to its application in our daily lives, ethical considerations should also apply in the tech world. 

Disruptive technologies such as AI, ML, Internet of Things (IoT), computer vision, etc., require all sorts of data to operate. This data often includes biometric data, such as facial images and voice recordings. Collecting and managing such data requires various ethical and legal considerations, which, if disregarded, can lead to expensive lawsuits.

See data collection ethics and legal practices that can be considered while sourcing/gathering data to develop and deploy data-hungry AI/ML solutions.

How to achieve data collection ethics? (Best practices)

Extensive research has been done on data collection ethics and how to achieve it; however, there is no golden door to the land of absoluteness. Ethics is more of a process and a culture that needs to be adopted by all contributors (data collectors, developers, decision-makers, sales, marketing, executives, etc.) in developing and implementing an AI/ML solution. 

Specifically for data collectors, this section highlights some best practices they can follow:

Ethics training

Providing sufficient training about data collection ethics can be beneficial in promoting and adopting the culture. A best practice to ensure the instructions are heeded is using an ethics checklist that the staff should tick off whenever they collect data. 

You can also check our data-driven list of data collection/harvesting services to find the option that best suits your business needs. 

Obtaining consent is one of the most critical parts of data collection ethics. This is part of the agreement between the data owner and the collector, and should be done. Before the data is collected, for instance, if a smart home device gathers voice data from its user, there should be a notification while setting up the app, giving the user the option to provide consent.

Clarity and understanding

This means that when collectors require user consent, their request should be clearly stated in easily understandable words. The data collectors should ensure that the user fully understands what he/she is permitting.

Trust and consistency

This means ethical and security practices while collecting data should be consistent to build trust in the data provider. For instance, if there are 500 data providers, then all 500 of them should be subjected to equal ethical considerations.

Awareness and Transparency

The data collection process should be transparent. The data provider should know what data is being collected, who will have access to it, and how it will be used. 

Additionally, data providers should have control over how their data is used. For instance, if the data provider wants to stop using and sharing data in the future, he/she should be able to opt out easily.

Risk consideration

Another critical point to consider is that the risk of problems occurring in the future can never be eliminated. Therefore, the data collection must assess the risk of such unforeseen events and prepare a mitigation plan. Additionally, the data collector should communicate this risk to the data provider.

History of Major Data Collection Lawsuits (Case studies)

Unethical facial recognition data collection

The Washington Post reported that the U.S. immigration and Customs Enforcement authority unconstitutionally collected facial image data to track the activities of immigrants.

Voice data collection by smart home devices

Similarly, brands that offer smart home devices have also been under scrutiny for unethically collecting voice (biometric) data from their users. 

For instance, Alexa was under a lawsuit for collecting user voice data without consent. A collaborative study by researchers from the University of Washington and three other institutions found this, leading to the lawsuit.
