«Our Future: Through a Data-Driven Lens» by Catalina Valentino

07/02/2024 South Summit

The future of our towns, cities and communities relies heavily on tech. How can we create
smarter cities, which provide ample opportunities and give back to those who inhabit it?

The answer lies in data.

Data is like the compass guiding us through the complexities of things like urban
development, smart cities and communities. It helps us make informed decisions and
measure our impact. By embracing a data-driven approach, we can transform our cities into
dynamic, inclusive spaces that cater to the diverse needs of their inhabitants.

But it’s not just thinking about data after a place has been built, but thinking ahead. For
instance, before a place is built – as it’s being planned, during its construction, and then
after, whilst it’s in use by the communities who inhabit it.

Using Data to
Build Smart Cities

One of the greatest advantages of using data in urban planning and when creating smart
cities is the ability to understand how people move, interact, and live within their
communities. By analysing various datasets, such as population demographics and
transportation patterns, city planners can identify areas for improvement and allocate
resources more efficiently.

But it’s not just in the data analysis, it’s about integrating different data sets and integrations
into existing capabilities to enrich the data and understanding and enable faster performance
and better decision-making. For instance, real-time traffic data can help us optimise
transportation routes, reducing congestion and pollution.

But it’s not just about efficiency; it’s also about fairness.

Data allows us to see where inequalities exist and take action to address them.

By understanding the unique challenges facing different neighbourhoods, policymakers can
tailor policies and services to ensure that everyone has access to essential resources like
education, healthcare, and job opportunities.

And, one step further, data can help us pinpoint areas with higher crime rates or
environmental risks, allowing us to implement targeted interventions to improve safety and
quality of life for all residents.

Yet, as we embrace data-driven solutions, we must also consider the importance of ethical
considerations, and challenges such as privacy, security, and bias cannot be ignored.

We must prioritise finding the strongest solutions for the protection of personal data,
safeguard against potential breaches, and ensure that algorithms are fair and transparent.

Data Benefits
For All

But taking one step further, we must ensure we make the benefits of data-driven
development accessible to everyone. This means bridging the digital divide and ensuring
that all members of society have the tools and skills to participate in the digital economy.
These benefits could include improved access to services, better infrastructure, enhanced
quality of life, economic opportunities, and more. The idea is that everyone in society should
have the opportunity to enjoy these benefits, regardless of their background or
circumstances, and that only by fostering inclusivity and equity can we truly create cities that
work for everyone.

Innovation and
Data Sharing

Now, introducing innovation can often be seen as scary. But fear not, innovation in data
sharing between organisations holds tremendous potential for driving collaboration, fostering
innovation, and addressing complex societal challenges. And ensuring the privacy and
security of sensitive information is essential in this process.

One approach to achieving this balance is through data anonymization, a technique that
removes personally identifiable information from datasets while preserving their utility for
analysis and research.

Data anonymization involves transforming raw data in a way that individuals cannot be
re-identified. Techniques such as randomisation, aggregation, and noise addition can be
applied to mask sensitive information while still maintaining the overall structure and patterns
within the data. By anonymising data before sharing it with external parties, organisations
can mitigate privacy risks and comply with data protection regulations.

Another safe practice in data sharing is the use of secure data sharing platforms and
protocols. These platforms employ encryption and access controls to ensure that only
authorised parties can access and use the shared data. Additionally, organisations can
implement data usage agreements and contracts that outline the terms and conditions for
accessing and processing shared data, including restrictions on data re-identification and
unauthorised use.

Getting Down Into The Details: Homomorphic Encryption vs Federated Learning

And if we want to get real ‘techy’, emerging technologies such as ‘homomorphic encryption’
and ‘federated learning’ offer innovative approaches to data sharing while preserving privacy.

Homomorphic encryption allows computations to be performed on encrypted data without
decrypting it, enabling organisations to collaborate on data analysis without exposing
sensitive information.

Federated learning, on the other hand, enables model training across decentralised data
sources without sharing raw data, thereby preserving privacy and confidentiality.

In the end, the path to a brighter future for our cities is paved with data. By leveraging the
power of information, we can build smarter, more sustainable, and more equitable
communities. But it’s not just about the data; it’s about using it to make a positive difference
in people’s lives. That’s the real promise of our data-driven future.
