The Digital Personal Data Protection (DPDP) Act 2023 creates a legal framework for the secured use of personal digital data to eliminate abuse. However, the Act’s provisions appear to have been drafted primarily with the e-commerce websites, personal data-based applications, and other digital customers in mind, not the healthcare community. Healthcare in the digital era requires communicating sensitive patient information over the web with clinicians for responsive advice and consultation. The consequences of such data-sharing involving medical personnel are not clear. Besides, the growth of digital health technologies requires patient data to be accessible anonymously and in de-identified form. Elimination of personal information alone does not guarantee de-identification. Also, to what specific detail one must describe the intended use of data for research and technology development is not articulated. Thus, the gray areas in the Act pose a challenge for the Indian medical ecosystem, which could incur penalties under the DPDP Act 2023.

This topic covers the development of a data-centric public health technology system, with insights from the NCD Portal for the National Non-communicable diseases program. The NCD Portal is used in 31 states and has more than 45 million people on treatment for hypertension and diabetes.
It explores the role of data in four key phases of the technology system: design, platform development, operations, and field adoption. In the design phase, data-driven insights, such as search patterns of frontline workers and medical officers optimize the user interface for speed and efficiency.
Platform development focuses on secure management and rule-based access control of data coming through APIs and data streams, transformed and cleaned, and going to the data warehouse for reporting needs.
Daily operations leverage Application Performance Monitoring (APM) tools and telemetry to identify and resolve performance issues proactively. Field adoption is enhanced through data analytics, guiding weekly reports for program review and feedback loops to prioritize feature development.
Embedding data-centricity throughout the system lifecycle supports large-scale, efficient and secure public health service delivery.

“Accurate data is the lifeblood of good policies and decision making”
As nations and organisations strive to solve social problems around the world, the lack of accurate data has often been cited as a primary reason why policies do not translate into effective on-ground solutions. The reality in urban informal settlements is no different. They manifest multidimensional deprivation, characterised by a lack of secure tenure, inaccessibility, and inadequate sanitation and health services which marginalises the slum dwellers. Governments and NGOs also find it extremely difficult to effectively target vulnerable communities due to the lack of reliable data. Data on slum settlements is crucial for the inclusion of these underserved communities in city level development plans.
Realising the dire need for safe and hygienic sanitation facilities and practices, Pratima started leveraging data and technology since the late 90s when she realised that data with the Urban Local Bodies was inconclusive and disjointed with the on-ground reality. This propelled the need for a data system that would provide unfailing results. A year of continuous efforts and iterations resulted in a well-tailored Geographical Information System (GIS). It catered to the needs of slum mapping, and spatial layout formation. It also helped to link the socio-economic surveys taken to individual dwellings/house structures that were mapped on GIS. Our granular spatial data harnesses the power of geo-visualisation for effective planning and monitoring of our Sanitation, Housing and Covid-relief projects.
The communities form the backbone of Shelter Associates’ data-driven approach, as they are involved in conducting survey, creating awareness and making sure the data sets are inclusive. This spatial data is then shared with the respective Urban Local Bodies for validation. Once the process is complete, the data is made public on our website while it is also linked to the ULB’s website making it freely available for all to use.
The co-created data helps immensely in bridging the information gap. SA gives slum-dwellers a voice by arming them with data about their community, empowering them to make decisions making them partners in the developmental process.

OpenCity.in is a leading urban data platform that democratises city data across India by enhancing transparency, fostering understanding and facilitating civic engagement. Alongside hosting an urban open data repository, we work to build a strong open data community.
OpenCity collaborative events or “jams” enable citizens to participate in finding solutions to urban issues; they serve as an effective tool for public problem solving. These events bring together participants from diverse and multidisciplinary backgrounds to open up data, analyse it, and derive actionable insights. From water management to urban mobility, our crowdsourcing projects, datajams, hackathons, and solution jams, have become instrumental in breaking down data silos, revealing patterns, and constructing “what-if” scenarios to propose innovative solutions to pressing public issues.
Through these initiatives, OpenCity provides opportunities for the public to engage with urban issues, which can lead to actionable insights and potential solutions. Our approach brings the power of collective intelligence to drive civic action for better cities.

Digital interfaces and communications have become critical for access to information, entertainment, economic opportunities and even essential services such as healthcare. Speech is the most natural form of communication, and most Indians are not digital natives comfortable with typing or English. We need spoken language interfaces that work for all variations and dialects. But such data barely exists. IISc-ARTPARK’s umbrella of open-source speech data initiatives are capturing the true diversity of India’s spoken languages to propel language AI technologies and content for an inclusive digital India, in collaboration with Bhashini, MEITY.

As organisations increasingly rely on data-driven insights to fuel innovation, collaboration and decision-making, the need to process sensitive data, such as data containing PII, confidential business information etc., securely has become more critical than ever. Further, the organisations are increasingly tasked with balancing the utility of data with the need to protect individual privacy. Traditional methods of data protection and data anonymization often fall short, especially when computations are performed on datasets containing sensitive information. Privacy Enhancing Technologies (PETs) offer a transformative technological approach, enabling secure computation and further, enabling balancing privacy and utility while working with the underlying data.
This talk will explore the integration of PETs into computational processes involving sensitive and private data, and securing data in its different states: at rest, in transit, in-use and post-use. We will discuss the role of foundational PETs such as Confidential computation with hardware based Secure Enclaves, secure multi-party computation, homomorphic encryption, and federated learning, examining how these technologies protect data across its lifecycle, ensuring that sensitive information remains secure whether it is stored, transmitted, actively processed or released after undergoing some aggregation transformation. We will also discuss implementation, performance and deployment issues concerning PETs. We will present different use cases where secure computation is paramount and PETs become a key enabler. Overall the talk will provide a good overview on how PETs can be effectively incorporated into computational workflows to enhance data privacy across all stages and provide some actionable insights on leveraging PETs to securely manage and compute sensitive data in your organization.
