**TrustScore** **- Driving Equitable, Inclusive and Secure Access to Services** EarthID is a decentralised identity platform that helps organisations prevent identity frauds, drive compliance and foster customer trust. Our vision is to drive social, financial, and digital inclusion. Our current platform offers a digital ID-wallet and verifiable credentials. As we strive for innovation, we aim to augment the EarthID by introducing a revolutionary TrustScore, a privacy-conscious, comprehensive evaluation of individuals' credibility and reliability. **Project Overview** EarthID's TrustScore revolutionises the assessment of trust and credibility in digital interactions. As access to essential services and financial opportunities increasingly relies on online identities, the absence of a unified, unbiased system to assess these identities leads to economic losses from fraud and social inequities. TrustScore is a decentralised, AI-powered numerical score derived from user-provided data, digital credentials from trusted issuers, and EarthID-powered interactions. It integrates multiple trust metrics into a single, privacy-conscious measure that offers a holistic view of an individual's credibility. **Expected Impacts** * **Societal Impact**: TrustScore will improve access to services like lending, housing, and employment for underserved populations, promoting social equity and reducing discrimination. Its global applicability allows individuals to carry their credit and social history across borders, potentially increasing access rates by 30%. This could benefit the 1.1 million unbanked adults in the UK and 1.4 billion globally. * **Economic Impact**: By reducing fraud and financial losses, TrustScore will boost economic growth and enhance market confidence. For the £450 billion global alternative lending market, TrustScore aims to reduce fraud by at least 20%, promoting economic stability. * **Environmental Impact**: Using Hedera's carbon-negative technology and decentralised storage, TrustScore reduces data redundancy, potentially cutting data centre energy consumption by 25%. This supports global climate goals and sustainable business practices. **Mitigating Potential Negative Impacts** Privacy concerns will be addressed using advanced privacy-preserving techniques like zero-knowledge proofs and purposeful consent, ensuring compliance with data privacy regulations such as GDPR. To avoid AI biases, diverse and representative training data will be used, with regular audits and feedback loops ensuring fairness and inclusivity. **Progress and Future Work** EarthID has developed a foundational framework for TrustScore, supported by its award-winning decentralised identity platform. EarthID has engaged key partners like HCL and TechMahindra to strengthen TrustScore's market adoption.

EarthID is a UK-based cybersecurity, fintech and Web3.0 focussed SME, led by a female co-founder/CEO and both co-founders of Indian ethnicity. The core project team comprises of Priya Guliani (Oxford/MIT-certified IT/blockchain/leadership professional) and Shiv Aggarwal (certified enterprise-architect, blockchain/SSI expert). EarthID's vision is to drive social, financial, and digital inclusion through the power of Self-Sovereign-Identity, aligned with 7/17 UN's Sustainable-Development-Goals. The academic-team, led by Professor Rajarajan, brings 20-years research and commercialisation expertise in data-privacy, cybersecurity, decentralised-identity, and blockchain. In 2020, the global cost of identity-fraud was £38.38B (Javelin-Strategy-Research,2021). In 2021, there were 226K cases of identity-fraud reported, an increase of 22%, which accounted for 63% of all fraud cases (National-Fraud-Database,2022). To prevent identity-thefts/frauds, financial institutions spend approximately £42.8M on customer-due-diligence processes. Major financial institutions spend up-to £446.25M protecting customer-data (Thomson-Reuters,2022). A cost-effective, fraud-proof solution is needed to reduce identity-thefts and associated financial, reputational, and emotional impact. From equality-diversity-inclusion standpoint, existing solutions rely on high-end smartphones, creating accessibility-barrier for people from lower socio-economic background. EarthID is developing Space-Wallet, a first-in-class cost-efficient, device-agnostic, fraud-proof, portable, reusable, user-centric, World-Wide-Web-Consortium compliant, cloud-based, decentralised-ID wallet that enables management of digital ID/credentials. Space-Wallet will enable organisations to issue, request and verify users' credentials in a fraud-proof and cost-efficient manner, while offering users data-ownership and privacy. Space-Wallet will be integrated with EarthID's multi award-winning platform, benefiting from its industry-leading capabilities. Space-Wallet will help organisations save up to 40% in expenses and 80% of their time through the prevention of identity-frauds (up to 90%), elimination of human-intervention, reuse of verified-data and paperless-processing. It will also remove the digital-divide by offering a device-agnostic solution. Space-Wallet will eliminate paper-based identity management processes, thereby reducing industry's carbon-footprint significantly. EarthID's Space-Wallet will help organisations prevent identity-frauds, drive compliance, optimise costs and foster sustainability, while empowering users with data ownership, privacy, and consent.
