  • DoT develops Facial Recognition Tool ‘ASTR’

    astr

    Central Idea: The Department of Telecommunications (DoT) has developed an artificial-intelligence-based facial recognition tool called Artificial Intelligence and Facial Recognition powered Solution for Telecom SIM Subscriber Verification (ASTR).

    What is ASTR?

    • ASTR is designed to check subscriber databases of telecom operators to identify multiple connections associated with the same person.
    • The goal of ASTR is to detect and block fraudulent mobile connections, thereby reducing cyber frauds.

    Development of ASTR

    • In 2012, DoT issued an order requiring telecom operators to share their subscriber database, including users’ pictures, with the department.
    • These images serve as the core database for facial recognition using ASTR.
    • The ASTR project was conceptualized and designed by the DoT’s unit in Haryana between April 2021 and July 2021.
    • A pilot project was conducted in Haryana’s Mewat region to test the feasibility of ASTR, where a significant number of fraudulent SIMs were detected.

    How ASTR works?

    • ASTR uses convolutional neural network (CNN) models to encode human faces in subscribers’ images, accounting for various factors like face tilt, angle, image opaqueness, and dark color.
    • A face comparison is performed for each face against all faces in the database, grouping similar faces under one directory.
    • ASTR considers two faces to be identical if they match to a minimum extent of 97.5%.
    • It can detect all SIMs associated with a suspected face within 10 seconds from a database of 1 crore (10 million) images.
    • After matching faces, ASTR’s algorithm utilizes “fuzzy logic” to find approximate matches for subscriber names, considering variations, typographical errors, and related results.

    Impact and Results

    • In the first phase, ASTR analyzed over 87 crore (870 million) mobile connections and detected more than 40 lakh (4 million) cases of people using a single photograph to obtain multiple connections.
    • After verification, over 36 lakh (3.6 million) connections were discontinued by telecom operators.
    • The list of fraudulent connections is also shared with banks, payment wallets, and social media platforms to disengage these numbers from their respective platforms.
    • WhatsApp collaborated with the government to disable accounts created using such numbers, and similar efforts are being made with other social media platforms.

    Facts for Prelims

    Convolutional Neural Network (CNN): A type of deep learning algorithm commonly used for image recognition tasks, where it extracts features and patterns from images by applying convolution operations.

    Fuzzy Logic: A form of logic that deals with approximate or qualitative reasoning rather than strict binary true/false values. In the context of ASTR, it is used to find similarity or approximate matches for subscriber names, accounting for variations and typographical errors.

  • Worldcoin: The Iris-scanning Cryptocurrency

    worldcoin

    Central Idea: Sam Altman, CEO of OpenAI, is reportedly raising $100 million for Worldcoin, a unique cryptocurrency.

    What is Worldcoin?

    • Worldcoin, co-founded by Altman and Alex Blania in 2019, aims to provide every human being on Earth with a share of its digital token.
    • Worldcoin is a crypto project that seeks to establish a global identity and financial network for everyone.
    • It utilizes a device called the Orb, which scans people’s irises to verify their uniqueness and humanity.
    • Individuals who undergo the iris scan are rewarded with Worldcoin tokens.
    • The World App, developed by Worldcoin, enables users to make payments, purchases, and transfers using Worldcoin and other digital assets.
    • The project plans to launch in the first half of 2023 and distribute a total of 10 billion tokens, with 80% going to users.

    Functioning of Worldcoin

    • Worldcoin’s founders aimed to freely distribute shares of the digital token to every person on the planet.
    • They envisioned it as a global distribution system for Universal Basic Income and a means to distribute profits generated by AI systems equally among people.
    • To ensure fair distribution, Worldcoin utilizes biometric iris scans through the Orb device.
    • The Orb scans the iris and converts it into a hash, which is impossible to recreate even if compromised.
    • The iris hash and the user’s public key hash are sent to Worldcoin servers, and if the person is new to the system, the hashes are added to the database and the company’s blockchain.

    Challenges and criticisms

    • Worldcoin faces challenges regarding the accessibility of the Orb and expanding the user database.
    • The project plans to incentivize sign-ups by offering coupons or access to loans.
    • Concerns exist about the privacy and security of biometric data and potential misuse.
    • Questions arise about the feasibility and scalability of reaching unbanked or underbanked populations.
    • The value and utility of the Worldcoin token and its competitiveness with other cryptocurrencies or fiat currencies are also subject to scrutiny.

    Back2Basics: Cryptocurrency

    • A cryptocurrency is a digital asset stored on computerised databases.
    • These digital coins are recorded in digital ledgers using strong cryptography to keep them secure.
    • The ledgers are distributed globally, and each transaction made using cryptocurrencies are codified as blocks.
    • And multiple blocks linking each other forms a blockchain on the distributed ledger.
    • There are estimated to be more than 47 million cryptocurrency users around the world.
    • These cryptocurrencies are created through a process called mining.
