The Indian government has launched a nationwide e-mail blacklisting scheme, in the wake of a slew of cyberattacks targeting its e-commerce and government websites.
The government has also decided to make Aadhaar mandatory for most transactions in the country.
The move follows a report that the Aadhaar card is linked to a range of bank accounts and financial institutions in India.
The new blacklisting initiative is part of a larger campaign to crack down on cybercrime and theft, according to the National Crime Records Bureau (NCRB).
In November, India reported a total of 564,566 cyber attacks against its government websites, according the NCRB.
The National Crime Information Bureau, a body that tracks crimes and frauds across the country, said the majority of cyber attacks occurred in October, with the number of attacks rising in November, but remained at a low level of 1,874 in November and December.
It said there was a trend towards targeting government websites and services through various methods, including phishing and hacking, as well as attempts to steal private information.
India is among a growing number of countries that are considering or implementing e-government schemes, as they attempt to tackle the increasing burden of digital transactions.
It has seen a surge in e-wallets, which enable users to deposit and withdraw money from online payment providers, and digital payment systems, such as PayPal, which allow users to make payments.
