Indian mobile operators are exploring using blockchain technology to help curb unsolicited calls and SMS, in response to recommendations from regulator Trai.
The Cellular Operators Association of India (COAI), the industry body representing all remaining major operators, is looking at presentations from various vendors regarding their blockchain-based solutions to the problem of unsolicited communications, the Economic Timesreported.
COAI is focused on ensuring that an implementation will be industry-wide, the body's director general Rajan Mathews told the publication.
Trai has introduced new rules requiring operators to deploy blockchain-based technology to prevent unauthorized access of subscriber data.
The regulator has meanwhile been working to curb unsolicited communications for years, having introduced a do not call registry in 2010 that now has more than 230 million users. But unregistered telemarketers continue to contact customers after obtaining numbers and consent through fraudulent means.
Blockchain is seen as a solution to this problem by helping curb fraud by unregistered telecom marketers. Microsoft and Indian ICT vendor Tech Mahindra have announced that they will collaborate on a blockchain-based solution to address the same issue.
