Blockchain solution

Now combat spam calls with blockchain

Aligning itself with the Telecom Regulatory Authority of India (TRAI)‘s regulations to protect mobile phone subscribers from unsolicited Commercial Communication (UCC) or spam calls, Tech Mahindra announced that it was deploying its Blockchain solution to help more than 300 million mobile subscribers in India.

The regulations are expected to kick in from the last week of May, and Mahindra’s solution will combat the epidemic that is spam calls. Tech Mahindra has designed the Blockchain solution last year, which will enable telecom providers to prevent unauthorized access of subscriber data.

In a press note issued by the company, Tech Mahindra said it is demonstrating Blockchain capabilities in sectors across telecom, manufacturing, hi-tech industries, and financial services. The company has a team of 50 people across Bengaluru, Hyderabad, and Chennai, who are involved in writing the blockchain code. The company is in discussions with telco operators outside India to tap global customers as well. With 800 million subscribers who would get impacted by the TRAI regulation, this could be world’s largest use case for a blockchain solution in this space.

When it comes to spam calls, Indians possibly have the hardest time tackling it. According to Sweden-based phone-identification number app Truecaller, India is the second most spam plagued the country in the world in 2018. India’s average Truecaller user received 22.3 spam calls per month in 2018 down from 22.6 last year. Brazil has taken over India in 2018 with 37.5 spam calls per month up from 20.7 calls, an 81 percent increase in spam calls in a year.

More than six percent of overall calls received by Indian users in 2018 were spam calls. As far as the breakdown of spam call categorization in India is concerned, there has been a substantial increase of spam calls (91 percent) coming from operators/telecom service providers upselling various offers and balance reminders, according to the Truecaller report.
