New Delhi: Tech Mahindra and Microsoft have partnered to develop blockchain-based technology to curb annoying calls and SMS as recommended by the Telecom Regulatory Authority of India (TRAI).
"Tech Mahindra … today announced its collaboration with Microsoft to create a solution based on Distributed Ledger Technology (DLT) technology to build a robust ecosystem in line with the regulations issued by the TRAI", says a joint statement by the two society.
Based on blockchain technology and built on Microsoft Azure, the solution aims to mitigate the issue of unsolicited commercial communication (UCC) in the country, he said.
Under the new TRAI rules to quell annoying calls, telecommunications operators are required to implement blockchain-based technology to prevent unauthorized access to subscriber data, make the system non-repudiation and improve confidentiality.
Apparently it is the first technology in the world to be distributed to prevent the leakage of consumer information by unauthorized telemarketing.
"Blockchain as a technology is a powerful tool to combat the problem of spam calls and fraud risks, to protect user information, as well as the integrity of the telecommunications industry.
" This solution based on DLT will allow companies to block financial fraud and the perpetration of misleading financial information from unregistered mobile phone operators who make rational use of the SMS telco service, "said Rajesh Dhuddu, Global Practice Leader, Blockchain , Tech Mahindra.
The new TRAI rules aim to ensure that subscriber data is not visible to the person using the clear text system or any other application "other than the application to perform the delegated functions".  The regulator stated that the UCC or spam calls are a major nuisance for telecommunications subscribers and worked with the interes to curb this threat.
TRAI had set up a "Do Not Disturb" (DND) register in 2010. However, while the register has more than 23 crore subscribers, unregistered telemarketing continues to send spam to customers, obtaining their consent through fraudulent tactics.
"Tech Mahindra and Microsoft have been working with TRAI on this issue since this regulation was formally structured," reads the statement.
Any change to a system based on blockchain is reflected on the whole system or connected computers
The solution based on blockchain will allow the telcos and registered telemarketing to deal with registration of preferences, acquisition of consent, setting preferences dynamics, inclusion of stakeholders, registration of headers, registration of the template, service of rip-off, management and tracking of complaints, states the statement.
The solution will be a shared and secure ledger of UCC distribution through a computer network, which will ensure a transparent and verifiable system to help companies mitigate UCC on their networks.
"Through this solution we will be able to help service providers comply with the new regulation.With a Microsoft Azure blockchain solution, we will make sure to mitigate the flaws used by scammers and spammers to reach end users" , said Prashant Shukla, national technical manager, Microsoft India
