Context: The Telecom Regulatory Authority of India (TRAI) will be using distributed ledger technology (DLT) to register spam preferences from customers, in order to reduce spam.
Relevance of the Topic: Prelims: Spams, associated challenges and role of TRAI in controlling them.
What are Spams?
- Spams or Unsolicited Commercial Communications (UCC) refer to any unsolicited, usually irrelevant or inappropriate messages, sent over digital channels like email, SMS, or social media.
- Acts involved in spamming:
- Bulk messaging
- System generated phone calls
- Identity theft
Issues associated with spams in India
- Privacy invasion: Spam calls often involve the collection of personal data. E.g., Fake lottery scams request sensitive information like bank details.
- Harassment: Persistent unsolicited calls for marketing disturb consumers leading to frustration of customers.
- Financial fraud: Spammers use misleading offers such as fake loan schemes, to defraud individuals by convincing them to share financial or personal details.
- Phishing: Using fraudulent messaging or calls to trick people with authentic looking phone numbers and system domains.
- Evolving methodology: The spam operators continuously change the modus-operandi and content modulation to breach blocking.

Initiatives to Control Spam
- Do not Disturb (DND): TRAI has initiated the “do not disturb” policy for consumers allowing them to block commercial communications.
- AI-driven Anti-Spam mechanism: Telecom providers use AI to detect and block spam messages in real-time. E.g., Airtel initiative to declare suspicious calls using AI as “suspected spam”.
- Blockchain usage: Using blockchain ledgers to protect sensitive information. E.g., Changing variables to spaced or masking of variables like “Your OTP is 112132” will be changed to “Your OTP is *******” to protect sensitive information.
- Complaint Portal: Department of Telecommunications has launched the Sanchar Sathi portal which has a reporting site called Chakshu for complaining of spam calls.
- Migration for Telemarketing calls to Distributed Ledger Technology platform: With effect from October 2024, Telemarketing calls starting with the 140xx numbering series have been migrated to the DLT platform for strict monitoring and control.
- DLT platform is a block-chain based registration system adopted to keep records of all transactions exchanged between network participants.
Acts to Combat Spam in India
- Telecom Commercial Communications Customer Preference Regulations (TCCCPR), 2018: This sets guidelines for telemarketers, ensuring that only opted-in customers receive marketing calls or messages.
- Information Technology (Reasonable Security Practices and Procedures and Sensitive Personal Data or Information) Rules, 2011: Regulates the collection, processing, and storage of personal data to prevent misuse for spamming.
- Telecom Regulatory Authority of India (TRAI) Act, 1997: Empowers TRAI to regulate telecommunication services, including measures against spam.

What more can be done?
- Stronger penalties: Enforcing higher penalties for spammers, such as the US introduced penalties like the Telephone Consumer Protection Act.
- Special numbers: Introducing special and designated numbers or code for the financial intermediaries.
- Consumer awareness: Spreading awareness among people about consumer rights and means to block spam numbers. E.g., European Union’s anti-spam measures to empower people.
- Strengthening VoI: The voice over internet monitoring to control spam needs to be strengthened by authenticating genuine numbers.
