Calling Name Presentation - The Hindu - 08/12/22

Context:
Recently, the Telecom Regulatory Authority of India (TRAI) has proposed the introduction of Calling Name Presentation (CNAP).
Relevance:
GS2
About:
he feature would provide the called individual with information about the calling party (similar to ‘Truecaller’ and ‘Bharat Caller ID & Anti-Spam’).
The idea is to ensure that telephone subscribers are able to make an informed choice about incoming calls and curb harassment by unknown or spam callers.

What is its Purpose:
-Existing technologies present the number of the calling entity on the potential receiver’s handset.
-Since subscribers are not given the name and identity of the caller, they sometimes choose not to answer them believing it could be unsolicited commercial communication from unregistered telemarketers. This could lead to even genuine calls being unanswered.

Challenges:-
1.Latency:
There is a likelihood of a slight increase in the time taken to set up a call.
The responsiveness might also suffer when moving from a faster wireless network (4G or 5G) to a comparatively slower one (2G or 3G), or vice-versa.
2.Privacy:
It is not particularly clear how the (CNAP) mechanism would balance the caller’s right to remain anonymous, an essential component of the right to privacy.
