New Delhi, November 18, 2016: The Indian Navy on Friday inducted four indigenous sonars to give a boost to its underwater surveillance capability.

The systems are Abhay — a Compact Hull Mounted Sonar for Shallow Water Crafts; Humsa UG, an upgrade of the Humsa Sonar System; NACS or Near-field Acoustic Characterisation System; and AIDSS or Advanced Indigenous Distress Sonar System for submarines.

NewsGram brings to you latest new stories in India.

Defence Minister Manohar Parrikar and Navy chief Admiral Sunil Lanba were present on the occasion.

The sonars have been designed and developed by Naval Physical and Oceanographic Laboratory, a Kochi-based premier laboratory of Defence Research and Development Organisation.

Abhay is an advanced active-cum-passive integrated sonar system designed and developed for smaller platforms such as shallow watercrafts and coastal surveillance and patrol vessels.

Using the latest technology in hardware architecture and advanced signal processing algorithms, the sonar is capable of detecting, localising, classifying and tracking sub-surface and surface targets in both active and passive modes of operation.

The prototype of this compact sonar installed onboard a nominated naval platform has successfully completed all user-evaluation trials to demonstrate the features as per the Naval Staff Qualification Requirements.

Humsa UG has hardware architecture based on the state-of-the-art open architecture processor technologies to enable smooth upgrade of the system capabilities.

This system is proposed to be installed on seven ships of three classes of ships.

NACS determines the in-situ performance of the sonar system used to find the frequency-dependent 3-D transmission and reception characteristics of the sonar.

It is also used to measure the magnitude and phase characteristics of the sonar transmission and reception electronics and transducers.

AIDSS is a distress Sonar or an emergency sound signalling device used to indicate a submarine in distress and enable quick rescue and salvage.

It is a life-saving alarm system designed to transmit sonar signals of a pre-designated frequency and pulse shape in an emergency situation from a submarine for long period.

A Memorandum of Understanding was signed between the ministries of defence and skill development in July 2015 to enhance the skill sets of retiring defence personnel.

In the pilot batch, 70 retiring naval personnel have been trained in collaboration with the National Skill Development Corporation, the Indian Navy said.

Parrikar along with Skill Development Minister Rajiv Pratap Rudy handed over skill certificates to retiring naval personnel on the occasion. (IANS)

Aadhaar Helpline Mystery: French Security Expert Tweets of doing a Full Disclosure Tomorrow about Code of the Google SetUP Wizard App

Google comes up with a new feature

Google’s admission that it had in 2014 inadvertently coded the 112 distress number and the UIDAI helpline number into its setup wizard for Android devices triggered another controversy on Saturday as India’s telecom regulator had only recommended the use of 112 as an emergency number in April 2015.

After a large section of smartphone users in India saw a toll-free helpline number of UIDAI saved in their phone-books by default, Google issued a statement, saying its “internal review revealed that in 2014, the then UIDAI helpline number and the 112 distress helpline number were inadvertently coded into the SetUp wizard of the Android release given to OEMs for use in India and has remained there since”.

However, the Telecom Regulatory Authority of India (TRAI) recommended only in April 2015 that the number 112 be adopted as the single emergency number for the country.

According to Google, “since the numbers get listed on a user’s contact list, these get  transferred accordingly to the contacts on any new device”.

Google was yet to comment on the new development.

Meanwhile, French security expert that goes by the name of Elliot Alderson and has been at the core of the entire Aadhaar controversy, tweeted on Saturday: “I just found something interesting. I will probably do full disclosure tomorrow”.

“I’m digging into the code of the @Google SetupWizard app and I found that”.

“As far as I can see this object is not used in the current code, so there is no implications. This is just a poor coding practice in term of security,” he further tweeted.

On Friday, both the Unique Identification Authority of India (UIDAI) as well as the telecom operators washed their hand of the issue.

While the telecom industry denied any role in the strange incident, the UIDAI said that he strange incident, the UIDAI said that some vested interests were trying to create “unwarranted confusion” in the public and clarified that it had not asked any manufacturer or telecom service provider to provide any such facility.

Twitter was abuzz with the new development after a huge uproar due to Telecom Regulatory Authority of India (TRAI) Chairman R.S. Sharma’s open Aadhaar challenge to critics and hackers.

Ethical hackers exposed at least 14 personal details of the TRAI Chairman, including mobile numbers, home address, date of birth, PAN number and voter ID among others. (IANS)
