Cryptography for cyber security
The only way to effectively deal with cyber threats is to adopt robust cryptographic techniques. Cryptography is the science of using mathematical techniques for securing digital information and communication. Cryptography offers solutions to everyday problems like social media privacy breaches, cyber-bullying banking frauds, and online identity theft.
During II SC open day, I encourage my students to create puzzles derived from crypto concepts. I see high school students get totally fascinated by them. It would be a good idea to give students a small dose of crypto in 11th and 12th standard. A good understanding of math is crucial for anyone interested in this field. Modern cryptographic protocols rely on mathematical principles from areas such as discrete mathematics, linear algebra and coding theory.

Ornamental masks new trend
Bejeweled masks, studded with gold, silver, and platinum are giving stiff competition to traditional jewellery across the world. A shop in Surat India is selling masks studded with real diamonds for Rs.1.5 to 4 lakh. Designer Kajal Khurrana from Delhi says, “Women are increasingly buying masks studded with rhinestone and sequins and even sapphire, diamonds and emeralds, though one has to ensure that they are up to safety standards. “Instead of regular jhumukkas, matha pattis and naths, blinky masks can redefine your festive look." These luxury masks push ornament merchants.
