RASS: A Concurrency-Based Bitwise Symmetric Key Cryptographic Algorithm

Cryptography, Network Security
Lead Researcher and Author

The security and strength of any cryptosystem's encryption depend on the difficulty, both in terms of time and technique, of cracking the message. This paper suggests a bit cipher, a symmetric key cryptographic algorithm which provides bit-level security with linear time complexity and robust security (two 16 bit keys), and uses optimal time compared to other such ciphers by implementing concurrency through multithreading.

January-June 2016

Segmentation-Based Image Compression

Image Processing
Research Assistant, Co-Author

In this paper, a procedure for segmentation-based image compression is suggested. Two types of segmentation techniques are used, namely threshold and region growing algorithms, and JPEG is applied to obtain the final compressed result, which provides better ratios compared to standalone compression algorithms.

July-September 2016

Hindu-Arabic Character Recognition Using Mathematical Morphology

Image Processing
Research Assistant, Co-Author

Presentation of a novel decision tree-based method to improve the ability of hand written character recognition using mathematical morphology. For this paper, classification of hand written digits is done into two groups: one with blob and another without blob. This paper proposes the recognition of digits using certain features that can distinguish one digit from the other.

I picked up my first full-length novel (Roald Dahl’s “The BFG”) when I was five, and have been reading ever since. I now read whatever I can get my hands on, primarily on my Kindle Paperwhite, and have recently found refuge in science fiction and fantasy. My favourite authors include Brandon Sanderson, Isaac Asimov, Carl Sagan, and Rick Riordan. You can find me on my Goodreads account, where I try to keep tabs on what I’m presently reading.

Mainstream media too has been a major draw for me, as an only child. I’m into comic books (The Flash being my absolute favourite), movies, TV shows as far as the eye can see, art, and documentaries. I’m also a huge fan of indie-folk and progressive rock music. I've also always been curious and opinionated, so quizzing and debating have been hobbies since my school days. I spend my time reading up on every topic under the sun, and trying as hard as I can to make it as a functioning adult in a challenging world.
