Song-search-using-audio-fingerprinting-based-on-Shazam-algorithm
Implemented a song search engine, resistant to noise, computationally efficient, and massively scalable, capable of quickly identifying a song using a short segment of music captured by a cellphone microphone in the presence of foreground voices and other dominant noise, out of a database of millions of tracks. The algorithm uses a combinatorially hashed time-frequency constellation analysis of the audio, yielding unusual properties such as transparency, in which multiple tracks mixed together may each be identified. Furthermore, for applications such as radio monitoring, search times on the order of a few milliseconds per query are attained, even on a massive music database.

orked on Bitcoin Testnet blockchain and Ethereum smart contracts using python-bitcoinlib and solidity respectively, in order to submit transactions and contracts for different scenarios like cross-chain atomic swap allowing two entities to securely trade ownership over cryptocurrencies on different blockchains.
Foundations-of-Cryptography-and-Network-Security-Course-Project
Developed software for storing confidential information of users, with various features such as registering new users and changing the accounts passwords through the implementation of AES as the symmetric encryption algorithm and SHA3-512 as the hash function.
Game-Theory-Course-Project
Designed and simulated the best solution for allocating patients of two types to different hospitals, once based on the optimal mechanism for maximizing hospitals' total income and once based on stable matching, both with and without considering death possibility.
Computer-Vision-Course-Project
Developed software to synopsis videos of surveillance cameras through detecting moving objects, tracking them during their presence in the video, constructing temporal-spatial tubes of them, and finally reconstructing the video with more density of objects.
