7. Blockchain Technology & Cryptography

A blockchain is a digital ledger consisting of records called blocks that are used to record transactions across many computers so that any involved block cannot be altered retroactively, without the alteration of all subsequent blocks. This enables participants to independently verify and audit transactions in a cost-effective manner. By utilizing blockchain technology, the issue of infinite reproducibility in digital assets is eliminated. A blockchain can uphold title rights by accurately documenting exchange agreements, ensuring a clear record of offer and acceptance. 

Cryptography is a practice and study of techniques to secure communication in the presence of adversarial behavior. More generally, cryptography is about constructing and analyzing protocols that prevent or detect illicit behavior; aspects of information security such as data confidentiality, data integrity, authentication, and non-repudiation are central to modern cryptography. Modern cryptography combines elements of mathematics, computer science, and electrical engineering. It is widely used in applications such as ATM cards, computer passwords, and e-commerce.

8. Robotics & Automation Engineering

Robotics and Automation Engineering is a multidisciplinary field that combines principles from mechanical engineering, electrical engineering, computer science, and artificial intelligence to design, build, and program robots and automated systems.
