Online Transactions
Online Transactions
Online transactions are a fundamental component of the digital economy, enabling the exchange of goods and services over the Internet. They involve the execution of a program that performs administrative functions by accessing a shared database, typically on behalf of an online user. These transactions are crucial in various spheres such as e-commerce, online banking, and online marketplaces.
Components and Process
The process of an online transaction generally involves multiple steps such as recording the sale of an item, reserving it from inventory, and processing payment. This sequence of actions is executed through Online Transaction Processing (OLTP), which is designed to handle a high volume of transactions in real-time, ensuring efficiency and accuracy.
Networking Protocols
Online transactions heavily rely on networking protocols. The Hypertext Transfer Protocol (HTTP) and its secure counterpart, Hypertext Transfer Protocol Secure (HTTPS), are foundational to these transactions. HTTPS combines HTTP with Secure Sockets Layer (SSL) or Transport Layer Security (TLS) to provide encryption and server authentication, safeguarding data transmission between endpoints.
Security in Online Transactions
Security is paramount in online transactions. Various cryptographic methods protect the information exchanged. Hash functions, such as the Secure Hash Algorithm 256 (SHA-256), ensure data integrity by generating unique signatures for data. Elliptic Curve Cryptography (ECC) is employed for digital signature generation and transaction verification, offering robust security and efficiency.
Applications
-
E-Commerce: Online transactions facilitate consumer purchases through platforms like Amazon and eBay. These platforms utilize secure payment gateways to process transactions.
-
Online Banking: Allows users to manage their finances via financial institution websites or mobile apps, offering services like fund transfers and bill payments.
-
Online Marketplaces: Platforms such as Alibaba and Etsy connect buyers and sellers, enabling complex transactions like requests for quotations and proposals.
-
Online Dispute Resolution: This mechanism is applied to resolve conflicts arising from business-to-consumer (B2C) transactions, providing a structured process for conflict management.
Emerging Technologies
The landscape of online transactions is continuously evolving with advancements such as blockchain technology, which promises to enhance transparency and security by providing a decentralized ledger for recording transactions. Furthermore, the integration of artificial intelligence (AI) and machine learning is set to optimize transaction processes and fraud detection.
