From Centralization To Decentralization: Blockchain's Role In Transforming Social Media Platform Page

Abstract

The Growing Dependence On Social Media Platforms For Day-to-day Communication Has Made Digital Privacy A Serious Concern. Platforms Such As Instagram, Twitter, And Facebook Host Vast Amounts Of User-generated Content, Including Images, Text, And Metadata, Much Of Which Can Unintentionally Expose Personal Details. Despite The Available Privacy Controls, These Tools Often Fall Short Of Preventing The Misuse Or Unauthorized Distribution Of Sensitive Content. This Study Presents A Secure Image-sharing Framework That Combines Wavelet-SVD-based Watermarking, Steganography, And Blockchain Technology To Address These Vulnerabilities. The System Supports Image Categorization, Invisible Watermark Embedding, And Screen-shot Prevention. Blockchain Ledgers Ensure Tamper-proof Storage Of Image Ownership Records, Whereas The Dual-layered Security Approach Makes The Unauthorized Extraction Of Hidden Content Extremely Difficult.
