Blockchain based Digital Multimedia Content Authentication System: using IPFS and Ethereum

In the era of digital technology, the widespread availability of multimedia content has presented major challenges in confirming the genuineness and reliability of digital media. This paper introduces a novel technology that utilizes the InterPlanetary File System (IPFS) and Ethereum to authenticate multimedia content, ensuring its provenance and prohibiting tampering. The suggested approach brings together a decentralized ledger system with cryptographic hashing and smart contracts to create an immutable record of content ownership and modification history. By integrating cryptographic hashes of multimedia files into blockchain transactions, we establish a secure, transparent, and tamper-proof mechanism for tracking content authenticity. Our methodology improves confidence and dependability in digital media by establishing a strong structure for creators, distributors, and consumers to authenticate the authenticity of multimedia materials. Experimental results confirm the effectiveness and efficiency of our system in preserving the integrity of various types of multimedia content, laying the path for a wider utilization areas such as digital rights management, content distribution, and forensic analysis, etc.
