Abstract

The blockchain is an intelligent and cryptographically secure technology. Blockchain provides data integrity, security, and anonymity without any third-party enabling immutable database technology with a built-in trust mechanism. In this paper, we focused on utilizing blockchain technology for proving the origin of digital media by enhancing the functionality of an existing solution. This research improves the functionality of the existing solution by using perceptual hashing. Perceptual hashing ables to differentiate similar digital media and ensures the explicit relationship between the digital media and the content creator. Experimental results show that perceptual hashing gives better performance in the detection of image alteration and sensitive to small changes.
基于区块链的数字媒体来源证明方法
区块链是一种智能且加密安全的技术。区块链提供数据完整性,安全性和匿名性,无需任何第三方启用不可变数据库技术,内置信任机制。在本文中,我们专注于利用区块链技术通过增强现有解决方案的功能来证明数字媒体的起源。本研究通过使用感知哈希改进了现有解决方案的功能。感知哈希表用于区分类似的数字媒体,并确保数字媒体和内容创建者之间的明确关系。实验结果表明,感知哈希算法在检测图像变化方面具有较好的性能,并且对微小的变化敏感。
