摘要: 文中提出了一种基于区块链存储的音频版权存证模型,它使得音频作品可以独一无二地存证于不可篡改的区块链上,中间不需要通过额外的版权代理机构。唯一标识一段音频的音频指纹虽然可以部分解决版权存证中盗版等问题,但是如果仍然需要中心化平台的支持才能杜绝盗版的话,那么版权保护仍然存在效率低下、不透明和不可信等问题,因而失去了价值。在此提出“区块链+音频指纹”的解决方案,从版权登记入口预防版权盗用,为建立数字版权交易平台以及解决版权交易信息不透明等问题提供技术基础。该模型基于区块链不可篡改、可溯源的先天优势,将产生的音频指纹压缩拆分、加入时间戳,通过用户私钥签名,构造出基本的作品发布证明,发送给区块链的每个节点,节点进行签名确认、打包进区块,完成存证。
