摘要

在整个被称为“数字经济”的时期,区块链在各种行业蓬勃发展,包括金融和数字版权。区块链越来越强调存储问题。为了减少对节点存储的需求,现有区块链在外部存储设备中维护块信息。区块链事务检索问题是由新的区块链存储方法引起的。当用户需要从外部存储系统下载去中心化区块链分类账信息时,问题就出现了。因为,他们无法定位包含特定事务的节点,因此这导致了巨大的通信开销。对于这个问题,我们利用区块链是半结构化的数据,并获得区块链事务的共同特征,如日期和帐户地址。接下来,我们创建一个用于检索区块链事务的方法。由于缺乏有效的特定于账户的二级搜索数据结构地址,我们建议使用可扩展的B+树。对于图像的加解密,我们采用了椭圆曲线加密算法和AES算法。对于生成哈希值,我们使用ECDSA算法。

Encrypted Image Retrieval Scheme on Blockchain
Blockchainhas flourished in a variety of industries throughout a period known as the "digital economy", including finance and digital copyright. Blockchain is highlighting the storage issue more and more. In order to lessen the demand for node storage, the existing blockchain maintains block information in external storage devices. Blockchain transaction retrieval issue is brought on by the new blockchain storage approach. The issue arises when the user is required to download the decentralized blockchain ledger information from the external storage system. Since, they couldn't locate the node comprising that particular transaction, therefore which results in significant communication overhead. We take advantage of the data that is Blockchain is semi-structured for this issue and obtain the common traits of blockchain transactions like the Date and account address. Next, we create a method for retrieving blockchain transactions. Because of the absence of an effective account-specific secondary search data structure addresses, we suggest the scalable B+ tree. For encryption and decryption of Images we have used Elliptic curve Cryptography algorithm and AES algorithm. For Generating Hash value we have used ECDSA Algorithm.
