- some information of personal credit information involves personal privacy information.
- the requester may be parsed from the personal credit information acquisition request. Verify the identity information to obtain a verification result; if the verification result is passed, output the personal credit information.
- the process of verifying the identity information of the requester may be: obtaining the digital signature of the requester, and then verifying the digital signature of the requester. Only when it is verified that the digital signature of the requester is a valid digital signature, the personal signature is output. ⁇ ⁇ Letter information. What needs to be explained here is that a digital signature is a value that is encrypted by using the requester's own private key.
- This value is unique and cannot be tampered with.
- the requester's private key is kept by the requester, only the requester or a user authorized by the requester knows the private key, so other users cannot obtain the request without the requester's authorization
- the digital signature of the requester the digital signature of the requester uniquely identifies a requester. Therefore, if the digital signature can be successfully verified using the public key corresponding to the requester's private key, the requester's identity is valid, the requester's identity is verified, and personal credit information can be output; otherwise, the request is explained If the identity of the requester is not valid, the requester's identity verification fails and the failure information can be verified.
- the technical solution proposed in this application is based on the individual credit information in the blockchain is decentralized and stored to each node, which is open.
- the information in the blockchain is open to all nodes, and the information is highly transparent. Any node in the blockchain can query the corresponding personal credit information, which makes it easier and faster to obtain personal credit information; and the personal credit information uploaded to the blockchain is stored in a chain after cryptographic processing. Traceable but not tamperable, thus ensuring the authenticity and reliability of personal credit information on the blockchain.
- any node in the blockchain can upload data to the blockchain.
- Personal credit information has a guiding role in financial industry transactions. Therefore, considering the importance of personal credit information, in order to avoid other illegal activities The staff maliciously fabricated and tampered with the personal credit information, thereby causing the problem of inaccurate personal credit information.
- This application proposes another implementation method. As shown in Figure 2, the personal credit information is packaged into blocks at any node. Before, including:
- step 104 Verify the identity of the information source to determine whether the personal credit information is valid.

- the personal credit information may be maliciously fabricated or tampered with by the illegal organization. The personal credit information is illegal and the operation of packaging the personal credit information into blocks is not performed.
- the identity of the information source is verified to determine whether the personal credit information is valid, and the identity of the information source can be verified by verifying the data signature of the information source.
- the details are as follows: before sending the personal credit information, the information source encrypts the personal credit information with its own private key, and then sends the processed personal credit information. The subject of this application obtains the encrypted information. After the personal credit information, the public key of the information source is used for decryption. If the decryption is successful, the information source identity verification is passed; if the decryption is identified, the information source identity verification fails.
- step 104 an embodiment of the present application provides another implementation manner.
- the step 104 of packaging the personal credit information into blocks specifically includes:
- the existence proof of the personal credit information is a hash value or a digest value of the personal credit information.
- the existence proof of the personal credit information is obtained by using a hash algorithm to map the binary value corresponding to the personal credit information to a fixed-length binary value, and the fixed-length binary value is the hash value.
- the time stamp is a character sequence used to identify time, which is unique and is an authentication for each change in personal credit information.
- the determination of the timestamp may be: determining the start time of packaging the personal credit information into the block as the timestamp; or determining the end time of packaging the personal credit information into the block as the timestamp; or, The personal credit information is packaged into the block body at any time within the start and end time period to determine the time stamp.
- the existence of personal credit information and the timestamp are obtained in no particular order.
- the existence of personal credit information and the timestamp can be obtained simultaneously; or the existence of personal credit information can be obtained first Proof, and then obtain the timestamp; or, you can also obtain the timestamp first, and then obtain the existence proof of personal credit information.
- the existence of personal credit information proves that the hash value has unique and compact data. Even if a piece of information changes only one letter of the information, the hash value processed by the hash algorithm will be different.
- the time stamp is stored in the block from the moment the block is generated, and is the unique time identifier of the block. Therefore, the existence of the personal credit information and the uniqueness of the time stamp can be used to ensure that the personal time stamp The information cannot be tampered with, thereby increasing the authenticity and reliability of personal credit.

104、将所述个人征信信息打包成区块。
106、将所述区块上传至区块链。
通过全网广播的方式将该区块上传至区块链,可以使得构成该区块链中的所有节点都可以接收该区块,进而实现去中心化,分布式存储,保证当区块链中的任意节点出现故障后,可以通过其他非故障节点运行。
具体的,区块链中的各节点接收到该区块后,可以直接将该区块保存到区块链的末端。或者,为了便于查看和管理每个人的个人征信信息,区块链中各节点将所述区块上传至区块链时具体可以为:获取该区块的个人标识信息,根据个人标识信息将该区块保存到该个人标识对应的区块链中。
108、接收个人征信获取请求,输出个人征信信息。
具体的,个人征信系统的区块链中包括多个人的个人征信信息,因此,在执行接收个人征信获取请求,输出个人征信信息时,为了能够快速准确的获取到对应的个人征信信息,具体可以根据个人征信获取请求中携带的个人标识,查询与个人标识对应的个人征信信息。
区块链是开发性的,区块链中的每个节点都可以下载获得完整区块链数据,也就是说,区块链中的信息对所有节点公开的,因此,将个人征信信息 上传至区块链,实现个人征信信息的高度透明化,基于区块链获取个人征信信息,能够更加方便快捷的获取到个人征信信息,而且也保证获取到的个人征信信息可靠。
另外,需要说明的是,个人征信信息存在部分信息涉及个人隐私信息,为了保证个人人身财产安全,输出所述个人征信信息之前,可以先对从所述个人征信获取请求中解析请求者的身份信息;验证所述身份信息,得到验证结果;若验证结果为通过,输出所述个人征信信息。具体上述验证请求者的身份信息的过程可以为:获取请求者的数字签名,然后,验证请求者的数字签名,只有当验证出该请求者的数字签名为有效数字签名时,才输出该个人征信信息。这里需要说明的是,数字签名是一种使用该请求者自身的私钥经过加密处理后的数值,该数值是独一无二的,且不可篡改的。另外,由于该请求者的私钥由请求者自己保管,只有请求者自己或经过请求者授权的用户知道该私钥,因此,其他用户在没有得到请求者授权的前提下,不可能得到该请求者的数字签名,请求者的数字签名唯一标识一个请求者。因此,若用与该请求者的私钥对应的公钥能够成功验证该数字签名,则说明该请求者身份合法,则该请求者身份验证通过,可以输出个人征信信息;否则,说明该请求者身份不合法,则请求者身份验证未通过,可以验证失败信息。
本申请提出的技术方案,基于区块链中的个人征信信息是去中心化分布式存储到各个节点的,具有开放性,区块链中的信息对所有节点公开,信息高度透明化,区块链中的任意节点都可以查询相应的个人征信信息,从而更加方便快捷的获取到个人征信信息;并且上传到区块链上的个人征信信息经过密码学处理后链式存储,信息可追溯但不可篡改,从而保证了区块链上中个人征信信息的真实性和可靠性。
进一步的,区块链中的任意节点都可以向区块链中上传数据,个人征信信息对金融行业的交易具有指导的作用,因此,考虑到个人征信信息的重要性,为了避免其他不法人员恶意捏造、篡改个人征信信息,从而造成个人征信信息不准确的问题出现,本申请提出了另一实现方法,如图2所示,在任意节点在将个人征信信息打包成区块之前,包括:
103、对所述信息源的身份进行验证,以确定所述个人征信信息是否有效。若所述信息源通过身份验证,表明个人征信信息是由合法机构发送的,该个人征信信息是合法的,则执行步骤104;若所述信息源未通过身份验证,表明 个人征信信息是由一些非法机构发送的,该个人征信信息可能是由该非法机构恶意捏造或者篡改的信息,该个人征信信息不合法,不执行将该个人征信信息打包成区块的操作。
在一个具体实施例中,对信息源身份进行验证,以确定个人征信信息是否有效,可以通过验证信息源的数据签名实现对信息源身份的验证。其具体为:信息源在发送该个人征信信息之前,用自己的私钥对个人征信信息进行加密处理,然后发送经过处理后的个人征信信息,本申请执行主体获取到加密处理后的个人征信信息后,用该信息源的公钥进行解密,若解密成功,则信息源身份验证通过;若解密识别,则信息源身份验证未通过。
为了进一步保证将个人征信信息上传到区块链的过程中,不会被其他非法人员篡改,从而,保证上传到区块链上的个人征信信息与信息源发送的个人征信信息相同,针对于步骤104的实现,本申请实施例提供了另一种实现方式,如图3所示,该步骤104将所述个人征信信息打包成区块具体包括:
1041、获取个人征信信息的存在性证明和时间戳。
其中,个人征信信息的存在性证明为个人征信信息的哈希值或摘要值。具体的,个人征信信息的存在性证明的获取为,利用哈希算法将个人征信信息对应的二进制值映射为的固定长度的二进制值,该固定长度的二进制值即为哈希值。
其中,时间戳是用于标识时间的字符序列,其具有唯一性,是每次个人征信信息变化的认证。具体的,时间戳的确定可以为:将个人征信信息打包到区块体的开始时间确定为时间戳;或者,将个人征信信息打包到区块体的结束时间确定为时间戳;或者,将个人征信信息打包到区块体的起止时间段内任意时刻确定时间戳。
这里需说明的是,个人征信信息的存在性证明以及时间戳的获取没有先后顺序,个人征信信息的存在性证明以及时间戳可以同时获取;或者,可以先获取个人征信信息的存在性证明,其次获取时间戳;又或者,还可以先获取时间戳,然后在获取个人征信信息的存在性证明。
另外,个人征信信息的存在性证明即哈希值具有数据唯一且紧凑,一段信息哪怕只是更改该信息的一个字母,其经过哈希算法处理得到的哈希值也将不同。而时间戳从区块生成的那一刻起就存储在区块之中,为区块的唯一时间标识,因此,利用个人征信信息的存在性证明以及时间戳的唯一性,从 而可以保证个人征信信息的不可篡改,进而个人征信的真实性和可靠性。
1042、将个人征信信息、存在性证明和时间戳打包成区块。
其中,打包生成的区块包括区块头和区块体。区块头可以标识一个区块,区块头中主要记录当前区块的特征值,即主要包含该区块的当前版本号、父区块哈希值、时间戳、Merkle根的哈希值,当前区块的哈希值(存在性证明)等数据。而区块体记录一定时间内所生成的详细数据,即个人征信信息。
结合上述基于区块链获取个人征信方法,本申请进一步给出实现上述方法的装置。具体如下:
