图2为本申请实施例提供的另一种信息校验方法的流程示意图；
图3为本申请实施例提供的一种输入待签订合同栏目要素图片的示意图；
图4为本申请实施例提供的另一种输入待签订合同栏目要素图片的示意图；
图5为本申请实施例提供的一种信息校验装置的结构示意图；
图6为本申请实施例提供的另一种信息校验装置的结构示意图；
图7为本申请实施例提供的一种比对栏目要素图片的确定方法的示意图；
图8为本申请实施例提供的另一种比对栏目要素图片的确定方法的示意图。
下面将结合图1至图8，对本申请实施例提供的信息校验方法和相关设设备进行说明。
参见图1，图1为本申请实施例提供的一种信息校验方法的流程示意图，如图所示，所述方法可以包括：
S101，根据预设的业务合同关联规则，获取与合同签订用户的待签订合同相关联的目标关联合同。
这里，所述待签订合同可以包含多个待输入的空白合同栏目，其中，所述空白合同栏目包含所述待签订合同栏目，所述待签订合同栏目对应的要素为需要与其他具有业务合同关联规则的合同中的栏目要素进行比对的栏目，所述空白合同栏目还可以包含不需要与其他具有业务合同关联规则的合同中的栏目要素进行比对的栏目，可以仅对其对应的要素进行基本形式等的校验。一种实现方式中，步骤S101的执行可以在接收到合同签订用户针对所述待签订合同的合同签订请求后触发执行的，所述合同签订请求中可以携带所述待签订合同的合同种类以及所述合同签订用户的身份标识，根据预设的业务合同关联规则以及所 述待签订合同的合同种类，确定与所述待签订合同相关联的关联合同种类，从预设的已签订合同数据库中或预设的合同签订区块链上的合同记账节点中存储的所述关联合同种类的已签订合同中获取与所述身份标识匹配的目标关联合同。
所述待签订合同的合同种类可以根据具体的业务场景的不同而设定不同的种类，例如在供应链金融的业务场景中，所述合同种类可以包括授信合同种类、借款合同种类、贸易合同种类等。所述合同签订用户的身份标识可以为所述合同签订用户本人的姓名、身份证件标识等，也可以为所述合同签订用户所代表的合同主体的标识，例如所述身份标识可以是所述合同签订用户所代表的企业的企业名称、组织机构代码等。相应的，所述业务合同关联规则可以根据不同的业务场景而不同，例如在中小企业等融资方向出资方融资时，需要签订借款合同，所述业务合同关联规则可以为借款合同种类与授信合同种类互相关联；在出资方向中小企业授信时，需要签订授信合同，所述业务合同关联规则可以为授信合同种类与贸易合同种类互相关联。若获取的所述待签订合同的合同种类为借款合同种类，则根据预设的业务合同关联规则，与借款合同相关联的关联合同种类为授信合同种类。
另一种实现方式中，所述目标关联合同为所述合同签订用户自行上传的。
可以理解的是，所述待签订合同栏目可以包含多个，可以针对所述多个待签订合同栏目设定各自对应的目标关联合同。各个待签订合同栏目对应的目标关联合同可以相同，也可以不同。
S102，获取所述目标关联合同中比对合同栏目对应的比对栏目要素。
所述比对合同栏目为预设的与所述待签订合同中待签订合同栏目有业务对应关系的栏目，所述比对栏目要素为所述比对合同栏目中的栏目值。这里，可以根据预设的针对所述目标关联合同中所述比对栏目要素的位置标签或关键字标签，确定所述比对栏目要素在所述目标关联合同中的位置；根据所述比对栏目要素在所述目标关联合同中的位置，获取所述比对合同栏目中的比对栏目要素。
例如，所述待签订合同为借款合同，所述待签订合同栏目为甲方信息栏目，所述目标关联合同的比对合同栏目为授信合同中的甲方栏目，若授信合同中的甲方信息栏目对应的甲方信息的位置标签为“第1页第[001]段中第三个字符之后的各个字符”，根据所述甲方信息的位置标签从所述授信合同中确定甲方信息的位置，进而获取第一页第二段中的第三个字符之后的各个字符作为所述甲方信息栏目对应的甲方信息。若授信合同中的甲方信息栏目对应的甲方信息的关键字标签为“甲方：”，在所述授信合同中检索所述关键字标签“甲方：”后，将“甲方：”之后的连续字符串确定为所述甲方信息进而获取所述甲方信息，这里可以将所述连续字符串定义为没有标点符号、换行符或空格符分隔的字符串。
具体的，所述目标关联合同中所述比对合同栏目对应的比对栏目要素可以为图片存储在所述目标关联合同中，所述目标关联合同可以为以文档或图片等形式存储的，可以根据所述对比栏目要素在所述目标关联合同中的位置，获取所述对比合同栏目对应的比对栏目要素图片；通过光学字符识别技术识别所述比对栏目要素图片中的比对栏目要素。具体的，若所述目标关联合同以word文档格式存储，所述比对栏目要素图片以文档中插入的图片的 形式存储在所述目标关联合同中，可以在所述比对栏目要素在所述目标关联合同中的位置复制得到所述比对栏目要素图片；若所述目标关联合同以JPG等图片格式或PDF文档格式等图片形式存储的，可以在所述比对栏目要素在所述目标关联合同中的位置截取得到所述比对栏目要素图片。
具体的，若目标关联合同为以图片形式存储，根据所述比对栏目要素的位置标签确定的所述比对栏目要素在所述目标关联合同中的位置，为所述比对栏目要素对应的比对栏目要素图片的截取起始像素在所述目标关联合同中的位置，可以从所述截取起始像素在所述目标关联合同中的位置为起点，按照预设的图片截取方向截取预设尺寸的图片，得到所述比对栏目要素图片。例如，如图7所示，为一种比对栏目要素图片的确定方法的示意图，其中，S点为所述截取起始像素，预设的图片截取方向包括从S点先向下再向右截取，以及从S点先向右再向下截取，所述预设尺寸包括从S点先向下截取200个像素的长度，再向下截取400个像素的长度，和从S点先向右截取400个像素的长度，再向下截取200个像素的长度，即将区域M截取后得到所述比对栏目要素图片。
若目标关联合同为以图片形式存储，另一种实现方式中，所述截取起始像素可以为所述比对栏目要素的外围边框上的一个像素点，可以基于所述截取起始像素进行边缘检测，获取所述比对栏目要素的外围边框，进而沿所述比对栏目要素的外围边框进行截取，得到所述比对栏目要素图片。例如，如图8中所示，为另一种比对栏目要素图片的确定方法的示意图，其中T点为所述截取起始像素，通过边缘检测技术，确定所述比对栏目要素的外围边框，将比对栏目要素的外围边框围城的区域N截取后，得到所述比对栏目要素图片。
一种可选的实现方式中，在步骤S102之前，可以获取所述目标关联合同的关联合同签订者通过关联合同签订者的电子签章设备对所述目标关联合同的电子签名，所述目标关联合同的电子签名为所述关联合同签订者通过预设的第二电子签章设备私钥对所述目标关联合同进行哈希运算后得到的哈希值进行加密后得到的。获取所述目标关联合同的电子签名之后，通过预设的与所述第二电子签章设备私钥相对应的第二电子签章设备公钥对所述目标关联合同进行解密，并对所述目标关联合同进行哈希运算，在确定得到的哈希值与所述解密后的所述目标关联合同的电子签名一致的情况下，确定所述目标关联合同为有效目标关联合同，进而从所述有效目标关联合同中获取所述比对栏目要素。
S103，当接收到所述合同签订用户针对所述待签订合同栏目输入的待签订合同栏目要素图片时，通过光学字符识别技术获取所述待签订合同栏目要素图片中包含的待签订合同栏目要素。
这里，所述合同签订用户可以即时通过预设的手写屏幕针对所述待签订合同栏目进行书写输入所述待签订合同栏目要素图片，也可以是输入的预先存储针对所述待签订合同栏目的待签订合同栏目要素图片。当接收到所述待签订合同栏目要素图片后，立即执行通过光学字符识别技术获取所述待签订合同栏目要素图片中包含的待签订合同栏目要素，以及之后的步骤，以保证对用户输入的待签订合同栏目要素校验的时效性。
S104，根据所述比对栏目要素对所述待签订合同栏目要素进行校验。
具体的，根据所述比对栏目要素对所述待签订合同栏目要素进行校验的校验方式，根据所述待签订合同栏目要素对应的待签订合同栏目的不同而不同，可以预先针对不同的待签订合同栏目设置不同的校验方式，例如，若所述待签订合同栏目为合同签订方信息栏目，针对所述合同签订方信息栏目预设的校验方式为校验所述合同签订用户输入的合同签订方信息与从所述目标关联合同中获取的合同签订方信息是否一致，若不一致，则确定校验不通过；若所述待签订合同栏目为借款金额栏目，针对所述借款金额栏目预设的校验方式为校验所述合同签订用户输入的借款金额是否大于从所述目标关联合同中获取的授信额度，若是，则确定校验不通过。
S105，在校验不通过的情况下，返回针对所述待签订合同栏目的输入无效提示，所述输入无效提示用于提示所述合同签订用户重新输入针对所述待签订合同栏目的要素。
这里，在所述待签订合同包含多个空白合同栏目时，所述针对所述待签订合同栏目的输入无效提示可以在所述合同签订方签订输入完成所述待签订合同栏目后，输入所述空白合同栏目中所述待签订合同栏目以外的其他空白合同栏目对应的要素之前，向所述合同签订用户返回，使所述待签订合同用户针对所述待签订合同栏目输入满足校验通过条件的待签订合同栏目要素时，允许所述合同签订用户针对所述空白合同栏目中所述待签订合同栏目以外的其他空白合同栏目输入要素。也可以在所述合同签订用户完成签订后触发所述待签订合同的提交请求时，返回针对所述待签订合同栏目的输入无效提示，使所述合同签订用户针对所述待签订合同栏目输入满足校验通过条件的待签订合同栏目要素后，提交签订完成的所述待签订合同。实现了在所述合同签订用户签订合同的过程中校验针对所述待签订合同栏目输入的待签订合同栏目要素，并在确定校验不通过的情况下，及时返回输入无效提示，保证了待签订合同的签订和修正的时效性。
可选的，根据所述比对栏目要素对所述待签订合同栏目要素进行校验之前，还包括：校验所述待签订合同栏目要素是否符合预设的针对所述待签订合同栏目的输入格式规则；在确定所述待签订合同栏目要素符合所述输入格式规则的情况下，执行所述根据所述比对栏目要素对所述待签订合同栏目要素进行校验。例如，若所述待签订合同栏目要素包含合同金额大写栏目要素，对应的输入格式规则可以为所述合同金额大写栏目要素中的字符为壹、贰、叁、肆、伍、陆、柒、捌、玖、拾、佰、仟、万、亿、元、圆、角、分、零、整中的一个或多个。
可选的，在校验通过的情况下，允许合同签订用户针对所述待签订合同进行电子签章，具体实现中：接收所述合同签订用户的电子签章设备发送所述合同签订用户的签章图片；将所述合同签订用户的签章图片设置在所述待签订合同的指定签章区域并将所述当前系统时间显示在指定时间区域后，生成所述合同签订用户的已签订合同；将所述合同签订用户的已签订合同发送给所述合同签订用户的电子签章设备，以使所述合同签订用户的电子签章设备通过预设的第一电子签章设备私钥对所述合同签订用户的已签订合同进行哈希运算得到的哈希值进行加密，得到所述合同签订用户对所述合同签订用户的已签订合同的电子签名；接收所述合同签订用户的电子签章设备发送的所述已签订合同的电子签名，所述已 签订合同的电子签名被用于通过预设的第一电子签章设备公钥解密后，在验证对所述合同签订用户的已签订合同进行哈希运算得到的哈希值与所述解密后的所述已签订合同的电子签名一致时，确定所述合同签订用户的已签订合同为有效合同。
进一步可选的，在将所述合同签订用户的签章图片设置在所述待签订合同的指定签章区域并将所述当前系统时间显示在指定时间区域之前，还可以接收所述合同签订用户的电子签章设备发送的电子签章数字证书，所述电子签章数字证书为可信任的证书发布方组织对所述合同签订用户或所述合同签订用户所代表的合同主体进行身份认证后，颁布的代表所述合同签订方用户或所述合同签订用户所代表的合同主体的身份的数字证书；进而根据所述电子签章数字证书对所述合同签订用户的电子签章设备进行身份认证，在所述身份认证通过的情况下，将所述合同签订用户的签章图片设置在所述待签订合同的指定签章区域并将所述当前系统时间显示在指定时间区域。
这里，根据所述电子签章数字证书对所述合同签订用户的电子签证设备进行身份认证可以包括：对所述电子签章数字证书中包含的所述电子签章数字证的发布方的发布方信息进行验证，在根据所述发布方信息确认所述发布方为可信任发布机构的情况下，通过所述发布方对应的发布方公钥，对所述电子签章数字证书中包含的所述电子签章数字证书的数字签名进行解密，并将所述电子签证数字证书进行哈希运算，在确认对所述电子签章数字证书进行哈希运算得到的哈希值与解密后的所述电子签章数字证书的数字签名一致的情况下，确认所述电子签章数字证书为未被篡改的可靠电子签章数字证书；在确认所述电子签章数字证书为可靠电子签章数字证书之后，向所述电子签章数字证书发送身份测试随机消息，以使所述合同签订用户的电子签证设备返回通过所述预设的第一电子签章设备私钥对所述身份测试随机消息进行加密的加密身份测试随机消息；通过所述电子签章数字证书中包含的第一电子签章设备公钥对所述加密身份测试随机消息进行解密后，验证与向所述合同签订用户的电子签章设备发送的所述身份测试随机消息是否一致，在一致的情况下，确认根据所述电子签章数字证书对所述合同签订用户的电子签证设备进行的身份认证通过。
本申请实施例中，在根据预设的业务合同关联规则，获取与合同签订用户的待签订合同相关联的目标关联合同后，获取所述目标关联合同中比对合同栏目对应的比对栏目要素，在接收到合同签订用户针对所述待签订合同栏目输入待签订合同栏目要素时，通过光学字符识别技术获取所述待签订合同栏目要素图片中包含的待签订合同栏目要素，并根据所述比对栏目要素对所述待签订合同栏目要素进行校验，在校验不通过的情况下，返回针对所述待签订合同栏目的输入无效提示。实现了在合同签订用户签订合同的过程中实时自动化地校验合同签订用户输入的待签订合同栏目要素，提高了合同信息校验的时效性和准确度。
参见图2，图2为本申请实施例提供的另一种信息校验方法的流程示意图，如图所示，所述方法可以包括：
