    • In an approach to caller ID verification by digital signature, a computing device receives authenticating information associated with a caller. The computing device creates a call record based on the authenticating information. The computing device retrieves additional information associated with the caller. The computing device updates the call record based on the additional information. The computing device retrieves a digital signature associated with the caller. The computing device retrieves public key information associated with the caller. The computing device performs a digital signature assessment based on the public key information. The computing device updates the call record based on the digital signature assessment. The computing device adds timestamp information to the call record. The computing device receives a request from a call recipient device. The computing device communicates information based on the call record to the call recipient device. The computing device marks the call record as expired.
    • 在通过数字签名进行呼叫者ID验证的方法中,计算设备接收与呼叫者相关联的认证信息。 计算设备基于认证信息创建呼叫记录。 计算设备检索与呼叫者相关联的附加信息。 计算设备基于附加信息更新呼叫记录。 计算设备检索与呼叫者相关联的数字签名。 计算设备检索与呼叫者相关联的公钥信息。 计算设备基于公开密钥信息执行数字签名评估。 计算设备基于数字签名评估更新呼叫记录。 计算设备向呼叫记录添加时间戳信息。 计算设备从呼叫接收设备接收请求。 计算装置根据呼叫记录将信息传送给呼叫接收装置。 计算设备将呼叫记录标记为已过期。
