本公开的一个或多个实施例公开了一种基于位置的服务数据处理方法，提高了物联网终端的真实地址的安全性。
参见图1，根据一示例性实施例示出的一种基于位置的服务数据处理方法的流程图，如图1所示，包括：
S101：接收物联网终端发送的位置服务请求；其中，所述位置服务请求包括所述物联网终端的真实地址、位置信息、位置服务请求类型和位置服务提供方；
本实施例的执行主体为区块链，其位于物联网终端与位置服务提供方之间，实现物联网终端与位置服务提供方之间的通信。本实施例中的物联网终端可以包括手机、汽车等，位置服务方可以包括如IOS、Android等操作系统，在此不进行具体限定。本实施例中的区块链包括位置服务提供方对应的服务节点，区块链通过该服务节点与对应的位置服务提供方进行通信，服务节点采用最小化存储方式，仅存储与对应的位置服务提供方相关的位置服务信息。区块链还包括监管部门对应的监管节点，监管节点采用 全量存储方式，存储所有位置服务信息，实现了监管部门对位置提供方提供的位置服务的有效监管，确保了基于位置的服务的合规性。
在具体实施中，物联网终端向区块链发送位置服务请求，其中包括物联网设备的真实地址、位置信息、位置服务请求类型和位置服务提供方，当然还可以包括其他内容，本实施例不进行具体限定。物联网设备的真实地址例如物联网设备的真实IP(中文全称：网际互连协议，英文全称：Internet Protocol)地址、真实Mac(中文全称：媒体存取控制位，英文全称：Media Access Control)地址，位置服务请求类型例如位置信息对应的天气信息，即该位置服务请求用于请求物联网终端的位置信息对应的天气信息。
可以理解的是，在本步骤之后，还可以将位置服务请求发送至监管节点进行存储，即监管节点存储的位置服务信息包括终端设备发送的位置服务请求。
S102：利用智能合约将所述位置服务请求中所述物联网终端的真实地址替换为临时地址，并将替换后的位置服务请求发送至所述位置服务提供方；
在本步骤中，区块链将物联网终端发送的位置服务请求上链，并利用智能合约自动将其中的真实地址替换为临时地址。进一步的，区块链采用链外监听机制，通过对应的服务节点将替换后的位置服务请求发送至位置服务请求中的位置服务提供方，其中包括物联网设备的临时地址、位置信息、位置服务请求类型和位置服务提供方，当然还可以包括其他内容，本实施例不进行具体限定。
S103：接收所述位置服务提供方发送的位置服务响应；其中，所述位置服务响应包括所述临时地址、所述位置服务提供方基于所述位置信息和所述位置服务请求类型生成的响应信息；
在具体实施中，位置服务提供方接收区块链通过对应的服务节点发送的位置服务请求，基于其中的位置信息和位置服务类型生成响应信息，例如，位置信息对应的天气信息为零下12摄氏度。位置服务提供方通过对应的服务节点向区块链返回位置服务响应，即区块链通过对应的服务节点接 收位置服务提供方发送的位置服务响应，其中包括物联网设备的临时地址和上述响应信息。
可以理解的是，在本步骤之后，还可以将位置服务响应发送至监管节点进行存储，即监管节点存储的位置服务信息包括位置服务提供方返回的位置服务响应。
S104：利用所述智能合约将所述位置服务响应中的所述临时地址替换为所述真实地址，并将替换后的位置服务响应发送至所述物联网终端。
在本步骤中，区块链将位置服务提供方返回的位置服务响应上链，并利用智能合约自动将其中的临时地址替换为真实地址。进一步的，区块链通过链外监听机制，向真实地址对应的物联网终端返回替换后的位置服务响应，其中包括物联网设备的真实地址和上述响应信息。物联网终端接收到替换后的位置服务响应后，面向使用者进行信息展示和服务提供。
本申请实施例提供的基于位置的服务数据处理方法，利用区块链实现了物联网终端与位置服务提供方之间的通信。具体的，物联网终端向区块链发送位置服务请求，区块链利用智能合约将其中的物联网终端的真实地址替换为临时地址，并将替换后的位置服务请求发送至位置服务提供方。位置服务提供方基于位置服务请求中的位置信息和位置服务请求类型生成的响应信息，向区块链返回位置服务响应。区块链利用智能合约将其中的物联网终端的临时地址重新替换为真实地址，并将替换后的位置服务响应返回至物联网终端。由此可见，本申请实施例提供的基于位置的服务数据处理方法，通过区块链中的智能合约实现物联网终端的真实地址的替换，从而起到隔离位置服务提供方获取物联网终端的真实地址的作用，保护物联网终端的真实地址不被位置服务提供方获取的前提下，仍能完成基于位置的服务，实现位置服务响应的返回。
本申请实施例公开了一种基于位置的服务数据处理方法，相对于上一实施例，本实施例对技术方案作了进一步的说明和优化。具体的：
参见图2，根据一示例性实施例示出的另一种基于位置的服务数据处理方法的流程图，如图2所示，包括：
S201：接收物联网终端发送的位置服务请求；其中，所述位置服务请求包括所述物联网终端的真实地址、位置信息、位置服务请求类型和位置服务提供方；
S202：利用所述智能合约在链上地址池中选择临时地址，将所述位置服务请求中所述物联网终端的真实地址替换为所述临时地址；
S203：在所述智能合约中记录所述真实地址与所述临时地址的对应关系；
本实施例通过链上地址池维护临时地址，当区块链接收到物联网终端发送的位置服务请求时，随机在链上地址池中选择一个临时地址，用于替换该位置服务请求中的真实地址，并在智能合约中记录上述真实地址和临时地址的对应关系。
S204：将替换后的位置服务请求发送至所述位置服务提供方；
S205：接收所述位置服务提供方发送的位置服务响应；其中，所述位置服务响应包括所述临时地址、所述位置服务提供方基于所述位置信息和所述位置服务请求类型生成的响应信息；
S206：基于所述智能合约中记录的对应关系将所述位置服务响应中的所述临时地址替换为所述真实地址；
在具体实施中，当区块链接收到位置服务提供方返回的位置服务响应时，基于智能合约中记录的对应关系将位置服务响应中的临时地址替换为对应的真实地址。
S207：将替换后的位置服务响应发送至所述物联网终端。
在本实施例的基础上，作为一种可行的实施方式，所述利用所述智能合约在链上地址池中选择临时地址，将所述位置服务请求中所述物联网终端的真实地址替换为所述临时地址，包括：利用所述智能合约在链上地址池中选择状态为未使用的临时地址；将所述位置服务请求中所述物联网终端的真实地址替换为所述临时地址；将所述临时地址的状态更新为使用中；相应的，所述基于所述智能合约中记录的对应关系将所述位置服务响应中的所述临时地址替换为所述真实地址之后，还包括：将所述临时地址的状态更新为未使用。
在本实施方式中，链上地址池包括所有临时地址，每个临时地址对应一个状态，包括使用中和未使用。当区块链接收到物联网终端发送的位置服务请求时，随机在链上地址池中选择一个状态为未使用的临时地址，将位置服务请求中物联网终端的真实地址替换为该临时地址后，将智能合约中该临时地址的状态由未使用更新为使用中。当区块链接收到位置服务提供方返回的位置服务响应时，基于智能合约中记录的对应关系将位置服务响应中的临时地址替换为对应的真实地址后，将该临时地址的状态由使用中更新为未使用。
在本实施例的基础上，作为一种可行的实施方式，将所述位置服务请求中所述物联网终端的真实地址替换为所述临时地址之后，还包括：将所述临时地址从所述链上地址池中删除；相应的，所述基于所述智能合约中记录的对应关系将所述位置服务响应中的所述临时地址替换为所述真实地址之后，还包括：将所述临时地址重新加入所述链上地址池。
在本实施方式中，链上地址池仅包括未使用的临时地址。当区块链接收到物联网终端发送的位置服务请求时，随机在链上地址池中选择一个临时地址，将位置服务请求中物联网终端的真实地址替换为该临时地址后，将该临时地址从链上地址池中删除。当区块链接收到位置服务提供方返回的位置服务响应时，基于智能合约中记录的对应关系将位置服务响应中的临时地址替换为对应的真实地址后，将该临时地址重新加入链上地址池。
由此可见，本实施例通过链上地址池维护临时地址，当区块链接收到物联网终端发送的位置服务请求时，随机在链上地址池中选择一个临时地址，用于替换该位置服务请求中的真实地址。本实施例通过区块链中的智能合约实现物联网终端的真实地址的替换，从而起到隔离位置服务提供方获取物联网终端的真实地址的作用，保护物联网终端的真实地址不被位置服务提供方获取的前提下，仍能完成基于位置的服务，实现位置服务响应的返回。
