本发明的实施方式
本申请实施例应用于由各个终端设备组成的区块链系统中,所述区块链系统用于对医疗记录进行存储和管理,每个终端设备均作为所述区块链系统的一个节点。图1所示为即为所述区块链系统的示意图,各个医疗机构及个人用户均可在该系统中进行注册。当医疗机构或者个人用户在该系统中进行注册时,首先通过手机、平板电脑、或者台式机等终端设备向服务器发送注册请求,在该注册请求中可以包括但不限于注册类型,身份标识及相关证明文件等等。
其中,注册类型可以分为医疗机构注册及个人用户注册两种,对于医疗机构而言,身份标识可以为该医疗机构的营业执照号码或者工商管理登记号码等等,相关证明文件可以为该医疗机构的营业执照扫描件或者工商管理登记扫描件等等,对于个人用户而言,身份标识可以为该用户的身份证号码或者医保卡号码等等,相关证明文件可以为该用户的身份证扫描件或者医保卡扫描件等等。经后台核对无误后,服务器会为注册者分配身份证书(可分为机构身份证书及个人身份证书两种)及密钥。在注册完成之后,医疗机构或个人用户所使用的终端设备即成为所述区块链系统的一个节点。
医疗机构的医疗人员在对患者进行过诊断(包括但不限于B超、CT、X线或者核磁共振等检测项目)后,可以通过医疗机构指定的终端设备(所述区块链系统中的一个节点)将相应的医疗记录(包括但不限于患者基本信息、医疗胶片以及报告等)上传至服务器中,服务器将其存储至所述区块链系统中以保证其安全性,杜绝其被篡改的可能性。当医疗记录被存储至所述区块链系统中之后,只有上传材料的医疗机构以及患者本人才有权限对其进行查看。
现以患者本人的查看医疗记录的过程为例进行说明:患者通过其终端设备(所述区块链系统中的一个节点)向服务器发起医疗记录查看请求,在该医疗记录查看请求中携带了其个人身份证书以及密钥签名,服务器在接收到该医疗记录查看请求后,对其中的个人身份证书以及密钥签名进行验证,若验证成功,则对其开放区块链访问服务接口,患者的终端设备可以通过调用该区块链访问服务接口读取存储在所述区块链系统中本人的医疗记录,并展示给患者查看。
医疗机构的查看过程与之类似,但需要注意的是,一般在一个医疗机构中可能会有众多的医疗人员,但不是所有人都有权限查看该患者的医疗记录,因此,当医疗人员通过医疗机构指定的终端设备以该医疗机构的名义去查看医疗记录时,医疗机构的终端设备会首先对其权限进行确认,例如,可以通过该医疗人员登录终端设备时使用的账号来确认该医疗人员的身份,并通过查询权限表来确定其是否有查看该患者医疗记录的权限。
当医疗机构的终端设备确认当前医疗人员具有查看该患者医疗记录的权限时,即向服务器发起医疗记录查看请求,在该医疗记录查看请求中携带了其机构身份证书以及密钥签名,服务器在接收到该医疗记录查看请求后,对其中的机构身份证书以及密钥签名进行验证,若验证成功,则对其开放区块链访问服务接口,医疗机构的终端设备可以通过调用该区块链访问服务接口读取存储在所述区块链系统中该患者的医疗记录,并展示给当前医疗人员查看。
进一步地,患者还具有将医疗记录的查看权限授权给其它的医疗机构或者个人用户,其中,在授权给医疗机构时,既可以授权给整个医疗机构,也可以仅授权给该医疗机构中的一个或几个具体医疗人员。
现以患者将医疗记录的查看权限授权给其它医疗机构的某一具体医疗人员为例进行详细说明:
1、患者A在授权链上发起一个授权请求,将某报告或一段时间内的报告授权给医疗机构H中的医生B。在该授权请求中携带了其个人身份证书以及密钥签名,服务器在接收到该授权请求后,对其中的个人身份证书以及密钥签名进行验证,若验证成功,则为医疗机构H添加查看权限,并向医疗机构H的终端设备发送这一授权通知,医疗机构H的终端设备在接收到授权通知后,将该授权添加入前述授权表中。
2、医生B登录医疗机构H的终端设备,请求查看患者A的医疗记录,医疗机构H的终端设备查询权限表来确定其是否有查看患者A医疗记录的权限,若查询到医生B具有查看患者A医疗记录的权限,则发送通知至服务器。
3、服务器在授权链中查询相应的授权记录,若查询到授权记录,则反馈查询成功的消息至医疗机构H的终端设备。
4、医疗机构H的终端设备向服务器发起医疗记录查看请求,在该医疗记录查看请求中携带了其机构身份证书以及密钥签名,服务器在接收到该医疗记录查看请求后,对其中的机构身份证书以及密钥签名进行验证,若验证成功,则对其开放区块链访问服务接口,医疗机构H的终端设备可以通过调用该区块链访问服务接口读取存储在所述区块链系统中患者A的医疗记录。
5、医疗机构H的终端设备对读取的医疗记录进行解析,并将最终结果展示给医生B查看。
患者将医疗记录的查看权限授权给其它个人用户的过程与之类似,此处不再赘述。
患者还可以随时通过在授权链上发起取消授权请求,对之前的授权进行取消操作,授权取消后,之前被授权的医疗机构或者个人用户将无法查看到患者的医疗记录。
针对以上所述的区块链系统,本申请实施例提供了一种采用层级的授权模式的医疗记录权限管理方法,医疗记录所属的患者本人拥有最高的授权层级,其使用的终端设备作为整个授权体系的一级节点,一级节点可以对其它用户及医疗机构进行授权,得到一级节点授权的用户及医疗机构作为整个授权体系的二级节点。其中,一级节点在对二级节点进行授权时,可以对授权等级进行选择,在本实施例中提供了两类授权模式,第一类授权为完全授权,得到授权的用户及医疗机构拥有第一权限等级,不仅可以查看上述医疗记录,还可以进一步对其它用户及医疗机构进行授权,第二类授权为部分授权,得到授权的用户及医疗机构拥有第二权限等级,可以查看上述医疗记录,但无法继续对其它用户及医疗机构进行授权,得到二级节点授权的用户及医疗机构作为整个授权体系的三级节点。其中,二级节点在对三级节点进行授权时,也可以继续对授权等级进行选择,具体的授权方式与上述内容类似,此处不再赘述。不断重复以上的上一级节点对下一级节点的授权过程,最终可以形成如图2所示的树状授权信息,所述树状授权信息中记录了各个节点之间的授权层级关系,以及各个节点的权限等级,其中,使用圆形表示的节点为得到第一权限等级的节点,使用方形表示的节点为得到第二权限等级的节点。
如图3所示,所述医疗记录权限管理方法具体可以包括以下所述的一个节点对另一个节点进行授权的过程:
步骤S301、接收第一节点发送的授权请求。
所述授权请求中包括医疗记录标识、所述第一节点的身份标识、第二节点的身份标识以及所述第二节点的权限等级,所述第一节点为所述区块链系统中的任意一个节点,所述第二节点为所述区块链系统中除所述第一节点之外的任意一个节点。
步骤S302、在预设的权限信息记录中确定与所述医疗记录标识对应的树状授权信息。
在所述权限信息记录中存储着与各个医疗记录标识对应的树状授权信息,每个医疗记录标识均有唯一的树状授权信息与之对应,根据所述授权请求中包括的医疗记录标识即可在所述权限信息记录中确定与其对应的树状授权信息。
步骤S303、根据所述第一节点的身份标识在所述树状授权信息中查询所述第一节点的权限等级。
若所述第一节点的权限等级为第一权限等级,则执行步骤S304,若所述第一节点的权限等级为第二权限等级,则执行步骤S305。
所述第一权限等级为查看目标医疗记录以及授权其它节点查看所述目标医疗记录的权限等级,所述第二权限等级为查看所述目标医疗记录的权限等级,所述目标医疗记录为在所述区块链系统中存储的与所述医疗记录标识对应的医疗记录。
步骤S304、将所述第二节点的身份标识以及第二节点的权限等级添加入所述树状授权信息中,并将所述第二节点作为所述第一节点的子节点。
若所述第一节点的权限等级为第一权限等级,则其可以进一步授权其它节点查看所述目标医疗记录,因此其授权请求将得到服务器的认可,服务器会将所述第二节点的身份标识以及第二节点的权限等级添加入所述树状授权信息中,并将所述第二节点作为所述第一节点的子节点,此时,所述第二节点也具有了对应的权限等级。
步骤S305、向所述第一节点发送授权失败消息。
若所述第一节点的权限等级为第二权限等级,则其并没有进一步授权其它节点查看所述目标医疗记录的权限,因此其授权请求将被服务器拒绝,服务器将会向其发送授权失败消息,告知其并不具备进一步授权其它节点查看所述目标医疗记录的权限。
进一步地,上级的父节点可以随时对其各级子节点取消授权。如图4所示,所述医疗记录权限管理方法还可以包括以下所述的一个节点对另一个节点进行取消授权的过程:
步骤S401、接收所述第一节点发送的取消授权请求。
所述取消授权请求中包括所述医疗记录标识、所述第一节点的身份标识以及所述第二节点的身份标识。
步骤S402、在所述权限信息记录中确定与所述医疗记录标识对应的树状授权信息。
步骤S402的过程与步骤S302的过程类似,具体过程可参照前述内容,此处不再赘述。
步骤S403、根据所述树状授权信息判断所述第二节点是否为所述第一节点的子节点。
若所述第二节点为所述第一节点的子节点,则执行步骤S404,若所述第二节点不是所述第一节点的子节点,则执行步骤S405。
步骤S404、将所述第二节点以及所述第二节点的各个子节点从所述树状授权信息中删除。
若所述第二节点为所述第一节点的子节点,则所述第一节点可以取消对所述第二节点的授权,因此其取消授权请求将得到服务器的认可,服务器会将所述第二节点以及所述第二节点的各个子节点从所述树状授权信息中删除,此时,所述第二节点以及所述第二节点的各个子节点将不再具有对应的权限等级,无法查看所述目标医疗记录。
如图2所示,若节点1取消对节点3的授权,则节点3及其下的各级子节点均丧失对医疗记录的查看权限,也即节点3及其下的各级子节点将从该授权树状结构中被删除,结果如图5所示。
步骤S405、向所述第一节点发送取消授权失败消息。
若所述第二节点不是所述第一节点的子节点,则所述第一节点无法取消对所述第二节点的授权,因此其取消授权请求会被服务器拒绝,服务器将会向其发送取消授权失败消息,告知其并不具备取消所述第二节点的授权的权限。此时,所述第二节点仍然具有原有的权限等级。进一步地,上级的父节点可以随时对其各级子节点修改授权。如图6所示,所述医疗记录权限管理方法还可以包括以下所述的一个节点对另一个节点进行修改授权的过程:
步骤S601、接收所述第一节点发送的修改授权请求。
所述修改授权请求中包括所述医疗记录标识、所述第一节点的身份标识、所述第二节点的身份标识以及授权修改类型。
步骤S602、在所述权限信息记录中确定与所述医疗记录标识对应的树状授权信息。
步骤S602的过程与步骤S302的过程类似,具体过程可参照前述内容,此处不再赘述。
步骤S603、根据所述树状授权信息判断所述第二节点是否为所述第一节点的子节点。
若所述第二节点为所述第一节点的子节点,则执行步骤S604,若所述第二节点不是所述第一节点的子节点,则执行步骤S605。
步骤S604、按照所述授权修改类型对所述第二节点的权限等级进行修改。
若所述第二节点为所述第一节点的子节点,则所述第一节点可以修改对所述第二节点的授权,因此其修改授权请求将得到服务器的认可,服务器将按照所述授权修改类型对所述第二节点的权限等级进行修改。
具体地,若所述授权修改类型为第一修改类型,则将所述第二节点的权限等级修改为所述第一权限等级;若所述授权修改类型为第二修改类型,则将所述第二节点的各个子节点从所述树状授权信息中删除,并将所述第二节点的权限等级修改为所述第二权限等级。
如图2所示,若节点1更改对节点3的授权,将对节点3的第一权限等级修改为第二权限等级,则节点3仍然具有对医疗记录的查看权限,但无法继续对其它用户及医疗机构进行授权,其下的各级子节点均丧失对医疗记录的查看权限,也即节点3其下的各级子节点将从该授权树状结构中被删除,结果如图7所示。
步骤S605、向所述第一节点发送修改授权失败消息。
若所述第二节点不是所述第一节点的子节点,则所述第一节点无法修改对所述第二节点的授权,因此其修改授权请求会被服务器拒绝,服务器将会向其发送修改授权失败消息,告知其并不具备修改所述第二节点的授权的权限。此时,所述第二节点仍然具有原有的权限等级。特殊地,当出现授权冲突的情况时,以最高层级的节点的授权为准。如图8所示,所述医疗记录权限管理方法还可以包括以下所述的考虑授权冲突情况的一个节点对另一个节点进行授权的过程:
步骤S801、接收第一节点发送的授权请求。
步骤S802、在预设的权限信息记录中确定与所述医疗记录标识对应的树状授权信息。
步骤S803、根据所述第一节点的身份标识在所述树状授权信息中查询所述第一节点的权限等级。
步骤S801至步骤S803的过程与步骤S301至步骤S303的过程类似,具体过程可参照前述内容,此处不再赘述。
若所述第一节点的权限等级为第一权限等级,则执行步骤S804及其后续步骤,若所述第一节点的权限等级为第二权限等级,则执行步骤S807。
步骤S804、判断所述第二节点是否已在所述树状授权信息中。
若所述第二节点已在所述树状授权信息中,则执行步骤S805及其后续步骤,若所述第二节点不在所述树状授权信息中,则执行步骤S806。
步骤S805、根据所述树状授权信息判断所述第一节点的层级是否高于第三节点的层级。
所述第三节点为所述第二节点的父节点。
若所述第一节点的层级高于所述第三节点的层级,则执行步骤S806,若所述第一节点的层级低于或等于所述第三节点的层级,则执行步骤S807。
步骤S806、将所述第二节点变更为所述第一节点的子节点,并按照所述授权请求对所述第二节点的权限等级进行调整。
如图2所示,若节点1又对节点7进行了授权,与节点4对节点7的授权产生了冲突,此时,由于节点1比节点4的层级更高,则以节点1的授权为准,若节点1授权给节点7的是第二权限等级,则节点7仍然具有对上述医疗记录的查看权限,且从三级节点变为了二级节点,但无法继续对其它用户及医疗机构进行授权,节点7其下的各级子节点均丧失对上述医疗记录的查看权限,也即节点7其下的各级子节点将从该授权树状结构中被删除,结果如图9所示。若节点1授权给节点7的是第一权限等级,则节点7仍然具有对上述医疗记录的查看权限,且从三级节点变为了二级节点,且节点7可以继续对其它用户及医疗机构进行授权,节点7其下的各级子节点随其做相应的变更,结果如图10所示。
步骤S807、向所述第一节点发送授权失败消息。
步骤S807的过程与步骤S305的过程类似,具体过程可参照前述内容,此处不再赘述。
综上所述,本申请实施例为每份医疗记录均设立与其对应的树状授权信息,在所述树状授权信息中记录了各个节点之间的授权层级关系,以及各个节点的权限等级,其中,拥有第一权限等级的节点可以查看医疗记录以及授权其它节点查看医疗记录,即既有查看的权限又有授权的权限,而拥有第二权限等级的节点只可以查看医疗记录,即仅有查看的权限而没有授权的权限。拥有授权权限的节点可以根据实际情况将相关权限(第一权限等级或第二权限等级)授予其所信任的其它节点,将新的受信任节点添加入所述树状授权信息中。通过这样的授权层级关系,将医疗记录的公开范围控制在一个由各层信任链构成的有限范围内,在保证患者的隐私不被不法分子获取的前提下将其医疗记录在可控的信任节点间进行共享,从而同时兼顾这些医疗记录的开放性以及私密性。
