通过本申请实施例的方法，可以根据终端或网络设备的类型确认请求，结合网络设备的热点集合，对终端或网络设备请求的无线热点确认其是否需要认证的类型。
在本申请一些实施例中，所述类型确认请求来自终端，且所述类型确认请求包括所述终端扫描到的所述第一无线热点的标识。本实施例的方法还包括以下步骤：响应于所述第一无线热点的类型被识别为需要认证的开放无线热点，向所述终端反馈所述第一无线热点的标识信息以及与该标识信息对应的标签，所述标签用于指示所述第一无线热点的类型为需要认证的开放无线热点。
其中，终端上运行的应用程序可向网络设备发送类型确认请求，该类型确认请求携带第一无线热点的标识，以请求判断任意第一无线热点是否为需要认证的开放无线热点。网络设备根据第一无线热点的标识以及第一无线热点的其他相关信息，例如位置信息、厂商来源字段等，判断第一无线热点与第二无线热点是否相同或相似。当第一无线热点与第二无线热点相同或相似时，第一无线热点即为需要认证的开放无线热点。网络设备向该终端反馈第一无线热点的标识信息以及与该标识信息对应的标签，该标签指示无线热点的类型为需要认证的开放无线热点。在一些实施例中，终端上运行的应用程序向网络设备发送的类型确认请求可以包括终端向网络设备发送的热点信息获取请求，该热点信 息获取请求用于向网络设备请求终端扫描到的无线热点的信息；在一些实施例中，该热点信息获取请求可以包括终端扫描到的无线热点的标识(如SSID)，并用于请求网络设备提供无线热点的类型以及扫描到的无线热点中的加密热点的密码；在一些实施例中，由于终端设备可以区分其扫描到的无线热点为加密热点还是开放热点，但难以区分开放热点是否需要认证，故上述类型确认请求可主要用于请求网络设备反馈开放热点的类型。
在本申请一些实施例中，本实施例的方法在获取所述第一无线热点的信息之前还包括：获取来自终端的、基于该终端对所述第二无线热点的连接操作生成的连接数据；响应于所述连接数据指示连接所述第二无线热点时需要认证，将该所述第二无线热点的类型识别为需要认证的开放无线热点，并将25该第二无线热点添加至所述热点集合中。
在一些实施例中，安装于终端的应用程序，可以检测用户连接无线热点的连接操作生成的连接数据，当发现连接某个无线热点时，产生了例如认证页面等认证数据后，将该无线热点识别为需要认证的开放无线热点，即第二无线热点，并将识别结果上报给网络设备，以供网络设备将该第二无线热点的信息添加至热点集合中。在一些实施例中，应用程序可通过终端将对所述第二无线热点的连接操作生成的连接数据发送给网络设备，网络设备响应于所述连接数据指示连接所述第二无线热点时需要认证，将该所述第二无线热点的类型识别为需要认证的开放无线热点，并将该第二无线热点添加至所述热点集合中。
具体地，所述第一无线热点或所述第二无线热点的信息包括以下至少一项：所述第一无线热点或所述第二无线热点的标识；所述第一无线热点或所述第二无线热点的位置信息；所述第一无线热点或所述第二无线热点的厂商来源字段。在一些实施例中，标识可包括SSID(Service Set Identifier，服务集标识)；位置信息可包括地理位置哈希编码(geohash)；厂商来源字段可包括BSSID(Basic Service Set Identifier，基本服务集标识)的前六位。
相应地，在本申请一些实施例中，与所述第一无线热点相似的第二无线热点包括：与所述第一无线热点的标识相同并且与所述第一无线热点的厂商来源字段相同或相似的第二无线热点；或者，与所述第一无线热点的标识相同并且所述位置信息指示与所述第一无线热点在同一区域内的第二无线热点；或者， 与所述第一无线热点的标识相似并且所述位置信息指示与所述第一无线热点在同一区域内的第二无线热点。
在一些实施例中，当第二无线热点与第一无线热点的标识相同并且厂商来源字段相同或相似时，可判定第二无线热点与第一无线热点相似。例如，类型确认请求包含第一无线热点的SSID和BSSID，网络设备查询预设的热点集合中第二无线热点的SSID和BSSID，当第二无线热点与第一无线热点的SSID相同并且BSSID前六位相同时，判定第二无线热点与第一无线热点相似。
在一些实施例中，当第二无线热点与第一无线热点的标识相同并且位置信息指示在同一区域内时，可判定第二无线热点与第一无线热点相似。例如，类型确认请求包含第一无线热点的SSID和位置信息，网络设备查询预设的热点集合中第二无线热点的SSID和位置信息，当第二无线热点与第一无线热点的SSID相同并且第二无线热点与第一无线热点的位置信息指示在同一区域内时，判定第二无线热点与第一无线热点相似。
在一些实施例中，当第二无线热点与第一无线热点的标识相似并且位置信息指示在同一区域内时，可判定第二无线热点与第一无线热点相似。例如，类型确认请求包含第一无线热点的SSID和位置信息，网络设备查询预设的热点集合中第二无线热点的SSID和位置信息，当第二无线热点与第一无线热点的SSID相似并且第二无线热点与第一无线热点的位置信息指示在同一区域内时，判定第二无线热点与第一无线热点相似。
在本申请一些实施例中，所述位置信息包括地理位置的哈希编码，所述位置信息指示与所述第一无线热点在同一区域内包括：所述第一无线热点与所述第二无线热点的地理位置哈希编码具有相同的区域字段。
例如，通过geohash算法将无线热点的纬度和经度分别转换为哈希编码(geohash)，字符串相似的表示距离相近，可以利用字符串的前缀匹配来确定若干无线热点之间的距离。geohash编码的长度可以决定距离精度，例如，当geohash base32编码长度为8时，精度在19米左右，而当geohash base32编码长度为9时，精度在2米左右。编码长度可以根据数据情况进行选择。
例如地球纬度区间是[-90，90]，设中心点纬度是39.928167，可以通过下面算法对纬度39.928167进行逼近编码：
1)区间[-90，90]进行二分为[-90，0)，[0，90]，称为左右区间，可以确定39.928167属于右区间[0，90]，给标记为1；
2)接着将区间[0，90]进行二分为[0，45)，[45，90]，可以确定39.928167属于左区间[0，45)，给标记为0；
3)递归上述过程39.928167总是属于某个区间[a，b]，随着每次迭代区间[a，b]总在缩小，并越来越逼近39.928167；
4)如果给定的纬度x(39.928167)属于左区间，则记录0，如果属于右区间则记录1，这样随着算法的进行会产生一个序列1011100，序列的长度跟给定的区间划分次数有关。
同理，地球经度区间是[-180，180]，可以对中心点经度116.389550进行编码。
通过上述计算，纬度产生的编码为10111 00011，经度产生的编码为1101001011。偶数位放经度，奇数位放纬度，把2串编码组合生成新串：11100 11101 00100 01111。
最后使用用0-9、b-z(去掉a，i，1，o)这32个字母进行base32编码，首先将11100 11101 00100 01111转成十进制，对应着28、29、4、15，十进制对应的编码就是wx4g，作为中心点的geohash编码。
同理，第二无线热点和第一无线热点也可分别计算其geohash编码，例如，第二无线热点和第一无线热点的geohash编码分别为8位，可以设中心点的geohash编码前6位为区域字段。如果第二无线热点和第一无线热点的地理位置哈希编码前6位，即区域字段相同，即表明第二无线热点和第一无线热点在同一区域内。区域字段的长度可以根据实际精度需要自由设定。
在本申请一些实施例中，所述第二无线热点与所述第一无线热点的标识相似包括：所述第一无线热点的标识与所述第二无线热点的标识的编辑距离在预设相似度阈值内。
其中，编辑距离(Edit Distance)，又称Levenshtein距离，是指两个字串之间，由一个转成另一个所需的最少编辑操作次数。许可的编辑操作包括将一个字符替换成另一个字符，***一个字符，删除一个字符。例如，要计算cafe和coffee的编辑距离可根据cafe→caffe→coffe→coffee的顺序进行计算。一般来 说，编辑距离越小，两个串的相似度越大。
例如，对于两个字符串str1和str2，设第二无线热点SSID为str1，第一无线热点SSID为str02。生成如下矩阵：
    s t r 0 2
  0 1 2 3 4 5
s 1          
t 2          
r 3          
l 4         D[n，m]
根据公式(1)计算矩阵中每个单元的值：
d[i，5j]＝min(d[i-1，j]+1、d[i，j-1]+1、d[i-1，j-1]+temp)..................(1)；
其中，当str1[i]＝＝str2[j]时，temp＝0；否则，temp＝1。i、j为自然数且i≥2，j≥2。d[i-1，j]+1表示增加操作，d[i，j-1]+1表示删除操作，d[i-1，j-1]+temp表示替换操作。
编辑距离可根据公式(2)计算得到：
编辑距离＝1-D[n，m]/max(str1字符串长度，str2字符串长度)......(2)；
其中，D[n，m]为编辑距离计算矩阵的最后一位。
利用编辑距离算法对第二无线热点SSID与第一无线热点SSID进行计算，得到其编辑距离。通过预设相似度阈值对两个SSID相似度进行筛选，当编辑距离在预设相似度阈值之内时，确定第二无线热点与所述第一无线热点的SSID相似。如果第二无线热点与所述第一无线热点还在同一区域内时，可基本判定第二无线热点与所述第一无线热点相似。
在本申请一些实施例中，前述响应于所述连接数据指示连接所述第二无线热点时需要认证，将该所述第二无线热点的类型识别为需要认证的开放无线热点，并将该第二无线热点添加至所述热点集合中的步骤，包括：
响应于所述连接数据指示连接所述第二无线热点时需要认证且该连接认证数据指示的连接时间在预设时间阈值之内，将该所述第二无线热点的类型识 别为需要认证的开放无线热点，并将该第二无线热点添加至所述热点集合中。
在一些实施例中，当网络设备收集来自终端设备的无线热点的连接数据时，可生成数据列表；该数据列表可包含无线热点标识、无线热点需要认证的信息、以及连接时间。通过设置预设时间阈值，仅对在预设时间阈值之内产生的连接数据的无线热点添加认证无线热点标签，可筛选出最近一段时间内产生认证情况的开放无线热点，以排除过期的数据，保持数据的鲜活性。
在本申请一些实施例中，该方法在将该第一无线热点的类型识别为需要认证的开放无线热点之后，还包括可包括以下步骤：响应于获取到来自终端的、基于该终端对所述第一无线热点的连接操作生成的连接数据，更新所述第一无线热点的类型；其中，所述连接数据用于指示连接所述第一无线热点时需要提供密码、或者用于指示连接所述第一无线热点时需要进行认证、或者用于指示允许直接连接所述第一无线热点，所述第一无线热点的类型包括需要提供密码的加密无线热点、需要认证的开放无线热点或者无需认证的开放无线热点。
通过上述实施例，可以根据实际产生的连接数据，更新第一无线热点的类型，以对被错误识别或发生变化的无线热点的类型进行纠错。例如，收集来自于终端的因连接第一无线热点而产生的连接数据，基于连接数据对第一无线热点的类型进行识别。例如，基于对连接数据分析确定连接第一无线热点需要提供密码，则将该第一无线热点识别为需要提供密码的加密无线热点，并相应更新该第一无线热点的类型。或者，基于对连接数据分析确定该第一无线热点无需认证或密码即可直接连接，则将该无线热点识别为无需认证的开放无线热点，并相应更新该第一无线热点的类型。又如，基于对连接数据分析确定连接该第一无线热点需要认证的，则将该第一无线热点识别为需认证的开放无线热点，并将该第一无线热点作为第二无线热点，加入热点集合中。通过上述步骤，就可将错误标记为需认证的开放无线热点的情况改正。
此外，对于无线热点类型发生实际变化的情况，例如，原有不需要身份认证的无线热点变为加密无线热点，也可根据上述方法更新无线热点类型。
根据本申请的另一个方面，提供一种计算机可读存储介质，所述计算机可读存储介质存储指令，所述指令根据本申请所述的方法进行执行。
