中新网南京8月31日电(孟祥磊)“360和百度的搜索战”打得正酣，一段记者采访360总裁周鸿祎的视频在网上流传开来。30日，南京大学学生刘靖康突发奇想，利用视频中记者采访时的拨号声音还原出了手机号码。31日，周鸿祎在微博上称确有其事，并开玩笑说“已经接到几十个骚扰电话”。李开复更在微博中伸出“橄榄枝”，称“希望两周后在南京见面”。

　　从视频的第33秒到43秒，可以清晰地听到记者给周鸿祎拨号的整个过程，用人耳听会觉得每个音都差不多，但是将它们转化成图形以后，就可以很清楚地看到它们的差别。刘靖康介绍说：“我们平常所用的电话，是通过DTMF信号来向交换机传递命令的，我们每按下电话键盘上的一个键，就会同时发出两个不同频率的声音，转化成电流在对面解析。通过某些相关软件手段便可以还原号码按键音，进而解析出号码。”

　　刘靖康通过相关软件做出了记者采访周鸿祎时按键音的声谱，对照每个号码按键声音的标准音，于是就还原出了360总裁周鸿祎的号码。这样一篇帖子很快引起了广大网友的好奇心，不到12小时已经超过2万的浏览量，而且不少人雀雀欲试，希望可以破译出周鸿祎的号码，据周鸿祎的新浪微博称：“这位同学确实能干，各位就不用验证了，也请大家别在晚上十一点后打电话，谁也不希望刚睡着就被突然的电话铃声惊醒吧，今晚已经有几十个好奇的电话了。”

　　刘靖康现就读于南京大学软件工程专业，此前因盗用7000张图片做出南京大学各院系“平均脸”，进而引发了一阵高校“平均脸”的小热潮，这次通过按键音破译手机号码用他的话说只是“突发奇想”。这位“电脑达人”的一次次“突发奇想”都有不少惊喜，高中时在全国中小学生电脑制作大赛中的“突发奇想”使他获奖的20分加分而进入南大学习。

　　关于此次通过按键音破译出手机号码，刘靖康在最后特别提醒：“电视以及有声媒体要注意拨给公众人物的时候，不要把拨号过程也放出来。我们平常用手机拨号，或者在门禁处或者一些机器上输入密码的时候，千万要注意身旁有没有人录音，否则很容易被还原出来，造成信息泄露，甚至财产安全。”(完)
