正好前一陣看了這么一個新聞,17年底的事兒,盡管不能直接回答這個問題,不過...
https://www.nytimes.com/2017/12/28/business/media/alphonso-app-tracking.html
That Game on Your Phone May Be Tracking What You're Watching on TV
Yet these apps, once downloaded onto a smartphone, have the ability to keep tabs on the viewing habits of their users — some of whom may be children — even when the games aren't being played.
It is yet another example of how companies, using devices that many people feel they can't do without, are documenting how audiences in a rapidly changing entertainment landscape are viewing television and commercials.
The apps use software from Alphonso, a start-up that collects TV-viewing data for advertisers. Using a smartphone's microphone, Alphonso's software can detail what people watch by identifying audio signals in TV ads and shows, sometimes even matching that information with the places people visit and the movies they see. The information can then be used to target ads more precisely and to try to analyze things like which ads prompted a person to go to a car dealership.
More than 250 games that use Alphonso software are available in the Google Play store; some are also available in Apple's app store.
大體就是說Alphonso是一家為廣告商提供電視節(jié)目觀看數據的企業(yè),廣告商可以通過用戶的電視節(jié)目觀看習慣來更好地推送廣告
那么它是怎么收集這些數據的呢...
通過用戶的手機話筒來檢測電視里面的聲音
那么它是怎么跑到用戶手機上去的呢
內置在游戲里,而且谷歌商店上已經有超過250個游戲內置了Alphonso的軟件...
當然這家公司宣稱不會收集手機用戶的對話信息,也拒絕公布到底收集了多少數據,只是說用戶可以自己選擇關掉訪問話筒的權限
要放了以前我覺得手機軟件實時監(jiān)聽用戶對話,有點兒陰謀論的感覺...
現在可以完全確認的是
通過話筒監(jiān)聽對話技術上沒有難度
已經有別的公司確實這么做了,而且還是正規(guī)的企業(yè),而且(貌似)還沒因此受到處罰,而且還會繼續(xù)做下去
根據部分答案可以疑似確認的是
手機淘寶在用戶沒有進行語音輸入的時間段使用了話筒
淘寶上推送的商品和用戶日常對話有關聯性
emmm.....這個趨勢太可怕了 |
