Based on the article from BBC News, Facebook is planning to implement a voice recognition feature into the Facebook mobile app which will automatically detect the music or TV shows that you are watching. Facebook claims that this app will only passively detect music and TV show, however, many people still show their concerns about the new feature might pry into their private conversations.
Apparently, this new Facebook feature is based on the method of mathematically comparing the sound waves. Since any music or TV shows could be pre-installed in the database, it is easy to compare them. However, for common conversations, the specific sentences or words are very spontaneous, it is not possible to effectively capture the contents by any algorithm. The article says that Facebook claim they do not store the recorded detected voice. As long as Facebook keep their promise, this new feature should not be a threat to the user's privacy.
But to the consideration from Facebook, is it really worth to imperiously add this new feature? Privacy protection is probably one of the biggest concern for most users. Any privacy issue regarding to the digital marketing strategy, even throught might or might not be the concern of the company's instrest, will be eventually votted by the user's feet. Today's ripid development of digital marketing is a product from the boom of Internet, but it will graduately grow into a normal and bounded status.
