Theserecommendations help users discover apps by referring to the experiences of other users. Due to the collection of a large amount of data and user information, there is a problemof insecurity and user’s privacy that are prone to be attacked. To address this issue the blockchain technology can be incorporated to assure cryptographic safety. In this paper,we present a survey of the on-going mobile app recommendations and e-commerce technology trend to address how the blockchain can be incorporated into the collaborativefiltering recommendation systems to enable the users to set up a secured data, which implies the importance of user privacy preference on personalized app recommendations.
