Abstract

The interest in the blockchain technology has been increasing since its inception and it has been applied to many fields and sectors. The blockchain technology creates a decentralized environment where no third party controls the data and transaction. Mobile apps recommendation has been extensively used to recommend apps to mobile users. For example, Android-based recommendation applications have been developed to recommend other mobile apps for download depending on user's preferences and mobile context. These recommendations 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 problem of 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 collaborative filtering recommendation systems to enable the users to set up a secured data, which implies the importance of user privacy preference on personalized app recommendations.

블록체인기술에 대한 관심은 지속적으로 증가되고 많은 분야에 활용되고 있다. 블록체인기술은 타인이 함부로 데이터와 거래를 제어할 수 없게 하는 분산 환경을 제공한다. 모바일앱 추천은 모바일 사용자에게 적당한 앱을 추천하는데 사용된다. 예를 들어, 사용자의 선호도 및 모바일 환경에 따라 서로 다른 모바일앱을 추천하는 복수의 안드로이드기반 추천앱이 개발되어왔다. 앱 추천은 사용자가 다른 사용자의 경험을 참조하여 앱을 발견하는 데 도움을 준다. 수집된 많은 양의 데이터 및 사용자 정보는 외부 공격에 대한 취약성과 사용자 개인 정보 보호 문제를 내포한다. 이 문제를 해결하는 방법으로 암호화 안전을 보장하는 블록체인 기술을 적용할 수 있다. 본 서베이 논문에서는 모바일앱 추천 기술과 전자상거래 기술 동향을 살펴본다. 개인화된 앱 추천에 대한 사용자의 개인 정보 선호 중요성 측면에서, 블록체인기술과 협업필터링 기술의 접목이 사용자에게 안전한 데이터 환경을 제공할 수 있는지도 살펴본다.
