3 Architecture of Secure Personalized Recommendation System
As shown in Fig. 1 we provide the deployment of multi-agents technology. In this
system, the client device is a handheld device or PDA as a terminal for receiving
information from a web server and received signal from the GPS satellite. The
detailed explanation of each module can be found in [9], [7].
In this paper, we will focus on to build the secure personalized recommendation
system by applying modified RPCF algorithm for detection profile injection attacks
(push attack or nuke attack) which is highlighted in interface module of Fig. 1.
The users are required to define their preferences (interests) as user profiles. The
user's information can be changed whenever the users want to revise their interests.
On receiving the user request, the personalization agent performs the task of gathering
user information, interest or preferences explicitly and stores the context of
information as the user profiles.
The next step is to analyze the information and apply modified RPCF algorithm.
We picked the significant weighting and trust weighting complements to the RPCF
Algorithm, which can give the secure personalized recommendations to the users.

3.1 Modified RPCF Algorithm
In this sub-section, we will promote RPCF algorithm with significant weighting and
trust weighting to give the accurate recommendation for building secure personalized
recommendation system. The main focus of this paper is to detect the profile injection
attacks by applying modified RPCF algorithm as shown in Fig. 2.
