Embodiment Construction

[0041] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0042] Such as figure 1 with figure 2 As described, a novel privacy protection method for making friends in a nearby mobile social network includes the following steps:

[0043] Step 1: Construct the user's personal attribute preference weight matrix MA l×n ;

[0044]

[0045] Among them, a ij is the element in the user's attribute preference weight matrix, which takes a value of 0 or 1, i∈[1,l], j∈[1,n]; the element of each row in the attribute preference weight matrix represents the user's preference for attributes Degree, also known as attribute weight, n is the number of interest attribute categories, and the elements in each column represent user attributes;

[0046] The interest weight is set according to the percentage of the user's frequency of participating in interest activities within the set time, and the frequency percentage interv...

Abstract

The invention discloses a novel neighbor mobile social network dating privacy protection method. An initiator carries out random matrix and prime number confusion on a personal configuration file matrix MA[l*n] of the initiator himself and gives a confused matrix MA<*>[l*n] to an adjacent respondent who is willing to participate in a neighbor mobile social network in a broadcasting mode; the respondent carries out calculation on a configuration file matrix of himself and the confused matrix MA<*>[l*n] of the initiator, and the respondent is ensured to only know common weight attribute information of two sides; and the respondent sends a matching result to the initiator, the initiator only knows the similar degree of the initiator and the respondent, both the initiator and the respondent do not know any attribute information detail of two sides of the conversation, and the privacy of the initiator and the respondent two sides is protected. In addition, the respondent is used as an agent to forward the personal configuration file of the initiator, and a user more precisely matched with the initiator can be safely found in a wider region.

Description

technical field [0001] The invention relates to the field of computer science and technology, in particular to a method for protecting privacy in the process of making friends in a nearby mobile social network. Background technique [0002] With the increasing popularity of mobile devices (eg, smart phones) and the tremendous development of online social networks, mobile social network services enable friends in the vicinity to better communicate and share each other's interests, hobbies, and the like. Currently mobile social network (MSN) has become an important part of our daily life. [0003] Proximity Mobile Social Networks (PMSNs) are built on top of traditional mobile social network services by embedding (WiFi or Bluetooth interfaces) into smartphones and tablets. It is one of the most emerging social methods in the growth of mobile users. When a mobile user cannot access an online social network on the Internet, for example, due to lack of Internet access to a hotsp...
