Embodiment Construction

[0077] In order to better understand the above-mentioned technical solution, the above-mentioned technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0078] Such as figure 1 As shown, this embodiment provides a mobile streaming media edge cooperative distribution device based on differential privacy, including a data privacy module and a collaborative decision module.

[0079] The data privacy module is deployed in streaming media viewing user terminals and relay transmission user terminals. The data privacy module collects and fuzzes the user information of smart terminals in the mobile edge environment, realizes user data privacy protection, and provides auxiliary data for the collaborative decision-making module. The data privacy module includes two submodules: a geographic location privacy submodule and a collaboration cost privacy submodule; the geographic location privacy submodule is re...

Abstract

The invention belongs to the technical field of mobile edges, and discloses a mobile streaming media edge cooperative distribution device and method based on differential privacy, and the device comprises a data privacy module and a cooperative decision module. When a streaming media cooperative transmission period starts, resource state information of an edge server and request video clip information of a streaming media watching user is collected. fuzzification request information of a streaming media watching user is acquired. A geographic position privacy model is created. Cooperation information of a relay transmission user is acquired. A cooperation cost privacy model and a reward function decision model are established. A collaborative user matching model is created and a streamingmedia content distribution path is determined according to the reward function decision model. Streaming media content edge cooperative distribution is completed, and related information is updated. The problem that in the prior art, the privacy of sensitive data cannot be guaranteed through streaming media cooperative transmission is solved, leakage of user privacy data can be prevented, and thecost of streaming media cooperative distribution is reduced.

Description

technical field [0001] The present invention relates to the field of mobile edge technology, in particular to a device and method for collaborative distribution of mobile streaming media edge based on differential privacy. Background technique [0002] With the explosive growth of the number of mobile devices and the rapid development of wireless communication technology, the global data traffic of mobile networks is increasing exponentially. According to the Cisco Visual Networking Index forecast, global Internet traffic will increase nearly three-fold from 2017 to 2022. In 2017, mobile streaming media traffic accounted for 60% of global Internet traffic, and this proportion is expected to rise to 78% by 2022. The key to the success of mobile streaming media services is to provide users with high-bit rate, low-latency, and distortion-free streaming media content. The explosive growth of streaming media data traffic makes it difficult for the traditional streaming media cont...
