Detection method and system of clone terminal devices

Abstract

The invention discloses a detection method and system of clone terminal devices, and the detection is performed on the basis of a network consisting of a front-end server and a certain number of terminal devices. The method comprises the following steps that: S1) the front-end server receives access applications of the terminal devices, performs conversation after key agreement and performs the conversation in a way allowed by different key interval agreements if the access applications of the same terminal devices exist; S2) the front-end server records and stores information of each terminal device and behavior information for communicating with the front-end server; and S3) whether the terminal device is cloned or not is judged by combining the information and behavior information of each terminal device. The detection system has a simple structure, the method is easy to operate, the clone devices can be found timely, the accuracy in clone detection is greatly improved, the clone detection period is shorted, and the detection method and system are conductive to the safety operation of the network and interests of network participants.

Description

technical field [0001] The invention relates to the technical field of communication transmission, mainly to a two-way network content protection system, and in particular to a detection method and system for a cloned terminal device. Background technique [0002] With the development of communication technology, terminal computer users can connect to the Internet through wired or wireless means, and access network resources provided by servers. In order to ensure the security of accessed content, usually the terminal user and the server communicate through a protocol. [0003] In the content protection system, the front-end server sends ciphertext media content to the end user. While obtaining the media content, the end user also needs to obtain the content license of the media content before they can decrypt and watch the media content. In order to realize the secure transmission and authorization control of digital content, a two-way authentication method based on the PK...

Problems solved by technology

[0007] Comparing the above two methods, the former only conducts statistics and detection from a single aspect of the front-end server, and this method can only determine the cloned terminal when the terminal cloning behavior reaches a certain level. The interests of operators and consumers cause a certain degree of damage; although the latter has a small impact on the system and has a certain cost advantage, a single detection method may cause legitimate terminals to be locked by mistake
