Embodiment Construction

[0045] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0046] see Figure 1a , Figure 1b , a clone-detectable license management method for a front-end system, comprising:

[0047] S1. The terminal sends account opening information to apply for account opening, the terminal where the portal site is located and the front-end server send the user name and verification code, and each generate a verification key; specifically:

[0048] (1) The terminal user sends terminal characteristic information such as MAC address to the portal website;

[0049] (2) The portal sets a uniquely identified user name and verification code for the end user;

[0050] (3) The terminal saves the user name and verification code;

[0051] (4) The portal sends the user name and verification code of the terminal to the f

Abstract

The invention discloses a license management method capable of detecting clone for a front-end system. The method comprises the following steps of: 1, sending an account establishing information by a terminal, applying for establishing an account, sending a user name and a verification code by a portal website to the terminal and a front-end server, and respectively generating verification keys; 2, generating a public and private key pair by the terminal, and sending a public key to the front-end server; 3, judging whether a session key exists in a memory of the terminal, if no session key exist in the memory, entering the step 4, otherwise, entering the step 5; 4, communicating by using a temporary key randomly generated by the terminal so as to apply for a content license; and 5, communicating by using the session key so as to apply for the content license. The invention also discloses a license management device capable of detecting the clone for the front-end system. According to the invention, the safety of communication between a client and a digital rights management server is improved; and a terminal clone phenomenon can be detected.
