System and method for software activation and further tracking of its states on an end-user computing device (computer) was developed to provide software developers a flexible and secure tool for software distribution and gathering statistics of usage of software activation. The method consists of the following logical steps: (a) obtaining an acquisition confirmation; (b) requesting for a license; (c) issuing and delivering the license to End User; (d) verification of license on the User's computer; (e) storing the license on the User's computer; (f) periodic tracking of activation state, (g) another action with the User's license.

A method is provided for setting up a network for Internet Protocol (IP) communication between mobile terminals. A first mobile terminal determines a second mobile terminal that will communicate with the first mobile terminal. The first mobile terminal generates network setup information of the first mobile terminal for the IP communication and performs network setup using the network setup information. The first mobile terminal generates a network setup message including network setup information of the second mobile terminal, and sends the network setup message to the second mobile terminal.

This computer data protection method of the present invention requires a user to enter a correct password for modifying any data. If wrong passwords are typed, this method forbids modification of any program modules. Further, if any program module is detected having unauthenticated modification, that program module is deleted and an original image of that program module is loaded to recover normal operation of the operation system. Additionally, a common password is also provided in the protection method. Some special function can use this common password to pass the detection of this method to perform any modification.

A method for preventing rendering of content at overlapping time periods on more rendering devices than permitted by a license associated with the content is disclosed. The method includes: transmitting the following to a rendering device of a user: the content, first software that is operative to receive the content and to associate keys with the content, identification information (ID) that is associated with the user, and second software that comprises a player for rendering the content, receiving the following information from the rendering device during rendering of the content: a number representation X which comprises a number representation in bits of a result obtained from encrypting together a number representation of a present time interval and the ID, both encrypted with a public key of a key pair generated at the rendering device, and a number representation which comprises a number representation in bits of a share (SH) of a private key of the key pair generated at the rendering device, and detecting an attempt to render the content at overlapping time periods on more rendering devices than permitted by the license associated with the content based on a determination that number representations X received from separate rendering devices are identical, and number representations Y received from the separate rendering devices and paired with the number representations X received from the separate rendering devices are different. Related apparatus and methods are also disclosed.

The embodiment of the invention discloses a system, a method and equipment for broadband access network multicast control. The system comprises an access control subsystem and a user subsystem, wherein the access control subsystem is used for generating multicast encryption keywords, sending the multicast encryption keywords to the user subsystem, encrypting multicast frames sent to the user subsystem through the multicast encryption keywords after receiving a subscription request sent by the user subsystem and sending the encrypted multicast frames to the user subsystem; and the user subsystem is used for sending the subscription request to the access control subsystem to request the multicast frames and decrypting the received multicast frames encrypted by the access control subsystem according to the received multicast encryption keywords sent by the access control subsystem. In radio type (shared media) access applications, only authorized users of the invention can use multicast service data to prevent illegal users from using the multicast services, and improve the security of multicast authority control.

A protective module for a data transmission port includes a plugging element and an unlocking element. The plugging element includes an extension portion and an end portion. The extension portion is inserted into the data transmission port. The end portion obstructs an opening of the data transmission port and is made of a first magnetically attracting material. The unlocking element includes an attraction portion adapted to attract the end portion and made of a second magnetically attracting material. The end portion of the plugging element escapes from the data transmission port as a result of magnetic attraction between the end portion of the plugging element and the unlocking element as soon as the unlocking element approaches the plugging element plugged into the data transmission port. Therefore, the protective module prevents external devices from getting connected to the data transmission port and prevents dust intrusion.
