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 distributed subscriber management system and method that controls access to a network preventing unauthorized traffic through the access network and providing centralized access control between user networks. The system and method provide controlled access through the use of one of several technologies including user authentication, using PAP, CHAP, RADIUS, TACACS+, or other standard authentication means. The method includes the steps of receiving a connection request from a user located on one of the User Networks; interrogating the user for userid and password information; encrypting the userid and password information; transmitting the encrypted information, via the access network, to an authentication server attached to one of a plurality of external networks; decrypting the information at the authentication server; and transmitting an authentication message from the authentication server of the external network to the access control node via the access network. The preferred method includes the additional step of challenging all data leaving the access control node.

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.

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 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.

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, the license being secured with a private key by a server, and the private key is not stored at the client; (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, wherein the verifying the license comprises validating, at the client associated with the application, the license received from the server without any modifications, and saving the license to the client.

A method for licensing a system for obtaining an X-ray image of a subject. The system employs flexible information carrier plates for computed radiography, which are exposed to X-rays and then scanned in a scanner. A license media is provided with a RFID transponder, which stores in its memory identification information referring to the system components as well as information referring to an amount of valid licenses available for use of the system components. When the identification information stored in the memory of the license media RFID transponder matches the identification information transmitted to the scanner by a processing and acquisition station the carrier plates are scanned automatically.

The invention discloses application uninstall preventing equipment which is resident in a mobile terminal to prevent a target application from being uninstalled from the mobile terminal. The application uninstall equipment comprises a view loader, an uninstall processor and an uninstall event monitor, wherein the view loader is suitable for creating a view and enabling the view to be located at the uppermost portion of a screen of the mobile terminal, the uninstall processor is used for removing the view, presenting an uninstall interface for receiving password input on the screen of the mobile terminal and removing the uninstall interface and enabling the uninstall operation of the target application to go on when a received password is matched with a preset password, and the uninstall event monitor is suitable for monitoring operating events of uninstalling the target application and indicating the view loader to create the view and then activating the uninstall processor later when the operation of uninstalling the target application is monitored. The invention further discloses a corresponding application uninstall preventing method and the mobile terminal including the application uninstall preventing equipment.

The invention provides a managing method of a shared key, which is used for realizing preservation and use of the shared key in a terminal of a communication system, which comprises the following steps: step 602, distributing the shared key when a user adds a network, adopting a public cryptography of an initial user to encrypt the shared key, and writing the encrypted shared key into a nonvolatile memory of a PC card through an interface of the PC card; step 604, inputting a username and a public password of the initial user in a dialing software interface when the user starts the terminal for the first time to log on the network; and step 606, decrypting the encrypted shared key which is read by the interface with the dialing software to obtain the shared key, and utilizing the structureof the shared key to extend a judge right protocol message so as to pass the judge right. Therefore, the invention facilitates net-surfing convenience of the user, ensures the use safety of the shared key and at the same time allows a plurality of users to go online with one same PC card.

A method, system and computer-usable medium for redisplaying data at a remote access client system from a secure computing environment. The redisplaying data includes receiving a request form the remote access client system for data, inspecting the request for potential unauthorized or malicious retransmission. Modifying the data, by filtering audio data or transforming graphical data prior to sending the requested data is performed to prevent the unauthorized or malicious retransmission.
