103results about How to "Secure distribution" patented technology

Software is securely distributed with limited usage rights. The software may be an executable program and / or one or more data files such as image or multimedia data files. The software includes an access control object which prevents at least some usage of the software without use of a first access control code. The first access control code is produced based on selected information characteristic of the user's computer system. The access control code is produced in a server computer to which the user directs a request for the access control code. The user makes a payment to receive the access control code, which is then downloaded to the user's computer system.

A media distribution system is provided whereby devices on a network are provided with native-mode, optimized content viewers adapted to receive and present digital content provided elsewhere on the network. An agent is downloaded to a device, where it gathers information regarding the device environment and uses that information to identify the appropriate application for that device. The appropriate application for a particular device is then downloaded to the device to enable the device to present the content to a user.

A method to securely distribute media content such as Audio or Video with associated media information as part of a media package, in a media distribution system. The media content is encrypted and can be decrypted using a code, process or algorithm called a program key which is further encrypted and stored in the media package as one or both of a service encrypted program key or a locally encrypted program key. When a payment arrangement is not required the program key can be obtained by decrypting the locally encrypted program key, but when a payment arrangement is required, the locally encrypted program key cannot be decrypted or is not present and the service encrypted program key must be decrypted using a decryption message provided by a server after the payment arrangement is made. Media content, the locally encrypted program key and the service encrypted program key are re-encrypted periodically to ensure the security of the media package.

A mediating apparatus is provided on an IP network, and stores an access control list (ACL) retained in a VPN gateway unit. The mediating apparatus: receives a retrieval request from a VPN client unit; acquires a private IP address of a communication unit by reference to ACL; searches DNS to acquire therefrom an IP address of the VPN gateway unit; generates a common key that is used for authentication between the VPN client unit and the VPN gateway unit and for encrypted communication therebetween; sends the IP address of the VPN gateway unit, the private IP address of the communication unit, and the common key to the VPN client unit; and sends the IP address of the VPN client unit and the common key to the VPN gateway unit.

One example embodiment includes a method for constructing a unified namespace carried out by a domain manager service executing on a domain node in a domain network comprised of domain nodes. The method includes establishing a single, hierarchical domain tree that encompasses digital computers in a distributed data service network, where the domain manager service sends a request to all domain member nodes requesting that each domain node export the root of its sub-domain to the domain manager. The method also includes receiving the exported sub-domain roots. The method further includes grafting onto a domain root of the domain manager service the received exported sub-domain roots.

A method and system automatically generate a list of participants physically present at a meeting and distribute permission to the participants. Identity and key information is collected from the participants during the meeting using at least one personal area network. The identity and key information is stored on a delegation device. Permission to access the services is distributed to the participants over at least one personal area network using the delegation device. The delegation device may include an access control matrix or moveable icons for organizing and distributing participant and permission information.

Methods and Systems for securely distributing software in a subscription-based environment are provided. In an example embodiment, a Game Security Facility (“GSF”) associated with a game server is used to manage secure communications with game clients. The GSF typically manages secure communication of the accounting and billing information and secure communication of game session data. In typical operation, the game client generates a pass-phrase that transparently includes a unique identifier of the machine upon which the subscription software will reside. RSA-type key pairs that are then generated using this pass-phrase will be associated uniquely with both the game player and with the machine upon which the software resides, thus preventing unauthorized copying to another machine or unauthorized use by a third party. A public key generated using this pass-phrase is forwarded to the GSF, which uses it to generate a unique one-time random session key (for use as a symmetric key) for each session with the game client. The session key is then encrypted for the game client using the public key of the client. Session data, including the original game files downloaded upon successfully subscribing, are then transmitted between the game server and the game client using encrypted versions of the session key. In one embodiment, the game client can upgrade the machine upon which the subscription data resides, cause the session keys to be reissued using a new public key, and retain access to previously downloaded data.
