Definitions

  • the invention relates to out-of-band delivery of license information, such as for example using an SMS (short messaging system) protocol, with the effect of delivering that license information to a destination in a closed content distribution system, using, at least in part, a channel other than that used for content distribution itself.
  • SMS short messaging system
  • Closed content distribution systems include end-to-end systems, including publishing servers, content distribution servers and playback devices, where the content that is playable on playback devices can be completely controlled through appropriate security techniques, and those security techniques make it relatively difficult for any unauthorized third party to distribute content that would be playable on the playback devices.
  • a closed content distribution system includes a playback device, such as a game station, such as for example found in an arcade, a user's home, or a similar type of location, using which content can be executed or presented interactively with one or more game players.
  • Content can be distributed to such a playback device using a download connection to a distribution network, or using transport of physical media (such as for example CD-ROMs or DVDs) including the content, possibly encrypted using a symmetric key, or possibly encrypted using an key pair such as in a public key cryptosystem.
  • the playback device might operate alone or in conjunction or cooperation with other devices, such as for example a display monitor or an input controller.
  • the closed content distribution system can include reception by the playback device of (1) content to be executed or presented, and of (2) licenses indicating scope of rights by users to execute or present that content.
  • One problem is that requirements of channels for distribution of content and licenses can differ significantly, including the amount of information for distribution, the frequency or timing of those distributions, and the degree of time latency tolerable for those distributions. It might be common to distribute several gigabytes of information for content, using one or more DVDs once per week, and to accept a time latency of several days for that distribution. In contrast, it might be common to distribute at most several kilobytes of information for licenses, but it might be advantageous to receive that license information within minutes of a request, such as for example in response to the user presenting proof of payment for the license.
  • the license enables the content to be determined to be executable, valid, or both, with the effect that the content might be received at the player device any time in advance of the license.
  • a closed distribution system includes a playback device including a computing device capable of general purpose processing, and capable of enforcing mandatory execution of selected security software, such as for example a secure processor.
  • the playback device is capable of receiving content to be executed or presented, such as for example embedded on physical media delivered to a location at or near the playback device. Operation of the secure processor assures that only authorized content is executed or presented by the playback device, and any appropriate licensing or rights information is interpreted and enforced by the playback device.
  • the secure processor has access to external memory on which that secure processor can maintain rewritable information, such as for example game state information, license information, and user information, authenticated or hidden using a cryptographically-secure technique, such as for example digital encryption or digital signature.
  • rewritable information such as for example game state information, license information, and user information
  • a cryptographically-secure technique such as for example digital encryption or digital signature.
  • the playback device might be coupled to a LAN (local area network) or a secured enterprise network, with the effect that content delivered to devices coupled to one of those networks can be available to the playback device.
  • a user (such as a game-player) associated with a playback device makes a connection to a license server, to request a license to selected content.
  • the connection includes a communication link outside the closed content system, and provides the user with a technique for communicating with the license server, without involving the playback device in that connection.
  • the user might request a license using SMS (short messaging system) or another technique with the effect of sending a relatively small amount of information to request a license for specific content (whether application program, media content, or otherwise).
  • the license server receives the request, determines if a license should be issued, and responds to the request.
  • the license server might respond to the request using SMS, with the effect of providing the user with an alphanumeric or numeric code. This has the effect of allowing the user to input that alphanumeric or numeric code to the playback device, which can determine if that alphanumeric or numeric code authorizes the user for the selected content.
  • the alphanumeric or numeric code might represent information included in a license message.
  • the alphanumeric or numeric code might include a hexadecimal (or other radix) representation of a license message.
  • the playback device might receive that alphanumeric or numeric code from the user using a keypad or other input device.
  • the playback device using its secure processor, can authenticate the license message, with the effect of determining whether the user is authorized to execute or present the selected content.
  • the license message might be encoded using a digital signature or a secure hash, with the effect that the playback device (or the secure processor) can determine if that license message is authentic. If that license message is in fact authentic, the playback device (or the secure processor) can determine if that license message grants the user sufficient rights to execute or present the selected content, and can control whether that selected content is executed or presented.
  • the alphanumeric or numeric code might include a representation of a content decryption key, using which the playback device might be able to decrypt content and access that content for execution or presentation.
  • content encryption and decryption includes a public-key cryptosystem, with the effect that the content decryption key would include a decryption key privately associated with the content, encrypted by an encryption key publicly associated with the specific playback device. This would have the effect that the alphanumeric or numeric code would only allow the playback device to execute or present the content if the selected content and the specific playback device were both associated with the information received from the license server.
  • an activation code might include an identity of the player and an identity of the content itself, either signed by the license server, or encrypted by a common key (such as for example a Diffie-Hellman shared secret) that can be computed by both the license server and the specific player.
  • the mandatory security software would, in such cases, enforce the computation of the secret key (using its private key and server public key) and decryption of the identities.
  • the mandatory security software may enforce the verification of a signature by the license server.
  • the mandatory security software would force the comparison of the player identity with its own tamper-proof identity and the identity of the content that the activation code is meant for.
  • the mandatory security software would separately authenticate the content identity with respect to the content data hash or signature, using a trusted server (such as for example a trusted content publisher) signature over those quantities.
  • communication between the license server and the user involves a commercial transaction.
  • the license server would receive information from the user sufficient to allow the license server to effect a purchase transaction by the user (such as for example, a credit card or debit card number the user is authorized to charge, an account or a subscription the user is authorized to use, and the like).
  • the license server would issue the alphanumeric or numeric code in response to the user having sufficient authorization to use the playback device; that sufficient authorization would include proof that the user had (either in the past or just then) purchased the right to use the content with that playback device.
