Abstract: A method includes: processing a request to execute a transaction of a virtual asset of a video game; responsive to the request, accessing a blockchain to perform an anti-fraud verification, including analyzing data of a prior transaction involving the virtual asset; responsive to the anti-fraud verification providing a result that does not indicate fraudulent activity, then generating transaction data based on an identifier for the first user account, an identifier for the second user account, an identifier for the virtual asset, and state data of the virtual asset, and submitting the transaction data to a node network, to write the transaction data to a block of the blockchain; receiving confirmation of the writing of the transaction data; responsive to receiving the confirmation, then updating a registry of virtual assets to transfer ownership of the virtual asset from the first user account to the second user account.

Abstract: A method includes: initiating a data channel over a networked gaming service, including generating a channel key, the channel key being used to encrypt content communicated over the data channel, and generating a first encrypted channel key by encrypting the channel key with a public key associated to an owner of the data channel; adding a participant to the data channel, including generating a second encrypted channel key by encrypting the channel key with a public key associated to the participant; wherein a message sent via the data channel includes encrypted content generated by using the channel key to encrypt content for the message, and further includes the first encrypted channel key and the second encrypted channel key.

Abstract: A method includes: processing a request to execute a purchase transaction for a virtual asset of a video game, to transfer ownership of the virtual asset from a first user account to a second user account, to transfer an amount of virtual currency from the second user account to the first user account; responsive to the request, accessing a blockchain to perform an anti-fraud verification, including analyzing data of a prior transaction involving the virtual asset that is stored to the blockchain; responsive to the anti-fraud verification providing a result that does not indicate fraudulent activity, then generating transaction data based on an identifier for the first user account, an identifier for the second user account, an identifier for the virtual asset, and the amount of virtual currency, and submitting the transaction data to a node network, to write the transaction data to a block of the blockchain.

Abstract: A CAPTCHA is presented on a display and a user of a hand-held controller such as a computer game controller is prompted to respond to the image. A correct response entails manipulation of a key on the controller and does not require input from an alpha-numeric keyboard.

Abstract: A machine readable quick response (QR) code or, if this fails, a human-readable passcode is presented on a display of a server device for scanning (or reading and human input) into a mobile device. The mobile device computes a response and returns it to the server. If the response is correct, WiFi setup information, which can include PII, is exchanged in an encrypted form between the two devices to support subsequent WiFi communication.

Abstract: To prevent legitimate message recipients from forging new messages and to encrypt messages for a specific set of recipients (channel), a root key is encrypted and combined with a base session management key to render a combined root key, which in turn is encrypted with a public key of at least one recipient device to render a session management key. The public key of each of “N” intended recipient device encrypts the combined root key to render “N” session management keys. The session management keys are then combined with the combined root key to render a multicast root key, which is signed with a private key of a sending device. The signed multicast root key is combined with the session management keys to render an encrypted, signed multicast root key that is used to encrypt digital information prior to transmitting the digital information.

Abstract: Aspects of the present disclosure relate to systems and methods for establishing an assistance output that takes into account client device latency information and sending the assistance output from the server to the client device. Client device information or the assistance output may include a stream of encrypted data packets.

Abstract: One or more device-specific serial numbers are processed by a chaotic function to render an output, which is used to derive at least one encryption key.

Abstract: A root key of a computing device that is typically “burned” into the device hardware at time of manufacture is used to establish a master key and if desired a Transport Layer Security pre-shaped key, a WiFi configuration key, and application verification keys. The keys established from the root key are stored in a region of flash memory, and this region of flash memory is then encrypted using a random encryption code.
