  • Patent number: 11928204
    Abstract: A TEE system that includes a first platform that runs a first TEE, a second platform that runs a second TEE, and a merging unit that is adapted to merge a first output from the first TEE of the first platform, with a second output from the second TEE of the second platform, so as to form an output of the TEE system. The first TEE and the second TEE are based on different implementations. In this way, the security of the system is improved, as a malicious actor even be able to access “t” machines, still would not be able to retrieve the secret unless there are multiple exploitable TEE vulnerabilities on all executing TEE platforms at the same time.

  • Patent number: 11930356
    Abstract: This document describes a three-party cryptographic handshake protocol in a wireless network in which a sighter receives, from a beacon, a packet including an exponentiation of a random value and a proxy value and generates an end-to-end encrypted ephemeral identifier (E2EE-EID) from the exponentiation of the random value and the proxy value. The sighter generates a message for an owner, selects a private key, and computes an exchanged key using the private key and the E2EE-EID. The sighter extracts a common symmetric key from the exchanged key, encrypts the message using the common symmetric key, and transmits the encrypted message to the owner.

    Abstract: Systems and methods seamlessly blend edited and unedited regions of an image. A computing system crops an input image around a region to be edited. The system applies an affine transformation to rotate the cropped input image. The system provides the rotated cropped input image as input to a machine learning model to generate a latent space representation of the rotated cropped input image. The system edits the latent space representation and provides the edited latent space representation to a generator neural network to generate a generated edited image. The system applies an inverse affine transformation to rotate the generated edited image and aligns an identified segment of the rotated generated edited image with an identified corresponding segment of the input image to produce an aligned rotated generated edited image. The system blends the aligned rotated generated edited image with the input image to generate an edited output image.

If the unique device identifier matches the authorized unique identifier, the client-side digital content delivery device uses the DCP to causes presentation of the digital movie by the display device paired to the client-side digital content delivery device.

  • Patent number: 11848930
    Abstract: This application describes methods, mediums, and systems for verifying a device for use in a messaging system. Using the device verification procedures described, a messaging system can securely authorize new devices to send and receive encrypted messages on behalf of a user, preferably without the need to share a private encryption key between the users' different devices. The application describes several techniques that can be used to provide such a system, including distributing a computer-perceptible code that encodes encryption information between a secondary device and a primary device. This allows the information to be distributed without intervention by a server. Other techniques provide unique ways to build and reverify authorized device lists, distribute encryption keys in chat channels, ensure that lists of authorized devices are distributed in the correct order and remain valid for an appropriate amount of time, add new devices to an ongoing or new conversation, and more.

  • Patent number: 11848901
    Abstract: Disclosed are systems and methods for improving interactions with and between computers in content providing, searching and/or hosting systems supported by or configured with devices, servers and/or platforms. The disclosed systems and methods provide a framework for delivering electronic messages to a recipient in an optimized manner based on current real-world and digital activities associated with the recipient. Once a message sent by a sender is received by the message platform, the message and information related to a user's activity is analyzed, and a delivery condition is determined by the messaging platform. The platform then sends the message according to that delivery condition, such that it is delivered to the user only upon the platform relaying the message thereon when the condition is satisfied or occurs.

  • Patent number: 11847638
    Abstract: A method includes establishing a first funds transfer account associated with a first device and a second funds transfer account with a second device, funding at least the first fund account, and selecting the second device as the recipient of a funds transfer from the first device. The method further includes sending a communications link request from the first device to the second device and receiving acceptance of the communications link request from the second device. The method then establishes a communications link between the first device and the second device, initiates a funds transfer from the first device to the second device, wherein the amount is designated at the first device, and verifies the funds transfer amount, the first funds transfer account, and the second funds transfer account. Then, the method transfers the amount to the second funds transfer account associated with second device.

  • Patent number: 11831761
    Abstract: Techniques described herein can be utilized to implement a protocol for performing an unbiased selection of a particular worker node among a plurality of worker nodes to execute a computational task. Nodes of a distributed network may register to join a group membership by generating quantities derived at least in part from a hierarchical data structure, such as an accumulation tree, whose parameters are defined by a manager node. The manager node may utilise the quantities provided by the plurality of worker nodes to perform an unbiased selection of a worker node from among the plurality of worker nodes to perform a computational task. The invention is particularly suited, but not limited to, for use in a blockchain network such as Bitcoin. In at least some cases, the manager node cannot determine, based on quantities supplied by the worker nodes, whether a particular worker node was selected to perform the computational task.
