  • Patent number: 11956359
    Abstract: A method is disclosed. The method includes receiving, by a processing network computer from a relying party computer associated with a relying party, a request for data associated with a user operating a user device. The processing network computer may retrieve first encrypted data of the user having a user-layer of encryption. The processing computer can then generate a second symmetric key to add a relying party-layer of encryption to the first encrypted data using a stream cipher. The doubly encrypted data may be transmitted to a user device that removes the user-layer of encryption on the first doubly encrypted data, and then adds a second relying party-layer of encryption to form second doubly encrypted data. The second doubly encrypted data may be transmitted to the relying party computer, which can remove both relying party-layers of encryption to gain access to the data associated with the user.

  • Publication number: 20240112628
    Abstract: An electronic device may include a lenticular display. The lenticular display may have a lenticular lens film formed over an array of pixels. A plurality of lenticular lenses may extend across the length of the display. The lenticular lenses may be configured to enable stereoscopic viewing of the display such that a viewer perceives three-dimensional images. The display may have a number of independently controllable viewing zones. The viewer may be particularly susceptible to artifacts caused by crosstalk at the edge viewing zones within the primary field of view of the display. Certain types of content may also be more vulnerable to crosstalk than other types of content. Therefore, to mitigate crosstalk artifacts, the pixel value for each pixel may be adjusted based on the viewing zone of the respective pixel and content information (such as texture information or brightness information) associated with the respective pixel.

  • Patent number: 11763311
    Abstract: When a user enters a resource provider location with a portable communication device, the portable communication device provides an indication to a transaction processing system that the portable communication device is currently at the resource provider location. At a later time when the user conducts a transaction with a portable transaction device, the fact that the user's portable communication device had been detected at the resource provider a short time ago is taken into account as a positive indicator that the transaction is not fraudulent. By verifying that both the portable communication device and the portable transaction device are present at the resource provider, the risk of approving a fraudulent transaction from a stolen portable transaction device can be reduced.
