Abstract: The generation of a web site preview based on client presentation state of the client that will render the web site preview. Upon a service receiving a request to provide preview data for a web site preview corresponding to a web site identifier, the service determines client presentation state of the client(s) that is or are to render a web site preview using preview data that is to be provided in response to the request. The service selects a preview template at least in part based on the determined client presentation state. The service also populates the selected preview template with content from the web site to thereby generate preview data representing a preview of the web site identified by the web site identifier. The preview data is thus tailored to the presentation state of the client.

Abstract: A method for expedited confirmation and inclusion of orphaned transactions in a blockchain network includes: receiving new blockchain transactions, confirming each of the new blockchain transactions, receiving a new block accepted for the blockchain that includes only a subset of the confirmed blockchain transactions, generating a subsequent new block that includes at least the orphaned transactions that were not included in the received new block, and transmitting the subsequent new block to one or more other nodes in the blockchain network.

Abstract: A method for facilitating communications while protecting customer privacy through cryptography and withholding of personally identifiable information includes: storing, in a memory of a processing server, contact data and a reference value associated with a first external computing device; receiving, by a receiver of the processing server, a communication request from a second external computing device, the communication request including at least the reference value and a digital signature; validating, by a processor of the processing server, the digital signature using a communicator public key of a cryptographic key pair; receiving, by the receiver of the processing server, a communication message from the second external computing device; and forwarding, by a transmitter of the processing server, the communication message to the first external computing device using the stored contact data following successful validation of the digital signature.

Abstract: The disclosed subject matter includes methods, systems, and networks for authentication based on physical characteristics of a mobile device. A computer-implemented method performed by a payment network includes receiving an image of a part of a mobile device from an image capturing device that communicates with the payment network, wherein the mobile device includes digital card data of a customer. The computer-implemented method may also include comparing a physical condition of the part of the mobile device shown in the received image to the physical condition of the part of the mobile device shown in a stored image. In addition, the computer-implemented method may include authenticating or declining a transaction involving the digital card data based on the comparison of the physical condition of the part of the mobile device in the received image and the stored.
