Abstract: A method, at a terminal in a digital communications network, comprising: establishing direct or indirect communication access and linkage between the user-operated terminal and at least one remote computer(s) on which are stored, or by which access is available to prevent legible display of, stored user account object data; displaying indicia, or broadcasting data, representative of or indicating one or more predetermined criteria for selecting a subset of the stored user account object data; collecting data, representative of, or indicating, only the subset of the stored user account object data; and transmitting instructions to prevent legible display of the subset of the stored user account object data, according to the collected data representative of, or indicating, the one or more predetermined criteria for selecting the subset of the stored user account object data, from the terminal to the at least one remote computer(s). A terminal, system, and computer readable medium are also disclosed.

Abstract: This document describes a system and method for a device to communicate efficiently and securely with another device by utilizing two different types of schemes for the generation of data to be transmitted and the handling of received data.

Abstract: Embodiments relate to a wireless communication device of a group of wireless communication devices configured to communicate with a base station, the wireless communication device comprising a transceiver configured to receive a token from the base station and a processor configured to generate a first data structure on the basis of a function of the token and of a key ki of the wireless communication device and a second data structure comprising an identity idi of the wireless communication device, wherein the transceiver is further configured to broadcast the first data structure and the second data structure to the group of wireless communication devices and the base station.

Abstract: A system for point-to-point encryption is provided. A card reader system reads unencrypted card data stored on a magnetic stripe of a card and encrypts the card data, the card reader system being contained in a first housing. A point of sale device coupled to the card reader system and contained in a second housing separate from the first housing has a user interface for obtaining a transaction amount. A transaction request system transmits the transaction amount and the encrypted card data to an authorization gateway, wherein the unencrypted card data is prevented from being processed by the point of sale device.
