An electronic device for securing information, and a method therefor are provided. The electronic device includes a receiver for receiving an encrypted data from a server, the encrypted data being encrypted with an encryption key by a key cryptography based on a private information, a nonvolatile memory for storing the encrypted data, a decryptor for receiving the encrypted data from the nonvolatile memory, decrypting the encrypted data into an unencrypted data including the private information, and a volatile memory for storing the unencrypted data. The receiver authenticates a communication channel and receives the encryption key through the authenticated communication channel, and the decryptor receives the encryption key from the receiver and decrypts the encrypted data with the encryption key.

Method and apparatus for securing resting data in internet connected devices

A contactless payment device and method transmits a sequence of magnetic-field pulses directly to two or three magnetic-stripe read heads of a point-of-sale terminal. The baud rate at which the data is transmitted is modulated so that track data for one read head channel will be ignored by another read head channel, based on the change to the baud rate and/or the rate of change in the baud rate to improve acceptance of the transmitted pulses received by the read heads of the point-of-sale terminal.

Baud rate modulating magnetic stripe data transmitter, system, and method

A system and method of validating electronic encoded information from magnetic stripe card data transmitted as electronic stripe data includes a lump transmission stream. The lump transmission stream is read by at least two track channel readers each of which recognizes and reads only data corresponding to data to be read from a respective magnetic stripe represented in the lump transmission stream, which has data read from two tracks of magnetic card stripes. One track channel reader reads the first portion of the lump stream and discards the second portion of the stream, the second track channel reader reads the second portion of the stream and discards the first portion of the stream.

Lump sequences for multi-track magnetic stripe electronic data transmission

Devices, systems, and methods for securely converting a user's existing static payment card data into dynamic card data that can be authenticated by card issuers or by a stand-in service provider, such as a payment network or processor without requiring the card issuers to make infrastructure changes. The dynamic data can be provisioned onto a magnetic secure transmission device (MST) either directly from a card issuer or using a swiper type device. Devices, systems, and methods are also disclosed for securely provisioning a dynamic card onto the MST by the card issuer. These dynamic cards may be used to transmit modified one-time-use card track data from the MST to a point of sale using a dynamic-CVV methodology to provide higher levels of security during a transaction.
