    摘要： The present invention relates to a communication method, device, and system. The communication method include using low-frequency alternating magnetic field signals to control a communication distance between a first radio frequency (RF) device and second RF device. The communication device receives and uses a first low-frequency alternating magnetic field signal transmitted from a second RF device to control the communication distance to the second RF device. The communication system includes a first RF device and a second RF device. The first RF device generates and transmits a first low-frequency alternating magnetic field signal and receives a second low-frequency alternating magnetic field signal, and the second RF device generates and transmits the second low-frequency alternating magnetic field signal and receives the first low-frequency alternating magnetic field signal. The first RF device and the second RF device control the communication distance using the first and second low-frequency alternating magnetic field signals.

    摘要： A method for managing, by device, a matrix of keys, including at least one line and at least two columns, each key making short circuiting a line and a column when pressed. The method includes a sweeping phase, including, for each line: writing a predetermined logic value in the line; and for each column, reading a logic value in the column and comparing the read logic value and the predetermined logic value. For each line processed: the writing step is carried out during a predetermined time interval. For each column, the reading step is carried out during a first portion of the time interval. The sweeping phase further includes, for each column, writing the predetermined logic value in the column during a second portion of the predetermined time interval. The predetermined time interval is equal to the sum of the durations of the first and second portions.

    摘要： The solution provides a method of secret information entering into an electronic digital device by a user via the input/output device, when the electronic digital device assigns a multimedia information designed for interaction containing the elements (1) is such a way that their relation to control elements of the electronic digital device is variable between individual displays. Then, the user selects elements (1) of multimedia information designed for interaction assigned to elements (2) of secret information in an order corresponding with the order of elements (2) of secret information, so by selecting the elements (1) of multimedia information designed for interaction the user selects the elements (2) of secret information in given order.

    摘要： A system/method for preventing a computer virus from accessing message addresses is described. The system comprises an interception component or client plug-in that communicates with a messaging client and a messaging server. The interception component alters messages from the server and destined for the client. The interception component replaces message addresses in incoming messages with a unique identifier. The interception component also alters messages from the client destined for the server. The interception component replaces a unique identifier with a message addresses. A system/method for preventing keyboard sniffer programs from intercepting input, a system for preventing a computer virus from activating a send confirmation of a messaging client and a method for altering displayed objects to show encrypted data in decrypted form are also described and claimed. A system/method for reducing the impact of keyboard sniffer programs by altering keyboard input.
