DEVICE FOR PREVENTING LOGGING OF CLIENTS INPUT DATA IN A COMPUTER SYSTEM

摘要

A device for preventing logging of client input data in a computer system, characterized in that it includes a first transmission interface used to connect the smart electronic device, a second transmission interface used to connect the computer system, and a data encryption chip for encryption of the input data. The data encryption chip is set between the first and second transmission interfaces and is used to encrypt data input from the first transmission interface, and then transmit the encrypted data to the computer system via the second transmission interface. The device allows for the use of a smart electronic device as a real keyboard, and the computer system permits the data encryption chip to encrypt the data input by the smart electronic device, which are then sent to the computer system, helping to prevent logging of keying data with higher efficacy and applicability.
