1. A computer network system for preventing logging of input data; comprising:
a client side host computer; a data input and encryption device, linked with the client side host computer for data transmission; said data input and encryption device is provided with either of a self-encrypting keyboard, encryption mouse encryption touch panel or an encryption on-screen keyboard; said data input and encryption device is also fitted with a data input interface, permitting the clients to input textual data or output them after decryption; a decryption server, linked via Internet with the client side host computer for data transmission; said decryption server enables decryption of the textual output data after encryption by the data input and encryption device; and an application server, linked is Internet or private network with the decryption server for data transmission; said application serer could receive the textual data input from the data input and encryption device after decryption by the decryption server; as the textual data input by the client are decrypted by the remote decryption server, rather than the client side host computer, the hijacking behavior could be prevented efficiently to realize anti-logging of input data, and it is possible to receive the encrypted textual data from the client side without need of modifying the design of the application server. |
