A method, computer system, and a computer program product for securing message transmission is provided. The present invention may include linking, by a first terminal device, a communication interface to a first communication channel for a target application. The present invention may include, in response to a first message being inputted in the communication interface, encrypting, by the first terminal device, the first message with a key for the first communication channel. The present invention may include, transmitting, by the first terminal device, the encrypted first message via the first communication channel.

Message security

A method and system of authenticating a user are provided. A request for a resource is received by a server, from a user device. A predefined number is received from the user device. A first number and a second number are created. The first number is sent to the user device. A first discrete logarithm is determined based on a challenge code and the first number and sent to the user device. A first pass code is calculated via a second discrete logarithm based on the first discrete logarithm, the predefined number, and the first number. A second pass code based on the second discrete logarithm, is received from the user device. The first pass code is compared to the second pass code. Upon determining that the first pass code is identical to the second pass code, the user device is allowed access a resource associated with the computing device.

Multi factor authentication

A method and system of authenticating a user are provided. A request for a resource is received from a user device. A predefined number is received. A first number and a second number are created. A first discrete logarithm based on the first number and the predefined number is determined and sent to the user device, together with the second number. A second discrete logarithm is received from the user device. A first pass code is calculated via a third discrete logarithm, based on the second discrete logarithm, the first number, and the predefined number. A second pass code is received via a fourth discrete logarithm, based on the first discrete logarithm, the third number, and the predefined number. Upon determining that the first pass code is identical to the second pass code, the user device is allowed to access a resource associated with the computing device.

A computer-implemented method for processing objects on touch screen devices is proposed. According to the method, one or more grid sizes is determined, wherein the one or more grid sizes comprise one or more text grid sizes. The one or more text grid sizes are determined by at least one of character, word, sentence, and section. Based on the one or more grid sizes, the one or more objects on the touch screen could be divided into one or more grids. The objects on the screen could be selected discontinuously by selecting grids on the screen.
