An embodiment of the invention includes an interface that receives a user identifier, and a processor that identifies the number of characters in the password for the user identifier. The interface receives input such that the number of characters in the input is greater than the number of characters in the password. The interface can receive additional input such that the number of characters in the additional input is greater than the number of characters in the password. The processor can compare the password to the first X characters of the input, where X equals the number of characters in the password. The processor can compare the password to the last X characters of the additional input. The processor can determine whether to authenticate the user based on the comparison of the password to the first X characters of the input and the last X characters of the additional input.

Password protection under close input observation based on dynamic multi-value keyboard mapping

A system and method for automatically reconfiguring a keyboard layout display to facilitate entry of password characters. The system analyzes the password while setting it, and will save a required keyboard layout for each character. A method includes obtaining an encoded sequence of keyboard layouts mapped to a corresponding characters sequence of a user password, receiving input of a password character and determining whether the character input is correct. If the character entered is correct: decoding the keyboard layout sequence to obtain a correct keyboard layout associated with a next password character to be entered; and automatically displaying the correct keyboard layout associated with a next character to be entered; or if the character entered is not correct: decoding the keyboard layout sequence to obtain one of: a correct or incorrect keyboard layout associated with a next password character to be entered; and automatically displaying the correct or incorrect keyboard layout on the device.

Changing keyboard layout automatically while entering a password

A method, system, and computer program for improving productivity of code development is provided. The method includes calculating an edge weight between nodes of a directed graph for a code project, where the nodes include a source node and a sink node, the source node corresponds to a method and the sink node corresponds to a testcase, calculating a flow value from an identified source node to the sink node, where the identified source node includes a source file of the method that has been changed and generating a list of testcases that correspond the sink node whose calculated flow value is greater than or equal to a threshold flow value.
