Abstract: A method and system for verification of a pattern based passcode. A user input of a series of key inputs is received. A registered pattern for the user of a sequence of keyboard direction movements is retrieved. A first character input in the series of key inputs is identified. It is determined that the identified first character is not in an excluded group of characters, wherein the excluded group of characters are previously used first characters in a defined period or number of instances for the user. In response to having determined that the first character is not in the excluded group of characters, the series of key inputs after the first character input is compared with the registered pattern for the user.

Abstract: This invention relates to a method, system and computer program product for selecting an optimized solution in a computerised multiple-constraint problem space, comprising: receiving a linear function for optimization; receiving a set of constraints for the linear function; determining a first optimal solution for the linear function and initial constraints using linear programming solver; creating a new set of constrains using the first optimal solution as a constraint in addition to the initial constraints; creating a new quadratic function by adding a quadratic objective of slack variables to the linear function; and determining a solution to the quadratic function and new constraints using a quadratic programming solver.

Abstract: A method of generating a password. An embodiment includes: receiving a first user input defining a seed for the password, receiving a second user input defining a destination for the password, operating a coding function to generate the password from the first user input and the second user input, and outputting the password generated by the coding function.

Abstract: A method and associated device for moving an image of displayable content displayed on a touchscreen of the device. Movement of an object along the touchscreen of the device toward an outer edge of the touchscreen is detected, and in response, the displayed image is moved toward the outer edge in synchronization with the detected movement of the object. It is determined that the object has traversed the outer edge of the touchscreen so as to no longer be touching the touchscreen, and in response, one or more motion sensors are activated to monitor the object for continuing movement of the object. The one or more motion sensors ascertain the continuing movement of the object away from the outer edge, and in response, the displayed image is moved toward the outer edge in synchronization with the ascertained continuing movement of the object.

Abstract: A method and Web server for verifying a Web service request originating from a Web page is provided. The method includes matching the Web service request with a Web service. A sequence ID contained in the request is identified. The Web service request is verified if the identified sequence ID does not correspond with a previous sequence ID for the matched Web service. Additionally, the Web service does not verify a same Web service request twice.
