The invention relates to a computer-implemented method for providing an alternative GUI to a client application. A proxy computer comprises a history with request sequences respectively representing a part of a workflow predefined by an original GUI. Each request sequence in the history has been transmitted previously from an original GUI displayed in a client application via the proxy computer and via a network to a backend application. The proxy computer intercepts a current request transmitted from the original GUI to the backend application via the network and the proxy computer, compares the current intercepted request with the request sequences in the history, identifies and evaluates a matching request sequence for generating the alternative GUI, the alternative GUI completely or partially implementing the part of the workflow represented by the identified request sequence and returns the generated alternative GUI via the network to the client application.

Proxy-computer-based provision of alternative graphical user interfaces

A method and system for authenticating an access to a service on a device that includes a touch-sensitive screen. An entry of a code to the touch-sensitive screen is received through at least one opening in a stencil at one or more predefined locations in the stencil positioned on the touch-sensitive screen. The one or more predefined locations define an access code; and it is determined that the entered code equals the access code, and in response, the access to the service on the device is granted.

Unlocking of a mobile device by a code received via a stencil on a touchscreen

A method and system for authenticating an access to a service on a device. After a stencil has been positioned on a touch-sensitive screen of the device: an entry of a code to the touch-sensitive screen is received through at least one opening in the stencil at one or more predefined locations in the stencil, wherein the one or more predefined locations define at least part of an access code; and it is determined that the entered code equals the at least part of the access code, and in response, the access to the service on the device is granted.

A computer implemented method for managing a password is disclosed. The method can include generating a first hash value corresponding to a first password. The method can also include determining whether the first hash value corresponds with a second hash value included in the set of hash values. Further, the method can include suppressing storage of the first password in the set of passwords in response to determining that the first hash value corresponds with a second hash value included in the set of hash values.
