  • Patent number: 9501638
    Abstract: A device includes a memory and a processor coupled to the memory. The processor is configured to execute a management program, an application program, and a first security module. The management program presents a first list associated with the first security module to a user that includes a first item that represents the application program. The application program is executed in a security mode that is governed by the first security module when the first item is selected.

  • Patent number: 8745712
    Abstract: Provided are a computer program product, method and system for dynamically providing algorithm-based password/challenge authentication. A page is generated including selectable conversion operators to enable generation of an algorithm that applies at least one selected conversion operator of the selectable conversion operators on a string to generate a password. A created algorithm created using the at least one selected conversion operator in the page is received. The created algorithm is associated with a username for use in authenticating access by a presenter of the username to a computer service.

  • Patent number: 8739261
    Abstract: Provided are a computer program product, method and system for dynamically providing algorithm-based password/challenge authentication. A page is provided to authenticate a presenter of a username including a string and a field for entry of a password. An entered password entered into the page is received. An algorithm associated with the username is applied to the string included in the page to generate a generated password. A determination is made as to whether the entered password matches the generated password. The username is successfully authenticated in response to determining that the entered password matches the generated password.
