  • Publication number: 20120137372
    Abstract: Disclosed herein is an apparatus for protecting the confidential information of a mobile terminal. The apparatus for protecting the confidential information of a mobile terminal includes a storage unit and a confidential information management unit. The storage unit stores at least one piece of confidential information which requires security. The confidential information management unit moves the confidential information from the preset unsecured initial storage area of the storage unit, to the preset secured storage area of the storage unit and stores the confidential data in the preset secured storage area, in order to protect the confidential data, and exclusively manages the secured storage area. The secured storage area is set by the confidential information management unit.

  • Publication number: 20120137369
    Abstract: Disclosed herein is a mobile terminal with security functionality and a method of implementing the mobile terminal. The mobile terminal with security functionality includes a storage unit, a first module, a second module, and a third module. The storage unit stores a list of risky function combinations which may cause security risks. The first module monitors functions included in an application to be installed or running in the mobile terminal. The second module assesses security vulnerabilities based on whether a combination of the monitored functions corresponds to a risky function combination and/or security attributes of the mobile terminal. The third module takes countermeasures when a security vulnerability has been found based on the assessment.

  • Patent number: 7711158
    Abstract: A method and apparatus for classifying fingerprint image quality and a fingerprint image recognition system are provided. The method includes dividing a fingerprint image into a plurality of blocks, calculating and vectorizing quality classification parameters with respect to the respective blocks, obtaining quality classification values for the respective blocks by inputting the vectorized quality classification parameters into a trained quality classifier, and selecting a representative value of the quality classification values and determining the representative value as the quality of the fingerprint image. Since the quality of the fingerprint image can be accurately judged, reliability of the fingerprint image recognition system is increased.
