  • Publication number: 20140325641
    Abstract: An apparatus for a face recognition, includes an ID assigning unit configured to assign one ID to a user when registering the user so that the ID is mapped to the user; and a sub-ID assigning unit configured to respectively assign sub-IDs to face images of the user which are different from each other so that the sub-IDS are respectively mapped to the face images when the face images are registered. Further, the apparatus includes a mapping table creation unit configured to create a mapping table in which pairs of the ID and the respective sub-IDs are mapped; and an authentication unit configured to search the mapping table to authenticate the user to provide an authentication result, upon receipt of a request of a user authentication.

  • Publication number: 20140301599
    Abstract: A method for a face recognition by a face recognition service server, includes receiving a face image that is photographed from a face registration terminal or a face recognition terminal; detecting a face area of the received face image; and quantifying at least one quality factor for the detected face area in order to determine whether the received face image is suitable as sample image required for face recognition. Further, the method includes selecting the received face image as the sample image required for the face recognition when the quality factor satisfies a predetermined quality criterion.

  • Publication number: 20140286548
    Abstract: An apparatus for identifying a fake fingerprint, the apparatus comprising: a prism having a fingerprint contact surface with which a fingerprint comes in contacted; an internal light source configured to irradiate light from the inside of the prism; an external light source configured to irradiate light from the outside of the prism; an image sensor configured to acquire diffused light image by the internal light source and transmitted light image by the external light source; and a controller configured to compare the diffused light image and the transmitted light image acquired by the image sensor to determine whether the fingerprint is a fake fingerprint or not.

  • Publication number: 20140254892
    Abstract: A face recognition apparatus comprising: a database that stores face information mapped to each corresponding user; a face recognition unit configured to recognize the face information of a user; a user management unit configured to classify the face information into groups of the users of which the face information is not similar one another so that the users having the similar face information does not fall within the same groups to store the classified face information in the database.

  • Patent number: 8670599
    Abstract: A fingerprint authentication apparatus and method which processes fingerprint data input through a plurality of fingerprint sensors and uses the processed fingerprint data in authentication to thereby increase security and performance. The fingerprint authentication apparatus includes a first sensor configured to acquire first fingerprint data from a user; a second sensor configured to acquire second fingerprint data that is different from the first fingerprint data; and a control unit configured to determine whether or not to authenticate the user based on similarities obtained from the comparison of each of the first fingerprint data and the second fingerprint data with registered fingerprint data.

  • Publication number: 20130223681
    Abstract: An apparatus for identifying a fake face is provided. A first eye image acquirer acquires a first eye image by taking a picture of a subject while radiating a first ray having a first wavelength. A second eye image acquirer acquires a second eye image by taking a picture of the subject while radiating a second ray having a second wavelength that is shorter than the first wavelength. A controller extracts a first area and a second area having brighter lightness than the first area from each of the first and second eye images, calculates a lightness of the first area and a lightness of the second area in the first eye image, and a lightness of the first area and a lightness of the second area in the second eye image, and determines whether the subject uses a fake face based on the calculated lightness.

  • Patent number: 8503824
    Abstract: Provided are a rolled fingerprint acquisition apparatus and method for accurately registering and synthesizing fingerprints. The rolled fingerprint acquisition apparatus selects a reference frame from among rolled fingerprint frames that are sequentially acquired, calculates the central locations of fingerprints included in the rolled fingerprint frames, sets an order in which the reference frame and rolled fingerprint frames are performed based on the central locations of the fingerprints, and registers and synthesizes the reference frame with the rolled fingerprint frames according to the set order.

  • Patent number: 8463002
    Abstract: Provided are a rolled fingerprint acquisition apparatus and method for automatically detecting the start and end of registration and synthesis to acquire an accurate fingerprint. The rolled fingerprint acquisition apparatus compares at least one of fingerprint characteristic information and the amount of variation between the fingerprint characteristic information to reference fingerprint characteristic information to determine whether to start or end registration and synthesis, wherein the fingerprint characteristic information is information about fingerprints included in rolled fingerprint frames that are sequentially acquired, and registers and synthesizes the rolled fingerprint frames according to the result of the determination.

  • Patent number: 8243131
    Abstract: Provided is a contactless fingerprint image obtaining apparatus using a mirror. The contactless fingerprint image obtaining apparatus obtains the entire region of a fingerprint using the mirror in a contactless manner. The entire region of the fingerprint includes a fingerprint region of the front direction coinciding with the optical axis of a single shooting unit, and fingerprint regions of left/right lateral sides that do not coincide with the optical axis. Accordingly, unwillingness of a user, distortion caused by contact of the user, quality reduction, which are the limitations of a related art contact type fingerprint image obtaining apparatus are solved. Simultaneously, a wide region of a fingerprint image including the lateral sides of a fingerprint that cannot be directly obtained by a related art contactless fingerprint image obtaining apparatus using only a single camera can be economically obtained.
