  • Patent number: 10043073
    Abstract: Methods and systems for detecting changes, alterations and forgeries in documents utilize digital fingerprinting. A set of documents of a given type that are known to be altered or forgeries are scanned and “fingerprinted” to build a forgery database. Suspect documents are scanned and the resulting fingerprint data is used to query the forgery database to look for matching records, although a match need not be exact. Matches may be counted and compared to a threshold number to assess a confidence that a document is forged or not. The fingerprinting may be directed to at least one authentication region of a document, and one or more features in a region may be incorporated into a fingerprint of the document.

  • Patent number: 8923575
    Abstract: An object area detection means detects an object area which is an area to be subjected to image processing from an input image. A reflection component reconstruction means calculates color information of the object area and a perfect diffusion component, which is a low-frequency component of the object area, and reconstructs a surface reflection component based on the color information and the low-frequency component. An albedo calculation means calculates an albedo, which is color information obtained by removing shading information, which is information that represents luminance of the perfect diffusion component, from the perfect diffusion component. An albedo correction processing means reconstructs a surface reflectance of the object area based on the albedo and the color information in the object area, and then calculates the corrected albedo, which is color information obtained by correcting the albedo based on the surface reflectance.

  • Patent number: 8842887
    Abstract: Biometric data, suitably transformed are obtained from a biometric input device contained within a stand-alone computing device and used in conjunction with a PIN to authenticate the user to the device. The biometric template and other data residing on the device are encrypted using hardware elements of the device, the PIN and Password hash. A stored obfuscated password is de-obfuscated and released to the device authentication mechanism in response to a successfully decrypted template and matching biometric sample and PIN. The de-obfuscated password is used to authenticate the user to device, the user to a remote computer, and to encrypt device data at rest on the device and in transit to and from the remote computer. This creates a trusted relationship between the stand-alone device and the remote computer. The system also eliminates the need for the user to remember and enter complex passwords on the device.

  • Patent number: 8781230
    Abstract: Video-based handwriting input for biometric signature data collection is provided. The invention is implemented by finding all of the relative positions among all light points of light sources when all light sources mounted on a stylus are turned ON. An image is captured including effective strokes and digital data of pen pressure with a digital camera when a user writes on a writing surface with a stylus having a light source indicating x-y coordinates of strokes. The images are time-stamped. The stylus includes a micro-switch. When the stylus touches the writing surface, the micro-switch is turned on to let the light source indicating x-y coordinates of strokes turn ON and generate a light point. Effective stroke images and digital data of pen pressure are extracted by comparing the captured images with the light point on the stylus.

  • Patent number: 8774519
    Abstract: Techniques are disclosed for generating landmark models based on exemplar portions of images (“patches”) that are known to include the target landmark (forming a “positive” set of landmark vectors) and those that do not (forming a “negative” set of landmark vectors). Theses sets of positive and negative landmark vectors, along with other landmark statistics, form a landmark model. When an unknown image is received, candidate landmark vectors may be generated based on the image's content (or portion thereof) and applied to the landmark model to rapidly reduce the dimensionality (complexity) of the candidate landmark vector space. Landmark models may be applied to the reduced-dimensioned candidate landmark vectors to identify the most likely point corresponding to the target landmark.

  • Patent number: 8752146
    Abstract: A technique provides authentication codes to authenticate a user to an authentication server. The technique involves generating, by an electronic apparatus (e.g., a smart phone, a tablet, a laptop, etc.), token codes from a cryptographic key. The technique further involves obtaining biometric measurements from a user, and outputting composite passcodes as the authentication codes. The composite passcodes include the token codes and biometric factors based on the biometric measurements. Additionally, the token codes and the biometric factors of the composite passcodes operate as authentication inputs to user authentication operations performed by the authentication server. In some arrangements, the biometric factors are results of facial recognition (e.g., via a camera), voice recognition (e.g., via a microphone), gate recognition (e.g., via an accelerometer), touch recognition and/or typing recognition (e.g., via a touchscreen or keyboard), combinations thereof, etc.
