A face image processing method is provided. The face processing method comprising: extracting a plurality of features from a primary two-dimensional face image to generate a first feature vector; decomposing a three-dimensional face image into a plurality of base face images and a plurality of weighting factors corresponding to the base face images; generating a first two-dimensional code according to the first feature vector; and generating a second two-dimensional code according to the weighting factors.

Biometric data are obtained from biometric sensors on a stand-alone computing device, which may contain an ASIC, connected to or incorporated within it. The computing device and ASIC, in combination or individually, capture biometric samples, extract biometric features and match them to one or more locally stored, encrypted templates. The biometric matching may be enhanced by the use of an entered PIN. The biometric templates and other sensitive data at rest are encrypted using hardware elements of the computing device and ASIC, and/or a PIN hash. A stored obfuscated Password is de-obfuscated and may be released to the authentication mechanism in response to successfully decrypted templates and matching biometric samples. A different de-obfuscated password may be released to authenticate the user to a remote or local computer and to encrypt data in transit. This eliminates the need for the user to remember and enter complex passwords on the device.

A method and an apparatus for authenticating user using biometric information. The apparatus authenticates the user by performing: generating a first feature vector from first biometric information of the user obtained by the biometric sensor and multiplying the first feature vector by a plurality of pseudo-random number (PRN) matrices, respectively; generating a query template based on an index of an element having a maximum value among elements of a result vector of the multiplication between the first feature vector and the plurality of PRN matrices; and performing authentication for the user by comparing the query template with a pre-stored reference template of a subscribed user.

A method for protecting a biometric template, comprising the steps of: retrieving an original vector (V) representing said biometric template, said vector comprising a plurality of original elements (v.sub.1, v.sub.2, . . . v.sub.i, . . . , v.sub.n); mapping at least some elements from said original vector to a protected vector (P) comprising a plurality of protected elements (p.sub.1, p.sub.2, . . . p.sub.i, . . . , p.sub.nm+1), the mapping being based on multivariate polynomials defined by m user-specific coefficients (C) and exponents (E).

A method for security verification, an apparatus for security verification and a mobile terminal are provided. The method includes: determining whether a received touchscreen operation is a predetermined operation; acquiring biometric recognition verification information input by a user if the touchscreen operation is not the predetermined operation, and verifying the biometric recognition verification information; and performing verification processing corresponding to the predetermined operation if the touchscreen operation is the predetermined operation.

A method of image processing within an image acquisition device. In one embodiment an image including one or more face regions is acquired and one or more iris regions are identified within the one or more face regions. The one or more iris regions are analyzed to identify any iris region containing an iris pattern that poses a risk of biometrically identifying a subject within the image. Responsive to identifying any such iris region, a respective substitute iris region, containing an iris pattern distinct from the identified iris pattern to avoid identifying the subject within the image, is determined and the identified iris region is replaced with the substitute iris region in the original image.

Embodiments of the invention involve using biometric templates to wirelessly authenticate individuals. In one embodiment, a mobile device may generate a first biometric template and a first public value from a first biometric sample of a user and generate a first cryptographic key by passing the first biometric template to a fuzzy extractors generate function. An access device may generate a second biometric template from a second biometric sample of the user, generate a second secret cryptographic key by passing the second biometric template and the first public value to the fuzzy extractors reproduce function, encrypt the second biometric template with the second secret cryptographic key, and broadcast the encrypted template to a plurality of nearby mobile devices including the mobile device. If the mobile device is able to decrypt the encrypted template with the first cryptographic key, the access device can associate the user with the mobile device.
