Abstract: There is described an apparatus for generating a cryptographic key using data representative of an analogue source. The apparatus has a number generator which processes the data representative of the analogue source to generate an intermediate key, the intermediate key being a number, and a data store for storing a mapping key, the mapping key being a number predetermined to combine with the intermediate key in accordance with a monotonic mapping function to generate a desired cryptographic key. Preferably, the number generator processes the data representative of an analogue source in accordance with stored process data, determined by a training process, which indicates attributes of the data whose values are to be measured and adjustment data for adjusting the values to improve the repeatability of generation of the intermediate key.

Abstract: Example methods, systems, computer-readable media, and apparatuses for on-screen optical fingerprint capture for user authentication are presented. These allow for the authentication of a fingerprint where the fingerprint image is propagated in a glass layer before being captured by a camera. In some examples, such propagation can result in multiple fingerprint images resulting from total internal reflection within the glass layer. Feature information can then be determined from the captured image of the fingerprint, which can include multiple fingerprint images. The amount of feature information can then be reduced. A histogram associated with the captured image based on the reduced number of features can be generated, and a user can be authenticated based on the histogram.

Abstract: Method for validating a trusted user of an electronic device, which electronic device comprises an input surface, e.g. on a key, dedicated for application of a user finger; a user input data sensor system, including a fingerprint sensor connected to the input surface for detecting user input fingerprint data, and a tremor sensor for detecting user input tremor data; data access to stored user input data corresponding to a trusted user; and a main processor system configured to match detected user input data with stored input data for validation of a trusted user. A triggering algorithm may run in a sub-sensor system, for sensing device handling and comparing sensed device handling with stored data. If the comparison reveals that user input is likely to occur based on the, a command is sent to the main processing system to trigger activation of tremor sensing and matching.

Abstract: A fingerprint enrolling method, a fingerprint enrolling apparatus, and a terminal device are provided. The method includes the following operations. Whether an image-quality fluctuation amplitude of fingerprint images of a user exceeds a preset image-quality fluctuation threshold or image-quality fluctuation threshold range is determined according to image quality of a current fingerprint image of the user currently acquired and image quality of a historical fingerprint image of the user previously acquired. The current fingerprint image is enrolled into a fingerprint database based on a determination that the image-quality fluctuation amplitude does not exceed the image-quality fluctuation threshold or the image-quality fluctuation threshold range.

Abstract: A fingerprint unlocking method is provided. The method includes the follows. Fingerprint information is acquired. A target group number of a group of fingerprints that is most similar to the fingerprint information is determined from among preset fingerprint matching data; where the preset fingerprint matching data corresponds to N groups of fingerprints, each group of fingerprints corresponds to multiple fingerprint templates and has one unique identification group number, and N is an integer greater than 1. Match the fingerprint information with fingerprint templates of fingerprints corresponding to the target group number. A terminal is unlocked when a target matching value between a fingerprint template of the fingerprints corresponding to the target group number and the fingerprint information is determined, where the target matching value is greater than a first preset threshold. A terminal is also provided. Efficiency of fingerprint unlocking is improved with aid of embodiments of this disclosure.
