This invention is directed to an electronic device with an embedded authentication system for restricting access to device resources. The authentication system may include one or more sensors operative to detect biometric information of a user. The sensors may be positioned in the device such that the sensors may detect appropriate biometric information as the user operates the device, without requiring the user to perform a step for providing the biometric information (e.g., embedding a fingerprint sensor in an input mechanism instead of providing a fingerprint sensor in a separate part of the device housing). In some embodiments, the authentication system may be operative to detect a visual or temporal pattern of inputs to authenticate a user. In response to authenticating, a user may access restricted files, applications (e.g., applications purchased by the user), or settings (e.g., application settings such as contacts or saved game profile).

A method of analyzing and recognizing fingerprint images that utilizes vector processing of a vector field that is defined as the tangential vector of the fingerprint ridge curves is disclosed. The raw fingerprint image is divided into blocks, filtered to remove noise, and the orientation direction of each block is found. This allows the ridge curves to be enhanced and approximated by piece-wise linear approximations. The piece-wise linear approximations to the ridge curves allow the minutiae to be extracted and classified and a fingerprint minutiae template to be constructed. An enrollment process gathers multiple fingerprint images, creates fingerprint minutiae templates corresponding to the acquired fingerprint images, and stores the templates and other data associated with the respective individual or the enrolled fingerprint in a fingerprint database. In an identification process, an unknown raw fingerprint image is obtained via a fingerprint scanner and processed similarly to the enrollment process such that the fingerprint minutiae template of the unknown fingerprint is compared to one or more previously enrolled fingerprint minutiae templates. The identity of the individual associated with the unknown fingerprint is thereby ascertained. In addition, live finger detection can be accomplished in conjunction with the verification or identification process through analysis of the fingerprint image thus enhancing the security of the overall system.

A one-to-many identification system for access control allows a search rate of up to ˜1:30,000 in a real time. The system uses a very fast pattern based screening algorithm followed by a fast minutiae based screening algorithm. A fused score of both algorithms is used as a decision metric to screen out a vast majority of all the templates after the second stage. The remaining templates are sent to a full minutiae based algorithm to obtain a minutiae comparison score. If the result is still inconclusive after the third stage, a full pattern based algorithm is run, and its score is fused with the minutiae comparison score. The system also uses an adaptive classification technique which minimizes a distance between each template and a number of templates. The system can be realised as a standalone unit or on a server.

The present invention enables permanent biometric authentication without the risk of forgery or the like. The present invention enables living-tissue discrimination as well as biometric authentication. The roughness distribution pattern of deep-layer tissue of the skin covered with epidermal tissue is detected, thereby extracting a unique pattern of the living tissue. Then, biometric authentication is performed based upon the detected pattern. The roughness distribution pattern of the deep-layer tissue of the skin is optically detected using difference in optical properties between the epidermal tissue and the deep-layer tissue of the skin. In this case, long-wavelength light, e.g., near-infrared light is used as illumination light cast onto the skin tissue. A fork structure of a subcutaneous blood vessel is used as the portion which is to be detected, for example. The portion which is to be detected is determined based upon the structure of the fork structure. In this case, the living-tissue discrimination may be made using the subcutaneous blood vessel.

Determining if the enrollment window remains open may be by determining the existence of one of a stability indicator and an instability indicator.

A sliding window of flash blocks is used to reduce wasted space occupied by stale data in a flash memory. The sliding window slides downward over a few flash blocks. The oldest block is examined for valid pages of data, and the valid pages are copied to the end of the sliding window so that the first block has only stale pages. The first block can then be erased and eventually re-used. A RAM usage table contains valid bits for pages in each block in the sliding window. A page's valid bit is changed from an erased, unwritten state to a valid state when data is written to the page. Later, when new host data replaces that data, the old page's valid bit is set to the stale state. A RAM stale-flags table keeps track of pages that are full of stale pages.
