Authentication method and system of biological characteristics of user

The invention discloses an authentication method and system of the biological characteristics of a user. The authentication method of the biological characteristics of the user comprises the steps that a client side sends an authentication request to a server; the client side receives a voice password from the server; the client side collects voice information and a face image of the user to be authenticated; the client side judges whether the voice information is identical to the voice password and whether the face image is effective; under the condition that the judgment results are both yes, the client side correlates voice information fragments to the face image; the client side calculates abstract values of the voice password, the voice information, a target image, correlated information and a first moment through a preset algorithm; the client side sends authentication content to the server; the client side receives an authentication response from the server. By means of the authentication method and system, the problem that the recognition and authentication mode of the biological characteristics is single in the prior art is solved, and therefore the effect that the identity authentication safety is improved in the biological characteristics recognition process is achieved.

Methods and apparatus for integration of declarative rule-based processing with procedural programming in a digital data-processing evironment

The present invention provides methods and systems for integrating a procedural computational model with a declarative computational model. For example, in one aspect, the present invention provides a method for integrating a plurality of procedural instructions in a procedural computational system with a plurality of declarative rules in a declarative computational system. In such a method, for each of the procedural instructions operating on one or more variables, a hash table indexed by variable names is utilized to determine whether any of these variables participate in at least one of the declarative rules. Upon execution of a procedural instruction that changes a variable participating in a declarative rule, other variables associated with the rule are updated so as to maintain a relationship imposed by the rule among the variables. The updating of the other variables is performed prior to execution of other procedural instructions. Further, for each of the updated values, changes associated with to updated variable are propagated to other rules, if any, in which the updated variable participates. The propagation of the change can be accomplished by modifying values of variables other than the updated variable so as to maintain relationships defined by these other rules. The integrated computational systems of the invention can find applications, for example, in workflow processing.

Method and system for identifying and delivering contextually-relevant information to end users of a data network

A method and system for identifying and delivering contextually-relevant information to end users of a data network is disclosed. A software plug-in is designed and adapted to work in cooperation with an electronic document reader software application. When a document is opened by the document reader application, the plug-in identifies relevant content within the document by means of keyword search rules utilizing keywords that are maintained in a keyword database. The plug-in then performs a markup of the original document for display to the user, either as a modification of the original document or in a separate popup window, by means of markup rules that extract relevant markup information from a contextual information database. In one preferred embodiment, the electronic document reader software application is Adobe Reader, and the keyword database contains a list of company names and associated product information. The plug-in performs a keyword search of the contents of the document in portable Document Format (PDF). Upon identification of a company name and/or a product in the subject document, associated product information is presented to the viewer. The product information may be supplemented with hyperlinks to company websites where additional product information, including purchasing information, may be found. The method is designed and adapted to execution on a computer network-based system.

Snapshot integral view field imaging full-polarization hyperspectral detection device

The invention discloses a snapshot integral view field imaging full-polarization hyperspectral detection device. The snapshot integral view field imaging full-polarization hyperspectral detection device is composed of a front optical lens set, an integral view field unit, a collimating lens set, a full-polarization modulation module, a spectrum light splitting module, an imaging lens set, an area array detector and a data collecting and processing system all of which are sequentially arranged in the direction of incident light. Light emitted by a two-dimensional spatial target sequentially enters the front optical lens set, the integral view field unit, the collimating lens set, the full-polarization modulation module, the spectrum light splitting module and the imaging lens set, and finally reaches the area array detector. The data collecting and processing system controls the area array detector to shoot a frame of image to obtain distribution information of hyperspectral images corresponding to polarized components; then the data collecting and processing system extracts and processes data of the frame of image to obtain information of the spatial morphology, the one-dimensional high spectrum and the full Strokes polarization parameter of the detected two-dimensional spatial target. By means of the snapshot integral view field imaging full-polarization hyperspectral detection device, three-dimensional information of the space, the spectrum and polarization can be obtained in real time.

Method for file system security by controlling access to the file system resources using externally stored attributes

The present invention is an algorithm that manages the ability of a user or software program to access certain protected file resources. This invention describes a method for file system security through techniques that control access to the file system resources using externally stored attributes. This invention accomplishes the described objectives in file system security by creating an external database containing auxiliary attributes for objects in the file system. During a file access attempt, an identifier of this file will be matched against a set of protected files in a security database. If that file is not in the database, there is not protection on the file and requester will be allowed to access the file. If a match does show that the file is protected there will be a determination as to whether the requester will be allowed access to the file. The basis for this access determination will be a set security rules defined in the external security attribute. This invention incorporates techniques and algorithms for attribute attachment, storage and organization of the associations to these attributes, and subsequent recognition of attached attributes. In this approach, the attributes would define authorization policy for controlling access to objects in the file system.
