615 results about "Information Card" patented technology

Information cards are personal digital identities that people can use online, and the key component of an identity metasystem. Visually, each i-card has a card-shaped picture and a card name associated with it that enable people to organize their digital identities and to easily select one they want to use for any given interaction. The information card metaphor is implemented by identity selectors like Windows CardSpace, DigitalMe or Higgins Identity Selector.

Disclosed is a user-centered mobile internet identity managing and identifying method. User identity agency which is in charge of managing user identity information is set on a mobile platform by the method. An identity information card of a user can be created by the user through the user identity agency. Identity information can also be issued by a trusted third party through request and management of the user identity agency. The identity information of the user is shown in the form of a virtual card. The identity information of the user is managed by the user, and the user only needs to submit essential identity information needed by a website to the website. The submission of the identity information of the user needs to acquire authorization of the user, and therefore the user-centered characteristic and characteristic of user controlled identity information are shown in identity management. Identity authentication is conducted through a public and private key when the user needs to register or login on the website, and no longer relies on the identity authentication method of username/password. If a repeater (RP) is provided with a legal digital certificate, the digital certificate of the RP can be checked through the user identity agency by the system, and therefore phishing is prevented.

Answer sheet identification method

The invention relates to an answer sheet identification method, which comprises the following steps: dynamically filtering and obtaining a colorful image of an answer sheet; carrying out gray processing to the image; judging whether a gray image is the processing of a "black" image; carrying out local threshold value binarization processing; looking up to process a convex quadrangle on a binary image, wherein the convex quadrangle has a maximum area and is more than a certain threshold value, and four inner corners of the convex quadrangle are similar to straight angles; carrying out inclination and perspective distortion correction processing; intercepting a rectangular area, and carrying out normalized image processing; identifying student numbers; identifying test paper numbers; and identifying answers. Due to the portability of a mobile terminal, a research that a mobile terminal camera is used for scanning an answer sheet and a relevant algorithm is used for identifying becomes very meaningful, the working efficiency of a teacher can be obviously improved, and the answer sheet identification method is helpful for teaching work. The answer sheet identification method also can be used for reference into the identification statistical processing of information cards, such as questionnaires, votes and the like, and has a wide application value.
