A ticket authentication method and a ticket authentication device are provided. The ticket authentication method includes the following steps. A first electronic device outputs an e-ticket. A second electronic device acquires the e-ticket. The second electronic device outputs a visible light verification code. The first electronic device acquires the visible light verification code and generates a composite code according to a certification data and the verification code. The second electronic device acquires the visible light composite code, and determines whether the composite code matches the certification data and the verification code. When the composite code matches the certification data and the verification code, the second electronic determines that the authentication of the e-ticket is successful.

Ticket authentication method and ticket authentication device

A method and system for tracking eye recovery. The method includes: receiving eye data from an eyewear, wherein the eye data includes images acquired by an image capturing device in the eyewear; analyzing the eye data to determine an eye recovery status, wherein the analyzing is carried out by comparing the eye data to an initial set of eye conditions; and providing a notification of the eye recovery status.

Tracking eye recovery

A data encoding and decoding system including an encoding apparatus and a decoding apparatus is provided. The encoding apparatus is configured to patternize a data. The encoding apparatus displays the patternized data in a manner of dynamic twinkling. The patternized data twinkles in a predetermined frequency. The decoding apparatus is coupled to the encoding apparatus. The decoding apparatus is configured to capture the data which dynamically twinkles in a predetermined time period. The decoding apparatus performs a data processing operation on the captured data to identify the captured data. In addition, a data encoding and decoding method is also provided.

Data transmission apparatus, data read apparatus, data encoding and decoding apparatus, and method thereof for patternized data

A method and device of generating an image stream with verification data are provided. The method includes the following steps. First, determine at least one pixel in a first image according to a first encoding parameter. Then, generate a timing data sequence associated with information about the correlation between the verification data and time points according to a second encoding parameter and the verification data. Next, modify a pixel value of the at least one pixel in the first image to generate a second image according to the verification data corresponding to one of the time points in the timing data sequence. Lastly, generate the image stream including the second image.

Methods and devices of generating and decoding image streams with respective verification data

A method, an apparatus, and a system for generating and verifying a color barcode are provided. The method for verifying the color barcode is adapted to an electronic apparatus to execute verification with use of a color barcode certificate. In the method, direction information of a plurality of boundaries among a plurality of serially connected symbolic elements in the color barcode certificate is read to retrieve first authentication information of a first party. Each of the symbolic elements is one of at least two polygons, and colors of adjacent symbolic elements are different. Color information of the symbolic elements is then read to retrieve second authentication information of a second party. An identity of a holder of the color barcode certificate is verified according to the first authentication information and the second authentication information.

Method, apparatus and system for generating and verifying color barcode

A barcode structure includes at least one symbolic element row and a frame arranged at a periphery of the at least one symbolic element row. Each symbolic element row has multiple symbolic elements. Each symbolic element has different color from its adjacent symbolic elements, and the color of the frame is different from that of any symbolic element. A barcode encoding method includes: establishing multiple color combinations where a color of a frame is excluded, and each color combination comprising a main color and a sub color; performing a symbolic element row establishment procedure, which includes using a reference color as a color of a first symbolic element of a symbolic element row; deleting color combinations where the reference color is used as a main color; and selecting a color combination from remaining color combinations for coloring two symbolic elements that are sequentially connected with the first symbolic element.
