An authentication device includes an operation panel, a registered handwriting procedure acquiring portion, a long-pressing detecting portion, a handwriting detecting portion, and a handwriting authentication portion. The registered handwriting procedure acquiring portion acquires information of a registered handwriting procedure from a storage portion in which the information of the registered handwriting procedure has been stored, which represents a handwriting procedure including a trajectory of a handwriting operation performed on the operation panel and at least one of a time, a speed, and a number of strokes of the handwriting operation. The handwriting detecting portion detects the handwriting procedure in the handwriting operation performed on the operation panel, during a period in which the long-pressing operation is continuously detected. The handwriting authentication portion determines whether the detected handwriting procedure satisfies a predetermined approximation condition with respect to the acquired registered handwriting procedure, thereby determining whether authentication has succeeded or failed.

Certain aspects of the present methods and systems may focus on computer implemented methods of obtaining digitized hand-writing data corresponding to a sample of a needed code point of a set of code points. Such methods may include: obtaining a sample of digitized handwritten text, the sample of digitized handwritten text including glyph data corresponding to a first glyph, the first glyph corresponding to the needed code point of the set of code points; associating the first glyph with the needed code point; identifying stroke data in the glyph data, the stroke data corresponding to a stroke component of the first glyph, determining a plurality of dimensional values of the stroke component in the stroke data; and associating the plurality of dimensional values with a new code point sample of the needed code point in a code point set data structure.

Disclosed are methods and systems for generating digital memorabilia including: providing a digital memorabilia signor with a digital photograph, a digital sports jersey, or a combination thereof; receiving at least one of an electronic signature or an electronic written message from the digital memorabilia signor to be embedded in the digital photograph, the digital sports jersey, or the combination thereof; embedding the at least one of an electronic signature or an electronic written message from the digital memorabilia signor into the digital photograph, the digital sports jersey, or a combination thereof to form the generated digital memorabilia; sending the generated digital memorabilia including the electronic signature and the electronic written message to a verification service to verify authenticity of the electronic signature and electronic written message in the generated digital memorabilia; and delivering the generated memorabilia to a digital receiver.

A method of encoding content data into a digital image includes determining bit values of a pixel within the digital image, and modifying the bit values within the pixel based on content data to be encoded in order to encode the content data into the digital image. The step of determining the bit values of a pixel within the digital image includes determining a binary representation of the bit values of the pixel. The step of modifying the bit values includes determining a binary representation of the content data to be encoded within the pixel and encoding the content data using a reversible binary operation.

A method of verifying the identity of a user at an authentication server that includes receiving user data relating to a signature gesture entered by a user at a computing device, the user data having a plurality of sample points, verifying the user data at the authentication server by comparing to reference signature data, encoding a verification message within a digital image, and notifying the user that their identity has been verified on the basis of the user data received from the computing device.

Disclosed are methods and systems for generating digital fantasy sports memorabilia including: providing a digital fantasy sports memorabilia signor with a digital fantasy sports photograph, a digital fantasy sports jersey, or a combination thereof; receiving at least one of an electronic signature or an electronic written message from the fantasy sports digital memorabilia signor to be embedded in the digital fantasy sports photograph, the digital fantasy sports jersey, or the combination thereof; embedding the at least one of an electronic signature or an electronic written message from the digital fantasy sports memorabilia signor into the digital fantasy sports photograph, the digital fantasy sports jersey, or a combination thereof to form the generated digital fantasy sports memorabilia; sending the generated digital fantasy sports memorabilia including the electronic signature and the electronic written message to a verification service to verify authenticity of the electronic signature and electronic written message in the generated digital fantasy sports memorabilia; and delivering the generated fantasy sports memorabilia to a digital fantasy sports receiver.

A handwriting geometry recognition and calibration system by using neural network and mathematical feature includes: a pre-processor for pre-processing coordinate points of geometric figures from user's handwriting so as to get a plurality of sample points which expresses the geometric figures to be recognized; a neural network connected to the pre-processor for receiving the sample points of the geometric figure and recognizing the geometric figure so as to acquire a coarse class of the geometric figure; and an mathematical logic unit connected to the neural network for receiving recognition results from the neural network, including coarse classifications which are used in a secondary classification by using conventional mathematical recognition logics so as to determine an exact geometry shape of the geometric figure; then the geometric figure being calibrated so as to get a geometry with a regular shape.
