A method of characterizing a word image includes traversing the word image stepwise with a window to provide a plurality of window images. For each of the plurality of window images, the method includes splitting the window image to provide a plurality of cells. A feature, such as a gradient direction histogram, is extracted from each of the plurality of cells. The word image can then be characterized based on the features extracted from the plurality of window images.

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.
摘要:
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.
摘要:
A system and method for facilitating authentication of an electronic signature includes receiving electronic signature data associated with an electronic signature of a signer, the electronic signature data comprising at least biometric data associated with at least one of the electronic signature and the signer. A signature icon is generated by using at least the received electronic signature data, wherein the signature icon comprises a coded visual representation of the electronic signature data. The signature icon is provided on a document signed by the signer by way of the electronic signature such that the signature icon is exhibited on the document at least when the document is printed or when the document is displayed on a display screen associated with a computing device or machine, wherein the signature icon facilitates authenticating the electronic signature of the signer.
