Handwriting-based method for identity identification and terminal thereof

Abstract

The invention provides a handwriting-based method for identity identification and a terminal thereof. The method comprises the following steps that: a handwriting collection module collects to-be-identified handwriting; a feature extraction module extracts an identification feature of the to-be-identified handwriting, wherein the identification feature is used for characterizing specificity of the to-be-identified handwriting; a determination module determines whether the identification feature is matched with a standard feature of standard handwriting or not, wherein the standard feature is stored in a handwriting sample database; and if it is determined and obtained that the identification feature is matched with the standard feature, the identity is legal; If not, the identity is illegal and the standard feature is used for characterizing specificity of the standard handwriting. According to the method, handwriting is employed to carry out determination on legality of user identity; because handwriting of each person is unique and will not be changed randomly in a long time, stability of identity identification is ensured; in addition, handwriting is not easy to be imitated, sothat identity identification employing handwriting has high security.

Description

technical field [0001] The invention relates to identification technology, in particular to a handwriting-based identification method and terminal. Background technique [0002] With the rapid development of microelectronics technology, personal electronic products (such as smart phones, PDAs, tablet computers, etc.) with small size and rich functions and applications have become indispensable in people's daily work and life. Generally, necessary business information, private information, etc. are stored in the aforementioned personal electronic products. In order to prevent criminals from misappropriating personal electronic products and using the information stored in them to carry out illegal activities and bring losses to the owner or related personnel of personal electronic products, therefore, personal electronic products are generally equipped with identity verification devices. mechanism. [0003] Currently, the most widely used identity verification mechanism in p...

Problems solved by technology

[0004] Although fingerprint identification can be used to identify whether the user's identity is legal, fingerprints can also be changed through surgery or some invasive means, which leads to fingerprint identification is not a stable identification method. At this time, this finger can no longer be used for identification

In addition, some people's fingerprint features are difficult to image, resulting in difficult recognition and high misrecognition rate

In addition, every time fingerprint recognition is used, the fingerprints of the user will be left on the fingerprint recognition collection head, and these fingerprints left on the fingerprint recognition collection head can be used to copy fingerprints. Once the fingerprints are copied, Then anyone can use the copied fingerprints for identity identification, which reduces the security of fingerprint identification
