Not all electronic signature methods have legal effect

Even: not everyone who provides electronic signature services has the corresponding qualifications and technology!

The development of electronic signatures

The wild growth of electronic signatures. In the early days, there were handwritten signatures on paper contracts, which were stored through scanning and saved through PS cutouts. Signature pictures with black text on a white background are used to copy and paste on documents that require signatures. Of course, these are illegal. After the country promulgated a formal electronic signature law, third-party platforms that provide legal electronic signatures have emerged one after another.

There are currently two main categories of legal electronic signature methods: digital certificate methods and biometric identification methods.

Digital signature: Through an institution with CA certification issued by the state, you can identify your identity and create a digital certificate that represents your identity. Such certificates can be used on electronic documents and contracts! Just like the official seal issued by the state is used on paper contracts, it has legal effect.

Biometric identification: Inputting handwritten signatures through electronic devices will collect multi-dimensional behavioral characteristic information such as strokes, stroke order, pen pressure, pen speed, and signing time of the signer during the writing process to form data. Package, after the collection is completed, the signature font has a handwriting recognition function. The biometric information of the signature is extracted through an algorithm. Through the principles of graphology, the cause of the handwriting can be traced and restored, the handwriting trend and writing habits can be analyzed, and intelligent comparison can be performed to effectively identify whether Signed for me.

The former requires physical media such as USB shields and certificates to achieve identity recognition, and its application scenarios are somewhat limited. In scenarios where unspecified people sign face-to-face and where documentary evidence needs to be left behind, the digital certificate method cannot It achieves its purpose of paperless signing very well, and at the same time, the dependence on physical hardware such as USB shield increases the cost of use.

Static identification cannot express wishes

Biometric identification technology is mainly divided into two categories. Static biometric identification methods are represented by fingerprints and facial recognition. Because of their objective attributes, It can express the behavior of "checking in" but cannot express the behavior of "confirmation";

As a dynamic behavioral biometric, handwriting has the advantage of actively expressing will, thus becoming an electronic signature biometric identity recognition and behavior confirmation. ideal way. Corresponding to the electronic signature method, it can express that the signature is only controlled by the person.

——Electronic signature of original handwriting

Based on the principle of traditional signature and combined with the advantages of electronic equipment to collect samples and save data, this electronic signature application scheme is proposed.

Compared with traditional handwriting identification, which emphasizes handwriting characteristics, electronic signatures are affected by the writing carrier and writing tools, and many handwriting characteristics will change. From an identification perspective, handwritten handwriting data is particularly important and even more valuable at the judicial level.
