When using WPS characters and Word characters to balance daily work, it is often necessary to make various documents. When concluding a contract or writing an application, it is sometimes necessary to hand-write the applicant's signature, so when the applicant is not at the scene, it is necessary to make a hand-written name where the country stops the applicant's hand-written signature. Because now is the digital age, even personal signatures often use electronic signatures instead of handwritten signatures.

The method of computer wps electronic handwritten signature is as follows:

1. Open the electronic contract file of WPS document and click Insert-Picture.

2. After inserting the autographed picture, click the picture layout option, and the album will be placed under the text.

3. Move the picture to the appropriate location.

4. Click on the picture, click on the picture tool above, and click on the color.

5. Click Set to Black and White.

6. In this way, the handwritten signature item is set.

First, open the Zen master's brain and import the signature into a blank document; Click the right mouse button after the image is successfully imported, and set it to float above the text; Click the format in the toolbar, click the color, set the transparent color, and the electronic signature will be set.

Digital edition

brief introduction

Simply put, the so-called digital signature is some data attached to the data unit, or the cryptographic transformation of the data unit. This kind of data or transformation allows the receiver of the data unit to confirm the source and integrity of the data unit, and protects the data from being forged by people (such as the receiver).

This is a method of signing an electronic message, and the signed message can be transmitted in a communication network. Digital signature can be obtained based on both public key cryptosystem and private key cryptosystem, mainly digital signature based on public key cryptosystem. Include general digital signature and special digital signature.

Common digital signature algorithms for lotus potatoes include RSA, ElGamal, Fiat-Shamir, Guillou-Quisqour, Schnorr, Ong-Schnorr-Shamir, Des/DSA, elliptic curve digital signature algorithm and finite automaton digital signature algorithm.

Special digital signatures include blind signature, proxy signature, group signature, Lu Li undeniable signature, fair blind signature, threshold signature, message recovery function signature, etc. These signatures are closely related to the specific application environment.

Obviously, the application of digital signature involves legal issues, and the federal government of the United States has formulated its own digital signature standard (DSS) based on the discrete logarithm problem over a finite field. Some countries, such as France and Germany, have enacted digital signature laws.
