The workflow form handwritten signature control has passed the certification of the Ministry of Public Security. The former can upload a Word attachment to a personal filing cabinet, and then click the Edit button to experience the handwritten signature effect.

Question 2: What is an electronic signature? In order to understand what an electronic signature is, we need to start with the traditional manual signature or stamp. In traditional commercial transactions, in order to ensure the security and authenticity of the transaction, it is necessary to have a written contract or official document signed or sealed by the parties or the person in charge, so that both parties can identify who signed the contract and ensure that the signer or seal recognizes the contents of the contract, thus making the contract legally valid. In the virtual world of e-commerce, contracts or documents are expressed and transmitted in the form of electronic documents. In electronic documents, the traditional handwritten signature and seal can not be carried out, and it must be replaced by technical means. Legally speaking, signature has two functions: identifying the signer and indicating the signer's approval of the contents of the document. Therefore, UNCTAD's Model Law on Electronic Signatures defines an electronic signature as: an electronic signature refers to data contained in, attached to or logically associated with a data message, which can be used to identify the signer related to the data message and show that the signer approves the information contained in the data message. ; The definition of electronic signature in EU Framework Directive on Electronic Signature is: data attached in electronic form or logically linked with other electronic data as an authentication method. Different laws may have different definitions of electronic signature, but the essence is the same. Therefore, an electronic technical means that can identify the true identities of both parties in electronic documents, ensure the security, authenticity and non-repudiation of transactions, and play the same role as handwritten signatures or seals can be called electronic signatures. At present, there are many technical means to realize electronic signature, such as digital signature based on public key cryptography; Or use unique identification marks based on biometrics, such as fingerprints, voiceprints or retinal scans; Pattern recognition of electronic images of handwritten signatures and seals: cryptographic codes representing identity (symmetric algorithm); Computers based on quantum mechanics and so on. However, the relatively mature electronic signature technology widely used in advanced countries in the world is still digital signature technology based on PKI. Due to the principle of technical neutrality in making laws, the signature mentioned in the current electronic signature law generally refers to digital signature. It is a special form of electronic signature. The so-called digital signature is a series of symbols and codes generated by some cryptographic operation to form an electronic password for signature, rather than writing a signature or seal. Technically, this kind of electronic signature can also be verified by algorithm, and its verification accuracy is unmatched by manual signature and seal in the physical world. In ISO7498-2 standard, digital signature is defined as: some data attached to a data unit, or cryptographic transformation of the data unit, which allows the receiver of the data unit to confirm the source and integrity of the data unit and protect the data from being forged by people (such as the receiver). The definition of digital signature in American Electronic Signature Standard (DSS, FIPS 186-2) is that data is calculated by using a set of rules and a parameter, and the identity of the signer and the integrity of the data can be confirmed by this result. According to these definitions, digital signature has become the most widely used, most mature and most operable electronic signature method in e-commerce and e-government. It uses standardized procedures and scientific methods to identify the signer and approve the electronic data content. It can also verify whether the original text of the file has changed during transmission, and ensure the integrity, authenticity and non-repudiation of the transmitted data.

Question 3: What does the electronic signature of driving school mean? It refers to the existence in electronic form, attached to the electronic document and logically associated with it, which can be used to identify the identity of the signer of the electronic document, ensure the integrity of the document, and show that the signer agrees with the factual content stated in the electronic document. Electronic signature is not a digital image of handwritten signature and seal, it exists in the form of electronic code and must be bound with digital certificate.

Question 4: What does electronic seal mean? Electronic seal technology is to simulate the traditional physical seal with advanced digital technology, and its management and use methods are in line with the habits and experiences of physical seals. Electronic documents stamped with seals have the same appearance, the same effect and similar usage as paper documents stamped with physical seals.

Question 5: Application of Electronic Signature With the popularity of the Internet and the rapid development of various e-commerce activities and e-government activities, electronic signatures have been widely used in various fields, mainly including: sending secure e-mail, visiting secure websites, online bidding, online signing, online ordering, secure online file transmission, online payment, online tax payment, online stock trading, online shopping and online customs declaration. The practice in developed countries is mainly solved by electronic signature. In fact, the electronic signature itself is not a "signature", but an asymmetric public key security system, and its operation mode is essentially a mathematical operation. Here, encryption refers to a technical process of hiding the transmitted information content-that is, closely combining the mathematically existing relationship with a key (public key and private key). Take the telecom industry as an example, and adopt Youpai 10. 1? PD 10 1 1 electromagnetic pen display, and implemented in the service counters of major business halls in China. In the past, customers had to fill out multiple paper forms for telecom tariff adjustment, international roaming service, downtime treatment and other businesses in the business hall. This not only increases the process for tellers and customers to fill in the identification information repeatedly, prolongs the waiting time in line, but also increases the expenditure of paper cost, which greatly affects the overall service efficiency. Through the integration of paperless electronic signature, customers can directly complete form filling, contract confirmation and electronic handwritten signature on the screen in a digital way, and tellers can also store contracts and other documents in the company as electronic documents for systematic filing, which effectively improves the quality and overall efficiency of China Mobile's internal business document management and external customer service. Electronic seal management: including seal making, seal information management, seal distribution, seal loss reporting, seal deactivation and re-making. Organization user management: it has the function of managing organizations, users and administrators; Stamping: the document is stamped and signed to prove the identity of the signatory; Verify the signature: verify the signature of the document and confirm the validity of the document; Log audit: record all functional modules in the system, and provide log query and audit functions. Electronic signature management system (server): Respond to various management requests from management clients, including administrator's request for signature service, auditor's request for auditing logs and user's request for updating information. Electronic signature management system (client): database configuration, personnel management, certificate configuration, service management, signature review, seal management, log review, log cleaning, seal submission, information update and other operations can be carried out to realize seal life cycle management in the system. Signature service program: authenticate the identity of the electronic signer, provide time stamp service and verification service for the signature request of the signing client, and provide root certificate and CRL download service for the client. Stamp making tool: Make a stamp and save it as a picture file, so as to import it into the smart password key or database later. Signature application client: It is a set of secure application software developed based on smart key, which is used to ensure the integrity, tamper resistance and non-repudiation of application documents. Electronic seal can achieve the same display effect as paper seal or signature through complex image processing. Personal electronic signature, company electronic signature, company employee electronic signature, server certificate, VPN certificate, WAP certificate, code signing certificate, and form signing certificate.

Question 6: What is the principle of electronic signature? Electronic signature (also known as public key digital signature and electronic signature) is an ordinary physical signature, similar to the signature written on paper, but it is realized by using the technology in the field of public key encryption, which is used to identify digital information. A set of digital signatures usually defines two complementary operations, one for signing and the other for verification.

Electronic signature is a digital string, which can only be generated by the sender of information, and others cannot forge it. This number string is also an effective proof of the authenticity of the information sent by the information sender.

Digital signature is the application of asymmetric key encryption technology and digital digest technology. The vendors providing electronic signatures are third-party electronic authentication service providers such as bjca.

Question 7: What do you mean there is no electronic signature file on the disk? The file is missing.

Question 8: What are the advantages of electronic seal? 1. Convenient. Based on computer and network technology, ESCA electronic seal can realize the high informationization of seal management and signature process, and can transmit signature files in different places conveniently and quickly, which greatly improves work efficiency. Only taxpayers who use electronic seals can cancel the paper declaration procedure and realize the tax declaration method of staying at home. 2. Safety. Adopt international advanced digital signature technology; It has achieved high-strength security indicators such as the contents of the signature file cannot be tampered with and the seal imprint cannot be copied, making the signature file unique and preventing illegal acts such as forging files to the maximum extent. 3. Reliability. Based on the computer's function of data storage, processing and retrieval of information, ESCA electronic seal can supervise the whole signing process, accurately query the detailed operation records left in the data center of the Ministry of Public Security during each signing process, and ensure that the signing process is undeniable. At present, the application scope of ESCA electronic seal includes: e-commerce, e-government, electronic bills (including industry and commerce, taxation, customs, medical care, banking, social security, transportation, etc. ). If the electronic seal holder uses the seal in the application systems of "China Electronic Seal Public Security Appraisal System Unified Platform", which leads to disputes and controversies, local judicial institutions can submit the Electronic Signature Data Message Appraisal Report to the Material Evidence Appraisal Center of the Ministry of Public Security, and issue a legally binding Electronic Signature Data Message Appraisal Report as the basis for judicial decisions.

Question 9: How does the official seal in an electronic signature have legal effect? Electronic seal, electronic signature, electronic seal and electronic official seal have no legal effect. Electronic seal, electronic signature, electronic seal, etc. It is only a visual graphic effect and has no legal effect, because they can be tampered with, forged or ps at any time. What really has the legal effect given by the electronic signature law is the hash value formed after the electronic signature of electronic documents. If it is not clear, it can be understood that China Yunqian has a legally binding electronic contract.
