The scope of information security software and hardware covers 4 aspects:

1. Application and data security: including identity authentication, authorization management, and data security protection;

2. Host and system security: including standard system security, vulnerability scanning and reinforcement, virus prevention, and host security supervision;

3. Network security: including network boundary security, VPN (virtual private network), and firewall;

4. Physical and environmental security: access control system, camera surveillance, physical environment.

Information security aims at authenticity, confidentiality and security. The role of electronic certification agencies in information security is to issue electronic visa certificates to users and provide users with functions such as member identity verification and key management.

Reliable electronic signatures need to be tamper-proof and non-repudiation. The former can ensure data consistency and prevent data from being tampered with, and the latter can establish an effective liability mechanism to prevent users from denying their actions. So, can a paper contract be considered an electronic contract after being photographed/scanned? Of course not. In fact, a digital signature cannot be equated to a digital image of a written signature. It is an electronic signature of an electronic document through cryptographic technology.

Electronic certification, like electronic signatures, is a security mechanism in e-commerce. It is a service provided by a specific organization to verify the authenticity of electronic signatures and their signers.

Real-name authentication is also a key technology for the platform to ensure information security and comply with the definition of "reliable electronic signature". Taking our platform as an example, the real-name authentication method includes facial recognition, identity information, bank card, EID and other authentication methods. After a digital certificate with individual identification significance is issued to an individual or corporate user, the contracting parties can complete the entire contracting operation such as signing and sealing the electronic document online. This electronic document is a legal and valid electronic document that can be used as evidence for rights protection. contract.

A reliable electronic contract, in addition to ensuring that the signature is authentic and the content cannot be tampered with, must also ensure the accuracy of the time, which involves time stamp technology. Trusted timestamps are national legal time sources responsible for ensuring time service and punctuality monitoring. No organization, including the timestamp center, can modify the time to ensure the authority of the time. Only the timestamps generated in this way have legal effect. The core technology of timestamp technology is still digital signature technology.
