What is a timestamp? What is a timestamp

A timestamp, usually a sequence of characters, uniquely identifies the time at a certain moment. Digital timestamp technology is a variant of digital signature technology.

Timestamp Definition:

Time is a very important information in e-commerce transaction documents. In a written contract, the date of signing the document is as important as the signature, and it is crucial to prevent the document from being forged and tampered with. Digital Time Stamping Service (DTS:

Digital Time Stamp Service is one of the online e-commerce security services, which can provide security protection for the date and time information of electronic documents.

In view of the current flood of fraudulent emails, email digital signatures bring trusted identities to each email, which is the only solution to the problem of email fraud, because digital signatures cannot be counterfeited and forged, especially for users who have completed identity authentication, the real name of the sender and the name of the organization will be displayed, ensuring that the recipient can easily be sure of the identity of the sender and will not be deceived by the impersonation of identity.

At present, the commonly used S MIME email signature and encryption standard does not support timestamp signatures, but MeSign believes that real-world emails are postmarked, and emails in the digital world should also be postmarked, so MeSign innovatively attaches MeSign timestamp signature to the digital signature data of user emails to prove the trusted time of the user's email, while the sending time of traditional emails is the time on the untrusted mail server. MeSign Email Timestamp Service is a free supporting service, which can be used in various application scenarios that need to prove the email sending time, and has the characteristics of anti-tampering, anti-forgery and non-repudiation of email sending time.

MeSign has optimized the performance based on the international standard RFC3161 timestamp technology, so that the timestamp data is only about 12% of the standard timestamp signature data (reduced by 88%), which is more suitable for mobile applications and fast verification of timestamp signatures. At the same time, we add technical protection measures to prevent the recovering timestamp from overwriting the original timestamp, which effectively ensures that the original timestamp data will not be replaced, and truly ensures the authenticity and non-repudiation of the email sending time.

Just as postal mail must be postmarked, sending emails should also be time-stamped.

Timestamps are data generated by digital signature technology, and the signed objects include the original file information, signature parameters, signature time, and other information. The timestamp system is used to generate and manage timestamps, and digitally sign the signed object to generate timestamps to prove that the original document existed before the signing time.

A trusted timestamp is an electronic certificate issued by the Joint Trust Timestamp Service Center to prove that the content of an electronic data file has remained intact and has not been altered since the trusted timestamp was applied. The issuance of the approval letter for trusted timestamp access marks the beginning of the standardized application of trusted timestamps in the field of archives, and will play the role of tamper-proof content of electronic archives and digital copies of archives and legal evidence to protect archives.

According to the requirements of the Electronic Signature Law on the original form of data messages, electronic documents, electronic archives or digital copies of paper archives that have applied for trusted timestamp authentication can be regarded as the original forms prescribed by the regulations.

It is generated by digital signature technology, and the object of signature mainly includes information such as signature time, signature parameters, and original file information.

The main function of the timestamp is to verify whether the data has been tampered with, which is also the main purpose of people to create it, it authenticates the time of a certain data generation through certain technical means, so as to determine whether the data has been tampered with after it is generated.

Therefore, the person providing the timestamp service must prove that the time source used in the service is trustworthy, so as to ensure that the timestamp service he provides is secure. A timestamp signature in a blockchain is written on an area in the blockchain. And it just so happens that one of the characteristics of blockchain is that the parts of the past cannot be changed or modified.

Therefore, the stability and reliability of the data in the blockchain are extremely high.

The timestamp is to use a string of numbers to represent the current time, for example: 1553102157 seconds represent 2019-03-21 01:15:57, how to convert, you can see and try it inside.

Timestamps for a successful e-commerce application can require that the parties involved in the transaction cannot deny their behavior. This involves placing a trustworthy timestamp on a digitally signed transaction to address a range of practical and legal issues. Since the user's desktop time can be easily changed, the timestamp generated by that time cannot be trusted, so an authoritative third party is needed to provide a trustworthy and non-repudiated timestamp service.

For details, see Timestamps.

A stamp that corresponds to a certain moment in time, is unique, and is measured in seconds.

What is a timestampWhat does it do?

Summary. A complete, verifiable piece of data that represents a piece of data that existed before a certain time is usually a sequence of characters that uniquely identifies the time at a certain moment. A timestamp is an encrypted document that is formed, and the timestamp does not change with the change of time zone, so the timestamp is the same no matter which time zone you are in.

In this way, we avoid the mistakes of repeatedly modifying the data. In order to achieve cross-platform, when recording time in the application system, we can also use the method of recording timestamps to achieve cross-platform.

In order to achieve cross-platform, when recording time in the application system, we can also use the method of recording timestamps to achieve cross-level fiber search.

Can you add, I don't quite understand it.

In layman's terms, a timestamp is a complete, verifiable piece of data that can and may not be enough to represent the existence of a data at a specific point in time. Time-stamp is a certificate document formed by an encrypted canton, which consists of three parts: 1. A digest of the file that needs to be timestamped; 2. The date and time of receipt of the documents by DTS; 3. DTS's digital signature.
