E-signature – the expression

A digital signature is an electronic version (Code) that the signature can be used for the identity of the sender of a message or a signed document, and to ensure that the original content of the message or document which was unchanged. Digital signatures are easily transportable, can not be imitated by someone else, and can be automatically schedule. The capacity that the original message suggested that the sender is not repudiation later.
A digital signature can be with any type of message, if it is encrypted or not, simply, that the recipient can not be sure of the identity of the sender and the message is intact. A digital certificate contains the digital signature of the authority issuing the certificate of the nature that anyone can understand that the certificate is a fact.
A formal definition: “(I) a value computed by an encryption algorithm and an annex with data, so that all recipients, the signature data for the origin and integrity.
(II) data in the Annex or cryptographic transformation of a unit of data to a data recipient to the proof of origin and data integrity and protect against forgery, eg by the recipient. ”

E-signature – How it works (with PKI)

They believe that the draft treaty to your lawyer in another city. Do you want your lawyer to insurance, but what you have and it really is.

1. You copy the treaty (a bit) in an e-mail seen.

2. Using special software, you receive a message hash (mathematical summary) of the Treaty.

3. Then, using a private key that you already have a public-private key to the Authority chopped.

4. The hash code is your digital signature of the message. (Note that this will be different each time you send a message.)

At the other end, your lawyer, who receives the message.

1. To ensure that you are intact, and you, your lawyer a hash of the message.

2. Your lawyer, then, with your public key to decrypt the message hash or summary.

3. If the hash of the game, the message is valid.

E-signature – The facts we should all know,

For various definitions of the electronic signature and the legislation passed so far, almost everyone has tried to technology independence to the present. But in general, it is also that the use of PKI retrofit should be considered a method of creating an electronic signature (digital signature) in the world.
The use of PKI has several advantages over other methods, which seem to be practical and safe industry and business, such a solution. The simplicity of the distribution of keys, irreversible hash algorithms and the combination of keys, a person who uses digital certificates, part of the trust (certificate authority) are the main contributors to this recipe.
A certification authority (CA) digital certificate information in the certificate, verifies the accuracy of the data channel of the digital certificate of a public key certificate and key to this publication, with its repository.
By written agreements intelligent CA is also responsible for liability on the certification of participants and parties, while the Internet browser’s most popular email clients and providing mechanisms for trust in an explicit or implicit .
In such scenarios, it is very important for everyone to ensure that the licenses that trust and argues that if a CA trust and the issuance of the Authority does not expire and / or withdrawal. Add expressly approved a list of required operating system is no less of hara-kiri.
CA is given its certification (PA) and practice Statement (CPS) and other agreements as the agreement of the participants and confidence in the agreement. Equally important is the fact that all parties must understand and know exactly what benefits and guarantees in individual contracts.
The digital certificate ensures that the key pair of digital signature to the person, the information in the certificate. The certificate in May of integration of a person in a company as trustee. This shows the dependence of trust on the part must be the certificate authority (CA) and their capacity, the verification certificate of the CA. It is an accepted and recommended as best practice, not to trust a certificate, which can not be checked for its validity, which means that the CA should be the validation certificate online in real time . Just CA provides lists CRL is not good enough for serious business.
Trusting CA is always a deliberate decision and must be on a good knowledge of the security of the CA itself, policy and practice on the certificate life cycle management, to recruit persons with access to sensitive information and territories (physical access), segregation of duties of staff, etc, a person in need, a digital signature should not be on all legal and contractual details, however, the person will be easier when there is a certain unity, external audit and accreditation of CA to be certified as trustworthy.

Conclusion

There is no doubt that we have a long way to go in improving these technologies to ensure the comfort and confidence in the parts of doing business by electronic documents and transactions throughout the other in the world, there is more need for governance in a new area for us all. And I am also satisfied with this (site), technologies, opportunities for such research practices, information gathering and business with such a speed, which would not have been possible just a few decades.

Advantages of setting up an EDI system

Establishment of an EDI system has three major advantages:

1. Increase speed
2. Greater accuracy
3. Cost Savings

Speed

One of the benefits most clearly in the implementation of EDI is a system by increasing productivity instantaneous speed data transmission system. The processing of orders or requests are no longer valid, a system with EDI, orders are processed and shipped the same day of receipt.

In many companies, EDI can be introduced so that data flows directly into the accounting or ERP, which makes data collection, monitoring, analysis and production efficient and almost effortless. It also produces a reduction of man-hours in almost all departments, including marketing, shipping and quality control.

Accuracy

A second advantage of EDI is the accuracy. Given that EDI over the same data on multiple targets, after a single data entry, fewer errors during input. Data are collected once a double review, and with work. It is not necessary, the same data several times in the door to errors.

Costs

Many companies, in-depth look at the cost-effectiveness in the implementation of an EDI system in most cases, to decide the Heads of State and Government for the implementation of the system. An EDI system can not only save money in the cost of consumption of paper and postage, but the increase in productivity through the use of the EDI system has important consequences.

EDI systems that are often necessary, the number of employees by the data, before the introduction of the system. This reduces the number of hours paid by the company.
In addition, because EDI increases productivity and requirements in a fraction of the time with traditional methods, customer satisfaction is much more once the results of companies and businesses acquired by the recommendations word of mouth that the company acquires a reputation for quick delivery of products. Fewer errors in processing information provides a higher percentage of customers exactly what they are mandated, as promised.

Since the integration of EDI with other departments within a company, the critical information in near real-time results. This ensures that data collected for analysis, monitoring and marketing is accurate, current and reliable, that the sales efforts and more effective.

The DFI is ideal for inventory control and purchasing of raw materials in production. Since these applications are, once an order or a product is sold, the equipment and the heads are more precise, what the collection of dust on the shelves. This allows better use of company resources and a production that flows well.

Other benefits, including respect for the environment in May, because paper consumption is reduced with an EDI system. In addition, with an EDI-May to do business globally, because the data in a few minutes in the world, if necessary.

Although EDI systems have a variety of desirable benefits, they have some drawbacks, too.

The disadvantages of EDI

Charges

An EDI system is a manifesto added to advance the expenses for the required software, installation and staff training. This cost can be strengthened if another program that is currently the company, should be changed for the new system. In addition, some companies in May needs in terms of infrastructure to improve the root of an EDI system. It is also the obvious need, acquisition and maintenance of system compatibility and web services for EDI.

Resources

Whatever system of EDI, a company needs expertise in the processing of EDI, to meet customer requirements and changes.

Regulation

For some businesses, EDI systems have recently led to an increase in staff supervision and community monitoring of DFI. These companies, which are subject to United States’ new health insurance portability and Accountability Act (HIPAA), must ensure that the EDI is a secure and confidential. This poses new challenges for laboratories , doctors, hospitals and other health care providers and their health care facilities.

EDI is a powerful tool for many companies. Using today’s technology allows companies to achieve these goals are just dreams before the implementation of EDI.
While EDI offers advantages in terms of time and money and increasing productivity, efficiency and customer satisfaction, it also represents a major challenge for companies. EDI implementation is for many companies, but on an individual basis.
