Many people, and not only computer system users, have heard about the concept of "data verification." What is it - most know only firsthand, applying this term exclusively to computer technology, often confused with the concepts of authentication and authorization. Here you will have to give a small explanation, which in the material below will be presented in the simplest possible language.
Data verification: what is it in a general sense?
To begin, consider the general meaning, without particularly going into a description of where such technologies can be used. In fact, this term comes from two Latin words (verus and facere), which form the corresponding phrase, and when combined, mean "verification / confirmation of the truth."
If you look more broadly at what verification of data means, then it is worth paying attention to such a moment: the approach of verifying or confirming the truth of some information can be applied in almost any area of modern human activity. We propose to consider several fundamental examples that will allow us to fully understand the essence of this term.
Information authentication: why is this needed?
Since we are talking about verifying and confirming any kind of information, at the present stage of the development of human society, this includes several main areas:
- general information about the person himself;
- registration documents;
- registration on Internet resources;
- information for banks and payment systems;
- compliance of a product or product with applicable regional or international standards;
- checking the conformity of the copy to the original and more
Data and customer verification: what is it in the banking sector?
The first thing to consider is the banking sector, because today many of us use loans, current accounts or the same plastic cards. Why was this topic originally addressed? Since the same aspect also includes checking the passport data of the person himself, which certifies his identity (this can equally be attributed to any other area).
But the banking sector is used solely as an example. Suppose you came to a bank with the aim of obtaining a loan or opening a current account in the form of a debit card. A bank employee asks for a passport and tax ID. After entering information into a computer program, the databases contained in the state registry are verified to verify your identity with the documents provided. It is clear that a fake passport, code, verbally indicated personal data will not pass the verification.
Using Online Verification
The question of what verification of data means when registering on Internet portals or in relevant services means that you initially provide true information about yourself in the sense of personal data and confirm registration. But there is one caveat.
In this case, a slightly different concept of data verification works. What is this from the point of view of confirmation, it is not difficult to understand, because when filling out the appropriate questionnaire you will be asked to enter your email address or mobile phone number, and then confirm your information by answering a letter or incoming SMS. Sometimes payment system owners may contact you personally.
In addition, there is another aspect related specifically to payment systems. The point here is that in some of them you will need to provide a photocopy of your passport, code and bank card to which electronic wallets will be linked. Here, data verification also works. What is this in this case? This is a regular check for compliance with the passport data of the registered subject and the holder of the wallet / card / account.
Please note that the authentication of the passport or code in this case does not pass verification , because the same WebMoney services can be used by people from countries scattered around the world, and the system will not be able to verify them with all its desire, even purely technically (it’s for this there simply will not be enough computing resources, not to mention blocking access to state databases).
The only thing the system can use is the issuance of a special certificate (usually obtaining a formal certificate is enough to use wallets and make a withdrawal of funds).
An example of using verification in application software
Now a few words about computers. We will not consider the compliance of the developed programs with any standards, but we will give one of the simplest examples based on the well-known program for recording information with burning a Nero Express optical disc.
For example, you decide to create an audio disc by adding the appropriate music tracks. Before burning, you can set the active parameter for checking data at the end of the process.
When the recording is completed, a window will appear in the program in which it will be indicated that verification of the data has begun. What is this in this situation? This is a check of the correspondence of the recorded files with the original original, not to mention testing the surface of the medium. In the case of a successful check, you can rest assured that the recorded disc can be reproduced without any problems not only in software, but also on household players.
Validation errors
If, in such a situation, a data verification error appears, this may indicate an incorrectly established recording method, physical damage to the medium, system failures, and more.
In the sense of errors that appear when identifying a user or client of a bank, in most cases this can also relate to problems with installed software or even to communication disruptions when accessing the Internet. When testing programs, such failures may relate solely to the fact that errors exist in the input code itself (even before the compilation was started). Most commonly used editors first underline lines with incorrect command syntax, and when compiling, they give a notification.
The same can be applied to the organization of local networks, when the central server cannot recognize all local terminals. There are many options, and correct such failures, taking into account each specific situation. It makes no sense to consider all of them, since it will take too much time.
Finally
It is hoped that the material presented above will allow many to understand what verification is, why it is needed. Today, such processes are ubiquitous. It is impossible to attribute them exclusively to our computer age, because the very concept and principles of using such technologies originated much earlier.
