What is authentication

Authentication is the procedure which allows to carry out authentication of the data specified by the user. After successful passing of authentication the access to the restricted information on an Internet resource is provided to the user.

Principle of work

For authentication passing the user is offered to enter a combination of certain data, for example, the login and the password of the used account. Necessary information is entered by the visitor in a special HTML form. After clicking the input confirmation button the program of authentication sends the specified data to the server for comparison with the records which are available in base. If the combination which is stored on the website matches the in-fed information, readdressing of the user to the closed part of the website is carried out. At mismatch of the entered data the visitor is offered to execute authorization again.

The procedure of authentication is carried out for the purpose of providing certain rights to the user which not authorized guests do not have. After successful execution of an input the user can get access to a personal account in which he will have an opportunity to change the account information and to make advanced settings and operations. For example, after passing of authentication on social networks the user acquires the right to correspond and make publications on its own behalf.


Ways of authentication

For gaining access to the closed part of Internet service different methods of authentication which are selected according to safety requirements can be used.

Some resources suggest to execute authorization using automatically generated one-time password which goes to the user at the corresponding request. The numerical or text combination for implementation of an input goes through the SMS or by means of e-mail. Sometimes one-time passwords are generated by special eToken devices.

In the systems needing the raised security level the biometric authorization using scanning of an iris of the eye of an eye or a print of a palm is often used. The technology of automatic examination of handwriting or the user's voice is in certain cases applied. Also there are developments which allow to carry out authorization on DNA of the person.

Authentication process on the Internet is applied on such resources as web forums, blogs, social networks. Authorization using different ways is carried out in payment service providers, Internet banking, online stores and on some corporate resources. Depending on degree of security of the website and importance of information which is stored on it, different methods of gaining access can be implemented.
